Description

Technical Field

[0001] This application relates to the field of headphones, and more particularly to an interaction method and headphones. Background Technology

[0002] Currently, clip-on headphones are designed with the contours and structural features of the human ear in mind. Their unique curvature and shape allow them to fit naturally and snugly on the user's ears, providing a comfortable and imperceptible wearing experience. However, due to the limitations of their structure, clip-on headphones have a smaller interactive surface, and the pursuit of an imperceptible wearing effect presents significant challenges to their interactive features.

[0003] Therefore, how to implement interactive control on clip-on headphones is a problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides an interaction method and headphones that enable interactive control on clip-on headphones, reduce accidental touches, ensure the accuracy of interaction, and further improve the user's interactive experience.

[0005] In a first aspect, an interaction method is provided for headphones, the headphones including a first earphone body, a connecting arm, and a second earphone body, the connecting arm connecting the first earphone body and the second earphone body, the first earphone body being held in the user's concha when the user wears the headphones, and the second earphone body being located outside the user's ear and on a side opposite to the first earphone body, the method including: in response to a user's pressing operation on a target component of the headphones, acquiring a pressure signal, the target component including at least one of the first earphone body, the connecting arm, and the second earphone body; based on the pressure signal, notifying a terminal device to execute a target function instruction; or, executing the target function instruction based on the pressure signal.

[0006] The method can be executed by the headphones, or by a module applied to the headphones (such as a processor, chip, or chip system), or by a logic module or software that can implement all or part of the headphone functions.

[0007] It should be understood that the pressure signal is obtained by converting the physical pressure value measured by the pressure sensor installed on the target component of the headphones.

[0008] Based on the above solution, physical pressure values ​​can be directly measured to trigger corresponding interactive functions. Since the measured value is physical pressure, it is not affected by the user's hair, sweat, or surface dirt, thus effectively reducing the accidental touch rate, improving the accuracy of the interaction, and further enhancing the user's interactive experience.

[0009] It should be noted that the pressure sensor was positioned at a location on the target component that accurately reflects the measured pressure, ensuring that the actual force direction of the pressure sensor aligns with its designed operating direction. This avoids measurement inaccuracies caused by installation deviations. Furthermore, to ensure stability when the user wears the headphones and prevent issues such as loosening or shifting due to pressing, both the specific placement of the pressure sensor on the target component and the user's pressing position were carefully considered.

[0010] In one possible implementation, the first end of the connecting arm is connected to the upper half of the first earphone body, and the sound outlet is located in the lower half of the first earphone body. When the user wears the earphone, the sound outlet faces the user's ear canal. The upper half of the first earphone body includes a first surface facing the outside of the ear and not in contact with the skin. The first surface is provided with a pressure sensor, and the pressing operation includes the user pressing the first surface.

[0011] Based on the above solution, when a user wears the headphones, the first earphone body is held in the concha cavity with its clamping force directed towards the ear, thus securing the first earphone body to the ear. Furthermore, when the user presses on the first surface of the upper part of the first earphone body while wearing the headphones, the pressure is also directed towards the ear, which enhances the clamping effect and improves wearing stability.

[0012] It should be understood that the clamping force is also referred to as the holding force in this article.

[0013] In one possible implementation, the second earphone body includes a second surface that fits against the ear when the user wears the earphone and a third surface opposite to the second surface. When the user wears the earphone, the extension directions of both the second and third surfaces are facing the ground. The second and / or third surfaces are provided with pressure sensors, and the pressing operation includes the user pressing the third surface.

[0014] Based on the above design, when the user wears the headphones, the first earphone body is held in the concha, with its clamping force directed towards the inside of the ear, thus securing the first earphone body to the ear. Simultaneously, the ear contacts the second surface of the second earphone body, providing support for it. This support force is opposite to the clamping force of the first earphone body and is both horizontal. This enhances the horizontal stability of the headphones when worn, preventing them from wobbling horizontally. When the user presses the third surface, the pressure is perpendicular to it. Overall, when the user wears the headphones, the first and second earphone bodies are held in place by a connecting arm, with both clamping forces directed horizontally towards the user's ear, and the pressure applied also directed towards the ear. This enhances the clamping effect and improves wearing stability.

[0015] In one possible implementation, when the user wears the headphones, a pressure sensor is provided on the fourth side of the connecting arm opposite the skin-facing side, and the pressing operation includes the user pressing the fourth side.

[0016] Based on the above solution, when the user wears the headphones, the first and second earpieces are held on the ear by a connecting arm, and the clamping force of both earpieces is horizontally directed towards the user's ear. When the user presses the fourth side, the pressing force is also directed towards the ear, which increases the clamping effect and improves the stability of wearing the headphones.

[0017] In one possible implementation, a pressure sensor is provided on a first surface of the first earphone body and a pressure sensor is provided on a second surface of the second earphone body; or, a pressure sensor is provided on a first surface of the first earphone body and a pressure sensor is provided on a third surface; or, a pressure sensor is provided on a first surface of the first earphone body, a pressure sensor is provided on a second surface of the second earphone body, and a pressure sensor is provided on a third surface of the second earphone body, and the pressing operation includes the user pressing the first surface and the user pressing the third surface.

[0018] Based on the above solution, when the user wears the headphones, the first and second earpieces are held on the ear by a connecting arm, and the clamping force of both earpieces is horizontally directed towards the user's ear. When the user presses on both the first and third surfaces simultaneously, the pressure on both surfaces is directed towards the ear, which increases the clamping effect and improves the stability of the headphones.

[0019] In one possible implementation, the target function instruction is determined by: determining the user's target pressing gesture based on a pressure signal; and determining the target function instruction based on the target pressing gesture.

[0020] Based on the above scheme, the pressure signal is converted into gesture recognition. By taking advantage of the relatively stable nature of gestures, the user's operation intention is accurately captured, reducing the risk of misjudgment caused by factors such as pressure signal fluctuations and improving the accuracy of the determined target function command.

[0021] In one possible implementation, determining the user's target pressing gesture based on the pressure signal includes: determining the signal changes of the pressure signal; and determining the target pressing gesture based on the signal changes, wherein the signal changes include at least one of the following: changes in the magnitude of the pressure value, changes in the rate of increase and decrease of the pressure value, and the duration of the pressure.

[0022] Based on the above scheme, signal changes can be determined based on pressure signals. These changes reflect the dynamic characteristics of pressure in multiple dimensions, such as duration, during a user's pressing operation. These characteristics are used to determine the user's target pressing gesture, improving the accuracy and reliability of this determination. Furthermore, since the user's hair, sweat, and surface dirt do not interfere with the pressure signal, the accuracy of the target pressing gesture determined by the pressure signal is ensured, thereby improving the accuracy and reliability of triggering corresponding function commands based on the target pressing gesture.

[0023] In one possible implementation, determining the user's target pressing gesture based on the pressure signal includes: using a gesture detection model to process the pressure signal to determine the target pressing gesture.

[0024] The pressure signal can be input into the gesture detection model, which can process the pressure signal and finally output a pressing gesture corresponding to the pressure signal, and use it as the target pressing gesture.

[0025] Alternatively, a gesture detection model can be used to process the pressure signal, obtaining candidate pressing gestures and their confidence levels. Based on the confidence levels, the target pressing gesture is determined from the candidate gestures. The number of candidate pressing gestures can be at least one. The confidence level of a candidate pressing gesture represents its credibility (reliability). Based on the confidence level, candidate pressing gestures can be filtered to identify the target pressing gesture. This method reduces the possibility of false positives or false negatives, thereby improving the accuracy and reliability of gesture recognition and ensuring that the headphones can reliably and accurately recognize the user's pressing gestures in practical applications.

[0026] Based on the above scheme, the recognition capability of the gesture detection model can be used to process the pressure signal to identify the target pressing gesture corresponding to the pressure signal, thereby improving the efficiency and accuracy of determining the target pressing gesture.

[0027] In one possible implementation, determining the user's target pressing gesture based on the pressure signal includes: determining the waveform of the pressure signal; and if, in the case that there exists a signal waveform in the signal waveform of at least one pressing gesture that matches the waveform of the pressure signal, taking the pressing gesture corresponding to the signal waveform that matches the waveform of the pressure signal as the target pressing gesture.

[0028] Based on the above scheme, acquiring the waveform of the pressure signal does not require complex processing of the pressure signal, and the waveform retains the original information of the pressure signal. Based on this, the user's target pressing gesture is determined, improving the accuracy of the determined target pressing gesture and thus improving the accuracy of triggering corresponding interactive functions based on the target pressing gesture. Furthermore, this method simplifies the process of determining the target pressing gesture and improves its efficiency.

[0029] In one possible implementation, the target function instruction is determined based on the target pressing gesture, including: determining the target function instruction based on the target pressing gesture and the target correspondence, wherein the target correspondence is the correspondence between the pressing gesture and the function instruction.

[0030] Based on the above scheme, the target function command corresponding to the target pressing gesture can be determined based on the target correspondence, which improves the efficiency of determining the target function command so that the target function command can be executed in a timely manner, thereby improving the efficiency and timeliness of the interactive response.

[0031] In one possible implementation, the terminal device is notified to execute a target function instruction based on a pressure signal, including: if the type of the target function instruction determined based on the pressure signal is a first type, the terminal device is notified to execute the target function instruction.

[0032] The first type of target function commands includes: media control commands, call management commands, and voice assistant wake-up commands. Media control commands include play / pause / listen to music commands and volume up / down commands. Call management commands include answer / hang up commands and call switching commands.

[0033] Based on the above solution, the headphones can determine the executor of the target function instruction based on the type of the target function instruction, realizing intelligent allocation of function instructions, ensuring that the corresponding type of function instruction can be executed by the corresponding device, and improving the flexibility and intelligence of function instruction execution.

[0034] In one possible implementation, the terminal device is notified to execute a target function instruction based on a pressure signal, including: if the type of the target function instruction determined based on the pressure signal is a second type, executing the target function instruction.

[0035] The second type of target function instructions includes: noise reduction control instructions, mode switching instructions, and other function instructions.

[0036] Based on the above solution, the headphones can determine the executor of the target function instruction based on the type of the target function instruction, realizing intelligent allocation of function instructions, ensuring that the corresponding type of function instruction can be executed by the corresponding device, and improving the flexibility and intelligence of function instruction execution.

[0037] In one possible implementation, pressure sensors are provided on both the second and third surfaces of the second earpiece. The interaction method further includes: acquiring the user's current motion state; and, if the current motion state is the target motion state, controlling the pressure sensors on the second surface to be in a non-working state.

[0038] Based on the above solution, considering that when the user's current motion state is the target motion state, the second surface of the second earpiece in contact with the ear skin will experience pressure fluctuations due to inertia. In this case, the pressure sensor located on the inner side of the second surface may detect these pressure signals, potentially leading to the false triggering of corresponding function commands. Therefore, when it is determined that the user's current state is the target motion state, the pressure sensor located on the inner side of the second surface is deactivated to avoid false triggering. Simultaneously, the pressure sensor located on the inner side of the third surface of the second earpiece is kept active. This ensures that the user triggers the corresponding function commands according to actual needs, while also ensuring that the collected pressure signals are valid, thus improving the accuracy and reliability of function command triggering.

[0039] In one possible implementation, obtaining the user's current motion state includes: collecting acceleration data via the headphone's accelerometer; and determining the user's current motion state based on the acceleration data.

[0040] Based on the above scheme, motion feature information is extracted from the acceleration data collected by the headphones to determine the user's current motion state. This method captures key parameters during the user's movement to determine their current motion state, thus improving the accuracy of the determined state.

[0041] In one possible implementation, an initial pressure signal is acquired in response to a user's pressing action on a target component of the earphone; the initial pressure signal is then filtered to obtain a pressure signal.

[0042] Based on the above scheme, by filtering the initial pressure signal, noise in the initial pressure signal can be removed, ensuring the signal quality of the final pressure signal and further improving the accuracy of the target function command determined based on the pressure signal.

[0043] In a second aspect, embodiments of this application provide an earphone, which includes a processor and a memory. The memory is used to store a computer program, and the processor is used to call and run the computer program from the memory, causing the earphone to perform any of the methods in the first aspect.

[0044] Thirdly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, causes the processor to perform any of the methods in the first aspect.

[0045] Fourthly, embodiments of this application provide a computer program product, which includes computer program code that, when executed by an earphone, causes the earphone to perform any of the methods in the first aspect.

[0046] Fifthly, embodiments of this application provide a chip system including a processing circuit and a storage medium, wherein the storage medium stores computer program instructions; when the computer program instructions are executed by the processing circuit, they implement any of the methods in the first aspect.

[0047] Optionally, the processing circuitry in the above-mentioned chip system can be replaced by a processor, and the storage medium can be replaced by a memory. Optionally, the chip system may also include a communication interface for enabling communication between the chip system and external devices.

[0061] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0062] 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 document is merely a description of the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more.

[0063] Hereinafter, the terms "first," "second," and "third" 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," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0064] Currently, users' needs for headphones span multiple scenarios, including daily life, entertainment, work, and travel. However, traditional in-ear headphones need to be inserted deep into the ear canal and secured by a tight fit between the ear tip and the ear canal wall, which can put pressure on the ear canal. After prolonged wear, the ear canal may experience pain, itching, and even ear canal inflammation due to this pressure.

[0065] In this context, clip-on headphones have entered people's lives. Clip-on headphones are audio devices distinct from traditional in-ear and over-ear headphones, typically consisting of two earpieces and a connecting arm. During use, the earpieces are clipped onto the outer contour of the ear (auricle) for wearing, avoiding direct pressure on the ear canal and thus preventing discomfort caused by ear canal pressure, providing a comfortable and imperceptible wearing experience. However, due to the limitations of their structure, clip-on headphones have a smaller interactive interface, and their pursuit of an imperceptible wearing effect presents significant challenges to user interaction.

[0066] Therefore, how to implement interactive control on clip-on headphones is a problem that urgently needs to be solved.

[0067] In some possible examples, capacitive touch sensors are placed on the earpiece of clip-on headphones, located behind the user's ear. These sensors rely on changes in capacitance. The sensors detect whether a person is in contact with the headphones to trigger corresponding interactive functions. However, this approach has drawbacks. Because capacitive touch sensors are sensitive to their surroundings—factors such as hair or sweat can interfere with the sensor, leading to accidental touches and a reduced user experience.

[0068] Based on this, this application provides an interaction method applied to earphones, specifically clip-on earphones. The earphones are equipped with a pressure sensor that directly measures physical pressure to trigger corresponding interactive functions. This eliminates the need for capacitive touch sensors to detect human contact with the earphones, avoiding interference from hair, sweat, and surface dirt, reducing accidental touches, improving interaction accuracy, and further enhancing the user experience.

[0069] The earphones can be true wireless stereo (TWS) earphones, which clip onto the ear. Clip-on earphones can reduce ear discomfort and improve wearing comfort. The earphones include a first earphone body, a connecting arm, and a second earphone body, with the connecting arm connecting the first and second earphone bodies. When the user wears the earphones, the first earphone body is held inside the user's concha, and the second earphone body is located outside the ear and on the side opposite to the first earphone body.

[0070] Figure 1 This is a schematic diagram of the structure of the earphone provided in an embodiment of this application. Figure 1As shown, the earphone includes a first earphone body 101, a connecting arm 102, and a second earphone body 103. One end of the connecting arm 102 is connected to the first earphone body 101, and the other end is connected to the second earphone body 103. The first earphone body 101 and the second earphone body 103 are physically connected via the connecting arm 102. Furthermore, the first earphone body 101 and the second earphone body 103 are electrically connected via the connecting arm 102.

[0071] At least one of the three components—the first earphone body 101, the connecting arm 102, and the second earphone body 103—is equipped with a pressure sensor. When a user wears the earphone, the pressure sensor can detect the user's pressing action, obtain a pressure signal, and trigger corresponding interactive functions based on the pressure signal.

[0072] Figure 2 This is a schematic diagram of a user using headphones 100 according to an embodiment of this application. The first headphone body 101 can be used to produce sound, such as... Figure 2 As shown, when a user uses the headphones, the first headphone body 101 is held in the user's concha cavity.

[0073] It should be understood that the concha is the recessed area around the entrance to the external auditory canal, located on the inner side of the auricle, and is shaped like a sphere or ellipsoid. The first earphone body is held in place within the user's concha without penetrating deep into the ear canal. The natural concha's recess allows for a secure fit, greatly improving wearing comfort.

[0074] The second earphone body 103 is located outside the user's ear and on the side opposite to the first earphone body 101. The connecting arm 102 is fastened to the outer edge of the user's ear and extends from the concha to the back of the ear. The connecting arm 102 fastening to the outer edge of the user's ear and extending from the concha to the back of the ear can be understood as the first earphone body 101 and the second earphone body 103 together clamping the user's auricle through the connecting arm 102, thereby wearing the earphone on the ear.

[0075] In one possible implementation, the first earphone body 101 can be approximately spherical in shape, and can also be referred to as the ball end of the earphone. The second earphone body 103 can be bean-shaped, and can also be referred to as the bean end.

[0076] In one possible implementation, the user's target pressing gesture is determined based on the pressure signal, and the target function command is triggered based on the target pressing gesture.

[0077] Example 1: A pressure sensor is deployed at the end of the ball. The target pressing gesture can include any of the following: pushing the ball once, pushing the ball twice, pushing the ball three times… pushing the ball N times, or pushing the ball and holding. For example, pushing the ball once corresponds to adjusting the volume to level 1; pushing the ball twice corresponds to adjusting the volume to level 2; pushing the ball three times corresponds to adjusting the volume to level 3; pushing the ball N times corresponds to adjusting the volume to level N; and pushing the ball and holding corresponds to activating mute mode. Here, N is a positive integer greater than 3 and less than or equal to M, where M is the maximum number of volume levels that can be adjusted.

[0078] Example 2: A pressure sensor is deployed on the bean. The target pressing gesture can include any of the following: pushing the bean once, pushing the bean twice, pushing the bean three times... pushing the bean N times, or pushing the bean and holding. For example, pushing the bean once corresponds to a function command such as fast-forwarding the video for 30 seconds; pushing the bean twice corresponds to a function command such as fast-forwarding the video for 60 seconds; pushing the bean three times corresponds to a function command such as fast-forwarding the video for 3 minutes; pushing the bean N times corresponds to a function command such as fast-forwarding the video for N minutes; and pushing the bean and holding corresponds to a function such as pausing video playback. Here, N is a positive integer greater than 3 and less than or equal to K, where K is the maximum fast-forward time that the video can be adjusted in the current playback context, and its value is determined by a combination of factors such as the total duration of the video and the playback progress.

[0079] Example 3: Pressure sensors are deployed on both the ball and bean ends. Target pressing gestures can include, for example, any one of the following: squeezing the bean once, squeezing the bean twice, squeezing the bean three times, squeezing the bean N times, or squeezing and holding the bean. The function command corresponding to squeezing the bean once is, for example, answering a phone call; squeezing the bean twice corresponds to starting call recording; squeezing the bean three times corresponds to hanging up the phone; squeezing the bean N times corresponds to muting the call; and squeezing and holding the bean corresponds to activating hands-free calling. Here, N is a positive integer greater than 3.

[0080] It should be noted that the above-mentioned target pressing gestures and corresponding function commands are merely examples and do not constitute a limitation on the target pressing gestures and function commands. In practical applications, the target pressing gestures and corresponding function commands can be flexibly set, and the embodiments of this application do not specifically limit the target pressing gestures and their corresponding function commands.

[0081] It should be understood that a pressure sensor is a sensor that can sense changes in pressure and convert them into electrical signals.

[0082] In one possible implementation, the pressure sensor includes, but is not limited to: piezoresistive sensors, capacitive sensors, ionoelectric sensors, piezoelectric thin-film sensors, optical pressure sensors, etc. Among them:

[0083] Piezoresistive sensor: A piezoresistive sensor is a sensor that works based on the piezoresistive effect. It can convert pressure into a measurable electrical signal, such as a change in resistance or voltage. The piezoresistive effect refers to the deformation of the crystal structure of semiconductor materials (such as silicon and germanium) or metal materials when subjected to external force, which causes a change in the mobility of charge carriers and thus a change in resistivity.

[0084] A pressure-capacitive sensor is a pressure measuring device that operates based on the principle of capacitance change. It converts pressure into measurable electrical signals such as capacitance, voltage, or frequency by utilizing the changes in the structural parameters of a capacitor caused by the measured physical quantity (such as pressure), achieving high-precision, high-sensitivity non-contact or contact measurement. It should be understood that although both pressure-capacitive sensors and capacitive touch sensors rely on the principle of capacitance change, they are completely different. Pressure-capacitive sensors output continuous pressure values ​​by quantifying capacitance changes, reflecting both the magnitude and dynamic changes of pressure. Capacitive touch sensors, on the other hand, only detect the presence or location of a touch event and do not involve pressure quantification.

[0085] An ionization sensor is a sensor that converts changes in pressure into changes in ionization current or capacitance. It typically consists of two conductive electrodes and an ion-conducting layer (such as an ionized water film or ion gel) sandwiched in between. By migrating or redistributing ions in an elastic dielectric, it causes significant changes in conductivity or capacitance, thereby achieving high sensitivity and a wide measurement range.

[0086] Piezoelectric thin film sensor: It is a sensor based on the piezoelectric effect. Its core is a thin film made of piezoelectric material (such as polyvinylidene fluoride) that generates charge or potential difference when subjected to mechanical pressure or deformation, thereby converting mechanical energy into electrical signal output, realizing the sensing and measurement of physical quantities such as pressure, vibration, and acceleration.

[0087] Optical pressure sensor: a sensor that senses pressure or deformation by detecting changes in light signals based on optical principles.

[0088] The above are merely some examples of pressure sensors and do not constitute a limitation on pressure sensors. In practical applications, pressure sensors can also be other sensors capable of sensing pressure changes and converting them into electrical signals. This application does not specifically limit the pressure sensor used in its embodiments.

[0089] The following combination Figure 3 , Figure 9 , Figure 10as well as Figure 11 This application provides a detailed explanation of the interaction methods provided.

[0090] Figure 3 This is a flowchart illustrating an interaction method 300 provided in an embodiment of this application. The interaction method 300 is applied to... Figure 1 or Figure 2 The earphone shown includes a first earphone body 101, a connecting arm 102, and a second earphone body 103. The connecting arm 102 connects the first earphone body 101 and the second earphone body 103. When a user wears the earphone, the first earphone body 101 is held within the user's concha, and the second earphone body 103 is located outside the user's ear and on the side opposite to the first earphone body 101. Figure 3 As shown, the interaction method 300 includes S301 to S303. This interaction method 300 does not rely on... Figure 3 The specific order is a limitation. It should be understood that in other embodiments, the order of some steps in this interaction method 300 can be interchanged according to actual needs, or some steps can be omitted or deleted. The following provides a detailed explanation of each step.

[0091] S301: In response to a user's press operation on a target component of the headphones, acquire a pressure signal.

[0092] The target component includes at least one of the first earphone body 101, the connecting arm 102, and the second earphone body 103.

[0093] In this embodiment, when a user presses a target component of the earphone, a pressure sensor on the target component detects this pressure change, measures the physical pressure value, and converts it into a pressure signal. The pressure signal reflects information such as pressure magnitude and trend. The pressure signal can be a voltage signal, a current signal, or other forms of signal.

[0094] It should be understood that the pressure sensor is positioned at a location that accurately reflects the measured pressure, ensuring that the actual force direction of the pressure sensor aligns with its design direction. This improves the accuracy and reliability of pressure detection, avoids measurement errors caused by improper positioning or force direction deviations, and ensures that the acquired pressure signal truly and accurately reflects the pressure condition experienced by the target component, thereby enhancing the accuracy of determining target functional commands based on the pressure signal.

[0095] Meanwhile, in order to ensure the stability of the headphones when worn by users and to avoid problems such as loosening or shifting of the headphones due to pressing operations, the specific placement of the pressure sensor on the target component and the user's pressing operation position have been comprehensively considered.

[0096] The following is a detailed explanation of the location of the pressure sensor and the pressing operation.

[0097] In one possible implementation, the first end of the connecting arm 102 is connected to the upper half of the first earphone body 101, and the sound outlet is located in the lower half of the first earphone body 101. When the user wears the earphone, the sound outlet faces the user's ear canal. The upper half of the first earphone body 101 includes a first surface facing the outside of the ear and not in contact with the skin. A pressure sensor is provided on the first surface, and the pressing operation includes the user pressing the first surface.

[0098] For example, Figure 4A This is a schematic diagram of another type of headphone 100 provided in an embodiment of this application. (See attached diagram.) Figure 4A As shown, the first end of the connecting arm 102 is connected to the upper half of the first earphone body 101, the sound outlet is located in the lower half of the first earphone body 101, and the second end of the connecting arm 102 is connected to the second earphone body 103. Figure 5 This is a schematic diagram of another user using the headphones 100 provided in an embodiment of this application. Figure 5 The image shows a first surface of a first earphone body 101, on the inner side of which a pressure sensor is disposed. (See image for details.) Figure 5 As shown, the pressing operation can be a user pressing the first surface. In some embodiments, the first earphone body 101 is approximately spherical, including an upper half and a lower half, wherein the upper half and the lower half are symmetrically arranged, and both the upper half and the lower half are hemispheres. In some embodiments, the interface between the upper half and the lower half is a surface perpendicular to the extension line of the connecting arm 102 on the first earphone body 101, and this surface is the surface with the largest diameter, such as... Figure 4A As shown.

[0099] Based on the above solution, when a user wears the headphones, the first earphone body 101 is held in the concha cavity with its clamping force directed towards the ear, thus securing the first earphone body 101 to the ear. Furthermore, when the user presses on the first surface of the upper part of the first earphone body 101 while wearing the headphones, the pressure is also directed towards the ear, which enhances the clamping effect and improves wearing stability. This clamping force is also referred to as the holding force.

[0100] Furthermore, a pressure sensor is installed on the inner side of the first surface. When the user presses on the first surface, the pressure sensor can directly detect the pressure change. Because there is no internal structural obstruction between the pressure sensor and the pressing surface, the signal transmission path is simple and direct, avoiding signal attenuation and distortion caused by complex signal transmission paths due to internal structural obstruction. This improves the accuracy of determining the target function command based on the acquired pressure signal. Moreover, since the pressure sensor detects changes in force, it is not affected by the user's hair, sweat, or surface dirt, preventing accidental touches and further improving the accuracy of determining the target function command based on the collected pressure signal.

[0101] In one example, the first earphone body 101 is approximately spherical in shape. When a user wears the earphone, the natural concavity of the ear canal secures the first earphone body 101. When the user wears the earphone, the first surface is the upper half of the first earphone body 101 exposed to the outside world for the user to touch. When the user wears the earphone, the first earphone body 101 is held in place within the ear canal. The area of ​​the upper half of the first earphone body 101 available for user operation is relatively small, facilitating single-finger operation. When the user operates the first surface of the upper half of the first earphone body 101 with a single finger, the unique shape of the ear canal (such as concavity or convexity) provides multi-point support and clamping for the first earphone body 101, improving its stability. For example, the lower half of the first earphone body 101 is enclosed by the ear canal wall, restricting its movement towards the ear canal, while the clamping force resists horizontal sliding of the first earphone body 101. When wearing the headphones, when the user presses the first surface on the upper half of the first earphone body 101, the pressing force, clamping force, the weight of the first earphone body 101, and the frictional force generated by the contact surface between the first earphone body 101 and the ear will cancel each other out to form a force balance, ensuring the stability of the headphones and improving the user experience.

[0102] In one possible implementation, the second earphone body 103 includes a second surface that fits against the ear when the user wears the earphone and a third surface opposite to the second surface. When the user wears the earphone, the extension directions of the second and third surfaces are both facing the ground. The second and / or third surfaces are provided with pressure sensors, and the pressing operation includes the user pressing the third surface. Figure 6 This is a schematic diagram of another user using headphones 100 provided in an embodiment of this application. Figure 6 The image shows a second surface of the second earphone body 103 and a third surface opposite to the second surface. A pressure sensor is disposed on the inner side of at least one of the second and third surfaces. (See image for details.) Figure 6 As shown, the pressing operation allows the user to press on the third side of the second earphone body 103.

[0103] Based on the above solution, when the user wears the headphones, the first earphone body 101 is held in the concha cavity, with its clamping force directed towards the inside of the ear, thus fixing the first earphone body 101 to the ear. Simultaneously, the ear contacts the second surface of the second earphone body 103, providing support for the second earphone body 103. This support force is opposite to the clamping force of the first earphone body 101 and is both horizontal. This enhances the horizontal stability of the headphones when worn, preventing them from wobbling horizontally. When the user presses the third surface, the pressing force is perpendicular to the third surface. Overall, when the user wears the headphones, the first earphone body 101 and the second earphone body 103 are held on the ear by the connecting arm 102, and the clamping forces of both are horizontally directed towards the user's ear, as is the pressing force. This enhances the clamping effect and improves wearing stability.

[0104] Furthermore, when a user presses on the third surface, pressure sensors located on the inner sides of the second and / or third surfaces can directly detect the pressure change. This is because there is no internal structural obstruction between the pressure sensor and the surface subjected to force, resulting in a simple and direct signal transmission path. This avoids signal attenuation and distortion caused by complex signal transmission paths due to internal structural obstruction, thus improving the accuracy of determining the target function command based on the acquired pressure signal. Moreover, since the pressure sensor detects changes in force, it is not affected by the user's hair, sweat, or surface dirt, preventing accidental touches and further improving the accuracy of determining the target function command based on the collected pressure signal.

[0105] In one example, such as Figures 4A-4B As shown, the first earphone body 101 is approximately spherical, with the first end of the connecting arm 102 connected to the upper half of the sphere, the sound outlet located in the lower half of the sphere, and the second end of the connecting arm 102 connected to the second earphone body 103. Wherein, as... Figure 4BAs shown, the centers of the outer surfaces of the first earphone body 101, the second earphone body 103, and the connecting arm 102 form a symmetry plane OO. When a user wears the earphones, the sound outlet faces the user's ear canal, and part of the user's ear passes through the symmetry plane. The second earphone body 103 includes a second surface that fits against the ear when worn by the user and a third surface opposite to the second surface. When the user wears the earphones, the extension directions of both the second and third surfaces face the ground. Pressure sensors are provided on the second and / or third surfaces, and the pressing operation includes the user pressing the third surface. The geometric centers of the outer surfaces of the first earphone body 101, the second earphone body 103, and the connecting arm 102 together determine a unique plane, which is the symmetry plane. When the user wears the earphones, this symmetry plane is perpendicular to the ear. In some embodiments, the second surface is perpendicular to the symmetry plane. In some embodiments, the third surface is perpendicular to the symmetry plane. Since the clamping force generated by the connecting arm 102 is approximately located on the plane of symmetry, and the second and / or third surfaces of the user-operated pressure sensor are perpendicular to the plane of symmetry, the direction of the pressure applied by the user when operating the pressure sensor is approximately in the same plane as the clamping force. This increases the clamping force of the headphones and does not affect the stability of the headphones worn by the user. It should be understood that the perpendicularity and parallelism described in this application may include a certain degree of error, for example, the error may be within 10 degrees or within 20 degrees.

[0106] The second earphone body 103 is shaped like a broad bean. When the user wears the earphone, the second earphone body 103 is located behind the ear. The second surface of the second earphone body 103 can conform to the user's skin behind the ear (such as the auricle skin), while the third surface opposite the second surface is exposed to the outside and can be operated by the user. A pressure sensor is set on the inner side of the second surface. Because the second surface conforms to the user's ear (such as the auricle skin), when the user presses the third surface, the pressure between the second surface and the auricle skin changes. The pressure sensor on the inner side of the second surface can detect this change, collect the pressure signal, and then determine the user's target function command based on the pressure signal. A pressure sensor is also set on the inner side of the third surface. The third surface is parallel to the second surface and exposed to the outside and can be touched by the user. When the user presses the third surface, the pressure sensor on the inner side of the third surface can detect this change, collect the pressure signal, and then determine the user's target function command based on the pressure signal.

[0107] Based on the above example, when a user wears the headphones, the first earphone body 101 is held in the concha cavity, with its clamping force directed towards the inside of the ear, thus fixing the first earphone body 101 in place. The second earphone body 103 is located behind the ear, and the skin behind the ear provides support for the second earphone body 103. Its force (supporting force) is opposite to the clamping force of the first earphone body 101, and both are horizontal. This enhances the horizontal stability of the headphones when worn, preventing them from wobbling horizontally. Furthermore, the centers of the outer surfaces of the first earphone body 101, the second earphone body 103, and the connecting wall form a plane of symmetry. When the user wears the headphones, part of the user's ear passes through this plane of symmetry. This structural design results in a symmetrical overall distribution of the headphones. Consequently, the force on the headphones is more evenly distributed during wear, further improving the stability of the headphones when worn by the user. When the user presses the third side, the direction of the pressure is perpendicular to the ear and perpendicular to the second side. This pressure and the supporting force of the ear on the second earphone body 103 are both horizontal relative forces. Furthermore, under the pressure, the second earphone body 103 fits more snugly against the skin behind the ear, increasing the friction between the skin and the second earphone body 103. This friction helps to balance the weight of the second earphone body 103. In this situation, the pressing pressure, clamping force, supporting force, the weight of the second earphone body 103, and the friction generated between the second earphone body 103 and the contact surface with the ear cancel each other out, forming a force balance that ensures the stability of the earphone wearing and improves the user experience.

[0108] In one possible implementation, when the user wears the headphones, a pressure sensor is provided on the fourth side of the connecting arm 102 opposite the skin side, and the pressing operation includes the user pressing the fourth side. Figure 7 This is a schematic diagram illustrating another user's use of headphones 100, provided as another embodiment of this application. (See diagram below.) Figure 7 As shown, a fourth surface of the connecting arm 102, facing the skin, is illustrated, and a pressure sensor is disposed on the inner side of this fourth surface. Figure 7 As shown, the pressing operation is the operation in which the user presses the fourth side of the connecting arm 102.

[0109] Based on the above solution, when the user wears the headphones, the first earphone body 101 and the second earphone body 103 are clamped on the ear by the connecting arm 102, and the clamping force of the first earphone body 101 and the second earphone body 103 is both directed horizontally towards the user's ear. When the user presses the fourth side, the pressing force is also directed towards the ear, which can increase the clamping effect and improve the stability of wearing the headphones.

[0110] Furthermore, when a user presses on the fourth surface of the connecting arm 102, the pressure sensor located inside the fourth surface can directly detect the pressure change. This is because there is no internal structural obstruction between the pressure sensor and the force-bearing surface, making the signal transmission path simple and direct. This avoids signal attenuation and distortion caused by complex signal transmission paths due to internal structural obstruction, and improves the accuracy of determining the target function command based on the obtained pressure signal.

[0111] In one example, such as Figure 4A As shown, the first earphone body 101 is spherical. The first end of the connecting arm 102 is connected to the upper half of the sphere, and the sound outlet is located in the lower half of the sphere. The second end of the connecting arm 102 is connected to the second earphone body 103. The center of the outer surface of the first earphone body 101, the center of the outer surface of the second earphone body 103, and the center of the outer surface of the connecting arm 102 form a plane of symmetry. When the user wears the earphone, the sound outlet faces the user's ear canal, and the part of the user's ear passes through the plane of symmetry. A pressure sensor is provided on the fourth surface of the connecting arm 102 opposite to the skin-facing side. The pressing operation includes the user pressing the fourth surface. When the user wears the earphone, the skin-facing side of the connecting arm 102 may be in contact with the skin; of course, the skin-facing side of the connecting arm 102 may not be in contact with the skin, i.e., there is a certain gap between them. The fourth surface opposite to the skin-facing side of the connecting arm 102 is exposed to the outside and can be operated by the user.

[0112] Based on the above example, when a user wears the headphones, the first earphone body 101 is held in the concha cavity, with its clamping force directed towards the inside of the ear, thus fixing the first earphone body 101 in place. The second earphone body 103 is located behind the ear, and the skin behind the ear provides support for the second earphone body 103. Its force (supporting force) is opposite to the clamping force of the first earphone body 101, and both are horizontal. This enhances the horizontal stability of the headphones when worn, preventing them from wobbling horizontally. Furthermore, the centers of the outer surfaces of the first earphone body 101, the second earphone body 103, and the connecting wall form a plane of symmetry. When the user wears the headphones, part of the user's ear passes through this plane of symmetry. This structural design results in a symmetrical overall distribution of the headphones. This ensures more even force distribution during wear, further improving the stability of the headphones when worn. When the user presses the fourth side of the connecting arm 102 away from the ear while wearing the headphones, the pressure is transmitted through the connecting arm 102 to the first earphone body 101 and the second earphone body 103. The first earphone body 101 is held in the concha cavity. For the first earphone body 101, the component of the pressing force directed towards the ear canal is balanced by the frictional force generated by the contact between the first earphone body 101 and the ear skin, and by the supporting force provided by the lower half of the first earphone body 101 being wrapped by the concha cavity wall. For the second earphone body 103, the component of the pressing force is balanced by the frictional force between the second earphone body 103 and the skin behind the ear, ensuring the stability of the second earphone body 103 on the ear.

[0113] In one possible implementation, a pressure sensor is provided on a first surface of the first earphone body 101 and a pressure sensor is provided on a second surface of the second earphone body 103; or, a pressure sensor is provided on a first surface of the first earphone body 101 and a pressure sensor is provided on a third surface; or, a pressure sensor is provided on a first surface of the first earphone body 101, a pressure sensor is provided on a second surface of the second earphone body 103, and a pressure sensor is provided on a third surface of the second earphone body 103, and the pressing operation includes the user pressing the first surface and the user pressing the third surface. Figure 8 This is a schematic diagram of another user using headphones 100, provided for another embodiment of this application. Figure 8 This illustrates an operation where a user simultaneously presses on the first surface of the first earphone body 101 and the third surface of the second earphone body 103. This operation can also be described as a pinching operation.

[0114] Based on the above solution, when the user wears the headphones, the first earphone body 101 and the second earphone body 103 are clamped on the ear via the connecting arm 102, and the clamping force of the first earphone body 101 and the second earphone body 103 is both directed horizontally towards the user's ear. When the user presses the first and third surfaces simultaneously, the pressing force of both surfaces is directed towards the ear, which increases the clamping effect and improves the stability of wearing the headphones.

[0115] Furthermore, pressure sensors are installed on both the first earphone body 101 and the second earphone body 103. These pressure sensors can detect the pressure changes on the corresponding surfaces when the user simultaneously presses the first surface of the first earphone body 101 and the third surface of the second earphone body 103, and collect the pressure signals. The user's target function command can then be determined based on these pressure signals to trigger the corresponding interactive function. Because the pressure sensors detect changes in force, they are not affected by the user's hair, sweat, or surface dirt, reducing the false touch rate and improving the accuracy of the target function command determined based on the collected pressure signals, thereby improving the accuracy of the interaction.

[0116] In one example, when a user wears the headphones, the first earphone body 101 is held in the concha cavity with its clamping force directed towards the inner ear, thus securing the first earphone body 101 to the ear. The second earphone body 103 is located behind the ear, and the skin behind the ear provides support for the second earphone body 103. Its force (supporting force) is opposite to the clamping force of the first earphone body 101, and both are horizontal. This enhances the horizontal stability of the headphones during wear, preventing them from wobbling horizontally. Furthermore, the centers of the outer surfaces of the first earphone body 101, the second earphone body 103, and the connecting wall form a plane of symmetry. When the user wears the headphones, part of the ear passes through this plane of symmetry. This structural design results in a symmetrical overall distribution of the headphones. This ensures more even force distribution during wear, further improving the stability of the headphones. On the other hand, from an overall perspective, both the user's pressing actions on the first and third surfaces are directed towards the ear. When a user wears headphones, their ears provide support and holding force to the headphones as a whole. This support and holding force interacts with the pressure applied at these two points to achieve a balance, further ensuring the stability of the headphones when worn.

[0117] In this embodiment, when pressure sensors are provided on both the second surface of the second earphone body 103 that conforms to the skin of the ear and the third surface opposite to the second surface, the state of the pressure sensor provided on the inner side of the second surface can be controlled based on the user's current movement state. The user's current movement state can be detected by the earphone or detected by other devices (such as a terminal device) and then sent to the terminal device.

[0118] For example, a user's movement states include a stationary state, a walking state, and a running state. In a stationary state, the user's body does not exhibit significant displacement or movement, such as sitting, lying down, or standing still. In a walking state, the user primarily moves by walking, at a relatively slow speed and with a regular rhythm. In a running state, the user primarily moves by running, at a relatively fast speed and with a larger range of motion.

[0119] In one possible implementation, the user's current motion state is obtained by: collecting acceleration data through the accelerometer of the headphones; and determining the user's current motion state based on the acceleration data.

[0120] For example, an accelerometer, such as a triaxial accelerometer, can measure the acceleration data of an object. In three-dimensional space, each acceleration data point can be represented as (Ax, Ay, Az), which describes the acceleration state of the object in three-dimensional space. When a user wears headphones, the accelerometer in the headphones can collect acceleration data in three-dimensional space. By analyzing this acceleration data, motion characteristic information is determined, and the user's current motion state is determined based on this motion characteristic information. The motion characteristic information includes time-domain features, frequency-domain features, and time-series features. Time-domain features are calculated directly from the original time series of acceleration data and can reflect the instantaneous or overall characteristics of the motion. Frequency-domain features convert the time-domain signal to the frequency domain using Fourier transform to analyze the periodicity or frequency components of the motion. Time-series features focus on the time series of acceleration data to capture the periodicity or regularity of the motion.

[0121] The following provides an illustrative explanation of these motion characteristic information.

[0122] Time-domain characteristics include: mean, variance / standard deviation, and peak acceleration per unit time. The mean, or average acceleration value per unit time, reflects the overall motion intensity. For example, when a user is stationary, the mean is close to the gravitational acceleration g≈9.8 m / s². 2 However, the average value during running may be slightly higher than g≈9.8m / s due to the up-and-down swing of the body. 2When a user runs, the mean may be slightly higher than g due to the up-and-down swaying of the body. Variance / Standard Deviation: These two metrics measure the dispersion of the acceleration signal, thus reflecting the variability of the motion. During walking, the variance is typically between 0.1 and 1.0 m. 2 / s 4 However, when running, due to the larger range of motion, the variance may exceed 1.0m. 2 / s 4 The peak acceleration per unit time occurs more frequently and at a higher amplitude (e.g., exceeding 12 m / s²) during running. 2 The peak value during walking is relatively low.

[0123] Frequency domain characteristics include: dominant frequency, frequency band energy proportion, and power spectral density. Dominant frequency: the frequency with the highest energy in the spectrum, which helps distinguish different types of exercise. For example, the dominant frequency for walking is typically 1 to 3 Hz, while for running it is 3 to 5 Hz. Frequency band energy proportion: by calculating the proportion of energy in a specific frequency band (e.g., 0.5 to 10 Hz) to the total energy, it can help determine the user's current exercise state. Power spectral density: reflects the power distribution of the signal across different frequencies. During running, the power in higher frequency bands (e.g., 4 to 6 Hz) is significantly higher than that during walking.

[0124] Temporal features include step count detection and gait cycle. Step count per unit time can be calculated using peak detection or autocorrelation analysis. For example, the cadence during walking is approximately 1 to 2 steps per second, while the cadence during running is 2 to 4 steps per second. Gait cycle, the time required to complete one step, can be calculated from the time intervals of consecutive peaks. The gait cycle during running is typically shorter than that during walking.

[0125] Based on the above scheme, motion feature information is extracted from the acceleration data collected by the headphones to determine the user's current motion state. This method captures key parameters during the user's movement to determine their current motion state, thus improving the accuracy of the determined state.

[0126] In one possible implementation, the state of the pressure sensor located on the inner side of the second surface of the second earphone body 103 is controlled based on the user's current motion state. This is achieved by: controlling the pressure sensor located on the inner side of the second surface of the second earphone body 103 to be in a non-operating state and controlling the pressure sensor located on the inner side of the third surface to be in an operating state when the current motion state is the target motion state. Alternatively, the pressure sensor located on the inner side of the third surface is continuously in an operating state, and the pressure sensor located on the inner side of the second surface of the second earphone body 103 is controlled to be in a non-operating state when the current motion state is the target motion state.

[0127] For example, if the target motion state is running, and the user's current motion state is running, the earphone can deactivate the pressure sensor located on the inner side of the second earphone body 103. At this time, only the pressure sensor located on the inner side of the third earphone body 103 can detect the user's pressure on the third earphone. This is because during running, the second earphone body 103 in contact with the skin will experience pressure fluctuations due to inertia. In this case, the pressure sensor located on the inner side of the second earphone body 103 might detect these pressure signals, potentially triggering the corresponding function command erroneously. Therefore, when it is determined that the user's current state is running, the earphone can deactivate the pressure sensor located on the inner side of the second earphone body 103 to avoid erroneous triggering. Simultaneously, the pressure sensor located on the inner side of the third earphone body 103 remains active, ensuring that the user triggers the corresponding function command according to actual needs, and also ensuring that the collected pressure signal is a valid signal, thus improving the accuracy and reliability of function command triggering.

[0128] It should be noted that the target motion state mentioned above is the running state. This is just an example and does not constitute a specific limitation on the target motion state. In practical applications, the target motion state can also be the running state or other motion states. This application embodiment does not specifically limit the target motion state.

[0129] Based on the above solution, when the user's current motion state is the target motion state, the risk of accidentally triggering the corresponding function command can be avoided. At the same time, it can ensure that the corresponding function command is triggered based on the user's actual needs, thereby improving the accuracy and reliability of function command triggering.

[0130] In one possible implementation, in response to a user's pressing operation on a target component of the headphones, acquiring a pressure signal includes: acquiring an initial pressure signal in response to the user's pressing operation on the target component of the headphones; and filtering the initial pressure signal to obtain a pressure signal.

[0131] For example, when a user presses a target component of the earphone, a pressure sensor on the target component can collect a signal in response to the user's press operation to obtain an initial pressure signal. Then, the initial pressure signal is filtered to remove noise, thus obtaining the final pressure signal.

[0132] The filtering algorithms used include, but are not limited to, at least one of the following: low-pass filtering, high-pass filtering, and band-pass filtering. By filtering the initial pressure signal, noise in the initial pressure signal can be removed, ensuring the signal quality of the final pressure signal.

[0133] Optionally, after acquiring the initial pressure signal, the initial pressure signal is sequentially amplified and filtered to obtain the final pressure signal. By amplifying the initial pressure signal to increase the signal amplitude to a level comparable to or higher than the noise, it is easier to separate the signal from the noise in subsequent filtering processes, thus improving the denoising effect and further enhancing the signal quality of the final pressure signal.

[0134] S302. Based on the pressure signal, notify the terminal device to execute the target function instruction; or, execute the target function instruction based on the pressure signal.

[0135] Different pressure signals correspond to different target function commands.

[0136] In this embodiment, the headphones can determine the target function command corresponding to the pressure signal, with different pressure signals corresponding to different target function commands. These different target function commands can all be executed by the terminal device. Alternatively, all of these different target function commands can be executed by the headphones. Or, some of these different target function commands can be executed by the terminal device, while others can be executed by the headphones.

[0137] The determination of target function commands based on pressure signals can be achieved in the following ways:

[0138] In one possible implementation, the pressure signal can be matched with at least one preset pressure signal in the headphones. If there is a preset pressure signal that matches the pressure signal among the at least one preset pressure signal, the function instruction corresponding to the preset pressure signal that matches the pressure signal is taken as the target function instruction.

[0139] Based on the above scheme, no additional processing of the pressure signal is required. The target function command can be determined by matching the pressure signal with at least one preset pressure signal. This simplifies the process of determining the target function command and improves its efficiency.

[0140] In one possible implementation, the waveform of the pressure signal can be determined, and if there is a signal waveform in the signal waveform of at least one pressing gesture that matches the waveform of the pressure signal, the function instruction corresponding to the signal waveform that matches the waveform of the pressure signal is taken as the target function instruction.

[0141] Based on the above scheme, acquiring the pressure signal waveform does not require complex processing of the pressure signal, and the waveform retains the original information of the pressure signal. Based on this, the accuracy of the determined target function command is improved. Furthermore, the process of determining the target function command is simplified, thus increasing its efficiency.

[0142] In one possible implementation, the user's target pressing gesture is determined based on the pressure signal; and the target function instruction is determined based on the target pressing gesture.

[0143] Different pressure signals correspond to different target pressing gestures. Different target pressing gestures correspond to different target function commands.

[0144] Based on the above scheme, the pressure signal is converted into gesture recognition. By taking advantage of the relatively stable nature of gestures, the user's operation intention is accurately captured, reducing the risk of misjudgment caused by factors such as pressure signal fluctuations and improving the accuracy of the determined target function command.

[0145] The following is a detailed explanation of how to determine the user's target pressing gesture based on pressure signals.

[0146] In one possible implementation, the user's target pressing gesture can be determined based on at least one of the signal changes of the pressure signal and the waveform of the pressure signal.

[0147] The user's target pressing gesture can be determined based on at least one of the following methods: (The method described above is not directly related to the definition of the pressure signal and can be omitted.)

[0148] Method 1: Determine the signal changes of the pressure signal; based on the signal changes, determine the target pressing gesture.

[0149] In this embodiment, the signal change of the pressure signal can be obtained by the headphones analyzing the pressure signal. Alternatively, the headphones can send the pressure signal to a terminal device, which then analyzes the pressure signal and sends the result back to the headphones. The signal change refers to the characteristic of the pressure signal changing over time.

[0150] In one possible implementation, the signal changes include changes in the magnitude of the pressure value, changes in the rate at which the pressure value increases or decreases, and the duration of the pressure.

[0151] In one possible implementation, the earphone stores the signal changes of at least one pressing gesture. The signal changes of the pressure signal can be matched with the signal changes of at least one pressing gesture, and the pressing gesture corresponding to the signal change that matches the signal changes of the pressure signal is determined as the target pressing gesture.

[0152] For example, when matching the signal changes of a pressure signal with the signal changes of at least one pressing gesture, the matching degree of each signal change in the pressure signal can be calculated to obtain at least one first matching degree. The largest first matching degree is then determined from the at least one first matching degree. Subsequently, the largest first matching degree is compared with a first matching degree threshold. If the largest first matching degree is greater than or equal to the first matching degree threshold, the pressing gesture corresponding to the signal change of the largest first matching degree is taken as the target pressing gesture.

[0153] Based on the above scheme, signal changes can be determined from the pressure signal. These changes reflect the dynamic characteristics of pressure in terms of amplitude, frequency, and duration during the user's pressing operation. Based on these characteristics, the user's target pressing gesture can be determined, improving the accuracy and reliability of the target pressing gesture determination. Furthermore, since the user's hair, sweat, and surface dirt do not interfere with the pressure signal, the accuracy of the target pressing gesture determined based on the pressure signal is ensured, thereby improving the accuracy and reliability of triggering corresponding function commands based on the target pressing gesture.

[0154] Method 2: Determine the waveform of the pressure signal; if there is a waveform that matches the pressure signal in at least one pressing gesture signal waveform, the pressing gesture corresponding to the waveform that matches the pressure signal waveform is taken as the target pressing gesture.

[0155] In this embodiment of the application, a waveform of a pressure signal can be generated based on the pressure signal, and the waveform of the pressure signal can be matched with the signal waveform of at least one pressing gesture. The pressing gesture corresponding to the signal waveform that matches the waveform of the pressure signal can be determined as the target pressing gesture.

[0156] For example, when matching the waveform of a pressure signal with the signal waveform of at least one pressing gesture, the matching degree of the pressure signal waveform with each signal waveform of the at least one pressing gesture can be calculated to obtain at least one second matching degree. The largest second matching degree is then determined from the at least one second matching degree. Subsequently, the largest second matching degree is compared with a second matching degree threshold. If the largest second matching degree is greater than or equal to the second matching degree threshold, the pressing gesture corresponding to the signal waveform with the largest second matching degree is taken as the target pressing gesture.

[0157] Based on the above scheme, acquiring the waveform of the pressure signal does not require complex processing of the pressure signal, and the waveform of the pressure signal retains the original information of the pressure signal. Based on this, the user's target pressing gesture is determined, improving the accuracy of the determined target pressing gesture. In addition, the process of determining the target pressing gesture is simplified, improving the efficiency of determining the target pressing gesture.

[0158] In this embodiment of the application, a gesture detection model can also be used to process the pressure signal in order to determine the target pressing gesture.

[0159] It should be understood that the gesture detection model can be obtained by training an initial gesture detection model using a neural network algorithm based on sample pressure signals and the corresponding sample pressing gestures. The network structure of the initial gesture detection model can, for example, include any network structure such as a convolutional neural network or a recurrent neural network.

[0160] In one possible implementation, the pressure signal can be input into a gesture detection model, which can process the pressure signal and finally output a pressing gesture corresponding to the pressure signal, and use it as the target pressing gesture.

[0161] In another possible implementation, a gesture detection model is used to process the pressure signal to obtain candidate pressing gestures and their confidence levels; based on the confidence levels, the target pressing gesture is determined from the candidate pressing gestures.

[0162] The number of candidate compression gestures can be at least one. The confidence level of a candidate compression gesture indicates the degree of credibility (i.e., reliability) of the candidate compression gesture.

[0163] Example 1: The number of candidate pressure gestures can be one. The candidate pressure gesture is the most likely pressure gesture determined by the gesture detection model based on the pressure signal. If the confidence of the candidate pressure gesture is greater than or equal to the target confidence threshold, the candidate pressure gesture is determined as the target pressure gesture.

[0164] Example 2: There are multiple candidate pressure gestures, each corresponding to a confidence level. Candidate pressure gestures can be those set internally by the gesture detection model. The confidence level of a candidate pressure gesture indicates the degree of confidence that the pressure signal corresponds to that candidate pressure gesture. A maximum confidence level can be determined from multiple confidence levels. If the maximum confidence level is greater than a target confidence threshold, the candidate pressure gesture corresponding to the maximum confidence level is selected as the target pressure gesture.

[0165] Based on the above scheme, candidate pressing gestures can be filtered according to confidence level to identify the target pressing gesture. This reduces the possibility of false positives or false negatives, thereby improving the accuracy and reliability of gesture recognition and ensuring that the headphones can reliably and accurately recognize the user's pressing gestures in practical applications.

[0166] In one possible implementation, a pressing gesture determined based on at least one of the signal changes and waveforms of the pressure signal can be used as a first candidate pressing gesture; at least one candidate pressing gesture output by the gesture detection model can be used as a second candidate pressing gesture. A maximum confidence level is determined from the confidence levels of the at least one second candidate pressing gesture. If the maximum confidence level is greater than a target confidence level threshold, the second candidate pressing gesture corresponding to the maximum confidence level is matched with the first candidate pressing gesture to obtain a matching result. If the matching result indicates that the second candidate pressing gesture corresponding to the maximum confidence level matches the first candidate pressing gesture, the first candidate pressing gesture is used as the target pressing gesture. Here, the matching of the second candidate pressing gesture corresponding to the maximum confidence level with the first candidate pressing gesture can be understood as the second candidate pressing gesture corresponding to the maximum confidence level being identical to the first candidate pressing gesture.

[0167] Based on the above scheme, the target pressing gesture is determined by combining at least one defined pressing gesture from the pressure signal's waveform and its changes with the pressing gesture output by the gesture detection model. This approach utilizes both the characteristics of the pressure signal and the recognition capabilities of the gesture detection model to identify the target pressing gesture, reducing the risk of misjudgment and improving the accuracy and reliability of the determined target pressing gesture.

[0168] In this embodiment, a target function instruction corresponding to the target press gesture can be obtained. The type of target function instruction is not distinguished; all types of target function instructions can be executed by the terminal device. Alternatively, all types of target function instructions can be executed by the earphone itself. The target function instruction can be determined by the earphone based on the target press gesture. Alternatively, the target function instruction can be sent by the earphone to another device, which then determines the target press gesture and sends it back to the earphone.

[0169] In one possible implementation, obtaining the target function instruction corresponding to the target press gesture includes: determining the target function instruction based on the target press gesture and the target correspondence, wherein the target correspondence is the correspondence between the press gesture and the function instruction; the target correspondence is preset and stored in the earphone.

[0170] It should be understood that the target mapping relationship is a one-to-one correspondence between press gestures and function commands. The target mapping relationship can be presented in other data structure forms such as tables and tree structures.

[0171] For example, the target correspondence can be represented by a table. When the target pressing gesture is determined, the function instruction corresponding to the target pressing gesture can be determined by looking up the table, and the target function instruction can be obtained.

[0172] In one possible implementation, the type of target function instruction can be considered, and different types of target function instructions can be assigned to different devices for execution.

[0173] Specifically, if the target function instruction is of type 1, a notification message is sent to the terminal device. Accordingly, the terminal device executes the type 1 target function instruction based on the notification message.

[0174] For example, the first type of target function instructions includes: media control instructions, call management instructions, voice assistant wake-up instructions, etc. Among them, media control instructions include play / pause / listen to music instructions and volume up / down instructions. Call management instructions include answer / hang up instructions and call switching instructions.

[0175] When the target function instruction is of type 2, the headset executes the target function instruction (i.e., the headset does not send notification information to the terminal device).

[0176] For example, the second type of target function instructions includes noise cancellation control instructions, mode switching instructions, and other function instructions. Among them, the noise cancellation control instruction is the core operation instruction in the headphones used to manage the active noise cancellation (ANC) function. Executing this instruction can reduce or eliminate ambient noise, improving the user's listening experience. Mode switching includes switching to music mode (sound quality optimization) and game mode (low latency optimization). In music mode, the headphones can automatically adjust the frequency response curve and equalizer settings through the built-in digital signal processor (DSP) chip or audio algorithms to enhance bass or treble, thereby improving the sound quality experience. In game mode, the headphones optimize the audio transmission protocol (such as using low-latency Bluetooth encoding) to reduce the synchronization delay between sound and screen, ensuring real-time feedback of game sound effects.

[0177] Based on the above solution, the headphones can determine the executor of a target function instruction based on its type, achieving intelligent function instruction allocation. This ensures that different types of function instructions can be executed by the corresponding devices, improving the flexibility and intelligence of function instruction execution. Furthermore, when allocating execution devices for different types of function instructions, the performance, processing power, and resources of the execution devices are fully considered, achieving compatibility between different types of function instructions and execution devices. This improves the efficiency of function instruction execution and resource utilization, providing users with an efficient and seamless interactive experience.

[0178] It should be noted that the specific first-type and second-type target function instructions shown above are merely examples and do not constitute a specific limitation on the first-type and second-type target function instructions. In practical applications, the first-type and second-type target function instructions can be flexibly set according to the actual application. This application embodiment does not specifically limit the first-type and second-type target function instructions.

[0179] This application provides an interaction method applied to headphones. The headphones include a first earphone body, a connecting arm, and a second earphone body. The connecting arm connects the first and second earphone bodies. When a user wears the headphones, the first earphone body is held within the user's concha, and the second earphone body is located outside the user's ear and on the side opposite to the first earphone body. The method includes: responding to a user's pressing operation on a target component of the headphones, acquiring a pressure signal, the target component including at least one of the first earphone body, the connecting arm, and the second earphone body; based on the pressure signal, notifying a terminal device to execute a target function command; or, executing the target function command based on the pressure signal. This allows for direct measurement of physical pressure values ​​to trigger corresponding interactive functions. Because the measured value is physical pressure, it is not affected by the user's hair, sweat, or surface dirt, effectively reducing the false touch rate and improving the accuracy of the interaction.
