earphone

Abstract

The utility model discloses an earphone, with the fixed part and the body movable connection, the second contact surface is set to the side away from the body and is curved to the direction away from the body. Therefore, on one hand, the second contact surface can abut against the antihelix, so that the earphone can be stably arranged in the concha cavity, avoiding it from falling easily. On the other hand, the first elastic piece is configured to drive the fixed part away from the body, further increasing the pressure applied by the fixed part to the antihelix. In addition, the first elastic piece provides elastic force, so that the fixed arm can be unfolded to different angles, which helps the fixed part to adapt to different sizes of the concha cavity, thereby improving the adaptability of the earphone and the comfort during wearing. At the same time, the gap makes the fixed part more fit the body when it is in the retracted state.

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 movably 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] The earphones in this embodiment of the utility model include:

[0005] Lock part;

[0006] The body includes a first contact surface and a gap; and

[0007] The fixing part is movably connected to the body and includes a fixing arm and a first elastic member. The fixing arm has a pressing area, a second contact surface, a third contact surface and a free end. The first elastic member is configured to drive the free end to move away from the body. The third contact surface is adjacent to the second contact surface and has the same orientation as the first contact surface.

[0008] In the direction away from the first contact surface of the earphone, the second contact surface extends toward the free end in a preset direction, and the second contact surface is away from the body and bends away from the body.

[0009] The locking part is configured to apply a first pressing force to the fixed arm through the pressing area, with the free end close to the body, the body locking to the fixed arm through the locking part, and the side of the fixed arm close to the body entering the gap; and to apply a second pressing force to the fixed arm through the pressing area, with the locking part releasing the fixed arm.

[0010] Furthermore, the body also includes a sound outlet;

[0011] 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.

[0012] The fixed arm includes an elastic contact element, the elastic contact element having the second contact surface and the free end;

[0013] The free end has an arc surface, and the arc surface is curved along the preset direction.

[0014] Furthermore, the fixed arm also includes a connector, which is disposed on the side of the elastic contact member opposite to the second contact surface, and the connector has a connecting end, which is rotatably connected to the body.

[0015] Furthermore, the elastic contact element is configured as an elastic rod, and the free end is disposed at one end of the elastic rod;

[0016] 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.

[0017] Furthermore, the locking part includes:

[0018] A locking lever, rotatably connected to the body and including a locking hook; and

[0019] A connecting block protrudes from the side of the fixed beam away from the elastic rod. The connecting block is provided with a sliding groove on its side. The sliding groove includes an inlet / outlet, a first sliding section, a second sliding section, and a locking section.

[0020] The locking mechanism is further configured such that: the first pressing force causes the fixed beam to swing toward the body, the locking hook enters the first sliding interval from the inlet / outlet, the first elastic element causes the fixed beam to move away from the body, and the locking hook slides to the locking area; the second pressing force causes the fixed beam to swing toward the body, the locking hook moves from the locking area to the second sliding interval, the first elastic element causes the fixed beam to move away from the body, and the locking hook passes through the second sliding interval and moves out from the inlet / outlet.

[0021] Furthermore, the body has a first receiving groove;

[0022] The first elastic element is a torsion spring, which includes a coil body and two first drive arms connected to the coil body;

[0023] The ring body is disposed in the first receiving groove, one of the first driving arms is connected to the connector, and the other of the first driving arms extends out from the first receiving groove and is connected to the body.

[0024] Furthermore, the locking part includes a first magnetic body and a second magnetic body, the first magnetic body being disposed on the body and the second magnetic body being disposed on the fixing arm;

[0025] The elastic contact element is an elastic rod, and one end of the elastic rod forms the free end;

[0026] The first elastic member includes a second drive arm and a connecting segment in the length direction. The second drive arm passes through the elastic rod and is spaced apart from the body in the free state. The connecting segment extends out from the elastic rod and includes a bent deformation zone. The end of the connecting segment is fixedly connected to the body, and the deformation zone is configured to drive the free end to move away from the body.

[0027] The pressing area is formed on the second contact surface and is disposed opposite to at least a portion of the second drive arm;

[0028] The locking part is configured such that when the first pressing force drives the fixing arm to approach the body, the deformation area bends and deforms until the first magnetic body and the second magnetic body are attracted; and a second pressing force is applied to the second driving arm through the pressing area, the second driving arm bends toward the body, and drives the second magnetic body to separate from the first magnetic body.

[0029] Furthermore, the second drive arm includes a protruding section. In the free state, the protruding section bends away from the body and corresponds to the pressing area. The second pressing force causes the protruding section to extend and deform.

[0030] Furthermore, the fixed arm also includes a first fixed block and a second fixed block, which are disposed on the elastic rod and fixedly connected to both ends of the second drive arm;

[0031] The second magnetic body is disposed inside the first fixing block.

[0032] Furthermore, the sides of the first fixing block and the second fixing block closest to the body are exposed on the outside of the elastic rod;

[0033] The fixed arm abuts against the body through the first fixed block and the second fixed block, and the second pressing force can drive the first fixed block to slide to one side of the first magnetic body.

[0034] The earphone of this embodiment features a fixing part movably connected to the main body, with the second contact surface positioned on the side away from the main body and bent away from it. This allows the second contact surface to abut against the antihelix, ensuring the earphone is stably positioned within the concha and preventing it from easily falling out. Furthermore, 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. Additionally, the first elastic member provides elasticity, allowing the fixing arm to extend to different angles, helping the fixing part adapt to different sizes of conchae and improving the earphone's adaptability and wearing comfort. Moreover, the locking part keeps the fixing part in a retracted state, allowing the wearer to adjust the earphone's wearing method according to different usage scenarios. Furthermore, the pressing area on the fixing arm makes the earphone's appearance more streamlined and simplifies the operation of the locking part. Simultaneously, the gap allows the fixing part to fit more snugly against the main body when retracted. Attached Figure Description

[0068] 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.

[0069] 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.

[0070] 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".

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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 (not shown in the above figures). 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, the first contact surface 22 of the earphone is opposite to the observer from the perspective of the image, and the earphone is worn on the left ear. The fixing part 1 is movably connected to the body 2, that is, the fixing part 1 can move relative to the body 2. The fixing part 1 includes a fixing arm 11 and a first elastic member 41. The fixing arm 11 has a pressing area 114, a second contact surface 111, and a free end 112. The first elastic member 41 generates a spring force that drives the free end 112 to move away from the body 2.

[0076] Figure 4This 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.

[0077] Further reference Figures 4-6 As shown in the figure, the outline of the left ear is illustrated. When the earphone is worn on the left ear, the first contact surface 22 fits against the concha 72 of the left ear, and the sound outlet 21 faces the ear canal 71. The antihelix 73 surrounds the rear side of the ear canal 71, and the fixing part 1 is used to fit against the antihelix 73. 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 fixing part 1, and the sound outlet 21 is inclined along a preset direction and relative to the reference line I. The second contact surface 111 extends towards the free end 112 along a preset direction, and the second contact surface 111 is away from the body 2 and bends away from the body 2.

[0078] 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.

[0079] 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.

[0080] 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 it for a long time, the fixing part 1 causes long-term pressure on the antihelix 73. 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. At the same time, the sound outlet 21 is located on the body 2 away from the fixing arm 11. The pressure between the fixing arm 11 and the antihelix 73 causes the ear cap to contract and deform, thereby driving the sound outlet 21 to move inward toward the ear canal 71, preventing the earphone from falling off during movement.

[0081] Furthermore, the fixing arm 11 also has a third contact surface 117. The third contact surface 117 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 117 fits against the concha 72 to further improve the fixing effect of the fixing arm 11.

[0082] Figure 7 This is an exploded view of the headphones provided in the first embodiment. Figure 8 and Figure 9 This is a partial schematic diagram of the headphones provided in the first embodiment. Figure 13 and Figure 14 This is an exploded schematic diagram of the headphones provided in the second embodiment. Figure 15 This is an exploded view of the fixed arm 11 provided in the second embodiment.

[0083] In some implementations, such as Figures 7-9 and Figures 13-15 As shown, the locking part 3 is configured such that the wearer's finger applies a first pressing force to the fixing arm 11 through the pressing area 114, and the free end 112 is close to the body 2. The body 2 is unclampedly connected to the fixing arm 11 through the locking part 3. That is, the locking part 3 locks the fixing arm 11 to the body 2. The fixing part 1 is also configured such that the wearer's finger applies a second pressing force to the fixing arm 11 through the pressing area 114, and pressing again causes the locking part 3 to release the fixing arm 11. Thus, in this embodiment, the locking and unlocking operations of the locking part 3 are realized by the pressing area 114 provided on the fixing arm 11, simplifying the control method of the locking part 3 and making the appearance of the headphones more concise.

[0084] In summary, in this embodiment, the earphone has a fixing part 1 movably 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 fixing part 1, 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 placed 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. Additionally, the locking part 3 can keep the fixing part 1 in a retracted state, allowing the wearer to adjust the earphone wearing method according to different usage scenarios. Furthermore, the pressing area 114 is located on the fixing arm 11, which makes the appearance of the headphones more concise and simplifies the operation of the locking part 3. At the same time, the gap 26 allows the fixing part 1 to fit more snugly with the body 2 when it is in the retracted state.

[0085] In some implementations, such as Figures 7-9 and Figures 13-15 As shown, the fixed arm 11 includes an elastic contact 13, which has a second contact surface 111 and a free end 112. The free end 112 has an arc surface, and the arc surface is bent in a preset direction. In this embodiment, the elastic contact 13 can deform when it comes into contact with the concha 72, thereby reducing the discomfort caused to the ear by the fixed arm 11 when the earphone is worn for a long time.

[0086] 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.

[0087] Figure 10 This is an exploded view of the fixed arm 11 provided in the first embodiment.

[0088] In some implementations, such as Figures 7-10 As shown, the fixed arm 11 also includes a connector 12. The connector 12 is disposed on the side of the elastic contact member 13 opposite to the second contact surface 111, and the connector 12 has a connecting end 113, which is rotatably connected to the body 2.

[0089] Specifically, such as Figure 7 As shown, the connecting end 113 includes a rotating shaft 1131, and the body 2 includes a first connecting hole 23. The rotating shaft 1131 is rotatably inserted into the first connecting hole 23 to achieve a rotatable connection between the connector 12 and the body 2. In this embodiment, the connector 12 has a certain rigidity to facilitate the rotation of the elastic contact member 13.

[0090] In some implementations, such as Figures 7-10 As shown, the elastic contact 13 is configured as an elastic rod, with a free end 112 disposed at one end of the elastic rod. The connector 12 includes a fixing beam 121, at least a portion of which is disposed inside the elastic rod, and both the fixing beam 121 and the elastic rod are bent away from the body 2. The connecting end 113 is disposed at one end of the fixing beam 121 and is located on the side of the fixing beam 121 away from the elastic rod.

[0091] In this embodiment, the fixing beam 121 is arranged along the length of the elastic rod, and the fixing beam 121 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 121 can support the elastic rod and prevent the elastic rod from bending excessively.

[0092] Figure 11 This is a cross-sectional schematic diagram of the connecting block 32 in the embodiment. Figure 12 This is a schematic diagram of the slide groove 321 in the embodiment. Figure 12 The image shows the direction of movement of the locking hook 311 within the slide groove 321.

[0093] In some implementations, such as Figures 9-10 As shown, the locking part 3 includes a locking rod 31 and a connecting block 32. The locking rod 31 is rotatably connected to the body 2, and the locking rod 31 includes a locking hook 311. The connecting block 32 protrudes from the side of the fixed beam 121 away from the elastic rod, and a sliding groove 321 is provided on the side of the connecting block 32, that is, the sliding groove 321 is located on the side of the connecting block 32 near the first contact surface 22 or away from the first contact surface 22. The orientation of the sliding groove 321 is parallel to the rotation axis of the rotating shaft 1131. Further referencing... Figures 11-12 As shown, the slide 321 includes an inlet / outlet 323, a first sliding section 324, a second sliding section 325, and a locking section 322.

[0094] When the wearer retracts the fixing arm 11, the locking part 3 is configured such that the wearer's finger applies a first pressing pressure, causing the fixing beam 121 to swing towards the body 2. This allows the locking hook 311 to enter the first sliding section 324 from the inlet / outlet 323. Then, the first elastic member 41 moves the fixing beam 121 away from the body 2, causing the locking hook 311 to slide to the locking area 322. This completes the locking of the locking part 3 onto the fixing arm 11.

[0095] When the wearer unfolds the fixed arm 11, the lock part 3 is also configured to apply a second pressing pressure with the wearer's fingers to drive the fixed beam 121 to swing toward the body 2. The locking hook 311 moves from the locking area 322 to the second sliding area 325, and then the first elastic member 41 drives the fixed beam 121 away from the body 2, so that the locking hook 311 passes through the second sliding area 325 and moves out from the entrance 323.

[0096] In this embodiment, the slide groove 321 and the locking lever 31 form a press-type self-locking mechanism. When the wearer presses down on the pressing area 114 for the first time, the fixing arm 11 can be locked. When the wearer presses down on the pressing area 114 for the second time, the fixing arm 11 can be unlocked. This simplifies the way the wearer drives the lock part 3.

[0097] Furthermore, such as Figure 9 As shown, the main body 2 has a second connecting hole 29, with a lateral limiting notch 291 formed in the second connecting hole 29. The locking rod 31 includes a locking hook 311, a bent section 312, and a transition section 313. The bent section 312 connects the locking hook 311 and the transition section 313. The transition section 313 rotatably extends into the second connecting hole 29, and the bent section 312 extends out from the limiting notch 291, engaging with the edge of the limiting notch 291 to limit the swing amplitude of the locking rod 31. This ensures that the locking hook 311 can smoothly enter or exit the inlet / outlet 323.

[0098] Figure 11 and Figure 12 The figure illustrates a specific form of the slide groove 321. The slide groove 321 faces the side of the connecting block 32, and a portion of the bottom surface of the slide groove 321 protrudes towards the side of the connecting block 32. Along the extending direction of the slide groove 321, a first boss 51, a second boss 52, a third boss 53, a fourth boss 54, a fifth boss 55, a sixth boss 56, a seventh boss 57, and an eighth boss 58 are sequentially formed. The first boss 51, the fourth boss 54, the sixth boss 56, and the eighth boss 58 have a slope. In the moving direction of the locking hook 311, the platform height of the first boss 51, the fourth boss 54, and the sixth boss 56 gradually increases, while the platform height of the eighth boss 58 gradually decreases.

[0099] The surfaces of the second protrusion 52, the third protrusion 53, the fifth protrusion 55, and the seventh protrusion 57 are not sloped. The second protrusion 52 is higher than the third protrusion 53, and is level with the higher side of the first protrusion 51. The third protrusion 53 is level with the lower side of the fourth protrusion 54. The fifth protrusion 55 is level with the lower side of the sixth protrusion 56, and is lower than the fourth protrusion 54. The seventh protrusion 57 is level with the higher side of the eighth protrusion 58, and is lower than the fifth protrusion 55. A groove 321 is formed by a recess from one side of the connecting block 32 to the other side. The groove 321 extends clockwise from the inlet / outlet 323 and returns to the inlet / outlet 323. A central step 591 is formed at the center of the groove 321. The central step 591 has a limiting groove 592 on the side away from the second connecting hole 29. The limiting groove 592 is C-shaped in the cross-sectional direction of the height of the central step 591 and is recessed from the side of the central step 591 toward the second connecting hole 29. The limiting groove 592 is adjacent to the fifth boss 55 and together they form the aforementioned locking area 322.

[0100] Further reference Figures 11-12 As shown, when the wearer applies the first pressing pressure, the fixing arm 11 moves in the direction indicated by arrow a1, and the locking hook 311 enters the first sliding section 324 from the inlet 323. The locking hook 311 moves along the side wall of the first sliding section 324 away from the central step 591 to the third protrusion 53. Then, when the wearer releases the fixing arm 11, under the action of the first elastic member 41, the fixing arm 11 moves in the direction indicated by arrow a2, and the locking hook 311 slides through the fourth protrusion 54 to the fifth protrusion 55 and abuts against the side wall of the limiting groove 592. In this configuration, the fixing arm 11 can stably fit against the body 2. When the wearer applies the second pressing pressure, the fixing arm 11 moves again in the direction indicated by arrow a1, and the locking hook 311 remains in contact with the side wall of the fourth protrusion 54 facing the fifth protrusion 55, and slides from the fifth protrusion 55 through the sixth protrusion 56 to the seventh protrusion 57. Then, when the wearer releases the fixing arm 11, the fixing arm 11 moves in the direction shown by arrow a2 under the action of the first elastic element 41, and the locking hook 311 will also disengage from the entrance 323 along the eighth protrusion 58. During the above process, the locking hook 311 moves along the side wall of the second sliding section 325 away from the central step 591. When the locking hook 311 climbs up along the protrusion, the bending section 312 can also generate elastic deformation to ensure that the end of the locking hook 311 is in contact with the bottom surface of the slide groove 321.

[0101] In some implementations, such as Figures 8-10As shown, the body 2 has a first receiving groove 24. The first elastic element 41 is a torsion spring, which includes a coil 414 and two first driving arms 413 connected to the coil 414. The coil 414 is disposed in the first receiving groove 24, one first driving arm 413 is connected to the connector 12, and the other first driving arm 413 extends out of the first receiving groove 24 and is connected to the body 2.

[0102] Furthermore, such as Figures 8-9 As shown, the main body 2 includes an earphone shell. The earphone shell includes a front shell and a rear shell, the front shell having a first contact surface 22 and a sound outlet 21. 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 region of the gap 26. The first sidewall 25 is recessed toward the center of the earphone shell to form a first receiving groove 24 and a second receiving groove 27. When the wearer applies a first pressing pressure and a second pressing pressure, the connecting block 32 will enter the second receiving groove 27 and abut against the first sidewall 25, thereby limiting the range of movement of the fixing arm 11. This ensures that the locking hook 311 can slide to a predetermined position.

[0103] Preferably, the connecting block 32 is disposed at one end of the fixed beam 121, the connecting end 113 is disposed at the other end of the fixed beam 121, and a first driving arm 413 is connected to the middle region of the fixed beam 121. This increases the driving torque of the first elastic element 41, making it easier for the first elastic element 41 to spring the fixed arm 11 away.

[0104] Figure 16 This is a schematic diagram of the structure of the fixed arm 11 provided in the second embodiment.

[0105] In some implementations, such as Figures 13-16 As shown, the lock part 3 includes a first magnetic body 61 and a second magnetic body 62. The first magnetic body 61 is disposed in the body 2, and the second magnetic body 62 is disposed in the fixed arm 11. The elastic contact member 13 is an elastic rod, one end of which forms a free end 112. The first elastic member 41 includes a second drive arm 411 and a connecting section 412 in the length direction. The second drive arm 411 passes through the elastic rod and is spaced apart from the body 2 in the free state. The connecting section 412 extends from the elastic rod and includes a bent deformation area 4121. The end of the connecting section 412 is fixedly connected to the body 2, and the deformation area 4121 extends and deforms to generate an elastic force that drives the free end 112 to move away from the body 2. That is, the deformation area 4121 is configured to drive the free end 112 to move away from the body 2. The pressing area 114 is formed on the second contact surface 111 and is disposed opposite to at least part of the second drive arm 411.

[0106] The locking part 3 is configured such that when the first pressing force drives the fixing arm 11 close to the body 2, the deformation area 4121 bends and deforms until the first magnetic body 61 and the second magnetic body 62 are attracted together. The locking part 3 is also configured to apply a second pressing force to the second driving arm 411 through the pressing area 114, causing the second driving arm 411 to bend toward the body 2 and drive the second magnetic body 62 to separate from the first magnetic body 61, thereby reducing the magnetic force between the first magnetic body 61 and the second magnetic body 62, so that the first elastic member 41 can spring the fixing arm 11 away.

[0107] In this embodiment, when the second drive arm 411 is pressed down, both ends of the second drive arm 411 extend, thereby causing the second magnetic body 62 to separate from the first magnetic body 61. When the connecting section 412 drives the fixing arm 11 to spring open, the second drive arm 411 will quickly return to its initial state. Thus, the configuration of the first elastic element 41 greatly simplifies the headphone structure and unlocking method.

[0108] Furthermore, such as Figure 14 and Figure 16 As 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 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 and a retaining plate 83, which protrude from the front shell and extend to the top of the front shell. The first sidewall 25 forms the bottom region of the gap 26. The first sidewall 25 is recessed toward the center of the earphone shell to form a third receiving groove 81 and a fourth receiving groove 82. The third receiving groove 81 faces the fixing arm 11 and is used to fix the first magnetic body 61. The retaining plate 83 is located in the fourth receiving groove 82. A connecting segment 412 extends into the fourth receiving groove 82 and its end is connected to the first sidewall 25. A deformation region 4121 is bent. The deformation region 4121 includes a first part and a second part, with the first part closer to the end of the connecting segment 412 relative to the second part. Figure 16 As shown, the first part is sandwiched between the first sidewall 25 and the mounting plate 83. When the fixing arm 11 is in the retracted state, both the first and second parts are in contact with the side of the mounting plate 83. The side of the mounting plate 83 is configured as a curved surface. When the fixing arm 11 is extended, the second part extends and deforms away from the mounting plate 83, thereby driving the second drive arm 411 to move.

[0109] In some implementations, such as Figure 16 As shown, the second drive arm 411 includes a protruding section 4111. In the free state, the protruding section 4111 bends away from the body 2 and corresponds to the pressing area 114. The second pressing force causes the protruding section 4111 to extend and deform.

[0110] Specifically, under the action of the second pressing force, the middle area of ​​the protruding section 4111 moves towards the body 2 relative to its two ends, so that the distance between the two ends of the protruding section 4111 is longer, thereby pushing the free end 112 to move away from the connecting section 412, so as to drive the second magnetic body 62 to separate from the first magnetic body 61.

[0111] In this embodiment, the protruding section 4111 can increase the deformation range of the second drive arm 411, and by placing the protruding section 4111 in the middle position of the second drive arm 411, the second drive arm 411 can be more easily extended and deformed. At the same time, it helps the wearer to find the force application point corresponding to the protruding section 4111 on the elastic contact member 13 during repeated use, and use it as the pressing area 114, which can reduce the driving force of the wearer.

[0112] In some implementations, such as Figure 16 As shown, the fixing arm 11 also includes a first fixing block 115 and a second fixing block 116, which are disposed on the elastic rod and fixedly connected to both ends of the second drive arm 411. A second magnetic body 62 is disposed on the first fixing block 115. In this embodiment, the first fixing block 115 and the second fixing block 116 can play a fixing role, preventing the two ends of the second drive arm 411 from directly tearing the elastic contact member 13.

[0113] In some implementations, such as Figure 16 As shown, the first fixing block 115 and the second fixing block 116 are located on the outer side of the elastic rod near the body 2. The fixing arm 11 abuts against the body 2 through the first fixing block 115 and the second fixing block 116. The second pressing force causes the first fixing block 115 to slide towards the side of the first magnetic body 61. Thus, by using the first fixing block 115 and the second fixing block 116, direct contact between the elastic contact member 13 and the body 2 is avoided, thereby improving the service life of the fixing arm 11.

[0114] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principle of this utility model should be included within the protection scope of this utility model.
