Detailed Implementation

[0045] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.

[0046] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0047] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, an assembly or device comprising one or more components is not limited to the one or more components listed, but may optionally also include one or more components not listed but inherent to the exemplified product, or one or more components that it should have based on the described function.

[0048] Please see Figure 1 and Figure 2 This application provides an earphone 100. The earphone 100 includes, but is not limited to, clip-on earphones, TWS (True Wireless Stereo) earphones, ear-hook earphones, and behind-the-ear earphones. This embodiment uses the earphone 100 applied to clip-on earphones as an example.

[0049] Please see Figure 1 and Figure 2 The earphone 100 includes a power supply unit 10, a sound output unit 30, a connector 20, and at least one first sensor 40 connected in sequence.

[0050] The power supply unit 10 is also referred to as a battery bead, or comfort bead, or power bead, or power system, or power supply module. The power supply unit 10 has a built-in battery that provides power support for the earphone 100.

[0051] The sound output component 30 is also referred to as a sound output ball. The sound output component 30 is the acoustic module or speaker module of the headphone 100. The sound output ball includes a sound cavity unit that transmits sound through air conduction or bone conduction technology. Furthermore, the open-back design avoids blocking the ear canal while maintaining ambient sound perception.

[0052] Connector 20 is also known as a C-bridge / elastic arm. Connector 20 is made of flexible memory fiber or TPU material and is fixed to the auricle or ear cartilage by elastic clamping force to ensure a stable fit while avoiding pressure.

[0053] When worn, the connector 20 spans the longitudinal axis of the auricle, the sound output component 30 is located inside the auricle, and the power supply component 10 is located outside the auricle.

[0054] In conventional technology, the outer surface of the earphone 100 is smooth, making it difficult to perceive the boundary when a fingertip slides over it, and the operator cannot accurately locate the touch position when blindly touching. Based on this, this application provides an earphone 100 that effectively avoids accidental touches and improves the accuracy of blind touch operation.

[0055] This application provides a touch surface on the outer surface of the earphone 100, with a clearly tactile boundary line between it and the overall surface. This touch surface can be located on any one or more of the outer surfaces of the power supply unit 10, the sound output unit 30, and the connector 20. The touch surface has at least one sensor for recognizing touch control, press control, or pressure touch to trigger the earphone 100's operating mode. The earphone's operating modes include at least one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, and switch between audio / video playback.

[0056] Please see Figure 1 and Figure 2 In the earphone 100 provided in Embodiment 1 of this application, the touch surface is disposed on the outer surface of the power supply component 10. The earphone 100 provided in Embodiment 1 will be specifically illustrated below with reference to the accompanying drawings.

[0057] Please see Figure 1 and Figure 2 The power supply component 10 includes a power housing 11. The outer surface of the power housing 11 includes a first integral surface 111 and at least one first touch surface 112 intersecting with the first integral surface 111.

[0058] Please see Figure 1 and Figure 2 The first integral surface 111 is the main surface of the power supply housing 11. The first touch surface 112 is a partial surface on the power supply housing 11. The number of first touch surfaces 112 can be one or more.

[0059] The first touch surface 112 and the first integral surface 111 have a clearly tactile boundary line. For ease of explanation, this application defines the boundary line between the first touch surface 112 and the first integral surface 111 as the first boundary line 116. This application does not make specific limitations on the trajectory, shape, etc. of the first boundary line 116.

[0060] This application does not specify the size or shape of the first touch surface 112. Optionally, the first touch surface 112 may be rectangular, circular, or elliptical, etc.

[0061] Please see Figure 1 and Figure 2The first touch surface 112 and the first integral surface 111 are interconnected as one unit. For example, the first touch surface 112 and the first integral surface 111 are made of the same material. The first touch surface 112 and the first integral surface 111 are intersecting surfaces formed from the same substrate. As another example, the material of the first touch surface 112 is different from that of the first integral surface 111, and the first touch surface 112 and the first integral surface 111 are interconnected as one unit through injection molding or similar methods. Furthermore, by setting the tactile feel of the material of the first touch surface 112 to be different from that of the first integral surface 111, it is easier for the operator to identify the first touch surface 112 by blind touch.

[0062] The number of the first sensor 40 may be one or more.

[0063] The first sensor 40 is used to interact with the operator's hand to collect touch or press signals and transmit the collected touch or press signals to the controller. The controller controls the current working mode of the headset 100 according to the collected touch or press signals.

[0064] The first sensor 40 is, but is not limited to, any one or more of capacitive sensors, pressure sensors, etc.

[0065] When the first sensor 40 is a capacitive sensor, when a finger touches the capacitive sensor, the capacitance of the capacitive sensor electrode changes. The controller detects the change in charge of the capacitive sensor, and the digital-to-analog converter converts the change in charge into a digital signal. The algorithm filters out noise in the digital signal and outputs a command signal to control the current working mode of the headset 100 to be any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between playing audio / video.

[0066] When the first sensor 40 is a pressure detection sensor, the pressure detection sensor detects the deformation caused by pressing to obtain the change in charge. The digital-to-analog converter converts the change in charge into a digital signal, filters the noise in the digital signal through an algorithm, and outputs a command signal to control the current working mode of the headset 100 to be any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, switch between playing audio / video, etc.

[0067] Further optionally, the sensing element of the pressure-sensing sensor may include, but is not limited to, piezoelectric ceramic, to obtain the change in charge by detecting the compression deformation.

[0068] Further optionally, the sensing element of the pressure sensing sensor may include, but is not limited to, two capacitor plates. The distance between the two capacitor plates changes under pressure deformation, causing a change in capacitance and thus acquiring the change in charge.

[0069] Pressure-sensing sensors can also amplify and sample the changes in charge caused by pressure deformation to determine different pressure levels.

[0070] Optionally, at least a portion of the first sensor 40 is disposed on the first touch surface 112. Specifically, a portion of the first sensor 40 is disposed on the first touch surface 112.

[0071] Optionally, at least a portion of the first sensor 40 is disposed on or directly opposite the first touch surface 112. Specifically, a portion of the first sensor 40 is directly opposite the first touch surface 112; or, another portion of the first sensor 40 is directly opposite the first touch surface 112.

[0072] For details, please refer to Figure 3 The power supply housing 11 includes a first end housing 113 and a first peripheral housing 114. The first peripheral housing 114 is disposed around the first end housing 113 and forms a power supply housing space.

[0073] Please see Figure 3 A first sensor 40 is disposed within the power supply housing space, directly facing the first touch surface 112, so that when the operator's hand operates on the first touch surface 112, the first sensor 40 can sense the operator's hand operation and perform targeted mode switching. The first end shell 113 includes a first touch surface 112 and a first inner surface 115 disposed opposite to each other. The first sensor 40 can be disposed directly facing the first inner surface 115.

[0074] The first touch surface 112 is not smoothly connected to the first integral surface 111. The operator can easily find the location of the first touch surface 112 by blind touch on the outer surface of the power supply component 10, thereby avoiding accidental touches and improving the accuracy of touch / pressure-sensitive position recognition.

[0075] Please see Figure 1 and Figure 2 The sound output component 30 and the power supply component 10 are spaced apart.

[0076] Please see Figure 1 and Figure 2 The connector 20 is connected between the power supply component 10 and the sound output component 30.

[0077] This application provides an earphone 100, which includes a power supply component 10, at least one first sensor 40, a sound output component 30, and a connector 20. The power supply component 10 includes a power housing 11, the outer surface of which includes a first integral surface 111 and at least one first touch surface 112 intersecting with the first integral surface 111. At least a portion of the first sensor 40 is disposed on or directly opposite the first touch surface 112. The sound output component 30 is spaced apart from the power supply component 10. The connector 20 connects the power supply component 10 and the sound output component 30. By providing a clearly defined first touch surface 112 on the outer surface of the power housing 11, and by placing the first sensor 40 at the location of the first touch surface 112, the location of the first sensor 40 can be accurately determined without blind touch, effectively avoiding accidental touch and improving the accuracy of blind touch operation.

[0078] This application does not specifically limit the first integral surface 111 and the first touch surface 112. The first integral surface 111 and the first touch surface 112 are illustrated below with reference to the accompanying drawings.

[0079] For the first alternative implementation, please refer to Figure 4 The first integral surface 111 includes a flat surface, and the first touch surface 112 includes a concave surface or a convex surface.

[0080] For example, the first overall surface 111 is a flat surface, and the first touch surface 112 is a convex surface that protrudes from the first overall surface 111, or a concave surface that is recessed from the first overall surface 111, so that the first touch surface 112 intersects with the first overall surface 111 and has a clear first dividing line 116 for touch, so that the operator can accurately identify the location of the first touch surface 112 on the outer surface of the earphone 100 by blind touch, so as to interact with the first sensor 40 and switch the working mode of the earphone 100.

[0081] For the second alternative implementation, please refer to... Figure 3 The first integral surface 111 includes an arc surface or a cylindrical surface, and the first touch surface 112 includes a plane or a concave surface.

[0082] For example, the first integral surface 111 is an arc surface or a cylindrical surface. The outer surface of the power supply component 10 is a cylindrical surface or an elliptical cylindrical surface. The first touch surface 112 is a plane relative to the first integral surface 111, or a concave surface that is recessed relative to the first integral surface 111, so that the first touch surface 112 intersects with the first integral surface 111 and has a clear first tactile dividing line 116, so that the operator can accurately identify the location of the first touch surface 112 on the outer surface of the earphone 100 by blind touch, so as to interact with the first sensor 40 to switch the working mode of the earphone 100.

[0083] This application does not specify the correspondence between the number of first touch surfaces 112 and the number of first sensors 40.

[0084] For the first alternative implementation, please refer to Figure 5 and Figure 6 The number of first touch surfaces 112 is one, and the number of first sensors 40 can be multiple, with all the first sensors 40 positioned directly opposite the first touch surface 112. The multiple first sensors 40 can enable the first touch surface 112 to form multiple pressing areas, and the operator can control the headphones 100 to switch to different working modes by operating different pressing areas 1120 with their hand.

[0085] Alternatively, each pressing area 1120 may be provided with one first sensor 40; or, each pressing area 1120 may be provided with multiple first sensors 40. The first sensors 40 corresponding to different pressing areas 1120 can operate independently.

[0086] Specifically, for example, the first touch surface 112 has upper and lower pressing areas 1120. The operator operates the upper pressing area 1120 to control the headset 100 to switch to a first playback mode. The operator operates the lower pressing area 1120 to control the headset 100 to switch to a second playback mode. The first working mode is any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio / video playback. The second working mode is any other one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio / video playback.

[0087] Specifically, for example, the first touch surface 112 has four pressing areas 1120: top, bottom, left, and right. The operator operates the top pressing area 1120 to control the headset 100 to switch to a first playback mode. The operator operates the bottom pressing area 1120 to control the headset 100 to switch to a second playback mode. The operator operates the left pressing area 1120 to control the headset 100 to switch to a third playback mode. The operator operates the right pressing area 1120 to control the headset 100 to switch to a fourth playback mode. The first, second, third, and fourth working modes are any four different functions: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, and switch between audio / video playback.

[0088] The above is just an example of the number of press areas 1120; the number of press areas 1120 can also be other numbers.

[0089] For the second alternative implementation, please refer to... Figure 7 and Figure 8 There are two first touch surfaces 112, which are referred to as the first sub-touch surface 1121 and the second sub-touch surface 1122, respectively. The first sub-touch surface 1121 and the second sub-touch surface 1122 can be arranged adjacent to each other or opposite to each other, so that the operator can apply pressure to the first sub-touch surface 1121 and the second sub-touch surface 1122 with two fingers respectively to complete the pressing action.

[0090] Please see Figure 7 At least one of the first touch surfaces 112 includes a first sub-touch surface 1121 and a second sub-touch surface 1122. The first sub-touch surface 1121 and the second sub-touch surface 1122 are disposed opposite to each other.

[0091] Specifically, the first sub-touch surface 1121 may face one or more first sensors 40; the second sub-touch surface 1122 may not face the first sensor 40, that is, the first sub-touch surface 1121 is a pressure-sensitive surface, and the second sub-touch surface 1122 is a mating surface that is easy to press. By pressing the first touch surface 112, the current working mode of the earphone 100 can be switched.

[0092] Please see Figure 7 At least one of the first sensors 40 includes a first sub-sensor 41. The first sub-sensor 41 is disposed on or directly opposite the first sub-touch surface 1121.

[0093] Specifically, the second sub-touch surface 1122 may face one or more first sensors 40; the first sub-touch surface 1121 may not face the first sensor 40, meaning the second sub-touch surface 1122 is a pressure-sensitive surface, and the first sub-touch surface 1121 is a mating surface that is easy to press. By pressing the second sub-touch surface 1122, the current working mode of the earphone 100 can be switched.

[0094] Please see Figure 8 At least one of the first sensors 40 includes a first sub-sensor 41. The first sub-sensor 41 is disposed on or directly opposite the second sub-touch surface 1122.

[0095] Optionally, the first sub-touch surface 1121 may face one or more first sensors 40; the second sub-touch surface 1122 may face one or more first sensors 40; that is, the first sub-touch surface 1121 and the second sub-touch surface 1122 are pressure-sensitive surfaces. Further optionally, the first sensors 40 corresponding to different sub-touch surfaces may work independently or synchronously.

[0096] Please see Figure 9 At least one of the first sensors 40 includes a first sub-sensor 41 and a second sub-sensor 42. The first sub-sensor 41 is disposed on or directly opposite the first sub-touch surface 1121. The second sub-sensor 42 is disposed on or directly opposite the second sub-touch surface 1122.

[0097] The earphone 100 also includes a controller (not shown). The controller is electrically connected to the first sub-sensor 41 and the second sub-sensor 42. The controller is used to determine the operating mode of the earphone 100 based on the signal from the first sub-sensor 41 and / or the signal from the second sub-sensor 42, that is, to switch the current operating mode of the earphone 100.

[0098] The working modes of the headphones 100 include, but are not limited to, any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, switch between audio / video playback, etc.

[0099] In this embodiment, the controller determines that the current operating mode of the earphone 100 is switched to the first operating mode by detecting that the pressure sensed by the first sub-sensor 41 is greater than a first preset pressure value, and the pressure sensed by the second sub-sensor is less than a second preset pressure value. In other words, when the operator presses the first sub-touch surface 1121 firmly with their finger, and the operator lightly presses or does not press the second sub-touch surface 1122, the current operating mode of the earphone 100 can be switched to the first operating mode. The second preset pressure value is less than the first preset pressure value.

[0100] In this embodiment, the controller detects that the pressure sensed by the second sub-sensor 42 is greater than a first preset pressure value. If the pressure sensed by the first sub-sensor is less than a second preset pressure value, the controller determines that the current operating mode of the earphone 100 is switched to the second operating mode. In other words, if the operator presses the second sub-touch surface 1122 firmly with their finger, or if the operator lightly presses or does not press the first sub-touch surface 1121, the current operating mode of the earphone 100 can be switched to the second operating mode.

[0101] In this embodiment, the controller determines that the current operating mode of the earphone 100 is switched to the third operating mode by detecting that the sensing pressure of the first sub-sensor 41 is less than a second preset pressure value. If the sensing pressure of the second sub-sensor is also less than the second preset pressure value, the controller can switch the current operating mode of the earphone 100 to the third operating mode. In other words, by lightly pressing the first sub-touch surface 1121 and then the second sub-touch surface 1122, the current operating mode of the earphone 100 can be switched to the third operating mode.

[0102] In this embodiment, the controller determines that the current operating mode of the earphone 100 is switched to the fourth operating mode by detecting that the pressure sensed by the first sub-sensor 41 is greater than a first preset pressure value, and the pressure sensed by the second sub-sensor is greater than the first preset pressure value. In other words, when the operator presses the first sub-touch surface 1121 firmly with their finger, and the operator presses the second sub-touch surface 1122 firmly with their finger, the current operating mode of the earphone 100 can be switched to the fourth operating mode.

[0103] The first working mode, the second working mode, the third working mode, and the fourth working mode are any four different functions such as play, pause, exit playback, answer the phone, hang up the phone, increase volume, decrease volume, and switch between audio / video playback.

[0104] This application does not limit the specific structure of the first sensor 40. The following is an example of the structure of the first sensor 40 with reference to the accompanying drawings.

[0105] For the first alternative implementation, please refer to Figure 10 The first sensor 40 includes a pressure sensing element 401. The pressure sensing element 401 includes, but is not limited to, a piezoresistive element. The piezoresistive element includes, but is not limited to, a zinc oxide (ZnO) piezoresistive element, a silicon carbide (SiC) piezoresistive element, etc.

[0106] A pressure sensing element 401 is disposed inside the power supply housing 11. The sensing surface of the pressure sensing element 401 faces the first touch surface 112. The pressure sensing element 401 is used to sense the pressure applied to the first touch surface 112.

[0107] Specifically, when the operator presses the first touch surface 112 with their finger, the first touch surface 112 undergoes a slight deformation to transmit the pressing pressure to the sensing surface of the pressure sensing element 401, so that the pressure sensing element 401 senses the pressing pressure of the operator's finger pressing the first touch surface 112.

[0108] Optional, please refer to Figure 10 The power supply housing 11 includes a first end shell 113. The first end shell 113 includes a first touch surface 112 and a first inner surface 115 disposed opposite to each other. The sensing surface of the pressure sensing element 401 contacts the first inner surface 115. This ensures that when an operator presses their finger on the first touch surface 112, the pressure applied by the operator's finger is completely transmitted to the pressure sensing element 401 through the slight deformation of the first touch surface 112 (first end shell 113), thus avoiding a decrease in the sensitivity of the pressure sensing element 401 to finger pressure due to a gap between the sensing surface of the pressure sensing element 401 and the first inner surface 115. In other words, by designing the sensing surface of the pressure sensing element 401 to contact the first inner surface 115, the sensitivity of the pressure sensing element 401 to finger pressure is improved.

[0109] Alternatively, the sensing surface of the pressure sensing element 401 may be in close contact with the first inner surface 115, that is, the sensing surface of the pressure sensing element 401 may be in close contact with the first end shell 113, so as to improve the sensing sensitivity of the pressure sensing element 401 to the pressure of a finger.

[0110] Optionally, the earphone 100 further includes a controller. The controller includes, but is not limited to, a main control chip (main control IC) disposed inside the earphone 100. The controller is electrically connected to the pressure sensing element 401 (or pressure-sensitive device). The controller is used to determine the operating mode of the earphone 100 according to the pressure sensing element 401, that is, to switch the operating mode of the earphone 100 according to the pressure sensing element 401.

[0111] For example, when the pressure applied to the pressure sensing element 401 is between F1 and F2, the controller switches the current operating mode of the headphones 100 to the first operating mode. When the pressure applied to the pressure sensing element 401 is between F2 and F3, the controller switches the current operating mode of the headphones 100 to the second operating mode. When the pressure applied to the pressure sensing element 401 is between F3 and F4, the controller switches the current operating mode of the headphones 100 to the third operating mode.

[0112] By closely attaching the sensing surface of the pressure sensing element 401 to the first inner surface 115 of the first end shell 113, the pressure level of the pressure sensing element 401 sensing the finger pressure is improved. The controller can control the earphone 100 to work in different working modes according to the different pressure levels of the finger pressure.

[0113] Specifically, when the first touch surface 112 of the first end shell 113 is pressed by the operator, the first touch surface 112 of the first end shell 113 experiences micro-strain due to external force (micro-strain occurs towards the side where the pressure sensing element 401 is located), and this micro-strain is transmitted to the pressure sensing element 401. The pressure sensing element 401 identifies the micro-strain and converts it into an electrical signal, which is then transmitted to the main control chip for operation determination. Different functions are triggered by different pressing pressure (such as light pressing to adjust the volume, and hard pressing to switch modes).

[0114] Further optional information can be found in [link to relevant documentation]. Figure 10 The earphone 100 also includes a first elastic buffer 12 and a first bracket 13 disposed within the power supply housing 11. The first elastic buffer 12 is disposed between the first bracket 13 and the pressure sensing element 401, such that the sensing surface of the pressure sensing element 401 abuts against the first inner surface 115.

[0115] The first bracket 13 is fixed relative to the power supply housing 11, providing support. The first elastic buffer 12 is pressed between the pressure sensing element 401 and the first bracket 13, ensuring that the sensing surface of the pressure sensing element 401 is in close contact with the first inner surface 115 of the first end housing 113. In other words, the first elastic buffer 12 and the first bracket 13 provide an interference fit between the pressure sensing element 401 and the first end housing 113.

[0116] The first elastic buffer 12 includes, but is not limited to, silicone, rubber, foam, thermoplastic elastomer, or thermoplastic polyurethane.

[0117] When the first touch surface 112 of the first end shell 113 is pressed, the first end shell 113 undergoes a slight deformation toward the side where the pressure sensing element 401 is located, and transmits the slight deformation to the pressure sensing element 401. The first elastic buffer 12 not only keeps the sensing surface of the pressure sensing element 401 in close contact with the first end shell 113, improving the sensitivity of the pressure sensing element 401 to slight deformation, but also provides a buffer space to avoid damage to the pressure sensing element 401 caused by excessive pressing pressure.

[0118] Further optional information can be found in [link to relevant documentation]. Figure 10The thickness of the area of ​​the first end shell 113 directly opposite the pressure sensing element 401 is less than the thickness of the area of ​​the first end shell 113 not directly opposite the pressure sensing element 401. In other words, the position of the first end shell 113 directly opposite the pressure sensing element 401 is thinned, making the first end shell 113 more prone to slight deformation under the pressure of the operator's finger, thus improving the conversion efficiency of pressure into deformation.

[0119] Further optional information can be found in [link to relevant documentation]. Figure 10 The pressure sensing element 401 is hollow in all directions, that is, there is no blocking support to prevent the first end shell 113 from undergoing slight deformation in the direction perpendicular to the sensing surface of the pressure sensing element 401. This makes it easier for the first end shell 113 to undergo slight deformation under the pressure of the operator's finger, thereby improving the conversion efficiency of pressing force into deformation.

[0120] Optional, please refer to Figure 10 The power supply housing 11 also includes a first peripheral shell 114. The first peripheral shell 114 surrounds the periphery of the first end shell 113. The first end shell 113 and the first peripheral shell 114 are interconnected as an integral structure, that is, the first end shell 113 and the first peripheral shell 114 are sealed together to ensure the appearance integrity of the earphone 100.

[0121] The first end shell 113 and the first peripheral shell 114 are interconnected as a single unit. For example, the first end shell 113 and the first peripheral shell 114 are made of the same material. The first end shell 113 and the first peripheral shell 114 are intersecting surfaces formed from the same substrate. As another example, the first end shell 113 is made of a different material than the first peripheral shell 114, and the first end shell 113 and the first peripheral shell 114 are interconnected as a single unit through injection molding or the like. Furthermore, by setting the tactile feel of the material of the first end shell 113 to be different from that of the first peripheral shell 114, it is easier for the operator to blindly identify the first touch surface 112 on the first end shell 113.

[0122] In one alternative implementation, please refer to Figure 11 The first peripheral shell 114 is a hard plastic shell, while the first end shell 113 is a soft plastic shell. In other words, the hardness of the first peripheral shell 114 is much greater than that of the first end shell 113. The first peripheral shell 114 possesses better hardness and rigidity to protect the internal components. The first end shell 113 is a soft plastic shell so that it can easily undergo slight deformation under the pressure of the operator's fingers, improving the efficiency of converting pressure into deformation.

[0123] The material of the first week's side shell 114 includes, but is not limited to, acrylonitrile-butadiene-styrene (ABS) or polycarbonate (PC).

[0124] The material of the first end shell 113 includes, but is not limited to, thermoplastic elastomer, thermoplastic polyurethane, silicone, rubber, or leather.

[0125] In this embodiment, the first side shell 114 and the first end shell 113 can be integrally injection molded to form a soft-hard combination structure, which has good hardness and rigidity to protect the internal components, and also makes it easy for the first end shell 113 to produce micro-deformation under the operator's finger pressure, thereby improving the conversion efficiency of pressing force into deformation.

[0126] For another alternative implementation, please refer to Figure 10 Both the first peripheral shell 114 and the first end shell 113 are made of rigid plastic. The material of the rigid plastic shell includes, but is not limited to, acrylonitrile-butadiene-styrene (ABS) or polycarbonate (PC).

[0127] In this embodiment, the first side shell 114 and the first end shell 113 can be integrally injection molded, which has good hardness and rigidity to protect the internal components. The first end shell 113 is thinned, which also makes it easier for the first end shell 113 to undergo micro-deformation under the operator's finger pressure, thereby improving the conversion efficiency of pressure into deformation.

[0128] For the second alternative implementation, please refer to... Figure 12 The first sensor 40 includes a pressure sensing element 401. The pressure sensing element 401 includes, but is not limited to, a polymer-based piezoresistor. The first sensor 40 is disposed on the first touch surface 112.

[0129] The polymer-based varistor includes a polymer (such as silicone rubber, polyester, thermoplastic polyurethane) substrate and conductive particles (such as carbon black, carbon nanotubes, metal particles, graphene sheets) dispersed in the polymer substrate. When pressure is applied to the sensing surface of the pressure sensing element 401, the contact between the conductive particles increases and the resistance decreases, thereby detecting the pressing pressure applied by the operator on the sensing surface of the pressure sensing element 401.

[0130] Optional, please refer to Figure 12 The power supply housing 11 includes a first end shell 113. The first end shell 113 includes a first touch surface 112 and a first inner surface 115 disposed opposite to each other. A first sensor 40 may be disposed on the first end shell 113.

[0131] Specifically, the first end shell 113 includes a polymer (such as silicone rubber, polyester, thermoplastic polyurethane) substrate and conductive particles (such as carbon black, carbon nanotubes, metal particles, graphene sheets) dispersed in the polymer substrate. When an operator applies pressure to the first end shell 113, the contact between the conductive particles inside the first end shell 113 increases, and the resistance decreases, thereby detecting the pressing pressure applied by the operator on the sensing surface of the pressure sensing element 401.

[0132] Optionally, the earphone 100 further includes a controller. The controller includes, but is not limited to, a main control chip (main control IC) disposed inside the earphone 100. The controller is electrically connected to the pressure sensing element 401 (or pressure-sensitive device). The controller is used to determine the magnitude of the sensed pressure based on the decrease in resistance of the pressure sensing element 401, and to switch the operating mode of the earphone 100 according to the magnitude of the pressure applied by the pressure sensing element 401. In other words, the controller can control the earphone 100 to operate in different operating modes according to different pressure levels applied by the finger.

[0133] Further, please refer to Figure 12 The earphone 100 also includes a second bracket 14, which is in close contact with the first inner surface 115 of the first end shell 113. When the operator applies pressure to the first end shell 113, the contact between the conductive particles inside the first end shell 113 increases, thereby improving the sensitivity of pressure sensing.

[0134] In this embodiment, the first end shell 113 can be used as a pressure sensing element 401. Compared with the pressure sensing element 401 provided in the first optional embodiment, this application does not require additional pressure-sensitive resistor or additional first buffer, reducing the number of structures required and the space occupied. The pressure is applied directly to the pressure sensing element 401, which can further improve the sensitivity of pressure sensing.

[0135] For a third alternative implementation, please refer to... Figure 13 The first sensor 40 includes a first conductive sheet 411 and a second conductive sheet 412 disposed opposite to each other. At least a portion of the first conductive sheet 411 is directly opposite the first touch surface 112. The distance between the first conductive sheet 411 and the second conductive sheet 412 decreases under pressure.

[0136] The second conductive sheet 412 is located on the side of the first conductive sheet 411 opposite to the first touch surface 112. There is a small distance between the first conductive sheet 411 and the second conductive sheet 412. The first conductive sheet 411 and the second conductive sheet 412 form a capacitor. When the first touch surface 112 is pressed, the distance between the first conductive sheet 411 and the second conductive sheet 412 decreases, the capacitance of the first sensor 40 changes, and consequently the amount of charge changes. The magnitude of the pressing pressure on the first touch surface 112 can be identified by detecting the change in charge.

[0137] The first conductive sheet 411 can be an exposed copper area on the flexible circuit board, and the second conductive sheet 412 can be an exposed copper area on the flexible circuit board.

[0138] Optional, please refer to Figure 13 The power supply housing 11 includes a first end shell 113. The first end shell 113 includes a first touch surface 112 and a first inner surface 115 disposed opposite to each other. A first conductive sheet 411 is attached to the first inner surface 115. A second conductive sheet 412 may be fixedly disposed within the first end shell 113. For example, the second conductive sheet 412 may be disposed on a first bracket 13. The first end shell 113 is a soft rubber shell.

[0139] When the first touch surface 112 of the first end shell 113 is pressed, since the first end shell 113 is a soft rubber shell, it facilitates the movement of the first conductive sheet 411 toward the second conductive sheet 412. The distance between the first conductive sheet 411 and the second conductive sheet 412 decreases, and the capacitance of the first sensor 40 changes, resulting in a change in the amount of charge. The magnitude of the pressing pressure on the first touch surface 112 can be identified by detecting the change in the amount of charge.

[0140] The earphone 100 also includes a controller. The controller is electrically connected to the first conductive piece 411 and the second conductive piece 412. The controller determines the operating mode of the earphone 100 based on the capacitance value between the first conductive piece 411 and the second conductive piece 412.

[0141] Specifically, the controller can detect the change in charge based on the change in capacitance between the first conductive sheet 411 and the second conductive sheet 412, and then identify the magnitude of the pressing pressure on the first touch surface 112 based on the change in charge, and switch the working mode of the earphone 100 according to different pressing pressures.

[0142] For example, when the pressure applied to the pressure sensing element 401 is between F1 and F2, the controller switches the current operating mode of the headphones 100 to the first operating mode. When the pressure applied to the pressure sensing element 401 is between F2 and F3, the controller switches the current operating mode of the headphones 100 to the second operating mode. When the pressure applied to the pressure sensing element 401 is between F3 and F4, the controller switches the current operating mode of the headphones 100 to the third operating mode.

[0143] In conjunction with any of the aforementioned alternative implementation methods, please refer to Figure 14 The earphone 100 also includes the aforementioned controller 70 and feedback device 15.

[0144] The controller 70 is electrically connected to the first sensor 40 and the feedback device 15. The controller 70 is also used to control the feedback device 15 to generate a corresponding feedback signal according to the signal characteristics of the first sensor 40, so that the operator knows that the controller 70 has recognized the operator's touch press operation, and avoids the operator from repeatedly pressing because he does not know whether the controller 70 has recognized the press operation.

[0145] The feedback device 15 includes a sound-emitting device and / or a vibration device.

[0146] For example, the feedback device 15 includes a sound-emitting device, such as an acoustic module. After receiving a pressing pressure detected by the first sensor 40, the controller 70 controls the acoustic module to generate a feedback sound signal.

[0147] For another example, the feedback device 15 includes a vibration device, such as a vibration motor. After receiving the pressing force identified by the first sensor 40, the controller 70 controls the vibration motor to generate a feedback vibration signal.

[0148] For another example, the feedback device 15 includes a sound-emitting device and a vibration device. The sound-emitting device is, for example, an acoustic module. The vibration device is, for example, a vibration motor. After receiving the pressing pressure identified by the first sensor 40, the controller 70 controls the acoustic module to generate a feedback sound signal and / or controls the vibration motor to generate a feedback vibration signal.

[0149] Depending on the pressure applied, the controller 70 can send different feedback signals. In other words, the feedback signals can correspond one-to-one with the pressure applied by the first sensor 40.

[0150] Optional, please refer to Figures 15a-15c The first touch surface 112 is provided with a touch recognition structure 1123.

[0151] The touch recognition structure 1123 includes, but is not limited to, at least one of the following: raised bulge, concave dot, concave strip, raised dot, raised rib, fingerprint pattern, texture structure, and logo. When the operator operates, they cannot accurately press the location of the first sensor 40. This embodiment addresses this by setting the touch recognition structure 1123 at the operation pressing location (first touch surface 112), such as a raised bulge, concave dot, concave strip, raised dot, raised rib, fingerprint pattern, texture structure, or logo, so that the operator can accurately press the desired location.

[0152] Optional, please refer to Figure 16 The number of the first sensors 40 is multiple. The first touch surface 112 includes multiple pressing areas 1120. Each pressing area 1120 faces at least one of the first sensors 40. The multiple first sensors 40 enable the first touch surface 112 to form multiple pressing areas 1120, and the operator's hand controls the headphones 100 to switch to different working modes by operating different pressing areas 1120.

[0153] Multiple first sensors 40 can be arranged in an array, that is, the first touch surface 112 faces the array of first sensors 40. Correspondingly, multiple pressing areas 1120 are also arranged in a row.

[0154] Alternatively, each pressing area 1120 may be provided with one first sensor 40; or, each pressing area 1120 may be provided with multiple first sensors 40. The first sensors 40 corresponding to different pressing areas 1120 can operate independently.

[0155] The earphone 100 also includes a controller 70. The controller 70 is electrically connected to multiple sensors. The controller 70 is used to determine the operating mode of the earphone 100 based on the signals of the first sensor 40 corresponding to different pressing areas 1120, that is, to switch the current operating mode of the earphone 100 based on the pressure signals detected by the first sensor 40 corresponding to different pressing areas 1120.

[0156] Specifically, for example, the first touch surface 112 has upper and lower pressing areas 1120. The operator operates the upper pressing area 1120 to control the headset 100 to switch to a first playback mode. The operator operates the lower pressing area 1120 to control the headset 100 to switch to a second playback mode. The first working mode is any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio / video playback. The second working mode is any other one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio / video playback.

[0157] For specific examples, please refer to Figure 16The first touch surface 112 has four pressing areas 1120: top, bottom, left, and right. The operator operates the top pressing area 1120 to control the headset 100 to switch to a first playback mode. The operator operates the bottom pressing area 1120 to control the headset 100 to switch to a second playback mode. The operator operates the left pressing area 1120 to control the headset 100 to switch to a third playback mode. The operator operates the right pressing area 1120 to control the headset 100 to switch to a fourth playback mode. The first, second, third, and fourth working modes are any four different functions: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, and switch between audio / video playback.

[0158] Optional, please refer to Figure 16 Different touch recognition structures 1123 can be set on different pressing areas 1120 so that the operator can identify the location of different pressing areas 1120 when touching blindly.

[0159] The above is an embodiment in which the touch surface is provided on the outer surface of the power supply component 10. Of course, the touch surface of the earphone 100 can also be provided on the connector 20. The following is an example of the earphone 100 having a touch surface on both the power supply component 10 and the connector 20.

[0160] For any of the aforementioned implementation methods, please refer to [link / reference]. Figure 17 The connector 20 further includes a second integral surface 211 and at least one second touch surface 212 intersecting with the second integral surface 211.

[0161] Please see Figure 17 The earphone 100 also includes at least one second sensor 50. At least a portion of the second sensor 50 is disposed on the second touch surface 212; or, at least a portion of the second sensor 50 is directly opposite the second touch surface 212.

[0162] The second overall surface 211 is the main surface of the connector 20. The second touch surface 212 is a partial surface on the connector 20. The number of second touch surfaces 212 can be one or more.

[0163] The second touch surface 212 and the second integral surface 211 have a clearly tangible boundary line. For ease of explanation, this application defines the boundary line between the second touch surface 212 and the second integral surface 211 as the second boundary line. This application does not impose specific limitations on the trajectory, shape, etc. of the second boundary line.

[0164] This application does not specify the size or shape of the second touch surface 212. Optionally, the second touch surface 212 may be rectangular, circular, or elliptical, etc.

[0165] The second touch surface 212 and the second integral surface 211 are interconnected as one unit. For example, the second touch surface 212 and the second integral surface 211 are made of the same material. The second touch surface 212 and the second integral surface 211 are intersecting surfaces formed from the same substrate. As another example, the material of the second touch surface 212 is different from that of the second integral surface 211, and the second touch surface 212 and the second integral surface 211 are interconnected as one unit through injection molding or the like. Furthermore, by setting the tactile feel of the material of the second touch surface 212 to be different from that of the second integral surface 211, it is easier for the operator to identify the second touch surface 212 by blind touch.

[0166] The number of the second sensor 50 can be one or more.

[0167] The second sensor 50 is used to interact with the operator's hand to collect touch or press signals and transmit the collected touch or press signals to the controller 70. The controller 70 controls the current working mode of the headset 100 according to the collected touch or press signals.

[0168] The second sensor 50 is, but is not limited to, any one or more of capacitive sensors, pressure sensors, etc. All embodiments of the second sensor 50 may be referred to.

[0169] This application does not specifically limit the second integral surface 211 and the second touch surface 212. The second integral surface 211 and the second touch surface 212 are illustrated below with reference to the accompanying drawings.

[0170] In a first optional embodiment, the second integral surface 211 includes a flat surface, and the second touch surface 212 includes a concave surface or a convex surface.

[0171] For example, the second integral surface 211 is a flat surface, and the second touch surface 212 is a convex surface that protrudes from the second integral surface 211, or a concave surface that is recessed from the second integral surface 211, so that the second touch surface 212 intersects with the second integral surface 211 and has a clear second boundary line with tactile feedback, so that the operator can accurately identify the location of the second touch surface 212 on the outer surface of the earphone 100 by blind touch, so as to interact with the second sensor 50 and switch the working mode of the earphone 100.

[0172] In a second alternative embodiment, the second integral surface 211 includes an arc surface or a cylindrical surface, and the second touch surface 212 includes a plane or a concave surface.

[0173] For example, the second integral surface 211 is an arc surface or a cylindrical surface. The outer surface of the connector 20 is a cylindrical surface or an elliptical cylindrical surface. The second touch surface 212 is a plane relative to the second integral surface 211, or a concave surface that is recessed relative to the second integral surface 211, so that the second touch surface 212 intersects with the second integral surface 211 and has a clear second boundary line with tactile feedback, so that the operator can accurately identify the location of the second touch surface 212 on the outer surface of the earphone 100 by blind touch, so as to interact with the second sensor 50 to switch the working mode of the earphone 100.

[0174] This application does not specify the correspondence between the number of second touch surfaces 212 and the number of second sensors 50.

[0175] In a first optional embodiment, there is one second touch surface 212 and multiple second sensors 50, all of which are positioned directly opposite the second touch surface 212. The multiple second sensors 50 enable the second touch surface 212 to form multiple pressing areas 1120. The operator's hand operates on different pressing areas 1120 to control the headphones 100 to switch to different operating modes.

[0176] For the second alternative implementation, please refer to... Figures 17-19 There are two second touch surfaces 212, which are referred to as the third sub-touch surface 2121 and the fourth sub-touch surface 2122, respectively. The third sub-touch surface 2121 and the fourth sub-touch surface 2122 can be arranged adjacent to each other or opposite to each other, so that the operator can apply pressure to the third sub-touch surface 2121 and the fourth sub-touch surface 2122 with two fingers respectively to complete the pressing action.

[0177] At least one of the second touch surfaces 212 includes a third sub-touch surface 2121 and a fourth sub-touch surface 2122. The third sub-touch surface 2121 and the fourth sub-touch surface 2122 are disposed opposite to each other.

[0178] Please see Figures 17-19 The second sensor 50 includes a third conductive sheet 51 and a fourth conductive sheet 52 disposed opposite to each other. At least a portion of the third conductive sheet 51 is directly opposite the second touch surface 212. The distance between the third conductive sheet 51 and the fourth conductive sheet 52 decreases under pressure. The earphone 100 also includes a controller 70. The controller 70 is electrically connected to the third conductive sheet 51 and the fourth conductive sheet 52. The controller 70 determines the operating mode of the earphone 100 based on the capacitance value between the third conductive sheet 51 and the fourth conductive sheet 52.

[0179] Optionally, at least a portion of the third conductive sheet 51 faces the third sub-touch surface 2121. At least a portion of the fourth conductive element faces the fourth sub-touch surface 2122. A small distance exists between the third conductive sheet 51 and the fourth conductive sheet 52. The third conductive sheet 51 and the fourth conductive sheet 52 form a capacitor. When the third sub-touch surface 2121 and the fourth sub-touch surface 2122 are subjected to pressure, the distance between the third conductive sheet 51 and the fourth conductive sheet 52 decreases, the capacitance of the second sensor 50 changes, and consequently the amount of charge changes. The magnitude of the pressure applied to the third sub-touch surface 2121 and the fourth sub-touch surface 2122 can be identified by detecting the change in charge.

[0180] When the third sub-touch surface 2121 and the fourth sub-touch surface 2122 are pressed, the connector 20, including a soft rubber connector 20, is made of soft rubber to facilitate compression under pressure. This reduces the distance between the third conductive sheet 51 and the fourth conductive sheet 52, causing a change in the capacitance of the second sensor 50, which in turn leads to a change in the amount of charge. By detecting the change in the amount of charge, the magnitude of the pressing pressure applied to the third sub-touch surface 2121 and the fourth sub-touch surface 2122 can be identified.

[0181] The earphone 100 also includes a controller 70. The controller 70 is electrically connected to the third conductive plate 51 and the fourth conductive plate 52. The controller 70 determines the operating mode of the earphone 100 based on the capacitance value between the third conductive plate 51 and the fourth conductive plate 52.

[0182] Specifically, the controller 70 can detect the change in charge based on the change in capacitance between the third conductive sheet 51 and the fourth conductive sheet 52, and then identify the magnitude of the pressing pressure on the third sub-touch surface 2121 and the fourth sub-touch surface 2122 based on the change in charge, and switch the working mode of the earphone 100 according to different pressing pressures.

[0183] For example, when the pressure detected by the second sensor 50 is between F1 and F2, the controller 70 switches the current operating mode of the headphones 100 to the first operating mode. When the pressure detected by the second sensor 50 is between F2 and F3, the controller 70 switches the current operating mode of the headphones 100 to the second operating mode. When the pressure detected by the second sensor 50 is between F3 and F4, the controller 70 switches the current operating mode of the headphones 100 to the third operating mode.

[0184] The above is an embodiment in which the touch surface is provided on the outer surface of the power supply component 10. Of course, the touch surface of the earphone 100 can also be provided separately on the connector 20. The following is an example of the earphone 100 having the touch surface provided on the connector 20, with reference to the accompanying drawings.

[0185] Please see Figures 20-23c Embodiment 2 of this application provides an earphone 100. The earphone 100 includes a sound output component 30, a power supply component 10, a connector 20, and at least one second sensor 50.

[0186] The sound output component 30 and the power supply component 10 are spaced apart.

[0187] The connector 20 is connected between the power supply component 10 and the sound output component 30. The connector 20 includes a connecting housing. The outer surface of the connecting housing includes a second integral surface 211 and at least one second touch surface 212 intersecting with the second integral surface 211.

[0188] At least a portion of the second sensor 50 is disposed on the second touch surface 212; or, at least a portion of the second sensor 50 is directly opposite the second touch surface 212.

[0189] The earphone 100 provided in this embodiment is largely the same as the earphone 100 provided in Embodiment 1, with the main difference being that the touch surface is located on the connector 20. The shape of the second touch surface 212 in this embodiment can refer to the shape of the first touch surface 112 in Embodiment 1. The shape, structure, and position of the second sensor 50 in this embodiment can refer to the shape, structure, and position of the first sensor 40 in Embodiment 1.

[0190] Please see Figure 22 The second sensor 50 includes a third conductive sheet 51 and a fourth conductive sheet 52 disposed opposite to each other. At least a portion of the third conductive sheet 51 is directly opposite the second touch surface 212. The distance between the third conductive sheet 51 and the fourth conductive sheet 52 decreases under pressure. The earphone 100 also includes a controller. The controller is electrically connected to the third conductive sheet 51 and the fourth conductive sheet 52. The controller determines the operating mode of the earphone 100 based on the capacitance value between the third conductive sheet 51 and the fourth conductive sheet 52.

[0191] Optional, please refer to Figures 23a-23c The second touch surface 212 is provided with a touch recognition structure 1123.

[0192] The touch recognition structure 1123 includes, but is not limited to, at least one of the following: raised bulge, concave dot, concave strip, raised dot, raised rib, fingerprint pattern, texture structure, and logo. When the operator operates, they cannot accurately press the location of the second sensor 50. This embodiment addresses this by setting the touch recognition structure 1123 at the operation pressing location (second touch surface 212), such as a raised bulge, concave dot, concave strip, raised dot, raised rib, fingerprint pattern, texture structure, or logo, so that the operator can accurately press the desired location.

[0193] This embodiment can refer to the description of the second sensor 50 in Embodiment 1, which includes the third conductive sheet 51 and the fourth conductive sheet 52 arranged opposite to each other.

[0194] Other implementation methods described in Embodiment 1 above can also be incorporated into this embodiment.

[0195] Of course, the touch surface of the earphone 100 can also be located on the sound output component 30. The following example illustrates how the touch surface of the earphone 100 can be located on the sound output component 30, with reference to the attached diagram.

[0196] In general, the mainstream control methods for clip-on earphones include tapping and physical buttons. Tapping requires significant force to respond, resulting in intermittent or delayed operation and insufficient sensitivity. Prolonged use may cause fatigue, requiring conscious adjustment of tapping force, and some clip-on earphones exhibit touch feedback delays or stuttering, leading to a poor user experience. Dirt and bacteria easily accumulate in the gaps between physical buttons, and sweat can damage the earphones, compromising their appearance. Clip-on earphones are primarily used during exercise, in environments with high levels of sweat and dust. Combined with frequent physical button operations, dirt easily accumulates from finger touches and is difficult to clean. Clip-on earphones are generally compact, with limited internal space. The movable physical buttons require an additional 0.8mm width on each side for sealing, making it difficult to provide sufficient space for a waterproof structure. Touch buttons are prone to accidental operation, and users cannot accurately identify the pressing position when the earphones are worn, leading to malfunctions or unresponsiveness.

[0197] This application incorporates easily operable, pressable features at different locations on the earcup earphone 100 through its design, making it easier for users to operate the press function. For example, features such as grooves or flat surfaces on both sides of the battery holder of the earphone 100, or adding a finger press position at the connecting bridge location.

[0198] The specific internal stacking method involves placing the pressure-sensitive device tightly against the housing at the pressing position, and using cushioning materials such as silicone (first buffer) and an internal support (first support 13) to create an interference fit between the pressure-sensitive device (pressure sensing element 401) and the housing (first end shell 113). When the pressing surface of the earphone 100 is subjected to external force, causing micro-strain in the housing material, this is transmitted to the pressure-sensitive device. The pressure-sensitive device recognizes the micro-strain, converts it into an electrical signal, and transmits it to the main control IC (controller) for operation judgment, thereby better recognizing the pressing action on the pressing part. In addition, to address the issue of control feedback experience, the pressure-sensitive device recognizes the pressure signal and transmits it to the main control IC, which then sends a command to the speaker to emit a specific feedback sound.

[0199] This application reduces accidental touches through a micro-strain triggering function. Furthermore, since the pressure-sensitive device is internal to the earphone 100, no alteration to the exterior is required, thus maintaining the earphone 100's aesthetic consistency. This application implements pressure-sensitive touch functionality through a solution that combines exterior features with internal hardware structure stacking. This avoids accidental touches and lack of feedback common in touch-based solutions while ensuring the integrity of the product's appearance.

[0200] Furthermore, the connecting bridge pressing scheme includes finger pressing positions on both sides of the connecting bridge. The internal stacking is achieved by placing the anode and cathode of capacitors at both ends of the two pressing positions. When the connecting piece 20 is squeezed on both sides of the pressing position, the connecting piece 20 is deformed, thereby changing the distance between the two conductive pieces and altering the capacitance to achieve the pressing function.

[0201] Furthermore, structural features such as raised bumps, raised ribs, and fingerprint patterns are incorporated into the operation and pressing positions to ensure that users can accurately press the sensor, thus solving the problem of users being unable to accurately press the sensor position during operation.

[0202] This application provides a novel interaction scheme for a clip-on earphone 100, which can effectively solve the problem of accidental touch in open-back earphones 100 currently on the market, without compromising the appearance consistency of the earphone 100, and can better meet the ID's requirements for appearance.

[0203] This application places pressure sensors in easily accessible locations on both sides of the comfortable earbud end or the connecting bridge of the earbud 100, where the earbud 100 is easily operated after wearing. The earbud 100's appearance is designed to highlight the pressing operation, ensuring rapid response and minimizing accidental touches when pressed at the designated locations, providing timely feedback. Micro-protrusions or textured structures (such as wave patterns or dot matrix dots) are added to the bottom of the concave surface (first touch surface 112) to allow users to quickly locate the pressing area 1120 by touch during blind operation, improving operational accuracy and enhancing tactile feedback. A pressure sensor array is embedded inside the concave surface (first touch surface 112). Furthermore, different pressing pressures trigger different functions (such as light press to adjust volume, hard press to switch modes), and tactile feedback is provided by a vibration motor or sound feedback by an acoustic module, forming a complete human-computer interaction loop. The concave surface (first touch surface 112) is made of soft silicone or elastic polymer, forming a soft-hard combination structure with the hard shell of the bean body (first peripheral shell 114), which not only improves the pressing comfort, but also enhances the physical feedback of the pressing stroke through deformation.

[0204] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, and such improvements and refinements are also considered to be within the protection scope of this application.
