Description

earphone [Technical Field]

[0001] This application relates to the technical field of electronic devices, and in particular to headphones. [Background Technology]

[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 electronic devices are also getting higher and higher. Electronic devices such as headphones and smart glasses are also widely used in people's daily lives. They can be used in conjunction with terminal devices such as mobile phones and computers to provide users with an auditory feast.

[0003] Currently, Bluetooth earbuds typically need to be placed in a charging case, and the earbuds usually have exposed connection terminals that connect to the circuitry in the charging case, allowing the case to charge the earbuds. However, these connection terminals usually require a support structure for fixation, which takes up internal space and increases the size of the earbuds. Furthermore, external moisture, dust particles, and other impurities can easily enter the earbuds through the exposed connection terminals, damaging internal components.

[0004] [Summary of the Invention]

[0005] To address the aforementioned technical problems, this application provides a headphone comprising an ear hook and a sound-producing part connected to each other. In the wearing state, the ear hook is positioned between the user's ear and head, and the sound-producing part is located at the front of the ear. The sound-producing part includes a core housing, and the ear hook includes a connecting housing and a hook-shaped part. The connecting housing connects the core housing and the hook-shaped part. The headphone includes a terminal assembly. The core housing has a holding area, and the connecting housing has a supporting area. When the connecting housing and the core housing are connected, the supporting area and the holding area are stacked. The terminal assembly is positioned between the holding area and the supporting area and is held between them. A portion of the terminal assembly is exposed through a first through-hole in the supporting area.

[0006] In some embodiments, the bearing area is provided with a mounting groove, a first through hole is provided at the bottom of the mounting groove and penetrates the adapter housing, and the terminal assembly is pressed into the mounting groove by the pressing area.

[0007] In some embodiments, the terminal assembly includes a plurality of electrode terminals and a support plate. The plurality of electrode terminals are arranged in a spaced array on one side of the support plate and are electrically connected to a first trace through the support plate. The plurality of electrode terminals are connected to the main control circuit board in the movement housing through the first trace. The support plate is installed in a mounting groove. The number of first through holes corresponds to the number of electrode terminals. A portion of each electrode terminal is exposed through the corresponding first through hole.

[0008] In some embodiments, the housing of the mechanism has a thickness direction, which is the direction in which the sound-emitting part faces or away from the auricle when worn, and the angle between the stacking direction of the bearing area and the holding area and the thickness direction does not exceed 5°.

[0009] In some embodiments, the movement housing has a first annular mating edge, the adapter housing has a second annular mating edge, the first annular mating edge and the second annular mating edge abut against each other, and the projection of the bearing area and the holding area along the stacking direction falls inside the first annular mating edge and the second annular mating edge.

[0010] In some embodiments, the mechanism housing has a thickness direction, a width direction, and a length direction that are orthogonal to each other. The angle between the mounting direction of the first annular mating edge and the second annular mating edge and the length direction is less than 5°. The mechanism housing has a connecting end for connecting the ear hook and a free end disposed opposite to the connecting end. The length direction is the direction in which the free end and the connecting end are spaced apart. The thickness direction is the direction in which the sound-emitting part faces or moves away from the auricle when worn.

[0011] In some embodiments, the second annular mating edge is provided with a flange, which engages with the first annular mating edge along the thickness direction, thereby restricting the movement of the adapter housing relative to the core housing in the width, thickness, and length directions.

[0012] In some embodiments, the movement housing is provided with a groove along the first annular mating edge, a portion of the flange extends into the groove and abuts against the groove wall, the shape of the groove is configured such that the movement of the adapter housing relative to the movement housing in the positive directions of the width direction, thickness direction and length direction is restricted, and a stop block is provided on the side of the flange away from the free end, the stop block abuts against the inner wall surface of the movement housing in the length direction.

[0013] In some embodiments, the mechanism housing includes a main support portion and an auxiliary connection portion. The holding area is located on the side of the auxiliary connection portion facing the auricle when worn. The auxiliary connection portion is arc-shaped and its two ends are connected to the main support portion. A spaced channel is formed between the main support portion and the auxiliary connection portion. A flange is provided on the second annular mating edge. The flange portion passes through the spaced channel and engages with the first annular mating edge.

[0014] In some embodiments, the earphone includes a speaker assembly disposed within the housing and close to the auricle when worn, and a main control circuit board disposed on the side of the speaker assembly away from the auricle.

[0016] In some embodiments, the headphones include a battery assembly disposed in the ear hook, and the battery assembly is electrically connected to the main control circuit board via a third trace passing through a spacer channel.

[0017] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a holding area on the core housing of the headphone's sound-producing section, a carrying area on the adapter housing of the ear hook, and a terminal assembly positioned between the holding area and the carrying area. When the core housing and the adapter housing are connected, the terminal assembly can be clamped and fixed inside the headphone by the holding area and the carrying area, with a portion of the terminal assembly exposed through a first through-hole in the carrying area. This design allows the terminal assembly to be securely held inside the headphone solely by the mutual clamping action of the holding area of ​​the core housing and the carrying area of ​​the adapter housing, eliminating the need for additional support structures. This simplifies the internal structure of the headphone, reduces its size, and improves internal space utilization and structural stability. Simultaneously, the mutual clamping action of the holding area and the carrying area also seals the first through-hole, reducing the entry of external moisture, dust particles, and other impurities into the headphone through this opening, thus lowering the risk of damage or corrosion to internal components.

Detailed Implementation Methods

[0026] 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.

[0027] 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.

[0028] The following is an exemplary description of the headphones in the example embodiment.

[0029] Referring to Figure 1, the user's ear 100 may include physiological parts such as the external auditory canal 101, the concha 102, and the auricle 103. While the external auditory canal 101 has a certain depth and extends to the tympanic membrane of the ear 100, for ease of description, unless otherwise specified, the external auditory canal 101 specifically refers to its entrance (i.e., ear canal) away from the tympanic membrane. Furthermore, the concha 102 has a certain volume and depth, and is directly connected to the external auditory canal 101; that is, the aforementioned ear canal can be simply considered as being located at the bottom of the concha 102.

[0030] Headphone 1 is an audio converter capable of receiving electrical signals from a media player or receiver and converting them into sound waves that can be heard by the user. In some embodiments, headphone 1 can be an open-back headphone, such as an ear-hook headphone, a behind-the-ear headphone, or a clip-on headphone.

[0031] As shown in Figure 2 or Figure 3, the earphone 1 can be an ear-hook type earphone. In some embodiments, when worn, at least a portion of the earphone 1 can be inserted into the concha 102 of the user to improve wearing stability. In some embodiments, the sound-emitting part of the earphone 1 can at least partially cover the auricle 103 of the user's ear, such as the antihelix, cymba concha, or triangular fossa (not shown in the figure), but does not block the external auditory canal 101 of the user's ear or visually obscure the external auditory canal 101 of the user's ear. In some embodiments, the sound-emitting part 20 of the earphone 1 can also fit against or rest against the facial area in front of the user's ear, with the side of the sound-emitting part 20 facing the user's ear or the user's external auditory canal 101.

[0032] Furthermore, individual differences may exist among different users, resulting in variations in the shape, size, and other dimensions of the earpiece 100. To facilitate description and reduce (or even eliminate) these individual differences, a simulator containing a head and its (left and right) earpieces 100 can be manufactured based on ANSI:S3.36, S3.25 and IEC:60318-7 standards. Examples include the GRAS 45BC KEMAR, HEAD Acoustics, B&K 4128 series, or B&K 5128 series, to represent the scenario of most users wearing the headphones 1. Taking the GRAS KEMAR as an example, the simulator for the earpiece 100 can be any one of the GRAS 45AC, GRAS 45BC, GRAS 45CC, or GRAS 43AG; taking HEAD Acoustics as an example, the simulator for the earpiece 100 can be any one of the HMS II.3, HMS II.3LN, or HMS II.3LN HEC. Therefore, in this application, descriptions such as "the user is wearing earphone 1," "earphone 1 is in a wearing state," and "in a wearing state" can refer to the earphone 1 being worn on the ear 100 of the aforementioned simulator. Of course, due to individual differences among users, the earphone 1 worn by different users may differ from the earphone 1 being worn on the ear 100 of the aforementioned simulator, but such differences should be tolerable.

[0033] It should be noted that in fields such as medicine and anatomy, 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—can be defined for the human body or human simulator. The sagittal plane is a plane perpendicular to the ground along the anteroposterior direction of the body, dividing the human body or human simulator into left and right parts. The coronal plane is a plane perpendicular to the ground along the left and right direction of the body, dividing the human body or human simulator into anterior and posterior parts. The horizontal plane is a plane parallel to the ground along the vertical direction of the body, dividing the human body or human simulator 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 and 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 "front side of the ear" mentioned in this application is a concept relative to "back side of the ear." The former refers to the side of the ear that is away from the head, while the latter refers to the side of the ear that faces the head. Both refer to the ear 100 of the user or simulator. The ear 100 of the human body or human simulator viewed along the coronal axis can be shown in Figure 1.

[0034] As an example, referring to Figures 2 and 3, the earphone 1 may include an ear hook 10 and a sound-emitting part 20 connected to each other. In the wearing state, the ear hook 10 can be positioned between the user's auricle 103 and head, that is, at least a portion of the ear hook 10 of the earphone 1 can be located behind the ear 100, so that the earphone 1 is attached to the ear 100, and the sound-emitting part 20 can be located in front of the auricle 103. The sound-emitting part 20 can be a sound playback device, which can be used to convert electrical signals into sound signals (also referred to as "sound waves" or "sound signals") and propagate them to the wearer's ear 100.

[0035] In some embodiments, the ear hook 10 may contain a battery or a circuit board, or the ear hook 10 may contain both a battery and a circuit board. Of course, the ear hook 10 may also omit the battery and circuit board, and instead install the battery and circuit board into the sound-generating part 20.

[0036] In some embodiments, as shown in Figures 2 and 3, the sound-emitting part 20 may include a mechanism housing 210. In some embodiments, the earphone 1 may also include a speaker assembly 30 disposed within the mechanism housing 210. The speaker assembly 30 is a component that can convert electrical signals into corresponding sound signals to realize the sound playback function of the sound-emitting part 20. As an example, the speaker assembly 30 may include a bone conduction speaker and an air conduction speaker; in other embodiments, the speaker assembly 30 may also be configured as one of an air conduction speaker and a bone conduction speaker.

[0037] In some embodiments, as shown in Figures 2 and 3, the ear hook 10 may include an adapter housing 110 and a hook portion 120, the adapter housing 110 being used to connect the mechanism housing 210 and the hook portion 120. The hook portion 120 may be hook-shaped so that it can be hooked onto the user's ear 100 when the user is wearing the earphone 1.

[0038] In some embodiments, as shown in Figures 4 to 7, the earphone 1 may include a terminal assembly 40 and a main control circuit board 50. The core housing 210 has a holding area 211, and the adapter housing 110 has a carrying area 111. When the adapter housing 110 and the core housing 210 are connected to each other, the carrying area 111 and the holding area 211 are stacked. The terminal assembly 40 is disposed between the holding area 211 and the carrying area 111 and is held by the holding area 211 and the carrying area 111. A portion of the terminal assembly 40 is exposed through the first through hole 1111 of the carrying area 111.

[0039] The terminal assembly 40 includes electrode terminals 41. A portion of the electrode terminals 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 portion is electrically connected to the main control circuit board 50, so that the earphone 1 can be electrically connected to the internal circuit of the charging case through the terminal assembly 40, thereby enabling the charging case to charge the earphone 1 through the terminal assembly 40.

[0040] In some embodiments, the terminal assembly 40 may further include a detection terminal (not shown in the figure), which facilitates the earphone 1 to perform detection functions such as charging detection and detection of the earphone 1 being placed in or removed from the charging case.

[0041] Specifically, when the mechanism housing 210 is connected to the adapter housing 110, the terminal assembly 40 is clamped and fixed inside the earphone 1 by the holding area 211 and the bearing area 111, and part of the terminal assembly 40 is exposed through the first through hole 1111 of the bearing area 111. This arrangement allows the terminal assembly 40 to be securely held inside the earphone 1 solely by the mutual clamping action of the holding area 211 of the mechanism housing 210 and the bearing area 111 of the adapter housing 110, eliminating the need for additional support structures. This simplifies the internal structure of the earphone 1, reduces assembly difficulty, decreases size, and improves internal space utilization and structural stability. Simultaneously, the terminal assembly 40 can seal the first through hole 1111 under the action of the holding area 211 and the bearing area 111, thereby reducing the risk of damage or corrosion to internal components through the first through hole 1111.

[0042] In some embodiments, as shown in FIG4, the bearing area 111 may be provided with a mounting groove 1112, and a first through hole 1111 is provided at the bottom of the mounting groove 1112 and penetrates the adapter housing 110. The terminal assembly 40 can be pressed into the mounting groove 1112 by the pressing area 211. With this configuration, the mounting groove 1112 can be used to limit the terminal assembly 40, thereby further limiting the degree of freedom of the fixed terminal assembly 40 except for the pressing direction, 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.

[0043] In some embodiments, as shown in FIG4, the terminal assembly 40 may include a plurality of electrode terminals 41 and a support plate 42. The plurality of electrode terminals 41 may be arranged in a spaced array on one side of the support plate 42 and electrically connected to a first trace 21 via the support plate 42. The plurality of electrode terminals 41 are also connected to the main control circuit board 50 in the mechanism housing 210 via the first trace 21. The first trace 21 may be a flexible circuit board, a wire, or other structure or module capable of transmitting current. The number of first through holes 1111 corresponds to the number of electrode terminals 41, with a portion of each electrode terminal 41 exposed through a corresponding first through hole 1111. By fixing the plurality of electrode terminals 41 using the support plate 42, the plurality of electrode terminals 41 can be arranged in a regular, aligned manner, ensuring consistency and stability of the electrical connection. The support plate 42 may be entirely constructed of conductive metal or plastic material, or it may be partially constructed of conductive metal material and partially constructed of non-conductive plastic material.

[0044] Specifically, the support plate 42 is installed in the mounting groove 1112. The shape of the mounting groove 1112 and the position and 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.

[0045] The housing 210 may have a thickness direction, which is the direction in which the sound-emitting part 20 of the housing 210 faces or moves away from the auricle 103 when the housing is worn. The angle between the stacking direction of the bearing area 111 and the holding area 211 and the thickness direction does not exceed 5°.

[0046] As an example, the stacking direction of the bearing region 111 and the pressing region 211 can be as shown by arrow C in Figure 7, and the thickness direction can be as shown by arrow Z in Figure 7. As an example, the angle between the stacking direction C of the bearing region 111 and the pressing region 211 and the thickness direction Z can be 0°, 1°, 2.5°, 4°, or 4.5°, etc.

[0047] If the angle between the stacking direction C of the bearing area 111 and the pressing area 211 and the thickness direction Z is set to exceed 5°, the bearing area 111, the pressing area 211, and the terminal assembly 40 will occupy a large space in the thickness direction Z. Moreover, the excessive tilt of the stacking direction C of the bearing area 111 and the pressing area 211 relative to the thickness direction Z will also increase the lateral force on the terminal assembly 40, increase the installation difficulty of the terminal assembly 40, and affect the service life of the terminal assembly 40.

[0048] Therefore, by setting the angle between the stacking direction C of the bearing area 111 and the pressing area 211 and the thickness direction Z to no more than 5°, it is possible not only to reduce the space occupied by the bearing area 111, the pressing area 211 and the terminal assembly 40 in the thickness direction Z, and to reduce the size of the earphone 1 in the thickness direction Z, but also to reduce the installation difficulty of the terminal assembly 40.

[0049] In some embodiments, as shown in Figures 4 to 7, the movement housing 210 has a first annular mating edge 212, and the adapter housing 110 has a second annular mating edge 112. When the movement housing 210 and the adapter housing 110 are connected, the first annular mating edge 212 and the second annular mating edge 112 can mate with each other. The projections of the bearing area 111 and the pressing area 211 along the stacking direction can fall inside the first annular mating edge 212 and the second annular mating edge 112.

[0050] Specifically, the first annular mating edge 212 and the second annular mating edge 112 can present an irregular annular structure. The core housing 210 and the adapter housing 110 can be mated and fixed together through the annular first annular mating edge 212 and the second annular mating edge 112. This arrangement simplifies the connection and fixing structure between the core housing 210 and the adapter housing 110, and the annular mating structure also makes the connection between the ear hook 10 and the sound-emitting part 20 more stable, thereby improving the structural stability of the earphone 1.

[0051] Furthermore, since the first annular mating edge 212 and the second annular mating edge 112 abut against each other, the bearing area 111 and the pressing area 211 also press against each other in the stacking direction. Therefore, the pressure generated by the abutment of the first annular mating edge 212 and the second annular mating edge 112 will affect the stacking pressing 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 inside the first annular mating edge 212 and the second annular mating edge 112. This can strengthen the pressing force of the bearing area 111 and the pressing area 211 against each other in the stacking direction C, thereby enabling the bearing area 111 and the pressing area 211 to strengthen the clamping force on the terminal assembly 40, making the terminal assembly 40 more stable, thereby improving the tightness and stability of the internal structure of the earphone 1.

[0052] In some embodiments, as shown in Figures 2 and 3, the mechanism housing 210 may have thickness, width, and length directions that are orthogonal to each other. The mechanism housing 210 has a connecting end 213 for connecting the ear hook 10 and a free end 214 disposed opposite to the connecting end 213. In the wearing state, at least a portion of the free end 214 may extend into the concha 102 or abut against the user's auricle 103.

[0053] The length direction can be the spacing direction between the connecting end 213 and the free end 214. The spacing direction between the connecting end 213 and the free end 214 refers to the direction of extension of the line connecting the connecting end 213 and the free end 214. In some embodiments, the connecting end 213 and the free end 214 can be irregular or regular arc-shaped, and the direction of extension of the line connecting the connecting end 213 and the free end 214 can be defined by a straight line perpendicular to the parallel tangent plane of the two reference points furthest apart on the connecting end 213 and the free end 214. The length direction can also be defined as the direction in which the movement housing 210 approaches or moves away from the back of the head when worn, that is, the direction defined between the side of the movement housing 210 that approaches the back of the head and the side that moves away from the back of the head when worn. As an example, the length direction can be the direction shown by arrow X in Figures 2 to 7. It should be noted that the length, width, and thickness directions of the movement housing 210 defined in this specification using the wearing state are all based on the movement housing 210 and are independent of the three basic axes of the human body, and will not change due to slight differences when worn on the ears of different users.

[0054] The width direction can be defined as the direction in which the movement housing 210 approaches or moves away from the top of the head when worn, that is, the direction defined between the side of the movement housing 210 that approaches the top of the head and the side that moves away from the top of the head when worn. As an example, the width direction can be the direction indicated by arrow Y in Figures 2 to 7. In this case, the thickness direction Z, the width direction Y, and the length direction X are all perpendicular to each other.

[0055] In some embodiments, the angle between the mounting direction of the first annular mating edge 212 and the second annular mating edge 112 and the length direction X can be less than 5°.

[0056] As an example, the mounting direction of the first annular mating edge 212 and the second annular mating edge 112 can be as shown by arrow B in Figure 5, and the angle between the mounting direction B of the first annular mating edge 212 and the second annular mating edge 112 and the length direction X is shown by angle b in Figure 5. As an example, the angle between the mounting direction B of the first annular mating edge 212 and the second annular mating edge 112 and the length direction X can be other values ​​such as 1°, 2°, 2.5°, 3°, 4° or 4.5°.

[0057] Setting the angle between the mounting direction B of the first annular mating edge 212 and the second annular mating edge 112 and the length direction X to less than 5° can increase the contact area of ​​the first annular mating edge 212 and the second annular mating edge 112, reduce the interference between the second annular mating edge 112 and the core housing 210 during installation, and improve the consistency of assembly, making the connection between the adapter housing 110 and the core housing 210 more stable. Furthermore, setting the mounting direction B of the first annular mating edge 212 and the second annular mating edge 112 to be more biased towards the length direction X allows the bearing area 111 and the holding area 211 to gradually apply holding force to the terminal assembly 40, reducing the possibility of the holding area 211 directly impacting the terminal assembly 40 and causing damage.

[0058] In some embodiments, the first annular mating edge 212 and the second annular mating edge 112 can be interlocked by an interference fit. In some embodiments, an adhesive medium can be filled between the opposing surfaces of the first annular mating edge 212 and the second annular mating edge 112 to enhance the stability of their connection.

[0059] In some embodiments, as shown in Figures 5 to 7, 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, thereby restricting 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. This enhances the connection strength between the first annular mating edge 212 and the second annular mating edge 112, further increasing the holding force exerted by the bearing area 111 and the holding area 211 on the terminal assembly 40, making the installation of the terminal assembly 40 more secure, and improving the sealing performance of the earphone 1.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] In some embodiments, as shown in Figures 5 and 6, a stop block 1122 is provided on the side of the flange 1121 away from the free end 214. The stop block 1122 abuts against the inner wall surface of the movement housing 210 along the length direction X. The stop block 1122 may be opposite to the slot 2121 in the length direction X, and the side of the stop block 1122 facing away from the slot 2121 abuts against the inner wall surface of the movement housing 210 in the length direction X. This allows the slot 2121 to restrict the movement of the adapter housing 110 in the positive direction of the length direction X, and the movement housing 210 can restrict the movement of the adapter housing 110 in the negative direction of the length direction X by limiting the stop block 1122. As an example, the positive direction of the length direction X can be the direction shown by arrow D in the figure, and the negative direction of the length direction X can be the direction shown by arrow E in the figure.

[0064] With this configuration, the connection between the first annular mating edge 212 and the second annular mating edge 112 can be tighter, making it less likely for the adapter housing 110 and the core housing 210 to become loose relative to each other, thereby further increasing the holding force applied by the bearing area 111 and the holding area 211 to the terminal assembly 40.

[0065] In some embodiments, as shown in FIG8, the mechanism housing 210 may include a main support portion 215 and an auxiliary connection portion 216. The holding area 211 is located on the side of the auxiliary connection portion 216 facing the auricle 103 when worn.

[0066] The holding area 211 is set on the side of the auxiliary connection part 216 facing the auricle 103 when worn. Since the angle between the stacking direction C of the holding area 211 and the bearing area 111 and the thickness direction Z of the core housing 210 does not exceed 5°, the terminal assembly 40 exposed on the first through hole 1111 of the bearing area 111 can be covered by the user when worn, so that the terminal assembly 40 is not easily scratched or damaged, and the aesthetics of the earphone 1 can also be improved.

[0067] The auxiliary connecting part 216 is partially arc-shaped and one end is connected to the main bearing part 215, forming a gap channel 201 between the main bearing part 215 and the auxiliary connecting part 216. The second annular mating edge 112 may be provided with a flange 1121, and part of the flange 1121 passes through the gap channel 201 and engages with the first annular mating edge 212.

[0068] In some embodiments, a stop block 1122 may be provided on the flange 1121, and the stop block 1122 passes through the spacer channel 201 and abuts against the inner wall surface of the movement housing 210, engaging with the first annular mating edge 212. Specifically, during the assembly of the adapter housing 110 and the movement housing 210, after a portion of the flange 1121 can extend into the slot 2121 along the installation direction B, the stop block 1122 can pass through the spacer channel 201 along the thickness direction Z to abut against the inner wall of the movement housing 210, thereby achieving engagement between the first annular mating edge 212 and the second annular mating edge 112.

[0069] In some embodiments, the main support portion 215 and the auxiliary connecting portion 216 may be integrally formed, which can strengthen the connection between the main support portion 215 and the auxiliary connecting portion 216 and improve the overall strength of the movement housing 210.

[0070] In some embodiments, as shown in Figures 5 and 8, the auxiliary connecting portion 216 may include a pressing area 211 and an arc-shaped area 2161. The pressing area 211 is flat, and one end of the pressing area 211 is connected to the main bearing portion 215. One side of the arc-shaped area 2161 is connected to the pressing area 211, and the other side extends inward along the thickness direction Z toward the interior of the movement housing 210. A spacer channel 201 is formed between a portion of the first annular mating edge 212 and the arc-shaped area 2161.

[0071] In some embodiments, as shown in FIG6, the earphone 1 may include a speaker assembly 30 disposed within the housing 210 and on the side closer to the auricle 103 when worn, and a main control circuit board 50 disposed on the side of the speaker assembly 30 away from the auricle 103.

[0072] Furthermore, the speaker assembly 30 can be disposed on the side of the auxiliary connection portion 216 away from the auricle 103, and a portion of the speaker assembly 30 can be placed on the side of the holding area 211 away from the adapter housing 110. The arc-shaped area 2161 can be used to restrict the speaker assembly 30 from moving in the negative direction E of the length direction X, thereby achieving the limitation of the speaker assembly 30.

[0073] In some embodiments, as shown in FIG6, the terminal assembly 40 is electrically connected to the main control circuit board 50 via a first trace 21, which passes through the spacer channel 201.

[0074] The main control circuit board 50 refers to the core control component inside the earphone 1. The main control circuit board 50 can be a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit Board), etc. The main control circuit board 50 can electrically connect to the speaker assembly 30 and the terminal assembly 40.

[0075] The first trace 21 can be a conductive wire, a flexible circuit board, or other structure or module capable of transmitting current. The terminal assembly 40 is electrically connected to the main control circuit board 50 through the first trace 21. Specifically, one end of the first trace 21 can be connected to the terminal assembly 40, and the other end can extend through the spacer channel 201 into the interior of the mechanism housing 210 and connect to the main control circuit board 50. This arrangement allows the spacer channel 201 to organize the path of the first trace 21, enabling the first trace 21 to conform to or abut against the inner wall of the spacer channel 201, i.e., part of the arc-shaped wall of the auxiliary connection part 216, and extend there. This prevents the first trace 21 from being excessively bent or damaged during its extension path, thus extending its service life and enabling the auxiliary connection part 216 to achieve functional reuse.

[0076] In some embodiments, as shown in FIG6, the speaker assembly 30 may include a main speaker 31 and an auxiliary speaker 32. The auxiliary speaker 32 may be disposed between the auxiliary connection portion 216 and the main speaker 31, that is, on the side of the main speaker 31 facing away from the main control circuit board 50. As shown in FIG8, the auxiliary connection portion 216 is provided with a wiring hole 2162. The auxiliary speaker 32 is electrically connected to the main control circuit board 50 via a second wiring 22, which passes through the wiring hole 2162 and the spacing channel 201.

[0077] The main speaker 31 and auxiliary speaker 32 can be air-conducting speakers. The second wiring 22 can be a conductive wire, a flexible circuit board, or other structures or modules capable of transmitting current. This configuration facilitates long-distance electrical connection between the auxiliary speaker 32 and the main control circuit board 50. By passing the second wiring 22 through the wiring hole 2162 and the spacer channel 201, the second wiring 22 can extend along the walls of the housing 210 and the auxiliary connection part 216. This allows the auxiliary connection part 216 and the housing 210 to organize the wiring of the second wiring 22, ensuring that the second wiring 22 is not excessively bent or damaged along its extension path, and that it has sufficient slack to prevent breakage due to prolonged vibration of the auxiliary speaker 32. This, in turn, ensures the normal output of the auxiliary speaker 32 and enhances the user's listening experience.

[0078] In some embodiments, the wiring hole 2162 may be correspondingly disposed between the holding area 211 and the arc-shaped area 2161. The position of the wiring hole 2162 may be adapted to the position of the auxiliary speaker 32. One end of the second wiring 22 is connected to the auxiliary speaker 32, and the other end passes through the wiring hole 2162 along the wall of the holding area 211 facing the inside of the housing 210, and further passes through the spacer channel 201 to electrically connect to the main control circuit board 50 located on the side of the main speaker 31 facing away from the auxiliary speaker 32.

[0079] This configuration facilitates the electrical connection between the auxiliary speaker 32 and the main control circuit board 50. It also allows the spacer channel 201 and the wiring hole 2162 to organize the wiring of the second wiring 22 and fix the second wiring 22, making the wiring inside the headphone 1 neater and more organized.

[0080] In some embodiments, as shown in Figures 4 and 6, the earphone 1 includes a battery assembly 60, which may be disposed in the ear hook 10. The battery assembly 60 is electrically connected to the main control circuit board 50 via a third trace 23, which passes through the spacer channel 201.

[0081] The third trace 23 is a conductive wire, a flexible circuit board, or other structure or module capable of transmitting current. One end of the third trace 23 can be connected to the battery assembly 60 in the ear hook 10, and the other end of the third trace 23 extends along the hook-shaped portion 120 into the adapter housing 110, and passes through the spacer channel 201 to be electrically connected to the main control circuit board 50 in the mechanism housing 210, so that the battery assembly 60 in the ear hook 10 can supply power to the components in the sound-generating part 20 through the third trace 23.

[0082] By placing the battery assembly 60 in the ear hook 10, the size of the sound-generating part 20 can be reduced, improving the space utilization of the earphone 1. Furthermore, the third wiring 23 extends further into the interior of the mechanism housing 210 along the hook-shaped part 120 and the spacer channel 201 to electrically connect to the main control circuit board 50, so that the battery assembly 60 and the main control circuit board 50 can be electrically connected, reducing the redundancy of the third wiring 23 and making the third wiring 23 more organized.

[0083] In summary, this application provides a holding area 211 on the housing 210 of the sound-producing part 20 of the earphone 1, a carrying area 111 on the adapter housing 110 of the ear hook 10, and a terminal assembly 40 disposed between the holding area 211 and the carrying area 111. When the housing 210 and the adapter housing 110 are connected, the terminal assembly 40 is clamped and fixed inside the earphone 1 by the holding area 211 and the carrying area 111, and a portion of the terminal assembly 40 is exposed through the first through hole 1111 of the carrying area 111. This arrangement allows the terminal assembly 40 to be securely fixed inside the earphone 1 solely through the clamping action of the holding area 211 of the housing 210 and the carrying area 111 of the adapter housing 110, eliminating the need for additional support structures. This simplifies the internal structure of the earphone 1, reduces its size, and improves the space utilization and structural stability of the earphone 1. At the same time, the mutual clamping effect between the holding area 211 and the bearing area 111 can also allow the terminal assembly 40 to block the first through hole 1111, thereby reducing the possibility of external moisture, dust particles and other impurities entering the earphone 1 through the first through hole 1111, thus reducing the risk of damage and corrosion to the components inside the earphone 1.

[0084] The above description is merely an embodiment of this application and does not limit the patent scope of this application. 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.
