[0002] With the increasing popularity of electronic devices, they have become indispensable social and entertainment tools in people's daily lives, and people's demands for these devices are also rising. Headphones, for example, are widely used in daily life, working in conjunction with mobile phones, computers, and other devices to provide users with an auditory feast. Based on their working principle, headphones can generally be divided into air-conduction headphones and bone-conduction headphones; based on how users wear them, they can be divided into over-ear headphones, clip-on headphones, and in-ear headphones; and based on the interaction method between headphones and electronic devices, they can be divided into wired headphones and wireless headphones.

[0003] However, current clip-on headphones are prone to accidental activation by users during use, making them difficult to meet user needs.

Detailed Implementation Methods

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] The reference to "embodiment" in this application 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. 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.

[0027] As shown in Figure 1, the user's ear EAR may include physiological parts such as the external auditory canal E11, the concha E12, the cymba concha E13, the triangular fossa E14, the antihelix E15, the scaphoid fossa E16, the helix E17, and the antitragus E18. While the external auditory canal E11 has a certain depth and extends to the tympanic membrane of the ear EAR, for ease of description and in conjunction with Figure 1, unless otherwise specified, the external auditory canal E11 specifically refers to its entrance (i.e., the ear canal) away from the tympanic membrane. Furthermore, the physiological parts such as the concha E12, cymba concha E13, and triangular fossa E14 have a certain volume and depth; and the concha E12 is directly connected to the external auditory canal E11, meaning the aforementioned ear canal can be simply considered as being located at the bottom of the concha E12.

[0028] Furthermore, the tragus E19 is located around the external auditory canal of the ear EAR. Compared to the concha E12, cymba conchae E13, and triangular fossa E14, it has a certain depth and volume in three-dimensional space. That is, these parts are concave towards the back of the ear EAR along the direction closer to the user's head, while the tragus E19 protrudes towards the front of the ear EAR along the direction away from the user's head. Here, "front of the ear EAR" is a concept relative to "back of the ear EAR". The former refers to the side of the ear EAR away from the head, such as in Figure 1, while the latter refers to the side of the ear EAR facing the head. Both refer to the user's ear EAR.

[0029] Furthermore, individual differences may exist among different users, resulting in variations in the shape, size, and other dimensions of the ear EAR. For ease of description and to minimize (or even eliminate) these individual differences, unless otherwise specified, this specification will primarily use an ear model with a "standard" shape and size as a reference to further describe how the acoustic device in different embodiments is worn on this ear model. For example, a simulator containing a head and its (left and right) ear EARs, such as the GRAS45BCKEMAR, can be manufactured based on ANSI:S3.36, S3.25 and IEC:603187 standards as a reference for wearing the acoustic device, thus representing the scenario of most users normally wearing the acoustic device. As an example only, the ear EAR used for reference may have the following related characteristics: the size of the projection of the auricle in the sagittal plane in the vertical axis direction can be in the range of 49.5 mm to 74.3 mm, and the size of the projection of the auricle in the sagittal plane in the sagittal axis direction can be in the range of 36.6 mm to 55 mm. Therefore, in this application, descriptions such as "worn by the wearer," "in a wearing state," and "under wearing condition" can refer to the acoustic device described in this application being worn on the ear EAR of the aforementioned simulator. Of course, considering individual differences among users, the structure, shape, size, thickness, etc., of one or more parts of the ear EAR can vary to some extent. To meet the needs of different users, the acoustic device can be designed differently. These differentiated designs can manifest as the characteristic parameters of one or more structures in the acoustic device (e.g., the sound-emitting part 100, the connecting part 200, etc., hereinafter referred to as the sound-emitting part 100, etc.) having different ranges of values, thereby adapting to different ear EARs.

[0030] It should be noted that in medicine, anatomy, and other fields, the human body can be defined by three basic planes: the sagittal plane, the coronal plane, and the horizontal plane; and three basic axes: the sagittal axis, the coronal axis, and the vertical axis. The sagittal plane is a section perpendicular to the ground along the anteroposterior direction of the body, dividing the body into left and right parts. The coronal plane is a section perpendicular to the ground along the left-right direction of the body, dividing the body into anterior and posterior parts. The horizontal plane is a section parallel to the ground along the vertical direction of the body, dividing the body into superior and inferior parts. Correspondingly, the sagittal axis is the axis along the anteroposterior direction of the body and perpendicular to the coronal plane; the coronal axis is the axis along the left-right direction of the body and perpendicular to the sagittal plane; and the vertical axis is the axis along the vertical direction of the body and perpendicular to the horizontal plane. Furthermore, the "anterior side of the ear EAR" mentioned in this application is a concept relative to "posterior side of the ear EAR." The former refers to the side of the ear EAR away from the head, while the latter refers to the side of the ear EAR facing the head; both refer to the user's ear EAR. Specifically, observing the ear EAR of the simulator along the direction of the human coronal axis yields the anterior contour diagram of the ear EAR shown in Figure 1. Based on this, and referring to Figure 1, the X, Y, and Z directions can be simply considered as the human coronal axis, the human sagittal axis, and the human vertical axis, respectively; the XY, XZ, and YZ planes can be simply considered as the human horizontal plane, the human coronal plane, and the human sagittal plane, respectively.

[0031] Referring to Figures 1, 2, and 3, this application proposes an earphone 1, which is an ear clip-on earphone 1. The earphone 1 includes a sound-emitting part 100 inserted into the wearer's concha E12, an abutment part 300 for abutting against the back of the wearer's ear, and a connecting part 200 connecting the sound-emitting part 100 and the abutment part 300. The sound-emitting part 100 is a sound playback device used to convert electrical signals into sound signals and play them to the wearer. In the wearing state, it is located in the concha E12. Specifically, the abutment part 300 and the sound-emitting part 100 form a clamping state, abutting against the back of the ear and the inner wall of the concha E12 respectively, so as to clamp the entire earphone 1 onto the user's ear. In some embodiments, the abutment part 300 can be used as a battery compartment for installing a battery 700 or other components. Of course, the abutment part 300 may also not be used as a battery compartment, and the battery 700 may be installed in the sound-emitting part 100. The connecting part 200 is a component that provides clamping force. The two ends of the connecting part 200 are connected to the sound-emitting part 100 and the abutment part 300, respectively. In the wearing state, the connecting part 200 passes around the helix E17 so that the sound-emitting part 100 and the abutment part 300 are located on both sides of the human ear EAR along the coronal axis of the human body, and the sound-emitting part 100 extends to the concha cavity E12 to transmit sound to the ear canal.

[0032] In some embodiments, as shown in FIG3, the earphone 1 includes a first housing 31, a first touch detection element 32, a second touch detection element 33, and a processing circuit 400. Optionally, the abutment portion 300 includes the first housing 31, which carries the first touch detection element 32 and the second touch detection element 33. The first housing 31 has a first touch area 301 and a second touch area 302 that are spaced apart from each other and disposed opposite to each other. The first touch detection element 32 generates a first touch indication signal in response to the capacitance change caused by the user's touch action in the first touch area 301, and the second touch detection element 33 generates a second touch indication signal in response to the capacitance change caused by the user's touch action in the second touch area 302.

[0033] The user's touch actions can include, for example, simultaneously pressing the first touch area 301 and the second touch area 302, i.e., continuously contacting the first touch area 301 and the second touch area 302; simultaneously tapping the first touch area 301 and the second touch area 302; or pressing one of the first touch area 301 and the second touch area 302 while simultaneously tapping the other. The processing circuit 400 can be a circuit board or a circuit board assembly, used to generate control commands based on the first touch indication signal and the second touch indication signal and preset command generation logic. The control commands can be used, for example, to control the headphones 1 to stop or pause music playback, start music playback, switch to the next song in the playlist, switch to the previous song in the playlist, etc. The first touch detection element 32 and the second touch detection element 33 can be capacitive touch sensors or resistive touch sensors, and of course, other touch detection elements can also be used.

[0034] By setting a first touch detection element 32 and a second touch detection element 33, and by setting a first touch area 301 and a second touch area 302 on the first housing 31 at intervals and opposite to the first touch detection element 32 and the second touch detection element 33 respectively, the processing circuit 400 generates control commands according to a preset command generation logic based on a first touch indication signal indicating that the user touches the first touch area 301 and a second touch indication signal indicating that the user touches the second touch area 302, so as to control the headset 1 accordingly. This can effectively prevent the headset 1 from being accidentally touched, effectively improve the accuracy of the headset 1 in detecting the user's touch operation, effectively improve the control accuracy of the headset 1, enrich the interactive functions of the headset 1, and enhance the applicability of the headset 1.

[0035] Optionally, as shown in Figure 1, in the wearing state, the first shell 31 is located on the back side of the user's earlobe E17, and the spacing direction F3 between the first touch area 301 and the second touch area 302 intersects with the user's horizontal plane. This arrangement makes it easier for the user to touch the first touch area 301 and the second touch area 302, which helps to improve the user's touch convenience and comfort.

[0036] In some embodiments, as shown in FIG4, the abutment portion 300 includes a first housing 31, and the sound-emitting portion 100 includes a second housing 11. The first housing 31 carries a first touch detection element 32, and the second housing 11 carries a second touch detection element 33. The side of the first housing 31 opposite to the earlobe E17 has a first touch area 301, and the side of the second housing 11 opposite to the earlobe E17 has a second touch area 302. The first touch detection element 32 generates a first touch indication signal in response to the capacitance change caused by the user's touch action in the first touch area 301. The second touch detection element 33 generates a second touch indication signal in response to the capacitance change caused by the user's touch action in the second touch area 302. The processing circuit 400 is used to generate control commands based on the first touch indication signal, the second touch indication signal, and a preset command generation logic.

[0037] By setting the first touch area 301 and the second touch area 302 respectively on the side of the contact part 300 and the sound-emitting part 100 away from the ear helix E17, mutual interference between the first touch area 301 and the second touch area 302 is effectively avoided, and it is convenient for users to touch. It effectively prevents accidental touch of the earphone 1 and effectively improves the accuracy of the earphone 1 in detecting user touch operations.

[0038] The following is an exemplary description of how the processing circuit 400 generates control instructions based on a preset instruction generation logic.

[0039] In some embodiments, the instruction generation logic is configured to generate a first control instruction in response to a first touch indication signal and a second touch indication signal respectively instructing the user to continuously touch the first touch area 301 and the second touch area 302. For example, when the user simultaneously presses the first touch area 301 and the second touch area 302, i.e., continuously touches the first touch area 301 and the second touch area 302, the first touch detection element 32 and the second touch detection element 33 respectively generate the first touch indication signal and the second touch indication signal, and the processing circuit 400 generates the first control instruction based on the first touch indication signal, the second touch indication signal and the instruction generation logic.

[0040] In some embodiments, the instruction generation logic is configured to generate a second control instruction in response to a first touch indication signal instructing a user to continuously touch the first touch area 301, while a second touch indication signal instructs the user to tap the second touch area 302. For example, when a user presses the first touch area 301, i.e., continuously touches the first touch area 301, and simultaneously taps the second touch area 302, the first touch detection element 32 and the second touch detection element 33 respectively generate the first touch indication signal and the second touch indication signal, and the processing circuit 400 generates the second control instruction based on the first touch indication signal, the second touch indication signal, and the instruction generation logic.

[0041] In some embodiments, the instruction generation logic is configured to generate a third control instruction in response to a first touch indication signal and a second touch indication signal respectively instructing the user to tap the first touch area 301 and the second touch area 302. For example, when the user simultaneously taps the first touch area 301 and the second touch area 302, the first touch detection element 32 and the second touch detection element 33 respectively generate the first touch indication signal and the second touch indication signal, and the processing circuit 400 generates the third control instruction based on the first touch indication signal, the second touch indication signal, and the instruction generation logic.

[0042] Optionally, the first, second, and third control instructions can be used to control the same function of the headphones 1, or they can control different functions of the headphones 1 respectively. For example, the first, second, and third control instructions can all be used to control the headphones 1 to play music, or to control the pause of music playback while the headphones 1 is playing music. As another example, the first control instruction can be used to control the headphones 1 to turn on and off, the second control instruction can be used to control the headphones 1 to switch music tracks, and the third control instruction can be used to control the playback and pause of music on the headphones 1. Of course, the first, second, and third control instructions can also be used to implement other control functions; this application does not limit this, and those skilled in the art can choose according to actual needs.

[0043] By configuring the processing circuit 400 to generate control commands based on the first touch indication signal, the second touch indication signal, and a preset command generation logic, and by generating different control commands when the user operation indicated by the first touch indication signal and the second touch indication signal is different, the interactive functions of the headset 1 are enriched while effectively preventing accidental touches. Users can achieve diverse control of the headset 1 through touch, which helps to improve the applicability of the headset 1.

[0044] Optionally, the processing circuit 400 is configured to generate a control command based on a preset command generation logic when it confirms that the first touch indication signal and the second touch indication signal are greater than a first threshold and a second threshold, respectively. By setting the first threshold and the second threshold, the touch operation of the user touching the first touch area 301 and the second touch area 302 can be effectively monitored, effectively reducing the possibility of control errors caused by the user accidentally touching the first touch area 301 and the second touch area 302, effectively improving the accuracy of detecting the user's touch operation, and effectively improving the control accuracy of the earphone 1.

[0045] Optionally, as shown in Figure 5, the earphone 1 further includes a wearing detection element 500, which is used to detect whether the earphone 1 is in a wearing state or a non-wearing state. The processing circuit 400 is configured to select different instruction generation logics when the earphone 1 is in a wearing state or a non-wearing state, wherein the same first touch indication signal and second touch indication signal generate different control signals through different instruction generation logics. For example, when the wearing detection element 500 detects that the earphone 1 is in a wearing state, if the first touch indication signal and the second touch indication signal respectively indicate that the user continues to touch the first touch area 301 and the second touch area 302, then the processing circuit 400 generates a control command to control the music to pause on the earphone 1 according to the instruction generation logic; while when the wearing detection element 500 detects that the earphone 1 is in a non-wearing state, if the first touch indication signal and the second touch indication signal respectively indicate that the user continues to touch the first touch area 301 and the second touch area 302, then the processing circuit 400 generates a control command to control the earphone 1 to turn off according to the instruction generation logic.

[0046] By setting up a wear detection element 500 and setting up instruction generation logic adapted to different wearing states, it is beneficial to enrich the interactive functions of the headset 1, provide users with more diversified control mechanisms, and enhance the fun and convenience of using the headset 1.

[0047] Optionally, as shown in Figure 5, the earphone 1 further includes left and right ear detection elements 600, which are used to detect whether the earphone 1 is worn on the left or right ear. The processing circuit 400 is configured to select different instruction generation logic when the earphone 1 is worn on the left or right ear, wherein the same first touch indication signal and second touch indication signal generate different control signals through different instruction generation logics. For example, when the left and right ear detection element 600 detects that the earphone 1 is worn on the left ear, if the first touch indication signal and the second touch indication signal respectively indicate that the user taps the first touch area 301 and the second touch area 302, then the processing circuit 400 generates a control instruction to control the earphone 1 to switch to the previous song in the playlist according to the instruction generation logic; while when the left and right ear detection element 600 detects that the earphone 1 is worn on the right ear, if the first touch indication signal and the second touch indication signal respectively indicate that the user taps the first touch area 301 and the second touch area 302, then the processing circuit 400 generates a control instruction to control the earphone 1 to switch to the next song in the playlist according to the instruction generation logic.

[0048] By setting up left and right ear detection elements 600 and setting up instruction generation logic adapted to wearing the left and right ears respectively, diversified control of the earphone 1 can be achieved, which is conducive to enriching the interactive functions of the earphone 1 and improving the fun and convenience of using the earphone 1.

[0049] Optionally, as shown in Figure 5, the earphone 1 includes a wearing detection element 500 and left and right ear detection elements 600. The left and right ear detection elements 600 are gravity sensors. The wearing detection element 500 is used to detect whether the earphone 1 is in a wearing state or not. The processing circuit 400 is configured to trigger the detection function of the left and right ear detection elements 600 when the earphone 1 is in a wearing state.

[0050] By simultaneously setting up the wearing detection element 500 and the left and right ear detection elements 600, it is possible to further detect whether the earphone is worn in the left or right ear only when the user wears the earphone 1, and then use the corresponding instruction generation logic to effectively reduce the possibility of the earphone 1 being accidentally touched when it is placed in a pocket or on a table, and further improve the control accuracy of the earphone 1.

[0051] Optionally, as shown in Figures 6 and 7, the earphone 1 further includes a battery 700 disposed within the first housing 31. The battery 700 is cylindrical, for example, a square or rectangular cylinder with a circular base. The axial direction F1 of the battery 700 is defined as the extending direction perpendicular to the base of the cylindrical body. For example, in this embodiment, the battery 700 is cylindrical, and the axial direction F1 is defined as the extending direction perpendicular to the end face 701 of the battery 700.

[0052] Optionally, as shown in Figures 6 and 7, the first touch detection element 32 and the second touch detection element 33 are respectively arranged in a sheet shape and spaced apart at both ends of the battery 700 along the axial direction F1. This arrangement can effectively improve the space utilization rate inside the first housing 31, improve the structural integration and compactness of the earphone 1, and effectively reduce the interference of the battery 700 on the first touch detection element 32 and the second touch detection element 33, thereby improving the performance of the first touch detection element 32 and the second touch detection element 33 and improving the accuracy of touch detection of the earphone 1. Furthermore, the projections of the first touch detection element 32 and the second touch detection element 33 along the axial direction F1 of the battery 700 are respectively at least partially overlapping with the end face 701 of the battery 700. This arrangement can effectively reduce the radial space occupation of the first touch detection element 32 and the second touch detection element 33 on the battery 700, thereby effectively improving the space utilization rate inside the first housing 31. Optionally, the first touch area 301 and the second touch area 302 are respectively disposed opposite to the first touch detection element 32 and the second touch detection element 33, that is, the first touch area 301 and the second touch area 302 are disposed at intervals along the axial direction F1 of the battery 700 on the first housing 31.

[0053] Optionally, the ratio of the overlapping area of ​​the first touch detection element 32 and the end face 701 of the battery 700 to the main surface area of ​​the first touch detection element 32 is greater than or equal to 0.9, for example, it can be 0.92, 0.95, 0.98, etc., or other values. Similarly, the ratio of the overlapping area of ​​the second touch detection element 33 and the end face 701 of the battery 700 to the main surface area of ​​the second touch detection element 33 is greater than or equal to 0.9, for example, it can be 0.92, 0.95, 0.98, etc., or other values. The overlapping area of ​​the first touch detection element 32 with the end face 701 of the battery 700, that is, the overlapping area of ​​the projection of the first touch detection element 32 along the axial direction F1 of the battery 700 with the end face 701 of the battery 700, is the same as the overlapping area of ​​the second touch detection element 33 with the end face 701 of the battery 700, that is, the overlapping area of ​​the projection of the second touch detection element 33 along the axial direction F1 of the battery 700 with the end face 701 of the battery 700. This arrangement can effectively reduce the space occupied by the first touch detection element 32 and the second touch detection element 33 along the radial direction of the battery 700, thereby effectively improving the space utilization rate among the first touch detection element 32, the second touch detection element 33, and the battery 700. Preferably, in some embodiments, the overlapping area of ​​the first touch detection element 32 and the end face 701 of the battery 700 can be equal to the total projected area of ​​the first touch detection element 32 along the axial direction F1 of the battery 700, that is, the ratio of the overlapping area of ​​the first touch detection element 32 and the end face 701 of the battery 700 to the total projected area of ​​the first touch detection element 32 along the axial direction F1 of the battery 700 is equal to 1. Similarly, the overlapping area of ​​the second touch detection element 33 and the end face 701 of the battery 700 can be equal to the total projected area of ​​the second touch detection element 33 along the axial direction F1 of the battery 700, that is, the ratio of the overlapping area of ​​the second touch detection element 33 and the end face 701 of the battery 700 to the total projected area of ​​the second touch detection element 33 along the axial direction F1 of the battery 700 is equal to 1.

[0054] Further, as shown in Figures 6 and 7, the angles between the normal direction of the main surface of the first touch detection element 32 and the axial direction F1 of the battery 700, and the angles between the normal direction of the main surface of the second touch detection element 33 and the axial direction F1 of the battery 700, are respectively less than or equal to 10°, for example, 3°, 5°, 8°, etc., and of course, other values ​​are also possible. This arrangement allows the main surfaces of the first touch detection element 32 and the second touch detection element 33 to be arranged as parallel as possible to the end face 701 of the adjacent battery 700, thereby further improving the space utilization rate among the battery 700, the first touch detection element 32, and the second touch detection element 33. For example, in some embodiments, the angles between the normal direction of the main surface of the first touch detection element 32 and the axial direction F1 of the battery 700, and the angles between the normal direction of the main surface of the second touch detection element 33 and the axial direction F1 of the battery 700, can be set to 0°.

[0055] Optionally, as shown in Figures 2 and 3, the earphone 1 further includes a second housing 11, a connecting portion 200, and a sound-generating component 12. Optionally, the earphone 1 includes a sound-generating portion 100, which includes a second housing 11. The sound-generating component 12 is disposed within the second housing 11 and is used to generate sound under the control of the processing circuit 400 and transmit it outside the second housing 11. The connecting portion 200 connects the first housing 31 and the second housing 11 to achieve a connection between the abutment portion 300 and the sound-generating portion 100. In the wearing state, the first housing 31 and the second housing 11 form a clamping state on both sides of the auricle, and the second housing 11 is located within the concha cavity E12. The connecting portion 200 has a symmetrical plane SF disposed along the length direction F2 of the connecting portion 200. The axial direction F1 of the battery 700 intersects with the symmetrical plane SF, effectively improving the wearing comfort of the earphone 1 while facilitating user operation and touch control of the earphone 1.

[0056] The symmetry plane SF of the connecting part 200 refers to the plane set along the length direction F2 of the connecting part 200, and the difference between the connecting parts 200 on both sides of the symmetry plane SF is minimal or consistent. That is, if the connecting part 200 is regularly symmetrical, then the connecting parts 200 on both sides of the symmetry plane SF are consistent. If the connecting part 200 is not strictly symmetrical, then the difference between the connecting parts 200 on both sides of the symmetry plane SF should be minimal among various division methods. For example, the size of the difference can be distinguished by observing the projection of the connecting part 200 on a plane perpendicular to the symmetry plane SF.

[0057] Furthermore, as shown in Figure 3, the earphone 1 is configured with a symmetrical structure (at least referring to the overall appearance outline of the earphone 1) symmetrically arranged with the symmetrical plane SF of the connecting part 200. Based on this configuration, the earphone 1 can be adapted to both left and right ear wear at the same time, and can ensure good wearing comfort when the earphone 1 is worn in either the left or right ear.

[0058] Optionally, as shown in Figure 1, in this embodiment, the earphone 1 is an ear clip-on earphone 1, with the symmetry plane SF intersecting the user's sagittal plane. The angle between the symmetry plane SF and the sagittal plane is greater than or equal to 72° and less than or equal to 90°, for example, 75°, 80°, 85°, etc., or other values. This setting effectively ensures that, when worn, the axis F1 of the battery 700 intersects with the horizontal plane of the human body, allowing the user to conveniently and freely touch the first touch area 301 and the second touch area 302, which improves the convenience of touch control of the earphone 1 and enhances the comfort of using the earphone 1.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
