Thus, on the one hand, the second contact surface can abut against the antihelix, allowing the earphone to be stably placed within the concha and preventing it from easily falling out. On the other hand, the first elastic member is configured to drive the fixing part away from the main body, further increasing the pressure exerted by the fixing part on the antihelix. Furthermore, the first elastic member provides elasticity, allowing the fixing arm to extend to different angles, helping the fixing part adapt to different sizes of concha, thereby improving the earphone's adaptability and wearing comfort.

Description

Technical Field

[0001] This utility model relates to the field of electroacoustic conversion technology, and in particular to an earphone. Background Technology

[0002] In-ear headphones, with their sound outlet directly facing the ear canal, provide a better sound quality experience, and the ear tips reduce the impact of ambient noise. However, in-ear headphones are prone to falling out, especially during exercise, where the risk increases significantly. This necessitates constant securing of the headphones, impacting the user experience. Therefore, reducing the risk of headphones falling out is a problem that needs to be addressed. Utility Model Content

[0003] In view of this, the present invention provides an earphone in which the fixing part is rotatably connected to the main body. When the first contact surface is in contact with the concha cavity, the fixing part can be unfolded and abut against the antihelix, so as to fix the main body through the fixing part and reduce the risk of the earphone falling off during use.

[0004] An embodiment of the present invention provides an earphone, the earphone comprising:

[0005] The body includes a first contact surface; and

[0006] The fixing part includes a fixing arm and a first elastic element. The fixing arm has a second contact surface, a free end and a connecting end. The connecting end is rotatably connected to the body. The first elastic element is configured to drive the free end to rotate away from the body.

[0007] In the direction away from the first contact surface of the earphone, the second contact surface extends from the connecting end to the free end in a preset direction, and the second contact surface is opposite to the body and bends away from the body.

[0008] Furthermore, the fixed arm includes a connector and an elastic contact member. The elastic contact member has a second contact surface and a free end. The connector is disposed on the side of the elastic contact member opposite to the second contact surface, and the connecting end is disposed at one end of the connector.

[0009] Furthermore, the free end has an arc surface;

[0010] The free end extends toward the side of the connector away from the connecting end, and the arc surface bends toward the side away from the connecting end.

[0011] Furthermore, the elastic contact element is configured as an elastic rod, and the free end is disposed at one end of the elastic rod;

[0012] The connector includes a fixed beam, at least a portion of which is disposed inside the elastic rod and both the fixed beam and the elastic rod are bent away from the body. The connecting end is disposed at one end of the fixed beam and is located on the side of the fixed beam away from the elastic rod.

[0013] Furthermore, the headphones also include:

[0014] A locking part is provided on the body, and the free end is in a retracted state close to the body. The locking part is unclampedly connected to the fixed arm.

[0015] The body includes an earphone shell, which has the sound outlet, the first contact surface, and a connection hole, with the connection hole located on the side of the earphone shell opposite to the first contact surface.

[0016] The locking part has a driving member and a second elastic member. The driving member includes an operating handle that extends from the connecting hole. The driving member is axially movable along the connecting hole. The driving member abuts against the second elastic member. The second elastic member is configured to drive the driving member to move outward from the earphone shell. The driving member has a first position and a second position in the moving direction.

[0017] In the first position, the locking part is connected to the connector; in the second position, the locking part releases the connector.

[0018] Furthermore, the locking part also includes:

[0020] A limiting body is disposed on the driving member and includes two limiting rods corresponding to the two elastic arms;

[0021] The connector has a slot with an opening and two limiting surfaces. The opening faces the body, and the two limiting surfaces are formed on the inner wall of the slot and located on both sides of the opening. The orientation of the two limiting surfaces is opposite to the orientation of the opening.

[0022] In the first position, the two curved ends extend into the slot through the opening and abut against the two limiting surfaces. From the first position to the second position, the two limiting rods press the two elastic arms closer to each other, and the two curved ends separate from the two limiting surfaces and move to the opening.

[0023] Furthermore, the bent end has a mating surface facing the fixed arm;

[0024] The slot also has two guide ramps corresponding to the two mating surfaces respectively, the openings are formed on the opposite sides of the two guide ramps, and the opposite sides of the two guide ramps extend toward the bottom of the slot and bend in opposite directions.

[0025] Furthermore, the limiting rod includes a curved section and a straight section, the straight section extending axially along the connecting hole, one end of the curved section being connected to the straight section, and the other end bending toward the opposite sides of the two curved sections;

[0026] In the first position, the two straight segments are located on both sides of the two elastic arms. From the first position to the second position, the two curved segments respectively abut against the two elastic arms and drive the two elastic arms to move closer to each other.

[0027] Furthermore, the third elastic element also includes a deformation section, which bends away from the slot to form a clearance space. The two elastic arms are connected to the two ends of the deformation section, and the deformation section generates an elastic force that drives the two elastic arms away from each other.

[0028] The drive unit also includes a first connecting handle, one end of which is connected to the operating handle, and the other end passes through the clearance space and abuts against the second elastic member.

[0029] Furthermore, the fixed arm also includes a first magnetic body, which is disposed on the connector;

[0030] The driving component further includes a second connecting handle and a second magnetic body. The second connecting handle has a first fixing groove facing the fixing arm, and the second magnetic body is disposed in the first fixing groove.

[0031] In the first position, with the fixed arm close to the body, the first magnetic body and the second magnetic body are positioned opposite each other and attracted together; in the second position, the first magnetic body and the second magnetic body are offset.

[0032] Furthermore, the second connecting handle also has a second fixing groove, which is oriented in the same direction as the first fixing groove and is spaced apart along the axial direction of the second connecting handle;

[0033] The driving component further includes a third magnetic body, which is disposed in the second fixing groove, and the third magnetic body has the same polarity as the first magnetic body.

[0034] The fixed arm is positioned close to the body, and in the second position, the third magnet is opposite to the first magnet.

[0035] Furthermore, the body also includes a sound outlet;

[0036] In the direction away from the first contact surface of the earphone, the sound outlet is located on the side of the body away from the connection end, and the sound outlet is inclined relative to the reference line along the preset direction.

[0037] The body has a first receiving groove;

[0038] The connecting end is rotatably disposed in the first receiving groove, and the connecting end has a receiving hole;

[0039] The first elastic element is a torsion spring, which includes a coil body and two drive arms connected to the coil body;

[0040] The ring body is disposed in the receiving hole, one of the driving arms is connected to the connecting end, and the other driving arm extends out of the receiving hole and is connected to the body.

[0041] In this embodiment of the earphone, the connecting end of the fixing part is rotatably connected to the main body, and the second contact surface is located on the side away from the main body and bent in a direction away from the main body. Therefore, on the one hand, the second contact surface can abut against the antihelix, allowing the earphone to be stably placed within the concha and preventing it from easily falling out. On the other hand, the first elastic member is configured to drive the fixing part away from the main body, further increasing the pressure exerted by the fixing part on the antihelix. Furthermore, the first elastic member provides elasticity, allowing the fixing arm to extend to different angles, helping the fixing part adapt to different sizes of concha, thereby improving the earphone's adaptability and wearing comfort.

[0072] The present invention will now be described based on embodiments, but it is not limited to these embodiments. In the following detailed description of the present invention, certain specific details are described in detail. Those skilled in the art will fully understand the present invention even without these details. To avoid obscuring the essence of the present invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0073] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0074] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0075] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0076] Unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0077] For ease of explanation, spatially related terms such as “inside,” “outside,” “below,” “below,” “lower,” “above,” “upper,” etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or operation besides those depicted in the figure. For example, if the device in the figure is flipped, an element described as “below” or “below” another element or feature would then be positioned “above” that other element or feature. Thus, the exemplified term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly.

[0078] Figure 1 , Figure 2 and Figure 3 This is a schematic diagram of the headphone structure in this embodiment. Figure 1 The fixing part 1 is in a retracted state close to the main body 2. Figure 2 The fixed part 1 is in an unfolded state, away from the main body 2. Figure 3 The reference line I is shown in dashed lines, as well as the center point Ia, which is approximately located at the center of the first contact surface 22 and passes through the center point Ia.

[0079] In some implementations, such as Figures 1-2 As shown, the earphone in this embodiment includes a fixing part 1, a body 2, and a locking part 3. The fixing part 1 is rotatably connected to the body 2, and the body 2 has a first contact surface 22 and a sound outlet 21. Further referring to... Figure 3 As shown in the figure, the first contact surface 22 of the earphone is opposite to the observer from the perspective of the figure, and the earphone is worn on the left ear.

[0080] Figure 4 This is a schematic diagram of the structure of the human ear 7 in this embodiment. Figure 5 and Figure 6 This is a schematic diagram of the wearing state of the headphones in this embodiment. Figure 6 The volume of the concha 72 in the middle is compared to Figure 5 Larger.

[0081] Further reference Figures 4-6 As shown in the figure, the outline of the left ear is displayed. When the earphone is worn on the left ear, the first contact surface 22 fits against the concha cavity 72 of the left ear, and the sound outlet 21 faces the ear canal 71. The antihelix 73 surrounds the back side of the ear canal 71, and the fixing part 1 is used to fit against the antihelix 73.

[0082] Figure 7 This is an exploded view of the headphones provided in the first embodiment. Figure 8 This is an exploded view of the fixing part 1 provided in the first embodiment. Figure 11 This is an exploded schematic diagram of the headphones provided in the second embodiment. Figure 12 This is an exploded view of the fixing part 1 provided in the second embodiment.

[0083] In some implementations, such as Figures 7-8 and Figures 11-12 As shown, the fixing part 1 includes a fixing arm 11 and a first elastic member 41. The fixing arm 11 has a second contact surface 111, a free end 112, and a connecting end 113, which is rotatably connected to the body 2. The first elastic member 41 generates a spring force that drives the free end 112 to rotate away from the body 2; that is, the first elastic member 41 is configured to drive the free end 112 to rotate away from the body 2. A locking part 3 is provided on the body 2, and when the free end 112 is in a retracted state close to the body 2, the locking part 3 is unclampedly connected to the fixing arm 11. That is, the locking part 3 causes the fixing arm 11 to fit against the body 2.

[0084] Further reference Figure 3 As shown, in the direction away from the first contact surface 22 of the earphone, the sound outlet 21 is located on the side of the body 2 away from the connection end 113, and the sound outlet 21 is inclined relative to the reference line I along a preset direction. The second contact surface 111 (around the center point Ia) extends from the connection end 113 to the free end 112 along the preset direction, and the second contact surface 111 is away from the body 2 and bends away from the body 2.

[0085] It is easy to understand that reference line I in this application is a virtual line, and center point Ia is a virtual point. That is, reference line I and center point Ia do not exist in the actual product. Figure 3 In the direction shown, the headphones are positioned at the wearing angle, with reference line I horizontally set. The dotted line between the center of the sound outlet 21 and center point Ia is rotated approximately 30 degrees counterclockwise relative to reference line I. Most of the fixing part 1 is located above reference line I. The second contact surface 111 extends approximately 100 degrees circumferentially from center point Ia.

[0086] Specifically, the earphone can be configured as a wireless earphone or a wired earphone. When the earphone is configured to fit the left ear, in the direction away from the first contact surface 22, the sound outlet 21 is tilted counterclockwise relative to the reference line I, and the second contact surface 111 extends counterclockwise (e.g., Figure 3 (As shown). When the earphone is configured to fit the right ear (not shown in the figure), in the direction away from the first contact surface 22, the sound outlet 21 is tilted clockwise relative to reference line I, and the second contact surface 111 extends clockwise. An ear cap can be placed at the sound outlet 21 position, thus forming an in-ear earphone. Figure 2 As shown, the body 2 has a gap 26. When the fixing part 1 is locked by the locking part 3, the side of the fixing arm 11 near the body 2 will enter the gap 26.

[0087] In this embodiment, the second contact surface 111 is used to contact the antihelix 73. The elastic force generated by the first elastic member 41 can act on the antihelix 73, so that the earphone is stably placed in the concha cavity 72, preventing the earphone from falling off during wear. In addition, the second contact surface 111 is curved, so that the fixing part 1 can adjust the unfolding range according to the size of the concha cavity 72. This improves the adaptability and wearing comfort of the earphone. The locking part 3 is used to lock or unlock the fixing part 1, so that the fixing part 1 can be switched from the unfolded state to the retracted state. For example, when the wearer wears the earphone for a long time, causing the fixing part 1 to put pressure on the antihelix 73 for a long time, the wearer can retract the fixing part 1 to reduce the pressure on the antihelix 73. Alternatively, when the wearer's concha cavity 72 is small, the fixing part 1 can also be retracted directly. Meanwhile, the sound outlet 21 is located on the main body 2 away from the connecting end 113. The pressure between the fixing arm 11 and the antihelix 73 causes the ear cap to shrink and deform, thereby driving the sound outlet 21 to move inward toward the ear canal 71, preventing the headphones from falling off during exercise.

[0088] Furthermore, the fixing arm 11 also has a third contact surface 114. The third contact surface 114 is adjacent to the second contact surface 111 and faces the same direction as the first contact surface 22. When the wearer wears the headphones, the third contact surface 114 fits against the concha 72 to further improve the fixing effect of the fixing arm 11.

[0089] In summary, in this embodiment, the earphone has its connecting end 113 of the fixing part 1 rotatably connected to the body 2, and the second contact surface 111 is located on the side away from the body 2 and bent away from the body 2. Thus, on one hand, the sound outlet 21 is located on the side of the body 2 away from the connecting end 113, and the extending direction of the second contact surface 111 is consistent with the tilting direction of the sound outlet 21. When the sound outlet 21 faces the ear canal 71, the second contact surface 111 can abut against the antihelix 73, allowing the earphone to be stably positioned within the concha 72, preventing it from easily falling out. On the other hand, the first elastic member 41 is configured to drive the fixing part 1 away from the body 2, further increasing the pressure exerted by the fixing part 1 on the antihelix 73. Furthermore, the first elastic member 41 provides elasticity, allowing the fixing arm 11 to extend to different angles, helping the fixing part 1 adapt to different sizes of concha 72, thereby improving the earphone's adaptability and wearing comfort. On the other hand, the locking part 3 can keep the fixing part 1 in a retracted state, so that the wearer can adjust the wearing method of the headphones in a timely manner according to different usage scenarios.

[0090] In some implementations, such as Figures 7-8 and Figures 11-12 As shown, the fixing arm 11 includes a connector 12 and an elastic contact 13. The elastic contact 13 has a second contact surface 111 and a free end 112. The connector 12 is disposed on the side of the elastic contact 13 opposite to the second contact surface 111, and the connecting end 113 is disposed at one end of the connector 12. In this embodiment, the elastic contact 13 can deform when in contact with the concha 72, reducing the discomfort caused to the ear 7 by the fixing arm 11 during prolonged earphone wear.

[0091] In some implementations, such as Figures 2-3 As shown, the free end 112 has an arcuate surface. The free end 112 extends toward the side of the connector 12 away from the connecting end 113, and the arcuate surface bends toward the side away from the connecting end 113.

[0092] Specifically, in this embodiment, the curved surface is a spherical crown. Further referencing... Figures 4-5 As shown, the location where the helix foot 75 intersects with the concha 74 has a recessed structure. When the fixing part 1 is in a position close to the body 2, the free end 112 will be closer to the concha 74. In this configuration, the wearer can insert the free end 112 into the recessed structure to further secure the earphone. The elastic contact 13 can be made of materials such as silicone, rubber, or foam.

[0093] In some implementations, such as Figures 7-8 and Figures 11-12As shown, the elastic contact 13 is an elastic rod, with a free end 112 disposed at one end of the elastic rod. The connector 12 includes a fixing beam 122, at least a portion of which is disposed inside the elastic rod, and both the fixing beam 122 and the elastic rod are bent away from the body 2. The connecting end 113 is disposed at one end of the fixing beam 122 and is located on the side of the fixing beam 122 away from the elastic rod.

[0094] In this embodiment, the fixing beam 122 is arranged along the length of the elastic rod, and the fixing beam 122 bends together with the elastic rod, so that the fixing arm 11 can better adapt to the shape of the outer surface of the body 2 and the inner surface of the antihelix 73. The fixing beam 122 can support the elastic rod and prevent the elastic rod from bending excessively.

[0095] Figure 9 This is an exploded schematic diagram of the lock part 3 provided in the first embodiment. Figure 13 This is an exploded view of the lock part 3 provided in the second embodiment.

[0096] In some implementations, such as Figures 7-8 and Figures 11-12 As shown, the main body 2 includes an earphone shell, which has a sound outlet 21, a first contact surface 22, and a connection hole 23. The connection hole 23 is located on the side of the earphone shell opposite to the first contact surface 22. Further referencing... Figure 1 and Figure 3 As shown, the lock part 3 has a driving member 31 and a second elastic member 42. The driving member 31 includes an operating handle 311, which extends from the connecting hole 23. Further referencing... Figure 9 and Figure 13 As shown, the drive component 31 moves axially along the connecting hole 23 (e.g., Figure 9 and Figure 13 (As indicated by the arrow in the diagram), the driving member 31 abuts against the second elastic member 42. The second elastic member 42 generates a restoring force that drives the driving member 31 to move outward toward the earphone shell; that is, the second elastic member 42 is configured to drive the driving member 31 to move outward toward the earphone shell. The driving member 31 includes a first position 51 and a second position 52 in the direction of movement.

[0097] In this embodiment, when the driving member 31 is in the first position 51, the locking part 3 is connected to the connecting member 12. In this configuration, the end of the operating handle 311 extends a certain length from the connecting hole 23, allowing the wearer to press the operating handle. 3 11. The fixed arm 11 is unlocked directly. This simplifies the unlocking operation of the headphones, allowing the wearer to unlock them directly while they are wearing them. When the driving member 31 is in the second position 52, that is, after the driving member 31 moves inward towards the inside of the headphone shell, the locking part 3 releases the connecting member 12. Driven by the first elastic member 41, the fixed arm 11 springs away from the body 2.

[0098] Figure 10 This is a schematic diagram of the working state of the lock part 3 provided in the first embodiment.

[0099] In some implementations, such as Figures 8-10 As shown, the locking part 3 also includes a third elastic member 43 and a limiting body 32. The third elastic member 43 includes two elastic arms 431, each with a bent end 432. The two bent ends 432 bend in a direction away from each other, that is, the two bent ends 432 bend in opposite directions. The limiting body 32 is disposed on the driving member 31 and includes two limiting rods 321 corresponding to the two elastic arms 431. The connecting member 12 has a slot 121 with an opening 1211 and two limiting surfaces 1212. The opening 1211 faces the body 2, and the two limiting surfaces 1212 are formed on the inner wall of the slot 121 and located on both sides of the opening 1211. The two limiting surfaces 1212 face the bottom of the slot 121, that is, the orientation of the two limiting surfaces 1212 is opposite to the orientation of the opening 1211.

[0100] When the drive component 31 is in the first position 51, the two bent ends 432 extend into the slot 121 through the opening 1211 and abut against the two limiting surfaces 1212 (e.g., Figure 10 (As shown in state III). During the movement of the driving member 31 from the first position 51 to the second position 52, the two limiting rods 321 press the two elastic arms 431 closer together, and the two bent ends 432 separate from the two limiting surfaces 1212 and move to the opening 1211. In this form, the elastic force of the first elastic member 41 can drive the fixed arm 11 to spring open. Thus, the locking and unlocking operations of the locking part 3 on the fixed arm 11 are realized, while saving the space occupied by the locking part 3 inside the body 2.

[0101] In some implementations, such as Figures 9-10 As shown, the bent end 432 has a mating surface 4321 facing the fixed arm 11. The slot 121 also has two guide ramps 1213 corresponding to the two mating surfaces 4321 respectively. The opposite sides of the two guide ramps 1213 form openings 1211, and the opposite sides of the two guide ramps 1213 extend toward the bottom of the slot 121 and bend away from each other. When the fixed arm 11 rotates toward the body 2, the two guide ramps 1213 press against the corresponding mating surfaces 4321 respectively, thereby forcing the two elastic arms 431 to move closer to each other (e.g., ...). Figure 10 (As indicated by the arrow in state II), until the two bent ends 432 enter the slot 121 through the opening 1211, and then the two bent ends 432 engage with the slot 121 (as shown by the arrow in state II). Figure 10 (As indicated by the arrow in state III).

[0102] Specifically, the ends of the two curved ends 432 are inclined toward the body 2, causing the mating surface 4321 to bend toward the fixing arm 11. Thus, the mating surface 4321 can stably contact the guide slope 1213, ensuring that the elastic arm 431 can successfully engage with the slot 121. The mutual cooperation between the two guide slopes 1213 and the two mating surfaces 4321 in this embodiment simplifies the locking process of the fixing arm 11, allowing the wearer to directly press down on the fixing arm 11 to retract it when wearing the headphones.

[0103] In some implementations, such as Figures 9-10 As shown, the limiting rod 321 includes a curved section 3211 and a straight section 3212 in the length direction, with the straight section 3212 extending axially along the connecting hole 23. One end of the curved section 3211 is connected to the straight section 3212, and the other end bends towards the opposite side of the two curved sections 3211. When the driving member 31 is in the first position 51, the two straight sections 3212 are located on both sides of the two elastic arms 431. During the process of the driving member 31 moving from the first position 51 to the second position 52, the two curved sections 3211 respectively abut against the two elastic arms 431, causing the two elastic arms 431 to move closer to each other.

[0104] Specifically, such as Figure 9 As shown, the limiting body 32 has a fork-shaped structure, including a tail section 322 and two limiting rods 321. The tail section 322 is fixedly connected to the driving member 31, and the two limiting rods 321 are connected to both ends of the tail section 322 and extend out from the driving member 31. When the driving member 31 is in the first position 51, the two straight sections 3212 can limit the opening range of the two elastic arms 431, ensuring that the two mating surfaces 4321 can abut against the two guide inclined surfaces 1213 respectively. At the same time, when the wearer presses the operating handle 311, it ensures that the two curved sections 3211 can abut against the edges of the two elastic arms 431.

[0105] Preferably, the operating handle 311 has two laterally protruding positioning wings 314, which are respectively positioned corresponding to the two curved sections 3211. When the two curved sections 3211 abut against the two elastic arms 431, the two positioning wings 314 abut against the two curved ends 432 from the side of the two curved sections 3211 away from the third elastic member 43, thereby preventing the two limiting rods 321 from opening to both sides. Thus, during repeated use of the lock part 3, deformation of the two limiting rods 321 is effectively prevented, ensuring that the elastic arms 431 can smoothly separate from the slot 121.

[0106] Furthermore, such as Figures 7-8As shown, the earphone shell includes a front shell and a rear shell. The front shell has a first contact surface 22 and a sound outlet 21. The rear shell has a connection hole 23. The front shell and the rear shell are fastened together, forming a gap 26 on opposite sides. The earphone shell also includes a first sidewall 25, which protrudes from the front shell and extends to the top of the front shell. The first sidewall 25 forms the bottom area of ​​the gap 26. When the wearer presses the operating handle 311, the positioning wing 314 moves toward and abuts against the first sidewall 25. This limits the pressure applied by the wearer. In addition, the positioning wing 314 can also abut against the edge of the connection hole 23 to prevent the drive member 31 from being pushed out of the connection hole 23 by the second elastic member 42.

[0107] In some implementations, such as Figures 9-10 As shown, the third elastic member 43 also includes a deformation section 433, which bends away from the slot 121 to form a clearance space 434. Two elastic arms 431 are connected to the two ends of the deformation section 433, and the deformation section 433 generates an elastic force that drives the two elastic arms 431 away from each other. The driving member 31 also includes a first connecting handle 312, one end of which is connected to the operating handle 311, and the other end passes through the clearance space 434 and abuts against the second elastic member 42. The deformation section 433 extends and deforms in a free state, thereby driving the two elastic arms 431 away from each other.

[0108] Furthermore, such as Figure 7 and Figure 8 As shown, in the axial cross-sectional direction of the connecting hole 23, the deformable section 433 extends along a circular arc. The first sidewall 25 is recessed towards the center of the earphone shell to form a first receiving groove 24 and a second receiving groove 27. The front shell has a mounting hole 28. The second elastic member 42 is a compression spring and is disposed within the mounting hole 28. The deformable section 433 is disposed within the second receiving groove 27, and two elastic arms 431 extend from the second receiving groove 27 into the gap 26. This further reduces the space occupied by the locking part 3 on the body 2, thereby freeing up more space for components such as speakers inside the body 2.

[0109] In some implementations, such as Figures 11-13 As shown, the fixed arm 11 also includes a first magnetic body 61, which is disposed on the connector 12. The driving member 31 also includes a second connecting handle 313 and a second magnetic body 62, which is disposed on the second connecting handle 313. The second connecting handle 313 has a first fixing groove 3131 facing the fixed arm 11, and the second magnetic body 62 is disposed in the first fixing groove 3131.

[0110] When the driving member 31 is in the first position 51 and the fixing arm 11 is close to the body 2, the first magnetic body 61 and the second magnetic body 62 are positioned opposite each other and attract each other, causing the fixing arm 11 to be in a retracted state. When the driving member 31 is in the second position 52, the first magnetic body 61 and the second magnetic body 62 are misaligned, causing the magnetic attraction between the first magnetic body 61 and the second magnetic body 62 to disappear or weaken. As a result, the elastic force of the first elastic member 41 can drive the fixing arm 11 to spring open, simplifying the wearer's unlocking operation.

[0111] In some implementations, such as Figures 11-13 As shown, the second connecting handle 313 also has a second fixing groove 3132, which faces the same direction as the first fixing groove 3131 and is spaced a predetermined distance apart along the axial direction of the second connecting handle 313. The driving member 31 also includes a third magnetic body 63, which is disposed on the second connecting handle 313. The third magnetic body 63 has the same polarity as the first magnetic body 61, that is, the polarity of the third magnetic body 63 is opposite to that of the second magnetic body 62. When the fixing arm 11 is in a position close to the body 2 and the driving member 31 is in the second position 52, the third magnetic body 63 is opposite to the first magnetic body 61. Therefore, the magnetic force between the third magnetic body 63 and the first magnetic body 61 can accelerate the opening of the fixing arm 11. The third magnetic body 63 is disposed in the second fixing groove 3132.

[0112] Furthermore, the north pole of the second magnetic body 62 and the south pole of the third magnetic body 63 face the first magnetic body 61. The south pole of the first magnetic body 61 faces the second connecting handle 313. This simplifies the internal structure of the lock part 3.

[0113] In some implementations, such as Figures 7-8 and Figures 11-12 As shown, the main body 2 has a first receiving groove 24. A connecting end 113 is rotatably disposed in the first receiving groove 24, and the connecting end 113 has a receiving hole 1131. The first elastic element 41 is a torsion spring, which includes a coil 412 and two driving arms 411 connected to the coil 412. The coil 412 is disposed in the receiving hole 1131, one driving arm 411 is connected to the connecting end 113, and the other driving arm 411 extends out of the receiving hole 1131 and is connected to the main body 2. Thus, in this embodiment, the elastic force of the torsion spring drives the fixed arm 11 away from the main body 2, and the coil 412 disposed in the receiving hole 1131 allows for a more compact internal structure of the earphone.

Various modifications and variations can be made to this utility model by those skilled in the art.
