Description

[0001] This application is a divisional application. The original application has the application number 202011045420.3 and the original application date is September 28, 2020. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of audio, and more particularly to a method for configuring headphone channels, headphone components, and a computer-readable storage medium. Background Technology

[0003] In traditional headphones, one earbud has a fixed left channel and the other has a fixed right channel. Users often need to distinguish between the two earbuds, wearing the left earbud in the left ear and the right earbud in the right ear, in order to listen to multi-channel audio. If they wear them incorrectly, they have to remove both earbuds and put them back on, which reduces user efficiency. Summary of the Invention

[0004] This application provides a method for configuring headphone channels, a headphone assembly, and a computer-readable storage medium. The headphone assembly can configure the channels of headphones inserted into the left and right earphone compartments. When using the headphones, users can directly remove the earphone from the left earphone compartment and wear it in the left ear, and remove the earphone from the right earphone compartment and wear it in the right ear, thus listening to multi-channel audio normally, improving user efficiency and experience.

[0005] In a first aspect, this application provides a method for configuring headphone channels, applied to a headphone assembly. The headphone assembly includes a headphone case and two earphones. The headphone case has a left earphone compartment and a right earphone compartment, which are respectively used to accommodate the two earphones. The method for configuring headphone channels includes:

[0006] The headphone assembly detects that an earphone has been placed in the left earphone compartment and configures the earphone placed in the left earphone compartment as the left channel;

[0007] The headphone assembly detects that an earphone has been placed in the right earphone compartment and configures the earphone placed in the right earphone compartment as the right channel.

[0008] In the headphone channel configuration method shown in this application, the user can freely place two headphones into the left and right headphone compartments respectively. The headphone assembly can configure the headphone placed in the left compartment as the left channel and the headphone placed in the right compartment as the right channel. When using the headphones, the user can directly wear the headphone placed in the left compartment in the left ear and the headphone placed in the right compartment in the right ear, allowing the user to listen to multi-channel audio normally. This avoids the sound field distortion problem caused by playing audio information from non-corresponding channels, and helps to improve the realism of the sound source and the audiovisual effect.

[0009] In one embodiment, the step of the earphone assembly detecting that an earphone has been inserted into the left earphone compartment and configuring the earphone inserted into the left earphone compartment as the left channel includes:

[0010] The earphone case detects that an earphone has been inserted into the left earphone compartment and sends the first signal;

[0011] The earphone placed in the left earphone compartment responds to the first signal and is configured as the left channel.

[0012] The steps for the headphone assembly to detect the insertion of an earphone into the right earphone compartment and configure the earphone placed in the right earphone compartment as the right channel include:

[0013] The earphone case detects that an earphone has been inserted into the right earphone compartment and sends a second signal;

[0014] The earphone placed in the right earphone compartment responds to the second signal and is configured as the right channel.

[0015] In the headphone channel control method described in this embodiment, the headphone case sends a first signal to the earphone placed in the left earphone compartment and a second signal to the earphone placed in the right earphone compartment, so that the earphones placed in the left and right earphone compartments are configured with matching channels. When using the headphones, the user can directly wear the earphone placed in the left earphone compartment in the left ear and the earphone placed in the right earphone compartment in the right ear. The earphones worn in the left and right ears will then output audio from the corresponding channels, which can effectively avoid sound field disorder caused by playing audio information from non-corresponding channels, and improve the user's efficiency and user experience.

[0016] In one embodiment, each earphone includes a housing and two charging terminals, which are exposed relative to the housing and spaced apart from each other.

[0017] The earphone case includes two left-side power supply terminals, two right-side power supply terminals, a storage module, and a voltage detection module. The two left-side power supply terminals protrude from the groove wall of the left earphone compartment and are spaced apart from each other, for contacting the two charging terminals of the earphones respectively. The two right-side power supply terminals protrude from the groove wall of the right earphone compartment and are spaced apart from each other, for contacting the two charging terminals of the earphones respectively. The storage module is used to store a preset voltage difference.

[0018] The steps for the headphone case to detect the insertion of an earphone into the left earphone compartment and send the first signal include:

[0019] The voltage detection module detects that the voltage difference between the two left-side power supply terminals is equal to or greater than the preset voltage difference, and the earphone box sends the first signal.

[0020] The steps for the headphone case to send a second signal after detecting that an earphone has been inserted into the right earphone compartment include:

[0021] The voltage detection module detects that the voltage difference between the two right-side power supply terminals is equal to or greater than the preset voltage difference, and the earphone box sends a second signal.

[0022] It should be understood that when an earphone is inserted into the left earphone compartment, the two left-side power supply terminals come into contact with the two charging terminals of the earphone inserted into the left earphone compartment to conduct electricity, resulting in a voltage difference between the two left-side power supply terminals. Similarly, when an earphone is inserted into the right earphone compartment, the two right-side power supply terminals come into contact with the two charging terminals of the earphone inserted into the right earphone compartment to conduct electricity, resulting in a voltage difference between the two right-side power supply terminals. Therefore, the earphone case can determine whether earphones are inserted into the left and right earphone compartments by detecting the voltage difference between the two left-side power supply terminals and the two right-side power supply terminals.

[0023] In one embodiment, the earphone case uses a pressure detector or an infrared light sensor to detect whether earphones are inserted into the left and / or right earphone compartments.

[0024] In one embodiment, the earphone case includes a left detection module and a right detection module, the left detection module corresponding to the left earphone compartment and the right detection module corresponding to the right earphone compartment.

[0025] The steps for the headphone case to detect that an earphone has been inserted into the left earphone compartment and send the first signal include: the earphone sending a detection signal;

[0026] The left-side detection module detected the detection signal, and the earphone box sent the first signal.

[0027] The steps for the headphone case to send a second signal after detecting that an earphone has been inserted into the right earphone compartment include:

[0028] The headphones send a detection signal;

[0029] The right-side detection module detected the detection signal, and the earphone box sent a second signal.

[0030] In one embodiment, the earphone case includes a left contact terminal and a right contact terminal, the left contact terminal protruding relative to the recessed wall of the left earphone compartment, and the right contact terminal protruding relative to the recessed wall of the right earphone compartment. Each earphone includes a contact terminal for abutting against either the left or right contact terminal.

[0031] The steps for sending the first signal include:

[0032] The earphone case sends a first signal to the earphone inserted into the left earphone compartment via the left contact terminal.

[0033] The steps for configuring the earphone inserted into the left earphone compartment to the left channel in response to the first signal include:

[0034] The earphone inserted into the left earphone compartment receives a first signal through a contact terminal and, in response to the first signal, is configured as the left channel.

[0035] The steps for sending the second signal include:

[0036] The earphone case sends a second signal to the earphone inserted into the right earphone compartment via the right contact terminal.

[0037] The steps for configuring the earphone inserted into the right earphone compartment to respond to the second signal and be set to the right channel include:

[0038] The earphone inserted into the right earphone compartment receives a second signal via a contact terminal and, in response to the second signal, is configured as the right channel.

[0039] In one embodiment, the step of configuring the earphone inserted into the left earphone compartment as the left channel in response to a first signal includes:

[0040] The earphone inserted into the left earphone compartment is checked to see if it is configured as the left channel.

[0041] If yes, then the system remains in the left channel in response to the first signal; otherwise, the system switches to the left channel in response to the first signal.

[0042] The steps for configuring the earphone inserted into the right earphone compartment to respond to the second signal and be set to the right channel include:

[0043] The system detects whether the earphone inserted into the right earphone compartment was previously configured as the right channel. If so, it responds to the second signal and remains in the right channel; otherwise, it responds to the second signal and switches to the right channel.

[0044] In the headphone channel configuration method shown in this embodiment, the headphone inserted into the left or right headphone compartment first detects whether its channel type before configuration is the target channel type, and then performs channel configuration based on the detection result. When the headphone's channel type before configuration is consistent with the target channel type, the step of configuring the headphone channel can be saved, which helps to simplify the process of the headphone channel configuration method.

[0045] In one embodiment, the step of configuring the earphone inserted into the left earphone compartment as the left channel in response to a first signal includes:

[0046] The earphone placed in the left earphone compartment responds to the first signal and resets to the left channel.

[0047] The steps for configuring the earphone inserted into the right earphone compartment to respond to the second signal and be set to the right channel include:

[0048] The earphone placed in the right earphone compartment responds to the second signal and resets to the right channel.

[0049] In the headphone channel configuration method shown in this embodiment, the headphone placed in the left or right headphone compartment directly resets the channel type to the target channel type according to the signal sent by the headphone box. There is no need to detect whether the channel before headphone configuration is the target channel type, which eliminates the channel detection process and helps to simplify the headphone channel configuration method.

[0050] In one embodiment, the step of the earphone assembly detecting that an earphone has been inserted into the left earphone compartment and configuring the earphone inserted into the left earphone compartment as the left channel includes:

[0051] The earphone case detected that an earphone was placed in the left earphone compartment;

[0052] The headphone case detects whether the earphones placed in the left earphone compartment are configured as the left channel.

[0053] If yes, end the channel configuration; otherwise, send a channel switching signal.

[0054] The earphone placed in the left earphone compartment responds to the channel switching signal and switches to the left channel.

[0055] The steps for the headphone assembly to detect the insertion of an earphone into the left earphone compartment and configure the earphone placed in the left earphone compartment as the left channel include:

[0056] The earphone case has detected that an earphone has been inserted into the right earphone compartment.

[0057] The headphone case detects whether the earphone inserted into the right earphone compartment is configured as the right channel.

[0058] If yes, end the channel configuration; otherwise, send a channel switching signal.

[0059] The earphone placed in the right earphone compartment responds to the channel switching signal and switches to the right channel.

[0060] In the headphone channel configuration method shown in this embodiment, the headphone case first detects whether the channel type of the headphone placed in the left or right headphone compartment before configuration is the target channel type, and then performs channel configuration based on the detection result. When the channel type of the headphone before configuration is consistent with the target channel type, the channel configuration can be directly ended, saving the headphone channel configuration steps and helping to simplify the headphone channel configuration process.

[0061] In one embodiment, the step of the earphone assembly detecting that an earphone has been inserted into the left earphone compartment and configuring the earphone inserted into the left earphone compartment as the left channel includes:

[0062] The earphones have been detected as being inserted into the left earphone compartment and have been configured for the left channel.

[0063] The steps for the headphone assembly to detect the insertion of an earphone into the right earphone compartment and configure the earphone placed in the right earphone compartment as the right channel include:

[0064] The earphones have detected that the right earphone compartment has been inserted and have been configured as the right channel.

[0065] In the headphone channel control method described in this embodiment, the headphones themselves detect whether they are inserted into the left or right earphone compartment and automatically configure themselves to the matching channel based on the detection result. When using the headphones, the user can directly wear the earphone inserted into the left earphone compartment in the left ear and the earphone inserted into the right earphone compartment in the right ear. The earphones worn in the left and right ears will then output audio from the corresponding channels, effectively avoiding sound field distortion caused by playing audio information from non-corresponding channels, thus improving user efficiency and experience.

[0066] In one embodiment, two earphones are electrically connected to a terminal, and the method for configuring the earphone channels further includes:

[0067] The terminal identifies the earphone worn in the left ear and the earphone worn in the right ear;

[0068] The terminal sends a third signal to the earphone worn in the left ear, the third signal being used to indicate that the earphone worn in the left ear is configured as the left channel;

[0069] The terminal sends a fourth signal to the earphone worn in the right ear, which is used to indicate that the earphone worn in the left ear is configured for the right channel.

[0070] When using the headphones, users do not need to consciously distinguish between the left and right earpieces; they can freely wear the two earpieces in the left and right ears respectively. The terminal can identify the earpiece worn in the left and right ears, sending a third signal to the earpiece worn in the left ear and a fourth signal to the earpiece worn in the right ear. The two earpieces can automatically configure their audio channels according to the signals sent by the terminal to listen to multi-channel audio normally. This avoids the problem of sound field disorder caused by playing audio information in non-corresponding channels, which helps to improve usage efficiency and user experience.

[0071] In one embodiment, each earphone includes an information acquisition module for acquiring heartbeat propagation signals at the wearing position of the earphone.

[0072] The steps for the terminal to determine which earphone is worn in the left ear and which is worn in the right ear include:

[0073] The terminal compares the heartbeat propagation signals of the two earphones at their wearing positions and determines that, within the same signal cycle, the earphone whose heartbeat propagation signal arrives earlier at its preset position is worn in the left ear, and the earphone whose heartbeat propagation signal arrives later at its preset position is worn in the right ear.

[0074] It should be understood that the human heart is located on the left side of the body, and the path of the heartbeat from the heart to the left ear is shorter than the path to the right ear. Accordingly, if we compare the heartbeat signal at the left ear location with the heartbeat signal at the right ear location, we can see that at a preset position within the same signal cycle, the heartbeat signal at the left ear will precede the heartbeat signal at the right ear. This allows us to determine whether the earphone is worn on the left ear or the right ear.

[0075] When using the headphones, users do not need to consciously distinguish between the left and right earphones; they can freely wear the two earphones in the left and right ears respectively. The information acquisition modules of the two earphones respectively obtain the heartbeat transmission signal of the earphone wearing position. The terminal can determine which earphone is worn in the left ear and which is worn in the right ear based on the heartbeat transmission signal of the two earphone wearing positions. The two earphones can automatically configure the audio channels according to the signal sent by the terminal to listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information in the wrong channel, which helps to improve usage efficiency and user experience.

[0076] In one embodiment, the earphone includes an earbud, an ear stem, and an information acquisition module. The ear stem is fixedly connected to the earbud, and the information acquisition module is housed inside the earphone or the ear stem to acquire gravitational acceleration information of the earphone during wear.

[0077] The steps for the terminal to determine which earphone is worn in the left ear and which is worn in the right ear include:

[0078] Based on the gravitational acceleration information of the two earphones during the wearing process, the terminal obtains the deflection direction of the wearing position of the two earphones relative to the direction of gravity, determines that the earphone whose wearing position is deflected clockwise relative to the direction of gravity is worn in the left ear, and determines that the earphone whose wearing position is deflected counterclockwise relative to the direction of gravity is worn in the right ear.

[0079] It should be understood that, due to the inclusion of the earpiece, the structure of headphones has certain limitations, meaning they have limited points. This means that when a user wears headphones, they cannot rotate 360° around the ear canal; they can only rotate within a certain range. Since the user's left and right ears are mirror-symmetrically positioned, when the user puts the two headphones on their left and right ears respectively, they will rotate the two headphones in opposite directions until both are in the correct position. At this time, the gravitational acceleration information of the headphones will change. Therefore, the difference in gravitational acceleration information during the wearing process can be used to distinguish between the headphones worn on the left and right ears.

[0080] When using the headphones, users do not need to consciously distinguish between the left and right earbuds; they can freely wear the two earbuds in the left and right ears respectively. The information acquisition modules of each earbud obtain the gravitational acceleration information during the wearing process. The terminal can determine which earbud is worn in the left and right ears based on the two gravitational acceleration information during the wearing process. The two earbuds can automatically configure the audio channels according to the signals sent by the terminal to listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information in the wrong channel, which helps to improve usage efficiency and user experience.

[0081] In one embodiment, the method for configuring headphone channels further includes:

[0082] The two earphones were detected to be worn in the left and right ears respectively.

[0083] The two earphones are designated as the one worn in the left ear and the one worn in the right ear.

[0084] The earphone worn in the left ear is configured for the left channel;

[0085] The earphone worn on the right ear is configured for the right channel.

[0086] When using headphones, users do not need to distinguish between the left and right earphones. They can wear the two earphones on the left and right earphones respectively. The headphones can detect whether they are worn on the left or right ear and automatically configure the corresponding audio channel to listen to multi-channel audio normally. This avoids the problem of sound field disorder caused by playing audio information on the wrong channel, which helps to improve usage efficiency and user experience.

[0087] In one embodiment, each earphone includes an in-ear detection module for detecting whether the earphone is in-ear.

[0088] The steps for the two earphones to detect that the two earphones are worn in the left and right ears respectively include:

[0089] Both earphones' in-ear detection modules detected that the earphones were in the ear.

[0090] It should be understood that stereo playback is not possible when only one earphone is worn, and there is no need to configure the earphone's channel type. The earphone will only detect its own wearing position and configure the corresponding channel based on the wearing position if and only when the two earphones are worn in the left and right ears respectively, that is, when the in-ear detection module of both earphones detects that both earphones are in the ear.

[0091] In one embodiment, configuring the earphone worn in the left ear as the left channel includes:

[0092] The earphone worn in the left ear detects whether it was in the left channel before configuration. If so, it remains in the left channel; otherwise, it switches to the left channel.

[0093] The steps to configure the earphone worn in the right ear as the right channel include:

[0094] The earphone worn on the right ear detects whether it was in the right channel before configuration. If so, it remains in the right channel; otherwise, it switches to the right channel.

[0095] In the headphone channel configuration method shown in this embodiment, the headphone worn on the left or right ear first detects whether its channel type before configuration is the target channel type, and then performs channel configuration based on the detection result. When the headphone's channel type before configuration is consistent with the target channel type, the step of configuring the headphone channel can be saved, which helps to simplify the process of the headphone channel configuration method.

[0096] Secondly, this application also provides another method for configuring headphone channels, applied to a headphone assembly. The headphone assembly includes a headphone case and two earphones. The headphone case has a left earphone compartment and a right earphone compartment, which are respectively used to accommodate two earphones. The method for configuring headphone channels includes:

[0097] The earphone assembly detected that earphones were inserted into both the left and right earphone compartments.

[0098] The headphone assembly configures the earphone placed in the left earphone compartment as the left channel and the earphone placed in the right earphone compartment as the right channel.

[0099] In the headphone channel configuration method shown in this application, the user can freely insert two headphones into the left and right earphone compartments respectively. When the headphone assembly detects that headphones are inserted into both the left and right earphone compartments, it can configure the headphone in the left earphone compartment as the left channel and the headphone in the right earphone compartment as the right channel. When using the headphones, the user can directly wear the headphone in the left earphone compartment in the left ear and the headphone in the right earphone compartment in the right ear, allowing the user to listen to multi-channel audio normally. This avoids the sound field distortion problem caused by playing audio information from non-corresponding channels, and helps to improve the realism of the sound source and the audiovisual effect.

[0100] In one embodiment, the step of the earphone assembly detecting that both the left and right earphone compartments are filled with earphones includes:

[0103] The earphone placed in the left earphone compartment responds to the first signal and is configured as the left channel;

[0104] The earphone placed in the right earphone compartment responds to the second signal and is configured as the right channel.

[0105] In the headphone channel control method described in this embodiment, the headphone case sends a first signal to the earphone placed in the left earphone compartment and a second signal to the earphone placed in the right earphone compartment, so that the earphones placed in the left and right earphone compartments are configured with matching channels. When using the headphones, the user can directly wear the earphone placed in the left earphone compartment in the left ear and the earphone placed in the right earphone compartment in the right ear. The earphones worn in the left and right ears will then output audio from the corresponding channels, which can effectively avoid sound field disorder caused by playing audio information from non-corresponding channels, and improve the user's efficiency and user experience.

[0106] In one embodiment, each earphone includes a housing and two charging terminals, which are exposed relative to the housing and spaced apart from each other.

[0107] The earphone case includes two left-side power supply terminals, two right-side power supply terminals, a storage module, and a voltage detection module. The two left-side power supply terminals protrude from the groove wall of the left earphone compartment and are spaced apart from each other, for contacting the two charging terminals of the earphones respectively. The two right-side power supply terminals protrude from the groove wall of the right earphone compartment and are spaced apart from each other, for contacting the two charging terminals of the earphones respectively.

[0116] In the headphone channel configuration method shown in this embodiment, the headphone inserted into the left or right headphone compartment first detects whether its channel type before configuration is the target channel type, and then performs channel configuration based on the detection result. When the headphone's channel type before configuration is consistent with the target channel type, the step of configuring the headphone channel can be saved, which helps to simplify the process of the headphone channel configuration method.

[0121] In the headphone channel configuration method shown in this embodiment, the headphone placed in the left or right headphone compartment directly resets the channel type to the target channel type according to the signal sent by the headphone box. There is no need to detect whether the channel before headphone configuration is the target channel type, which eliminates the channel detection process and helps to simplify the headphone channel configuration method.

[0129] In the headphone channel configuration method shown in this embodiment, the headphone case first detects whether the channel type of the headphone placed in the left or right headphone compartment before configuration is the target channel type, and then performs channel configuration based on the detection result. When the channel type of the headphone before configuration is consistent with the target channel type, the channel configuration can be directly ended, saving the headphone channel configuration steps and helping to simplify the headphone channel configuration process.

[0130] In one embodiment, the step of the earphone assembly detecting that both the left and right earphone compartments are filled with earphones includes:

[0132] The steps for configuring the earphone inserted into the left earphone compartment as the left channel and the earphone inserted into the right earphone compartment as the right channel include:

[0133] The earphones placed in the left earphone compartment are configured for the left channel, and the earphones placed in the right earphone compartment are configured for the right channel.

[0134] In the headphone channel control method described in this embodiment, the headphones themselves detect whether they are inserted into the left or right earphone compartment and automatically configure themselves to the matching channel based on the detection result. When using the headphones, the user can directly wear the earphone inserted into the left earphone compartment in the left ear and the earphone inserted into the right earphone compartment in the right ear. The earphones worn in the left and right ears will then output audio from the corresponding channels, effectively avoiding sound field distortion caused by playing audio information from non-corresponding channels, thus improving user efficiency and experience.

[0135] Thirdly, this application provides an earphone assembly, including an earphone case and two earphones. The earphone case has a left earphone compartment and a right earphone compartment, which are used to accommodate the two earphones respectively.

[0136] The headphone assembly is used to configure the headphones placed in the left headphone compartment as the left channel and the headphones placed in the right headphone compartment as the right channel.

[0137] In the headphone assembly shown in this application, the user can freely insert the two earphones into the left and right earphone compartments respectively. The headphone assembly can configure the earphone inserted into the left earphone compartment as the left channel and the earphone inserted into the right earphone compartment as the right channel. When using the headphones, the user can directly wear the earphone inserted into the left earphone compartment in the left ear and the earphone inserted into the right earphone compartment in the right ear. The user can then listen to multi-channel audio normally, avoiding the sound field distortion problem caused by playing audio information from non-corresponding channels, which helps to improve the realism of the sound source and the audiovisual effect.

[0138] In one embodiment, the earphone case is used to send a first signal to the earphone inserted into the left earphone compartment and a second signal to the earphone inserted into the right earphone compartment.

[0139] The headphones can respond to a first signal and be configured as the left channel, and can also respond to a second signal and be configured as the right channel.

[0140] In the headphone channel control method described in this embodiment, the headphone case sends a first signal to the earphone placed in the left earphone compartment and a second signal to the earphone placed in the right earphone compartment, so that the earphones placed in the left and right earphone compartments are configured with matching channels. When using the headphones, the user can directly wear the earphone placed in the left earphone compartment in the left ear and the earphone placed in the right earphone compartment in the right ear. The earphones worn in the left and right ears will then output audio from the corresponding channels, which can effectively avoid sound field disorder caused by playing audio information from non-corresponding channels, and improve the user's efficiency and user experience.

[0141] In one embodiment, each earphone includes a housing and two charging terminals, which are exposed relative to the housing and spaced apart from each other.

[0142] The earphone case includes two left-side power supply terminals, two right-side power supply terminals, a storage module, and a voltage detection module. The two left-side power supply terminals protrude from the wall of the left earphone compartment and are spaced apart from each other, for contacting the two charging terminals of the earphones respectively. The two right-side power supply terminals protrude from the wall of the right earphone compartment and are spaced apart from each other, for contacting the two charging terminals of the earphones respectively. The storage module is used to store a preset voltage difference, and the voltage detection module is used to detect the voltage difference between the two left-side power supply terminals and the voltage difference between the two right-side power supply terminals.

[0143] When the voltage difference between the two left-side power supply terminals is equal to or greater than the preset voltage difference, the earphone box sends the first signal.

[0144] When the voltage difference between the two right-side power supply terminals is equal to or greater than the preset voltage difference, the earphone box sends a second signal.

[0145] It should be understood that when an earphone is inserted into the left earphone compartment, the two left-side power supply terminals come into contact with the two charging terminals of the earphone inserted into the left earphone compartment to conduct electricity, resulting in a voltage difference between the two left-side power supply terminals. Similarly, when an earphone is inserted into the right earphone compartment, the two right-side power supply terminals come into contact with the two charging terminals of the earphone inserted into the right earphone compartment to conduct electricity, resulting in a voltage difference between the two right-side power supply terminals. Therefore, the earphone case can determine whether earphones are inserted into the left and right earphone compartments by detecting the voltage difference between the two left-side power supply terminals and the two right-side power supply terminals.

[0146] In one embodiment, the earphone case includes a battery electrically connected to two left-side power supply terminals and two right-side power supply terminals. Each earphone includes a battery electrically connected to two charging terminals.

[0147] In one embodiment, the earphone is used to send a detection signal. The earphone case includes a left detection module and a right detection module. The left detection module corresponds to the left earphone compartment and is used to detect the detection signal. The right detection module corresponds to the right earphone compartment and is used to detect the detection signal.

[0148] When the left detection module detects the detection signal, the earphone box sends the first signal;

[0149] When the right-side detection module detects the detection signal, the earphone box sends a second signal.

[0150] In one embodiment, the earphone case includes a left contact terminal and a right contact terminal. The left contact terminal protrudes relative to the groove wall of the left earphone compartment for transmitting a first signal, and the right contact terminal protrudes relative to the groove wall of the right earphone compartment for transmitting a second signal.

[0151] Each earphone includes a contact terminal for contacting the left contact terminal to receive a first signal, and for contacting the right contact terminal to receive a second signal.

[0152] In one embodiment, the earphone is configured to detect whether it was previously configured as the left channel when receiving a first signal; if so, it remains in the left channel in response to the first signal; otherwise, it switches to the left channel in response to the first signal.

[0153] The headphones are also used to detect whether the previous channel was the right channel when receiving the second signal. If so, they remain in the right channel in response to the second signal; otherwise, they switch to the right channel in response to the second signal.

[0154] In the headphone assembly shown in this embodiment, the headphone first detects whether its channel type before configuration is the target channel type based on the signal sent by the headphone box, and then performs channel configuration based on the detection result. When the channel type of the headphone before configuration is consistent with the target channel type, the steps of configuring the headphone channel can be saved, which helps to simplify the process of the headphone channel configuration method.

[0155] In one embodiment, the headphones are configured to reset to the left channel upon receiving a first signal. The headphones are also configured to reset to the right channel upon receiving a second signal.

[0156] In the headphone assembly shown in this embodiment, the headphones are directly reset to the target channel type based on the signal sent by the headphone box, eliminating the need for channel detection and simplifying the headphone channel configuration process.

[0157] In one embodiment, the earphone case is used to detect whether the earphone placed in the left earphone compartment is in the left channel before configuration. If so, the channel configuration ends; otherwise, a channel switching signal is sent.

[0158] The earphone case also detects whether the earphone placed in the right earphone compartment is in the right channel before configuration. If so, the channel configuration ends; otherwise, a channel switching signal is sent.

[0159] The headphones can switch audio channels in response to a channel switching signal.

[0160] In the headphone assembly shown in this embodiment, the headphone case first detects whether the channel type of the headphone before configuration is the target channel type, and then performs channel configuration based on the detection result. When the channel type of the headphone before configuration is consistent with the target channel type, the channel configuration can be ended directly, saving the headphone from performing channel configuration steps and helping to simplify the process of headphone channel configuration.

[0161] In one embodiment, the earphone is configured to be in the left channel when the left earphone compartment is detected to be inserted, and also configured to be in the right channel when the right earphone compartment is detected to be inserted.

[0162] In the headphone assembly shown in this embodiment, the headphones themselves detect whether they are inserted into the left or right earphone compartment and automatically configure themselves to the matching audio channel based on the detection result. When using the headphones, the user can directly wear the earphone inserted into the left earphone compartment in the left ear and the earphone inserted into the right earphone compartment in the right ear. The earphones worn in the left and right ears will then output audio from the corresponding audio channel, effectively avoiding sound field distortion caused by playing audio information from non-corresponding channels, thus improving user efficiency and experience.

[0163] In one embodiment, two earpieces can be electrically connected to a terminal, which is used to identify the earpiece worn in the left ear and the earpiece worn in the right ear, send a third signal to the earpiece worn in the left ear, and send a fourth signal to the earpiece worn in the right ear.

[0164] The headphones can respond to a third signal and be configured as the left channel, and can also respond to a fourth signal and be configured as the right channel.

[0165] When using the headphones, users do not need to consciously distinguish between the left and right earpieces; they can freely wear the two earpieces in the left and right ears respectively. The terminal can identify the earpiece worn in the left and right ears, sending a third signal to the earpiece worn in the left ear and a fourth signal to the earpiece worn in the right ear. The two earpieces can automatically configure their audio channels according to the signals sent by the terminal to listen to multi-channel audio normally. This avoids the problem of sound field disorder caused by playing audio information in non-corresponding channels, which helps to improve usage efficiency and user experience.

[0166] In one embodiment, each earphone includes an information acquisition module for acquiring heartbeat propagation signals at the wearing position of the earphone.

[0167] The terminal compares the heartbeat propagation signals of the two earphones at their wearing positions to determine, within the same signal cycle, that the earphone with the earlier arrival time of the preset position of the heartbeat propagation signal at its wearing position is worn in the left ear, and the earphone with the later arrival time of the preset position of the heartbeat propagation signal at its wearing position is worn in the right ear.

[0168] It should be understood that the human heart is located on the left side of the body, and the path of the heartbeat from the heart to the left ear is shorter than the path to the right ear. Accordingly, if we compare the heartbeat signal at the left ear location with the heartbeat signal at the right ear location, we can see that at a preset position within the same signal cycle, the heartbeat signal at the left ear will precede the heartbeat signal at the right ear. This allows us to determine whether the earphone is worn on the left ear or the right ear.

[0169] When using the headphones, users do not need to consciously distinguish between the left and right earphones; they can freely wear the two earphones in the left and right ears respectively. The information acquisition modules of the two earphones respectively obtain the heartbeat transmission signal of the earphone wearing position. The terminal can determine which earphone is worn in the left ear and which is worn in the right ear based on the heartbeat transmission signal of the two earphone wearing positions. The two earphones can automatically configure the audio channels according to the signal sent by the terminal to listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information in the wrong channel, which helps to improve usage efficiency and user experience.

[0170] In one embodiment, the information acquisition module is a microphone or a voice pickup sensor.

[0171] In this embodiment, there is no need to add additional sensors to the earphones. The heartbeat transmission signal at the location of the earphones can be obtained directly using the earphones' microphone or voice pickup sensor to determine which earphone is worn in the left ear and which is worn in the right ear, which helps to simplify the earphone structure.

[0172] In one embodiment, the information acquisition module is a biometric sensor.

[0173] In one embodiment, the headphones include an earbud, an ear stem, and an information acquisition module. The ear stem is fixedly connected to the earbud, and the information acquisition module is housed inside the earbud or the ear stem to acquire gravitational acceleration information of the headphones during wear.

[0174] The terminal uses the gravitational acceleration information of the two earphones during the wearing process to determine the direction of the earphones' wearing position relative to the direction of gravity, and determines that the earphone whose wearing position is deflected clockwise relative to the direction of gravity is worn in the left ear, and the earphone whose wearing position is deflected counterclockwise relative to the direction of gravity is worn in the right ear.

[0175] It should be understood that, due to the inclusion of the earpiece, the structure of headphones has certain limitations, meaning they have limited points. This means that when a user wears headphones, they cannot rotate 360° around the ear canal; they can only rotate within a certain range. Since the user's left and right ears are mirror-symmetrically positioned, when the user puts the two headphones on their left and right ears respectively, they will rotate the two headphones in opposite directions until both are in the correct position. At this time, the gravitational acceleration information of the headphones will change. Therefore, the difference in gravitational acceleration information during the wearing process can be used to distinguish between the headphones worn on the left and right ears.

[0176] When using the headphones, users do not need to consciously distinguish between the left and right earbuds; they can freely wear the two earbuds in the left and right ears respectively. The information acquisition modules of each earbud obtain the gravitational acceleration information during the wearing process. The terminal can determine which earbud is worn in the left and right ears based on the two gravitational acceleration information during the wearing process. The two earbuds can automatically configure the audio channels according to the signals sent by the terminal to listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information in the wrong channel, which helps to improve usage efficiency and user experience.

[0177] In one embodiment, the information acquisition module is a gravity acceleration sensor, a gyroscope, or an electronic compass.

[0178] In one embodiment, the earphone is configured as the left channel when it is detected that it is worn in the left ear, and as the right channel when it is detected that it is worn in the right ear.

[0179] When using headphones, users do not need to distinguish between the left and right earphones. They can wear the two earphones on the left and right earphones respectively. The headphones can detect whether they are worn on the left or right ear and automatically configure the corresponding audio channel to listen to multi-channel audio normally. This avoids the problem of sound field disorder caused by playing audio information on the wrong channel, which helps to improve usage efficiency and user experience.

[0180] In one embodiment, each earphone includes an in-ear detection module for detecting whether the earphone is in-ear.

[0181] In one implementation, the earphone is used to detect whether it was previously configured as the left channel when it is detected that it is worn on the left ear; if so, it remains in the left channel; otherwise, it switches to the left channel.

[0182] The headphones are also used to detect whether the previous setting was the right channel when the right ear is detected. If so, they remain on the right channel; otherwise, they switch to the right channel.

[0183] In the headphone assembly shown in this embodiment, the headphone first detects whether its channel type before configuration is the target channel type, and then performs channel configuration based on the detection result. When the channel type of the headphone before configuration is consistent with the target channel type, the steps of configuring the headphone channel can be saved, which helps to simplify the process of configuring the headphone channel.

[0184] Fourthly, this application provides a computer-readable storage medium for storing a headphone channel configuration program, which, when executed, implements any of the headphone channel configuration methods described above. Attached Figure Description

[0216] The embodiments of this application are described below with reference to the accompanying drawings.

[0217] Please see Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of an earphone assembly 100 provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the structure of the headphone assembly 100 in another state.

[0218] This application provides an earphone assembly 100, including an earphone 10 and an earphone case 20. The earphone 10 includes two earpieces 11, which are housed inside the earphone case 20. The two earpieces 11 are communicatively connected.

[0219] Understandably, based on the wearing method, the earphone 10 can be an in-ear earphone, a semi-in-ear earphone, an ear-hook earphone, a neckband earphone, or a headphone, etc. Based on the method by which the earphone 10 establishes a communication connection with the terminal, the earphone 10 can be a wireless earphone that establishes a communication connection with the terminal via Bluetooth, or the earphone 10 can be a wired earphone that establishes a communication connection with the terminal via a wire.

[0220] The terminal can be an electronic device such as a smartphone, tablet, PDA, personal digital assistant (PDA), mobile internet device (MID), or smart wearable device. The headset 10 can establish a communication connection with the terminal to handle audio services such as media and calls, or other data services. For example, the audio services may include playing music, recordings, audio from video files, background music in games, and call notification sounds for the user; it may also include playing the terminal's voice data or collecting the user's voice data and sending it to the terminal in call scenarios such as phone calls, WeChat voice messages, audio calls, video calls, games, and voice assistants.

[0221] This application uses a true wireless stereo (TWS) earphone as an example for illustration. A stereo earphone is one that plays audio with a left and right channel. When a user uses earphone 10, one earphone 11 is worn in the user's left ear to play the left channel audio, and the other earphone 11 is worn in the user's right ear to play the right channel audio, thus achieving stereo playback from earphone 10.

[0222] In this embodiment, the two earphones 11 have the same structure and shape to reduce the production and manufacturing cost of the earphones 10. When using the earphones 10, the user does not need to distinguish which earphone 11 is suitable for the left ear and which earphone 11 is suitable for the right ear. The user can wear the two earphones 11 on either the left or right ear to avoid the discomfort caused by the earphones 11 not fitting the user's ear shape due to wearing the wrong earphones 11.

[0223] The earphone case 20 can be an earphone charging case, smartwatch, smart bracelet, or smartphone, or any other product that can hold the earphones 10. This embodiment uses an earphone charging case as an example for illustration.

[0224] The earphone case 20 includes a case body 21, a lid 22, and an earphone holder 23. The lid 22 can be closed onto the case body 21, and the earphone holder 23 is located inside the case body 21 for holding the earphones 10. In this embodiment, the lid 22 and the case body 21 are independent structural components. The lid 22 is detachably installed on the case body 21. At this time, the lid 22 closes the case body 21 and forms a closed box-like body with the case body 21 (e.g., ...). Figure 1 (As shown), to store and protect the headphones 10. It should be understood that the shape of the box is not limited to... Figure 1 The oval shape shown can also be rectangular, rectangular, or other irregular shapes. Furthermore, the lid 22 can also be removed from the box body 21 (e.g., Figure 2 As shown), the lid 22 can also be opened relative to the body 21 to allow the earphone 10 to be placed into or removed from the earphone case 20.

[0225] In some other embodiments, the lid 22 can be opened and closed and installed on the box body 21, or the lid 22 can be slidably installed on the box body 21, or the lid 22 can be installed on the box body 21 by a hinge structure, or the lid 22 can be installed on the box body 21 by magnetic attraction. This application does not specifically limit the assembly relationship between the lid 22 and the box body 21.

[0226] Please see Figure 3 , Figure 3 yes Figure 2 The diagram shows the assembly structure of the headphone case 20 and the headphone base 23 in the headphone assembly 100.

[0227] The earphone holder 23 is fixedly connected to the housing 21 and forms a receiving cavity (not shown in the figure) with the housing 21. The earphone holder 23 has a left earphone compartment 231 and a right earphone compartment 232. The openings of the left earphone compartment 231 and the right earphone compartment 232 are arranged alternately on the top surface of the earphone holder 23 (not shown in the figure), and the recessed direction of the left earphone compartment 231 and the right earphone compartment 232 is from the top surface of the earphone holder 23 towards the bottom surface (not shown in the figure). That is, the top surface of the earphone holder 23 is partially recessed to form the spaced-apart left earphone compartment 231 and right earphone compartment 232.

[0228] It should be noted that the directional terms such as "top" and "bottom" used in the headphone holder 23 of this application embodiment are mainly based on the fact that the headphone holder 23 is attached to the device. Figure 2 The orientation of the display is described with the direction facing the lid 22 as the top and the direction away from the lid 22 as the bottom. This does not limit the orientation of the headphone holder 23 in actual application scenarios.

[0229] In some other embodiments, the left earphone compartment 231 and the right earphone compartment 232 may not be provided on the earphone base 23, but on the box body 21 or other components of the earphone box 20. The present application does not make specific limitations in this regard, as long as the earphone box 20 is provided with the left earphone compartment 231 and the right earphone compartment 232.

[0230] Among them, the left earphone compartment 231 and the right earphone compartment 232 have the same structure and shape, and are adapted to the structure and shape of the earphone 11, for respectively accommodating the two earphones 11 of the earphone 10. Exemplarily, the left earphone compartment 231 includes a first part (not labeled in the figure) and a second part (not labeled in the figure) communicating with the first part. The first part is generally in the shape of a cylindrical hole and is adapted to the structure and shape of the earplug of the earphone 11, so as to facilitate accommodating the earplug of the earphone 11. The second part is generally in the shape of a long strip hole and is adapted to the structure and shape of the ear rod of the earphone 11, so as to facilitate accommodating the ear rod of the earphone 11.

[0231] In this embodiment, the earphone box 20 is provided with a first identifier 201 and a second identifier 202, and both the first identifier 201 and the second identifier 202 are located on the top surface of the earphone base 23. Specifically, the first identifier 201 is placed at the periphery of the opening of the left earphone compartment 231 for identifying the left earphone compartment 231. The second identifier 202 is placed at the periphery of the right earphone compartment 232 for identifying the right earphone compartment 232. Among them, the first identifier 201 is the English letter "L" (representing the English word "left") to identify that the channel type of the earphone 11 accommodated in the left earphone compartment 231 is the left channel. The second identifier 202 is "R" (representing the English word "right") to identify that the channel type of the earphone 11 accommodated in the right earphone compartment 232 is the right channel.

[0232] In some other embodiments, the first identifier 201 may be the Chinese character "left", and / or the second identifier 202 may be the Chinese character "right", or the earphone base 23 is only provided with the first identifier 201 or the second identifier 202, as long as the left earphone compartment 231 and the right earphone compartment 232 can be distinguished, or the earphone box 20 is not provided with the first identifier 201 and the second identifier 202. By default, when the box cover 22 is opened relative to the box body 21, the earphone compartment on the user's left hand side is the left earphone compartment 231, and the earphone compartment on the user's right hand side is the right earphone compartment 232. The present application does not make specific limitations on the distinguishing and identifying methods of the left earphone compartment 231 and the right earphone compartment 232.

[0233] In some embodiments, the earphone case 20 may further include a retaining holder (not shown), located inside the case cover 22. Specifically, the retaining holder is fixed to the case cover 22. The retaining holder has a left retaining compartment and a right retaining compartment. The left retaining compartment matches the left earphone compartment 231, and the right retaining compartment matches the right earphone compartment 232, so as to facilitate the storage of two earphones 11, ensure that the two earphones 11 do not easily shake inside the earphone case 20, reduce the collision between the two earphones 11 and the earphone case 20, and improve the service life.

[0234] Please see Figure 3 and Figure 4 , Figure 4 yes Figure 2 The diagram shows the modular structure of the headphone box 20 in the headphone assembly 100.

[0235] The earphone case 20 also includes a controller 24, a battery 25, a power supply terminal 26, and a charging interface 27. The controller 24 and battery 25 are both housed within a receiving cavity. The controller 24 is electrically connected to the battery 25 to control the battery 25 to charge the two earphones 11. The power supply terminal 26 is electrically connected to the battery 25 and is used to contact the earphones 11 to conduct electricity, thereby charging the earphones 11. The power supply terminal 26 can be a connector such as a spring pin, spring contact, conductive block, conductive patch, conductive sheet, pin, plug, contact pad, jack, or socket.

[0236] In this embodiment, there are four power supply terminals 26. Two of them are left power supply terminals 26a, and the other two are right power supply terminals 26b.

[0237] Two left-side power supply terminals 26a are exposed relative to the wall of the left earphone compartment 231 and are spaced apart from each other. Specifically, the two left-side power supply terminals 26a are exposed relative to the bottom wall of the left earphone compartment 231. The two left-side power supply terminals 26a are exposed relative to the bottom wall of the second part of the left earphone compartment 231. The two left-side power supply terminals 26a serve as positive and negative terminals, respectively, and are used to contact the earphone 11 inserted into the left earphone compartment 231 to conduct electricity, thereby establishing an electrical connection between the battery 25 and the earphone 11 inserted into the left earphone compartment 231, so that the battery 25 can charge the earphone 11 inserted into the left earphone compartment 231.

[0238] In some other embodiments, the two left-side power supply terminals 26a may also be exposed relative to the bottom wall of the slot in the first part of the left earphone compartment 231, or the two left-side power supply terminals 26a may also be exposed relative to the side wall of the slot in the left earphone compartment 231, or one left-side power supply terminal 26a may be exposed relative to the bottom wall of the slot in the left earphone compartment 231 and the other left-side power supply terminal 26a may be exposed relative to the side wall of the slot in the left earphone compartment 231.

[0239] Two right-side power supply terminals 26b are exposed relative to the wall of the right earphone compartment 232 and are spaced apart from each other. Specifically, the two right-side power supply terminals 26b are exposed relative to the bottom wall of the right earphone compartment 232. Specifically, the two right-side power supply terminals 26b are exposed relative to the bottom wall of the second part of the right earphone compartment 232. The two right-side power supply terminals 26b serve as positive and negative terminals, respectively, to contact the earphone 11 inserted into the right earphone compartment 232 to provide power, thereby establishing an electrical connection between the battery 25 and the earphone 11 inserted into the right earphone compartment 232, so that the battery 25 can charge the earphone 11 inserted into the right earphone compartment 232.

[0240] In some other embodiments, the two right-side power supply terminals 26b may also be exposed relative to the bottom wall of the slot in the first part of the right earphone compartment 232, or the two right-side power supply terminals 26b may also be exposed relative to the side wall of the slot in the right earphone compartment 232, or one right-side power supply terminal 26b may be exposed relative to the bottom wall of the slot in the right earphone compartment 232, and the other right-side power supply terminal 26b may be exposed relative to the side wall of the slot in the right earphone compartment 232.

[0241] The charging port 27 is electrically connected to the battery 25 and is exposed relative to the housing 21. For example, one end of a charging cable adapted to the charging port 27 can be inserted into the charging port 27, and the other end can be inserted into the power supply interface of an external power source, thus establishing an electrical connection between the battery 25 and an external power source for charging. The charging port 27 can be a USB port, a Mini USB port, a Type-A port, a Type-B port, or a Type-C port.

[0242] In addition, the earphone case 20 includes an insertion detection module 30, which detects whether earphones 11 are placed in the left earphone compartment 231 and the right earphone compartment 232, respectively. When the insertion detection module 30 detects that earphones 11 are placed in the left earphone compartment 231, the battery 25 of the earphone case 20 charges the earphones 11 placed in the left earphone compartment 231 to extend the battery life of the earphones 11 placed in the left earphone compartment 231. Similarly, when the insertion detection module 30 detects that earphones 11 are placed in the right earphone compartment 232, the battery 25 of the earphone case 20 charges the earphones 11 placed in the right earphone compartment 232 to extend the battery life of the earphones 11 placed in the right earphone compartment 232.

[0243] It should be understood that the case insertion detection module 30 can also simultaneously detect whether earphones 11 are inserted into the left earphone compartment 231 and the right earphone compartment 232. When the case insertion detection module 30 detects that earphones 11 are inserted into both the left earphone compartment 231 and the right earphone compartment 232, that is, when the case insertion detection module 30 determines that the two earphones 11 are inserted into the left earphone compartment 231 and the right earphone compartment 232 respectively, the battery 25 of the earphone case 20 is used to charge the earphones 11 inserted into the left earphone compartment 231 and the earphones 11 inserted into the right earphone compartment 232, so as to extend the battery life of the earphones 10.

[0244] In this embodiment, the in-box detection module 30 includes a controller 24 and a power supply terminal 26, with the power supply terminal 26 electrically connected to the controller 24. The controller 24 includes a storage unit 241, a voltage detection unit 242, and a processing unit 243. The storage unit 241 stores a preset voltage difference ΔV0 and a preset time period ΔT. The voltage detection unit 242 is electrically connected to two left-side power supply terminals 26a to detect a first voltage difference ΔV1. The voltage detection unit 242 is also electrically connected to two right-side power supply terminals 26b to detect a second voltage difference ΔV2. The first voltage difference ΔV1 is the voltage difference between the two left-side power supply terminals 26a, and the second voltage difference ΔV2 is the voltage difference between the two right-side power supply terminals 26b. The processing unit 243 is electrically connected to the voltage detection unit 242 and the storage unit 241 to receive the first voltage difference ΔV1 and the second voltage difference ΔV2 detected by the voltage detection unit 242, and compare the first voltage difference ΔV1 and the second voltage difference ΔV2 with the preset voltage difference ΔV0, and determine whether the two earphones 11 are put into the box based on the comparison result.

[0245] It should be noted that the controller 24 can be the processor of the headphone case 20. In some other embodiments, the storage unit 241 and the voltage detection unit 242 can also be part of other electronic components in the headphone case 20, or the storage unit 241 and the voltage detection unit 242 can be separate devices in the headphone case 20. This application does not specifically limit them in this regard.

[0246] It should be understood that when earphone 11 is inserted into the left earphone compartment 231, the two left-side power supply terminals 26a come into contact with the earphone 11 inserted into the left earphone compartment 231 to conduct electricity, and there will be a voltage difference between the two left-side power supply terminals 26a. Similarly, when earphone 11 is inserted into the right earphone compartment 232, the two right-side power supply terminals 26b come into contact with the earphone 11 inserted into the right earphone compartment 232 to conduct electricity, and there will be a voltage difference between the two right-side power supply terminals 26b. Therefore, it is possible to determine whether the two earphones 11 are in the case by detecting the voltage difference between the two power supply terminals 26a.

[0247] In some other embodiments, the insertion detection module 30 may also use a pressure sensor, a light detection sensor (such as an infrared light detector) or a distance sensor to determine whether the earphone 11 is placed in the left earphone compartment 231 or the right earphone compartment 232. This application does not specifically limit the detection method of the insertion detection module 30.

[0248] Specifically, when the case lid 22 is opened relative to the case body 21, the earphone insertion detection module 30 uses a polling communication method to detect whether earphones 11 are placed in the left earphone compartment 231 and the right earphone compartment 232 respectively. When the first voltage difference ΔV1 is equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that earphones 11 are placed in the left earphone compartment 231 and controls the battery 25 to charge the earphones 11 placed in the left earphone compartment 231. When the first voltage difference ΔV1 is less than the preset voltage difference ΔV0, the processing unit 243 determines that earphones 11 are not placed in the left earphone compartment 231. After a preset time period ΔT, the voltage detection unit 242 re-detects the first voltage difference ΔV1 until the processing unit 243 determines that earphones 11 are placed in the left earphone compartment 231.

[0249] When the second voltage difference ΔV2 is equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that the right earphone 11 is inserted into the right earphone compartment 232 and controls the battery 25 to charge the earphone 11 inserted into the right earphone compartment 232. When the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the right earphone 11 is not inserted into the right earphone compartment 232. After a preset time period ΔT, the voltage detection unit 242 re-detects the second voltage difference ΔV2 until the processing unit 243 determines that the right earphone 11 is inserted into the right earphone compartment 232.

[0250] Understandably, the earphone case detection module 30 can also use a polling communication method to simultaneously detect whether earphones 11 are inserted into the left earphone compartment 231 and the right earphone compartment 232. When the first voltage difference ΔV1 and the second voltage difference ΔV2 are both equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that earphones 11 are inserted into both the left earphone compartment 231 and the right earphone compartment 232, and controls the battery 25 to charge the earphones 11 inserted into both the left earphone compartment 231 and the right earphone compartment 232 simultaneously. In other words, the battery 25 of the earphone case 20 can only charge the earphones 11 inserted into both the left earphone compartment 231 and the right earphone compartment 232 when and only when earphones 11 are inserted into both the left earphone compartment 231 and the right earphone compartment 232.

[0251] When the first voltage difference ΔV1 and / or the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both equipped with earphones 11. After a preset time period ΔT, the voltage detection unit 242 re-detects the first voltage difference ΔV1 and the second voltage difference ΔV2 until the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are both equipped with earphones 11. That is to say, when the first voltage difference ΔV1 is less than the preset voltage difference ΔV0 and the second voltage difference ΔV2 is equal to or greater than the preset voltage difference ΔV0, or when the first voltage difference ΔV1 is equal to or greater than the preset voltage difference ΔV0 and the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, or when the first voltage difference ΔV1 is less than the preset voltage difference ΔV0 and the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both equipped with earphones 11.

[0252] Furthermore, the earphone assembly 100 is used to configure the earphone 11 inserted into the left earphone compartment 231 as the left channel and the earphone 11 inserted into the right earphone compartment 232 as the right channel. In this embodiment, the earphone case 20 is also used to send a first signal to the earphone 11 inserted into the left earphone compartment 231 and a second signal to the earphone 11 inserted into the right earphone compartment 232. The first signal is used to indicate that the earphone 11 inserted into the left earphone compartment 231 is configured as the left channel, and the second signal is used to indicate that the earphone 11 inserted into the right earphone compartment 232 is configured as the right channel.

[0253] Specifically, the earphone case 20 also includes a contact terminal 28, which is electrically connected to the controller 24 and is used to contact the earphone 11 to conduct electricity, thereby realizing the communication connection between the controller 24 and the earphone 11. The contact terminal 28 can be a spring pin, spring sheet, conductive block, conductive patch, conductive sheet, pin, plug, contact pad, socket or other connector.

[0254] In this embodiment, there are two contact terminals 28, namely a left contact terminal 28a and a right contact terminal 28b. The left contact terminal 28a is exposed relative to the groove wall of the left earphone compartment 231. Specifically, the left contact terminal 28a is exposed relative to the groove side wall of the left earphone compartment 231. Specifically, the left contact terminal 28a is exposed relative to the groove side wall of the first portion of the left earphone compartment 231. The left contact terminal 28a is used to contact the earphone 11 inserted into the left earphone compartment 231 to provide power, thereby establishing a communication connection between the controller 24 and the earphone 11 inserted into the left earphone compartment 231. In some other embodiments, the left contact terminal 28a may also be exposed relative to the groove side wall of the second portion of the left earphone compartment 231, or the left contact terminal 28a may also be exposed relative to the groove bottom wall of the left earphone compartment 231.

[0255] The left contact terminal 28a is electrically connected to the processing unit 243 of the controller 24 to send a first signal. When the processing unit 243 confirms that the earphone 11 is inserted into the left earphone compartment 231, the processing unit 243 sends the first signal to the earphone 11 inserted into the left earphone compartment 231 through the left contact terminal 28a. The first signal is used to indicate that the earphone 11 inserted into the left earphone compartment 231 is configured as the left channel.

[0256] The right-side contact terminal 28b is exposed relative to the groove wall of the right earphone compartment 232. Specifically, the right-side contact terminal 28b is exposed relative to the groove side wall of the right earphone compartment 232. Specifically, the right-side contact terminal 28b is exposed relative to the groove side wall of the first portion of the right earphone compartment 232. The right-side contact terminal 28b is used to abut against the earphone 11 inserted into the right earphone compartment 232 to energize it, thereby establishing a communication connection between the controller 24 and the earphone 11 inserted into the right earphone compartment 232. In some other embodiments, the right-side contact terminal 28b may also be exposed relative to the groove side wall of the second portion of the right earphone compartment 232, or the right-side contact terminal 28b may also be exposed relative to the groove bottom wall of the right earphone compartment 232.

[0257] The right contact terminal 28b is electrically connected to the processing unit 243 of the controller 24 to send a second signal. Specifically, when the processing unit 243 confirms that the earphone 11 is inserted into the right earphone compartment 232, the processing unit 243 sends a second signal to the earphone 11 inserted into the right earphone compartment 232 via the right contact terminal 28b. The second signal instructs the earphone 11 inserted into the right earphone compartment 232 to configure the channel type to the right channel.

[0258] In some embodiments, the processing unit 243 sends the first signal and the second signal only when it confirms that both earphones 11 are inserted into the case, that is, when the processing unit 243 confirms that both the left earphone case 231 and the right earphone case 232 are filled with earphones 11. Specifically, when the processing unit 243 confirms that both the left earphone case 231 and the right earphone case 232 are filled with earphones 11, the processing unit 243 sends the first signal to the earphone 11 placed in the left earphone case 231 through the left contact terminal 28a, and sends the second signal to the earphone 11 placed in the right earphone case 232 through the right contact terminal 28b, so as to realize the channel configuration of the earphones 11 placed in the left earphone case 231 and the right earphone case 232.

[0259] When processing unit 243 confirms that the left earphone compartment 231 and / or the right earphone compartment 232 are not inhabited with earphone 11, processing unit 243 neither sends the first signal nor the second signal, that is, it does not configure the channel type of earphone 11. In other words, when processing unit 243 confirms that the left earphone compartment 231 is inhabited with earphone 11 and the right earphone compartment 232 is not inhabited, or when processing unit 243 confirms that the left earphone compartment 231 is not inhabited with earphone 11 and the right earphone compartment 232 is inhabited, or when processing unit 243 confirms that the left earphone compartment 231 is not inhabited with earphone 11 and the right earphone compartment 232 is not inhabited, processing unit 243 does not send the first signal or the second signal, that is, it does not configure the channel type of earphone 11.

[0260] It should be noted that in this embodiment, the contact terminal 28 and the power supply terminal 26 of the earphone case 20 are relatively independent terminals. That is, the contact terminal 28 is used to abut against the earphone 11 for communication connection, and the power supply terminal 26 is used to abut against the earphone 11 for charging. In some other embodiments, the earphone case 20 may only include the power supply terminal 26 and not the contact terminal 28. In this case, the power supply terminal 26 can integrate the function of the contact terminal 28 to realize the communication connection between the controller 24 and the earphone 11. That is, the power supply terminal 26 abutting against the earphone 11 can both charge the earphone 11 and communicate with it. In other words, the processing unit 243 can also send a first signal to the earphone 11 placed in the left earphone compartment 231 through the left power supply terminal 26a, and can also send a second signal to the earphone 11 placed in the right earphone compartment 232 through the right power supply terminal 26b.

[0261] Specifically, when processing unit 243 confirms that earphone 11 is inserted into left earphone compartment 231, processing unit 243 first sends a first signal to earphone 11 inserted into left earphone compartment 231 through left power supply terminal 26a, and then controls battery 25 to charge earphone 11 inserted into left earphone compartment 231 through left power supply terminal 26a. When processing unit 243 confirms that earphone 11 is inserted into right earphone compartment 232, processing unit 243 first sends a second signal to earphone 11 inserted into right earphone compartment 232 through right power supply terminal 26b, and then controls battery 25 to charge earphone 11 inserted into right earphone compartment 232 through right power supply terminal 26b.

[0262] In some embodiments, if and only when the processing unit 243 confirms that both earphones 11 are in the case, that is, when the processing unit 243 confirms that both the left earphone case 231 and the right earphone case 232 are filled with earphones 11, the processing unit 243 of the controller 24 first sends a first signal to the earphone 11 placed in the left earphone case 231 through the left power supply terminal 26a, and sends a second signal to the earphone 11 placed in the right earphone case 232 through the right power supply terminal 26b. Then, the battery 25 is controlled to charge the earphone 11 placed in the left earphone case 231 through the left power supply terminal 26a, and to charge the earphone 11 placed in the right earphone case 232 through the right power supply terminal 26b.

[0263] In addition, the headphone case 20 may also include a display screen 29, which is electrically connected to the controller 24 and protrudes from the top surface of the headphone holder 23 for easy viewing. The display screen 29 is used to display information related to the headphone case 20 and the headphones 10 housed inside the headphone case 20, such as the battery level of the headphone case 20, the battery level of the two headphones 11, the channel type, and the charging status. In some other embodiments, the headphone case 20 may include indicator lights to indicate the battery level of the battery 25 and related information about the headphones 10 housed inside the headphone case 20, such as the battery level, channel type, and charging status of the headphones 11.

[0264] Please see Figure 5 and Figure 6 , Figure 5 yes Figure 2 The diagram shows the structure of the earphone 11 in the earphone assembly 100. Figure 6 yes Figure 5 The diagram shows the module structure of the earphone 11 and the terminal 200.

[0265] The headset 11 includes a housing 12, a transceiver 13, a controller 14, an audio player 15, and a microphone 16. The transceiver 13, controller 14, audio player 15, and microphone 16 are all housed inside the housing 12. The transceiver 13 is used for wireless communication with the terminal 200 to enable information interaction with the terminal 200. For example, the transceiver 13 is Bluetooth. The controller 14 is electrically connected to the transceiver 13 and the audio player 15 to receive audio signals sent by the terminal 200 via the transceiver 13, process the audio signals, and control the audio player 15 to play audio. For example, the audio player 15 is a speaker or loudspeaker. The microphone 16 is electrically connected to the controller 14 to collect the user's voice. For example, the microphone 16 is a microphone or a voice pick-up sensor (VPU sensor). The controller 14 is also used to convert the voice picked up by the microphone 16 into an audio signal, and send the converted audio signal to the terminal 200 through the transceiver 13.

[0266] The housing 12 includes an earplug 121 and an ear stem 122, with the earplug 121 fixedly connected to the ear stem 122. The transceiver 13, controller 14, audio player 15, and microphone 16 can all be housed inside the earplug 121. When the user wears the headphones 10, the ear stem 122 protrudes relative to the user's ear, and at least a portion of the earplug 121 extends into the user's ear canal. This not only improves the wearing stability of the headphones 11 but also prevents audio leakage from the audio player 15, improving audio quality and user privacy.

[0267] In addition, the earphone 11 also includes an in-ear detection module 40, which is housed inside the earbud 121 and electrically connected to the controller 14 for detecting whether the earphone is in the ear. The controller 14 is also used to determine whether the earphone 11 is in the ear based on the detection result of the in-ear detection module 40, and to control the audio player 15 to play audio. When the controller 14 determines that the earphone 11 is in the ear, it controls the audio player 15 to play audio. For example, the in-ear detection module 40 is a proximity sensor, which is used to detect whether there is an object near the earphone 11, and the controller 14 determines whether the earphone 11 is being worn by the user based on the detection result of the in-ear detection module 40. In some other embodiments, the in-ear detection module 40 may also be a proximity light sensor.

[0268] In this embodiment, the earphone 11 also includes a battery 17 and a charging terminal 18. The battery 17 can be housed inside the ear stem 122 and is electrically connected to the controller 14. The battery 17 is used to charge under the control of the controller 14, or to power functional devices such as the transceiver 13, audio player 15, and microphone 16 under the control of the controller 14.

[0269] Charging terminal 18 is electrically connected to battery 17 and protrudes relative to housing 12 to contact an external power source for charging. For example, earphone 11 is inserted into left earphone compartment 231 or right earphone compartment 232 (e.g., ...). Figure 3 When (as shown), the charging terminal 18 can abut against the power supply terminal 26 of the earphone case 20 to conduct electricity, so as to enable the battery 25 of the earphone case 20 to charge the battery 17 of the earphone 11. The charging terminal 18 can be a connector such as a spring pin, spring sheet, conductive block, conductive patch, conductive sheet, pin, plug, contact pad, socket or socket.

[0270] There are two charging terminals 18. The two charging terminals 18 are exposed relative to the earpiece 122 and are spaced apart from each other. The two charging terminals 18 can serve as positive and negative terminals respectively, for connection to the two left-side power supply terminals 26a or the two right-side power supply terminals 26b (e.g., ...). Figure 3(As shown) Abuts against the earphone 11 to provide power, enabling the battery 25 of the earphone case 20 to charge the battery 17 of the earphone 11. In some other embodiments, the two charging terminals 18 may also be exposed relative to the earbud 121 of the housing 12, or one charging terminal 18 may be exposed relative to the ear stem 122 of the housing 12, and the other charging terminal 18 may be exposed relative to the earbud 121 of the housing 12. This application does not specifically limit the position of the two charging terminals 18.

[0271] In some embodiments, the earphone 11 may include a battery management module 70, which is electrically connected between the battery 17 and the charging terminal 18 to establish an electrical connection between the charging terminal 18 and the battery 17. The battery management module 70 may include a charging circuit, a voltage drop regulation circuit, a protection circuit, and a power measurement circuit. The charging circuit is electrically connected to the charging terminal 18 and can receive electrical signals from an external power source through the charging terminal 18. The voltage drop regulation circuit is electrically connected to the charging circuit and the battery 17, transforming the electrical signals input from the charging circuit and outputting them to the battery 17 to complete charging. It can also transform the electrical signals output from the battery 17 and output them to other functional components of the earphone 11 to power these components. The protection circuit can be used to prevent overcharging, over-discharging, short circuits, or overcurrent of the battery 17. Additionally, the battery management module 70 can also be used to monitor parameters such as the battery 17 capacity, battery cycle count, and battery health status (leakage current, impedance). In some other embodiments, the earphone 11 may also include a wireless charging coil electrically connected to the battery 17 to enable wireless charging of the battery 17.

[0272] In addition, the earphone 11 also includes a contact terminal 19. The contact terminal 19 is electrically connected to the controller 14 and is exposed relative to the housing 12. Specifically, the contact terminal 19 is exposed relative to the earbud 121 of the housing 12. The contact terminal 19 is used for electrical connection with external devices, enabling communication between the controller 14 of the earphone 11 and external devices. The contact terminal 19 can be a spring pin, spring contact, conductive block, conductive patch, conductive sheet, pin, plug, contact pad, jack, or socket, etc.

[0273] Specifically, the contact terminal 19 of the earphone 11 is used to abut against the contact terminal 28 to energize, thereby realizing the communication connection between the controller 14 of the earphone 11 and the controller 24 of the earphone case 20. The contact terminal 19 is used to abut against the left contact terminal 28a to energize and receive a first signal, and also to abut against the right contact terminal 28b to receive a second signal.

[0274] It should be noted that in this embodiment, the contact terminal 19 and the charging terminal 18 of the earphone 11 are relatively independent terminals. That is, the contact terminal 19 is used to abut against the contact terminal 28 of the earphone case 20 to realize the communication connection between the controller 14 of the earphone 11 and the controller 24 of the earphone case 20, and the charging terminal 18 is used to abut against the power supply terminal 26 of the earphone case 20 to realize the charging of the battery 25 of the earphone case 20 to the battery 17 of the earphone 11.

[0275] In some other embodiments, the earphone 11 may include only the charging terminal 18, omitting the contact terminal 19. In this case, the charging terminal 18 can integrate both charging and communication connection with the earphone case 20, simplifying the structure of the earphone 11. That is, the charging terminal 18, when abutting against the power supply terminal 26, can both charge the battery 17 of the earphone 11 and communicate with the controller 24 of the earphone case 20. Furthermore, the earphone 11 can also receive a first signal or a second signal through the charging terminal 18.

[0276] In this embodiment, the earphone 11 can be configured as the left channel in response to a first signal, and can also be configured as the right channel in response to a second signal. It should be noted that, in this application, "configured as the left channel" means that the channel type of the earphone 11 is configured as the left channel, and the relevant descriptions in the following text shall be understood in the same way.

[0277] The controller 14 of the headphones 11 includes a storage module 141, a processing module 142, and a channel configuration module 143. The storage module 141 stores the channel type of the headphones 11 before configuration. It should be understood that the channel type of the headphones 11 does not change from when they are inserted into the case until channel configuration is performed. Therefore, the channel type of the headphones 11 before configuration can also refer to the channel type of the headphones 11 before they are inserted into the case. The processing module 142 is electrically connected to the contact terminal 19 and the storage module 141. The processing module 142 receives a first signal or a second signal through the contact terminal 19, obtains the target channel type of the headphones 11 based on the first signal or the second signal, and determines whether the channel type of the headphones 11 before configuration is consistent with the target channel type.

[0278] The channel configuration module 143 is electrically connected to the processing module 142 and the audio player 15. The channel configuration module 143 receives the judgment result from the processing module 142 and configures the channel type of the headphones 11 accordingly, so that the audio player 15 can play audio of the corresponding channel type when the headphones 11 are used. When the channel type of the headphones 11 matches the target channel type, the channel configuration module 143 keeps the channel type of the headphones 11 unchanged; when the channel type of the headphones 11 does not match the target channel type, the channel configuration module 143 switches the channel type of the headphones 11, for example, switching from the left channel to the right channel, or vice versa. For example, the channel configuration module 143 can be an audio circuit.

[0279] When the earphone 11 is inserted into the left earphone compartment 231, the contact terminal 19 can abut against the left contact terminal 28a to conduct electricity, thus establishing a communication connection between the earphone 11 and the controller 24 of the earphone case 20. At this time, the earphone 11 can receive a first signal through the contact terminal 19 to detect whether it was in the left channel before configuration. If so, it remains in the left channel in response to the first signal. If not, it switches to the left channel in response to the first signal.

[0280] Specifically, the processing module 142 of the controller 14 receives a first signal through the contact terminal 19, determines the target channel type of the headphones 11 as the left channel based on the first signal, and determines whether the channel type of the headphones 11 before configuration is consistent with the target channel type, that is, whether the channel type of the headphones 11 before configuration is the left channel. The channel configuration module 143 obtains the judgment result of the processing module 142 and configures the channel type of the headphones 11 according to the judgment result.

[0281] When the channel type of the headphones 11 before configuration matches the target channel type, i.e., the channel type of the headphones 11 before configuration is the left channel, the channel configuration module 143 keeps the channel type of the headphones 11 in the left channel. At this time, the headphones 11 remain in the left channel in response to the first signal. When the channel type of the headphones 11 before configuration does not match the target channel type, i.e., the channel type of the headphones 11 before configuration is the right channel, the channel configuration module 143 switches the channel type of the headphones 11 to the left channel. At this time, the headphones 11 switch to the left channel in response to the first signal.

[0282] When the earphone 11 is inserted into the right earphone compartment 232, contact terminal 19 abuts against the right contact terminal 28b to energize it, establishing a communication connection between the earphone 11 and the controller 24 of the earphone case 20. At this time, the earphone 11 can receive a second signal through contact terminal 19 and detect whether the earphone 11 was in the right channel before configuration. If so, it remains in the right channel in response to the second signal. If not, it switches to the right channel in response to the second signal.

[0283] Specifically, the processing module 142 receives the second signal through the contact terminal 19, determines the target channel type of the headphones 11 as the right channel based on the second signal, and judges whether the channel type of the headphones 11 before configuration is consistent with the target channel type, that is, whether the channel type of the headphones 11 before configuration is the right channel. The channel configuration module 143 obtains the judgment result of the processing module 142 and configures the channel type of the headphones 11 according to the judgment result. When the channel type of the headphones 11 before configuration is consistent with the target channel type, that is, the channel type of the headphones 11 before configuration is the right channel, the channel configuration module 143 keeps the channel type of the headphones 11 in the right channel. At this time, the headphones 11 remain in the right channel in response to the second signal. When the channel type of the headphones 11 before configuration is inconsistent with the target channel type, that is, the channel type of the headphones 11 before configuration is the left channel, the channel configuration module 143 switches the channel type of the headphones 11 to the right channel. At this time, the headphones 11 switch to the right channel in response to the second signal.

[0284] In some other embodiments, the processing module 142 may not determine whether the channel type of the earphone 11 before configuration is consistent with the target channel type, and directly send a channel reset signal to the channel configuration module 143. The channel configuration module 143 then resets the earphone 11 to the target channel type based on the channel reset signal. In this case, the processing module 142 receives a first signal or a second signal through the contact terminal 19, obtains the target channel type of the earphone 11 based on the first signal or the second signal, and sends a channel reset signal to the channel configuration module 143. The channel configuration module 143 receives the channel reset signal and configures the channel type of the earphone 11. When the earphone 11 is placed in the left earphone compartment 231, the channel configuration module 143 resets the earphone 11 to the left channel. When the earphone 11 is placed in the right earphone compartment, the channel configuration module 143 resets the earphone 11 to the right channel.

[0285] Understandably, when the controller 14 of the earphone 11 receives the first signal or the second signal, it can control the battery 17 to stop supplying power to functional devices such as the signal transceiver 13, the audio player 15 and the microphone 16, so as to reduce the consumption of the earphone 11 after it is put into the case.

[0286] In the headphone assembly 100 shown in this application embodiment, the two earphones 11 of the headphone 10 do not require special physical error prevention design to distinguish between the earphone 11 worn on the left ear and the earphone 11 worn on the right ear. That is, the structure and shape of the two earphones 11 of the headphone 10 can be designed to be the same, so that the two earphones 11 can share structural components and molds, reducing the types of parts of the headphone 10, reducing production costs to a certain extent, and not requiring strict distinction between the earphone 11 worn on the left ear and the earphone 11 worn on the right ear during production line assembly, which is beneficial to improving production line assembly efficiency.

[0287] In addition, the earphone case 20 has clearly distinguishable left earphone compartment 231 and right earphone compartment 232. Users can freely put the two earphones 11 into the left earphone compartment 231 and the right earphone compartment 232 respectively. The contact terminal 19 of the earphone 11 placed in the left earphone compartment 231 contacts the contact terminal 28a on the left side. The earphone 11 placed in the left earphone compartment 231 can respond to a first signal to configure the channel type as the left channel. The contact terminal 19 of the earphone 11 placed in the right earphone compartment 232 contacts the contact terminal 28b on the right side. The earphone 11 placed in the right earphone compartment 232 can respond to a second signal to configure the channel type as the right channel.

[0288] When using the earphone 10, the user can directly wear the earphone 11 placed in the left earphone compartment 231 in the left earphone and the earphone 11 placed in the right earphone compartment 232 in the right earphone. The user can then listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information from non-corresponding channels, which helps to improve the realism of the sound source and the audio-visual effect.

[0289] In one embodiment, the earphone 11 further includes an information acquisition module 50, which is used to acquire the heartbeat propagation signal at the wearing position of the earphone 11. The heartbeat propagation signal is a signal that changes with the heartbeat, and can be an electrocardiogram waveform or a blood flow pulsation waveform. The information acquisition module 50 is the aforementioned microphone 16, which acquires the heartbeat propagation signal by picking up the low-frequency pulsating noise generated by the carotid artery blood flow impacting the skull on the side of the ear root and then being conducted to the ear canal.

[0290] In other embodiments, the information acquisition module 50 may also acquire the heartbeat propagation signal by picking up the low-frequency pulsating noise of arterial blood flow impacting the skull at the base of the ear from other locations and then transmitting it to the ear canal. Alternatively, the information acquisition module 50 may be a biometric sensor. For example, the information acquisition module 50 may be an electrocardiogram (ECG) sensor, or it may be a photoplethysmography (PPG) sensor.

[0291] The information acquisition module 50 is electrically connected to the controller 14. The controller 14 is also used to receive the heartbeat propagation signal of the wearing position of the earphone 11 acquired by the information acquisition module 50, and send the heartbeat propagation signal of the wearing position of the earphone 11 to the signal transceiver 13. The signal transceiver 13 also sends the heartbeat propagation signal of the wearing position of the earphone 11 to the terminal 200.

[0292] Two earphones 11 are electrically connected to the terminal 200. In this embodiment, the two earphones 11 are wirelessly connected to the terminal 200. When the two earphones 11 are in use, the terminal 200 can determine the wearing position of the two earphones 11, that is, determine the earphone 11 worn in the left ear and the earphone 11 worn in the right ear. Specifically, the terminal 200 includes a position determination module 60, which is used to acquire the heartbeat propagation signals of the wearing positions of the two earphones 11, and determine the wearing positions of the two earphones 11 based on the heartbeat propagation signals of the wearing positions of the two earphones 11, that is, determine the earphone 11 worn in the left ear and the earphone 11 worn in the right ear. The position determination module 60 may be the central processing unit (CPU) of the terminal 200. It can be understood that the terminal 200 includes a signal transceiver module (not shown), and the position determination module 60 acquires the heartbeat propagation signals of the two wearing positions through the signal transceiver module.

[0293] Specifically, the location determination module 60 is used to obtain the electrocardiogram (ECG) waveforms of the two earphone 11 wearing positions based on the heartbeat propagation signals of the two earphone 11 wearing positions. The location determination module 60 removes the time delay of the heartbeat propagation signals from the earphone 11 wearing positions to the terminal 200 to obtain the ECG waveforms of the earphone 11 wearing positions, thereby reducing the operating error of the location determination module 60 and improving its accuracy.

[0294] The position determination module 60 is also used to compare the electrocardiogram waveforms of the two earphones 11 at their wearing positions, and determine which earphone 11 is worn in the left ear and which is worn in the right ear based on the comparison results. Within the same signal cycle, the earphone 11 whose preset position of the heartbeat propagation signal arrives earlier at its wearing position is worn in the left ear, and the earphone 11 whose preset position of the heartbeat propagation signal arrives later at its wearing position is worn in the right ear. The preset position can be the peak position, the start position, or the end position within the same signal cycle.

[0295] It should be understood that the human heart is located on the left side of the body, and the path of the heartbeat from the heart to the left ear is shorter than the path to the right ear. Accordingly, if the heartbeat propagation signal at the location of the left ear is compared with the heartbeat propagation signal at the location of the right ear, it can be seen that for the same signal period at a preset location, the heartbeat propagation signal at the left ear will be earlier than the heartbeat propagation signal at the right ear. This allows us to determine whether the earphone 11 is worn on the left ear or the earphone 11 is worn on the right ear.

[0296] In some other embodiments, a reference position can be added, and the heartbeat propagation signal of the reference position can be obtained. The position determination module 60 can also determine the earphone 11 worn on the left ear and the earphone 11 worn on the right ear by comparing the heartbeat propagation signal of the wearing position of the two earphones 11 with the heartbeat propagation signal of the reference position.

[0297] In addition, the terminal 200 is also used to send a third signal to the earphone 11 worn in the left ear and a fourth signal to the earphone 11 worn in the right ear. Specifically, the position determination module 60 of the terminal 200 is also used to send a third signal to the earphone 11 worn in the left ear and a fourth signal to the earphone 11 worn in the right ear.

[0298] In this embodiment, the earphone 11 can be configured as the left channel in response to a third signal, and can also be configured as the right channel in response to a fourth signal. Specifically, the transceiver 13 receives the third signal or the fourth signal and sends it to the controller 14. The processing module 142 of the controller 14 receives the third signal or the fourth signal, obtains the target channel type of the earphone 11 based on the third signal or the fourth signal, and determines whether the channel type of the earphone 11 before configuration is consistent with the target channel type. The channel configuration module 143 obtains the determination result of the processing module 142, and configures the channel type of the earphone 11 according to the determination result, so that the audio player 15 can play audio of the corresponding channel type later.

[0299] When the earphone 11 is worn in the left ear, the earphone 11 can receive a third signal through the transceiver 13 and detect whether it was in the left channel before configuration. If so, it remains in the left channel in response to the third signal. If not, it switches to the left channel in response to the third signal. It should be understood that the channel of the earphone 11 does not change during the time from when it is worn in the left ear to when the channel is configured. Therefore, the channel type before configuration of the earphone 11 can also refer to the channel type before the earphone 11 is worn in the left ear.

[0300] Specifically, transceiver 13 receives a third signal and sends it to controller 14. Controller 14 receives the third signal and, in response, configures the channel type to the left channel. Processing module 142 receives the third signal through transceiver 13, determines the target channel type of headphones 11 as the left channel based on the third signal, and checks whether the channel type of headphones 11 before configuration matches the target channel type, i.e., whether the channel type of headphones 11 before configuration is the left channel. Channel configuration module 143 obtains the judgment result from processing module 142 and configures the channel type of headphones 11 according to the judgment result. When the channel type of headphones 11 before configuration matches the target channel type, i.e., the channel type of headphones 11 before configuration is the left channel, channel configuration module 143 keeps the channel type of headphones 11 in the left channel. At this time, headphones 11 remain in the left channel in response to the third signal. When the channel type of the headphones 11 before configuration is inconsistent with the target channel type, that is, when the channel type of the headphones 11 before configuration is the right channel, the channel configuration module 143 switches the channel type of the headphones 11 to the left channel. At this time, the headphones 11 switch to the left channel in response to the third signal.

[0301] When the earphone 11 is worn in the right ear, the earphone 11 can receive the fourth signal through the transceiver 13 and detect whether it was in the right channel before configuration. If so, it remains in the right channel in response to the fourth signal. If not, it switches to the right channel in response to the fourth signal. It should be understood that the channel of the earphone 11 does not change during the time from when it is worn in the right ear to when the channel is configured. Therefore, the channel type before configuration of the earphone 11 can also refer to the channel type before the earphone 11 is worn in the right ear.

[0302] Specifically, transceiver 13 receives the fourth signal and sends it to controller 14. Controller 14 receives the fourth signal and, in response, configures the channel type to the right channel. Processing module 142 receives the fourth signal through transceiver 13, determines the target channel type of headphones 11 as the right channel based on the fourth signal, and checks whether the channel type of headphones 11 before configuration matches the target channel type, i.e., whether the channel type of headphones 11 before configuration is the right channel. Channel configuration module 143 obtains the judgment result from processing module 142 and configures the channel type of headphones 11 according to the judgment result. When the channel type of headphones 11 before configuration matches the target channel type, i.e., the channel type of headphones 11 before configuration is the right channel, channel configuration module 143 keeps the channel type of headphones 11 in the right channel. At this time, headphones 11 remain in the right channel in response to the fourth signal. When the channel type of the headphones 11 before configuration is inconsistent with the target channel type, that is, when the channel type of the headphones 11 before configuration is the left channel, the channel configuration module 143 switches the channel type of the headphones 11 to the right channel. At this time, the headphones 11 switch to the right channel in response to the fourth signal.

[0303] In some other embodiments, the processing module 142 may not determine whether the channel type of the earphone 11 before configuration is consistent with the target channel type, and directly send a channel reset signal to the channel configuration module 143. The channel configuration module 143 then resets the earphone 11 to the target channel type based on the channel reset signal. In this case, the processing module 142 receives a third or fourth signal through the transceiver 13, obtains the target channel type of the earphone 11 based on the third or fourth signal, and sends a channel reset signal to the channel configuration module 143. The channel configuration module 143 receives the channel reset signal and configures the channel type of the earphone 11. When the earphone 11 is worn in the left ear, the channel configuration module 143 resets the earphone 11 to the left channel. When the earphone 11 is worn in the right ear, the channel configuration module 143 resets the earphone 11 to the right channel.

[0304] It should be understood that when a user is wearing only one earphone 11, the earphone 10 cannot play stereo sound. Therefore, the terminal 200 will determine the wearing position of the two earphones 11 only when both earphones 11 are in the ear, that is, when the two earphones 11 are worn in the left ear and the right ear respectively, and send a third signal to the earphone 11 worn in the left ear and a fourth signal to the earphone 11 worn in the right ear, so that the channel types of the two earphones 11 are configured to match the channels.

[0305] When only one earphone 11 is in the ear, that is, when only one earphone 11 is worn in the left or right ear, the terminal 200 does not need to determine the wearing position of the earphone 11, and the earphone 11 does not need to be configured for the audio channel. The original audio channel type of the earphone 11 remains unchanged, that is, the audio player 15 of the earphone 11 can directly play audio according to the original audio channel type.

[0306] When using the earphone 10, the user does not need to distinguish between the earphone 11 worn in the left and right ears. The user can freely wear the two earphones 11 in the left and right ears respectively. The information acquisition module 50 of the two earphones 11 respectively acquires the heartbeat transmission signal of the wearing position of the earphone 11. The terminal 200 can determine the earphone 11 worn in the left ear and the earphone 11 worn in the right ear based on the heartbeat transmission signal of the wearing position of the two earphones 11. The two earphones 11 can automatically perform channel configuration according to the signal sent by the terminal 200 to listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information in non-corresponding channels, which helps to improve usage efficiency and user experience.

[0307] Furthermore, in this embodiment, there is no need to add an additional sensor to the earphone 11. The heartbeat propagation signal of the location of the earphone 11 can be directly obtained by the microphone 16 of the earphone 11 to determine whether the earphone 11 is worn on the left ear or the earphone 11 is worn on the right ear, which helps to simplify the structure of the earphone 11.

[0308] It should be understood that, since this embodiment uses the heartbeat propagation signal from the wearing position of the earphone 11 to confirm the wearing position of the earphone 11, the structure of the shell 12 in the earphone 11 is not limited to... Figure 5 The structure shown, including the earplug 121 and the ear rod 122, can also be a bullet or a pill capsule, etc., and this application does not specifically limit it.

[0309] In the second embodiment, the difference from the above embodiment is that the information acquisition module 50 is used to acquire the gravitational acceleration information of the earphone 11 during the wearing process. The gravitational acceleration information includes the direction and trajectory of motion of the earphone 11 during the wearing process. For example, the information acquisition module 50 is a gravity sensor. In other embodiments, the information acquisition module 50 may also be a gyroscope or an electronic compass.

[0310] It should be understood that, since the housing 12 of the earphone 11 shown in this embodiment includes an ear stem 122, the structure of the earphone 11 is subject to certain limitations, i.e., the earphone 11 has limited positions. In other words, when a user wears the earphone 11, the earphone 11 cannot rotate 360° around the ear canal; the earphone 11 can only rotate within a certain range during wear. Because the user's left and right ears are mirror-symmetrically distributed, when the user wears the two earphones 11 in the left and right ears respectively, they will rotate the two earphones 11 in opposite directions until both earphones 11 are in the correct position. At this time, the gravitational acceleration information of the earphones 11 will change. Therefore, the difference in gravitational acceleration information during wear can be used to distinguish between the earphone 11 worn in the left ear and the earphone 11 worn in the right ear.

[0311] Please see Figure 7 and Figure 8 , Figure 7 yes Figure 2 The diagram shows the structure of the earphone 11 in the earphone assembly 100 when it is worn in the left ear. Figure 8 yes Figure 2 A schematic diagram of the structure of the earphone assembly 100 when the earphone 11 is worn on the right ear.

[0312] Terminal 200 is used to receive gravitational acceleration information of the two earphones 11 during the wearing process, and based on the gravitational acceleration information of the two earphones 11 during the wearing process, determines the deflection direction of the wearing position of the two earphones 11 relative to the direction of gravity G, and determines that the wearing position is clockwise relative to the direction of gravity G (e.g., clockwise). Figure 7 The earphone 11, deflected in the ω direction (as shown), is worn on the left ear, and the wearing position is determined to be counterclockwise relative to the direction of gravity G (e.g., ...). Figure 8 The earphone 11, which is deflected in the -ω direction, is worn on the right ear.

[0313] Understandably, when a user wears earphone 11, earphone 11 will eventually be in a position deflected relative to the direction of gravity. Earphone 11 worn in the left ear tends to deflect clockwise relative to the direction of gravity G, while earphone 11 worn in the right ear tends to deflect counterclockwise relative to the direction of gravity G. Therefore, terminal 200 can determine the direction of deflection of the wearing position of the two earphones 11 relative to the direction of gravity G using gravitational acceleration information, thereby identifying which earphone 11 is worn in the left ear and which is worn in the right ear.

[0314] In this embodiment, when using the earphone 10, the user does not need to distinguish between the earphone 11 worn on the left and right ears. The user can wear both earphones 11 on the left and right ears at will. The information acquisition module 50 of the two earphones 11 respectively acquires the gravitational acceleration information during the wearing process of the earphones 11. The terminal 200 can determine the earphone 11 worn on the left ear and the earphone 11 worn on the right ear based on the deflection direction of the wearing position of the two earphones 11 relative to the direction of gravity. The two earphones 11 can automatically configure the sound channels according to the signal sent by the terminal 200 to listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information in non-corresponding channels, which helps to improve the efficiency and user experience.

[0315] In the third embodiment, the difference from the second embodiment is that the terminal 200 is used to receive the gravitational acceleration information of the two earphones 11 during the wearing process, and determines the rotation direction of the two earphones 11 during the wearing process based on the gravitational acceleration information of the two earphones 11 during the wearing process. The earphone 11 that rotates in the clockwise direction is the earphone 11 worn on the left ear, and the earphone 11 that rotates in the counterclockwise direction is the earphone 11 worn on the right ear.

[0316] Understandably, when wearing the earphone 11, users typically first position the ear stem 122 towards the earlobe, and then rotate the earphone 11 to the appropriate position. The earphone 11 worn in the left ear is usually rotated clockwise to the appropriate position, while the earphone 11 worn in the right ear is usually rotated counter-clockwise. Therefore, the terminal 200 can determine the rotation direction of the two earphones 11 during wearing using gravitational acceleration information, thereby identifying the earphone 11 worn in the left ear and the earphone 11 worn in the right ear.

[0317] In this embodiment, when using the earphone 10, the user does not need to distinguish between the earphone 11 worn on the left and right ears. The user can wear both earphones 11 on the left and right ears at will. The information acquisition module 50 of the two earphones 11 respectively acquires the gravitational acceleration information during the wearing process of the earphones 11. The terminal 200 can determine the earphone 11 worn on the left ear and the earphone 11 worn on the right ear based on the rotation direction of the two earphones 11 during the wearing process. The two earphones 11 can automatically configure the sound channels according to the signal sent by the position determination module 60 to listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information on non-corresponding channels, which helps to improve the efficiency and user experience.

[0318] In the fourth embodiment, the difference from the second and third embodiments is that the terminal 200 is used to receive the gravitational acceleration information of the two earphones 11 during the wearing process, determine the user's head movement trajectory based on the gravitational acceleration information of the two earphones 11 during the wearing process, and determine the earphone 11 worn on the left ear and the earphone 11 worn on the right ear based on the user's head movement trajectory.

[0319] For example, the information acquisition module 50 is a gyroscope. When a user wears two earphones 11 and makes a head-nodding motion, the gyroscope of the earphone 11 worn in the right ear will rotate clockwise and the gyroscope of the earphone 11 worn in the left ear will rotate counterclockwise. After acquiring the rotational displacement of the two earphones 11, the terminal 200 can calculate the user's head movement trajectory and then determine whether the user is wearing the earphone 11 worn in the left ear or the earphone 11 worn in the right ear.

[0320] In this embodiment, when using the earphone 10, the user does not need to distinguish between the earphone 11 worn on the left and right ears. The user can wear both earphones 11 on the left and right ears at will. The information acquisition module 50 of both earphones 11 can acquire the gravitational acceleration information during the wearing process of the earphones 11. The terminal 200 can determine the user's head movement trajectory based on the gravitational acceleration information of the two earphones 11 during the wearing process, and thus determine the earphone 11 worn on the left ear and the earphone 11 worn on the right ear. The two earphones 11 can automatically configure the sound channels according to the signal sent by the position determination module 60 to listen to multi-channel audio normally, avoiding the problem of sound field disorder caused by playing audio information on non-corresponding channels, which helps to improve the efficiency and user experience.

[0321] In the fifth embodiment, the difference from the four embodiments described above is that the earphone 11 is configured as the left channel when it is detected that it is worn in the left ear, and as the right channel when it is detected that it is worn in the right ear. Specifically, the information acquisition module 50 of the earphone 11 acquires the gravitational acceleration information of the earphone 11 during the wearing process and sends it to the processing module 142 of the controller 14. The processing module 142 determines whether the earphone 11 is worn in the left or right ear based on the gravitational acceleration information of the earphone 11 during the wearing process. The channel configuration module 143 configures the channel type of the earphone 11 according to the processing result of the processing module 142.

[0322] In some other embodiments, since the two earphones 11 are connected in communication, the processing module 142 can also determine whether the earphone is worn in the left or right ear based on the heartbeat transmission signal of the wearing position of the two earphones 11. This application does not make specific limitations in this regard.

[0323] It should be noted that since stereo playback cannot be achieved when only one earphone 11 is worn, there is no need to configure the channel type of the earphone 11. Therefore, the earphone 11 will only detect its wearing position and configure the corresponding channel according to the wearing position if and only when the two earphones 11 are worn in the left and right ears respectively.

[0324] When the earphone 11 is worn in the left ear, the system checks whether the channel type was previously configured as the left channel. If so, it remains in the left channel. If not, it switches to the left channel. Specifically, the processing module 142 determines the target channel type of the earphone 11 as the left channel based on the wearing position of the earphone 11, and checks whether the channel type of the earphone 11 before configuration matches the target channel type, i.e., whether the channel type of the earphone 11 before configuration is the left channel. The channel configuration module 143 obtains the judgment result from the processing module 142 and configures the channel type of the earphone 11 according to the judgment result. When the channel type of the earphone 11 before configuration matches the target channel type, i.e., the channel type of the earphone 11 before configuration is the left channel, the channel configuration module 143 keeps the channel type of the earphone 11 in the left channel. When the channel type of the earphone 11 before configuration does not match the target channel type, i.e., the channel type of the earphone 11 before configuration is the right channel, the channel configuration module 143 switches the channel type of the earphone 11 to the left channel.

[0325] When the earphone 11 is worn in the right ear, the system checks whether the previous channel was the right channel. If so, it remains in the right channel. If not, it switches to the right channel. Specifically, the processing module 142 determines the target channel type of the earphone 11 as the right channel based on the wearing position of the earphone 11, and checks whether the channel type of the earphone 11 before configuration matches the target channel type, i.e., whether the channel type of the earphone 11 before configuration is the right channel. The channel configuration module 143 obtains the judgment result from the processing module 142 and configures the channel type of the earphone 11 according to the judgment result. When the channel type of the earphone 11 before configuration matches the target channel type, i.e., the channel type of the earphone 11 before configuration is the right channel, the channel configuration module 143 keeps the channel type of the earphone 11 in the right channel. When the channel type of the earphone 11 before configuration does not match the target channel type, i.e., the channel type of the earphone 11 before configuration is the left channel, the channel configuration module 143 switches the channel type of the earphone 11 to the right channel.

[0326] In this embodiment, when using the earphone 10, the user does not need to distinguish between the earphone 11 worn on the left and right ears. The user can wear both earphones 11 on the left and right ears at will. Both earphones 11 can detect whether they are worn on the left or right ear based on the information obtained by the information acquisition module 50, and automatically configure the audio channels according to the detection results to listen to multi-channel audio normally. This avoids the problem of sound field disorder caused by playing audio information on non-corresponding channels, which helps to improve the efficiency and user experience.

[0327] Please see Figure 9 and Figure 10 , Figure 9 yes Figure 2 The diagram shows a modular structure of the earphone housing 20 in another embodiment of the earphone assembly 100. Figure 10 yes Figure 2 The schematic diagram of the module structure of the earphone 11 in the earphone assembly 100 shown in another embodiment.

[0328] The difference between the earphone assembly shown in this embodiment and the earphone assembly 100 shown in the previous embodiment is that the earphone 11 is used to send a detection signal. Specifically, each earphone 11 includes a signal transmitter 111, which is electrically connected to the controller 14 and is used to send a detection signal when inserted into the left earphone compartment 231 or the right earphone compartment 232.

[0329] The earphone case 20 includes a left detection module 20a and a right detection module 20b. The left detection module 20a corresponds to the left earphone compartment 231 and is used to detect a detection signal. The right detection module 20b corresponds to the right earphone compartment 232 and is used to detect a detection signal. The left detection module 20a and the right detection module 20b can be signal receivers.

[0330] When the left detection module 20a detects a detection signal, the earphone case 20 sends a first signal. Specifically, the left detection module 20a is electrically connected to the controller 24. When the earphone 11 is inserted into the left earphone case 231, the left detection module 20a detects a detection signal, the controller 24 confirms that the earphone 11 is inserted into the left earphone case 231, and sends a first signal to the earphone 11 inserted into the left earphone case 231 through the left contact terminal 28a.

[0331] When the right-side detection module 20b detects the detection signal, the earphone case 20 sends a second signal. Specifically, the right-side detection module 20b is electrically connected to the controller 24. When the earphone 11 is inserted into the right earphone case 232, the right-side detection module 20b detects the detection signal, the controller 24 confirms that the earphone 11 is inserted into the right earphone case 232, and sends a second signal to the earphone 11 inserted into the right earphone case 232 through the right-side contact terminal 28b.

[0332] Next, for ease of understanding, the working principle of this embodiment will be explained using the signal transmitter 111 as an infrared light transmitter and the left detection module 20a and right contact terminal 28b as infrared light receivers as an example. Here, the detection signal mentioned above is infrared light.

[0333] It is understandable that when earphone 11 is inserted into the left earphone compartment 231, the left detection module 20a can receive the infrared light emitted by the signal transmitter 111. Similarly, when earphone 11 is inserted into the left earphone compartment 231, the right detection module 20b can receive the infrared light emitted by the signal transmitter 111. Therefore, whether earphone 11 is inserted into the left earphone compartment 231 and the right earphone compartment 232 can be determined by whether the left detection module 20a and the right detection module 20b can detect infrared light.

[0334] In some other embodiments, the earphone 11 may not emit a detection signal. The left detection module 20a and the right detection module 20b may be pressure sensors. The controller 24 uses the pressure detection data from the left detection module 20a and the right detection module 20b to determine whether the earphone 11 is inserted into the left earphone compartment 231 and the right earphone compartment 232. Alternatively, the left detection module 20a and the right detection module 20b may be distance sensors. The controller 24 uses the distance detection data from the left detection module 20a and the right detection module 20b to determine whether the earphone 11 is inserted into the left earphone compartment 231 and the right earphone compartment 232. This application does not specifically limit this method.

[0335] This application provides a third type of headphone assembly, which differs from the two headphone assemblies 100 described above in that the headphone case 20 detects whether the channel of the headphone 11 placed in the left headphone compartment 231 or the right headphone compartment 232 is the target channel type. If it is, the channel configuration ends; otherwise, a channel switching signal is sent. The channel switching signal is used to instruct the headphone 11 to perform a channel switch.

[0336] When earphone 11 is inserted into the left earphone compartment 231, the earphone case 20 detects whether earphone 11 inserted into the left earphone compartment 231 is in the left channel. If so, the channel configuration ends; otherwise, a channel switching signal is sent. Specifically, the processing unit 243 of the controller 24 obtains the channel type of earphone 11 inserted into the left earphone compartment 231 before configuration through the left contact terminal 28a, and detects whether earphone 11 inserted into the left earphone compartment 231 was in the left channel before configuration. When the channel type of earphone 11 inserted into the left earphone compartment 231 before configuration is the left channel, the channel configuration ends. When the channel type of earphone 11 inserted into the left earphone compartment 231 before configuration is the right channel, the processing unit 243 sends a channel switching signal to earphone 11 inserted into the left earphone compartment 231 through the left contact terminal 28a. The earphone 11, which is inserted into the left earphone compartment 231, receives a channel switching signal through the contact terminal 19 and performs channel switching in response to the channel switching signal, switching the channel type to the left channel.

[0337] When earphone 11 is inserted into the right earphone compartment 232, the earphone case 20 detects whether earphone 11 inserted into the right earphone compartment 232 is in the right channel. If so, the channel configuration ends; otherwise, a channel switching signal is sent. Specifically, the processing unit 243 of the controller 24 obtains the channel type of earphone 11 inserted into the right earphone compartment 232 before configuration through the right contact terminal 28b, and detects whether earphone 11 inserted into the right earphone compartment 232 was in the right channel before configuration. When the channel type of earphone 11 inserted into the right earphone compartment 232 before configuration is the right channel, the channel configuration ends. When the channel type of earphone 11 inserted into the right earphone compartment 232 before configuration is the left channel, the processing unit 243 sends a channel switching signal to earphone 11 inserted into the right earphone compartment 232 through the right contact terminal 28b. The earphone 11, inserted into the right earphone compartment 232, receives a channel switching signal through the contact terminal 19 and performs channel switching in response to the channel switching signal, switching the channel type to the right channel.

[0338] This application embodiment also provides a fourth type of headphone assembly. The headphone assembly shown in this embodiment differs from the three headphone assemblies mentioned above in that the headphone 11 is used to detect whether the left headphone compartment 231 or the right headphone compartment 232 is inserted, and is configured to match the sound channel according to the detection result. Specifically, the headphone 11 is configured to use the left sound channel when the left headphone compartment 231 is inserted, and to use the right sound channel when the right headphone compartment 232 is inserted.

[0339] The earphone 11 includes an insertion detection module, which is electrically connected to the controller 14 to detect the insertion environment of the earphone 11. The earphone case 20 includes a left label module and a right label module, with the left label module corresponding to the left earphone compartment 231 and the right label module corresponding to the right earphone compartment 232.

[0340] When the earphone 11 is inserted into the left earphone compartment 231, the insertion detection module detects the left identification module, and the controller 14 confirms that the earphone 11 is inserted into the left earphone compartment 231 and configures the sound channel of the earphone 11 as the left channel.

[0341] When the earphone 11 is inserted into the right earphone compartment 232, the insertion detection module detects the right identification module, and the controller 14 confirms that the earphone 11 is inserted into the right earphone compartment 232 and configures the sound channel of the earphone 11 as the right channel.

[0342] In the headphone assembly shown in this embodiment, the earphone 11 itself detects whether it is inserted into the left earphone compartment 231 or the right earphone compartment 232, and configures itself with the corresponding channel type based on the detection result. When using the earphone 10, the user can directly wear the earphone 11 inserted into the left earphone compartment 231 in the left ear and the earphone 11 inserted into the right earphone compartment 232 in the right ear. Then, the earphone 11 worn in the left and right ears can output audio of the corresponding channel, which can effectively avoid sound field disorder caused by playing audio information of non-corresponding channels, and improve the user's efficiency and user experience.

[0343] Please see Figure 11 , Figure 11 This is a flowchart of a headphone channel configuration method provided in an embodiment of this application.

[0344] This application provides a method for configuring headphone channels, applicable to the headphone assembly 100 described above, for configuring the channel types of the two headphones 11 in the headphone 10. The headphone channel configuration method includes steps S101 and S102.

[0345] In step S101, the headphone assembly 100 detects that the earphone 11 has been inserted into the left earphone compartment 231, and configures the earphone 11 inserted into the left earphone compartment 231 as the left channel. In this embodiment, step S101 can be implemented by steps S103 and S104.

[0346] Please see Figure 12 , Figure 12 yes Figure 11 The flowchart of step S101 in the headphone channel configuration method shown.

[0347] In step S103, the earphone case 20 detects that the earphone 11 has been inserted into the left earphone compartment 231 and sends a first signal.

[0348] Please see Figure 13 , Figure 13 yes Figure 12 The flowchart of step S103 in step S101 shown is presented in one embodiment.

[0349] In one embodiment, step S103 can be implemented through steps S1031 and S1032.

[0350] In step S1031, the headphone case 20 detects that the left headphone compartment 231 contains the earphone 11. Specifically, the headphone case 20 detects whether the left headphone compartment 231 contains the earphone 11. If yes, step S1032 is executed, and a first signal is sent. If no, the detection of whether the left headphone compartment 231 contains the earphone 11 is repeated. In some other embodiments, if the headphone case 20 detects that the left headphone compartment 231 does not contain the earphone 11, the channel configuration can also be terminated.

[0351] In this embodiment, when the case cover 22 is opened relative to the case body 21, the case insertion detection module 30 uses a polling communication method to detect whether the earphone 11 is inserted into the left earphone compartment 231. Specifically, the voltage detection unit 242 detects a first voltage difference ΔV1 and sends it to the processing unit 243. The processing unit 243 compares the first voltage difference ΔV1 with a preset voltage difference ΔV0 stored in the storage unit 241. The first voltage difference ΔV1 is the voltage difference between the two left-side power supply terminals 26a.

[0352] When the first voltage difference ΔV1 is equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that the earphone 11 is placed in the left earphone compartment 231, and sends a first signal to the earphone 11 placed in the left earphone compartment 231 through the left contact terminal 28a.

[0353] When the first voltage difference ΔV1 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 is not fitted with the earphone 11. After that, after a preset time period ΔT stored in the storage unit 241, the voltage detection unit 242 re-acquires the first voltage difference ΔV1 until the first voltage difference ΔV1 is equal to or greater than the preset voltage difference ΔV0.

[0354] It should be understood that when the left earphone compartment 231 is used to insert the earphone 11, the two left-side power supply terminals 26a are respectively connected to the two charging terminals 18 of the earphone 11 to conduct electricity, and there will be a voltage difference between the left-side power supply terminals 26a. Therefore, it can be determined whether the left earphone compartment 231 is used to insert the earphone 11 by detecting the voltage difference between the two left-side power supply terminals 26a.

[0355] Re-reference Figure 12 In step S104, the earphone 11 placed in the left earphone compartment 231 responds to the first signal and is configured as the left channel.

[0356] Please see Figure 14 , Figure 14 yes Figure 12 The flowchart of step S104 in step S101 is shown.

[0357] In this embodiment, step S104 can be implemented through steps S1041 to S1044.

[0358] In step S1041, the earphone 11 inserted into the left earphone compartment 231 receives the first signal. Specifically, the earphone 11 inserted into the left earphone compartment 231 receives the first signal through the contact terminal 19. The controller 14 of the earphone 11 receives the first signal through the contact terminal 19.

[0359] It is understandable that when the left earphone compartment 231 is used to insert the earphone 11, the left contact terminal 28a abuts against the contact terminal 19 of the earphone 11 to conduct electricity, so that the controller 24 of the earphone case 20 and the controller 14 of the earphone 10 can communicate and connect. Therefore, the controller 14 of the earphone 10 can receive the first signal through the contact terminal 19.

[0360] In step S1042, the earphone 11 inserted into the left earphone compartment 231 is checked to see if it was previously configured as the left channel. If yes, step S1043 is executed, and the earphone remains in the left channel in response to the first signal. If no, step S1044 is executed, and the earphone switches to the left channel in response to the first signal.

[0361] Specifically, the processing module 142 of the controller 14 receives the first signal, determines that the target channel type of the headphones 11 is the left channel based on the first signal, and determines whether the channel type of the headphones 11 before configuration is consistent with the target channel type, that is, whether the channel type of the headphones 11 before configuration is the left channel. The channel configuration module 143 obtains the judgment result of the processing module 142 and configures the channel type of the headphones 11 according to the judgment result.

[0362] When the channel type of the headphones 11 before configuration matches the target channel type, i.e., the channel type of the headphones 11 before configuration is the left channel, the channel configuration module 143 keeps the channel type of the headphones 11 in the left channel. At this time, the headphones 11 remain in the left channel in response to the first signal. When the channel type of the headphones 11 before configuration does not match the target channel type, i.e., the channel type of the headphones 11 before configuration is the right channel, the channel configuration module 143 switches the channel type of the headphones 11 to the left channel. At this time, the headphones 11 switch to the left channel in response to the first signal.

[0363] In some other embodiments, the earphone 11 placed in the left earphone compartment 231 may also directly respond to the first signal and reset to the left channel without detecting whether it was configured as the left channel. In this case, the processing module 142 of the controller 14 does not determine whether the channel type of the earphone 11 before configuration is consistent with the target channel type, and directly sends a channel reset signal to the channel configuration module 143 according to the first signal. The channel configuration module 143 resets the channel type of the earphone 11 to the left channel according to the channel reset signal.

[0364] Furthermore, after step S103, step S105 may also be included, in which the earphone case 20 charges the earphone 11 inserted into the left earphone case 231. Specifically, after the processing unit 243 determines that the earphone 11 is inserted into the left earphone case 231, it can also control the battery 25 to start charging the earphone 11 inserted into the left earphone case 231 through the two left power supply terminals 26a, so as to increase the battery life of the earphone 11 inserted into the left earphone case 231 during subsequent use.

[0365] It should be noted that when the power supply terminal 26 and the contact terminal 28 are relatively independent terminals, steps S105 and S104 can be performed simultaneously or sequentially, and this application does not make specific limitations on this. When the power supply terminal 26 integrates the function of the contact terminal 28, the earphone case 20 first configures the channel of the earphone 11 placed in the left earphone compartment 231, and then charges it, that is, it performs step S104 first and then step S105.

[0366] In addition, when the controller 14 of the earphone 11 receives the first signal, it can also control the battery 17 to stop supplying power to functional devices such as the signal transceiver 13, audio player 15 and microphone 16, so as to reduce the consumption of the earphone 11 after it is put into the case.

[0367] Please see Figure 15 , Figure 15 yes Figure 12 The flowchart of step S103 in step S101 shown in another embodiment.

[0368] In this embodiment, step S103 can be implemented through steps S1033 to S1035.

[0369] In step S1033, the earphone 11 transmits a detection signal. Specifically, the signal transmitter 111 of the earphone 11 transmits a detection signal.

[0370] In step S1034, the left detection module 20a of the earphone case 20 detects a detection signal, and the earphone case 20 sends a first signal. Specifically, does the left detection module 20a detect a detection signal? If yes, then step S1035 is executed, and the earphone case 20 sends a first signal to the earphone 11 inserted into the left earphone compartment 231. If no, then the left detection module 20a repeatedly detects the detection signal.

[0371] In this embodiment, when the cover 22 is opened relative to the box body 21, the left detection module 20a continuously detects the detection signal, and the controller 24 determines whether the left earphone compartment 231 is used to insert the earphone 11 based on the detection result of the left detection module 20a.

[0372] When the left detection module 20a detects the detection signal, the controller 24 determines that the earphone 11 is inserted into the left earphone compartment 231, and sends a first signal to the earphone 11 inserted into the left earphone compartment 231 through the left contact terminal 28a.

[0373] When the left detection module 20a does not detect a detection signal, the controller 24 determines that the left earphone compartment 231 is not inhabited by the earphone 11. Thereafter, the left detection module 20a continues to detect the detection signal until it does.

[0374] In some other embodiments, when the lid 22 is opened relative to the body 21, the left detection module 20a may also detect the detection signal intermittently or periodically, which is not specifically limited in this application.

[0375] Next, for ease of understanding, we will take the signal transmitter 111 as an infrared light transmitter and the left detection module 20a as an infrared light receiver as an example to explain the working principle of this embodiment. In this case, the detection signal mentioned above is infrared light.

[0376] It is understandable that when the earphone 11 is inserted into the left earphone compartment 231, the left detection module 20a can receive the infrared light emitted by the signal transmitter 111. Therefore, whether the left detection module 20a can detect the infrared light can be used to determine whether the earphone 11 is inserted into the left earphone compartment 231.

[0377] In some other embodiments, the earphone 11 may not emit a detection signal. The left detection module 20a may be a pressure sensor, and the controller 24 may use the pressure detection data from the left detection module 20a to determine whether the left earphone compartment 231 is in place with the earphone 11. Alternatively, the left detection module 20a may be a distance sensor, and the controller 24 may use the distance detection data from the left detection module 20a to determine whether the left earphone compartment 231 is in place with the earphone 11. This application does not specifically limit this.

[0378] In this embodiment, the headphone channel configuration method further includes step S104'.

[0379] In step S104', the earphone 11 inserted into the left earphone compartment 231 responds to the first signal and is configured as the left channel. Specifically, the earphone 11 inserted into the left earphone compartment 231 receives the first signal and, in response to the first signal, is configured as the left channel. Step S104' is the same as step S104 above and will not be described again here.

[0380] In addition, after step S103, step S105' may also be included, in which the earphone case 20 charges the earphone 11 placed in the left earphone compartment 231. Step S105' is the same as step S105 above, and will not be described again here.

[0381] Re-reference Figure 11 In step S102, the headphone assembly 100 detects that the right headphone 11 has been inserted into the right headphone compartment 232, and configures the headphone 11 inserted into the right headphone compartment 232 as the right channel. It should be understood that steps S101 and S102 can be executed sequentially or simultaneously, and this application does not make a specific limitation in this regard.

[0382] Please see Figure 16 , Figure 16 yes Figure 11The flowchart of step S102 in the headphone channel configuration method shown.

[0383] In this embodiment, step S102 can be implemented through steps S106 and S107.

[0384] In step S106, the earphone case 20 detects that the right earphone compartment 232 has inserted the earphone 11 and sends a second signal.

[0385] Please see Figure 17 , Figure 17 yes Figure 16 The flowchart of step S106 in step S102 shown is presented in one embodiment.

[0386] In one embodiment, step S106 can be implemented by steps S1061 and S1062.

[0387] In step S1061, the headphone case 20 detects whether the right earphone compartment 232 contains the earphone 11. Specifically, the headphone case 20 detects whether the right earphone compartment 232 contains the earphone 11. If yes, step S1062 is executed, and a second signal is sent. If no, the detection process of whether the right earphone compartment 232 contains the earphone 11 is repeated. In some other embodiments, if the headphone case 20 detects that the right earphone compartment 232 does not contain the earphone 11, the channel configuration can also be terminated.

[0388] When the case lid 22 is opened relative to the case body 21, the case insertion detection module 30 uses a polling communication method to detect whether the right earphone compartment 232 has earphone 11 inserted. Specifically, the voltage detection unit 242 detects the second voltage difference ΔV2 and sends it to the processing unit 243. The processing unit 243 compares the second voltage difference ΔV2 with the preset voltage difference ΔV0 stored in the storage unit 241. The second voltage difference ΔV2 is the voltage difference between the two right-side power supply terminals 26b.

[0389] When the second voltage difference ΔV2 is equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that the earphone 11 is placed in the right earphone compartment 232, and sends a second signal to the earphone 11 placed in the right earphone compartment 232 through the right contact terminal 28b.

[0390] When the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the right earphone compartment 232 is not fitted with the earphone 11. After that, after a preset time period ΔT stored in the storage unit 241, the voltage detection unit 242 re-acquires the second voltage difference ΔV2 until the second voltage difference ΔV2 is equal to or greater than the preset voltage difference ΔV0.

[0391] It should be understood that when the right earphone compartment 232 is used to insert the earphone 11, the two right-side power supply terminals 26b are respectively connected to the two charging terminals 18 of the earphone 11 to conduct electricity, and there will be a voltage difference between the right-side power supply terminals 26b. Therefore, it can be determined whether the right earphone compartment 232 is used to insert the earphone 11 by detecting the voltage difference between the two right-side power supply terminals 26b.

[0392] Re-reference Figure 16 In step S107, the earphone 11 inserted into the right earphone compartment 232 responds to the second signal and is configured as the left channel. In this embodiment, step S107 can be implemented through steps S1071 and S1074.

[0393] Please see Figure 18 , Figure 18 yes Figure 16 The flowchart of step S107 in the headphone channel configuration method shown.

[0394] In step S1071, the earphone 11 inserted into the right earphone compartment 232 receives the second signal. Specifically, the earphone 11 inserted into the right earphone compartment 232 receives the second signal through the contact terminal 19. The controller 14 of the earphone 11 receives the second signal through the contact terminal 19.

[0395] It is understandable that when the right earphone compartment 232 is inserted into the earphone 11, the right contact terminal 28b abuts against the contact terminal 19 of the earphone 11 to conduct electricity, so that the controller 24 of the earphone case 20 and the controller 14 of the earphone 10 can communicate and connect. Therefore, the controller 14 of the earphone 10 can receive the second signal through the contact terminal 19.

[0396] In step S1072, the earphone 11 inserted into the right earphone compartment 232 is checked to see if it was previously configured as the right channel. If yes, step S1073 is executed, and the earphone remains in the right channel in response to the second signal. If no, step S1074 is executed, and the earphone switches to the right channel in response to the second signal.

[0397] Specifically, the processing module 142 of the controller 14 receives the second signal, determines the target channel type of the headphones 11 as the left channel based on the second signal, and determines whether the channel type of the headphones 11 before configuration is consistent with the target channel type, that is, whether the channel type of the headphones 11 before configuration is the right channel. The channel configuration module 143 obtains the judgment result of the processing module 142 and configures the channel type of the headphones 11 according to the judgment result.

[0398] When the channel type of the headphones 11 before configuration matches the target channel type, i.e., the channel type of the headphones 11 before configuration is the right channel, the channel configuration module 143 keeps the channel type of the headphones 11 in the right channel. At this time, the headphones 11 remain in the right channel in response to the second signal. When the channel type of the headphones 11 before configuration does not match the target channel type, i.e., the channel type of the headphones 11 before configuration is the left channel, the channel configuration module 143 switches the channel type of the headphones 11 to the right channel. At this time, the headphones 11 switch to the right channel in response to the second signal.

[0399] In some other embodiments, the earphone 11 placed in the right earphone compartment 232 may not need to detect whether it was in the right channel before configuration, and may directly respond to the second signal to reset to the right channel. In this case, the processing module 142 of the controller 14 does not determine whether the channel type of the earphone 11 before configuration is consistent with the target channel type, and directly sends a channel reset signal to the channel configuration module 143 according to the second signal. The channel configuration module 143 resets the channel type of the earphone 11 to the right channel according to the channel reset signal.

[0400] Furthermore, after step S106, step S108 may also be included, in which the earphone case 20 charges the earphone 11 inserted into the right earphone compartment 232. Specifically, after the processing unit 243 determines that the earphone 11 is inserted into the right earphone compartment 232, it can also control the battery 25 to start charging the earphone 11 inserted into the right earphone compartment 232 through the two right-side power supply terminals 26b, so as to increase the battery life of the earphone 11 inserted into the right earphone compartment 232 during subsequent use.

[0401] It should be noted that when the power supply terminal 26 and the contact terminal 28 are relatively independent terminals, steps S107 and S108 can be performed simultaneously or sequentially, and this application does not make specific limitations on this. When the power supply terminal 26 integrates the function of the contact terminal 28, the earphone case 20 first configures the channel of the earphone 11 placed in the right earphone compartment 232, and then charges it, that is, it performs step S107 first, and then step S108.

[0402] In addition, when the controller 14 of the earphone 11 receives the second signal, it can also control the battery 17 to stop supplying power to functional devices such as the signal transceiver 13, audio player 15 and microphone 16, so as to reduce the consumption of the earphone 11 after it is put into the case.

[0403] Please see Figure 19 , Figure 19 yes Figure 16 The flowchart of step S106 in step S102 shown in another embodiment.

[0404] In this embodiment, step S106 can be implemented through steps S1063 to S1065.

[0405] In step S1063, the earphone 11 transmits a detection signal. Specifically, the signal transmitter 111 of the earphone 11 transmits a detection signal.

[0406] In step S1064, the right-side detection module 20b of the earphone case 20 detects a detection signal, and the earphone case 20 sends a second signal to the earphone 11 inserted into the right earphone compartment 232. Specifically, does the right-side detection module 20b detect a detection signal? If yes, then step S1065 is executed, and the earphone case 20 sends a second signal to the earphone 11 inserted into the right earphone compartment 232. If no, then the right-side detection module 20b repeatedly detects the detection signal.

[0407] In this embodiment, when the cover 22 is opened relative to the housing 21, the right detection module 20b continuously detects the detection signal, and the controller 24 determines whether the right earphone compartment 232 is used to insert the earphone 11 based on the detection result of the right detection module 20b.

[0408] When the right detection module 20b detects the detection signal, the controller 24 determines that the right earphone compartment 232 has the earphone 11 inserted, and sends a second signal to the earphone 11 inserted into the right earphone compartment 232 through the right contact terminal 28b.

[0409] When the right detection module 20b does not detect a detection signal, the controller 24 determines that the right earphone compartment 232 is not inhabited by the earphone 11. Thereafter, the right detection module 20b continues to detect the detection signal until it does.

[0410] In some other embodiments, when the lid 22 is opened relative to the box body 21, the right-side detection module 20b may also detect the detection signal intermittently or periodically, which is not specifically limited in this application.

[0411] Next, for ease of understanding, we will take the signal transmitter 111 as an infrared light transmitter and the right-side detection module 20b as an infrared light receiver as an example to explain the working principle of this embodiment. In this case, the detection signal mentioned above is infrared light.

[0412] It is understandable that when the earphone 11 is inserted into the right earphone compartment 232, the right detection module 20b can receive the infrared light emitted by the signal transmitter 111. Therefore, whether the right detection module 20b can detect the infrared light can be used to determine whether the earphone 11 is inserted into the right earphone compartment 232.

[0413] In some other embodiments, the earphone 11 may not emit a detection signal. The right detection module 20b may be a pressure sensor, and the controller 24 may use the pressure detection data from the right detection module 20b to determine whether the right earphone compartment 232 is in place with the earphone 11. Alternatively, the right detection module 20b may be a distance sensor, and the controller 24 may use the distance detection data from the right detection module 20b to determine whether the right earphone compartment 232 is in place with the earphone 11. This application does not specifically limit this.

[0414] In this embodiment, the headphone channel configuration method further includes step S107'.

[0415] In step S107', the earphone 11 inserted into the right earphone compartment 232 responds to the second signal and is configured as the right channel. Specifically, the earphone 11 inserted into the right earphone compartment 232 receives the second signal and, in response to the second signal, is configured as the right channel. Step S107' is the same as step S107 above and will not be described again here.

[0416] In addition, after step S106, step S108' may also be included, in which the earphone case 20 charges the earphone 11 placed in the right earphone compartment 232. Step S108' is the same as step S108 above, and will not be described again here.

[0417] In this embodiment, the two earphones 11 have the same structure and shape, and either earphone 11 can be placed in the left earphone compartment 231 or the right earphone compartment 232. That is, they can be placed in the left earphone compartment 231 and the right earphone compartment 232 of the earphone case 20 without deliberate differentiation, which can realize the quick storage of the earphones 10 by the earphone case 20.

[0418] In the headphone channel control method shown in this application embodiment, the headphone case 20 sends a first signal to the earphone 11 placed in the left earphone compartment 231 and a second signal to the earphone 11 placed in the right earphone compartment 232, so that the earphones 11 placed in the left earphone compartment 231 and the right earphone compartment 232 are configured to match the audio channels. When using the headphone 10, the user can directly wear the earphone 11 placed in the left earphone compartment 231 in the left ear and the earphone 11 placed in the right earphone compartment 232 in the right ear. Then, the earphones 11 worn in the left ear and the right earphones worn in the right ear can output audio from the corresponding audio channels, which can effectively avoid sound field disorder caused by playing audio information from non-corresponding audio channels, and improve the user's efficiency and user experience.

[0419] This application embodiment also provides another method for configuring headphone channels, applicable to the headphone assembly 100 described above, for configuring the channel types of the two headphones 11. The headphone channel configuration method includes steps S201 and S202.

[0420] In step S201, the headphone assembly 100 detects that the earphone 11 has been inserted into the left earphone compartment 231, and configures the earphone 11 inserted into the left earphone compartment 231 as the left channel. In this embodiment, step S201 can be implemented by steps S203 to S207.

[0421] Please see Figure 20 , Figure 20 This is a flowchart of step S201 in another headphone channel configuration method provided in this application embodiment.

[0422] In step S203, the earphone case 20 detects that the left earphone compartment 231 has earphone 11 inserted. Specifically, the earphone case 20 detects whether earphone 11 is inserted into the left earphone compartment 231. If yes, proceed to step S204. If no, repeat step S203.

[0423] In one embodiment, when the case cover 22 is opened relative to the case body 21, the insertion detection module 30 uses a polling communication method to detect whether the left earphone compartment 231 contains the earphone 11. Specifically, the voltage detection unit 242 detects a first voltage difference ΔV1 and sends it to the processing unit 243. The processing unit 243 compares the first voltage difference ΔV1 with a preset voltage difference ΔV0 stored in the storage unit 241. The first voltage difference ΔV1 is the voltage difference between the two left-side power supply terminals 26a.

[0424] When the first voltage difference ΔV1 is equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 is used to insert the earphone 11.

[0425] When the first voltage difference ΔV1 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 is not fitted with the earphone 11. After that, after a preset time period ΔT stored in the storage unit 241, the voltage detection unit 242 re-acquires the first voltage difference ΔV1 until the first voltage difference ΔV1 is equal to or greater than the preset voltage difference ΔV0.

[0426] In another embodiment, the difference from the above embodiment is that step S203 can be implemented by steps S2031 and S2032.

[0427] In step S2031, the earphone 11 transmits a detection signal. Specifically, the signal transmitter 111 of the earphone 11 transmits a detection signal.

[0428] In step S2032, the left detection module 20a of the earphone case 20 detects a detection signal, and the earphone case 20 detects that the left earphone compartment 231 has earphone 11 inserted. In this embodiment, when the case cover 22 is opened relative to the case body 21, the left detection module 20a continuously detects the detection signal, and the controller 24 determines whether the left earphone compartment 231 has earphone 11 inserted based on the detection result of the left detection module 20a.

[0429] When the left detection module 20a detects the detection signal, the controller 24 determines that the left earphone compartment 231 is inhabited with the earphone 11.

[0430] When the left detection module 20a does not detect a detection signal, the controller 24 determines that the left earphone compartment 231 is not inhabited by the earphone 11. Thereafter, the left detection module 20a continues to detect the detection signal until it does.

[0431] In step S204, the headphone case 20 detects whether the earphone 11 inserted into the left earphone compartment 231 was configured as the left channel. If yes, proceed to step S205 to end the channel configuration. If not, proceed to step S206 to send a channel switching signal.

[0432] Specifically, the controller 24 of the headphone case 20 obtains the channel type of the headphone 11 before it is configured by the left contact terminal 28a, determines whether the channel type of the headphone 11 before it is configured is consistent with the target channel type, that is, determines whether the channel type of the headphone 11 before it is configured is the left channel, and sends a channel switching signal according to the determination result.

[0433] When the pre-configuration channel type of the earphone 11 placed in the left earphone compartment 231 is consistent with the target channel type, that is, the pre-configuration channel type of the earphone 11 placed in the left earphone compartment 231 is the left channel, the channel configuration ends. At this time, the earphone 11 placed in the left earphone compartment 231 remains in the left channel.

[0434] When the channel type of the earphone 11 before being configured in the left earphone compartment 231 is inconsistent with the target channel type, that is, the channel type of the earphone 11 before being configured in the left earphone compartment 231 is the right channel, the controller 24 sends a channel switching signal through the left contact terminal 28a.

[0435] In step S207, the earphone 11 inserted into the left earphone compartment 231 switches to the left channel in response to the channel switching signal. Specifically, the earphone 11 inserted into the left earphone compartment 231 receives the channel switching signal and switches to the left channel in response to the channel switching signal.

[0436] In this embodiment, the earphone 11 inserted into the left earphone compartment 231 receives a channel switching signal via the contact terminal 19. The controller 14, which receives the earphone 11 inserted into the left earphone compartment 231, also receives the channel switching signal via the contact terminal 19. Specifically, the processing module 142 of the controller 14 receives the channel switching signal and sends it to the channel configuration module 143. The channel configuration module 143 receives the channel switching signal and switches the channel type of the earphone 11 inserted into the left earphone compartment 231 to the left channel.

[0437] In step S202, the headphone assembly 100 detects that the right headphone 11 has been inserted into the right headphone compartment 232, and configures the headphone 11 inserted into the right headphone compartment 232 as the right channel. It should be understood that steps S201 and S202 can be executed sequentially or simultaneously, and this application does not specifically limit this.

[0438] In this embodiment, step S202 can be implemented through steps S209 to S213.

[0439] Please see Figure 21 , Figure 21 This is a flowchart of step S202 in another headphone channel configuration method provided in this application embodiment.

[0440] In step S209, the earphone case 20 detects that the right earphone compartment 232 has the earphone 11 inserted. Specifically, the earphone case 20 checks whether the right earphone compartment 232 has the earphone 11 inserted. If yes, proceed to step S210. If not, repeat the check.

[0441] In one embodiment, when the case cover 22 is opened relative to the case body 21, the insertion detection module 30 uses a polling communication method to detect whether the right earphone compartment 232 has earphone 11 inserted. Specifically, the voltage detection unit 242 detects a second voltage difference ΔV2 and sends it to the processing unit 243. The processing unit 243 compares the second voltage difference ΔV2 with a preset voltage difference ΔV0 stored in the storage unit 241. The second voltage difference ΔV2 is the voltage difference between the two right-side power supply terminals 26b.

[0442] When the second voltage difference ΔV2 is equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that the right earphone compartment 232 is used to insert the earphone 11.

[0443] When the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the right earphone compartment 232 is not fitted with the earphone 11. After that, after a preset time period ΔT stored in the storage unit 241, the voltage detection unit 242 re-acquires the second voltage difference ΔV2 until the second voltage difference ΔV2 is equal to or greater than the preset voltage difference ΔV0.

[0444] In another embodiment, the difference from the above embodiment is that step S209 can be implemented by steps S2091 and S2092.

[0445] Step S2091, the earphone 11 transmits a detection signal. Specifically, the signal transmitter 111 of the earphone 11 transmits a detection signal.

[0446] In step S2092, the right-side detection module 20b of the earphone case 20 detects a detection signal, and the earphone case 20 detects that the right earphone compartment 232 has been used to insert the earphone 11. In this embodiment, when the case cover 22 is opened relative to the case body 21, the right-side detection module 20b continuously detects the detection signal, and the controller 24 determines whether the right earphone compartment 232 has been used to insert the earphone 11 based on the detection result of the right-side detection module 20b.

[0447] When the right detection module 20b detects the detection signal, the controller 24 determines that the right earphone compartment 232 has the earphone 11 inserted.

[0448] When the right detection module 20b does not detect a detection signal, the controller 24 determines that the right earphone compartment 232 is not inhabited by the earphone 11. Thereafter, the right detection module 20b continues to detect the detection signal until it does.

[0449] In step S210, the headphone case 20 detects whether the headphone 11 inserted into the right headphone compartment 232 is configured as the right channel. If yes, step S211 is executed to end the channel configuration. If not, step S212 is executed to send a channel switching signal.

[0450] Specifically, the controller 24 of the headphone case 20 obtains the channel type of the headphone 11 before it is configured by the right contact terminal 28b, determines whether the channel type of the headphone 11 before it is configured is consistent with the target channel type, that is, determines whether the channel type of the headphone 11 before it is configured is the right channel, and sends a channel switching signal according to the determination result.

[0451] When the pre-configuration channel type of the earphone 11 inserted into the right earphone compartment 232 is consistent with the target channel type, that is, the pre-configuration channel type of the earphone 11 inserted into the right earphone compartment 232 is the right channel, the channel configuration ends. At this time, the earphone 11 inserted into the right earphone compartment 232 remains in the right channel.

[0452] When the channel type of the earphone 11 placed in the right earphone compartment 232 before configuration is inconsistent with the target channel type, that is, the channel type of the earphone 11 placed in the right earphone compartment 232 before configuration is the left channel, the controller 24 sends a channel switching signal through the right contact terminal 28b.

[0453] In step S213, the earphone 11 inserted into the right earphone compartment 232 switches to the right channel in response to the channel switching signal. Specifically, the earphone 11 inserted into the right earphone compartment 232 receives the channel switching signal and switches to the right channel in response to the channel switching signal.

[0454] In this embodiment, the earphone 11 inserted into the right earphone compartment 232 receives a channel switching signal via the contact terminal 19. The controller 14, which receives the earphone 11 inserted into the right earphone compartment 232, also receives the channel switching signal via the contact terminal 19. Specifically, the processing module 142 of the controller 14 receives the channel switching signal and sends it to the channel configuration module 143. The channel configuration module 143 receives the channel switching signal and switches the channel type of the earphone 11 inserted into the left earphone compartment 231 to the right channel.

[0455] In the headphone channel control method shown in this embodiment, the headphone case 20 obtains the channel types of the headphones 11 placed in the left headphone compartment 231 and the headphones 11 placed in the right headphone compartment 232, respectively. It then determines whether the channel types of the headphones 11 in the left and right headphone compartments 231 match the target channel type. Based on the determination result, a channel switching signal is sent to the headphones 11 in the left and right headphone compartments 232, respectively, so that the headphones 11 in the left and right headphone compartments 231 are configured with matching channels. When using the headphones 10, the user can directly wear the headphones 11 in the left headphone compartment 231 in the left ear and the headphones 11 in the right headphone compartment 232 in the right ear. The headphones 11 in the left and right ears will then output audio from the corresponding channels, effectively avoiding sound field distortion caused by playing audio information from non-corresponding channels, thus improving user efficiency and experience.

[0456] This application embodiment also provides a third method for configuring headphone channels, applicable to the headphone assembly 100 described above, for configuring the channel types of the two headphones 11. The headphone channel configuration method includes steps S301 and S302.

[0457] In step S301, the headphone assembly 100 detects that the earphone 11 has been inserted into the left earphone compartment 231, and configures the earphone 11 inserted into the left earphone compartment 231 as the left channel. In this embodiment, the earphone 11 detects that it has been inserted into the left earphone compartment 231 and is configured as the left channel. Specifically, the insertion detection module of the earphone 11 detects the left identification module, and the controller 14 confirms that the earphone 11 has been inserted into the left earphone compartment 231 based on the detection result of the insertion detection module, and configures the channel type as the left channel.

[0458] S302, the headphone assembly 100 detects that the earphone 11 has been inserted into the right earphone compartment 232, and configures the earphone 11 inserted into the right earphone compartment 232 as the right channel. In this embodiment, the earphone 11 detects that it has been inserted into the right earphone compartment 232 and is configured as the right channel. Specifically, the insertion detection module of the earphone 11 detects the right side identification module, and the controller 14 confirms that the earphone 11 has been inserted into the right earphone compartment 232 based on the detection result of the insertion detection module, and configures the channel type as the right channel.

[0459] In the headphone channel control method shown in this application embodiment, the headphone 11 itself detects whether it is inserted into the left headphone compartment 231 or the right headphone compartment 232, and configures it with the corresponding channel type based on the detection result. When using the headphone 10, the user can directly wear the headphone 11 inserted into the left headphone compartment 231 in the left ear and the headphone 11 inserted into the right headphone compartment 232 in the right ear. Then, the headphone 11 worn in the left ear and the headphone 11 worn in the right ear can output audio of the corresponding channel, which can effectively avoid sound field disorder caused by playing audio information in a non-corresponding channel, and improve the user's efficiency and user experience.

[0460] Please see Figure 22 , Figure 22 This is a flowchart of the fourth headphone channel configuration method provided in the embodiments of this application.

[0461] The fourth headphone channel configuration method provided in this application embodiment is applicable to the headphone assembly 100 described above, and is used to configure the channel types of the two headphones 11. The headphone channel configuration method includes steps S401 and S402.

[0462] In step S401, the earphone assembly 100 detects that earphones 11 are inserted into both the left earphone compartment 231 and the right earphone compartment 232. In this embodiment, the earphone case 20 detects that earphones 11 are inserted into both the left earphone compartment 231 and the right earphone compartment 232, sends a first signal to the earphone 11 inserted into the left earphone compartment 231, and sends a second signal to the earphone 11 inserted into the right earphone compartment 232. It should be understood that the earphone case 20 can send the first signal and the second signal simultaneously, or send them one after the other; this application does not specifically limit this.

[0463] Please see Figure 23 , Figure 23 yes Figure 22 The flowchart illustrates one implementation of the headphone channel configuration method.

[0464] In one embodiment, step S401 can be implemented through steps S4011 and S4012.

[0465] In step S4011, the headphone case 20 detects that both the left and right earphone compartments 231 and 232 have earphones 11 inserted. Specifically, the headphone case 20 detects whether both the left and right earphone compartments 231 and 232 have earphones 11 inserted. If yes, then step S4012 is executed, sending a first signal to the earphone 11 inserted in the left earphone compartment 231 and a second signal to the earphone 11 inserted in the right earphone compartment 232. If no, then the detection of whether both the left and right earphone compartments 231 and 232 have earphones 11 inserted is repeated. That is, if at least one of the left and right earphone compartments 231 and 232 has no earphone 11 inserted, then the detection of whether both the left and right earphone compartments 231 and 232 have earphones 11 inserted is repeated. In some other embodiments, if the headphone case 20 detects that at least one of the left and right earphone compartments 231 and 232 has no earphone 11 inserted, the channel configuration can also be terminated.

[0466] When the case lid 22 is opened relative to the case body 21, the insertion detection module 30 uses a polling communication method to detect whether the earphones 11 are inserted into both the left earphone compartment 231 and the right earphone compartment 232. Specifically, the voltage detection unit 242 detects the first voltage difference ΔV1 and the second voltage difference ΔV2, and sends the first voltage difference ΔV1 and the second voltage difference ΔV2 to the processing unit 243. The processing unit 243 compares the first voltage difference ΔV1 and the second voltage difference ΔV2 with the preset voltage difference ΔV0 stored in the storage unit 241. Wherein, the first voltage difference ΔV1 is the voltage difference between the two left power supply terminals 26a, and the second voltage difference ΔV2 is the voltage difference between the two right power supply terminals 26b.

[0467] When the first voltage difference ΔV1 and the second voltage difference ΔV2 are both equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that both the left earphone compartment 231 and the right earphone compartment 232 are filled with earphones 11. It sends a first signal to the earphone 11 placed in the left earphone compartment 231 through the left contact terminal 28a, and sends a second signal to the earphone 11 placed in the right earphone compartment 232 through the right contact terminal 28b.

[0468] When the first voltage difference ΔV1 and / or the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both fitted with earphones 11. That is, when the first voltage difference ΔV1 is less than the preset voltage difference ΔV0 and the second voltage difference ΔV2 is equal to or greater than the preset voltage difference ΔV0, or when the first voltage difference ΔV1 is equal to or greater than the preset voltage difference ΔV0 and the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, or when both the first voltage difference ΔV1 and the second voltage difference ΔV2 are less than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both fitted with earphones 11. In other words, as long as at least one of the left earphone compartment 231 and the right earphone compartment 232 is not fitted with earphones 11, the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both fitted with earphones 11. After that, after the preset time period ΔT stored in the storage unit 241, the voltage detection unit 242 re-acquires the first voltage difference ΔV1 and the second voltage difference ΔV2 until both the first voltage difference ΔV1 and the second voltage difference ΔV2 are equal to or greater than the preset voltage difference ΔV0.

[0469] It should be understood that when earphone 11 is inserted into the left earphone compartment 231, the two left-side power supply terminals 26a abut against the two charging terminals 18 of the earphone 11 inserted into the left earphone compartment 231 to conduct electricity, and a voltage difference will exist between the two left-side power supply terminals 26a. Similarly, when earphone 11 is inserted into the right earphone compartment 232, the two right-side power supply terminals 26b abut against the two charging terminals 18 of the earphone 11 inserted into the right earphone compartment 232 to conduct electricity, and a voltage difference will exist between the two right-side power supply terminals 26b. Therefore, it can be determined whether earphone 11 is inserted into the left earphone compartment 231 and the right earphone compartment 232 by detecting the voltage difference between the two left-side power supply terminals 26a and the voltage difference between the two right-side power supply terminals 26b.

[0470] In step S402, the headphone assembly 100 configures the headphone 11 placed in the left headphone compartment 231 as the left channel and the headphone 11 placed in the right headphone compartment 232 as the right channel.

[0471] In this embodiment, step S402 can be implemented through steps S4021 to S4022.

[0472] In step S4021, the earphone 11 inserted into the left earphone compartment 231 responds to the first signal and is configured as the left channel. Specifically, the earphone 11 inserted into the left earphone compartment 231 receives the first signal and, in response to the first signal, is configured as the left channel. Step S4021 is the same as step S104 above and will not be described again here.

[0473] In step S4022, the earphone 11 inserted into the right earphone compartment 232 responds to the second signal and is configured as the right channel. Specifically, the earphone 11 inserted into the right earphone compartment 232 receives the second signal and, in response to the second signal, is configured as the right channel. Step S4023 is the same as step S107 above and will not be described again here.

[0474] It should be understood that step S4022 can be performed simultaneously with step S4021 or sequentially, and this application does not make specific limitations in this regard.

[0475] Furthermore, after step S401, step S403 may also be included, in which the earphone case 20 charges the earphones 11 placed in the left earphone compartment 231 and the right earphone compartment 232. Specifically, after the processing unit 243 determines that earphones 11 are placed in both the left earphone compartment 231 and the right earphone compartment 232, it can also control the battery 25 to start charging the earphones 11 placed in the left earphone compartment 231 through the two left power supply terminals 26a, and start charging the earphones 11 placed in the right earphone compartment 232 through the two right power supply terminals 26b, so as to increase the battery life of the earphones 11 placed in the left earphone compartment 231 and the right earphone compartment 232 during subsequent use.

[0476] It should be noted that when the power supply terminal 26 and the contact terminal 28 are relatively independent terminals, steps S402 and S403 can be performed simultaneously or sequentially, and this application does not make specific limitations on this. When the power supply terminal 26 integrates the function of the contact terminal 28, the earphone case 20 first configures the channels of the earphones 11 placed in the left earphone compartment 231 and the right earphone compartment 232, and then charges them, that is, step S402 is performed first, and then step S403 is performed.

[0477] Please see Figure 24 , Figure 24 yes Figure 22 The flowchart illustrates another implementation of the headphone channel configuration method.

[0478] In this embodiment, step S401 can be implemented through steps S4013 to S4015.

[0479] In step S4013, both earphones 11 transmit detection signals. Specifically, the signal transmitter 111 of each earphone 11 transmits a detection signal.

[0480] In step S4014, both the left detection module 20a and the right detection module 20b of the earphone case 20 detect the detection signal. Specifically, it checks whether both the left detection module 20a and the right detection module 20b detect the detection signal. If yes, then step S4015 is executed, whereby the earphone case 20 sends a first signal to the earphone 11 inserted into the left earphone compartment 231 and a second signal to the earphone 11 inserted into the right earphone compartment 232. If not, then the left detection module 20a and the right detection module 20b repeatedly detect the detection signal until both the left detection module 20a and the right detection module 20b detect the detection signal.

[0481] In this embodiment, when the case cover 22 is opened relative to the case body 21, the left detection module 20a and the right detection module 20b continuously detect the detection signal. The controller 24 determines whether the left earphone compartment 231 and the right earphone compartment 232 are inhabited based on the detection results of the left detection module 20a and the right detection module 20b. In some other embodiments, when the case cover 22 is opened relative to the case body 21, the left detection module 20a and the right detection module 20b may also detect the detection signal intermittently or periodically. This application does not specifically limit this.

[0482] When both the left detection module 20a and the right detection module 20b detect the detection signal, the controller 24 determines that both the left earphone compartment 231 and the right earphone compartment 232 are inhabited with earphones 11. It sends a first signal to the earphone 11 in the left earphone compartment 231 through the left contact terminal 28a, and sends a second signal to the earphone 11 in the right earphone compartment 232 through the right contact terminal 28b.

[0483] When the left detection module 20a and / or the right detection module 20b does not detect a detection signal, the controller 24 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both equipped with earphones 11. That is, when the left detection module 20a detects a detection signal and the right detection module 20b does not detect a detection signal, or when the left detection module 20a does not detect a detection signal and the right detection module 20b detects a detection signal, or when neither the left detection module 20a nor the right detection module 20b detects a detection signal, the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both equipped with earphones 11. Thereafter, the left detection module 20a and the right detection module 20b continuously detect the detection signal until both the left detection module 20a and the right detection module 20b detect the detection signal.

[0484] Next, for ease of understanding, the working principle of this embodiment will be explained using the signal transmitter 111 as an infrared light transmitter and the left detection module 20a and right detection module 20b as infrared light receivers as an example. Here, the detection signal mentioned above is infrared light.

[0485] Understandably, when earphone 11 is inserted into the left earphone compartment 231, the left detection module 20a can receive the infrared light emitted by the signal transmitter 111. Similarly, when earphone 11 is inserted into the right earphone compartment 232, the right detection module 20b can detect the infrared light emitted by the signal transmitter 111. Therefore, whether earphone 11 is inserted into the left earphone compartment 231 and the right earphone compartment 232 can be determined by whether the left detection module 20a and the right detection module 20b can detect infrared light.

[0486] In some other embodiments, the earphone 11 may not emit a detection signal. The left detection module 20a and the right detection module 20b may be pressure sensors. The controller 24 uses the pressure detection data from the left detection module 20a and the right detection module 20b to determine whether the earphone 11 is placed in the left earphone compartment 231 and the right earphone compartment 232. Alternatively, the left detection module 20a and the right detection module 20b may be distance sensors. The controller 24 uses the distance detection data from the left detection module 20a and the right detection module 20b to determine whether the earphone 11 is placed in the left earphone compartment 231 and the right earphone compartment 232. This application does not make specific limitations on this.

[0487] In this embodiment, step S402 can be implemented through steps S4023 to S4024.

[0488] In step S4023, the earphone 11 inserted into the left earphone compartment 231 responds to the first signal and is configured as the left channel. Specifically, the earphone 11 inserted into the left earphone compartment 231 receives the first signal and, in response to the first signal, is configured as the left channel. Step S4023 is the same as step S4021 above, and will not be described again here.

[0489] In step S4024, the earphone 11 inserted into the right earphone compartment 232 responds to the second signal and is configured as the right channel. Specifically, the earphone 11 inserted into the right earphone compartment 232 receives the second signal and, in response to the second signal, is configured as the right channel. Step S4024 is the same as step S4022 above, and will not be described again here.

[0490] In addition, after step S401, step S404 may also be included, in which the earphone case 20 charges the earphones 11 placed in the left earphone compartment 231 and the right earphone compartment 232. Step S404 is the same as step S403 above, and will not be described again here.

[0491] In the headphone channel control method shown in this embodiment, the two earphones 11 of the headphone 10 do not need to be deliberately distinguished and can be placed arbitrarily into the left earphone compartment 231 and the right earphone compartment 232 of the headphone case 20. The headphone case 20 sends a first signal and a second signal to the earphones 11 placed in the left earphone compartment 231 and the right earphone compartment 232 respectively, so as to configure the channel type of the earphones 11 placed in the left earphone compartment 231 and the right earphone compartment 232 as the left channel and the right channel respectively. When using the headphone 10, the user can directly wear the earphone 11 placed in the left earphone compartment 231 in the left ear and the earphone 11 placed in the right earphone compartment 232 in the right ear. Then, the earphones 11 worn in the left ear and the right earphones worn in the right ear will output audio of the corresponding channel, avoiding sound field disorder caused by playing audio information of the wrong channel, and improving the user's efficiency and user experience.

[0492] This application embodiment also provides a fifth method for configuring headphone channels, applicable to the headphone assembly 100 described above, for configuring the channel types of the two headphones 11. The headphone channel configuration method shown in this embodiment includes steps S501 to S509.

[0493] Please see Figure 25 , Figure 25 This is a flowchart of the fifth headphone channel configuration method provided in the embodiments of this application.

[0494] In step S501, the headphone case 20 detects that both the left and right earphone compartments 231 and 232 contain earphones 11. Specifically, the headphone case 20 checks whether both the left and right earphone compartments 231 and 232 contain earphones 11. If yes, proceed to step S502. If no, repeat step S501. That is, if at least one of the left and right earphone compartments 231 and 232 does not contain an earphone 11, then step S501 is repeated. In some other embodiments, if the headphone case 20 detects that at least one of the left and right earphone compartments 231 and 232 does not contain an earphone 11, the channel configuration can also be terminated.

[0495] In one embodiment, when the case cover 22 is opened relative to the case body 21, the insertion detection module 30 uses a polling communication method to detect whether the earphones 11 are inserted into both the left earphone compartment 231 and the right earphone compartment 232. Specifically, the voltage detection unit 242 detects a first voltage difference ΔV1 and a second voltage difference ΔV2, and sends the first voltage difference ΔV1 and the second voltage difference ΔV2 to the processing unit 243. The processing unit 243 compares the first voltage difference ΔV1 and the second voltage difference ΔV2 with the preset voltage difference ΔV0 stored in the storage unit 241. Here, the first voltage difference ΔV1 is the voltage difference between the two left-side power supply terminals 26a, and the second voltage difference ΔV2 is the voltage difference between the two right-side power supply terminals 26b.

[0496] When the first voltage difference ΔV1 and the second voltage difference ΔV2 are both equal to or greater than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are both filled with earphones 11.

[0497] When the first voltage difference ΔV1 and / or the second voltage difference ΔV2 is less than the preset voltage difference ΔV0, the processing unit 243 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both equipped with earphones 11. Afterwards, after a preset time period ΔT stored in the storage unit 241, the voltage detection unit 242 re-acquires the first voltage difference ΔV1 and the second voltage difference ΔV2 until both the first voltage difference ΔV1 and the second voltage difference ΔV2 are equal to or greater than the preset voltage difference ΔV0.

[0498] In another embodiment, the difference from the above embodiment is that step S501 can be implemented by steps S5011 and S5012.

[0499] In step S5011, both earphones 11 transmit detection signals. Specifically, the signal transmitter 111 of each earphone 11 transmits a detection signal.

[0500] In step S5012, both the left detection module 20a and the right detection module 20b of the earphone case 20 detect the detection signal, and the earphone case 20 is confirmed. In this embodiment, when the case cover 22 is opened relative to the case body 21, the left detection module 20a and the right detection module 20b continuously detect the detection signal, and the controller 24 determines whether the earphone 11 is placed in the left earphone compartment 231 and the right earphone compartment 232 based on the detection results of the left detection module 20a and the right detection module 20b.

[0501] When both the left detection module 20a and the right detection module 20b detect the detection signal, the controller 24 determines that both the left earphone compartment 231 and the right earphone compartment 232 are inhabited with earphones 11.

[0502] When the left detection module 20a and / or the right detection module 20b fails to detect a detection signal, the controller 24 determines that the left earphone compartment 231 and the right earphone compartment 232 are not both inhabited with earphones 11. Thereafter, the left detection module 20a and the right detection module 20b continuously detect the detection signal until both modules detect the signal.

[0503] In step S502, the earphone case 20 detects whether the earphone 11 placed in the left earphone compartment 231 was configured as the left channel. If yes, then step S503 is executed to end the channel configuration. If not, then step S504 is executed to send a channel switching signal.

[0504] In step S505, the earphone 11 inserted into the left earphone compartment 231 switches to the left channel in response to the channel switching signal. Specifically, the earphone 11 inserted into the left earphone compartment 231 receives the channel switching signal and switches to the left channel in response to the channel switching signal.

[0505] Steps S502 to S505 are the same as steps S204 to S207 above, and will not be described again here.

[0506] In step S506, the earphone case 20 detects whether the earphone 11 inserted into the right earphone compartment 232 is configured as the right channel. If yes, then step S507 is executed to end the channel configuration. If not, then step S508 is executed to send a channel switching signal. Step S507 can be performed simultaneously with step S502, or sequentially; this application does not specifically limit this.

[0507] In step S509, the earphone 11 inserted into the right earphone compartment 232 switches to the right channel in response to the channel switching signal. Specifically, the earphone 11 inserted into the right earphone compartment 232 receives the channel switching signal and switches to the right channel in response to the channel switching signal.

[0508] Steps S506 to S509 are the same as steps S209 to S213 above, and will not be described again here.

[0509] In the headphone channel control method shown in this embodiment, the headphone case 20 obtains the channel types of the headphones 11 placed in the left headphone compartment 231 and the headphones 11 placed in the right headphone compartment 232, respectively. It then determines whether the channel types of the headphones 11 in the left and right headphone compartments 231 match the target channel type. Based on the determination result, a channel switching signal is sent to the headphones 11 in the left and right headphone compartments 232, respectively, so that the headphones 11 in the left and right headphone compartments 231 are configured with matching channels. When using the headphones 10, the user can directly wear the headphones 11 in the left headphone compartment 231 in the left ear and the headphones 11 in the right headphone compartment 232 in the right ear. The headphones 11 in the left and right ears will then output audio from the corresponding channels, effectively avoiding sound field distortion caused by playing audio information from non-corresponding channels, thus improving user efficiency and experience.

[0510] This application embodiment also provides a sixth method for configuring headphone channels, applicable to the headphone assembly 100 described above, for configuring the channel types of the two headphones 11. The headphone channel configuration method includes steps S601 and S602.

[0511] In step S601, the two earphones 11 are detected as being placed in the left earphone compartment 231 and the right earphone compartment 232, respectively. Specifically, the placement detection module of one earphone 11 detects the left identification module, and the controller 14 confirms that the earphone 11 is placed in the left earphone compartment 231 based on the detection result of the placement detection module. The placement detection module of the other earphone 11 detects the right identification module, and the controller 14 confirms that the earphone 11 is placed in the left earphone compartment 231 based on the detection result of the placement detection module.

[0512] In step S602, the earphone 11 inserted into the left earphone compartment 231 is configured as the left channel, and the earphone 11 inserted into the right earphone compartment 232 is configured as the right channel. Specifically, the controller 14 of the earphone 11 inserted into the left earphone compartment 231 is configured as the left channel, and the controller 14 of the earphone 11 inserted into the right earphone compartment 232 is configured as the right channel.

[0513] In the headphone channel control method shown in this application embodiment, the headphone 11 itself detects whether it is inserted into the left headphone compartment 231 or the right headphone compartment 232, and configures it with the corresponding channel type based on the detection result. When using the headphone 10, the user can directly wear the headphone 11 inserted into the left headphone compartment 231 in the left ear and the headphone 11 inserted into the right headphone compartment 232 in the right ear. Then, the headphone 11 worn in the left ear and the headphone 11 worn in the right ear can output audio of the corresponding channel, which can effectively avoid sound field disorder caused by playing audio information in a non-corresponding channel, and improve the user's efficiency and user experience.

[0514] It should be understood that when wearing both earphones 11 of the headphone assembly 100, the following scenarios exist:

[0515] When the two earphones 11 are taken out of the earphone case 20 for wearing, if the user can clearly distinguish between the left earphone compartment 231 and the right earphone compartment 232 of the earphone case 20, for example, when the light is sufficient and it is easy to observe the earphone case 20, the user can directly wear the earphone 11 taken out of the left earphone compartment 231 in the left ear and the earphone 11 taken out of the right earphone compartment 232 in the right ear. Since the channel type of the earphone 11 taken out of the earphone compartment 231 must be the left channel and the earphone 11 taken out of the right earphone compartment 232 must be the right channel, both earphones 11 can directly play audio.

[0516] If the user cannot clearly distinguish between the left earphone compartment 231 and the right earphone compartment 232, for example, in dim lighting or when the user is driving and needs to concentrate, the user may not be able to accurately put the earphone 11 taken out of the left earphone compartment 231 into the left ear and the earphone 11 taken out of the right earphone compartment 232 into the right ear. This may result in sound field distortion caused by playing audio information from the wrong channel.

[0517] When the two earphones 11 are not taken out of the earphone case 20 for wearing, but are worn directly outside the earphone case 20, since the two earphones 11 have the same structure and shape, if the user wears the two earphones 11 randomly on the left and right ears, there is a high possibility of sound field disorder caused by non-corresponding audio channel playback.

[0518] Therefore, when using the headphones 10, users also need to reconfigure the channels of the headphones 11 worn in the left and right ears to avoid sound field distortion caused by playing audio information in non-corresponding channels, thereby improving the user experience.

[0519] In one embodiment, two earphones 11 are electrically connected to a terminal 200. The earphones 11 are electrically connected to the terminal 200 via a transceiver 13. The earphone channel configuration method further includes steps S701 to S707.

[0520] Please see Figure 26 , Figure 26 This is a flowchart of some steps in the headphone channel configuration method provided in this application embodiment, under one embodiment.

[0521] In step S701, the information acquisition modules 50 of the two earphones 11 respectively acquire the heartbeat propagation signals at the wearing positions of the two earphones 11. The information acquisition module 50 is a microphone 16 of the earphone 11, which acquires the heartbeat propagation signal by detecting the low-frequency pulsating noise of the carotid artery blood flow impacting the skull at the base of the ear and then being transmitted to the ear canal. Alternatively, the information acquisition module 50 can also be an electrocardiogram sensor or a photoplethysmography (PPG) sensor.

[0522] In step S702, each of the two earphones 11 sends a heartbeat propagation signal based on its wearing position. Specifically, the transceivers 13 of the two earphones 11 send the heartbeat propagation signal based on their respective wearing positions.

[0523] In step S703, the terminal 200 determines the earphone 11 worn in the left ear and the earphone 11 worn in the right ear based on the heartbeat propagation signals of the two earphones 11 at their wearing positions. Specifically, the terminal 200 compares the heartbeat propagation signals of the two earphones 11 at their wearing positions and determines that, within the same signal cycle, the earphone 11 whose heartbeat propagation signal at its preset position arrives earlier is worn in the left ear, and the earphone 11 whose heartbeat propagation signal at its preset position arrives later is worn in the right ear. The preset position can be the start position, end position, or peak position of the signal cycle.

[0524] Specifically, the location determination module 60 of the terminal 200 acquires the heartbeat propagation signals of the wearing positions of the two earphones 11. Based on the heartbeat propagation signals of the two earphones 11, it acquires the electrocardiogram (ECG) waveforms of the wearing positions of the two earphones 11. By comparing the ECG waveforms of the two earphones 11, it determines which earphone 11 is worn in the left ear and which is worn in the right ear based on the comparison result. The location determination module 60 removes the time delay of the heartbeat propagation signals reaching the terminal 200 before obtaining the ECG waveforms of the earphones 11, thereby reducing the operating error of the location determination module 60 and improving its accuracy.

[0525] In step S704, terminal 200 sends a third signal to the earphone 11 worn in the left ear. Specifically, the position determination module 60 of terminal 200 sends a third signal to the earphone 11 worn in the left ear.

[0526] In step S705, the earphone 11 worn in the left ear responds to the third signal and is configured as the left channel. Specifically, the earphone 11 worn in the left ear receives the third signal and, in response to the third signal, is configured as the left channel. The earphone 11 worn in the left ear receives the third signal via the signal transceiver 13.

[0527] In this embodiment, step S705 can be implemented through steps S7051 to S7052.

[0528] Please see Figure 27 , Figure 27 yes Figure 26 The flowchart of step S705 in the headphone channel configuration method shown is shown.

[0529] In step S7051, the earphone 11 worn in the left ear checks whether it was previously configured as the left channel. If yes, then step S7052 is executed, and the earphone remains in the left channel in response to the third signal. If no, then step S7053 is executed, and the earphone switches to the left channel in response to the third signal.

[0530] Specifically, the processing module 142 receives a third signal, determines the target channel type of the headphones 11 as the left channel based on the third signal, and judges whether the channel type of the headphones 11 before configuration is consistent with the target channel type, that is, whether the channel type of the headphones 11 before configuration is the left channel. The channel configuration module 143 obtains the judgment result of the processing module 142 and configures the channel type of the headphones 11 according to the judgment result.

[0531] When the channel type of the headphones 11 before configuration matches the target channel type, i.e., the channel type of the headphones 11 before configuration is the left channel, the channel configuration module 143 keeps the channel type of the headphones 11 in the left channel. At this time, the headphones 11 remain in the left channel in response to the third signal. When the channel type of the headphones 11 before configuration does not match the target channel type, i.e., the channel type of the headphones 11 before configuration is the right channel, the channel configuration module 143 switches the channel type of the headphones 11 to the left channel. At this time, the headphones 11 switch to the left channel in response to the third signal.

[0532] In some other embodiments, the earphone 11 worn on the left ear may also directly respond to the third signal and reset to the left channel without detecting whether it was configured as the left channel. In this case, the processing module 142 of the controller 14 does not determine whether the channel type of the earphone 11 before configuration is consistent with the target channel type, and directly sends a channel reset signal to the channel configuration module 143 according to the third signal. The channel configuration module 143 resets the channel type of the earphone 11 to the left channel according to the channel reset signal.

[0533] Re-reference Figure 26 In step S706, terminal 200 sends a fourth signal to the earphone 11 worn in the right ear. Specifically, the position determination module 60 of terminal 200 sends the fourth signal to the earphone 11 worn in the right ear. Step S706 can be performed simultaneously with step S704, or sequentially; this application does not specifically limit this.

[0534] In step S707, the earphone worn in the right ear responds to the fourth signal and is configured as the right channel. Specifically, the earphone 11 worn in the right ear receives the fourth signal and, in response to the fourth signal, is configured as the left channel. The earphone 11 worn in the right ear receives the fourth signal via the transceiver 13.

[0535] In this embodiment, step S707 can be implemented through steps S7071 to S7073.

[0536] Please see Figure 28 , Figure 28 yes Figure 26 The flowchart of step S707 in the headphone channel configuration method shown is shown.

[0537] Step S7071: The earphone 11 worn on the right ear checks whether it was previously configured as the right channel. If yes, then step S7072 is executed, and the earphone remains in the right channel in response to the fourth signal. If no, then step S7073 is executed, and the earphone switches to the right channel in response to the fourth signal.

[0538] Specifically, the processing module 142 of the controller 14 receives the fourth signal, determines the target channel type of the headphones 11 as the left channel based on the fourth signal, and determines whether the channel type of the headphones 11 before configuration is consistent with the target channel type, that is, whether the channel type of the headphones 11 before configuration is the right channel. The channel configuration module 143 obtains the judgment result of the processing module 142 and configures the channel type of the headphones 11 according to the judgment result.

[0539] When the channel type of the headphones 11 before configuration matches the target channel type, i.e., the channel type of the headphones 11 before configuration is the right channel, the channel configuration module 143 keeps the channel type of the headphones 11 in the right channel. At this time, the headphones 11 remain in the right channel in response to the fourth signal. When the channel type of the headphones 11 before configuration does not match the target channel type, i.e., the channel type of the headphones 11 before configuration is the left channel, the channel configuration module 143 switches the channel type of the headphones 11 to the right channel. At this time, the headphones 11 switch to the right channel in response to the fourth signal.

[0540] In some other embodiments, the earphone 11 worn on the right ear may also directly respond to the fourth signal and reset to the right channel without detecting whether it was configured as the right channel before configuration. In this case, the processing module 142 of the controller 14 does not determine whether the channel type of the earphone 11 before configuration is consistent with the target channel type, and directly sends a channel reset signal to the channel configuration module 143 according to the fourth signal. The channel configuration module 143 resets the channel type of the earphone 11 to the right channel according to the channel reset signal.

[0541] It should be understood that when a user is wearing only one earphone 11, earphone 10 cannot play stereo sound. Therefore, the terminal 200 will only determine the wearing position of the two earphones 11 when the in-ear detection module 40 of both earphones 11 detects that both earphones 11 are in the ear, that is, when the two earphones 11 are worn in the left ear and the right ear respectively, so that the channel type of the two earphones 11 is configured to match the channel. When only one earphone 11 is in the ear, that is, when only one earphone 11 is worn in the left ear or the right ear, the terminal 200 does not need to determine the wearing position of the earphone 11, and the earphone 11 does not need to be configured for the channel. The original channel type of the earphone 11 remains unchanged, and the audio player 15 of the earphone 11 can directly play audio according to the original channel type.

[0542] When using the earphone 10, the user does not need to distinguish between the earphone 11 worn in the left and right ears. The user can wear the two earphones 11 in the left and right ears at will. The information acquisition module 50 of both earphones 11 can obtain the heartbeat transmission signal of the wearing position of the earphone 11. The terminal 200 can determine the earphone 11 worn in the left ear and the earphone 11 worn in the right ear based on the heartbeat transmission signal of the wearing position of the two earphones 11. The two earphones 11 can automatically configure the sound channels according to the signal sent by the terminal 200 to listen to multi-channel audio normally. This avoids the problem of sound field disorder caused by playing audio information in non-corresponding channels, which helps to improve the efficiency and user experience.

[0543] In another embodiment, the headphone channel configuration method further includes steps S801 to S807.

[0544] Please see Figure 29 , Figure 29 This is a flowchart of some steps in the headphone channel configuration method provided in this application embodiment under another embodiment.

[0545] In step S801, the information acquisition modules 50 of the two earphones 11 respectively acquire the gravitational acceleration information of the two earphones 11 during the wearing process. The information acquisition module 50 is a gravity sensor. Alternatively, the information acquisition module 50 can also be a gyroscope or an electronic compass.

[0546] In step S802, each of the two earphones 11 transmits its own gravitational acceleration information during the wearing process. Specifically, the transceivers 13 of the two earphones 11 transmit their respective gravitational acceleration information during the wearing process.

[0547] It should be understood that, since the housing 12 of the earphone 11 shown in this embodiment includes an ear stem 122, the structure of the earphone 11 is subject to certain limitations, i.e., the earphone 11 has limited positions. In other words, when a user wears the earphone 11, the earphone 11 cannot rotate 360° around the ear canal; the earphone 11 can only rotate within a certain range during wear. Because the user's left and right ears are mirror-symmetrically distributed, when the user wears the two earphones 11 on their left and right ears respectively, they will rotate the two earphones 11 in opposite directions until both earphones 11 are in the correct position. At this time, the gravitational acceleration information of the earphones 11 will change, therefore, the gravitational acceleration information of the two earphones 11 will differ during wear.

[0548] In step S803, the terminal 200 determines the earphone 11 worn in the left ear and the earphone 11 worn in the right ear based on the gravitational acceleration information during the wearing process of the two earphones 11. Specifically, the position determination module 60 of the terminal 200 acquires the gravitational acceleration information during the wearing process of the two earphones 11, and determines the earphone 11 worn in the left ear and the earphone 11 worn in the right ear based on the gravitational acceleration information during the wearing process of the two earphones 11.

[0549] In one embodiment, the terminal 200 determines the direction of the deflection of the wearing position of the two earphones 11 relative to the direction of gravity G based on the gravitational acceleration information during the wearing process of the two earphones 11, and determines that the wearing position is clockwise (e.g., clockwise) relative to the direction of gravity G. Figure 7 The earphone 11, deflected in the ω direction (as shown), is worn on the left ear, and the wearing position is determined to be counterclockwise relative to the direction of gravity (e.g., ...). Figure 8 The earphone 11, which is deflected in the -ω direction, is worn on the right ear.

[0550] It is understood that, since the earphone 11 shown in this embodiment includes an ear stem 122, the earphone 11 cannot rotate 360° around the ear canal; that is, the earphone 11 can only rotate within a certain range during wear. When a user wears the earphone 11, the earphone 11 will eventually be in a position deflected relative to the direction of gravity. The earphone 11 worn on the left ear tends to deflect clockwise relative to the direction of gravity, while the earphone 11 worn on the right ear tends to deflect counterclockwise relative to the direction of gravity. Therefore, the position determination module 60 can determine the angle between the wearing position of the two earphones 11 and the direction of gravity using gravitational acceleration information, thereby determining which earphone 11 is worn on the left ear and which earphone 11 is worn on the right ear.

[0551] In another embodiment, the terminal 200 determines the rotation direction of the two earphones 11 during the wearing process based on the gravitational acceleration information of the two earphones 11, and determines that the earphone 11 that rotates clockwise during the wearing process is worn on the left ear, and the earphone 11 that rotates counterclockwise during the wearing process is worn on the right ear.

[0552] It is understood that, since the earphone 11 shown in this embodiment includes an ear stem 122, the earphone 11 cannot rotate 360° around the ear canal; that is, the earphone 11 can only rotate within a certain range during wear. When wearing the earphone 11, the user generally first places the ear stem 122 towards the earlobe, and then rotates the earphone 11 to a suitable position. The earphone 11 worn in the left ear is often rotated clockwise to a suitable position, while the earphone 11 worn in the right ear is often rotated counterclockwise. Therefore, the position determination module 60 of the terminal 200 can determine which earphone 11 is worn in the left ear and which is worn in the right ear based on the rotation direction of the two earphones 11 during wear.

[0553] In the third embodiment, the terminal 200 determines the user's head movement trajectory based on the gravitational acceleration information of the two earphones 11 during the wearing process, and determines the earphone 11 worn on the left ear and the earphone 11 worn on the right ear based on the user's head movement trajectory.

[0554] For example, the information acquisition module 50 of the earphone 11 is a gyroscope. When the user wears both earphones 11 and makes a head-nodding motion, the gyroscope of the earphone 11 worn in the left ear will rotate counterclockwise, and the gyroscope of the earphone 11 worn in the right ear will rotate clockwise. After acquiring the rotational displacement of the gyroscopes of the two earphones 11, the position determination module 60 can obtain the user's head movement trajectory and thus determine which earphone 11 is worn in the left ear and which earphone 11 is worn in the right ear.

[0555] In step S804, terminal 200 sends a third signal to the earphone 11 worn in the left ear. Specifically, the position determination module 60 of terminal 200 sends a third signal to the earphone 11 worn in the left ear.

[0556] In step S805, the earphone 11 worn in the left ear responds to the third signal and is configured as the left channel. Specifically, the earphone 11 worn in the left ear receives the third signal and, in response to the third signal, is configured as the left channel. The earphone 11 worn in the left ear receives the third signal via the signal transceiver 13.

[0557] In this embodiment, steps S804 and S805 are the same as steps S704 and S705 above, and will not be described again here.

[0558] In step S806, terminal 200 sends a fourth signal to the earphone 11 worn in the right ear. Specifically, the location determination module 60 of terminal 200 sends the fourth signal to the earphone 11 worn in the right ear. Step S706 can be performed simultaneously with step S704, or sequentially; this application does not specifically limit this.

[0559] In step S807, the earphone worn in the right ear responds to the fourth signal and is configured as the right channel. Specifically, the earphone 11 worn in the right ear receives the fourth signal and, in response to the fourth signal, is configured as the left channel. The earphone 11 worn in the right ear receives the fourth signal via the transceiver 13.

[0560] In this embodiment, steps S806 and S807 are the same as steps S706 and S707 above, and will not be described again here.

[0561] In the headphone channel configuration method shown in this embodiment, when using the headphones 10, the user does not need to deliberately distinguish between the headphones 11 worn on the left and right ears. The two headphones 11 can be worn on the left and right ears at will. The information acquisition module 50 of the two headphones 11 can acquire the gravitational acceleration information during the wearing process of the headphones 11 respectively. The terminal 200 can determine the headphones 11 worn on the left ear and the headphones 11 worn on the right ear based on the gravitational acceleration information during the wearing process of the two headphones 11. The two headphones 11 can automatically switch channels according to the signal sent by the terminal 200 to listen to multi-channel audio normally. Without human intervention, the channels of the two headphones 11 can be configured to output matching audio, avoiding the problem of sound field disorder caused by playing audio information on non-corresponding channels, which helps to improve the efficiency and user experience.

[0562] In the third embodiment, the headphone channel configuration method further includes steps S901 to S904.

[0563] Please see Figure 30 , Figure 30 This is a flowchart of some steps of the headphone channel configuration method according to an embodiment of this application in a third embodiment.

[0564] In step S901, the two earphones 11 are detected as being worn in the left and right ears respectively. Specifically, the in-ear detection module 40 of both earphones 11 detects that the earphones 11 are in the ear.

[0565] In step S902, the two earphones 11 determine which earphone 11 is worn in the left ear and which earphone 11 is worn in the right ear. Specifically, the two earphones 11 determine which earphone 11 is worn in the left ear and which earphone 11 is worn in the right ear based on the heartbeat propagation signal or gravitational acceleration information obtained by the information acquisition module 50 of the two earphones 11.

[0566] Step S903: The earphone worn in the left ear is configured as the left channel. Specifically, the earphone 11 worn in the left ear checks whether it was previously configured as the left channel. If so, it remains in the left channel. If not, it switches to the left channel. In some other embodiments, the earphone 11 worn in the left ear may not check the channel type before configuration and directly reset to the left channel; this application does not specifically limit this.

[0567] Step S904: The earphone worn in the right ear is configured as the right channel. Specifically, the earphone 11 worn in the right ear checks whether it was previously configured as the right channel. If so, it remains in the right channel. If not, it switches to the right channel. In some other embodiments, the earphone 11 worn in the right ear may not check the channel type before configuration and directly reset to the right channel; this application does not specifically limit this.

[0568] In the headphone channel configuration method of this application embodiment, when using the headphones 10, the user does not need to distinguish which headphone 11 is worn in the left ear and which is worn in the right ear. The user can wear both headphones 11 in the left and right ears at will. The two headphones 11 can use the information obtained by the information acquisition module 50 to determine which headphone 11 is worn in the left ear and which is worn in the right ear. Without human intervention, the two headphones 11 can automatically configure the channels to output matching audio, avoiding sound field disorder caused by playing audio information in non-corresponding channels, and improving the user's efficiency and user experience.

[0569] This application also provides a computer-readable medium for storing a headphone channel configuration program. When the headphone channel configuration program is executed, it implements any of the headphone channel configuration methods described above.

[0570] The above are merely some embodiments and implementation methods of this application. The scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
