Detailed Implementation

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 sound-emitting component. The earphone 100 provided in Embodiment 1 will be specifically illustrated below with reference to the accompanying drawings.

[0044] Please see Figure 1 and Figure 2 The earphone 100 includes a sound output component 10 and a touch detection module 20.

[0045] The sound output component 10 is also referred to as a sound output ball. The sound output component 10 is the acoustic module or speaker module of the earphone 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.

[0046] Please see Figure 1 and Figure 2 The sound output component 10 includes a sound output housing 11.

[0047] Please see Figure 2 and Figure 3 The outer surface of the sound-emitting housing 11 includes a first integral surface 111 and at least one first touch surface 112 intersecting with the first integral surface 111.

[0048] The first integral surface 111 is the main surface of the sound-emitting housing 11. The first touch surface 112 is a partial surface on the sound-emitting housing 11. The number of first touch surfaces 112 can be one or more.

[0049] Please see Figure 2 and Figure 3The first touch surface 112 and the first integral surface 111 have a clearly tactile boundary line (edge) to facilitate blind touch identification of the first touch surface 112. 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 edge line 115. This application does not make specific limitations on the trajectory of the first edge line 115.

[0050] 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, elliptical, irregular, or the shape of a fingertip, etc.

[0051] Please see Figure 2 and Figure 3 The 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.

[0052] 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 speaker 10, thereby avoiding accidental touches and improving the accuracy of touch / pressure-sensitive position recognition.

[0053] The touch detection module 20 is located inside the sound output housing 11.

[0054] Please see Figure 2 and Figure 3 The sound-emitting housing 11 includes a front sound-emitting housing 113 and a rear sound-emitting housing 114 that are connected to each other.

[0055] Please see Figure 2 The touch detection module 20 is located inside the sound output rear shell 114.

[0056] At least a portion of the touch detection module 20 is disposed on or directly opposite the first touch surface 112. The touch detection module 20 is used to sense touch operations on the first touch surface 112.

[0057] Optionally, at least a portion of the touch detection module 20 is disposed on the first touch surface 112. For example, a portion of the touch detection module 20 is disposed on the first touch surface 112. As another example, the entire touch detection module 20 is disposed on the first touch surface 112.

[0058] Optionally, at least a portion of the touch detection module 20 is directly opposite the first touch surface 112. For example, a portion of the touch detection module 20 is directly opposite the first touch surface 112. As another example, the entire touch detection module 20 is directly opposite the first touch surface 112.

[0059] Please see Figure 1 and Figure 4 The touch detection module 20 is positioned directly opposite the first touch surface 112, so that when the operator's hand operates on the first touch surface 112, the touch detection module 20 can sense the operator's hand operation and switch to a corresponding mode. The speaker enclosure 114 includes a first touch surface 112 and a first inner surface 116 disposed opposite each other. The touch detection module 20 can be positioned directly opposite the first inner surface 116.

[0060] Please see Figure 4 The touch detection module 20 includes at least one touch detection element 21.

[0061] The number of touch detection elements 21 can be one or more.

[0062] Touch operations include, but are not limited to, any one of touch, swipe, tap, press, etc.

[0063] The touch detection element 21 is used to interact with the operator's hand to collect touch, swipe, tap, or press signals, and transmits the collected touch, swipe, tap, or press signals to the controller. The controller controls the current working mode of the headset 100 according to the collected touch, swipe, tap, or press signals.

[0064] The touch detection element 21 includes, but is not limited to, any one or more of capacitive sensors, pressure sensors, piezoelectric sensors, and resistive sensors.

[0065] Optionally, when the touch detection element 21 is a capacitive sensor, when a finger approaches the capacitive sensor, the capacitance of the sensor's electrodes changes. The controller detects this change in charge, and the digital-to-analog converter converts this change into a digital signal. An algorithm filters noise from the digital signal, outputting a command signal to determine the user's touch operation. Based on the touch operation, the controller adjusts the current operating mode of the headset 100 to any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio and video playback. Different operating modes of the headset 100 can also be controlled based on the number of touches.

[0066] Optionally, the touch detection element 21 may include multiple capacitive sensors distributed along the sliding path. By detecting changes in charge through at least two capacitive sensors along the sliding path, the operator's sliding operation is determined, and the current operating mode of the headset 100 is controlled according to the sliding operation, such as play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio and video playback. Different operating modes of the headset 100 can also be controlled based on different sliding trajectories.

[0067] Optionally, the touch detection element 21 may include a piezoelectric sensor. The piezoelectric sensor generates voltage when subjected to mechanical strain due to vibration, and its output voltage is related to the striking force and frequency. When external pressure is applied, the sensor generates a current signal, reads the analog signal, converts it into a digital value, compares it with a preset threshold, determines the operator's striking action, and controls the current operating mode of the headset 100 according to the striking action, such as play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio / video playback. Different operating modes of the headset 100 can also be controlled based on the number of strikes.

[0068] When the touch detection element 21 is a pressure sensor, the pressure sensor detects the deformation caused by pressing, obtains the change in charge, and the digital-to-analog converter converts the change in charge into a digital signal. An algorithm filters noise from the digital signal, outputs a command signal, determines the operator's pressing operation, and controls the current working mode of the headset 100 according to the pressing operation, such as play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio / video playback. Different working modes of the headset 100 can also be controlled based on the number of presses / duration.

[0069] Further optionally, the sensing element of the pressure sensor may include, but is not limited to, piezoelectric ceramic, to obtain the change in charge by detecting the deformation under pressure.

[0070] Alternatively, the detection element of the pressure 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 capturing the change in charge. The pressure sensor can also amplify and sample the charge change caused by pressure deformation to determine different pressure levels.

[0071] 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.

[0072] This application provides an earphone 100, which includes a sound-emitting component 10 and a touch detection module 20. The sound-emitting component 10 includes a sound-emitting 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. The touch detection module 20 is disposed inside the sound-emitting housing 11, and at least a portion of the touch detection module 20 is disposed on or directly opposite the first touch surface 112. The touch detection module 20 is used to sense touch operations on the first touch surface 112. By setting a clearly defined first touch surface 112 on the outer surface of the sound-emitting component 10, and by setting the touch detection module 20 at the location of the first touch surface 112, the location of the first touch surface 112 can be accurately determined without blind touch, effectively avoiding accidental touches and improving the accuracy of blind touch operations.

[0073] This application provides a touch surface on the outer surface of the earphone 100, which has a clearly tactile boundary with the overall surface. This touch surface can be located on the outer surface of the sound output component 10. The touch surface is equipped with at least one sensor for recognizing touch control, swipe control, tap control, or press control to trigger the operating mode of the earphone 100. 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.

[0074] In one alternative implementation, please refer to Figure 1 The earphone 100 provided in this embodiment is a clip-on earphone. The earphone 100 also includes a power supply component 30 and a connector 40.

[0075] The power supply unit 30 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 30 has a built-in battery that provides power support for the earphone 100.

[0076] The connector 40 is also called a C-bridge / elastic arm. The connector 40 is made of flexible memory fiber or TPU material and is fixed to the auricle or ear bone by elastic clamping force, ensuring a stable fit while avoiding pressure. When worn, the connector 40 spans the longitudinal axis of the auricle, with the sound output component 10 located inside the auricle and the power supply component 30 located outside the auricle.

[0077] Please see Figure 1 The power supply component 30 and the sound output component 10 are spaced apart.

[0078] Please see Figure 1 The connector 40 is connected between the power supply component 30 and the sound output component 10. The connector 40 is arc-shaped. The shape of the connector 40 includes, but is not limited to, arc-shaped structures such as C-shaped, U-shaped, or teardrop-shaped structures.

[0079] The following example uses clip-on headphones. Of course, in other embodiments, the headphones 100 provided in this embodiment can be in-ear, semi-in-ear, ear-hook, over-ear, neckband, bone conduction, etc., and the design of clip-on headphones can also be referenced.

[0080] 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.

[0081] For the first alternative implementation, please refer to Figure 5 The first integral surface 111 includes a flat surface, and the first touch surface 112 includes a concave surface or a convex surface.

[0082] 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 first ridge line 115 with obvious tactile sensation, 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 touch detection element 21 to switch the working mode of the earphone 100.

[0083] For the second alternative implementation, please refer to... Figure 6 and Figure 7 The first overall surface 111 includes a curved surface, an arc surface, or a cylindrical surface, and the first touch surface 112 includes a plane, a concave surface, or a convex surface.

[0084] For example, the first integral surface 111 is a curved surface, an arc surface, or a cylindrical surface. The outer surface of the sound output component 10 is a three-dimensional curved surface, 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, or a convex surface that is convex relative to the first integral surface 111, so that the first touch surface 112 intersects with the first integral surface 111 and has a first edge 115 with obvious tactile feedback, 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 touch detection element 21 to switch the working mode of the earphone 100.

[0085] The structure of the sound-emitting housing 11 in this application will be illustrated below with reference to the accompanying drawings.

[0086] As mentioned above, please refer to Figure 2The sound-emitting housing 11 includes a front sound-emitting housing 113 and a rear sound-emitting housing 114 connected to each other. The front sound-emitting housing 113 and the rear sound-emitting housing 114 can be an integral structure or a separate structure.

[0087] Please see Figure 8 The front shell 113 for sound emission is disposed inside the ear canal. The rear shell 114 for sound emission is disposed outside the ear canal. The rear shell 114 has a first rear shell surface 1141 and at least one first touch surface 112. The first touch surface 112 is disposed on the rear shell 114, making it convenient and effortless for the operator to tilt their head and touch the vicinity of the ear canal to perform touch operation.

[0088] Please see Figure 8 The first touch surface 112 and the first rear shell 1141 have a ridge line, so that the operator can blindly identify the location of the first touch surface 112 in the sound-emitting rear shell 114.

[0089] The first integral surface 111 includes the first rear shell surface 1141 and the outer surface of the sound-emitting rear shell 114.

[0090] Taking the example of a separate structure for the front sound-emitting shell 113 and the rear sound-emitting shell 114, the front sound-emitting shell 113 is roughly cylindrical. The opening of the front sound-emitting shell 113 is opposite to and covers the opening of the rear sound-emitting shell 114.

[0091] Please see Figure 9 The sound-emitting rear shell 114 includes a cover portion 1142 and an extension portion 1145 that are interconnected. The cover portion 1142 and the extension portion 1145 are integrally formed structures and are also irregularly shaped structures.

[0092] The cover portion 1142 is generally cylindrical. The cover portion 1142 is connected to the front shell 113 for sound output.

[0093] For ease of explanation, the direction in which the cover 1142 points to the front shell 113 is defined as the first direction.

[0094] Please see Figure 9 The front shell 113 includes a front shell surface 1131 and a front shell peripheral surface 1132 surrounding the front shell surface 1131.

[0095] Please see Figure 9 The cover portion 1142 includes a first sub-touch surface 1143 and a first cover surface 1144.

[0096] Please see Figure 9The first sub-touch surface 1143 is disposed opposite to the front shell surface 1131 of the sound-emitting front shell 113. A first cover surface 1144 connects the first sub-touch surface 1143 and the peripheral side surface 1132 of the front shell of the sound-emitting front shell 113 in a first direction D1. The first cover surface 1144 also connects to the outer surface of the extension 1145 in a second direction D2. The second direction D2 is the direction in which the extension 1145 extends. The first direction D1 and the second direction D2 intersect. Optionally, the angle between the first direction D1 and the second direction D2 is less than or equal to 90°. Optionally, the angle between the first direction D1 and the second direction D2 is close to 90°, so that the extension 1145 can smoothly transition to the curved connector 40.

[0097] One end of the extension 1145 is connected to the side of the cover 1142. The other end of the extension 1145 (along the second direction D2) gradually moves away from the sound-emitting front shell 113.

[0098] For example, the front shell surface 1131 is circular. The peripheral side surface 1132 of the front shell is cylindrical. The first cover surface 1144 is a three-dimensional curved surface, close to a part of a sphere. The first sub-touch surface 1143 is, but is not limited to, a plane, a concave surface, or a convex surface. The dividing line between the first sub-touch surface 1143 and the first cover surface 1144 is the first ridge line 115.

[0099] The curvature of the first sub-touch surface 1143 is much smaller than that of the first cover surface 1144, so that the distance between the first sub-touch surface 1143 and the touch detection module 20 is more uniform. Furthermore, the distance between different touch detection elements 21 and the first sub-touch surface 1143 is more uniform, thereby improving the detection accuracy of different touch detection elements 21.

[0100] This application does not specifically limit the curvature of the first touch surface 112. Optionally, the curvature of the first touch surface 112 is as small as possible, so that the distance between different touch detection elements 21 and the first sub-touch surface 1143 is more uniform, thereby improving the detection accuracy of different touch detection elements 21.

[0101] For example, please see Figure 9 From the first side view of the sound output component 10, the orthographic projection of the first touch surface 112 is a slightly convex arc, which facilitates a smooth transition and connection with the curved connector 40, and also makes it easy to fit the fingertip. It also makes the distance between different touch detection elements 21 and the first sub-touch surface 1143 more uniform, thereby improving the detection accuracy of different touch detection elements 21.

[0102] From the second side view of the sound output component 10, please refer to Figure 10The highest line of the first touch surface 112 is a straight line, which makes the distance between different touch detection elements 21 and the first sub-touch surface 1143 more uniform and improves the detection accuracy of different touch detection elements 21.

[0103] Please see Figure 9 and Figure 11 The outer surface of the extension 1145 includes a second sub-touch surface 1147 and a first extension surface 1146. The second sub-touch surface 1147 is smoothly connected to the first sub-touch surface 1143. The first extension surface 1146 is a three-dimensional curved surface. One end of the first extension surface 1146 in the second direction D2 is connected to the first cover surface 1144. The other end of the first extension surface 1146 is connected to the connector 40. The first extension surface 1146 is generally a curved surface with a gradually changing cross-sectional area. The first extension surface 1146 and the first cover surface 1144 are smoothly connected. There is no dividing line between the first extension surface 1146 and the first cover surface 1144. There is no dividing line between the first cover surface 1144 and the peripheral side surface 1132 of the front shell. There is no dividing line between the second sub-touch surface 1147 and the first sub-touch surface 1143. The first extension surface 1146 and the peripheral side surface 1132 of the front shell are connected in an arc shape, with a clear dividing line.

[0104] Please see Figure 9 and Figure 11 The cross-sectional area of ​​the extension 1145 is smaller than that of the cover 1142. The cross-sectional area of ​​the extension 1145 gradually decreases from the cover 1142 to the extension 1145. The extension direction of the extension 1145 intersects the direction of the cover 1142 pointing towards the sound outlet front shell 113.

[0105] As a further example, the extension 1145 extends in an arc shape. The second sub-touch surface 1147 is the curved outer surface of the extension 1145, and the first extension surface 1146 is the curved inner surface of the extension 1145.

[0106] Please see Figure 11 The first touch surface 112 also includes the aforementioned first sub-touch surface 1143 and the aforementioned second sub-touch surface 1147 that are smoothly connected, so that the area of ​​the first touch surface 112 is relatively large and the length of the first touch surface 112 is relatively large in the direction of the cover portion 1142 pointing to the front shell 113, so as to form different touch areas or form a sliding touch area for sliding operation.

[0107] The first sub-touch surface 1143 is the surface of the cover portion 1142 facing away from the sound-emitting front shell 113. The second sub-touch surface 1147 is located on the extension portion 1145.

[0108] Of course, in other embodiments, the first sub-touch surface 1143 and the second sub-touch surface 1147 may not be smoothly connected, and there may be ridges between the first sub-touch surface 1143 and the second sub-touch surface 1147 to form different touch areas.

[0109] As mentioned above, please refer to Figure 12 The earphone 100 further includes a connector 40 and a power supply unit 30. The power supply unit 30 is disposed opposite to the sound output front shell 113. The connector 40 is curved. The connector 40 connects the sound output unit 10 and the power supply unit 30.

[0110] Please see Figure 13 The outer surface of the connector 40 includes a second integral surface 41 and a first connecting surface 42 that are connected to each other. The second integral surface 41 is located on the inner side of the bend of the connector 40. The first connecting surface 42 is located on the outer side of the bend of the connector 40. The first connecting surface 42 is smoothly connected to the second sub-touch surface 1147. The second integral surface 41 is smoothly connected to the front shell surface 1131. Further, the second integral surface 41 is smoothly connected to the first extension surface 1146.

[0111] Thus, the extension 1145 not only provides a second sub-touch surface 1147, increasing the area and length of the first touch surface 112, but also facilitates the formation of a long, narrow sliding touch area for easy sliding operation. The increased length of the sliding touch area allows for an increase in the number of touch detection elements 21, thereby improving the accuracy of sliding touch detection and preventing accidental touches.

[0112] Further optional information can be found in [link to relevant documentation]. Figure 13 The ridge line between the front shell surface 1131 and the first touch surface 112 connects to the ridge line between the second integral surface 41 and the first connecting surface 42. The trajectory of the ridge line between the front shell surface 1131 and the first touch surface 112 resembles a teardrop shape.

[0113] Optionally, at least a portion of the touch detection module 20 is disposed on or directly opposite the first connecting surface 42. The touch detection module 20 is also used to sense touch operations on the first connecting surface 42. This further increases the area and length of the touch sensing region, facilitating the formation of a long, narrow sliding touch area for easier sliding operation. Increasing the length of the sliding touch area (e.g., a sliding length greater than 10 mm) allows for an increase in the number of touch detection elements 21, thereby improving the accuracy of sliding touch detection and preventing accidental touches.

[0114] Optionally, the touch detection module 20 is positioned directly opposite the first touch surface 112.

[0115] Please see Figure 14 The sound-emitting housing 11 includes a first sub-housing portion 117 ( Figure 14 (the thickened solid line in the middle) and the second sub-shell part 118 ( Figure 14 (The dashed part in the text).

[0116] The first touch surface 112 is disposed on the first sub-shell portion 117. The first integral surface 111 is disposed on the second sub-shell portion 118. The first sub-shell portion 117 is the shell portion of the sound-emitting shell 11 on which the first touch surface 112 is disposed. The second sub-shell portion 118 is the shell portion of the sound-emitting shell 11 on which the first integral surface 111 is disposed.

[0117] The first sub-shell portion 117 and the second sub-shell portion 118 can be integrally formed or separately formed.

[0118] When the fingertip is placed on the first touch surface 112, the distance between the touch detection module 20 and the fingertip is the first sub-shell portion 117. In this embodiment, by setting the thickness of the first sub-shell portion 117 to be less than the thickness of the second sub-shell portion 118, the distance between the touch detection module 20 and the fingertip is reduced, improving touch sensitivity and response speed. For example, capacitive touch sensors operate by detecting changes in capacitance between the finger and electrodes. Shortening the distance increases the amplitude of capacitance changes, making it easier for the sensor to identify weak touch signals, especially effective for edge touch or low-pressure operation scenarios. Furthermore, reducing the distance between the touch detection module 20 and the fingertip optimizes anti-mistouch performance. Close contact enhances the sensor's accuracy in determining the effective touch area; it also improves the accuracy of multi-touch positioning, which relies on the sensor to accurately locate multiple touch points. Shortening the distance reduces capacitive interference between fingers and increases the minimum recognition distance.

[0119] Of course, in other embodiments, the thickness of the first sub-shell portion 117 is equal to the thickness of the second sub-shell portion 118, reducing the processing difficulty of the first sub-shell portion 117 being equal to the second sub-shell portion 118.

[0120] Further optional information can be found in [link to relevant documentation]. Figure 15 The thickness of the first sub-shell portion 117 is less than or equal to the first preset thickness, which makes the detection distance between the touch detection module 20 and the fingertip smaller, thereby improving touch sensitivity and response speed, and thus improving detection accuracy.

[0121] This application does not specify the first preset thickness, which is 3mm.

[0122] Optionally, the outer surface of the first sub-shell portion 117 has a different tactile feel than the outer surface of the second sub-shell portion 118, so that the operator can identify the location of the first touch surface 112 on the sound output shell 11 when blindly touching it, and then touch control the earphone 100.

[0123] The following provides specific examples illustrating the difference in tactile feel between the outer surface of the first sub-shell portion 117 and the outer surface of the second sub-shell portion 118.

[0124] For the first alternative implementation, please refer to Figure 14 The sound-emitting housing 11 includes a first sub-housing portion 117 and a second sub-housing portion 118.

[0125] The first touch surface 112 is disposed on the first sub-shell portion 117. The first integral surface 111 is disposed on the second sub-shell portion 118. The first sub-shell portion 117 and the second sub-shell portion 118 are made of different materials.

[0126] For example, one of the first sub-shell portion 117 and the second sub-shell portion 118 is a hard plastic shell, and the other is a soft plastic shell. The surface textures of the first sub-shell portion 117 and the second sub-shell portion 118 are different, which makes it easier for users to distinguish the first touch surface 112 of the first sub-shell portion 117 based on the different textures even when touching blindly, thereby improving touch recognition efficiency.

[0127] The materials of the hard plastic shell include, but are not limited to, acrylonitrile butadiene styrene (ABS) or polycarbonate (PC).

[0128] The materials of the soft shell include, but are not limited to, thermoplastic elastomers, thermoplastic polyurethanes, silicone, rubber, or leather.

[0129] Of course, the materials of the first sub-shell portion 117 and the second sub-shell portion 118 include, but are not limited to, any two of the following: metal, plastic, thermoplastic elastomer, thermoplastic polyurethane, silicone, rubber, leather, ceramic, glass, etc.

[0130] For the second alternative implementation, please refer to... Figure 14 The sound-emitting housing 11 includes a first sub-housing portion 117 and a second sub-housing portion 118. The first touch surface 112 is disposed on the first sub-housing portion 117. The first integral surface 111 is disposed on the second sub-housing portion 118. The roughness of the first sub-housing portion 117 and the second sub-housing portion 118 is different.

[0131] For example, the difference between the roughness of the first touch surface 112 of the first sub-shell portion 117 and the roughness of the first integral surface 111 of the second sub-shell portion 118 is greater than or equal to the first roughness, so that the operator can clearly distinguish the first touch surface 112 and the first integral surface 111 by touch. This makes it easier for the user to distinguish the first touch surface 112 of the first sub-shell portion 117 by different touches even when touching blindly, thus improving touch recognition efficiency.

[0132] This application does not specify a particular first roughness. Optionally, the first roughness may be greater than or equal to 0.4 μm.

[0133] The first touch surface 112 and the first integral surface 111 include, but are not limited to, any two of the following: matte, glossy, textured, semi-gloss, frosted, brushed, swirl, sandblasted, etched, orange peel texture, leather texture, anti-slip texture, anti-fingerprint, matte finish, conductive texture, anodized dyeing, and textured.

[0134] For example, the first touch surface 112 is matte and the first overall surface 111 is glossy, so that users can easily distinguish the first touch surface 112 of the first sub-shell 117 based on different tactile sensations even when touching blindly, thereby improving touch recognition efficiency.

[0135] This embodiment distinguishes the touch area by setting the roughness of the first touch surface 112 and the first integral surface 111 of the sound output housing 11 to be different.

[0136] In this embodiment, the first sub-shell portion 117 and the second sub-shell portion 118 may be made of the same or different materials.

[0137] The touch detection module 20 provided in this application will be illustrated below with reference to the accompanying drawings.

[0138] Optional, please refer to Figure 16 The touch detection module 20 includes a first detection element 22 and a second detection element 23 disposed opposite to the first touch surface 112.

[0139] The difference between the distance between the first detection element 22 and the first touch surface 112 and the distance between the first detection element 22 and the first touch surface 112 is less than or equal to a first preset difference. This application does not specifically limit the first preset difference. For example, the first preset difference is 0.05 mm. In other embodiments, the first preset difference is 0.04 mm, 0.03 mm, 0.02 mm, or 0.01 mm. Further optionally, the distance between the first detection element 22 and the first touch surface 112 is equal to the distance between the first detection element 22 and the first touch surface 112. That is, the distance between different detection elements and the first touch surface 112 is uniform.

[0140] This embodiment improves signal consistency, optimizes sliding trajectory accuracy, reduces sliding delay, enhances sliding detection accuracy, and prevents missed detections by designing different detection elements with uniform distances between them and the first touch surface 112.

[0141] For example, when the detection element is a capacitive sensor, by setting a uniform distance between the detection element and the first touch surface 112, the electric field distribution formed by the electrode and the finger is ensured to be stable, so that the capacitance change (ΔC) of the capacitive sensor is only related to the sliding distance and is not affected by height fluctuations, simplifying the algorithm complexity and improving the sliding detection accuracy.

[0142] In this embodiment, the actions detected by the touch detection module 20 include, but are not limited to, any at least one of sliding, tapping, pressing, touching, hovering, and gestures.

[0143] In other words, the touch detection module 20 includes at least one of a sliding detection unit, a tapping detection unit, a pressing detection unit, and a touch detection unit.

[0144] For example, the touch detection module 20 includes a slide detection unit. Optionally, the slide detection unit is used to identify continuous movement trajectories. Optionally, the slide detection unit includes, but is not limited to, a capacitor array (self / mutual capacitance) and / or an optical sensor.

[0145] For example, the touch detection module 20 includes a tap detection unit. Optionally, the tap detection unit is used to detect discrete click actions, and the tap detection unit may include, but is not limited to, a piezoelectric film (PVDF).

[0146] For example, the touch detection module 20 includes a pressure detection unit. Optionally, the pressure detection unit is used to sense pressure levels (3D Touch). Optionally, the pressure detection unit includes, but is not limited to, strain gauges (metal / semiconductor) and / or capacitive pressure sensing layers.

[0147] For example, the touch detection module 20 includes a touch detection unit. Optionally, the touch detection unit is used to detect the presence of contact. Optionally, the touch detection unit includes, but is not limited to, surface-mount capacitance (ITO) and / or projected capacitance (P-CAP).

[0148] For example, the touch detection module 20 includes a hover detection unit. Optionally, the hover detection unit is used to recognize non-contact gestures (Hover). Optionally, the hover detection unit includes, but is not limited to, near-field imaging (NFI) sensors and / or millimeter-wave radar.

[0149] For example, the touch detection module 20 includes a gesture detection unit. Optionally, the gesture detection unit is used for spatial gesture interaction (such as air gestures) and recognizing complex operations such as zooming / rotating. Optionally, the gesture detection unit may include, but is not limited to, any one of a matrix capacitive array, an optical ToF sensor, a millimeter-wave radar, a stereo vision camera, etc.

[0150] For example, the touch detection module 20 includes a biometric detection unit. Optionally, the biometric detection unit is used for fingerprint / vein recognition.

[0151] Optionally, the biometric detection unit may include, but is not limited to, an ultrasonic fingerprint sensor.

[0152] For example, the touch detection module 20 includes an ambient sensing unit. Optionally, the ambient sensing unit is used to distinguish between genuine touches and accidental touches. Optionally, the ambient sensing unit may include, but is not limited to, radio frequency impedance monitoring.

[0153] As mentioned above, please refer to Figure 2 The sound-emitting housing 11 includes a front sound-emitting housing 113 and a rear sound-emitting housing 114 connected to each other. The front sound-emitting housing 113 is disposed inside the ear canal. The rear sound-emitting housing 114 is disposed outside the ear canal. The first touch surface 112 is part of the outer surface of the rear sound-emitting housing 114, so that the user can touch the first touch surface 112 when raising their hand to the vicinity of the ear canal.

[0154] As mentioned above, please refer to Figure 2 The earphone 100 further includes a connector 40 that connects to the sound output component 10. The first touch surface 112 is located in the area of ​​the sound output rear shell 114 adjacent to or connected to the connector 40.

[0155] When the earphone 100 is worn in the ear, the area of ​​the sound-emitting shell 114 adjacent to or connected to the connector 40 is the outward-facing area, which is also the area that the user can easily touch by blindly reaching near the ear canal. In this embodiment, by setting the touch surface to be located near the connector 40 on the sound-emitting component 10, the user can easily touch the first touch surface 112 by blindly reaching near the ear canal to control the earphone 100.

[0156] Optionally, the first touch surface 112 is smoothly connected to at least a portion of the outer surface of the connector 40.

[0157] Specifically, the first touch surface 112 is smoothly connected to the first connecting surface 42 on the aforementioned connector 40 to ensure the smoothness of the overall outer surface of the earphone 100. At the same time, it also allows the first connecting surface 42 on the subsequent connector 40 to also serve as a touch surface, which helps to increase the area and length of the touch surface, thereby increasing the number of touch detection elements and improving the accuracy of slide detection.

[0158] Furthermore, the first integral surface 111 of the sound output component 10 and the second integral surface 41 of the connector 40 are also smoothly connected. Optionally, the ridge line between the first integral surface 111 and the first touch surface 112 connects to the ridge line between the second integral surface 41 and the first connecting surface 42. The trajectory of the ridge line between the first integral surface 111 and the first touch surface 112 resembles a teardrop shape.

[0159] Alternatively, the housing of the sound-emitting component 10 is a hard housing, while the housing of the connector 40 is a soft rubber housing.

[0160] Although the outer surfaces of the speaker 10 and the connector 40 are smoothly connected in this embodiment, the outer shell of the speaker 10 is made of hard material and the outer shell of the connector 40 is made of soft plastic to distinguish the touch area on the speaker 10, avoid touching the area where the touch detection module 20 is not set, and improve the touch detection efficiency.

[0161] As mentioned above, please refer to Figure 17 The outer surface of the connector 40 also includes a second touch surface 43. The second touch surface 43 is smoothly connected to the first touch surface 112. At least a portion of the touch detection module 20 is disposed on or directly opposite the second touch surface 43.

[0162] This embodiment increases the touch recognition area and improves the sliding recognition accuracy by also using a portion of the outer surface of the connector 40 as a touch surface.

[0163] As mentioned above, please refer to Figure 17 The outer surface of the connector 40 also includes a second integral surface 41. The second integral surface 41 intersects with the second touch surface 43.

[0164] The second integral surface 41 is the main surface of the connector 40. The second touch surface 43 is a partial surface on the connector 40. The number of second touch surfaces 43 can be one or more.

[0165] The second touch surface 43 and the second integral surface 41 have a clearly tactile boundary line (edge) to facilitate blind touch identification of the second touch surface 43. For ease of explanation, this application defines the boundary line between the second touch surface 43 and the second integral surface 41 as the second edge line. This application does not make specific limitations on the trajectory of the second edge line, etc.

[0166] This application does not specify the size or shape of the second touch surface 43. Optionally, the second touch surface 43 may be rectangular, circular, elliptical, irregular, or the shape of a fingertip, etc.

[0167] Please see Figure 17The second touch surface 43 and the second integral surface 41 are interconnected as one unit. For example, the second touch surface 43 and the second integral surface 41 are made of the same material. The second touch surface 43 and the second integral surface 41 are intersecting surfaces formed from the same substrate. As another example, the material of the second touch surface 43 is different from that of the second integral surface 41, and the second touch surface 43 and the second integral surface 41 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 43 to be different from that of the second integral surface 41, it is easier for the operator to identify the second touch surface 43 by blind touch.

[0168] The second touch surface 43 is not smoothly connected to the second integral surface 41. The operator can easily find the location of the second touch surface 43 by blind touch on the outer surface of the connector 40, thereby avoiding accidental touches and improving the accuracy of touch / swipe / pressure-sensitive position recognition.

[0169] Optionally, the first touch surface 112 and the second touch surface 43 can form a complete touch surface. The touch detection module 20 is aligned with this complete touch surface. The first ridge 115 is connected to the second ridge.

[0170] The following example illustrates the structure of the touch detection module 20.

[0171] Please see Figure 18 The earphone 100 also includes a flexible circuit board 50. The touch detection module 20 includes at least one first detection element 22. The first detection element 22 is also the aforementioned touch detection element 21. This application does not specify the number of first detection elements 22.

[0172] Please see Figure 18 The flexible circuit board 50 includes a first functional area 51. A first detection element 22 is disposed in the first functional area 51 of the flexible circuit board 50. The first detection element 22 is electrically connected to a control module, power supply, etc., through traces on the flexible circuit board 50. The control module may be disposed on the flexible circuit board 50 or outside the flexible circuit board 50.

[0173] The first functional area 51 of the flexible circuit board 50 is located inside the sound output housing 11 and is directly opposite to the first touch surface 112. The first detection element 22 is located on the first functional area 51 of the flexible circuit board 50 and is directly opposite to the first touch surface 112 to detect touch operations.

[0174] Optional, please refer to Figure 18 The connector 40 also includes a through hole 44. The through hole 44 is provided through both ends of the connector 40 along the extending direction of the connector 40.

[0175] Please see Figure 18The flexible circuit board 50 is inserted through the through hole 44 of the connector 40. One end of the flexible circuit board 50 is electrically connected to the electroacoustic device 72 in the sound output component 10, and the other end of the flexible circuit board 50 is electrically connected to the power supply. The flexible circuit board 50 is also used to realize the electrical connection between the sound output component 10 and the power supply component 30.

[0176] Because the flexible circuit board 50 has a relatively large bearing area, it can face the first touch surface 112 and support a large number of touch detection modules 20. In addition, the flexible circuit board 50 is thin and can be attached to the inner surface of the sound output component 10, occupying little space.

[0177] Among them, the connector 40 has a certain elastic deformation capability, and the connector 40 can return to its initial state after deformation.

[0178] Optionally, the connector 40 may be in a straight line, an arc, a bend, a curve, or a spiral shape in its initial state. In this embodiment, the connector 40 is generally in a C-shaped bend as an example.

[0179] Optionally, the flexible circuit board 50 can deform in the through hole 44 as the connector 40 bends, so as to ensure that the connector 40 can bend while ensuring the electrical connection between the sound output component 10 and the power supply component 30 is stable.

[0180] In this embodiment, the width direction of the flexible circuit board 50 is consistent with the width direction of the connector 40, the length direction of the flexible circuit board 50 is consistent with the length direction of the connector 40, and the thickness direction of the flexible circuit board 50 is consistent with the thickness direction of the flexible circuit board 50.

[0181] The flexible circuit board 50 can be movably inserted into the through hole 44 to prevent the traces on the flexible circuit board 50 from being pulled and damaged during the bending of the connector 40.

[0182] Further optional information can be found in [link to relevant documentation]. Figure 19 The headphones 100 also include a support 60.

[0183] The support member 60 has a certain rigidity and a certain elastic deformation capacity. The support member 60 can return to its initial state after deformation, so that the connecting member 40 can maintain its initial state when not subjected to external force, deform after being subjected to external force, and return to its initial state after the external force is removed.

[0184] The support member 60 is disposed opposite to the flexible circuit board 50. The support member 60 can be disposed on the inner or outer side of the bend of the flexible circuit board 50. The support member 60 can maintain its shape and has good deformation capacity and deformation recovery capacity. The support member 60 has relatively high rigidity to protect the flexible circuit board 50 during bending and prevent the flexible circuit board 50 from being damaged by external forces.

[0185] For example, the material of the support member 60 may include, but is not limited to, shape memory polymers, shape memory alloys, elastic metal alloys, or stainless steel, or the material of the support member 60 may include, but is not limited to, thermoplastic elastomers, or other polymeric materials. Support members 60 made of the above materials are capable of returning to their initial shape after elastic deformation.

[0186] Shape memory alloys include, but are not limited to, at least one of nickel-titanium based alloys, copper-based alloys, or iron-based alloys.

[0187] This application does not specify the shape of the support member 60.

[0188] The shape of the support member 60 can be any one of the following: filament, rod, sheet, mesh, rope, etc.

[0189] Optional, please refer to Figures 20-22 The touch detection module 20 further includes at least one second detection element 23. The second detection element 23 is disposed in the second functional area 52 of the flexible circuit board 50. The second functional area 52 of the flexible circuit board 50 is located within the connector 40 and faces the second touch surface 43. The second detection element 23 cooperates with the first detection element 22 for detection or detects independently.

[0190] For example, the first touch surface 112 and the second touch surface 43 can be independent touch surfaces, and the first touch surface 112 and the second touch surface 43 can be non-smoothly connected. The touch operation corresponding to the first touch surface 112 may be the same as or different from the touch operation corresponding to the second touch surface 43.

[0191] For another example, the first touch surface 112 and the second touch surface 43 can form a complete touch surface, and the first touch surface 112 and the second touch surface 43 can be smoothly connected, and a relatively long sliding touch surface can be provided. For example, the first touch surface 112 and the second touch surface 43 form a touch surface with a length greater than 10mm (e.g., 10mm to 20cm), which is conducive to sliding operation and reduces the probability of accidental touch.

[0192] This application does not specify the length of the second touch surface 43.

[0193] Optionally, the touch detection module 20 includes a plurality of touch detection elements 21.

[0194] The headset 100 also includes a control module. The control module is electrically connected to a plurality of the touch detection elements 21. The control module is used to control the headset 100 to enter a first operating mode when at least two of the touch detection elements 21 detect a signal. The first operating mode includes 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.

[0195] For example, please see Figure 23 The touch detection module 20 includes a first detection element 22 and a second detection element 23 spaced apart. The earphone 100 also includes a control module electrically connected to the first detection element 22 and the second detection element 23. The control module is further configured to control the earphone 100 to enter a first operating mode when both the first detection element 22 and the second detection element 23 detect a signal. The first operating mode includes any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio and video playback.

[0196] For another example, please refer to Figure 24 The touch detection module 20 includes a first detection element 22, a second detection element 23, and a third detection element 24 arranged at intervals. The earphone 100 also includes a control module. The control module is electrically connected to the first detection element 22, the second detection element 23, and the third detection element 24.

[0197] The first detection element 22, the second detection element 23, and the third detection element 24 are arranged sequentially at intervals.

[0198] The control module is further configured to control the earphone 100 to enter a first working mode when both the first detection element 22 and the second detection element 23 detect a signal, to prevent the earphone 100 from accidentally entering the first working mode due to accidental activation of a single detection element. The first working mode includes any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, switch between audio and video playback, etc.; or...

[0199] The control module is further configured to control the earphone 100 to enter a first working mode when both the second detection element 23 and the third detection element 24 detect a signal, to prevent the earphone 100 from accidentally entering the first working mode due to accidental activation of a single detection element. The first working mode includes any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, switch between audio and video playback, etc.; or...

[0200] The control module is further configured to control the earphone 100 to enter a first working mode when all three detection elements—the first detection element 22, the second detection element 23, and the third detection element 24—detect a signal. This prevents accidental activation of a single detection element, thus improving the accuracy of accidental activation prevention. The first working mode includes any one of the following: play, pause, exit playback, answer a call, hang up a call, increase volume, decrease volume, or switch between audio and video playback.

[0201] The touch detection module 20 includes a plurality of touch detection elements 21. At least two of the touch detection elements 21 are arranged in the direction from the sound output element 10 to the connector 40.

[0202] Specifically, the first detection element 22, the second detection element 23, and the third detection element 24 can form a span with a length greater than or equal to 10 mm. Further optionally, the first detection element 22, the second detection element 23, and the third detection element 24 are arranged along the direction from the sound output element 10 to the connector 40, so as to form a touch detection module 20 capable of detecting sliding operations and having a certain length of sliding detection capability, so that when the operator slides along the connector 40 to the sound output element 10, the earphone 100 is triggered to enter the first working mode.

[0203] This application does not limit the sliding sequence. Optionally, the sliding action can be along the direction from the sound output element 10 to the connector 40 to reduce the volume. Alternatively, the sliding action can be along the direction from the connector 40 to the sound output element 10 to increase the volume.

[0204] In other embodiments, the plurality of touch detection elements 21 may also be arranged in a lateral direction or in a cross shape.

[0205] The first touch surface 112 in this application may have one or more touch areas. The touch operation corresponding to each touch area may be the same or different. Different touch areas perform touch operations to control the headset 100 to enter different working modes. The working modes include 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.

[0206] Please see Figure 12 The earphone 100 also includes an adhesive member 71. The adhesive member 71 is bonded to the inner surface of the touch detection module 20 and the first housing portion, so that the touch detection module 20 is disposed close to the first housing portion. The touch detection module 20 is disposed opposite to the first touch surface 112.

[0207] In this embodiment, the adhesive 71 can be, but is not limited to, double-sided adhesive.

[0208] The length L of the first touch surface 112 of the sound output component 10 in the extending direction satisfies: 6mm ≤ L ≤ 20mm. If the size of the first touch surface 112 in the extending direction is too small, it indicates that the touch detection module 20 occupies a small size, which is not conducive to operating the touch detection module 20 on the first touch surface 112 (such as sliding operation); if the size of the first touch surface 112 in the extending direction is too large, it indicates that the touch detection module 20 occupies a large size, which is not conducive to setting other devices or modules in the sound output component 10 of the earphone 100.

[0209] The sound output component 10 provided in this application embodiment has a first touch surface 112 whose length L in the extension direction satisfies: 6mm≤L≤20mm. On the one hand, this is beneficial for operating the touch detection module 20 on the first touch surface 112, for example, making the sliding operation more comfortable; on the other hand, the size occupied by the touch detection module 20 is moderate, leaving relatively sufficient space for setting other devices or modules in the sound output component 10.

[0210] Furthermore, the length L of the first touch surface 112 in the extending direction satisfies: 10mm≤L≤15mm, which further accommodates the operation of the touch detection module 20 on the first touch surface 112; and also accommodates the setting of other devices or modules in the sound output component 10.

[0211] In one implementation, please refer to Figure 24 If the touch detection module 20 detects a touch action along a third direction D3, it triggers a first function. If the touch detection module 20 detects a touch action along a fourth direction D4, it triggers a second function, wherein the fourth direction D4 is opposite to the third direction D3, and the first function is opposite to the second function.

[0212] Touch operations along the third direction D3 can be called sliding operations or sliding touch along the third direction D3, and size operations along the fourth direction D4 can also be called sliding operations or sliding touch along the fourth direction D4.

[0213] In this embodiment, if the touch detection module 20 detects a touch action along a third direction D3, the first function is triggered; if the touch detection module 20 detects a touch action along a fourth direction D4, the second function is triggered; the fourth direction D4 is opposite to the third direction D3, and the second function is opposite to the first function; thus, it can be seen that the sound output device 10 provided in this embodiment is easy to control using the touch detection module 20, and the control method is relatively simple.

[0214] In one implementation, please refer to Figure 24The touch detection module 20 includes a plurality of touch detection elements 21 (such as sensing capacitors) arranged along a third direction D3. The plurality of touch detection elements 21 refers to two or more touch detection elements 21. For example, in one embodiment, the touch detection module 20 includes two touch detection elements 21 arranged along a third direction D3, the two touch detection elements 21 being spaced apart. In another embodiment, the touch detection module 20 includes three touch detection elements 21 arranged along a third direction D3, the three touch detection elements 21 being spaced apart.

[0215] In one embodiment, the touch detection module 20 is integrated into the flexible circuit board 50. The flexible circuit board 50 includes a circuit board body. Specifically, the circuit board body includes a conductive layer, and the touch detection module 20 is located on the conductive layer. The touch detection module 20 includes a plurality of touch detection elements 21, which are located on the conductive layer. During the fabrication of the flexible circuit board 50, the plurality of touch detection elements 21 can be fabricated in the conductive layer of the circuit board body. Furthermore, during the fabrication of the flexible circuit board 50, corresponding connecting wires can also be fabricated in the conductive layer of the circuit board body.

[0216] In this embodiment, the third direction D3 is the direction toward the sound output component 10, and the first function is either decreasing the volume or increasing the volume. Correspondingly, the fourth direction D4 is the direction away from the sound output component 10, and the second function is either decreasing the volume or increasing the volume.

[0217] Since the third direction D3 is towards the sound output component 10, and the fourth direction D4 is away from the sound output component 10, when the user operates the area of ​​the sound output component 10 corresponding to the touch detection module 20, the size of the extension direction of the sound output component 10 can be utilized. There is enough space in the sound output component 10 to arrange the touch detection module 20, and the width of the sound output component 10 can be avoided.

[0218] In this embodiment, the first function is either decreasing the volume or increasing the volume; correspondingly, the second function is either decreasing the volume or increasing the volume. Thus, the volume can be controlled by operating the touch operation area of ​​the connecting shell 131 corresponding to the touch detection module 20 along the third direction D3 or along the fourth direction D4, and the control method is relatively simple.

[0219] Understandably, in other embodiments, the third direction D3 is the width direction of the sound output member 10, and correspondingly, the fourth direction D4 is the direction opposite to the third direction D3 in the width direction of the sound output member 10. This application does not limit the third direction D3 and the fourth direction D4, as long as the third direction D3 and the fourth direction D4 are opposite.

[0220] Understandably, in this embodiment, the first function is either decreasing the volume or increasing the volume; the second function is either decreasing the volume or increasing the volume, which is just one example. In the sound output device 10 provided in one embodiment of this application, decreasing the volume means decreasing the volume of the speaker, and correspondingly, increasing the volume means increasing the volume of the speaker. Understandably, in other embodiments, if the electroacoustic device 72 of the headphones 100 plays music, the first function is either playing the next song or playing the previous song, and correspondingly, the second function is either playing the next song or playing the previous song. Understandably, in yet another embodiment, if the electroacoustic device 72 of the headphones 100 plays audio (including music or voice, etc.), the first function may also be either playing at double speed or playing at slow speed; the second function may be either playing at double speed or playing at slow speed. The headphones 100 provided in this application embodiment does not limit the first function and the second function.

[0221] In another embodiment, the first function includes connecting to Bluetooth and disconnecting Bluetooth, and the second function includes connecting to Bluetooth or disconnecting Bluetooth.

[0222] In other embodiments, the first function includes switching device connections and not switching device connections, and the second function includes switching device connections and not switching device connections.

[0223] Therefore, the sound output device 10 provided in this application embodiment has a first function triggered by the touch detection module 20 when a touch operation along the third direction D3 is detected, and a second function triggered by the touch operation along the fourth direction D4 is detected. The second function is the opposite of the first function, which makes it easier to control the first function and the second function.

[0224] In one embodiment, if the touch detection module 20 detects a touch operation exceeding a preset duration and is a first duration, a preset mode is activated. If the touch detection module 20 detects a touch operation exceeding a preset duration and is a second duration, the preset mode is deactivated.

[0225] If the touch detection module 20 detects a touch operation that exceeds a preset duration and is a first duration, the preset mode is activated to reduce or even avoid accidental touches and improve the accuracy of activating the preset mode.

[0226] If the touch detection module 20 detects a touch operation that exceeds a preset time and is a second duration, it closes the preset mode, thereby reducing or even avoiding accidental touches and closing the preset mode, thus improving the accuracy of closing the preset mode.

[0227] Touch operations exceeding a preset duration can also be termed long-press touch. In one embodiment, the first duration and the second duration are equal. In another embodiment, the first duration and the second duration are not equal.

[0228] The preset mode may include, but is not limited to, a noise reduction mode for the speaker. For example, if the preset mode of the headphone 100 of the sound output device 10 is off, and the touch detection module 20 detects that the touch operation exceeds a preset duration and is a first duration, the preset mode of the electroacoustic device 72 is turned on. If the preset mode of the headphone 100 is on, and the detection mode detects that the touch operation exceeds a preset duration and is a second duration, the preset mode of the electroacoustic device 72 is turned off.

[0229] The sound output device 10 provided in this embodiment can enable or disable a preset mode based on the duration of the touch operation detected by the touch detection module 20, thereby making it relatively easy to enable or disable the preset mode.

[0230] In any of the aforementioned optional embodiments, the earphone 100 further includes the aforementioned control module and feedback device.

[0231] The control module is electrically connected to the touch detection element 21 and the feedback device. The control module is also used to control the feedback device to generate a corresponding feedback signal according to the signal characteristics of the touch detection element 21, so that the operator knows that the control module has recognized the operator's touch press operation, and avoids the operator repeatedly pressing the button because he does not know whether the control module has recognized the press operation.

[0232] Feedback devices include sound-emitting devices and / or vibration devices.

[0233] For example, the feedback device includes a sound-emitting device, such as an acoustic module. After receiving a pressing pressure recognized by the touch detection element 21, the control module controls the acoustic module to generate a feedback sound signal.

[0234] For another example, the feedback device includes a vibration device, such as a vibration motor. After receiving the pressing pressure recognized by the touch detection element 21, the control module controls the vibration motor to generate a feedback vibration signal.

[0235] For example, the feedback device 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 a pressing pressure recognized by the touch detection element 21, the control module controls the acoustic module to generate a feedback sound signal and / or controls the vibration motor to generate a feedback vibration signal.

[0236] Depending on the pressure applied by the touch detection element 21, the control module can generate different feedback signals. In other words, the feedback signals can correspond one-to-one with the pressure applied by the touch detection element 21.

[0237] The above description is from the perspective of the overall headphone 100. The following description focuses on the outer surface morphology of the sound output component 10 and the outer surface morphology of the connector 40.

[0238] Please see Figure 2 This application also provides an earphone 100. The earphone 100 includes a sound output component 10 and a touch detection module 20.

[0239] Please see Figure 9 The sound-emitting component 10 includes a front sound-emitting shell 113 and a rear sound-emitting shell 114 connected to each other. The front sound-emitting shell 113 is disposed inside the ear canal. The rear sound-emitting shell 114 is disposed outside the ear canal. The rear sound-emitting shell 114 has a front shell surface 1131 and at least one first touch surface 112. A ridge line is formed between the first touch surface 112 and the front shell surface 1131.

[0240] The touch detection module 20 is disposed within the sound output rear shell 114. At least a portion of the touch detection module 20 is disposed on or directly opposite the first touch surface 112. The touch detection module 20 is used to sense touch operations on the first touch surface 112.

[0241] Please see Figure 16 The touch detection module 20 includes at least one first detection element 22. The first detection element 22 is also the aforementioned touch detection element 21. This application does not specify the number of first detection elements 22.

[0242] Please see Figure 18 The first detection element 22 is disposed in the first functional area 51 of the flexible circuit board 50. The first detection element 22 is electrically connected to the control module, power supply, etc. through the wiring on the flexible circuit board 50. The control module may be disposed on the flexible circuit board 50 or outside the flexible circuit board 50.

[0243] Please see Figure 18 The first functional area 51 of the flexible circuit board 50 is located inside the sound-emitting housing 11 and is directly opposite to the first touch surface 112. The first detection element 22 is located on the first functional area 51 of the flexible circuit board 50 and is directly opposite to the first touch surface 112 to detect touch operations.

[0244] The sound output element 10 in this embodiment can be referred to the relevant description of the sound output element 10 in the aforementioned embodiment one.

[0245] The touch detection module 20 in this embodiment can be referred to the relevant description of the touch detection module 20 in the aforementioned embodiment 1.

[0246] This application provides an earphone 100, which includes a sound-emitting component 10 and a touch detection module 20. The sound-emitting component 10 includes a front sound-emitting shell 113 and a rear sound-emitting shell 114 connected to each other. The front sound-emitting shell 113 is disposed inside the ear canal, and the rear sound-emitting shell 114 is disposed outside the ear canal. The rear sound-emitting shell 114 has a front shell surface 1131 and at least one first touch surface 112, and a ridge line is formed between the first touch surface 112 and the front shell surface 1131. The touch detection module 20 is disposed on the rear sound-emitting shell 113. Within 4, at least a portion of the touch detection module 20 is disposed on or directly opposite the first touch surface 112. The touch detection module 20 is used to sense touch operations on the first touch surface 112. By setting a clearly demarcated first touch surface 112 on the outer surface of the speaker housing 114, and by setting the touch detection module 20 at the location of the first touch surface 112, the location of the first touch surface 112 can be accurately determined to avoid blind touches, effectively avoiding accidental touches and improving the accuracy of blind touch operations.

[0247] The structure of the sound-emitting housing 11 in this application will be illustrated below with reference to the accompanying drawings.

[0248] Please see Figure 2 The sound-emitting housing 11 includes a front sound-emitting housing 113 and a rear sound-emitting housing 114 connected to each other. The front sound-emitting housing 113 and the rear sound-emitting housing 114 can be an integral structure or a separate structure.

[0249] Please see Figure 9 The front shell 113 for sound emission is disposed inside the ear canal. The rear shell 114 for sound emission is disposed outside the ear canal. The rear shell 114 has a front shell surface 1131 and at least one first touch surface 112. The first touch surface 112 is disposed on the rear shell 114, making it convenient and effortless for the operator to tilt their head and touch the vicinity of the ear canal to perform touch operation.

[0250] The first touch surface 112 has a ridge between it and the front shell surface 1131, so that the operator can blindly identify the location of the first touch surface 112 in the sound-emitting rear shell 114.

[0251] The first integral surface 111 includes the outer surface of the front shell surface 1131 and the outer surface of the sound-emitting rear shell 114.

[0252] Taking the example of a separate structure for the front sound-emitting shell 113 and the rear sound-emitting shell 114, the front sound-emitting shell 113 is roughly cylindrical. The opening of the front sound-emitting shell 113 is opposite to and covers the opening of the rear sound-emitting shell 114.

[0253] Please see Figure 9 The sound-emitting rear shell 114 includes a cover portion 1142 and an extension portion 1145 that are interconnected. The cover portion 1142 and the extension portion 1145 are integrally formed structures and are also irregularly shaped structures.

[0254] The cover portion 1142 is generally cylindrical. The cover portion 1142 is connected to the front shell 113 for sound output.

[0255] For ease of explanation, the direction in which the cover 1142 points to the front shell 113 is defined as the first direction D1.

[0256] Please see Figure 9 The front shell 113 includes a front shell surface 1131 and a front shell peripheral surface 1132 surrounding the front shell surface 1131.

[0257] Please see Figure 9 The cover portion 1142 includes a first sub-touch surface 1143 and a first cover surface 1144.

[0258] The first sub-touch surface 1143 is disposed opposite to the front shell surface 1131 of the sound-emitting front shell 113. A first mating surface 1144 connects the first sub-touch surface 1143 and the peripheral side surface 1132 of the front shell of the sound-emitting front shell 113 in a first direction D1. The first mating surface 1144 also connects to the outer surface of the extension 1145 in a second direction D2. The second direction D2 is the direction in which the extension 1145 extends. The first direction D1 and the second direction D2 intersect. Optionally, the angle between the first direction D1 and the second direction D2 is less than or equal to 90°. Optionally, the angle between the first direction D1 and the second direction D2 is close to 90°, so that the extension 1145 can smoothly transition to the curved connector 40.

[0259] One end of the extension 1145 is connected to the side of the cover 1142. The other end of the extension 1145 (along the second direction D2) gradually moves away from the sound-emitting front shell 113.

[0260] For example, the front shell surface 1131 is circular. The peripheral side surface 1132 of the front shell is cylindrical. The first cover surface 1144 is a three-dimensional curved surface, close to a part of a sphere. The first sub-touch surface 1143 is, but is not limited to, a plane, a concave surface, or a convex surface. The dividing line between the first sub-touch surface 1143 and the first cover surface 1144 is the first ridge line 115.

[0261] The curvature of the first sub-touch surface 1143 is much smaller than that of the first cover surface 1144, so that the distance between the first sub-touch surface 1143 and the touch detection module 20 is more uniform. Furthermore, the distance between different touch detection elements 21 and the first sub-touch surface 1143 is more uniform, thereby improving the detection accuracy of different touch detection elements 21.

[0262] This application does not specifically limit the curvature of the first touch surface 112. Optionally, the curvature of the first touch surface 112 is as small as possible, so that the distance between different touch detection elements 21 and the first sub-touch surface 1143 is more uniform, thereby improving the detection accuracy of different touch detection elements 21.

[0263] For example, please see Figure 9 From the first side view of the sound output component 10, the orthographic projection of the first touch surface 112 is a slightly convex arc, which facilitates a smooth transition and connection with the curved connector 40, and also makes it easy to fit the fingertip. It also makes the distance between different touch detection elements 21 and the first sub-touch surface 1143 more uniform, thereby improving the detection accuracy of different touch detection elements 21.

[0264] Please see Figure 10 From the second side view of the sound output component 10, the highest line of the first touch surface 112 is a straight line, which makes the distance between different touch detection elements 21 and the first sub-touch surface 1143 more uniform and improves the detection accuracy of different touch detection elements 21.

[0265] Please see Figure 9The outer surface of the extension 1145 includes a second sub-touch surface 1147 and a first extension surface 1146. The second sub-touch surface 1147 is smoothly connected to the first sub-touch surface 1143. The first extension surface 1146 is a three-dimensional curved surface. One end of the first extension surface 1146 in the second direction D2 is connected to the first cover surface 1144. The other end of the first extension surface 1146 is connected to the connector 40. The first extension surface 1146 is generally a curved surface with a gradually changing cross-sectional area. The first extension surface 1146 and the first cover surface 1144 are smoothly connected. There is no dividing line between the first extension surface 1146 and the first cover surface 1144. There is no dividing line between the first cover surface 1144 and the peripheral side surface 1132 of the front shell. There is no dividing line between the second sub-touch surface 1147 and the first sub-touch surface 1143. The first extension surface 1146 and the peripheral side surface 1132 of the front shell are connected in an arc shape, with a clear dividing line.

[0266] The cross-sectional area of ​​the extension 1145 is smaller than that of the cover 1142. The cross-sectional area of ​​the extension 1145 gradually decreases from the cover 1142 to the extension 1145. The extension direction of the extension 1145 intersects the direction of the cover 1142 pointing towards the sound outlet front shell 113.

[0267] As a further example, the extension 1145 extends in an arc shape. The second sub-touch surface 1147 is the curved outer surface of the extension 1145, and the first extension surface 1146 is the curved inner surface of the extension 1145.

[0268] Please see Figure 9 The first touch surface 112 also includes the aforementioned first sub-touch surface 1143 and the aforementioned second sub-touch surface 1147 that are smoothly connected, so that the area of ​​the first touch surface 112 is relatively large and the length of the first touch surface 112 is relatively large in the direction of the cover portion 1142 pointing to the front shell 113, so as to form different touch areas or form a sliding touch area for sliding operation.

[0269] The first sub-touch surface 1143 is the surface of the cover portion 1142 facing away from the sound-emitting front shell 113. The second sub-touch surface 1147 is located on the extension portion 1145.

[0270] Of course, in other embodiments, the first sub-touch surface 1143 and the second sub-touch surface 1147 may not be smoothly connected and may have ridges between them to form different touch areas.

[0271] As mentioned above, the earphone 100 also includes a connector 40 and a power supply unit 30. The power supply unit 30 is disposed opposite to the sound output front shell 113. The connector 40 is curved. The connector 40 connects the sound output unit 10 and the power supply unit 30.

[0272] Please see Figure 13 The outer surface of the connector 40 includes a second integral surface 41 and a first connecting surface 42 that are connected to each other. The second integral surface 41 is located on the inner side of the bend of the connector 40. The first connecting surface 42 is located on the outer side of the bend of the connector 40. The first connecting surface 42 is smoothly connected to the second sub-touch surface 1147. The second integral surface 41 is smoothly connected to the front shell surface 1131. Further, the second integral surface 41 is smoothly connected to the first extension surface 1146.

[0273] Thus, the extension 1145 not only provides a second sub-touch surface 1147, increasing the area and length of the first touch surface 112, but also facilitates the formation of a long, narrow sliding touch area for easy sliding operation. The increased length of the sliding touch area allows for an increase in the number of touch detection elements 21, thereby improving the accuracy of sliding touch detection and preventing accidental touches.

[0274] Optionally, the ridge line between the front shell surface 1131 and the first touch surface 112 connects to the ridge line between the second integral surface 41 and the first connecting surface 42. The trajectory of the ridge line between the front shell surface 1131 and the first touch surface 112 resembles a teardrop shape.

[0275] Optionally, at least a portion of the touch detection module 20 is disposed on or directly opposite the first connecting surface 42. The touch detection module 20 is also used to sense touch operations on the first connecting surface 42. This further increases the area and length of the touch sensing region, facilitating the formation of a long, narrow sliding touch area for easier sliding operation. The increased length of the sliding touch area allows for an increase in the number of touch detection elements 21, thereby improving the accuracy of sliding touch detection and preventing accidental touches.

[0276] At least a portion of the touch detection module 20 is disposed on or directly opposite the first connection surface 42. The touch detection module 20 is used to sense touch operations on the first connection surface 42.

[0277] Optional, please refer to Figure 20 and Figure 21 The touch detection module 20 further includes at least one second detection element 23. The second detection element 23 is disposed in the second functional area 52 of the flexible circuit board 50. The second functional area 52 of the flexible circuit board 50 is located within the connector 40 and faces the second touch surface 43. The second detection element 23 cooperates with the first detection element 22 for detection or detects independently.

[0278] For example, the first touch surface 112 and the second touch surface 43 can be independent touch surfaces, and the first touch surface 112 and the second touch surface 43 can be non-smoothly connected. The touch operation corresponding to the first touch surface 112 may be the same as or different from the touch operation corresponding to the second touch surface 43.

[0279] For another example, the first touch surface 112 and the second touch surface 43 can form a complete touch surface, and the first touch surface 112 and the second touch surface 43 can be smoothly connected, and a relatively long sliding touch surface can be provided. For example, the first touch surface 112 and the second touch surface 43 form a touch surface with a length greater than 10mm (e.g., 10mm to 20cm), which is conducive to sliding operation and reduces the probability of accidental touch.

[0280] In general, the mainstream control methods for clip-on headphones 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 headphones 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 headphones, compromising their aesthetic appearance. Clip-on headphones are often used during exercise, in environments with high levels of sweat and dust. Combined with the high frequency of physical button operation, dirt easily accumulates from finger touches and is difficult to clean. Clip-on headphones are generally compact, with limited internal space. 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 headphones are worn, leading to malfunctions or unresponsiveness.

[0281] This application incorporates relatively good sliding and other control functions on the main shell of an open-back headphone. Specifically, the surface of the sound-emitting ball (the aforementioned sound-emitting component 10) shell has a relatively suitable surface for users to perform sliding operations. Then, the FPC (flexible circuit board 50) is fixed tightly to the shell on the inner wall of this shell using double-sided adhesive.

[0282] The FPC (Flexible Printed Circuit Board 50) can pass through the pre-drilled holes 44 in the connecting bridge (connector 40) from the sound-emitting ball (the aforementioned sound-emitting component 10) or the battery bead (battery component) to the other end, connecting the three parts of the entire earphone 100 together. Simultaneously, touch functions such as sliding can be implemented on the FPC (Flexible Printed Circuit Board 50) without the need for additional sliding modules. A single FPC (Flexible Printed Circuit Board 50) can connect the core components inside the sound-emitting ball (the aforementioned sound-emitting component 10), such as the speaker, microphone, and VPU, all of which are mounted on this FPC (Flexible Printed Circuit Board 50). Reinforcing plates are added to the back of the FPC (Flexible Printed Circuit Board 50) for the MIC and VPU components. The FPC (Flexible Printed Circuit Board 50) passes through the entire connecting bridge (connector 40) all the way to the battery bead (battery component) end, and is finally soldered to the mainboard inside the battery bead (battery component).

[0283] The sliding area extends across the entire touchable area of ​​the outer surface of the sound-emitting ball (the aforementioned sound-emitting component 10), enabling full-area sliding operation. This area is also convenient for users to perform touch and other control actions. The touchable area on the outer surface of the sound-emitting ball (the aforementioned sound-emitting component 10) is a relatively gentle arc when viewed from all directions; it can be flat, convex, or concave.

[0284] This application provides a novel clip-on earphone with touch-sensitive functions such as sliding on the outer surface of the sound-emitting ball (the aforementioned sound-emitting component 10). To facilitate the sliding function, the controllable area on the outer surface of the sound-emitting ball (the aforementioned sound-emitting component 10) has a relatively smooth and gentle sliding section. The appearance of this sliding section of the sound-emitting ball (the aforementioned sound-emitting component 10) can extend to form an integrated shape with the connecting bridge (connector 40) without affecting the appearance. This effectively avoids the accidental touch problem of open-back earphones and does not disrupt the product's appearance consistency, better meeting the ID requirements for appearance and providing a convenient interactive experience. When the sliding length of the sound-emitting ball (the aforementioned sound-emitting component 10) is insufficient or its size is limited, it is possible to extend part of the sliding area to the connecting bridge (connector 40).

[0285] 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.
