[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0026] Reference to “an embodiment” in this application means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present application can be combined with other embodiments.

[0027] The following is an exemplary description of the earphone embodiment to the earphone.

[0028] In conjunction with Figure 1 , the ear 100 of a user can include physiological sites such as the external auditory canal 101, the concha cavity 102, and the auricle 103. Among them, although the external auditory canal 101 has a certain depth and extends to the tympanic membrane of the ear 100, for the convenience of description, the external auditory canal 101 specifically refers to the entrance (i.e., the ear hole) thereof away from the tympanic membrane without special indication. In addition, the concha cavity 102 has a certain volume and depth, and the concha cavity 102 is directly communicated with the external auditory canal 101, that is, the aforementioned ear hole can be simply regarded as located at the bottom of the concha cavity 102.

[0029] The earphone 1 is an audio converter capable of receiving electrical signals emitted from a media player or a receiver and converting the electrical signals into sound waves that can be heard by a user. In some embodiments, the earphone 1 can be an open earphone, such as an ear hook earphone, a back hook earphone, or an ear clip earphone, etc.

[0030] As Figure 2 or Figure 3As shown, the earphone 1 can be an over-ear earphone. In some embodiments, at least a portion of the earphone 1 can be inserted into the concha cavity 102 of the user (wearer) in the wearing state, so as to improve the stability of wearing. In some embodiments, the sound generating part of the earphone 1 can at least partially cover the pinna 103 of the user's ear, such as the position of the helix, the cymba concha, or the triangular fossa (not shown in the figure), but does not block or visually obstruct the external auditory canal 101 of the user's ear. In some embodiments, the sound generating part 20 of the earphone 1 can also be attached to or abut against the facial area in front of the user's ear, and the side of the sound generating part 20 used for sound generation faces the user's ear or the user's external auditory canal 101.

[0031] Further, different users can have individual differences, resulting in different sizes of the ear 100, such as different shapes and sizes. In order to facilitate description and reduce (or even eliminate) individual differences of different users, a simulator containing a head and its (left and right) ear 100 can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BC KEMAR, HEAD Acoustics, B&K 4128 series or B&K 5128 series, so as to present the scenario of most users wearing the earphone 1. Taking GRAS KEMAR as an example, the simulator of the ear 100 can be any one of GRAS 45AC, GRAS 45BC, GRAS 45CC or GRAS 43AG; taking HEAD Acoustics as an example, the simulator of the ear 100 can be any one of HMS II.3, HMS II.3LN or HMS II.3LN HEC. Therefore, in this application, descriptions such as "the user wears the earphone 1", "the earphone 1 is in the wearing state" and "in the wearing state" can refer to the earphone 1 described in this application being worn on the ear 100 of the aforementioned simulator. Of course, because different users have individual differences, the earphone 1 worn by different users may have some differences from the earphone 1 worn on the ear 100 of the aforementioned simulator, but such differences should be tolerated.

[0032] It should be noted that in the field of medicine, anatomy, etc., three basic planes of the human body or human body simulator can be defined, namely, a sagittal plane, a coronal plane and a horizontal plane, and three basic axes, namely, a sagittal axis, a coronal axis and a vertical axis. The sagittal plane refers to a plane perpendicular to the ground made in the front-to-back direction of the body, which divides the human body or human body simulator into two parts; the coronal plane refers to a plane perpendicular to the ground made in the left-to-right direction of the body, which divides the human body or human body simulator into two parts; and the horizontal plane refers to a plane parallel to the ground made in the up-to-down direction of the body, which divides the human body or human body simulator into two parts. Correspondingly, the sagittal axis refers to an axis perpendicular to the coronal plane in the front-to-back direction of the body, the coronal axis refers to an axis perpendicular to the sagittal plane in the left-to-right direction of the body, and the vertical axis refers to an axis perpendicular to the horizontal plane in the up-to-down direction of the body. Further, the "front side of the ear" is a concept relative to the "rear 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 towards the head, both of which are for the ear 100 of the user or the simulator. As shown in Figure 1 .

[0033] As an example, in combination with Figure 2 and Figure 3 , the earphone 1 can include the ear hook 10 and the sound emitting part 20 connected to each other. In the wearing state, the ear hook 10 can be hung between the auricle 103 and the head of the user, that is, at least part of the ear hook 10 of the earphone 1 can be located at the rear side of the ear 100, so that the earphone 1 is hung on the ear 100, and the sound emitting part 20 can be located at the front side of the auricle 103. The sound emitting part 20 can be a sound playing device, which can be used to convert an electrical signal into an acoustic signal (also referred to as "sound wave" or "sound signal") and propagate to the ear 100 of the wearer.

[0034] In some embodiments, the ear hook 10 can be provided with a battery or a circuit board or the like, or the ear hook 10 can be provided with both a battery and a circuit board. Of course, the ear hook 10 can also not be provided with a battery and a circuit board or the like, and the battery and the circuit board or the like can be installed in the sound emitting part 20.

[0035] In some embodiments, as shown in Figure 2 and Figure 3As shown, the sound production part 20 can include a core housing 210. In some embodiments, the earphone 1 can further include a speaker assembly 30 disposed in the core housing 210. The speaker assembly 30 is a component that can convert an electrical signal into a corresponding acoustic signal to realize the sound playing function of the sound production part 20. As an example, the speaker assembly 30 can include a bone conduction speaker and an air conduction speaker, and in other embodiments, the speaker assembly 30 can also be provided as one of the air conduction speaker and the bone conduction speaker.

[0036] In some embodiments, as shown in Figure 2 and Figure 3 As shown, the ear hook 10 can include an adapter housing 110 and a hook portion 120, the adapter housing 110 being used to connect the core housing 210 and the hook portion 120. The hook portion 120 can be in the shape of a hook, so that the user can hook it on the ear 100 of the user when wearing the earphone 1.

[0037] In some embodiments, as shown in Figure 4 to Figure 7 As shown, the earphone 1 can include a terminal assembly 40 and a master control circuit board 50, the core housing 210 has a pressing area 211, the adapter housing 110 has a bearing area 111, and in the state that the adapter housing 110 and the core housing 210 are connected to each other, the bearing area 111 and the pressing area 211 are arranged in a stacked manner, the terminal assembly 40 is disposed between the pressing area 211 and the bearing area 111 and is clamped by the pressing area 211 and the bearing area 111, and part of the terminal assembly 40 is exposed outside the adapter housing 110 of the earphone 1 through the first through hole 1111 of the bearing area 111.

[0038] The terminal assembly 40 includes an electrode terminal 41. Part of the electrode terminal 41 can be exposed to the outer surface of the adapter housing 110 of the earphone 1 through the first through hole 1111, and the other part is electrically connected to the master control circuit board 50, so that the earphone 1 can be electrically connected to the internal circuit of the charging box through the terminal assembly 40, so that the charging box can charge the earphone 1 through the terminal assembly 40.

[0039] In some embodiments, the terminal assembly 40 can further include a detection terminal (not shown in the figure), which facilitates the earphone 1 to realize detection functions such as charging detection, earphone 1 put into or taken out of the charging box detection, etc.

[0040] Specifically, when the core shell 210 is connected with the adapter shell 110, the terminal assembly 40 is clamped by the pressing area 211 and the bearing area 111 to be fixed in the earphone 1, and part of the terminal assembly 40 is exposed outside through the first through hole 1111 of the bearing area 111. In this way, on the one hand, the terminal assembly 40 can be stably fixed in the earphone 1 through the mutual clamping action of the pressing area 211 of the core shell 210 and the bearing area 111 of the adapter shell 110, without the need for additional support structure to stabilize the terminal assembly 40, thereby simplifying the structure inside the earphone 1, reducing the assembly difficulty of the earphone 1, reducing the size of the earphone 1, and improving the space utilization and structural stability inside the earphone 1. At the same time, the terminal assembly 40 can block the first through hole 1111 under the action of the pressing area 211 and the bearing area 111, thereby reducing the risk of damage and corrosion of the components inside the earphone 1 caused by the entry of external moisture, dust particles and other impurities through the first through hole 1111.

[0041] In some embodiments, as shown in Figure 4 The bearing area 111 can be provided with a mounting groove 1112, and the first through hole 1111 is arranged at the bottom of the mounting groove 1112 and penetrates the adapter shell 110. The terminal assembly 40 can be pressed and held in the mounting groove 1112 by the pressing area 211. In this way, the terminal assembly 40 can be limited by the mounting groove 1112 to further limit the freedom of the terminal assembly 40 in the direction of being pressed, thereby reducing the risk of unstable electrical connection caused by the movement of the terminal assembly 40 and improving the charging efficiency of the earphone 1.

[0042] In some embodiments, as shown in Figure 4 The terminal assembly 40 can include a plurality of electrode terminals 41 and a support plate 42. The plurality of electrode terminals 41 can be arranged in an array on one side of the support plate 42, and electrically connected to the first wire 21 through the support plate 42. The plurality of electrode terminals 41 are connected to the main control circuit board 50 in the core shell 210 through the first wire 21. The first wire 21 can be a flexible circuit board, a wire, or other structures or modules that can transmit current. The number of first through holes 1111 corresponds to the number of electrode terminals 41, and part of each electrode terminal 41 is exposed through the corresponding first through hole 1111. By fixing the plurality of electrode terminals 41 with the support plate 42, the plurality of electrode terminals 41 can be regularly and uniformly arranged to ensure the consistency and stability of electrical connection. The support plate 42 can be entirely made of conductive metal or plastic material, or partially made of conductive metal material and partially made of non-conductive plastic material.

[0043] Specifically, the support plate 42 is installed in the installation groove 1112. The shape of the installation groove 1112 and the position shape of the first through hole 1111 can be adapted to the shape of the terminal assembly 40 to facilitate the placement of the terminal assembly 40 on the bearing area 111, thereby improving the assembly convenience of the terminal assembly 40.

[0044] The core shell 210 can have a thickness direction, which is the direction of the core shell 210 in the wearing state in which the sound emitting part 20 faces or faces away from the auricle 103. The included angle between the stacking direction of the bearing area 111 and the pressing holding area 211 and the thickness direction is not more than 5°.

[0045] As an example, the stacking direction of the bearing area 111 and the pressing holding area 211 can be in the direction shown by arrow C, and the thickness direction can be in the direction shown by arrow Z. Figure 7 As an example, the stacking direction of the bearing area 111 and the pressing holding area 211 can be in the direction shown by arrow C, and the thickness direction can be in the direction shown by arrow Z. Figure 7 As an example, the included angle between the stacking direction C of the bearing area 111 and the pressing holding area 211 and the thickness direction Z can be 0°, 1°, 2.5°, 4°, or 4.5°, etc.

[0046] If the included angle between the stacking direction C of the bearing area 111 and the pressing holding area 211 and the thickness direction Z is set to be more than 5°, the bearing area 111 and the pressing holding area 211 and the terminal assembly 40 will occupy a larger space in the thickness direction Z. Moreover, the excessive inclination of the stacking direction C of the bearing area 111 and the pressing holding area 211 relative to the thickness direction Z will also increase the lateral force of the terminal assembly 40, increase the installation difficulty of the terminal assembly 40, and affect the service life of the terminal assembly 40.

[0047] Therefore, by setting the included angle between the stacking direction C of the bearing area 111 and the pressing holding area 211 and the thickness direction Z to be not more than 5°, not only can the occupied space of the bearing area 111, the pressing holding area 211 and the terminal assembly 40 in the thickness direction Z be reduced, the size of the earphone 1 in the thickness direction Z can be reduced, but also the installation difficulty of the terminal assembly 40 can be reduced.

[0048] In some embodiments, as shown in Figure 4 to Figure 7 The core shell 210 has a first annular abutting edge 212, and the adapter shell 110 has a second annular abutting edge 112. When the core shell 210 and the adapter shell 110 are connected, the first annular abutting edge 212 and the second annular abutting edge 112 can abut each other. The projection of the bearing area 111 and the pressing holding area 211 along the stacking direction can fall inside the first annular abutting edge 212 and the second annular abutting edge 112.

[0049] Specifically, the first and second annular abutting edges 212 and 112 can present irregular annular structures, and the movement core housing 210 and the adapter housing 110 can be abutted and fixed to each other through the annular first and second annular abutting edges 212 and 112. In this way, the connection and fixing structure of the movement core housing 210 and the adapter housing 110 can be simplified, and the annular abutting structure can also make the connection of the ear hook 10 and the sound generating part 20 more stable, thereby improving the structural stability of the earphone 1.

[0050] Further, since the first and second annular abutting edges 212 and 112 are abutted to each other, the bearing area 111 and the pressing area 211 are also pressed to each other in the stacking direction, and thus the pressure generated by the abutting of the first and second annular abutting edges 212 and 112 can affect the stacking pressure between the bearing area 111 and the pressing area 211. Therefore, in the stacking direction of the bearing area 111 and the pressing area 211, the projection of the bearing area 111 and the pressing area 211 along the stacking direction falls within the first and second annular abutting edges 212 and 112, which can strengthen the pressing force of the bearing area 111 and the pressing area 211 on each other in the stacking direction C, so that the bearing area 111 and the pressing area 211 can strengthen the clamping force on the terminal assembly 40, so that the terminal assembly 40 is more stable, thereby improving the tightness and stability of the internal structure of the earphone 1.

[0051] In some embodiments, as shown in Figure 2 and Figure 3 The movement core housing 210 can have a thickness direction, a width direction and a length direction orthogonal to each other. The movement core housing 210 has a connection end 213 for connecting the ear hook 10 and a free end 214 opposite to the connection end 213. In the wearing state, at least part of the free end 214 can extend into the concha cavity 102 or abut against the auricle 103 of the user.

[0052] The length direction can be the spacing direction of the connection end 213 and the free end 214. The spacing direction of the connection end 213 and the free end 214 refers to the extension direction of the line between the connection end 213 and the free end 214. In some embodiments, the connection end 213 and the free end 214 can be irregular or regular circular arcs, and the extension direction of the line between the connection end 213 and the free end 214 can refer to the direction defined by the straight line perpendicular to the parallel tangent plane of the two reference points with the largest distance on the connection end 213 and the free end 214. The length direction can also be defined as the direction of the movement core housing 210 approaching or moving away from the back of the head in the wearing state, i.e. the direction defined between the side of the movement core housing 210 approaching the back of the head and the side moving away from the back of the head in the wearing state. As an example, the length direction can be as shown in Figure 2 to Figure 7the direction indicated by the middle arrow X. It should be noted that in the present specification, the length direction, the width direction and the thickness direction of the core housing 210 defined by the wearing state are all based on the core housing 210, and are independent of the three basic axes of the human body, and are not changed due to the slight differences when worn on the ears of different users.

[0053] The width direction can be defined as the direction in which the core housing 210 is close to or away from the top of the head in the wearing state, that is, the direction defined between the side of the core housing 210 close to the top of the head and the side away from the top of the head in the wearing state. As an example, the width direction can be as shown in Figure 2 to Figure 7 the direction indicated by the middle arrow Y. Among them, the thickness direction Z, the width direction Y and the length direction X are perpendicular to each other.

[0054] In some embodiments, the installation direction of the first annular butt edge 212 and the second annular butt edge 112 can be less than 5° with the length direction X.

[0055] As an example, the installation direction of the first annular butt edge 212 and the second annular butt edge 112 can be as shown in Figure 5 the direction indicated by the middle arrow B, and the installation direction B of the first annular butt edge 212 and the second annular butt edge 112 is less than 5° with the length direction X. Figure 5 indicated by the middle angle b. As an example, the installation direction B of the first annular butt edge 212 and the second annular butt edge 112 can be 1°, 2°, 2.5°, 3°, 4° or 4.5° or other numerical values.

[0056] By setting the installation direction B of the first annular butt edge 212 and the second annular butt edge 112 to be less than 5° with the length direction X, the contact area of the first annular butt edge 212 and the second annular butt edge 112 can be increased, and the interference between the second annular butt edge 112 and the core housing 210 during installation can be reduced, the consistency of assembly is affected, and the connection between the adapter housing 110 and the core housing 210 is more stable. Moreover, by setting the installation direction B of the first annular butt edge 212 and the second annular butt edge 112 to be more inclined to the length direction X, the bearing area 111 and the pressing area 211 can gradually apply pressing force to the terminal assembly 40, and the damage to the terminal assembly 40 caused by the direct impact of the pressing area 211 on the terminal assembly 40 can be reduced.

[0057] In some embodiments, the first annular butt edge 212 and the second annular butt edge 112 can be clamped by interference fit. In some embodiments, an adhesive medium can be filled between the opposite faces of the first annular butt edge 212 and the second annular butt edge 112 to enhance the stability of the connection between the two.

[0058] In some embodiments, such as Figure 5 to Figure 7 As shown, the second annular mating edge 112 may be provided with a flange 1121. The flange 1121 can engage with the first annular mating edge 212 along the thickness direction Z, so that the movement of the adapter housing 110 relative to the core housing 210 in the width direction Y, thickness direction Z and length direction X is restricted, thereby enhancing the connection strength between the first annular mating edge 212 and the second annular mating edge 112, further increasing the holding force applied to the terminal assembly 40 by the bearing area 111 and the holding area 211, making the installation of the terminal assembly 40 more secure, and improving the sealing performance of the earphone 1.

[0059] The shape of the flange 1121 provided on the second annular mating edge 112 can correspond to that of the first annular mating edge 212. In some embodiments, the flange 1121 can be annularly arranged, and the annular flange 1121 is provided on the side of the second annular mating edge 112 facing the interior of the movement housing 210. The first annular mating edge 212 abuts against the flange 1121 on the side of the flange 1121 facing the exterior of the adapter housing 110, thereby restricting the movement of the adapter housing 110 relative to the movement housing 210 in the width direction Y, thickness direction Z, and length direction X. This arrangement can increase the strength of the flange 1121 and reduce the possibility of the flange 1121 breaking during installation, which would affect the connection strength between the first annular mating edge 212 and the second annular mating edge 112.

[0060] In some embodiments, the movement housing 210 may be provided with a slot 2121 along the first annular mating edge 212. The shape of the slot 2121 may correspond to the flange 1121. When the first annular mating edge 212 and the second annular mating edge 112 are mated, a portion of the flange 1121 may extend into the slot 2121 and abut against the groove wall of the slot 2121. The shape of the slot 2121 further restricts the movement of the adapter housing 110 relative to the movement housing 210 in the positive directions of the width direction Y, the thickness direction Z, and the length direction X.

[0061] Specifically, during the assembly of the adapter housing 110 and the movement housing 210, a portion of the flange 1121 can extend into the slot 2121 along the mounting direction B, thereby limiting the flange 1121 by the first annular mating edge 212. In other words, the mounting direction B is the direction in which a portion of the flange 1121 can extend into the slot 2121 during the assembly of the adapter housing 110 and the movement housing 210.

[0062] In some embodiments, such as Figure 5 as well as Figure 6As shown, the flange 1121 is provided with a stopper 1122 on the side away from the free end 214, which abuts the inner wall surface of the core shell 210 in the length direction X. The stopper 1122 can be opposite the clamping groove 2121 in the length direction X, and the side of the stopper 1122 opposite the clamping groove 2121 abuts the inner wall surface of the core shell 210 in the length direction X, so that the clamping groove 2121 can limit the movement of the adapter shell 110 in the positive direction of the length direction X, and the core shell 210 can limit the movement of the adapter shell 110 in the negative direction of the length direction X by limiting the stopper 1122. As an example, the positive direction of the length direction X can be in the direction indicated by arrow D in the figure, and the negative direction of the length direction X can be in the direction indicated by arrow E in the figure.

[0063] In this way, the connection of the first annular abutting edge 212 and the second annular abutting edge 112 can be more closely connected, so that the adapter shell 110 and the core shell 210 are not prone to loosening relative to each other, thereby further improving the pressing force of the bearing area 111 and the pressing area 211 on the terminal assembly 40.

[0064] In some embodiments, as Figure 8 As shown, the core shell 210 can include a main bearing part 215 and an auxiliary connecting part 216. The pressing area 211 is located on the side of the auxiliary connecting part 216 facing the auricle 103 in the wearing state.

[0065] By arranging the pressing area 211 on the side of the auxiliary connecting part 216 facing the auricle 103 in the wearing state, and since the angle between the stacking direction C of the pressing area 211 and the thickness direction Z of the core shell 210 is not more than 5°, the terminal assembly 40 leaking out of the first through hole 1111 of the bearing area 111 in the wearing state can be blocked by the user, so that the terminal assembly 40 is not easily damaged by scratching, and the appearance of the earphone 1 can be improved.

[0066] The auxiliary connecting part 216 is partially arranged in an arc shape and connected to the main bearing part 215 at one end, and a spacing channel 201 is formed between the main bearing part 215 and the auxiliary connecting part 216. The second annular abutting edge 112 can be provided with a flange 1121, and the flange 1121 partially passes through the spacing channel 201 and is clamped with the first annular abutting edge 212.

[0067] In some embodiments, the flange 1121 can be provided with a stopper 1122, and the stopper 1122 passes through the spacing channel 201 and abuts against the inner wall surface of the movement housing 210 to be clamped with the first annular clamping edge 212. Specifically, during the assembly of the adapter housing 110 and the movement housing 210, part of the flange 1121 can extend into the clamping groove 2121 along the mounting direction B, and then the stopper 1122 can pass through the spacing channel 201 along the thickness direction Z to abut against the inner wall of the movement housing 210, so as to clamp the first annular clamping edge 212 and the second annular clamping edge 112.

[0068] In some embodiments, the main bearing part 215 and the auxiliary connecting part 216 can be integrally formed, which can enhance the connection firmness of the main bearing part 215 and the auxiliary connecting part 216 and improve the overall strength of the movement housing 210.

[0069] In some embodiments, as shown in Figure 5 and Figure 8 The auxiliary connecting part 216 can include a pressing area 211 and an arc-shaped area 2161. The pressing area 211 is in a flat plate shape, and one end of the pressing area 211 is connected to the main bearing part 215. One side of the arc-shaped area 2161 is connected to the pressing area 211, and the other side is curved and extends along the thickness direction Z towards the inside of the movement housing 210. The spacing channel 201 is formed between part of the first annular clamping edge 212 and the arc-shaped area 2161.

[0070] In some embodiments, as shown in Figure 6 The earphone 1 can include a speaker assembly 30 arranged in the movement housing 210 and close to the side of the auricle 103 in the wearing state, and a main control circuit board 50 arranged on the side of the speaker assembly 30 away from the auricle 103.

[0071] Further, the speaker assembly 30 can be arranged on the side of the auxiliary connecting part 216 away from the auricle 103, and part of the speaker assembly 30 can be placed on the side of the pressing area 211 away from the adapter housing 110. The arc-shaped area 2161 can be used to limit the movement of the speaker assembly 30 in the negative direction E of the length direction X, so as to limit the speaker assembly 30.

[0072] In some embodiments, as shown in Figure 6 The terminal assembly 40 is electrically connected to the main control circuit board 50 through the first wire 21, and the first wire 21 passes through the spacing channel 201.

[0073] The main control circuit board 50 refers to a control core part inside the earphone 1, and can be a PCB (Printed Circuit Board) circuit board or a FPC (Flexible Printed Circuit board) circuit board, etc. The main control circuit board 50 can be electrically connected with the speaker assembly 30 and the terminal assembly 40.

[0074] The first wire 21 can be a conductive wire, a flexible circuit board, or other structures or modules capable of transmitting current. The terminal assembly 40 is electrically connected with the main control circuit board 50 through the first wire 21. Specifically, one end of the first wire 21 can be connected with the terminal assembly 40, and the other end can extend into the inside of the core shell 210 through the spacing channel 201 and be connected with the main control circuit board 50. In this way, the line of the first wire 21 can be regularized through the spacing channel 201, so that the first wire 21 can be attached or abutted on the part of the arc-shaped wall of the auxiliary connecting part 216, i.e., the inner wall of the spacing channel 201, and extend, so that the first wire 21 is not excessively bent on the extension path and is not easy to be damaged, thereby prolonging the service life of the first wire 21, and also making the auxiliary connecting part 216 realize functional reuse.

[0075] In some embodiments, as shown in Figure 6 The speaker assembly 30 can include a main speaker 31 and an auxiliary speaker 32, and the auxiliary speaker 32 can be arranged between the auxiliary connecting part 216 and the main speaker 31, i.e., on the side of the main speaker 31 away from the main control circuit board 50. Figure 8 As shown in

[0076] The main speaker 31 and the auxiliary speaker 32 can be air-conduction speakers. The second wire 22 can be a conductive wire, a flexible circuit board, or other structures or modules capable of transmitting current. In this way, the auxiliary speaker 32 and the main control circuit board 50 can be remotely electrically connected, and the second wire 22 can extend along the wall surface of the core shell 210 and the auxiliary connecting part 216 by passing through the wire hole 2162 and the spacing channel 201, so that the auxiliary connecting part 216 and the core shell 210 can regularize the line of the second wire 22, so that the second wire 22 is not excessively bent on the extension path and is not easy to be damaged, and has a margin, so that it is not easy to be broken due to long vibration time of the auxiliary speaker 32, thereby ensuring the normal output of the auxiliary speaker 32 and improving the user's listening instructions.

[0077] In some embodiments, the wire hole 2162 can be arranged between the pressing area 211 and the arc-shaped area 2161. The position of the wire hole 2162 can be adapted to the position of the auxiliary speaker 32. One end of the second wire 22 is connected to the auxiliary speaker 32, and the other end of the second wire 22 passes through the wire hole 2162 along the wall of the pressing area 211 facing the inside of the core shell 210, and further passes through the spacing channel 201 to electrically connect the main control circuit board 50 located on the side of the main speaker 31 opposite to the auxiliary speaker 32.

[0078] In this way, the auxiliary speaker 32 and the main control circuit board 50 can be electrically connected, and the spacing channel 201 and the wire hole 2162 can regularize the second wire 22 and fix the second wire 22, so that the wiring inside the earphone 1 is more neat and regular.

[0079] In some embodiments, as shown in Figure 4 and Figure 6 The earphone 1 includes a battery assembly 60, which can be arranged in the ear hook 10. The battery assembly 60 is electrically connected to the main control circuit board 50 through a third wire 23, and the third wire 23 passes through the spacing channel 201.

[0080] The third wire 23 is a conductive wire, a flexible circuit board, or other structures or modules that can transmit current. One end of the third wire 23 can be connected to the battery assembly 60 in the ear hook 10, and the other end of the third wire 23 extends into the adapter shell 110 along the hook-shaped part 120 and passes through the spacing channel 201 to electrically connect the main control circuit board 50 in the core shell 210, so that the battery assembly 60 in the ear hook 10 can supply power to the elements in the sound production part 20 through the third wire 23.

[0081] Arranging the battery assembly 60 in the ear hook 10 can reduce the size of the sound production part 20 and improve the space utilization of the earphone 1. Moreover, arranging the third wire 23 to further extend into the inside of the core shell 210 along the hook-shaped part 120 and the spacing channel 201 to electrically connect the main control circuit board 50 can facilitate the electrical connection between the battery assembly 60 and the main control circuit board 50, reduce the redundancy of the third wire 23, and make the third wire 23 more regular.

[0082] In summary, the earphone 1 is provided with the pressing area 211 on the core shell 210 of the sound production part 20, the ear hook 10 is provided with the bearing area 111 on the adapter shell 110, and the terminal assembly 40 is arranged between the pressing area 211 and the bearing area 111. When the core shell 210 and the adapter shell 110 are connected, the terminal assembly 40 is clamped by the pressing area 211 and the bearing area 111 to be fixed in the earphone 1, and part of the terminal assembly 40 is exposed outside through the first through hole 1111 of the bearing area 111. In this way, on the one hand, the terminal assembly 40 can be stably arranged in the earphone 1 through the mutual clamping action of the pressing area 211 of the core shell 210 and the bearing area 111 of the adapter shell 110, without the need to additionally arrange a supporting structure to stabilize the terminal assembly 40, so as to simplify the structure inside the earphone 1, reduce the size of the earphone 1, and improve the space utilization and structural stability inside the earphone 1. At the same time, the mutual clamping action of the pressing area 211 and the bearing area 111 can also block the first through hole 1111, so as to reduce the risk of damage and corrosion of the elements inside the earphone 1 caused by the entry of impurities such as water and dust particles from the outside through the first through hole 1111.

[0083] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is based on the content of the specification and drawings, is also included in the patent protection scope of the present application.
