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 202410370106.4, 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Example 1

[0062] Based on this, please refer to Figure 1, which is a flow chart of the 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 ear clip-on headphones include two single headphones, namely a first headphone and a second headphone. The first headphone and the second headphone of the ear clip-on headphones are both provided with a three-axis acceleration sensor, and the speaker chamber area of ​​the first headphone and the speaker chamber area of ​​the second headphone are both provided with a contact sensor. The method includes:

[0063] Step S10: When it is detected that the target earphone is worn, three-axis acceleration information detected by the three-axis acceleration sensor and tactile information detected by the contact sensor are acquired, wherein the target earphone is the first earphone or the second earphone.

[0064] 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.

[0065] In this embodiment, the type of the touch sensor may be a capacitive touch sensor or a resistive touch sensor.

[0066] As shown in Figures 3 and 4, Figure 3 shows the ear-clip earphones according to an embodiment of the present application from one viewing angle, and Figure 4 shows the ear-clip earphones according to an embodiment of the present application from another viewing angle. A single earphone includes 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 ear-clip earphones, the speaker compartment 3 is typically equipped with an acoustic module, which includes a speaker and, of course, may also include a microphone, though this embodiment does not specifically limit this. The behind-the-ear compartment 1 is typically equipped with a power module for providing electrical energy. Of course, the behind-the-ear compartment 1 may also be equipped with a noise reduction module and a communication module, though this embodiment does not specifically limit this. 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 exchange information between the single earphone and other electronic devices to which the single earphone is connected. The acceleration sensor is used to detect triaxial acceleration information of the single 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, etc. For these noise reduction algorithms, those skilled in the art have conducted in-depth research and will not go into details here.

[0067] In this embodiment, the touch sensor is a capacitive touch sensor or a resistive touch sensor. The touch sensor is located in the speaker compartment. Those skilled in the art have conducted extensive research on the hardware principles of capacitive and resistive touch sensors, and will not be elaborated upon here.

[0068] Step S20: determining a tactile distribution position generating a tactile sensation in the speaker chamber area according to the tactile sensation information.

[0069] It is understandable that after the ear-clip earphones are worn, part of the ear-clip earphones will come into contact with the ear part, and since the target earphones are worn on the left ear and then on the right ear, their position will be flipped. That is, if the target earphones are worn on the left ear, the contact area between the target earphones and the left ear is the first area, then, when the target earphones are worn on the right ear, since the position of the target earphones is flipped (about 180 degrees), the contact area between the target earphones and the right ear will change to the second area, and the first area is different from the second area, as shown in Figures 2 and 3, wherein Figure 2 is a schematic diagram of the wearing position of the ear-clip earphones in a wearing state at one viewing angle, and Figure 3 is an ear-clip earphone of an embodiment of the present application at one viewing angle.

[0070] Among them, the mapping relationship between the contact area corresponding to the tactile information (i.e., the tactile distribution position) and the three-axis acceleration information and the wearing position information can be stored in the target earphone in advance, or stored in the cloud server registered and logged in with the target earphone. In one example, the mapping relationship stored in the target earphone or the cloud server registered and logged in with the target earphone is: the contact area corresponding to the tactile information is the first area, and the component of the three-axis acceleration information in the vertical direction points to the positive direction of the Z axis, then the wearing position information mapped by the two is the left ear wearing position. And, the contact area corresponding to the tactile information is the second area, and the component of the three-axis acceleration information in the vertical direction points to the negative direction of the Z axis, then the wearing position information mapped by the two is the right ear wearing position. Based on the stored mapping relationship, it is convenient to subsequently determine the wearing position corresponding to the first earphone according to the three-axis acceleration information and the tactile information.

[0071] Step S30 : adjusting the sound channel of the speaker of the target earphone according to the three-axis acceleration information and the tactile distribution position, so that the sound channel of the target earphone matches the wearing position.

[0072] Exemplarily, the contact sensor includes a touch sensing strip for tactile area sensing, and the touch sensing strip is applied to the speaker chamber area.

[0073] In this embodiment, as shown in Figures 7 and 8, Figure 7 is a structural diagram of the target earphone in an example of the present application, and Figure 8 is a tactile display diagram of the touch sensing band in the wearing scenario of the target earphone in an example of the present application. The target earphone includes a speaker compartment 3 and a behind-the-ear compartment 1, and a connecting bridge 2 connecting the speaker compartment 3 and the behind-the-ear compartment 1. The speaker compartment area refers to the area corresponding to the speaker compartment 3. The touch sensing band sensed by the tactile area is the oblique shaded area in Figures 7 and 8, such as the oblique shaded area marked by a1 and a2 in Figure 7. The area marked by arrow 4 in the touch sensing band in Figure 8, and the concha cavity side where the touch sensing band fits the ear, are both tactile distribution positions.

[0074] An embodiment of the present application discloses a method for matching left and right channels of headphones, an ear-clip headphone, and a storage medium. The method for matching left and right channels of headphones is applied to ear-clip headphones, wherein the first and second earphones of the ear-clip headphone are both provided with a three-axis acceleration sensor, and the speaker chamber area of ​​the first earphone and the speaker chamber area of ​​the second earphone are both provided with a contact sensor. The technical solution of the method for matching left and right channels of headphones of the present application is to obtain three-axis acceleration information detected by the three-axis acceleration sensor and tactile information detected by the contact sensor when detecting that the target earphone is worn, wherein the target earphone is the first earphone or the second earphone, and based on the tactile information, determine the tactile distribution that generates the tactile sensation in the speaker chamber area The three-axis acceleration information and the tactile distribution position are then used to adjust the sound channels of the target earphones' speakers so that the sound channels of the target earphones match the wearing position, so that the left channel corresponds to the earphones worn at the left ear, and the right channel corresponds to the earphones worn at the right ear, thereby achieving automatic matching of the left and right channels with the left and right ears. This overcomes the inconvenience caused by marking labels such as L / R on the earphones in the related art, which requires manual confirmation to ensure that they are not worn upside down. This improves the ease of use of ear-clip earphones and effectively eliminates the need for users to distinguish between left and right channels before wearing the earphones. That is, no matter how the ear-clip earphones are worn, the sound signals of the left and right channels obtained are always correct, thereby improving the user's hearing effect.

[0075] It is worth mentioning that if only the three-axis acceleration sensor is used to detect the three-axis acceleration information of the target headset, and the wearing position corresponding to the target headset is determined according to 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 wearing position corresponding to the target headset is determined to be the left ear wearing position;

[0076] 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.

[0077] Based on this, the embodiment of the present application integrates the acceleration sensor information and tactile information of the target earphones (the tactile information is specifically the tactile distribution position), 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.

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

[0079] Step A10, acquiring capacitance sensing information detected by the capacitive touch sensor;

[0080] Step A20: 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] Exemplarily, adjusting the sound channel of the speaker of the target headset according to the three-axis acceleration information and the tactile distribution position includes:

[0083] Step B10, determining a wearing position corresponding to the target headset according to the three-axis acceleration information and the tactile distribution position;

[0084] Step B20: Based on the wearing position corresponding to the target headset, adjust the channels of the speaker of the target headset so that the left channel corresponds to the headset in the left ear wearing position, and / or the right channel corresponds to the headset in the right ear wearing position.

[0085] As shown in Figure 2, Figure 2 is a schematic diagram of the wearing posture of the ear clip-on earphones in the embodiment of the present application 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. Regardless of the posture of the user's head when wearing, including an upright posture, a lying posture, and an inverted posture, the left and right channel matching method of the earphones in the embodiment of the present application can be used to implement an autonomous detection scheme for the left and right channels of open-type 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, effectively ensuring the stability and robustness of the left and right channel matching method of the earphones in the embodiment of the present application.

[0086] 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. As shown in the side view diagram of the left ear when worn in Figure 5. When worn, it is detected that the Z axis points downwards as the right channel, as shown in the side view diagram of the right ear when 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.

[0087] The embodiment of the present application determines the corresponding wearing position of the target earphone according to the three-axis acceleration information and the tactile distribution position, and then adjusts the sound channel of the speaker of the target earphone based on the corresponding wearing position of the target earphone, so that the left channel corresponds to the earphone worn at the left ear, and / or the right channel corresponds to the earphone worn at the right ear, thereby achieving automatic matching of the left and right channels with the left and right ears, 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, and improving the convenience of using ear clip earphones.

[0088] In a possible implementation, the speaker chamber area includes a first area and a second area disposed opposite each other, and determining a wearing position corresponding to the target earphone according to the three-axis acceleration information and the tactile distribution position includes:

[0089] Step C10, determining the vertical component direction of the three-axis acceleration information;

[0090] Step C20, determining a first tactile area corresponding to the tactile distribution position in the first region, and a second tactile area corresponding to the second region;

[0091] Step C30: determining wearing posture information corresponding to the target headset according to the first tactile area, the second tactile area, and the component orientation;

[0092] Exemplarily, determining the wearing posture information corresponding to the target headset according to the first tactile sensing area, the second tactile sensing area, and the component orientation includes:

[0093] Step D10: If the first tactile area is larger than the second tactile area, and the vertical component of the three-axis acceleration information points to the positive direction of the Z axis, determining that the wearing posture information corresponding to the target headset is the first posture;

[0094] Step D20: If the first tactile area is smaller than the second tactile area, 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 posture information corresponding to the target headset is the second posture.

[0095] After step C30 , step C40 is executed to determine the wearing position corresponding to the target headset according to the wearing posture information.

[0096] The first touch sensitive area refers to the touch sensitive area corresponding to the first region, and the second touch sensitive area refers to the touch sensitive area corresponding to the second region.

[0097] In this embodiment, the position of the target earphone is reversed when it is worn on the left ear and then on the right ear. That is, if the target earphone is worn on the left ear, the main contact area of ​​the target earphone with the left ear is the first area, that is, the first tactile area corresponding to the first area of ​​the tactile distribution position is larger than the second tactile area corresponding to the second area. When the target earphone is worn on the right ear, the position of the target earphone is reversed (approximately 180 degrees), and the main contact area of ​​the target earphone with the right ear will change to the second area, and the first area and the second area are different. That is, the first tactile area corresponding to the first area of ​​the tactile distribution position is larger than the second tactile area corresponding to the second area, and then the first tactile area is smaller than the second tactile area. To facilitate understanding, please refer to Figure 7, which shows two single-unit earphones (i.e., the first earphone and the second earphone). The structures of the two single-unit earphones are exactly the same. One single-unit earphone A shows the first area a1, and the other single-unit earphone B shows the second area a2. The first area a1 and the second area a2 are arranged opposite to each other on the surface area of ​​the speaker chamber 3 to form a covering tendency for the speaker chamber 3.

[0098] Among them, the mapping relationship between the tactile distribution position of the tactile information and the three-axis acceleration information and the wearing position information can be stored in the target headset in advance, or stored in the cloud server registered and logged in with the target headset. In one example, the mapping relationship stored in the target headset or the cloud server registered and logged in with the target headset is: if the first tactile area is larger than the second tactile area, and the component of the three-axis acceleration information in the vertical direction points to the positive direction of the Z axis, then the wearing position information mapped by the two is the left ear wearing position. And, if the first tactile area is smaller than the second tactile area, and the component of the three-axis acceleration information in the vertical direction points to the negative direction of the Z axis, then the wearing position information mapped by the two is the right ear wearing position. Based on the stored mapping relationship, it is convenient to subsequently determine the corresponding wearing position of the first headset according to the three-axis acceleration information and the tactile distribution position.

[0099] 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.

[0100] Exemplarily, determining the wearing position corresponding to the target headset according to the wearing posture information includes:

[0101] Step E10: If the wearing posture information is the first posture, determining that the wearing position corresponding to the target earphone is the left ear wearing position;

[0102] Step E20: If the wearing posture information is the second posture, determine that the wearing position corresponding to the target earphone is the right ear wearing position.

[0103] In this embodiment, the first posture and the second posture are different. It is understood that the second posture is a 180-degree flip, or a near 180-degree flip, of the first posture. In one example, referring to FIG5 , the left image shows the first posture corresponding to when the target earphone is worn on the left ear, and the right image shows the second posture corresponding to when the target earphone is worn on the right ear. The target earphone is either the first earphone or the second earphone.

[0104] The embodiment of the present application determines that the wearing position corresponding to the target earphone is the left ear wearing position when the wearing posture information is the first posture, and determines that the wearing position corresponding to the target earphone is the right ear wearing position when the wearing posture information is the second posture, 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 through the earphone whose left channel corresponds to the left ear wearing position and the earphone whose right channel corresponds to the right ear wearing position, so that there is no need to distinguish between the left and right channels before wearing the earphones, that is, no matter how the ear clip earphones are worn, the sound signals of the left and right channels obtained are always correct.

[0105] Example 2

[0106] 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:

[0107] Step F10: When the first tactile sensing area is smaller than the second tactile sensing area and the vertical component of the three-axis acceleration information points in the positive direction of the Z axis, or when the first tactile sensing area is larger than the second tactile sensing area 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;

[0108] Step F20: Determine the wearing posture information corresponding to the target headset according to the component orientation and the component value.

[0109] Exemplarily, determining the wearing posture information corresponding to the target headset according to the component orientation and the component value includes:

[0110] Step G10: 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 posture information corresponding to the target headset is the first posture;

[0111] Step G20: 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 posture information corresponding to the target headset is the second posture.

[0112] 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 wearing posture information corresponding to the target headset is the first posture when the component corresponding to the three-axis acceleration information of the target headset 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 headset 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 wearing posture information corresponding to the target headset is determined to be the second posture, thereby further improving the accuracy of identifying the wearing position of the headset, and automatically matching the left and right channels with the left and right ears by using the headset with the left channel corresponding to the left ear wearing position and the headset with the right channel corresponding to the right ear wearing position, further determining that there is no need to distinguish between the left and right channels before wearing the headset, and no matter how the ear clip headset is worn, the sound signals of the left and right channels obtained are always correct.

[0113] In an practicable manner, after determining the component value of the three-axis acceleration information in the vertical direction, the method further includes:

[0114] Step H10: If the component value matches the gravity acceleration value, executing: the step of determining the wearing posture information corresponding to the target headset according to the component direction and the component value;

[0115] Step H20: If the component value does not match the gravitational acceleration value, determine the wearing posture information corresponding to the reference earphone; and determine 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 in the ear-clip earphone corresponding to the target earphone.

[0116] Exemplarily, determining the wearing posture information corresponding to the target headset according to the wearing posture information corresponding to the reference headset includes:

[0117] Step I10: If the wearing posture information corresponding to the reference headset is the second posture, determining the wearing posture information corresponding to the target headset is the first posture;

[0118] Step I20: If the wearing posture information corresponding to the reference earphone is the first posture, determine that the wearing posture information corresponding to the target earphone is the second posture.

[0119] Since it is possible that even if one earphone is integrated with the acceleration sensor information and the touch 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 in one 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.

[0120] 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 tactile 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 corresponds to the left ear wearing position of the earphone, and the right channel corresponds to 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.

[0121] In order to further help understand the technical concept of this application, a specific embodiment is listed, including:

[0122] As shown in Figure 2, Figure 2 is a schematic diagram of the wearing posture of the ear clip-on earphones in the embodiment of the present application 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 in 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-on earphones in 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.

[0123] 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, the left channel is detected when the Z axis points upwards, as shown in the side view diagram when the headset is worn on the left ear in Figure 5. When worn, the right channel is detected when the Z axis points downwards, as shown in the side view diagram when the headset is worn on the right ear in Figure 5. When the user wears the headset in the correct posture, the Z axis of one earphone must point upwards and the Z axis of the other earphone must point downwards, completing the left and right channel configuration. After the headset-type headset leaves 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.

[0124] 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.

[0125] To solve the problem of users wearing the headphones in different postures, the headphones can accurately identify and configure the left and right channels, and add contact sensors in the speaker compartment.

[0126] FIG6 is a schematic diagram of a user wearing a target headset in an embodiment of the present application, where B represents a speaker compartment and C represents a C-shaped connecting bridge.

[0127] The oblique shaded area of ​​the speaker compartment in Figure 7 represents the touch sensing band area of ​​the contact sensor, which is applied to the shaded annular area. Please refer to Figure 8, which is a tactile display diagram of the touch sensing band of the target earphone wearing scenario in an example of the present application. When the earphone is worn, the bottom of the speaker compartment contacts the lower bulge of the inner contour of the ear, that is, the area marked by 4 in Figure 8. Since there is no skin contact on the upper part of the speaker compartment, no touch signal (i.e., tactile information) is detected. Similar to the definition of the acceleration sensor coordinates, this case is defined as the left channel. When the contact sensor detects a touch signal on the upper part of the speaker compartment in Figure 8 and no touch signal on the lower part, that is, it is worn on the right ear at this time, it is the right channel. It should be noted that this specific embodiment is only used to understand the technical concept of the present application and does not constitute a limitation of the present application. More simple forms of transformation based on the technical concept of the present application should all be within the scope of protection of the present application.
