[0030] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0031] Reference to "embodiment" in this application means that a specific feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0032] Combination Figure 1The user's ear EAR may include the external auditory canal E11, the cavum concha E12, the cymba concha E13, the triangular fossa E14, the antihelix E15, the scaphoid E16, the helix E17 and the antitragus E18. Among them, although the external auditory canal 101 has a certain depth and extends to the eardrum, for the convenience of description, and combined with Figure 1 In the present application, unless otherwise specified, the external auditory canal 101 specifically refers to its entrance away from the tympanic membrane (i.e., the ear hole). Furthermore, the concha cavity E12, the hymena concha E13, the triangular fossa E14 and other physiological parts have a certain volume and depth; and the concha cavity E12 is directly connected to the external auditory canal E11, which can be simply regarded as the aforementioned ear hole being located at the bottom of the concha cavity E12.

[0033] Furthermore, there is a tragus E19 outside the external auditory canal of the ear EAR, which has a certain depth and volume in three-dimensional space compared with the cavum concha E12, the cymba concha E13 and the fossa triangularis E14, that is, these parts are respectively concave toward the back of the ear in the direction close to the user's head, and the tragus E19 is convex toward the front of the ear in the direction away from the user's head. Among them, "the front of the ear" is a concept relative to the "back of the ear", the former refers to the side of the ear away from the head, for example Figure 1 , the latter refers to the side of the ear facing the head, and they are all aimed at the user's ears.

[0034] Further, different users may have individual differences, resulting in different shapes, sizes and other size differences in the ears. For the convenience of description, and to reduce (or even eliminate) individual differences between different users, for the convenience of description and understanding, if not otherwise specified, this specification will mainly use an ear model with a "standard" shape and size as a reference to further describe the wearing method of the acoustic device in different embodiments on the ear model. For example, a simulator containing a head and its (left and right) ears, such as GRAS 45BCKEMAR, can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards as a reference for wearing an acoustic device, thereby presenting the scene of most users wearing the acoustic device normally. Just as an example, the ear used as a reference can have the following relevant characteristics: the size of the projection of the auricle on the sagittal plane in the vertical axis direction can be in the range of 49.5mm-74.3mm, and the size of the projection of the auricle on the sagittal plane in the sagittal axis direction can be in the range of 36.6mm-55mm. Therefore, in the present application, descriptions such as "wearing by the wearer", "in a wearing state" and "in a wearing state" may refer to the acoustic device described in the present application being worn on the ear of the aforementioned simulator. Of course, taking into account the individual differences between different users, the structure, shape, size, thickness, etc. of one or more parts of the ear EAR may have certain differences. In order to meet the needs of different users, the acoustic device may be designed differently. These differentiated designs may be manifested in that the characteristic parameters of one or more structures in the acoustic device (for example, the sound-emitting part 10, the ear hook part 30, etc. described below) may have different ranges of values ​​to adapt to different ears.

[0035] It should be noted that in the fields of medicine and anatomy, three basic planes of the human body can be defined: the sagittal plane, the coronal plane, and the horizontal plane, as well as three basic axes: the sagittal axis, the coronal axis, and the vertical axis. Among them, the sagittal plane refers to a plane perpendicular to the ground along the front-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a plane perpendicular to the ground along the left-right direction of the body, which divides the human body into front and back parts; the horizontal plane refers to a plane parallel to the ground along the up-down direction of the body, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis refers to an axis along the front-back direction of the body and perpendicular to the coronal plane, the coronal axis refers to an axis along the left-right direction of the body and perpendicular to the sagittal plane, and the vertical axis refers to an axis along the up-down direction of the body and perpendicular to the horizontal plane. Furthermore, the "front side of the ear" mentioned in this application is a concept relative to the "back side of the ear". The former refers to the side of the ear away from the head, and the latter refers to the side of the ear facing the head. They are both for the user's ear. Among them, by observing the ear of the above simulator along the direction of the human coronal axis, it can be obtained that Figure 1 Based on this, combined with Figure 1 , the three directions of X, Y and Z can be simply regarded as the coronal axis, sagittal axis and vertical axis of the human body respectively; the three planes of XY, XZ and YZ can be simply regarded as the horizontal plane, coronal plane and sagittal plane of the human body respectively.

[0036] See also Figure 2-4The present application proposes an earphone 1, which is an ear clip earphone 1, wherein the earphone 1 includes a sound-generating portion 10 inserted into the concha cavity E12 of the wearer, an abutting portion 20 for abutting the back of the wearer's ear, and an ear hook portion 30 connected to the sound-generating portion 10 and the abutting portion 20. The sound-generating portion 10 is a sound playing device, which is used to convert an electrical signal into an acoustic signal and play it to the wearer, and is located in the concha cavity E12 when worn. Specifically, the abutting portion 20 forms a clamping state with the sound-generating portion 10, so as to abut against the outer side wall of the concha cavity E12 and the inner side wall of the earphone cavity E12 respectively, so as to clamp the entire earphone 1 and wear it on the user's ear EAR. In some embodiments, the abutting portion 20 can be used as a battery 222 compartment for installing a battery 222 or other components. Of course, the abutting portion 20 may not be used as a battery 222 compartment, and the battery 222 may be installed in the sound-generating portion 10. The ear hook portion 30 is a component that provides clamping force. The two ends of the ear hook portion 30 are respectively connected to the sound-emitting portion 10 and the abutment portion 20. When worn, the ear hook portion 30 bypasses the auricle E17 so that the sound-emitting portion 10 and the abutment portion 20 are located on both sides of the human ear along the coronal axis of the human body, and the sound-emitting portion 10 extends to the concha cavity E12 to transmit sound to the ear canal.

[0037] Alternatively, if Figure 4-5 As shown, in some embodiments, the abutment portion 20 includes a first shell 210 component 21, wherein the first shell 210 component 21 includes a first shell 210, the first shell 210 is formed with a accommodating cavity 2101 having a first opening 2102, and the earphone 1 includes an embedding body 22 embedded in the accommodating cavity 2101 via the first opening 2102, wherein the embedding body 22 can be a corresponding component assembly that needs to be installed in the accommodating cavity 2101 on the earphone 1. In this way, the components that need to be set in the accommodating cavity 2101 are integrated and assembled into the embedding body 22, and then embedded in the accommodating cavity 2101 via the first opening 2102, which can effectively improve the assembly efficiency and convenience of the earphone 1. Furthermore, the first shell 210 component 21 also includes a second shell 211, and the second shell 211 can cooperate with the first shell 210 to cover the first opening 2102, thereby sealing the accommodating cavity 2101. In this way, the first shell 210 component 21 forms a closed accommodating cavity 2101 by the mutual cooperation between the first shell 210 and the second shell 211. On the one hand, it can effectively provide an effective sealing environment for the embedded body 22 set in the accommodating cavity 2101, so as to effectively improve the working stability and service life of the embedded body 22. On the other hand, it can also effectively improve the assembly convenience and assembly efficiency of the earphone 1.

[0038] Alternatively, if Figure 6As shown, in some embodiments, the embedded body 22 includes a battery 222, a circuit board assembly 220 and a hard bracket 221.

Furthermore, the hard bracket 221 can provide hard support for the circuit board assembly 220 and the battery 222. During the assembly process, the circuit board assembly 220 and the battery 222 can be spatially arranged on the hard bracket 221, and then the circuit board assembly 220 and the battery 222 can be further arranged in the accommodating cavity 2101 through the hard bracket 221, which can effectively reduce the probability of damage to the circuit board assembly 220 and the battery 222 during the assembly process, thereby effectively improving the production yield of the earphone 1. It should be noted that in some embodiments, the circuit board assembly 220 is also called a main control circuit board.

[0039] Alternatively, if Figure 6 and Figure 7 As shown, in some embodiments, the circuit board assembly 220 includes a rigid circuit board (eg Figure 6 and Figure 7The first hard circuit board 2201 or the second hard circuit board 2202 shown in the figure, the hard circuit board is a plate-like structure of the circuit board assembly 220 for integrated circuit elements, and the circuit elements may include main control circuits and sensors and other elements, wherein the circuit board assembly 220 may be provided with at least one hard circuit board to effectively improve the integration of circuit elements of the earphone 1, thereby effectively improving the space utilization of the earphone 1 while ensuring the functional diversity of the earphone 1. Furthermore, the hard support 221 is provided with a battery accommodating area 2213 and at least one circuit board accommodating area, the battery accommodating area 2213 has a second opening (not marked in the figure), and the circuit board accommodating area has a third opening (not marked in the figure), and the hard circuit board and the battery 222 are respectively arranged in the circuit board accommodating area and the battery 2213 on the hard support 221, so that the hard support 221 can provide better physical protection for the hard circuit board and the battery 222, respectively, so as to effectively protect the circuit elements and the battery 222 on the hard circuit board, thereby effectively reducing the probability of damage to the circuit board assembly 220 and the battery 222 during the assembly process, and thus effectively improving the production yield of the earphone 1. Among them, the hard circuit board and the battery 222 are respectively isolated and arranged in the battery accommodating area 2213 and the circuit board accommodating area, so as to effectively improve the heat dissipation efficiency of the battery 222 and the hard circuit board, thereby effectively improving the working stability of the battery 222 and the circuit elements on the hard circuit board.

Such an arrangement can effectively avoid the spatial position of the battery accommodating area 2213 from interfering with the installation process of the hard circuit board, and avoid the spatial position of the circuit board accommodating area from interfering with the installation process of the battery 222, thereby effectively improving the assembly efficiency of the battery 222 and the hard circuit board.

[0041] Preferably, if Figure 6 and Figure 7As shown, in some embodiments, the circuit board assembly 220 may include two or more rigid circuit boards, and the corresponding rigid bracket 221 is formed with two or more spaced circuit board accommodating areas along the x1 direction, wherein the two or more rigid circuit boards are respectively arranged in the corresponding circuit board accommodating areas, so that the heat dissipation efficiency of each rigid circuit board can be effectively improved, thereby effectively improving the working stability of the circuit elements on each rigid circuit board. For example, in this embodiment, the circuit board assembly 220 includes two rigid circuit boards, namely the first rigid circuit board 2201 and the second rigid circuit board 2202, and the corresponding rigid bracket 221 is formed with two spaced circuit board accommodating areas along the x1 direction, namely the first circuit board accommodating area 2211 and the second circuit board accommodating area 2212, respectively, and the first rigid circuit board 2201 and the second rigid circuit board 2202 are respectively arranged in the first circuit board accommodating area 2211 and the second circuit board accommodating area 2212, so that the working stability of the circuit elements on the first rigid circuit board 2201 and the circuit elements on the second rigid circuit board 2202 can be effectively improved.

[0042] It should be noted that, unless otherwise specified herein, the rigid circuit board may refer to either the first rigid circuit board 2201 or the second rigid circuit board 2202. The corresponding circuit board accommodation area may refer to either the first circuit board accommodation area 2211 or the second circuit board accommodation area 2212. In some embodiments, the first rigid circuit board 2201 is also referred to as a first board body, and the second rigid circuit board 2202 is also referred to as a second board body.

Such a setting can effectively reduce the space occupancy rate of the rigid circuit board and the battery 222 in the x1 direction, thereby effectively improving the space utilization rate of the rigid bracket 221, and further effectively reducing the spatial volume of the embedded body 22.

[0044] Alternatively, if Figure 7 As shown, in some embodiments, the angle between the main surface of the rigid circuit board and the x1 direction is greater than or equal to 80° and less than or equal to 90°. Such a setting can make the main surface of the rigid circuit board as perpendicular to the x1 direction as possible, thereby reducing the space occupancy rate of the rigid circuit board and the battery 222 in the x1 direction, thereby effectively improving the space utilization rate of the rigid bracket 221, and then effectively reducing the spatial volume of the embedded body 22.

[0045] Preferably, if Figure 7 As shown, in some embodiments, the angle between the normal direction z2 of the main surface of the hard circuit board and the axial direction z1 of the battery 222 is set to be less than or equal to 7 degrees, so that the normal direction z2 and the axial direction z1 of the battery 222 are set as parallel as possible, effectively reducing the space occupancy rate of the hard circuit board and the battery 222 in the x1 direction, thereby effectively improving the space utilization rate of the hard bracket 221, and then effectively reducing the spatial volume of the embedded body 22.

Area 2213, the second side plate 221f connects the second end plate 221b and the third end plate 221c to form a first circuit board accommodating area 2211 between the second end plate 221b and the third end plate 221c, the fourth end plate 221d is located on the side of the first end plate 221a away from the second end plate 221b, and is spaced apart from the first end plate 221a along the x1 direction, the third side plate 221g connects the fourth end plate 221d and the first end plate 221a to form a second circuit board accommodating area 2212. Such an arrangement can ensure the structural strength of the hard bracket 221 while effectively reducing the overall mass of the hard bracket 221.

Among them, a plurality of convex rib structures 2217 can be respectively provided on the side walls along the x1 direction of the first end plate 221a, the second end plate 221b, the third end plate 221c and the fourth end plate 221d, so that the convex rib structures 2217 can effectively improve the structural strength of the first end plate 221a, the second end plate 221b, the third end plate 221c and the fourth end plate 221d. In addition, the first end plate 221a, the second end plate 221b, the third end plate 221c and the fourth end plate 221d are plate-like structures. After the one-piece molding process is completed, the first end plate 221a, the second end plate 221b, the third end plate 221c and the fourth end plate 221d need to be cooled, and the convex rib structure 2217 can effectively improve the heat dissipation uniformity of the first end plate 221a, the second end plate 221b, the third end plate 221c and the fourth end plate 221d, thereby effectively preventing the first end plate 221a, the second end plate 221b, the third end plate 221c and the fourth end plate 221d from excessive deformation, collapse and other adverse phenomena during the cooling process, thereby effectively improving the production yield of the hard bracket 221.

Further, the projection of the antenna assembly 2230 along the axial direction z1 of the battery 222 is at least partially overlapped with the end surface 2220 of the battery 222, which can effectively reduce the space occupancy of the antenna assembly 2230 in the radial direction of the battery 222, thereby effectively improving the space utilization of the antenna assembly 2230 and the battery 222 assembly.

Furthermore, after the second antenna portion 224 is grounded, it can effectively disperse the current concentrated on the first antenna portion 223, thereby preventing the current generated based on the RF signal from being completely concentrated on the first antenna portion 223, thereby effectively reducing the SAR value of the antenna assembly 2230. Furthermore, in the present embodiment, the earphone 1 includes a left earphone and a right earphone, and the left earphone and the right earphone can be worn in a way that the left earphone and the right earphone are interchangeable. When the left earphone and the right earphone are interchanged, the relative positions of the first antenna portion 223 and the second antenna portion 224 along the gravity direction change, thereby affecting the clearance rate of the first antenna portion 223 and / or the second antenna portion 224, and further affecting the antenna performance of the first antenna portion 223 and / or the second antenna portion 224.

Furthermore, in some embodiments, the first antenna portion 223 is arranged on a side of the third end plate 221c away from the first circuit board accommodating area 2211, and the second antenna portion 224 is arranged on a side of the fourth end plate 221d away from the second circuit board accommodating area 2212. Such a configuration can effectively improve the clearance rate of the first antenna portion 223 and the second antenna portion 224, while further reducing the interference of the battery 222 to the first antenna portion 223 and the second antenna portion 224, thereby effectively improving the working stability and antenna performance of the antenna assembly 2230.

[0081] Alternatively, if Figure 6-7 As shown, in some embodiments, the circuit board assembly 220 further includes a second flexible circuit board 2204 connected to the first rigid circuit board 2201 and a third flexible circuit board 2205 connected to the second rigid circuit board 2202, the second flexible circuit board 2204 is further connected to the first antenna portion 223, the third flexible circuit board 2205 is further connected to the second antenna portion 224, the second flexible circuit board 2204 provides a circuit trace for the first antenna portion 223 so that the first antenna portion 223 can be connected to the radio frequency unit on the rigid circuit board, and the second antenna portion 224 of the second flexible circuit board 2204 provides a circuit trace so that the second antenna portion 224 can be connected to the radio frequency unit on the rigid circuit board. Such a configuration can effectively improve the convenience of connection between the first antenna portion 223 and the second antenna and the circuit board assembly 220. Preferably, in some embodiments, the second flexible circuit board 2204 extends from one end of the first rigid circuit board 2201 to form a first antenna portion 223 for receiving or transmitting signals, and the third flexible circuit board 2205 extends from one end of the second rigid circuit board 2202 to form a second antenna portion 224 for receiving or transmitting signals. In this configuration, the second flexible circuit board 2204 and the third flexible circuit board 2205 are reused as the first antenna portion 223 and the second antenna portion 224, respectively, which effectively improves the reuse rate of the circuit board assembly 220, thereby effectively simplifying the structure of the headset 1, and further effectively saving the cost of the headset.

[0082] Optionally, in some embodiments, the first antenna portion 223 and the second antenna portion 224 may be spring-type structural members.

[0083] Optionally, in some embodiments, the first antenna portion 223 and the second antenna portion 224 further serve as touch electrodes for receiving touch signals, which can effectively improve the multiplexing rate of the first antenna portion 223 and the second antenna portion 224, thereby effectively simplifying the overall structure of the earphone 1 and effectively reducing the cost of the earphone.

[0084] Preferably, if Figure 2 and Figure 3 As shown, in some embodiments, the sound-emitting portion 10 includes a sound-emitting component (not shown) and a second shell 211 component, the second shell 211 component is used to form a second accommodating space (not shown), the sound-emitting component is arranged in the second accommodating space, the ear hook portion 30 connects the first shell 210 component 21 and the second shell 211 component, and in the wearing state, the first shell 210 component 21 and the second shell 211 component form a clamping state on both sides of the auricle, and the second shell 211 component is located in the concha cavity, the ear hook portion 30 has a symmetry plane aa arranged along the length direction of the ear hook portion 30, and the axial direction z1 of the battery 222 is arranged to intersect with the symmetry plane aa. Specifically, in this embodiment, the earphone 1 is an ear-clip earphone, and the symmetry plane aa of the ear hook portion 30 serves as the symmetry plane aa of the earphone 1. When worn, the symmetry plane aa of the earphone 1 is intersected with the sagittal plane of the human body, and the angle between the symmetry plane aa of the earphone 1 and the sagittal plane of the human body is less than or equal to 90°, and greater than or equal to 80°. Such a setting can effectively ensure that when worn, the axial direction z1 of the battery 222 can be intersected with the horizontal plane of the human body, thereby effectively improving the clearance rate of the antenna assembly 2230, and then effectively improving the antenna performance of the antenna assembly 2230.

[0085] Furthermore, if Figure 2 and Figure 3 As shown, the earphone 1 is configured as a symmetrical structure (at least referring to the overall appearance contour of the earphone 1) symmetrically arranged with the symmetry plane aa of the ear hook portion 30. Based on this configuration, the earphone 1 can be worn in a manner that the left and right ears are interchangeable, and the earphone 1 can ensure good wearing comfort when worn on the left ear or the right ear.

[0086] Preferably, if Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the antenna structure of the first antenna portion 223 is the same as the antenna structure of the second antenna portion 224, and the first antenna portion 223 and the second antenna portion 224 are symmetrically arranged on both sides of the symmetry plane aa. Based on this, when the earphone 1 is worn on the left ear or the right ear, it can ensure that at least one of the first antenna portion 223 and the second antenna portion 224 has a good clearance rate, thereby effectively improving the stability of the antenna assembly 2230.

[0087] Alternatively, if Figure 3 As shown, in some embodiments, the maximum dimension d1 of the first shell 210 component 21 parallel to the symmetry plane aa is smaller than the maximum dimension d2 perpendicular to the symmetry plane aa, so that the first shell 210 component 21 can be arranged in a long column shape as a whole, and the maximum dimension d2 of the first shell 210 component 21 is perpendicular to the symmetry plane aa, which effectively reduces the space occupancy rate of the first shell 210 component 21 in the length direction of the ear hook portion 30, thereby effectively improving the overall space utilization rate of the earphone 1. Furthermore, the joint seam 213 between the first shell 210 and the second shell 211 is arranged to intersect with the symmetry plane aa, and such an arrangement can effectively increase the opening area of ​​the first opening 2102 of the accommodating cavity 2101, thereby effectively improving the assembly efficiency of the embedded body 22 into the accommodating cavity 2101.

[0088] Alternatively, if Figure 5 As shown, in some embodiments, the earphone 1 further includes a soft covering layer, wherein the soft covering layer covers the periphery of the ear hook portion 30 to serve as a part of the ear hook portion 30, and the soft covering layer also covers at least a portion of the periphery of the first shell 210 component 21. Specifically, the soft covering layer covers the periphery of the first shell 210 and the periphery of the ear hook portion 30, and in the wearing state, the first shell 210 abuts against the back side of the ear through the soft covering layer, thereby effectively improving the wearing comfort of the earphone 1.

[0089] Preferably, if Figure 3 As shown, in some embodiments, in the wearing state, the symmetry plane aa of the earphone 1 is arranged to intersect with the sagittal plane, and the angle between the symmetry plane aa of the earphone 1 and the sagittal plane is greater than or equal to 80° and less than or equal to 90°. Such a setting can effectively ensure that the axial direction z1 of the battery 222 intersects with the horizontal plane, thereby effectively improving the clearance rate of the first antenna part 223 and the second antenna part 224, and further improving the performance of the antenna assembly 2230.

[0090] Preferably, if Figure 3 As shown, in some embodiments, when worn, the symmetry plane aa of the earphone 1 is perpendicular to the sagittal plane, that is, the angle between the symmetry plane aa of the earphone 1 and the sagittal plane is set to 90°, and the symmetry plane aa of the earphone 1 is parallel to the horizontal plane. Such a setting can further improve the clearance rate of the antenna assembly 2230, thereby further improving the performance of the antenna assembly 2230.
