[0059] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0060] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0061] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0062] This application provides a true wireless Bluetooth headset, which can be used as an accessory for terminal devices in scenarios such as calls. The terminal device includes, but is not limited to, handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem. The terminal device may include cellular phones, smartphones, personal digital assistant (PDA) computers, tablet computers, laptop computers, in-vehicle computers, smartwatches, smart bracelets, pedometers, and other terminal devices with call functionality. In this application, the terminal device may also be referred to as a terminal. Call scenarios include, but are not limited to, indoor call scenarios, outdoor call scenarios, and in-vehicle call scenarios. Call scenarios may also include quiet call scenarios, noisy call scenarios (e.g., streets, shopping malls, airports, train stations, construction sites, in the rain, watching a game, concerts, etc.), cycling call scenarios, windy outdoor call scenarios, single-ear call scenarios, binaural call scenarios, and other scenarios where calls can be made.

[0063] Headphones (also known as headphone, headset, or earpiece) can be a pair of transducers used to receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears.

[0064] Headphones can generally be divided into wired headphones (wired headphones or wired headsets) and wireless headphones. Wired headphones consist of two earpieces and a connecting cable, with the left and right earpieces connected via the cable. Wired headphones can be inconvenient to wear and require a headphone jack to connect to a terminal device, consuming the terminal device's power during operation. Wireless headphones, on the other hand, utilize wireless communication technologies (such as Bluetooth, infrared radio frequency technology, 2.4G wireless technology, and ultrasound) to communicate with terminal devices. Compared to wired headphones, wireless headphones are more convenient to use because they are free from the constraints of physical wires, thus experiencing rapid development. In wireless headphones, the left earpiece can connect to the right earpiece via Bluetooth.

[0065] Bluetooth is a low-cost, high-capacity, short-range wireless communication standard. Operating in the microwave frequency band, it boasts a transmission rate of 1 megabyte per second and a maximum transmission distance of 10 meters, which can be increased to 100 meters by adding transmission power. With the removal of headphone jacks from some terminal devices and the widespread adoption and updates of Bluetooth technology, a wide variety of wireless Bluetooth headsets have flooded the market. From early business-oriented single-ear Bluetooth headsets for calls, to stereo Bluetooth headsets supporting music playback, and finally to truly wireless Bluetooth headsets that completely eliminate wires, wireless headsets are becoming increasingly feature-rich and applicable to a wider range of scenarios.

[0066] True wireless Bluetooth earbuds, also known as true wireless stereo (TWS) earbuds, completely eliminate wired connections. They consist of two earbuds (e.g., the master earbud and the slave earbud). For example, during use, a terminal device (also called a transmitting device, such as a mobile phone, tablet, or music player with Bluetooth output) wirelessly connects to the master earbud, which then wirelessly connects to the slave earbud via Bluetooth, achieving true wireless separation of the left and right channels. The left and right earbuds of true wireless Bluetooth earbuds can form a stereo system via Bluetooth, improving performance for music playback, calls, and comfort. Furthermore, either earbud can work independently; for example, when the master earbud is not connected to the slave earbud, it can revert to mono sound quality. Due to the lack of physical connection between the left and right earbuds, almost all true wireless Bluetooth earbuds come with a charging case that also serves as a storage container. The case provides power and storage for the earbuds; when the power is low, simply placing the earbuds in the case automatically disconnects them from other electronic devices via Bluetooth, and the case charges them.

[0067] Before introducing the prompting method of the embodiments of this application, the true wireless Bluetooth headset system will be introduced first.

[0068] Figure 1A schematic diagram of a true wireless Bluetooth headset system is shown.

[0069] like Figure 1 As shown, the true wireless Bluetooth earphone system includes an earphone case lid 110, an earphone case body 120, and wireless earphones 130. The earphone case includes the earphone case body 120 and the earphone case lid 110. The earphone case body 120 is provided with a receiving compartment for receiving the wireless earphones. The earphone case lid 110 is used to close the receiving compartment. The earphone case body 120 and the earphone case lid 110 can be rotatably connected or snap-fit ​​connected, that is, the earphone case body 120 and the earphone case lid 120 can rotate relative to each other or the earphone case lid 110 can be separated from the earphone case body 120.

[0070] It should be noted that, Figure 1 The illustration provided is merely an example of a true wireless Bluetooth earphone system. The true wireless Bluetooth earphone system provided in this application includes, but is not limited to, [other examples]. Figure 1 The shown is a true wireless Bluetooth earphone system.

[0071] Figure 2 A schematic diagram of the structure of a wireless headset 130 is shown. The wireless headset may include a processor 201, a memory 202, a wireless communication module 203, an audio module 204, a power supply module 205, an input / output interface 206, a sensor module 207, etc. The processor 201 may include one or more interfaces for connecting to other modules of the wireless headset 200.

[0072] The memory 202 can be used to store program code, such as for charging the wireless earphone 200, wireless pairing and connecting the wireless earphone 200 with other electronic devices, and transmitting audio signals.

[0073] The processor 201 can be used to execute the aforementioned application code and call relevant modules to implement different functions. For example, it can implement functions such as charging the wireless headset 200, wireless communication, audio signal transmission, and in / out box detection. The processor 201 may include one or more processing units, which can be independent devices or integrated into one or more processors 201. Specifically, the processor 201 may be an integrated control chip or a circuit comprising various active and / or passive components, configured to perform the functions belonging to the processor 201 described in the embodiments of this application.

[0074] The sensor module 207 may include a distance sensor and / or a proximity light sensor. The processor 201 can determine whether the wireless earphone 200 is being worn by a user based on data collected by the distance sensor or the proximity light sensor. For example, the processor 201 can use data collected by the distance sensor to detect whether there is an object near the wireless earphone 200, thereby determining whether the wireless earphone 200 is being worn by a user. In some embodiments, the wireless earphone 200 may also include a bone conduction sensor, forming a bone conduction earphone. Using this bone conduction sensor, the processor 201 can acquire the vibration signal of the sound-emitting bone block, parse the voice signal, and realize the voice function. It should be noted that this embodiment only uses the determination of whether the wireless earphone 200 is being worn by a user based on a distance sensor as an example, but it is not limited to this; the processor 201 can also determine whether the wireless earphone 200 is being worn by a user based on other sensors.

[0075] The sensor module 207 may further include a magnetic sensor for detecting the magnetic field strength around the wireless earphone 200. When the wireless earphone 200 is inside the receiving compartment of the earphone case, the magnetic field around the wireless earphone 200 is a first magnetic field, and the magnetic field strength detected by the magnetic sensor in the first magnetic field is a first intensity range. When the wireless earphone 200 is outside the receiving compartment of the earphone case, the magnetic field around the wireless earphone 200 is a second magnetic field, and the magnetic field strength detected by the magnetic sensor in the second magnetic field is a second intensity range. The first intensity range and the second intensity range do not overlap. When the magnetic sensor detects a magnetic field strength in the first intensity range, it outputs a first signal to the processor 201. When the magnetic sensor detects a magnetic field strength in the second intensity range, it outputs a second signal to the processor 201. The first signal is high and the second signal is low, or the first signal is low and the second signal is high. The processor 201 determines that the wireless earphone 200 has left the earphone case in response to the signal transmitted by the magnetic sensor changing from the first signal to the second signal, and determines that the wireless earphone 200 has been inserted into the earphone case in response to the signal transmitted by the magnetic sensor changing from the second signal to the first signal. It should be noted that this embodiment of the application only takes the determination of the entry and exit of the wireless earphone 200 based on the magnetic sensor as an example, but it is not limited to this. The processor 201 can also determine the entry and exit of the wireless earphone 200 based on other sensors.

[0076] The wireless communication module 203 can be used to support data exchange between the wireless headset 200 and other electronic devices or headphone cases, including Bluetooth (BT), Global Navigation Satellite System (GNSS), Wireless Local Area Networks (WLAN), (such as Wireless Fidelity (Wi-Fi) networks), Frequency Modulation (FM), Near Field Communication (NFC), and Infrared (IR) technologies. In some embodiments, the wireless communication module 203 can be a Bluetooth chip. The wireless headset 200 can pair with and establish a wireless connection with the Bluetooth chips of other electronic devices through this Bluetooth chip to achieve wireless communication between the wireless headset 200 and other electronic devices.

[0077] In addition, the wireless communication module 203 may also include an antenna. The wireless communication module 203 receives electromagnetic waves through the antenna, modulates and filters the electromagnetic wave signal, and sends the processed signal to the processor 201. The wireless communication module 203 may also receive signals to be transmitted from the processor 201, modulate and amplify them, and then convert them into electromagnetic waves for radiation through the antenna.

[0078] The audio module 204 can be used to manage audio data and enable the wireless headset 200 to input and output audio signals. For example, the audio module 204 can acquire audio signals from or transmit audio signals to the wireless communication module 203, enabling functions such as making and receiving calls, playing music, activating / deactivating the voice assistant of an electronic device connected to the headset, and receiving / sending user voice data through the wireless headset itself. The audio module 204 may include a speaker (or earpiece, receiver) assembly for outputting audio signals, a microphone (or microphone), and a microphone recording circuit that works with the microphone. The speaker can be used to convert audio electrical signals into sound signals and play them. The microphone can be used to convert audio signals into electrical signals. The audio module 204 (such as a speaker, also called a "horn") includes a magnet. The magnetic field around the wireless headset 200 includes the magnetic field generated by this magnet. The magnetic field generated by this magnet affects the magnitude of the magnetic induction intensity collected by the magnetic sensor of the wireless headset 200.

[0079] The power module 205 provides system power to the wireless headset 200, supplying power to its various modules and supporting charging input. The power module 205 may include a power management unit (PMU) and a battery (i.e., the first battery). The PMU may include a charging circuit, a voltage drop regulation circuit, a protection circuit, and a power measurement circuit. The charging circuit receives external charging input. The voltage drop regulation circuit transforms the electrical signal input to the charging circuit and outputs it to the battery to charge it; it can also transform the electrical signal input from the battery and output it to other modules such as the audio module 204 and the wireless communication module 203. The protection circuit prevents overcharging, over-discharging, short circuits, or overcurrent. In some embodiments, the power module 205 may also include a wireless charging coil for wirelessly charging the wireless headset 200. Additionally, the power management unit can monitor parameters such as battery capacity, battery cycle count, and battery health status (leakage current, impedance).

[0080] Input / output interface 206 can be used to provide a wired connection for charging or communication between the wireless earphone 200 and the earphone case. In some embodiments, input / output interface 206 may include an earphone electrical connector for conducting and transmitting current. When the wireless earphone 200 is placed in the storage compartment of the earphone case, the wireless earphone 200 can establish an electrical connection with the electrical connector in the earphone case through the earphone electrical connector (e.g., the earphone electrical connector makes direct contact with the electrical connector in the earphone case). After the electrical connection is established, the earphone case can charge the battery in the wireless earphone 200 through the current transmission function of the earphone electrical connector and the electrical connector in the earphone case. For example, the earphone electrical connector can be a pogo pin, spring pin, spring, conductive block, conductive patch, conductive sheet, pin, plug, contact pad, jack, or socket, etc. The specific type of electrical connector is not limited in the embodiments of this application. In other embodiments, after the electrical connection is established, the wireless earphone 200 can also communicate data with the earphone case, for example, it can receive pairing instructions from the earphone case.

[0081] It is understood that the structure illustrated in the embodiments of this application does not constitute a specific limitation on the wireless earphone 200. It may have more than Figure 2 The diagram shows more or fewer components, two or more components can be combined, or there can be different component configurations.

[0082] Figure 2 The various components shown can be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing or application-specific integrated circuits.

[0083] Figure 3A schematic diagram of the headphone case 300 is shown. The headphone may include a processor 301, a memory 302, a wireless communication module 303, an audio module 304, a power module 305, an input / output interface 306, a sensor module 307, a display module 308, etc. The processor 301 may include one or more interfaces for connecting to other modules of the wireless headphone 200.

[0084] The memory 302 can be used to store program code, such as code for charging the headphone case 300 and for the headphone case 300 to receive audio signals played by the headphones.

[0085] The processor 301 can be used to execute the aforementioned application code and call relevant modules to implement different functions. For example, it can implement the charging function of the headphone case 300, the audio signal receiving function, and the function of detecting the opening and closing of the headphone case lid. The processor 301 may include one or more processing units, which can be independent devices or integrated into one or more processors 301. Specifically, the processor 301 may be an integrated control chip or a circuit comprising various active and / or passive components, and this circuit is configured to perform the functions belonging to the processor 301 described in the embodiments of this application.

[0086] The sensor module 307 may include a first pressure sensor. The processor 301 can determine whether the headphone case is open or closed based on the data collected by the first pressure sensor. For example, when the headphone case is closed, the impedance detected by the first pressure sensor is a first impedance, and the processor outputs a third signal to the processor 301. When the headphone case is open, the impedance detected by the first pressure sensor is a second impedance, and the processor outputs a fourth signal to the processor 301. The third signal is high-level and the fourth signal is low-level, or vice versa. The processor 301 determines that the headphone case is open when the signal transmitted by the first pressure sensor changes from the first signal to the second signal, and determines that the headphone case is closed when the signal transmitted by the first pressure sensor changes from the second signal to the first signal. It should be noted that this embodiment only uses the determination of whether the headphone case 300 is closed based on a pressure sensor as an example, but it is not limited to this. The processor 301 can also determine whether the headphone case 300 is closed based on other sensors.

[0087] The sensor module 307 may further include a second pressure sensor. The processor 301 can determine whether the wireless earbuds have left the earphone case based on data collected by the second pressure sensor. For example, the second pressure sensor is located at the bottom of the left and right earphone compartments. When the left wireless earbud is in the compartment, the second pressure sensor detects a third impedance and outputs a fifth signal to the processor. When the right wireless earbud is in the compartment, the second pressure sensor detects a fourth impedance and outputs a sixth signal to the processor. When the left wireless earbud is not in the compartment, the second pressure sensor detects a fifth impedance and outputs a seventh signal to the processor. When the right wireless earbud is not in the compartment, the second pressure sensor detects a sixth impedance and outputs an eighth signal to the processor. The fifth and sixth signals are high-level, and the seventh and eighth signals are low-level. When the processor responds to the signal transmitted by the second sensor changing from the fifth and sixth signals to the seventh and eighth signals, it determines that both the left and right wireless earbuds have left the earphone case. It should be noted that the embodiments of this application only take the determination of whether the left and right wireless earbuds are in the earbud box based on the pressure sensor as an example, but it is not limited to this. The processor 301 can also determine whether the left and right wireless earbuds are in the earbud box based on other sensors.

[0088] The wireless communication module 303 can be used to support data exchange between the earphone case 300 and other electronic devices or wireless earphones, including via Bluetooth, Global Navigation Satellite System, wireless local area network such as Wi-Fi, FM, short-range wireless communication technology, infrared technology, and other wireless communication technologies. In some embodiments, the wireless communication module 303 can be a Bluetooth chip.

[0089] In addition, the wireless communication module 303 may also include an antenna. The wireless communication module 303 receives electromagnetic waves through the antenna, modulates and filters the electromagnetic wave signal, and sends the processed signal to the processor 301. The wireless communication module 303 may also receive signals to be transmitted from the processor 301, modulate and amplify them, and then convert them into electromagnetic waves for radiation through the antenna.

[0090] The audio module 304 can be used to manage audio data and enable audio signal input to the headphone box. The audio module 304 may include a microphone (or transducer), a microphone recording circuit that works with the microphone, etc. The microphone can be used to convert audio signals into electrical signals.

[0091] The display module 308 may include insertion indicator lights, which may include a left insertion indicator light and a right insertion indicator light. These indicator lights can be controlled by the processor 301 to illuminate the corresponding insertion indicator light when the headphone case receives an audio signal sent by the wireless headphones. See the following description for details. The display module 308 may also include a battery indicator light, which can be used to indicate the remaining battery power of the headphone case.

[0092] Existing true wireless Bluetooth earbuds often have similar colors and shapes for the left and right earbuds, making it difficult for users to accurately insert them into the correct compartments when placing them in the charging case. This application provides a method for indicating which earbuds should be inserted into the charging case. By incorporating an insertion indicator light within the charging case, the light clearly guides the user to insert the earbuds into the correct compartments, preventing incorrect insertion.

[0093] The following is combined Figure 4 and Figure 5 This application describes a method for receiving audio signals using an earphone box, as described in the embodiments of this application.

[0094] Figure 4 A circuit schematic of an earphone case receiving audio signals is shown. The processor 401 can detect when the earphone case is opened via the earphone case switch detection circuit 404. In response to the earphone case being opened, the processor 401 can control the opening switch Q1.

[0095] For example, the processor 401 can detect the opening of the headphone case via the headphone case opening / closing detection circuit 404 by detecting the opening / closing of the headphone case through a signal output by a pressure sensor. For instance, when the headphone case is closed, the pressure sensor detects a first impedance and outputs a third signal to the processor 401; when the headphone case is open, the pressure sensor detects a second impedance and outputs a fourth signal to the processor 401, where the third signal is high and the fourth signal is low, or vice versa. The processor 401 determines the headphone case is open when the signal transmitted by the pressure sensor changes from the third signal to the fourth signal, and determines the headphone case is closed when the signal transmitted by the pressure sensor changes from the fourth signal to the third signal.

[0096] After the processor turns on switch Q1, the filtering and analog-to-digital conversion circuit 402 and the microphone 403 begin to operate. After the microphone 403 acquires the audio signal, it converts the audio signal into an electrical signal, which is then input to the filtering and analog-to-digital conversion circuit 402. The filtering and analog-to-digital conversion circuit 402 converts the electrical signal into a digital signal and inputs it to the processor 401. The processor 401 can determine the source of the audio signal based on the input digital signal and control the display module to illuminate the corresponding insertion indicator light. Please refer to the following description for details.

[0097] When the processor 401 detects that the headphone case is closed via the headphone case switch detection circuit 404, the processor 401 can control the switch Q1 to turn off, the filtering and analog-to-digital conversion circuit 402 and the microphone 403 will no longer work, and the processor 401 will no longer receive the digital signal input by the filtering and analog-to-digital conversion circuit. Then the processor 401 can control the display module to turn off the insertion indicator light. For details, please refer to the following description.

[0098] Optionally, the processor 401 can also detect whether the headphones are in the headphone case through the headphone detection circuit 405. When the processor 401 detects that the headphones are in the headphone case through the headphone detection circuit 405, the processor can control the off switch Q1 without closing the headphone case lid.

[0099] Figure 5 A circuit diagram of another headphone case for receiving audio signals is shown. Switch Q2 closes in response to the headphone case opening.

[0100] For example, switch Q2 can be a mechanical switch that can be triggered to close in response to the opening of the headphone case.

[0101] For example, switch Q2 can be a switch sensor that closes in response to the opening of the headphone case.

[0102] Processor 501 can detect the on / off state of switch Q2. When switch Q2 is closed, processor 501 can control switch Q3 to open. When switch Q3 is open, the filtering and analog-to-digital conversion circuit 502 and microphone 503 start working. After the microphone 503 collects the audio signal, it converts the audio signal into an electrical signal and inputs it into the filtering and analog-to-digital conversion circuit 502. The filtering and analog-to-digital conversion circuit 502 converts the electrical signal into a digital signal and inputs it into processor 501. Processor 501 can determine the source of the audio signal based on the input digital signal and control the display module to light up the corresponding insertion indicator.

[0103] In response to the closing of the headphone case and the opening of switch Q2, processor 501 can detect the on / off state of switch Q2. When switch Q2 is on, processor 501 can control switch Q3 to be closed. When switch Q3 is closed, the filtering and analog-to-digital conversion circuit 502 and microphone 503 no longer work, and processor 501 no longer receives digital signals input by the filtering and analog-to-digital conversion circuit. Then processor 401 can control the display module to turn off the insertion indicator light.

[0104] Figure 6 A schematic flowchart illustrating the process of receiving audio signals using an earphone box according to an embodiment of this application is shown, such as... Figure 6 As shown in (a) above, the process includes:

[0105] S601, the earphone case detected the user opening the lid.

[0106] The headphone case can detect when the user opens the lid. For a description of the headphone case opening detection, please refer to the previous description, which will not be repeated here.

[0107] S602, the headphone case begins receiving audio signals.

[0108] The headphone case detects the user opening the lid and, in response, receives audio signals via its microphone. For a description of how the headphone case receives audio signals, please refer to the previous section; it will not be repeated here.

[0109] S603, the earphone case determines whether an audio signal is received.

[0110] The headphone case can determine whether it is receiving an audio signal. Upon detecting a user opening the case, the headphone case activates its microphone to receive the audio signal and converts it into an electrical signal, which is then input to a filtering and analog-to-digital converter (ADC) circuit. This circuit converts the electrical signal into a digital signal, which is then input to the processor. If the processor does not receive this digital signal, it determines that the headphone case is not receiving an audio signal and executes step S604. If the processor receives the digital signal, it determines that the headphone case is receiving an audio signal, and the headphone case continues to receive audio signals. The corresponding insertion indicator light will illuminate based on the received audio signal. See the following description for details.

[0111] S604, the earphone case determines whether both left and right wireless earphones are inside the earphone case.

[0112] The earphone case can detect whether both left and right wireless earbuds are inside the case. When both earbuds are inside, step S605 is executed; when at least one earbud is not inside, the earphone case continues to receive audio signals. For a description of how the earphone case determines whether both earbuds are inside, please refer to the previous description, which will not be repeated here.

[0113] S605, the headphone case has stopped receiving audio signals.

[0114] When the earphone case detects that all the wireless earphones are inside the case, it can stop receiving audio signals.

[0115] Optionally, after the earphone case detects the user opening the lid, such as... Figure 6 As shown in (b) above, the method may further include:

[0116] S607, the earphone case starts the first timer.

[0117] Upon detecting that the headphone case has been opened, the headphone case can activate a first timer, which can be used to control the duration of audio signal reception by the headphone case. The processor can execute the first timer program code stored in memory to implement the function of controlling the duration of audio signal reception by the headphone case. The first timer can also be a mechanical or electronic timer, and this application does not limit it to this.

[0118] In one embodiment, the earphone box can receive audio signals after the first timer is started.

[0119] In one embodiment, the earphone box can simultaneously receive audio signals and start a first timer.

[0120] It should be noted that when the headphone case starts the first timer, the judgment condition of S604 can be adjusted to S608.

[0121] S608, the earphone case determines whether the first timer has expired or whether both left and right wireless earphones are in the earphone case.

[0122] The earphone case can detect whether both left and right wireless earphones are inside the earphone case. When the earphone case detects that both left and right wireless earphones are inside the earphone case, it proceeds to S605. When the earphone case detects that at least one wireless earphone is not inside the earphone case, the earphone case can continue to receive audio signals. Alternatively, the earphone case can detect whether the first timer has timed out. When the time of the first timer is less than or equal to the first time threshold, it continues to receive audio signals. When the time of the first timer is greater than the first time threshold, it proceeds to S605.

[0123] For example, with a first time threshold of 10 seconds, the headphone case can stop receiving audio signals if the time it takes to receive the audio signal exceeds 10 seconds. By controlling the audio signal reception time of the headphone case through the first timer, the power consumption of the headphone case can be saved, and its usage time can be increased.

[0124] Optionally, before the headphone case starts receiving audio signals, such as Figure 6 As shown in (c) above, the method may further include:

[0125] S609, the earphone case determines whether both left and right wireless earphones are inside the earphone case.

[0126] The earphone case detects the user's opening operation. In response to this operation, the earphone case can detect whether both left and right wireless earphones are inside the earphone case. When both left and right wireless earphones are inside the earphone case, S606 is executed; when at least one of the left and right earphones is not inside the earphone case, S602 is executed.

[0127] In one implementation, the method may include both S607 and S609.

[0128] It should be understood that there is no actual order between S607 and S609.

[0129] The following is combined Figure 7 and Figure 8 This application describes a method for opening the headphone case and inserting the indicator light in an embodiment of the present application.

[0130] Figure 7 A circuit diagram of an earphone case with an open insertion indicator light is shown. After the microphone 705 collects the audio signal, it can convert the audio signal into an electrical signal and input it to the filtering and analog-to-digital conversion circuit 704. The filtering and analog-to-digital conversion circuit 704 can convert the electrical signal into a digital signal and input it to the processor 701.

[0131] The processor 701 can determine whether the audio signal is from the left or right wireless earphone based on the input digital signal. When the processor 701 determines that the audio signal is from the left wireless earphone, the processor can control the switch Q4 to turn on, and the left insertion indicator 702 will light up. When the processor 701 determines that the audio signal is from the right wireless earphone, the processor can control the switch Q5 to turn on, and the right insertion indicator 703 will light up.

[0132] Figure 8 A schematic diagram showing the distribution of the insertion indicator lights is provided.

[0133] like Figure 8 As shown in (a), the left insertion indicator can be located at the bottom of the left compartment, and the right insertion indicator can be located at the bottom of the right compartment.

[0134] like Figure 8 As shown in (b), the left insertion indicator can be set on one side of the left receiving compartment, and the right insertion indicator can be set on one side of the right receiving compartment.

[0135] For example, such as Figure 8 As shown in (b), the left insertion indicator can be located on the right side of the left receiving compartment, and the right insertion indicator can be located on the left side of the right receiving compartment.

[0136] For example, the left insertion indicator light can be located on the left side of the left receiving compartment, and the right insertion indicator light can be located on the right side of the right receiving compartment.

[0137] For example, the left insertion indicator light can be located on the upper (or lower) side of the left receiving compartment, and the right insertion indicator light can be located on the upper (or lower) side of the right receiving compartment.

[0138] Optionally, the left insertion indicator and the right insertion indicator can be different or the same color.

[0139] The following is combined Figure 9This application describes a method for transmitting audio signals after the wireless earphone is removed from the ear or the earphone case.

[0140] Figure 9 This illustration shows a schematic flowchart of how wireless earphones transmit audio signals after being removed from the ear or the earphone case, as provided in an embodiment of this application. Figure 9 As shown in (a) above, the process includes:

[0141] S901, in response to detecting that a first preset condition is met, the wireless earphone sends an audio signal.

[0142] Wireless earbuds can detect their current status, such as whether they are in the ear or in the charging case. For a description of how they detect whether the earbuds are in the ear or in the charging case, please refer to the previous description; it will not be repeated here.

[0143] When the wireless earbuds detect that a first preset condition is met, they can send an audio signal. For example, the first preset condition could be: the wireless earbuds are not in the ear and / or not in the charging case. Specifically, the wireless earbuds can use sensors to detect whether they are in the ear or in the charging case. When the wireless earbuds are removed from the ear or the charging case, the processor can control the speaker to send an audio signal. To distinguish between the left and right wireless earbuds, the audio signals sent by the left and right earbuds can be different; the left earbud sends a first audio signal, and the right earbud sends a second audio signal.

[0144] For example, the frequencies of the first audio signal and the second audio signal can be different; for instance, the frequency of the first audio signal is 20 kHz and the frequency of the second audio signal is 21 kHz.

[0145] For example, the first audio signal has the same frequency as the second audio signal, but the transmission patterns are different. The transmission pattern can be understood as the way the headphones transmit audio signals. For instance, the transmission pattern of the first audio signal is to transmit the first audio signal for 0.5 seconds, pause for 0.5 seconds, and repeat this cycle. The transmission pattern of the second audio signal is to transmit the second audio signal for 1 second, pause for 1 second, and repeat this cycle.

[0146] It should be noted that the above embodiments are illustrated using the example of different frequencies or different transmission modes of the first audio signal and the second audio signal. It can be understood that the frequencies and transmission modes of the first audio signal and the second audio signal can be different.

[0147] Optionally, the first audio signal and the second audio signal can be high-frequency audio signals that are inaudible to the human ear (e.g., audio signals with a frequency of 20KHz-23KHz).

[0148] S902, the wireless earphones detect when the user inserts the wireless earphones into the earphone case or puts the wireless earphones into the ear.

[0149] The wireless earphones can determine whether the user has inserted the earphones into the charging case or whether the earphones are in the ear. If the earphones do not detect the user inserting the earphones into the charging case or putting the earphones in the ear, they continue to send audio signals. This audio signal can be associated with the insertion indicator light in the charging case. When the charging case receives the audio signal, it will light up the corresponding insertion indicator light. If the earphones detect the user inserting the earphones into the charging case or putting the earphones in the ear, they will proceed to step S904. For a description of how the earphones determine whether they are inserted into the charging case or whether they are in the ear, please refer to the previous description; it will not be repeated here.

[0150] S903, in response to the user inserting the wireless earphones into the earphone case or putting the wireless earphones into the ear, the wireless earphones stop sending audio signals.

[0151] The wireless earphones can stop sending audio signals once they detect that the earphones have been inserted into the charging case or that they have been put into the ear.

[0152] Optionally, after the wireless earbuds detect that the earbuds are away from the ear or removed from the charging case, such as Figure 9 As shown in (b) above, the method may further include:

[0153] S905, the wireless earphone starts the second timer.

[0154] After the wireless earphone detects that a first preset condition has been met, it can activate a second timer. This second timer can be used to control the timing of audio signal transmission by the wireless earphone. The processor can execute the second timer program code stored in memory to implement the function of controlling the timing of audio signal transmission by the wireless earphone. The second timer can also be a mechanical or electronic timer, and this application does not limit it to this.

[0155] In one embodiment, the wireless earphones may send audio signals after a second timer is started.

[0156] In one embodiment, the wireless earphone can simultaneously transmit audio signals and start a second timer.

[0157] It should be noted that when the wireless earphone starts the second timer, the judgment condition of S903 can be adjusted to S907.

[0158] S906: The wireless earphone detects that the second timer has expired or that the user has inserted the wireless earphone into the earphone case or put the wireless earphone into their ear.

[0159] The wireless earphones can use sensors to determine whether the user has inserted the earphones into the charging case or whether the earphones are in the ear. If the wireless earphones do not detect the user inserting the earphones into the charging case or putting the earphones in the ear, the wireless earphones continue to send audio signals. When the wireless earphones detect the user inserting the earphones into the charging case or putting the earphones in the ear, in response to this operation, S904 is executed; or the wireless earphones can detect whether the second timer has timed out. If the timeout of the second timer is less than or equal to the second time threshold, the audio signal continues to be sent; if the timeout of the second timer is greater than the second time threshold, S904 is executed.

[0160] For example, with a second time threshold of 5 seconds, the headphones can stop sending audio signals if the transmission time exceeds 5 seconds. Controlling the audio signal transmission time via a second timer can save battery power and extend the headphones' lifespan.

[0161] The following is combined Figure 10 This application describes a method for prompting the user to insert wireless earphones into their case.

[0162] Figure 10 A schematic flowchart illustrating the method for prompting the user to insert wireless earphones into their case, as provided in an embodiment of this application, is shown. Figure 10 As shown, the process includes:

[0163] S1001, the earphone case detected the user opening the lid.

[0164] S1002, in response to the user opening the case, the headphone case begins to receive audio signals.

[0165] In response to the user opening the case, the headphone case can receive audio signals via its microphone. For a description of the headphone case receiving audio signals, please refer to the previous section; it will not be repeated here.

[0166] S1003, the headphone case determines whether it has received an audio signal.

[0167] The headphone case can determine whether an audio signal is received. The audio signal is sent by the wireless earbuds. When the wireless earbuds detect that the earbuds are removed from the ear or the headphone case, they can control the speakers to send audio signals through the processor. The audio signal sent by the left wireless earbud is the first audio signal, and the audio signal sent by the right wireless earbud is the second audio signal. If the headphone case determines that no audio signal is received, it proceeds to step S1005; if the headphone case determines that an audio signal is received, it proceeds to step S1004.

[0168] S1004, the headphone case detects the audio signal and illuminates the corresponding insertion indicator light.

[0169] When the headphone box detects an audio signal through the microphone, it converts the audio signal into an electrical signal. After passing through a filtering and analog-to-digital conversion circuit, the signal is input into the processor as a digital signal. The processor can then determine the source of the audio signal and control the corresponding insertion indicator light to illuminate, thus repeating the process.

[0170] For example, when the processor determines that the audio signal is the first audio signal sent by the left wireless earphone, the left insertion indicator light will illuminate. After the user inserts the left wireless earphone into the headphone case, when the headphone case detects the second audio signal sent by the right wireless earphone, the right insertion indicator light will illuminate.

[0171] It should be noted that when the headphone case detects both the first audio signal sent by the left wireless earbud and the second audio signal sent by the right wireless earbud, the headphone case can determine the distance between the left and right wireless earbuds and the headphone case, and will first light up the insertion indicator light corresponding to the wireless earbud that is closer to the case.

[0172] For example, the headphone case can determine the distance between the left and right wireless earbuds and the case by: the headphone case determining the distance between the earbuds and the case based on the sound intensity of the received first audio signal and the second audio signal, and / or, the headphone case and earbuds can determine the distance via Bluetooth or an antenna. For instance, if the headphone case receives both the first and second audio signals simultaneously, and detects that the sound intensity of the first audio signal is greater than that of the second audio signal, then it determines that the distance between the left wireless earbud and the case is less than the distance between the right wireless earbud and the case, and the left insertion indicator light on the headphone case will illuminate first.

[0173] Optionally, the insertion indicator light for the wireless earbuds can be turned off after they are plugged in. For example, when the processor determines that the audio signal is being sent by the left wireless earbud, the left insertion indicator light will illuminate; after the user plugs the left wireless earbud into the headphone case, the left insertion indicator light can be turned off.

[0174] S1005, the headphone case does not light up the insertion indicator light.

[0175] When the headphone case does not receive an audio signal, or the intensity of the received audio signal is less than or equal to a third threshold, the headphone case can control the status of the left and right insertion indicator lights. For example, the headphone case can measure the sound intensity using a dual-microphone method. The headphone case can include a first microphone and a second microphone, positioned face-to-face. The headphone case can measure a first sound pressure level (SPL) signal and a second SPL signal using the first and second microphones. Based on the first and second SPL signals, a third SPL signal at the midpoint between the first and second microphones can be obtained. The sound intensity can then be calculated using the sound intensity formula and the third SPL signal. When the headphone case measures a sound intensity less than or equal to the third threshold, it can turn off the left and right insertion indicator lights. By controlling the insertion indicator lights by measuring the audio signal intensity, the headphone case can ensure that the indicator lights only illuminate when the wireless headphones are close to the headphone case, thus saving power to some extent.

[0176] The fact that the headphone case doesn't light up the insertion indicator light means that the headphone case can control the insertion indicator light to turn off or keep it off. For example, when the headphone case receives an audio signal and lights up the corresponding insertion indicator light, it can turn off the insertion indicator light when it no longer receives an audio signal, or it can keep the insertion indicator light off when the headphone case does not receive an audio signal.

[0177] S1006, the headphone case has stopped receiving audio signals.

[0178] Optionally, in response to the user opening the case, before the headphone case begins receiving audio signals, such as... Figure 10 As shown in (b) above, the method may further include:

[0179] S1008, the earphone case determines whether both left and right wireless earphones are inside the earphone case.

[0180] In response to the user's opening of the case, the earphone case can detect whether both left and right wireless earphones are inside the case. If both left and right wireless earphones are inside the case, proceed to S1007; if at least one of the left and right wireless earphones is not inside the case, proceed to S1002.

[0181] In this embodiment, the wireless earphones can send audio signals after being removed from the case or ear. When the user inserts the wireless earphones into the earphone case, the earphone case can receive the audio signals sent by the wireless earphones, and the earphone case can light up the insertion indicator light to indicate to the user that the earphones are inserted into the correct storage compartment, which improves efficiency and user experience.

[0182] The following is combined Figure 11 This application describes another method for indicating when wireless earphones are placed in their case.

[0183] Figure 11A schematic flowchart illustrating the method for prompting the user to insert wireless earphones into their case, as provided in an embodiment of this application, is shown. Figure 11 As shown, the process includes:

[0184] S1101, the earphone case detected the user opening the lid.

[0185] S1102, in response to the user opening the case, the earphone case starts the first timer.

[0186] S1103, in response to the user opening the case, the headphone case begins to receive audio signals.

[0187] S1104, the headphone box determines whether it has received an audio signal.

[0188] It should be noted that the descriptions of S1101-S1104 can be found in the foregoing embodiments, and will not be repeated here.

[0189] S1105, the earphone case detects the audio signal and lights up the corresponding indicator light.

[0190] When the headphone case detects an audio signal through the microphone, it converts the audio signal into an electrical signal. This signal is then filtered and converted to a digital signal by an analog-to-digital converter, which inputs it into the processor. The processor can then determine the source of the audio signal and control the corresponding insertion indicator light to illuminate, repeating this cycle. For example, if the headphone case determines the audio signal is the first audio signal, it can control the left insertion indicator light to illuminate.

[0191] S1106, the earphone case determines whether the first timer has expired or whether both left and right wireless earphones are inside the earphone case.

[0192] It should be noted that the description of S1106 can be found in the foregoing embodiments, and will not be repeated here.

[0193] S1107, the headphone case does not light up the insertion indicator light.

[0194] When the headphone case does not receive an audio signal, or the intensity of the received audio signal is less than or equal to a third threshold, the insertion indicator light on the headphone case may not illuminate. For example, when the headphone case responds to a user opening the case and begins receiving an audio signal, the corresponding insertion indicator light may illuminate. When the headphone case no longer receives an audio signal (e.g., when the user places the wireless headphones into the case or into their ears), the insertion indicator light may be turned off. As another example, when the headphone case responds to a user opening the case and begins receiving an audio signal, but does not receive an audio signal, the insertion indicator light may remain off.

[0195] In another embodiment, the earphone box can first control the status of the left and right insertion indicator lights, and then the earphone box determines whether the first timer has expired or whether both left and right wireless earphones are inside the earphone box, that is, first execute S1107, and then execute 1106.

[0196] In another embodiment, there is no actual order between S1106 and S1107, and they can be performed simultaneously.

[0197] S1108, the headphone case has stopped receiving audio signals.

[0198] When the headphone case detects that both left and right earbuds are inside the case or the first timer expires, the headphone case can stop receiving audio signals.

[0199] Optionally, in response to the user opening the case, before the earphone case starts its first timer, such as... Figure 11 As shown in (b) above, the method may further include:

[0200] S1110, the earphone case determines whether both left and right wireless earphones are inside the earphone case.

[0201] In response to the user's opening of the case, the earphone case can detect whether both left and right wireless earphones are inside the case. When both left and right wireless earphones are inside the case, step S1109 is executed; when at least one of the left and right wireless earphones is not inside the case, step S1102 is executed.

[0202] In this embodiment, the wireless earphone can send an audio signal when preset conditions are met. During the process of the user inserting the wireless earphone into the earphone case, the earphone case can receive the audio signal sent by the wireless earphone. The earphone case can light up the insertion indicator light to indicate to the user that it is inserted into the correct storage compartment, which improves efficiency and user experience. A first timer is set in the earphone case to control the time for the earphone case to receive the audio signal, thus avoiding wasting the earphone case's power.

[0203] Figure 12 A schematic flowchart illustrating a method for indicating when wireless earphones are inserted into their case, as provided in an embodiment of this application, is shown. This method can be executed by a system comprising a first wireless earphone and an earphone case. The earphone case includes a first insertion indicator light, and the first wireless earphone and the first insertion indicator light have a corresponding relationship. Figure 12 As shown, the process includes:

[0204] S1201, the first wireless earphone sends a first signal in response to detecting that a first preset condition is met.

[0205] The first wireless earphone can send a first signal when the first preset conditions are met.

[0206] In one embodiment, the first wireless earphone may be either a left wireless earphone or a right wireless earphone.

[0207] In one embodiment, if the first wireless earphone is the left wireless earphone, the first insertion indicator light can be the insertion indicator light corresponding to the left wireless earphone on the earphone case; if the first wireless earphone is the right wireless earphone, the first insertion indicator light can be the insertion indicator light corresponding to the right wireless earphone on the earphone case.

[0208] For example, the first preset condition may be: the first wireless earphone is not in the earphone case and / or the first wireless earphone is not in the user's ear.

[0209] In one embodiment, when the first wireless earphone uses Bluetooth Low Energy (BLE), the first signal may be a BLE data packet.

[0210] In one embodiment, the first signal may be an audio signal.

[0211] In one embodiment, the first wireless earphone starts a second timer in response to detecting that a first preset condition is met, and during the operation of the second timer, the first wireless earphone sends a first signal.

[0212] In one embodiment, when the second timer runs for a period of time greater than a second threshold, the first wireless earphone stops transmitting the first signal.

[0213] S1202, the earphone box receives the first signal.

[0214] In one embodiment, the earphone case receives the first signal when it meets a second preset condition.

[0215] In one embodiment, when the earphone box meets a second preset condition, a first timer is started, and during the operation of the first timer, the first earphone box receives a first signal.

[0216] For example, the second preset condition could be: the headphone case detects that the first wireless earphone is not inside the headphone case and the headphone case detects that the user has opened the headphone case lid.

[0217] For example, the second preset condition could be: the headphone case detects that the user has opened the headphone case lid.

[0218] In one embodiment, when the earphone box does not receive the first signal and the first timer runs for a period of time greater than a first threshold, the earphone box stops receiving the first signal.

[0219] S1203, the earphone case illuminates the first insertion indicator light based on the first signal.

[0220] The earphone case can light up the first insertion indicator light based on the first signal. There is a corresponding relationship between the first signal and the first insertion indicator light. When the earphone case receives the first signal, it can light up the first insertion indicator light.

[0221] In one embodiment, the first signal is an audio signal with a first frequency. The headphone box can determine that it has received an audio signal of the first frequency and illuminate the first insertion indicator light.

[0222] For example, the first wireless earphone is the left wireless earphone, and the frequency of the audio signal transmitted by the left wireless earphone can be 20kHz. The system may also include a second wireless earphone, which can be the right wireless earphone, and the frequency of the audio signal transmitted by the right wireless earphone can be 22kHz. In this way, the earphone case can determine whether the audio signal is from the left or right wireless earphone based on the frequency of the audio signal, and thus illuminate the corresponding insertion indicator light.

[0223] In one embodiment, the first signal is an audio signal, which is transmitted by the first wireless earphone in a first cycle. The earphone case can determine that it has received the audio signal in the first cycle and illuminate the first insertion indicator light.

[0224] For example, the first wireless earphone is the left wireless earphone, and the audio signal transmitted by the left wireless earphone can have a cycle of 1 second transmission, 1 second pause, and so on. The system may also include a second wireless earphone, which can be the right wireless earphone, and the audio signal transmitted by the right wireless earphone can have a cycle of 2 seconds transmission, 2 seconds pause, and so on. In this way, the earphone case can determine whether the audio signal is from the left or right wireless earphone based on the transmission cycle of the audio signal, and thus illuminate the corresponding insertion indicator light.

[0225] In one embodiment, the earphone case includes a second insertion indicator light, which corresponds to a second signal. When the earphone case simultaneously receives a first signal sent by a first wireless earphone and a second signal sent by a second wireless earphone, the earphone case can determine the wireless earphone that is closer to the earphone case between the first and second wireless earphones based on the signal strength of the received first and second signals. Thus, the earphone case can light up the insertion indicator light corresponding to the wireless earphone that is closer to it.

[0226] For example, when the signal strength of the first signal transmitted by the first wireless earphone is greater than the signal strength of the second signal transmitted by the second wireless earphone, the earphone case can determine that the distance between the first wireless earphone and the earphone case is less than the distance between the second wireless earphone and the earphone case, and thus the earphone case can illuminate the first insertion indicator light. For example, when the first signal and the second signal are audio signals, the signal strength of the first signal and the second signal can be sound intensity.

[0227] In this embodiment, during the insertion of the wireless earphones into the earphone case, the earphone case can receive audio signals sent by the wireless earphones, and the earphone case can light up the insertion indicator light to indicate to the user that the earphones are inserted into the correct storage compartment, thereby improving efficiency and user experience. The earphone case is equipped with a first timer to control the time for the earphone case to receive audio signals, thus avoiding wasting the earphone case's power. The wireless earphones are equipped with a second timer to control the time for the wireless earphones to send audio signals, thus avoiding wasting the wireless earphones' power.
