Description

Headphone left and right channel matching method, ear clip-on headphone and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 28, 2024, application number 202410371075.4, and application name "Headphone left and right channel matching method, ear clip-on headphones and storage medium", all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of earphone technology, and in particular to a method for matching left and right sound channels of an earphone, an earclip earphone, and a storage medium. Background Art

[0003] With the development of new technologies, OWS (Open Wearable Stereo) headphones, such as clip-on earphones, are becoming increasingly popular. Compared to TWS (True Wireless Stereo) headphones, clip-on earphones are more ear-friendly, hearing-safe, comfortable to wear, and more suitable for extended wear. Because clip-on earphones don't need to be worn in the ear, they can be worn in both ears, ensuring a consistent fit and a universal fit, unlike traditional earphones.

[0004] Ear clip headphones have a left earphone and a right earphone. The left earphone outputs the left channel, while the right earphone outputs the right channel. When the stereo headphones are worn, the left earphone contacts the user's left ear, while the right earphone contacts the user's right ear, allowing the left ear to hear the left channel and the right ear to hear the right channel. During wear, the relative positions of the left and right earphones cannot be interchanged, as doing so will directly affect the fidelity of the sound source and the resolution of the audio frequencies.

[0005] To achieve perfect sound quality, users must first identify the left and right sides of their ear clips before putting them on. The current solution is to mark the ear clips with symbols such as L / R, but this requires manual verification to ensure they are not worn incorrectly, which is inconvenient for the user.

[0054] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0055] Ear clip headphones have a left earphone and a right earphone. The left earphone outputs the left channel, while the right earphone outputs the right channel. When the stereo headphones are worn, the left earphone contacts the user's left ear, while the right earphone contacts the user's right ear, allowing the left ear to hear the left channel and the right ear to hear the right channel. During wear, the relative positions of the left and right earphones cannot be interchanged, as doing so will directly affect the fidelity of the sound source and the resolution of the audio frequencies.

[0056] To achieve perfect sound quality, users must first identify the left and right sides of their ear clips before putting them on. The current solution is to mark the ear clips with symbols such as L / R, but this requires manual verification to ensure they are not worn incorrectly, which is inconvenient for the user.

[0057] Example 1

[0058] Based on this, please refer to Figure 1, which is a flow chart of a first embodiment of the headphone left and right channel matching method of the present application. The headphone left and right channel matching method is applied to ear clip-on headphones. The target earphone of the ear clip-on headphones is provided with a three-axis acceleration sensor and a fingerprint sensor. The method includes:

[0059] Step S10: upon detecting that the target earphone is worn, obtaining three-axis acceleration information detected by the three-axis acceleration sensor and a sensed fingerprint detected by the fingerprint sensor, wherein the target earphone is the first earphone or the second earphone in the ear clip-on earphone;

[0060] As those skilled in the art will appreciate, an earphone-style headset comprises two individual earphones, namely a first earphone and a second earphone. As shown in Figures 3 and 4, Figure 3 shows an earphone-style headset according to an embodiment of the present application from one perspective, and Figure 4 shows an earphone-style headset according to an embodiment of the present application from another perspective. A single earphone comprises a speaker compartment 3 and a behind-the-ear compartment 1, as well as a connecting bridge 2 connecting the speaker compartment and the behind-the-ear compartment. The speaker compartment area refers to the area corresponding to the speaker compartment 3. As those skilled in the art will appreciate, for earphones, the speaker compartment 3 is typically provided with an acoustic module, which includes a speaker. Of course, the acoustic module may also include a microphone, but this is not specifically limited in this embodiment. The behind-the-ear compartment 1 is typically provided with a power module for providing electrical energy. Of course, the behind-the-ear compartment 1 may also be provided with a noise reduction module and a communication module, etc., but this is not specifically limited in this embodiment. The speaker is used to play audio from the left or right channel, and the power module is used to provide electrical energy to the single earphone. The communication module is used to enable the single earphone to communicate with other electronic devices connected to the single earphone for information exchange. The accelerometer is used to detect the three-axis acceleration information of the earphone. The microphone is used to collect ambient audio, and the noise reduction module is used to perform adaptive noise reduction on the ambient audio collected by the microphone based on a preset noise reduction algorithm. The preset noise reduction algorithm can be an ANC (Active Noise Control) noise reduction algorithm, an ENC (Environmental Noise Cancellation) noise reduction algorithm, a DSP (digital signal processing) noise reduction algorithm, or a CVC (Clear Voice Capture) noise reduction algorithm. Those skilled in the art have conducted in-depth research on these noise reduction algorithms and will not be elaborated on here.

[0061] In this embodiment, the hardware principle of the fingerprint sensor has been deeply studied by those skilled in the art and will not be described in detail here.

[0062] Those skilled in the art will know that a three-axis acceleration sensor works based on the basic principle of acceleration, and acceleration is a space vector.

[0063] Step S20: adjusting the sound channel of the speaker of the target headset according to the three-axis acceleration information and the sensed fingerprint, so that the sound channel of the target headset matches the wearing position.

[0064] Exemplarily, adjusting the sound channel of the speaker of the target headset according to the three-axis acceleration information and the sensing fingerprint includes:

[0065] Step A10: determining a wearing position corresponding to the target headset based on the three-axis acceleration information and the sensed fingerprint;

[0066] Step A20: Based on the wearing position corresponding to the target earphone, adjust the channels of the speaker of the target earphone so that the left channel corresponds to the earphone worn at the left ear position, and / or the right channel corresponds to the earphone worn at the right ear position.

[0067] In this embodiment, the skin texture, including fingerprints, on each finger of a person's left and right hands differs in pattern, breakpoints, and intersections, making it unique and unchanging throughout life. Therefore, the fingerprints of each finger on the user's left and right hands can be associated with the left and right hands. By comparing each finger's fingerprint with the fingerprint data stored in the user's left and right hand correspondence, the left and right hands can be determined. This is known as fingerprint recognition technology.

[0068] Among them, the fingerprint sensor can be a miniaturized fingerprint recognition module, which is set at the contact part of the earphone when the user pinches the earphone when picking up the earphone. Since the fingerprint sensor does not involve security issues, it only needs to roughly judge the finger features and does not require a standard fingerprint recognition unit. It can be implemented in a relatively small structural space inside the earphone.

[0069] In this embodiment, when the left and right channels of the target headset are initialized, the fingerprint sensor of the target headset may use fingerprint recognition technology to scan at least one finger on each of the user's left and right hands to collect fingerprint information. For example, the fingerprint sensor may scan at least one finger on the left hand, such as at least one of the thumb, index finger, middle finger, ring finger, and pinky finger. For ease of use, the fingerprint sensor preferably scans fingerprints on the thumbs and / or index fingers of both hands. The fingerprint sensor then inputs the scanned fingerprint information into the processor of the target headset. The processor inputs the fingerprint information to a display device communicatively connected to the headset. The display device displays left and right channel selection options, such as "Detecting fingerprint information, do you want to store it as left channel information?" or "Detecting fingerprint information, do you want to store it as right channel information?", for the user to select. The processor receives the left and right channel selection result and inputs the left and right channel selection result, as well as the correspondence between the left and right channels and the fingerprint, or the correspondence between the left and right channels and the left and right hands, into the headset's memory.

[0070] Preferably, each finger of the left and right hands of the user is initialized. After the initialization of the left and right channels of the earphones is completed, when the user uses the earphones, before the earphones are worn, when any finger of any hand pinches the target earphone, the fingerprint sensor collects the fingerprint information of the current user (i.e., the sensed fingerprint) and inputs it to the processor, and then the processor is used to configure the speaker corresponding to the target earphone to the left channel or the right channel according to the sensed fingerprint collected during use and the correspondence between the left channel and the right channel and the fingerprint stored in the memory. In another embodiment of the present invention, the processor can also be used to determine whether the current finger is a left hand finger or a right hand finger according to the sensed fingerprint collected during use, and then configure the speaker corresponding to the target earphone to the left channel or the right channel according to the correspondence between the left and right channels and the left and right hands stored in the memory.

[0071] In this embodiment, different fingerprints are collected each time the earphones are worn to achieve automatic matching of the left and right channels with the left and right ears, thereby achieving the purpose of arbitrary wearing. That is, when the user takes off the target earphones to wear them, any finger of any hand will pinch the surface of the target earphones. It is easy to understand that according to wearing habits, the left earphone is generally worn on the left hand and the right earphone is worn on the right hand. Therefore, the fingerprint sensor provided on the target earphone can collect the fingerprint information of the current user and input it to the processor. The processor is used to configure the speaker corresponding to the target earphone to the left channel or the right channel based on the correspondence between the fingerprint information and the left and right channels and the fingerprint information of the current finger used. Specifically, when the current user's sensed fingerprint is the left hand fingerprint, the speaker corresponding to the target earphone is configured to the left channel. When the current user's sensed fingerprint is the right hand fingerprint, the speaker corresponding to the target earphone is configured to the right channel.

[0072] It should be noted that if only the three-axis acceleration sensor is used to detect the three-axis acceleration information of the target headset, and the corresponding wearing position of the target headset is determined based on the three-axis acceleration information, for example, if the component of the three-axis acceleration information in the vertical direction points to the positive direction of the Z axis, then the wearing posture information corresponding to the target headset is determined to be the first posture, and if the component of the three-axis acceleration information in the vertical direction points to the negative direction of the Z axis, then the wearing posture information corresponding to the target headset is determined to be the second posture, and then if the wearing posture information is the first posture, then the corresponding wearing position of the target headset is determined to be the left ear wearing position;

[0073] If the wearing posture information is the second posture, the target earphone is determined to be in the right ear wearing position. Based on the corresponding wearing positions of the first earphone and the second earphone, the left and right channels of the earclip earphone's speaker are adjusted so that the left channel corresponds to the earphone in the left ear wearing position. However, the process of identifying the wearing position of the target earphone using only the three-axis acceleration sensor may result in misjudgment due to some special scenarios. For example, when a person wears the earphones, their head is not upright, but in an unconventional posture such as inverted or lying down. In this case, the target earphone's wearing position cannot be accurately identified. In particular, when the head is in an inverted position, the identified wearing position is exactly the opposite, resulting in misidentification.

[0074] Based on this, the embodiment of the present application integrates the acceleration sensor information and the sensing fingerprint information of the target earphones, so that the user can wear the earphones in any posture and can detect them correctly and autonomously. The left and right ear channels will no longer change due to changes in the user's head movements, further improving the stability and robustness of the left and right channel matching method of the earphones in the embodiment of the present application.

[0075] Exemplarily, the target earphone includes a speaker chamber and a behind-the-ear chamber, and the fingerprint sensor includes a fingerprint detection sensing strip for fingerprint area sensing, and the fingerprint detection sensing strip is arranged on the surface of the speaker chamber and / or behind-the-ear chamber.

[0076] In this embodiment, as shown in FIG4 , the target earphone includes a speaker chamber 3 and a behind-the-ear chamber 1, and a connecting bridge 2 connecting the speaker chamber 3 and the behind-the-ear chamber 1. The speaker chamber area refers to the area corresponding to the speaker chamber 3. It is known to those skilled in the art that, for ear clip-on earphones, an audio output unit is generally provided in the speaker chamber 3, and a communication unit and a power storage unit are generally provided in the behind-the-ear chamber 1 (for example, the behind-the-ear chamber 1 or the speaker chamber 3 may also be provided with a noise reduction unit, etc.). The fingerprint detection sensor strip is provided on the surface of the speaker chamber 3 and / or the behind-the-ear chamber 1.

[0077] The embodiment of the present application provides an open-ear headphone that does not require the user to distinguish between the left and right ears when worn, and the headphone can independently identify the left and right channels when worn, thereby avoiding the trouble of the user having to distinguish between the left and right ears when wearing.

[0078] Exemplarily, the first earphone and the second earphone are further provided with a capacitive touch sensor, and the method further includes:

[0079] Step B10, acquiring capacitance sensing information detected by the capacitive touch sensor;

[0080] Step B20: Detecting whether the ear clip earphone is worn according to the capacitive sensing information.

[0081] The present application obtains capacitance sensing information detected by a capacitive touch sensor, and accurately detects whether the ear clip earphones are worn based on the capacitance sensing information.

[0082] In a possible implementation, determining the wearing position corresponding to the target headset according to the three-axis acceleration information and the sensed fingerprint includes:

[0083] Step C10, determining the vertical component direction of the three-axis acceleration information;

[0084] Step C20, performing fingerprint matching on the sensed fingerprint in a pre-stored fingerprint database to obtain a matching fingerprint corresponding to the sensed fingerprint, and determining fingerprint registration information associated with the matching fingerprint;

[0085] Exemplarily, performing fingerprint matching on the sensed fingerprint in a pre-stored fingerprint database to obtain a matching fingerprint corresponding to the sensed fingerprint includes:

[0086] Step D10, matching the sensed fingerprint with registered fingerprints in a pre-stored fingerprint database;

[0087] Step D20: After the feature matching rate between the registered fingerprint and the sensing fingerprint is greater than a preset ratio threshold, the registered fingerprint having the feature matching rate greater than the preset ratio threshold is used as the matching fingerprint corresponding to the sensing fingerprint.

[0088] After step C20, step C30 is executed to determine the touching hand information to which the sensed fingerprint belongs based on the fingerprint registration information;

[0089] Step C40: determining the wearing position corresponding to the target headset according to the fingerprint registration information and the touching hand information.

[0090] Exemplarily, determining the wearing position corresponding to the target headset according to the fingerprint registration information and the touching hand information includes:

[0091] Step D10: If the touching hand information is the left hand, and the vertical component of the three-axis acceleration information points to the positive direction of the Z axis, then determining that the wearing position corresponding to the target headset is the left ear;

[0092] Step D20: If the touching hand information is the right hand, and the vertical component of the three-axis acceleration information points to the negative direction of the Z axis, it is determined that the wearing position corresponding to the target earphone is the right ear.

[0093] In this embodiment, the preset ratio threshold can be set by those skilled in the art according to actual conditions and is not specifically limited in this embodiment. For example, the preset ratio threshold can be 95% or 98%.

[0094] The embodiment of the present application determines the component direction of the three-axis acceleration information in the vertical direction, and matches the sensed fingerprint in a pre-stored fingerprint database to obtain a matching fingerprint corresponding to the sensed fingerprint, and determines the fingerprint registration information associated with the matching fingerprint. Then, based on the fingerprint registration information, the touch hand information to which the sensed fingerprint belongs is determined, and then based on the fingerprint registration information and the touch hand information, the wearing position corresponding to the target earphone is determined, thereby effectively improving the accuracy of identifying the wearing position of the earphone, and automatically matching the left and right channels with the left and right ears by having the left channel of the earphone correspond to the wearing position of the left ear, and the right channel of the earphone correspond to the wearing position of the right ear, thereby overcoming the inconvenience caused by marking labels such as L / R on the earphone in the related art, which requires manual confirmation to ensure that the earphone is not worn incorrectly, thereby improving the convenience of using ear-clip earphones.

[0095] Example 2

[0096] Based on the first embodiment of the present application, in another embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction and will not be described in detail later. On this basis, the method further includes:

[0097] Step E10: When the touching hand information indicates a right hand and the vertical component of the three-axis acceleration information points in the positive direction of the Z axis, or when the touching hand information indicates a left hand and the vertical component of the three-axis acceleration information points in the negative direction of the Z axis, determining the vertical component value of the three-axis acceleration information;

[0098] Step E20: Determine the wearing position corresponding to the target earphone according to the component direction and the component value.

[0099] Exemplarily, determining the wearing position corresponding to the target headset according to the component orientation and the component value includes:

[0100] Step F10: If the vertical component of the three-axis acceleration information points to the positive direction of the Z axis and the component value matches the gravity acceleration value, then determining that the wearing position corresponding to the target earphone is the left ear;

[0101] Step F20: If the vertical component of the three-axis acceleration information points to the negative direction of the Z axis and the component value matches the gravity acceleration value, it is determined that the wearing position corresponding to the target earphone is the right ear.

[0102] In this embodiment, it is known to those skilled in the art that, since a person's head is generally in an upright position when wearing headphones (the head is rarely lying down or upside down), the component value in the Z-axis direction generally matches the gravity acceleration value. Based on this principle, the embodiment of the present application determines that the target headphone's corresponding wearing position is the left ear when the component corresponding to the three-axis acceleration information of the target headphone points to the positive direction of the Z axis and the component value in the positive direction of the Z axis matches the gravity acceleration value; and if the component corresponding to the three-axis acceleration information of the target headphone points to the negative direction of the Z axis and the component value in the negative direction of the Z axis matches the gravity acceleration value, the target headphone's corresponding wearing position is determined to be the right ear, thereby further improving the accuracy of identifying the headphone wearing position, and automatically matching the left and right channels with the left and right ears by using the left channel corresponding to the left ear wearing position of the headphone and the right channel corresponding to the right ear wearing position of the headphone, further determining that there is no need to distinguish between the left and right channels before wearing the headphones, and no matter how the ear clip headphones are worn, the sound signals of the left and right channels obtained are always correct.

[0103] In an practicable manner, after determining the component value of the three-axis acceleration information in the vertical direction, the method further includes:

[0104] Step G10: If the component value matches the gravity acceleration value, executing: the step of determining the wearing position corresponding to the target headset according to the component direction and the component value;

[0105] Step G20: If the component value does not match the gravity acceleration value, determine the wearing position corresponding to the reference earphone; and determine the wearing position corresponding to the target earphone based on the wearing position corresponding to the reference earphone, wherein the reference earphone is an earphone of another channel in the ear-clip earphone corresponding to the target earphone.

[0106] Exemplarily, determining the wearing position corresponding to the target earphone according to the wearing position corresponding to the reference earphone includes:

[0107] Step H10: If the reference earphone is worn on the left ear, determine that the target earphone is worn on the right ear.

[0108] Step H20: If the wearing position corresponding to the reference earphone is the right ear, determine that the wearing position corresponding to the target earphone is the left ear.

[0109] Since it is possible that even if one earphone is integrated with the acceleration sensor information and the fingerprint sensor information, it is still impossible to effectively detect the wearing posture information of the target earphone (for example, a special factor such as a sensor failure of a certain earphone occurs), the wearing posture of the other earphone can be combined to assist in determining the current wearing posture of the target earphone. It is easy to understand that when both earphones are in the wearing state, if one earphone is worn on the left ear, the other earphone must be worn on the right ear, and if one earphone is worn on the right ear, the other earphone must be worn on the left ear.

[0110] Based on this, the embodiment of the present application determines the wearing posture information corresponding to the reference earphone when the component value does not match the gravitational acceleration value, and determines the wearing posture information corresponding to the target earphone based on the wearing posture information corresponding to the reference earphone, wherein the reference earphone is the earphone of another channel corresponding to the target earphone in the ear-clip earphone, so that even if the acceleration sensor information and the sensing fingerprint information are integrated with a certain earphone, the wearing posture of the target earphone cannot be effectively detected, and the wearing position of the earphone can be accurately identified, so that the left channel can be matched with the left ear wearing position of the earphone, and the right channel can be matched with the right ear wearing position of the earphone, so as to further ensure that the left and right channels are accurately and automatically matched with the left and right ears.

[0111] In order to further help understand the technical concept of this application, a specific embodiment is listed, including:

[0112] As shown in Figure 2, Figure 2 is a schematic diagram of the wearing posture of the ear clip type earphones in a wearing state at one viewing angle (looking down from the top of the head). The two earphone units of the first earphone and the second earphone are the same, and there is no need to manually distinguish between the left and right ears, and the user can wear them at will. The earphones will automatically distinguish and configure the left and right channels according to the left and right sides of the user. Since the user's head is generally in an upright upward position when just wearing it, rather than a lying or inverted position, the left and right channel matching method of the earphones of the embodiment of the present application can easily implement an autonomous detection scheme for the left and right channels of open earphones, which is convenient for users to wear and use. Users no longer need to distinguish between left and right, and can wear them blindly. In addition, the ear clip type earphones of the embodiment of the present application have a simple structure, and the hardware cost of implementing the left and right channel matching method of the earphones is low.

[0113] In one embodiment, an acceleration sensor can be provided in the compartment behind the ear, and the coordinates can be calibrated according to the normal wearing posture when the headset leaves the factory. For example, the same coordinate calibration is performed on each single earphone, and the Z axis is calibrated to point upwards in the normal wearing posture. It is also defined that when the headset is worn normally, it is detected that the Z axis points upwards as the left channel. Please refer to Figure 5, which is a display diagram of the three-axis acceleration information when the earphones are worn on the left and right ears in the embodiment of the present application, such as the side view schematic diagram when the left ear is worn in Figure 5. When worn, it is detected that the Z axis points downwards as the right channel, such as the side view schematic diagram when the right ear is worn in Figure 5. When the user wears it in the correct posture, the Z axis of one earphone must point upwards and the Z axis of the other earphone must point downwards to complete the left and right channel configuration. After the earphones leave the factory, the left and right channel identification needs to be completed in conjunction with the wearing detection function of the acceleration sensor data of the headset.

[0114] If the user wears the headset in an abnormal posture, such as lying down or standing upside down, relying solely on the acceleration sensor may cause misjudgment and fail to accurately equip the left and right channels.

[0115] This embodiment adds a miniature fingerprint sensor behind the ear. When using the product for the first time, users need to register both left and right fingerprints for each earbud. The fingerprint sensor's fingerprint detection strip is located where the user's fingers can easily pick up the product when removing it from the charging case. This allows for fingerprint recognition of both hands while the user is picking up the earbuds.

[0116] According to wearing habits, the left earphone is usually worn on the left hand and the right earphone is worn on the right hand. For ear clip earphones, it is difficult to wear the earphone on the left hand or the left earphone on the right hand.

[0117] At this time, from taking the earphones out of the charging box to wearing them, the acceleration sensor detects the coordinates and recognizes the fingerprint, so that the left and right channels can be correctly configured in any free posture of the user.

[0118] In addition, left and right channel recognition requires the use of the headphone wearing detection function. Recognition is completed only during the wearing process. During the user's wearing and use, the left and right ear channels will no longer change due to changes in the user's head movement.

[0119] It should be noted that this specific embodiment is only used to understand the technical concept of this application and does not constitute a limitation of this application. More simple forms of transformation based on the technical concept of this application should all be within the scope of protection of this application.
