[0026] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In the embodiments described in this disclosure, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can refer to an electrical connection or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0028] The following combination Figures 1 to 15 The headphone device described in the embodiments of this disclosure will be described in detail.

[0029] In this embodiment, the headphone device may include: a second housing 200, a first housing 100, a sound-generating component 410, and a connector 300. The first housing 100 and the second housing 200 are disposed adjacent to each other; the sound-generating component 410 may be disposed within the first housing 100 by means of bonding, snap-fitting, welding, etc.; the connector 300 may include a second end 360 and a first end 350 disposed opposite to each other; the second end 360 of the connector 300 may be connected to the second housing 200 by means of bonding, snap-fitting, welding, etc.; the first end 350 of the connector 300 may be connected to the first housing 100.

[0030] In this embodiment, the first end 350 of the connector 300 is movably connected to the first housing 100. The inventors have found that the size of the headphone structure cannot be adjusted, resulting in poor adaptability. In this application, the first end of the connector 300 is movably connected to the first housing 100, allowing adjustment of the relative positions of the connector 300 and the first housing 100, thereby improving the adaptability of the headphone device.

[0031] The first housing 100 may have a mating side and a connecting side disposed opposite to each other; the second housing 200 may be disposed adjacent to the mating side of the first housing 100; the first end of the connector 300 may be movably connected to the connecting side of the first housing 100. The distance between the mating side of the first housing 100 and the second housing 200 may be smaller than the distance between the connecting side of the first housing 100 and the second housing 200; by movably connecting the side of the first housing 100 farther from the second housing 200 to the first end of the connector 300, the installation space of the connector 300 can be increased, thereby improving the connector 300's ability to adapt to large-sized ears. The manner in which the first end of the connector 300 is movably connected to the connecting side of the first housing 100 is not limited. For example, the first end of the connector 300 and the connecting side of the first housing 100 may be rotatably connected by a pivot structure. Another example is that the first end of the connector 300 and the connecting side of the first housing 100 may be slidably connected.

[0032] In some implementations, the first end 350 of the connector 300 can be connected to the first housing 100 via a connecting structure 500; the first end 350 of the connector 300 and the first housing 100 can be slidably connected via the connecting structure 500 to adjust the length of the first end 350 outside the first housing 100; the first housing 100 can slide to at least one target position relative to the first end 350 of the connector 300 via the connecting structure 500, and at the target position the first housing 100 can rotate relative to the first end 350 to adjust the position of the first housing 100 relative to the second housing 200.

[0033] The inventors discovered that the inability to adjust the position of the sound-generating structure resulted in poor adaptability of the headphone device. In this application, the first end 350 of the connector 300 is slidably connected to the first housing 100, allowing adjustment of the length of the first end 350 outside the first housing 100. This adjusts the length of the connector 300 between the second housing 200 and the first housing 100, thereby improving the headphone device's ability to adapt to different ear sizes. Simultaneously, the first housing 100 can slide to at least one target position relative to the first end 350 of the connector 300. At this target position, the first housing 100 can rotate relative to the first end 350 to adjust its position relative to the second housing 200. This adjustment allows the first housing 100 to fit more snugly against the wearer's ear, and the sound-generating component 410 to better fit the wearer's ear canal, thus improving the audio performance of the sound-generating component 410.

[0034] In this embodiment, the specific structure of the headphone device is not limited. For example, the headphone device can be a clip-on headphone, an ear-hook headphone, etc. This embodiment is described using a clip-on headphone as an example. In the wearing state, the second shell 200 can be located behind the wearer's ear, and the first shell 100 can be located in front of the wearer's ear; the connector 300 can be located at the wearer's auricle, and the connector 300 can contact the wearer's auricle or have a gap with the wearer's auricle.

[0035] In this embodiment of the disclosure, the connector 300 is used to connect the second housing 200 and the first housing 100. For example... Figure 1 , Figure 4 , Figure 6 , Figure 8 and Figure 10 As shown, the second housing 200, the connector 300, and the first housing 100 form a clamping space 640. A clamping gap 650 may exist between the second housing 200 and the first housing 100. When the second housing 200 and the first housing 100 are in contact, the clamping gap 650 is zero; when the second housing 200 and the first housing 100 are spaced apart, the clamping gap 650 is greater than zero. In the wearing state, the portion on the wearer's earlobe side is located in the clamping space 640, and the portion on the ear root side is located between the second housing 200 and the first housing 100. The clamping space 640 and the clamping force between the second housing 200 and the first housing 100 enable the ear-clip headphones to be worn relatively stably on the wearer's ear.

[0036] In the embodiments disclosed herein, the shape of the connector 300 is not limited. For example, the connector 300 may be C-shaped, n-shaped, parabolic, etc. This disclosure does not limit it in this respect.

[0037] The connector 300 can be elastic, allowing the distance between the second housing 200 and the first housing 100 to be adjusted based on the elasticity of the connector 300, thereby making the ear-clip headphones easy to wear. The connector 300 can also be rigid, allowing it to maintain a specific shape, thereby improving the clamping force and wearing stability of the connector 300. The material of the connector 300 is not limited. For example, the material of the connector 300 may include shape memory alloys, polymer materials, etc.

[0038] The second end 360 of the connector 300 and the second housing 200 can be fixedly connected by means of bonding, snap-fitting, welding, etc.

[0039] In some examples, the connector 300 may include a strip and an elastic member 340, the elastic member 340 being wrapped around the strip. The strip may be both elastic and rigid to improve the strength and elasticity of the connector 300. For example, the strip may be made of metal, polymer, etc. As an example, the strip may be made of shape memory alloy. The elastic member 340 may be made of silicone, thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), etc., to improve the wearing comfort of the headphone device. Here, one end of the strip extending beyond the elastic member 340 may form a first end 350 of the connector 300, and the other end of the strip and at least a portion of the elastic member 340 may form a second end 360 of the connector 300; or, the other end of the strip may form the second end 360 of the connector 300.

[0040] In some other examples, the connector 300 may include a strip, a first fastener 310, and a second fastener 320. The first fastener 310 is fixedly connected to one end of the strip by means of bonding, snap-fitting, welding, etc.; the second fastener 320 is fixedly connected to the other end of the strip by means of bonding, snap-fitting, welding, etc. Here, the first fastener 310 may form the first end 350 of the connector 300, and the second fastener 320 may form the second end 360 of the connector 300.

[0041] As an example, such as Figure 13 As shown, the headphone device may further include: an elastic member 340, which may be wrapped around the strip member; at least a portion of a first fixing member 310 may be located outside the elastic member 340 to form a first end 350 of the connector 300, and at least a portion of the first fixing member 310 may be slidably connected to the first housing 100 via a connecting structure 500. A second fixing member 320 may be located within the elastic member 340 and the second housing 200. A portion of the second fixing member 320 and the elastic member 340 may form a second end 360 of the connector 300.

[0042] The first fixing member 310 and the second fixing member 320 can be non-elastic structures to improve connection strength. For example, the first fixing member 310 and the second fixing member 320 can be made of polymer materials, metal materials, etc. As an example, the first fixing member 310 and the second fixing member 320 can be made of plastic, which can both improve connection strength and reduce the weight of the headphone device, thus achieving lightweighting of the headphone device.

[0043] In this embodiment, the second housing 200 may or may not be elastic. For example, the second housing 200 may be a rigid structure and may not be elastic. As an example, the material of the second housing 200 may include metal, plastic, etc. As another example, at least a portion of the second housing 200 may be elastic. The second housing 200 may be partially elastic and partially rigid. As an example, the material of the second housing 200 may include rubber, foam, etc.

[0044] like Figure 3 As shown, in some examples, the power supply 430 and circuit board 420 of the headphone device can be disposed within the second housing 200 by means of adhesive bonding, snap-fitting, soldering, etc. Of course, in other examples, the circuit board 420 can also be disposed within the first housing 100 by means of adhesive bonding, snap-fitting, soldering, etc.

[0045] In some embodiments of this disclosure, at least a portion of the first housing 100 may be located within the concha of the wearer to reduce the distance between the first housing 100 and the wearer's ear canal, thereby improving audio performance.

[0046] The first housing 100 may or may not be elastic. For example, the first housing 100 may be a rigid structure and may not be elastic. As an example, the material of the first housing 100 may include metal, plastic, etc. Alternatively, at least a portion of the first housing 100 may be elastic. The first housing 100 may also be elastic throughout. As an example, the material of the first housing 100 may include rubber, etc. The first housing 100 may also be partially elastic and partially rigid.

[0047] In some examples, such as Figure 1 and Figure 3As shown, the first housing 100 may include a first half-shell 120, a second half-shell 130, and a mating member 140. The first half-shell 120 and the second half-shell 130 may be connected by means of bonding, snap-fitting, welding, etc. A receiving cavity 110 for accommodating structural components of the headphone device may be defined between the first half-shell 120 and the second half-shell 130. The first half-shell 120 may be located on the side of the second half-shell 130 away from the second housing 200, and the second half-shell 130 may be located on the side of the second half-shell 130 facing the second housing 200 by means of bonding, snap-fitting, welding, etc., so that the mating member 140 contacts the wearer's ear. The first half-shell 120 and the second half-shell 130 may be rigid structures. For example, the materials of the first half-shell 120 and the second half-shell 130 may include metal, plastic, etc. The mating member 140 may be elastic. For example, the materials of the mating member 140 may include rubber, foam, etc. Of course, in other examples, the first housing 100 may include only the first half-shell 120 and the second half-shell 130, without including the mating part 140. This disclosure does not limit this.

[0048] When the first housing 100 includes a first half-shell 120 and a second half-shell 130, the first end 350 of the connector 300 can be connected to the first half-shell 120 via the connector structure 500.

[0049] In this embodiment, the sound-generating component 410 can be disposed within the receiving cavity 110 of the first housing 100 by means of bonding, snap-fitting, welding, etc. The sound-generating component 410 can be a structure capable of producing sound, such as a loudspeaker. The sound-generating component 410 can divide the receiving cavity 110 of the first housing 100 into a front cavity 111 and a rear cavity 112. The sound-generating component 410 can include a side on which the diaphragm 411 is disposed and a side opposite to the diaphragm 411. The side on which the diaphragm 411 is disposed can be located on the front cavity 111 side, and the side opposite to the diaphragm 411 can be located on the rear cavity 112 side.

[0050] In some examples, the first housing 100 may have a sound-emitting hole 104 and a through hole 103. The sound-emitting hole 104 may communicate with the front cavity 111, and the through hole 103 may communicate with the rear cavity 112. When the sound-emitting assembly 410 is working, the vibration of the diaphragm 411 can generate sound in the front cavity 111, and the sound in the front cavity 111 is transmitted to the wearer's ear canal through the sound-emitting hole 104. The pressure in the rear cavity 112 can be adjusted through the through hole 103 to improve the audio effect.

[0051] As an example, the first housing 100 may include a first half-shell 120 and a second half-shell 130, and the sound-generating assembly 410 may be disposed within a receiving cavity 110 defined between the first half-shell 120 and the second half-shell 130. A sound-generating hole 104 may be formed in the second half-shell 130, and a through hole 103 may be formed in the first half-shell 120.

[0052] In the embodiments disclosed herein, such as Figure 1 , Figure 4 and Figure 8 As shown, the first end 350 of the connector 300 can be slidably connected to the first housing 100 via the connecting structure 500 to adjust the length of the first end 350 outside the first housing 100. Different lengths of the first end 350 outside the first housing 100 result in different clamping spaces 640 formed by the headphone device. Different clamping spaces 640 can accommodate ears of different sizes, thereby improving the headphone device's ability to adapt to different ear sizes. For example, as... Figure 4 As shown, the first end 350 has a relatively short length outside the first housing 100, allowing the headphone device to fit smaller ears. Figure 1 As shown, the first end 350 has a relatively long length extending beyond the first housing 100, allowing the headphone device to accommodate larger ears. Figure 8 As shown, the first end 350 is the longest outside the first housing 100, where the headphone device can fit the largest size ear.

[0053] The first housing 100 can slide to at least one target position relative to the first end 350 of the connector 300 via the connecting structure 500. At the target position, the first housing 100 can rotate relative to the first end 350 to adjust the position of the first housing 100 relative to the second housing 200. By adjusting the position of the first housing 100 relative to the second housing 200, the position of the first housing 100 relative to the wearer's ear can be adjusted, thereby improving the headphone device's ability to adapt to different ear shapes and its ability to adapt to different usage scenarios.

[0054] For example, the wearer can adjust the position of the first shell 100 according to the shape of their own ears to achieve the best wearing condition for the wearer.

[0055] For example, by adjusting the position of the first housing 100 relative to the second housing 200, the position of the first housing 100 and the wearer's concha can be adjusted, thereby moving the sound-emitting hole 104 of the first housing 100 away from or closer to the wearer's ear canal to accommodate different usage scenarios. As an example, in a scenario where the wearer needs an in-ear headphone, the first housing 100 can be rotated so that the sound-emitting hole 104 is closer to the wearer's ear canal; in a scenario where the wearer needs an open-back headphone, the first housing 100 can be rotated so that the sound-emitting hole 104 is farther away from the wearer's ear canal.

[0056] For example, by adjusting the position of the first housing 100 relative to the second housing 200, the clamping gap 650 between the first housing 100 and the second housing 200 can be adjusted, thereby adjusting the wearing clamping force of the headphone device to accommodate different usage scenarios. As an example, in scenarios where the wearer requires a larger clamping force, the first housing 100 can be rotated closer to the second housing 200; in scenarios where the wearer requires a smaller clamping force, the first housing 100 can be rotated further away from the second housing 200. In one application, in scenarios with high exercise intensity such as running or skipping rope, the wearer can rotate the first housing 100 closer to the second housing 200 to increase the wearing clamping force and thus improve wearing stability; in scenarios with low exercise intensity such as sitting, walking, or lying down, the wearer can rotate the first housing 100 further away from the second housing 200 to reduce the wearing clamping force and thus improve wearing comfort.

[0057] The number of target positions is not limited. For example, the target positions can be all positions on the sliding path of the first housing 100 relative to the first end 350 of the connector 300; in other words, any position on the sliding path of the first housing 100 relative to the first end 350 of the connector 300 can be rotated. Alternatively, the target positions can be a portion of the sliding path of the first housing 100 relative to the first end 350 of the connector 300; in other words, a portion of the sliding path of the first housing 100 relative to the first end 350 of the connector 300 can be rotated, while the remaining positions on the sliding path of the first end 350 of the connector 300 cannot be rotated.

[0058] When the target position is a portion of the sliding path of the first housing 100 relative to the first end 350 of the connecting body 300, the target position can be one position, or at least two positions, at least three positions, etc. This disclosure does not limit this. For example, the first housing 100 can slide to at least two target positions relative to the first end 350 of the connecting body 300 via the connecting structure 500. At adjacent target positions, the range of angles that the first housing 100 can rotate relative to the first end 350 can be the same or different.

[0059] The method by which the first housing 100 can rotate relative to the first end 350 at the target position is not limited.

[0060] For example, the connecting structure 500 may include: a slide rail 510, which may be disposed in the first housing 100 and may be cylindrical; at least a portion of the first end 350 may be slidably located within the slide rail 510; at least a portion of the first end 350 may slide along the axial direction of the slide rail 510 and may rotate about the axial direction of the slide rail 510; here, the target position may be all positions of the first housing 100 relative to the sliding path of the first end 350 of the connecting body 300. Of course, in other examples, the slide rail 510 may also be located at the first end 350.

[0061] For example, the connecting structure 500 may include: a slide rail 510, which may be disposed in the first housing 100. The slide rail 510 may be cylindrical, and a portion of the slide rail 510 may be recessed along the axial direction to form a guide groove; at least a portion of the first end 350 is slidably located within the slide rail 510, and a guide protrusion may be provided on the outer side of the first end 350. The guide protrusion is inserted into the guide groove to prevent the first end 350 from rotating around the axis of the slide rail 510; here, the first housing 100 may also have at least one rotating groove; the rotating groove may be connected to the slide rail 510 and the guide groove respectively, and the rotating groove may be annular, semi-annular, etc.; when the guide protrusion slides along the slide rail 510 into the rotating groove, the guide protrusion can rotate within the rotating groove, thereby enabling at least a portion of the first end 350 to rotate around the axial direction of the slide rail 510; here, the position where the rotating groove is provided along the axial direction of the slide rail 510 is the target position, and the position where the rotating groove is not provided is a non-target position where rotation is not possible; the number of rotating grooves is not limited. For example, the number of rotating slots can be at least two, at least three, etc., spaced apart. Here, the target location is the portion of the rotating slot on the sliding path of the first housing 100 relative to the first end 350 of the connecting body 300. Of course, in other examples, the slide 510 can also be formed at the first end 350.

[0062] At the target position, the first housing 100 can rotate in one direction or in multiple directions relative to the first end 350 via the connecting structure 500. This disclosure does not limit this.

[0063] The sliding direction is the direction in which the first end 350 of the connector 300 and the first housing 100 slide relative to each other. For example, the sliding direction can be the length direction of the slide rail 510.

[0064] In some implementations of the embodiments of this disclosure, the first housing 100 can rotate in a first direction relative to the first end 350 at the target position via the connecting structure 500. By rotating the first housing 100 in the first direction at the target position, the position of the first housing 100 in the first direction can be adjusted, thereby adjusting the relative positional relationship between the first housing 100 and the second housing 200 in the first direction.

[0065] In this implementation, the first direction is not limited. For example, the first direction can be the direction in which the first housing 100 approaches or moves away from the second housing 200. By rotating the first housing 100 along the first direction, the clamping gap 650 and clamping force between the first housing 100 and the second housing 200 can be adjusted. As another example, the first housing 100 can have a sound-emitting hole 104 corresponding to the position of the sound-emitting component 410. The first direction can be the direction in which the sound-emitting hole 104 approaches or moves away from the wearer's ear canal. By rotating the first housing 100 along the first direction, the distance between the sound-emitting hole 104 and the wearer's ear canal can be adjusted.

[0066] The relationship between the first direction and the sliding direction is not limited. For example, the first direction can be the direction of rotation about the sliding direction. As an example, the first end 350 is slidably located within the slide 510 by means of the slide 510 and the guide groove, and the first housing 100 is rotated relative to the first end 350 of the connecting body 300 by means of the rotation groove; here, the rotation groove can be annular, and the direction in which the rotation groove is set is the first direction.

[0067] In some implementations of the embodiments of this disclosure, the first housing 100 can slide to at least two target positions relative to the first end 350 of the connector 300 via the connecting structure 500. At adjacent target positions, the first housing 100 can rotate at different angles relative to the first end 350, thereby improving the adaptability of the headphone device by allowing the first housing 100 to rotate at different target positions within a certain range of angles.

[0068] In this implementation, the range of angles at which the first housing 100 can rotate relative to the first end 350 at adjacent target positions is not limited. For example, adjacent target positions can be rotated via rotating slots, and the lengths and angles of the rotating slots corresponding to adjacent target positions are different.

[0069] In some implementations of the embodiments of this disclosure, the first housing 100 can slide to a first target position and a second target position relative to the first end 350 of the connecting body 300 via the connecting structure 500; at the first target position, the first end 350 has a first length outside the first housing 100, and the first housing 100 can rotate relative to the first end 350 within a first angle range; at the second target position, the first end 350 has a second length outside the first housing 100, and the first housing 100 can rotate relative to the first end 350 within a second angle range; the first length and the second length are different, and the first angle range and the second angle range can be different.

[0070] In this implementation, the first length can be greater than the second length, and the first angle range can be greater than the second angle range. The larger the value of the first length, the larger the clamping space 640 formed by the headphone device, the larger the ear size that the headphone device can adapt to, and the greater the possibility that the first shell 100 needs to be adjusted based on the wearer's ear.

[0071] In this implementation, the values ​​of the first angle range and the second angle range are not limited. For example, the first angle range can be 11 to 15 degrees, 13 to 15 degrees, 14 to 16 degrees, 15 to 20 degrees, etc. As another example, the second angle range can be 5 to 8 degrees, 5 to 7.5 degrees, 6.5 to 8.5 degrees, 8 to 11 degrees, etc.

[0072] As an example, the first target location can be... Figure 8 The corresponding position, the second target position can be Figure 1 Corresponding position; the headphone device may also have Figure 4 Corresponding position. For example... Figure 4 As shown, the length of the first end 350 outside the first housing 100 is minimal, or the first end 350 has no portion outside the first housing 100; in other words, the first end 350 is entirely within the first housing 100. Here, the clamping space 640 of the headphone device is minimal, and the headphone device can fit relatively small ears. Here, the clamping force between the first housing 100 and the second housing 200, and the orientation of the sound hole 104, can be relatively fixed, and the headphone device can be similar to conventional headphones that cannot be adjusted in size.

[0073] like Figure 1 As shown, the length of the first end 350 outside the first housing 100 can be a second length, and the first housing 100 can rotate relative to the first end 350 within a second angle range; here, the clamping space 640 of the headphone device is increased, and the headphone device can be adapted to relatively large ears. Here, the clamping force between the first housing 100 and the second housing 200, the orientation of the sound hole 104, etc., can be adjusted by rotating the first housing 100. Figure 8 As shown, the length of the first end 350 outside the first housing 100 can be a first length, and the first housing 100 can rotate relative to the first end 350 within a first angle range; here, the clamping space 640 of the headphone device is the largest, and the headphone device can fit the largest size ear. Here, the clamping force between the first housing 100 and the second housing 200, the orientation of the sound hole 104, etc., can be greatly adjusted by rotating the first housing 100.

[0074] As yet another example, the first target location can be Figure 1 The corresponding position, the second target position can be Figure 4 Corresponding position; the first target position can also be Figure 8 The corresponding position, the second target position can also be Figure 1 Corresponding position. Here, the clamping force between the first housing 100 and the second housing 200, the orientation of the sound-emitting hole 104, etc., can be adjusted by rotating the first housing 100. The rotation angle range of the first housing 100 is from... Figure 4 , Figures 1 to 8 The values ​​can be increased sequentially. Here, the angular difference between two adjacent target positions can be 3 degrees, 5 degrees, 7 degrees, etc.

[0075] Of course, in other examples, the range of rotation angle of the first housing 100 may remain constant at three adjacent target positions, or it may increase first and then decrease, etc. This disclosure does not limit this.

[0076] In some implementations of the embodiments of this disclosure, such as Figure 1 and Figure 3 As shown, the connection structure 500 may include a slide rail 510 and a first elastic member 530. The slide rail 510 may be formed in the first housing 100. At least a portion of the first end 350 may be slidably located within the slide rail 510. The first elastic member 530 may be disposed on the side of the first outer surface 351 of the first end 350 and abut against the first inner surface 514 of the slide rail 510, so that the second outer surface 352 of the first end 350, which is opposite to the first outer surface 351, contacts the second inner surface 515 of the slide rail 510. By having the first elastic member 530 and the second outer surface 352 contact the first inner surface 514 and the second inner surface 515 of the slide rail 510 respectively, a damping force can be provided for at least a portion of the first end 350 to slide within the slide rail 510, thereby improving the relative stability of the positional relationship between the first housing 100 and the first end 350.

[0077] In this implementation, under the action of external force, the first end 350 can overcome the damping force and slide along the slide rail 510; when the external force is removed, the first end 350 cannot slide along the slide rail 510 due to the damping force; thus, after the position of the first end 350 relative to the first housing 100 is adjusted, the damping force can keep the first end 350 and the first housing 100 in their current positions, thereby improving the shape stability of the headphone device.

[0078] Of course, in some other implementations, the connection structure 500 may not include the first elastic element 530. Here, at least a portion of the first end 350 may have friction with the slide 510. Here, the friction is a damping force. The friction can keep the first end 350 and the first housing 100 in their current positions, thereby improving the shape stability of the headphone device.

[0079] In this implementation, the shape of the slide 510 is not limited. For example, the slide 510 can be cylindrical, conical, etc.; here, the cross-section of the slide 510 can be circular. As an example, the slide 510 can be cylindrical, and here, the target position can be all positions on the sliding path of the first housing 100 relative to the first end 350 of the connecting body 300. As another example, the slide 510 can be cylindrical, with a guide groove and a rotation groove provided at the slide 510, and a guide protrusion provided on the first elastic member; the first housing 100 can be rotated by rotating the guide protrusion on the first elastic member within the rotation groove, and here, the target position is a partial position on the sliding path of the first housing 100 relative to the first end 350 of the connecting body 300. For another example, the cross-section of the slide 510 can be non-circular; here, since the first elastic member can deform, the rotation direction of the first housing 100 can be a direction in which a portion of the first housing 100 rotates toward or away from the second outer surface 352. As an example, the first inner surface 514 is provided with a groove, and the first elastic member is provided with a guide protrusion, which can slide in the groove; the first end 350 of the connector 300 can also rotate toward or away from the second outer surface 352.

[0080] In this implementation, the shapes of the first inner surface and the second inner surface are not limited. For example, the first inner surface can be a planar structure or a curved surface. Similarly, the second inner surface can be a planar structure or a curved surface. As an example, both the first and second inner surfaces can be planar; the first inner surface may include one plane, and the second inner surface may include multiple planes.

[0081] The slide rail 510 may have a first distance between the first inner surface 514 and the second inner surface 515, and the first end 350 may have a second distance between the first outer surface 351 and the second outer surface 352. The first distance minus the second distance can be a set gap, which can satisfy the rotation of the first end 350 within the range defined by the first inner surface 514 and the second inner surface 515. It should be noted that since the first elastic member 530 abuts against the first inner surface 514 and the second outer surface 352 abuts against the second inner surface 515, the damping force provided by the deformation force of the first elastic member 530 can also improve the stability of the relative positional relationship between the first housing 100 and the first end 350 without the action of external force; in other words, the first housing 100 and the first end 350 will not slide or rotate relative to each other without the action of external force. Under the action of external force, at least a portion of the first end 350 can slide or rotate within the slide rail 510. For example, at least a portion of the first end 350 can rotate toward or away from the first inner surface 514.

[0082] In some examples, such as Figure 3As shown, the first inner surface 514 can be a planar structure, and the second inner surface 515 can include a first region 5151 located near the opening 516 of the slide 510, a second region 5152 located away from the opening 516, and an arcuate region 5153 located between the first region 5151 and the second region 5152. The distance between the first region 5151 and the first inner surface 514 can be greater than the distance between the second region 5152 and the first inner surface 514. The second outer surface 352 of the first end 350 is used to abut against the arcuate region 5153 to enable the first end 350 to rotate relative to the first housing 100. During the sliding process, when the second outer surface 352 of the first end 350 abuts against the arc-shaped region 5153, the first end 350 can rotate relative to the first housing. During the rotation, the first end 350 rotates within the range defined by the first region 5151 and the second inner surface 515, with the arc-shaped region 5153 as the fulcrum. In other words, the first end 350 is similar to a seesaw, and the arc-shaped region 5153 is similar to the fulcrum of the seesaw. Under the action of external force, the first end 350 can rotate towards or away from the first region 5151 with the arc-shaped region 5153 as the fulcrum. During the sliding process, the first end 350 can slide within the space defined by the second region 5152 and the first inner surface 514; in other words, the first end 350 can slide along the first inner surface 514 based on the portion located between the second region 5152 and the first inner surface 514; during the sliding process, the first end 350 can be located near the first inner surface 514; when the first end 350 is located near the first inner surface 514, the first end 350 can rotate away from the first inner surface 514, such as... Figure 7 As shown; when the first end 350 is rotated to the side away from the first inner surface 514, the first end 350 can hardly slide, and the first end 350 can rotate towards the side closer to the first inner surface 514. When the first end 350 is rotated to the side closer to the first inner surface 514, as... Figure 3 As shown, the first end 350 can slide along the slide rail 510 to... Figure 5 or Figure 9 The location shown.

[0083] The first end 350 is inserted into the slide 510 through the opening 516 of the slide 510 and can slide within the slide 510. The longer the first end 350 is inserted into the slide 510, the shorter the length of the first end 350 outside the first housing 100.

[0084] like Figure 11As shown, the distance between the first region 5151 and the first inner surface 514 can gradually decrease in the direction away from the opening 516. The first region 5151 can be used to define the limit position of the rotation of the first end 350 relative to the first housing 100. By tilting the first region 5151, the contact area between the first end 350 and the first region 5151 can be increased, thereby improving the stability of the limiting position of the first region 5151. Of course, in other examples, the first region 5151 can also be non-tilted; or, the first region 5151 can also be an arc-shaped structure, etc. This disclosure does not limit this.

[0085] like Figure 5 As shown, the second region 5152 can be a planar structure, and the second region 5152 and the first inner surface 514 can be parallel. The second outer surface 352 of the first end 350 is used to limit the rotation of the first end 350 relative to the first housing by abutting against the second region 5152; in other words, as Figure 5 As shown, when the longer portion of the first end 350 is located between the first inner surface 514 and the second region 5152 of the planar structure, the first end 350 contacts the second region 5152 of the planar structure due to the action of the first elastic member 530, and the second region 5152 will limit the rotation of the first end 350; here, the first end 350 may not be able to rotate; or, in some examples, the first end 350 may have a small rotation angle due to the elasticity of the first elastic member 530.

[0086] like Figure 3 , Figure 7 and Figure 9 As shown, the first inner surface 514 can be used to define the limit position of the first end 350 relative to the first housing.

[0087] In this implementation, the slide 510 may also have a third inner surface and a fourth inner surface disposed opposite to each other; the first inner surface 514, the third inner surface, the second inner surface 515, and the fourth inner surface may be connected sequentially to define the slide 510. The shapes of the third inner surface and the fourth inner surface are not limited. For example, the third inner surface may be a planar structure or a curved surface structure, etc. As another example, the fourth surface may be a planar structure or a curved surface structure.

[0088] In some examples, at least a portion of the first end 350 may be unable to rotate toward or away from the third inner surface. Here, the third and fourth inner surfaces can be used to limit the rotation of at least a portion of the first end 350 toward or away from the third inner surface. In other examples, at least a portion of the first end 350 may rotate toward or away from the third inner surface; for example, a first elastic member 530 that abuts against the third inner surface may be provided on the outer surface of the first end 350. Alternatively, the distance between the third and fourth inner surfaces may be greater than the size of the first end 350, allowing the first end 350 to rotate toward or away from the third inner surface via a first elastic member 530. This disclosure does not limit this aspect.

[0089] In this implementation, the structure of the first elastic element 530 is not limited. For example, the first elastic element 530 can be an elastic column, an elastic ball, an elastic sheet, etc. This disclosure does not limit this. The material of the first elastic element 530 is not limited. For example, the material of the first elastic element 530 can include metals, polymers, etc.

[0090] Example 1: The first housing 100 has at least one recess on its first inner surface 514; the first elastic member 530 has a protrusion 531 for engaging with the recess; when the first housing 100 slides to a target position with the protrusion 531 located in at least one recess, the first housing 100 slides to a target position; under the action of an external force, the protrusion 531 can rotate within at least one recess, and when the external force is removed, the protrusion 531 cannot rotate within the recess due to the damping force, thereby improving the stability of the relative positional relationship between the first housing 100 and the first end 350.

[0091] In Example 1, when the protrusion 531 is located within the recess, a first width can be formed between the protrusion 531 and the second outer surface 352, and the first elastic member 530 can have a first deformation amount. When the protrusion 531 is located outside the recess, a second width can be formed between the protrusion 531 and the second outer surface 352, and the first elastic member 530 can have a second deformation amount. The first width can be greater than the second width, and the first deformation amount can be less than the second deformation amount. When the protrusion 531 is located within the recess, the first deformation amount can be relatively small, allowing the protrusion 531 to rotate within the recess under external force, thereby enabling the first housing 100 to rotate relative to the first end 350. When the protrusion 531 is located outside the recess, the second deformation amount can be relatively large, preventing the first housing 100 from rotating relative to the first end 350 under the same external force. Of course, in other examples, the first and second deformation amounts can be substantially the same, and the damping force can also be substantially the same whether the protrusion 531 is located within or outside the recess.

[0092] The first elastic element has already been described above in Example 1, and will not be repeated here.

[0093] As an example, the first elastic member 530 may include a first end 532 and a second end 533 spaced apart in the sliding direction; a protrusion 531 may be present between the first end 532 and the second end 533; the first end 532 and the first end 350 may be connected by means of bonding, snapping, welding or the like; the second end 533 may be movable in a direction away from the first end 532 to reduce the damping force provided by the first elastic member 530 for the first end 350 to slide in the slide rail 510.

[0094] Here, the first end 532 can be fixed by means of bonding, snap-fitting, welding, etc. The connecting portion 534 of the first elastic member 530 located between the first end 532 and the second end 533 can be suspended so that the first elastic member 530 can deform. A portion of the connecting portion 534 is provided to form a protrusion 531, and the second end 533 can be fixed in the direction away from the protrusion 531. For example, the first end 350 may be provided with a limiting step 353. One surface of the limiting step 353 is used to limit the movement of the second end 533 in the direction away from the protrusion 531, thereby enabling the second end 533 to be fixedly set in the direction away from the protrusion 531. The other surface of the limiting step 353 is used to limit the extreme position of the second end 533 moving towards the first end 532, thereby enabling the second end 533 to move in the direction away from the first end 532. Of course, when the second end 533 is not in contact with the other surface, the second end 533 can move in the direction close to the first end 532. By enabling the second end 533 to be moved in the direction away from the first end 532, the deformation of the first elastic member 530 can be adjusted, thereby adjusting the damping force provided by the first elastic member 530, so that the damping force provided by the first elastic member 530 is within a set range, thereby improving the operability of adjusting the relative positional relationship between the first housing 100 and the first end 350, and thus improving the customer experience of the headphone device.

[0095] Here, the structures of the first end 532, the second end 533, and the connecting portion 534 are not limited. For example, the first end 532, the second end 533, and the connecting portion 534 can all be strip-shaped structures, plate-shaped structures, etc. The first end 532 and the second end 533 can be located on the same side of the connecting portion 534, and the first end 532 and the protrusion 531 can be located on opposite sides of the connecting portion 534. As an example, such as Figure 14 and Figure 15As shown, the first elastic member 530 can be plate-shaped, the protrusion 531 can be column-shaped, and the included angle between the first end 532 and the connecting portion 534 can be greater than or equal to 90 degrees, 95 degrees, etc. The distance between the protrusion 531 and the first end 532 can be equal to the distance between the protrusion 531 and the second end 533.

[0096] Here, when the protrusion 531 is inside the recess, the protrusion 531 contacts the recess; when the protrusion 531 is outside the recess, the protrusion 531 abuts against the first inner surface 514. One surface of the limiting step 353 and the second end 533 can always be in contact, so that the deformation force of the first elastic member 530 can make the second outer surface 352 of the first end 350 contact the second inner surface 515 of the slide 510.

[0097] During the deformation of the first elastic element 530, the fixed first end 532 ensures the relative position of the first elastic element 530. The movement of the second end 533 away from the first end 532 allows for adaptive deformation of the first elastic element 530 while reducing the damping force provided by it. For example, when the protrusion 531 is outside the recess, the deformation of the first elastic element 530 is larger. Moving the second end 533 away from the first end 532 reduces the deformation force of the first elastic element 530, thus facilitating deformation under external forces. The first end 350 slides smoothly within the slide rail 510; when the protrusion 531 slides into the recess, the deformation of the first elastic member 530 decreases, and the second end 533 moves towards the first end 532, which increases the deformation force of the first elastic member 530 and improves the stability of the relative positional relationship between the first housing 100 and the first end 350; in case of accidental collision, the protrusion 531 rotates within the recess. Under relatively large external force, the protrusion 531 can rotate within the recess to achieve relative rotation between the first housing 100 and the first end 350.

[0098] In Example 1, the slide rail 510 may have a first distance between the first inner surface 514 and the second inner surface 515, and the first end 350 may have a second distance between the first outer surface 351 and the second outer surface 352. The first distance minus the second distance can be a set gap, which allows the first end 350 to rotate within the range defined by the first inner surface 514 and the second inner surface 515. It should be noted that since the protrusion 531 abuts against the first inner surface 514 and the second outer surface 352 abuts against the second inner surface 515, the damping force provided by the deformation force of the protrusion 531 can also improve the stability of the relative positional relationship between the first housing 100 and the first end 350 without external force; in other words, the first housing 100 and the first end 350 will not slide or rotate relative to each other without external force. Under external force, at least a portion of the first end 350 can slide or rotate within the slide rail 510.

[0099] Here, the first distance can be a fixed value or a non-fixed value. As an example, if the first inner surface 514 is a planar structure, and the second inner surface 515 includes a first region 5151 located near the opening 516 of the slide rail 510, a second region 5152 located away from the opening 516, and an arcuate region 5153 located between the first region 5151 and the second region 5152, the first distance between the first inner surface 514 and the second region 5152 can be minimized, the set gap at the second region 5152 can be minimized, and the value of the set gap at the second region 5152 is not limited. For example, the set gap at the second region 5152 can be 0.1mm to 0.2mm, 0.1mm to 0.15mm, 0.15mm to 0.25mm, etc. The set gap at the first region 5151 can be greater than 0.15mm, 0.25mm, 0.35mm, etc.

[0100] In Example 1, the shape of the protrusion is not limited. The shape of the recess is not limited. For example, the surface of the recess can be an arcuate surface, and the surface of the protrusion 531 can be an arcuate surface. The smoothness of the protrusion's rotation within the recess can be improved through the mating of the arcuate surfaces. Here, the rotation direction of the first housing 100 relative to the first end 350 can be a direction closer to or farther from the first inner surface 514. The rotation direction of the first housing 100 relative to the first end 350 can be one direction or multiple directions; as an example, the rotation direction of the first housing 100 relative to the first end 350 can include the first direction. For another example, the surface of the recess can be spherical, and the surface of the protrusion 531 can be spherical. The protrusion 531 can be used to rotate relative to the recess in at least two directions. The smoothness of the protrusion's rotation within the recess can be improved through the mating of the spherical surfaces. Here, the rotation direction of the first housing 100 relative to the first end 350 can be a direction closer to or farther from the first inner surface 514. This rotation direction can include a first direction. For example, the surface of the recess can be a cylindrical surface, and the surface of the protrusion 531 can be a cylindrical surface. The protrusion 531 can be used to rotate relative to the recess along a first direction; here, the first direction can be a direction of rotation about the axis of the cylindrical surface.

[0101] As an example, the surface of the recessed portion can be cylindrical, and the surface of the protrusion 531 can be cylindrical. The axis of the cylindrical surface can be perpendicular to the length direction of the slide 510. At the target position, the first end 350 can rotate toward or away from the first inner surface 514, and the first housing 100 can rotate relative to the first end 350 in a first direction. Thus, when the protrusion 531 is located in the recessed portion, the first housing 100 can rotate toward or away from the second housing 200, or the sound hole 104 of the first housing 100 can rotate toward or towards the wearer's ear canal.

[0102] In Example 1, the number of recesses is not limited. The number of recesses can be one, or at least two, at least three, etc.

[0103] For example, the first housing 100 may have at least two spaced recesses on its first inner surface 514 along the sliding direction; when the first housing 100 slides to the point where the protrusion 531 is located in at least two different recesses, the first housing 100 slides to different target positions and the first housing 100 can rotate at different angles relative to the first end 350.

[0104] In this example, the implementation of different rotational angle ranges of the first housing 100 relative to the first end 350 is not limited. As an example, the shape and depth of the recesses are different, and different rotational angle ranges are achieved by recesses of different shapes and depths. In some examples, the protrusion 531 may be spherical, at least two recesses may be spherical, and at least two recesses may have different depths to make the rotational angle ranges different; or, at least two recesses may be columnar and spherical, and columnar and spherical recesses can make the rotational angle ranges different. In yet another example, the protrusion 531 may be columnar, at least two recesses may be columnar, and at least two recesses may have different depths to make the rotational angle ranges different.

[0105] In Example 1, the first housing 100 may have a first recess 511 and a second recess 512 spaced apart along the sliding direction on the first inner surface 514; when the protrusion 531 is located in the first recess 511, the first housing 100 slides to the first target position and the first housing 100 can rotate relative to the first end 350 within a first angle range; when the protrusion 531 is located in the second recess 512, the first housing 100 slides to the second target position and the first housing 100 can rotate relative to the first end 350 within a second angle range.

[0106] When the protrusion 531 is located in the first recess 511, the first end 350 may have a first length outside the first housing 100; when the protrusion 531 is located in the second recess 512, the first end 350 has a second length outside the first housing 100; the first length and the second length have been described in the above embodiments, and will not be repeated here.

[0107] As an example, the distance between the first recess 511 and the opening 516 of the slide 510 can be less than the distance between the second recess 512 and the opening 516 of the slide 510; the first length can be greater than the second length, and the first angle range can be greater than the second angle range. The first angle range and the second angle range have been described in the above embodiments, and will not be repeated here.

[0108] The first angle range being greater than the second angle range can be achieved by varying the shape and depth of the recess.

[0109] In Example 1, the first housing 100 may also have a third recess 513 on the first inner surface 514, and the distance between the second recess 512 and the opening 516 of the slide 510 may be less than the distance between the third recess 513 and the opening 516 of the slide 510.

[0110] When the protrusion 531 is located in the third recess 513, the first housing 100 may not be able to rotate relative to the first end 350; or, the first housing 100 may be able to rotate relative to the first end 350 within a third angle range, which may be smaller than the second angle range. The value of the third angle range is not limited. For example, the third angle range may be 1 degree to 3 degrees, 2 degrees to 3 degrees, 1 degree to 2 degrees, etc.

[0111] In some examples, the first inner surface 514 may be a planar structure, and the second inner surface 515 may include a first region 5151 located on the side near the opening 516 of the slide 510, a second region 5152 located on the side away from the opening 516, and an arcuate region 5153 located between the first region 5151 and the second region 5152.

[0112] like Figure 9 and Figure 11 As shown, when the protrusion 531 is located in the first recess 511, the second outer surface 352 of the first end 350 and the second region 5152 can have a first contact length in the sliding direction. The first contact length is relatively short, and the second outer surface 352 of the first end 350 can abut against the arcuate region 5153 and rotate. The first inner surface 514 and the first region 5151 can be used to limit the extreme position of the rotation of the first end 350 relative to the first housing 100.

[0113] Here, the first end 350 is capable of rotating around the arc-shaped region 5153 as a fulcrum. The contact between the first inner surface 514 and the first outer surface 351 of the first end 350 defines the limit position of rotation of the first end 350 towards the first inner surface 514, and the contact between the first region 5151 and the second outer surface 352 of the first end 350 defines the limit position of rotation of the first end 350 away from the first inner surface 514. Of course, in other examples, the contact between the second outer surface 352 of the first end 350 and the second region 5152 can also define the limit position of rotation of the first end 350 towards the first inner surface 514, and the contact between the first outer surface 351 of the first end 350 and the first inner surface 514 can define the limit position of rotation of the first end 350 away from the first inner surface 514. This disclosure does not limit this.

[0114] like Figure 3 and Figure 7As shown, when the protrusion 531 is located in the second recess 512, the second outer surface 352 of the first end 350 and the second region 5152 can have a second contact length in the sliding direction. The second contact length can be greater than the first contact length. In other words, the contact length between the first end 350 and the second region 5152 is relatively large. The second outer surface 352 of the first end 350 can abut against the arc-shaped region 5153 and rotate. The first inner surface 514 located in different regions on both sides of the second recess 512 can be used to limit the extreme position of the rotation of the first end 350 relative to the first housing. Here, the second region 5152 can limit the extreme position of the rotation of the first end 350 relative to the first housing.

[0115] Here, the first end 350 can rotate around the arc-shaped region 5153 as a fulcrum. The limit position of the first end 350's rotation towards the first inner surface 514 can be defined by the contact between the region of the first inner surface 514 near the opening 516 and the region of the first outer surface 351 near the opening 516. The limit position of the first end 350's rotation away from the first inner surface 514 can be defined by the contact between the region of the first inner surface 514 away from the opening 516 and the region of the first outer surface 351 away from the opening 516. Here, the regions of the first inner surface 514 near the opening 516 and away from the opening 516 are located on both sides of the second recess 512, and the regions of the first outer surface 351 near the opening 516 and away from the opening 516 are located on both sides of the protrusion 531. Of course, in other examples, the extreme position of rotation of the first end 350 toward the first inner surface 514 can also be defined by the contact between the second outer surface 352 of the first end 350 and the second region 5152, and the extreme position of rotation of the first end 350 away from the first inner surface 514 can also be defined by the contact between the second outer surface 352 of the first end 350 and the first region 5151. This disclosure does not limit this.

[0116] like Figure 5 As shown, when the protrusion 531 is located in the third recess 513, the second outer surface 352 of the first end 350 and the second region 5152 can have a third contact length in the sliding direction, and the third contact length can be greater than the second contact length; in other words, the contact length between the first end 350 and the second region 5152 is the largest. Here, due to the limiting effect of the second region 5152, the first housing 100 may not be able to rotate relative to the first end 350; or, the first housing 100 may be able to rotate relative to the first end 350 within a third angle range.

[0117] In some examples, when the protrusion 531 is located in the third recess 513, the first housing 100 cannot rotate relative to the first end 350. By positioning the protrusion 531 in the third recess 513, the stability of the relative positional relationship between the first housing 100 and the first end 350 can be improved. For example, when shipping the headphone device from the factory and when the user is packing it up, the headphone device can be positioned with the protrusion 531 in the third recess 513. This relatively small size facilitates packing and transportation while preventing the first housing 100 from rotating relative to the first end 350 during movement and packing.

[0118] Here, the second region 5152 can be a planar structure, and the second region 5152 and the first inner surface 514 can be parallel or not parallel. This disclosure does not limit this.

[0119] Here, the first region 5151 can be a planar structure, and the distance between the first region 5151 and the first inner surface 514 can gradually decrease in the direction away from the opening 516.

[0120] It is important to note that Figure 5 yes Figure 4 Cross-sectional view, Figure 7 yes Figure 6 Cross-sectional view, Figure 9 yes Figure 8 Cross-sectional view, Figure 11 yes Figure 10 A cross-sectional view; the cutting position can be referenced. Figure 2 The CC section line in the diagram is not shown in this disclosure. Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 11 and Figure 13 In the case where the protrusion 531 is located inside the recess, the protrusion 531 is in contact with the surface of the recess. The protrusion 531 and the recess are shown in the figure as schematic relative positions.

[0121] In some examples, the distance between two adjacent recesses may be the same or different. This disclosure does not limit this. For example, the distance between two adjacent recesses may be the same, and the distance between two adjacent recesses may be 1.4 mm to 5 mm, 1.5 mm to 5 mm, 3 mm to 5 mm, 1 mm to 1.5 mm, 0.5 mm to 2 mm, etc.

[0122] In some examples, the distance between the first recess 511 and the third recess 513 can be 3mm to 5mm, 5mm to 8mm, 5mm to 8mm, etc.

[0123] In Example 1, the protrusion 531 can produce a clicking sound or change in damping force when it moves from outside the recess to inside the recess. This change in sound and damping force serves as a notification to the user that the relative position between the first housing 100 and the first end 350 is relatively stable, allowing the user to confirm that the first end 350 has slid to a relatively stable position. The first end 350 can slide to a target position, for example, when the protrusion 531 is located within the first recess 511 or the second recess 512. Alternatively, the first end 350 can slide to a non-target position, for example, when the protrusion 531 is located within the third recess 513.

[0124] It should be noted that the first recess 511, the second recess 512, and the third recess 513 are merely examples. For instance, in some other examples, the number of recesses may be at least four, with at least two of the four recesses corresponding to the target position, where the first housing 100 and the first end 350 can rotate relative to each other; or at least two of the four recesses may correspond to non-target positions, where the first housing 100 and the first end 350 cannot rotate relative to each other.

[0125] In this implementation, the headphone device may further include a limiting groove 710 and a limiting protrusion 720. The limiting groove 710 may be provided along the sliding direction of the slide rail 510, and the limiting protrusion 720 may be located within the limiting groove 710. The limiting protrusion 720 is used to contact the two side walls of the limiting groove 710 in the sliding direction to limit the extreme position of the relative sliding between the first end 350 and the first housing 100. During the relative sliding process between the first end 350 and the first housing 100, the limiting protrusion 720 is within the limiting groove 710. When the limiting protrusion 720 contacts one of the two side walls of the limiting groove 710, the first end 350 and the first housing 100 slide relative to each other to the extreme position. Through the cooperation of the limiting groove 710 and the limiting protrusion 720, the first end 350 can be prevented from dislodging from the slide rail 510.

[0126] Here, one of the limiting groove 710 and the limiting protrusion 720 can be disposed at the first end 350, and the other of the limiting groove 710 and the limiting protrusion 720 can be disposed at the first housing 100. As an example, Figure 12 As shown, the limiting groove 710 can be set at the first end 350, and the limiting protrusion 720 can be set at the first housing 100.

[0127] Here, when the first housing 100 has at least two spaced recesses on its first inner surface 514 along the sliding direction, the recesses at both ends of the at least two recesses can correspond to the extreme sliding positions of the first end 350 and the first housing 100 relative to each other. For example, when the at least two recesses include a first recess 511, a second recess 512, and a third recess 513, the first recess 511 and the third recess 513 can correspond to the extreme sliding positions of the first end 350 and the first housing 100 relative to each other. In other words, when the first end 350 and the first housing 100 slide relative to each other to the first extreme position, the protrusion 531 is located in the first recess 511; when the first end 350 and the first housing 100 slide relative to each other to the second extreme position, the protrusion 531 is located in the third recess 513.

[0128] The relative sliding distance between the first end 350 and the first housing 100 is not limited. For example, the relative sliding distance between the first end 350 and the first housing 100 can be 3mm to 5mm, 3mm to 8mm, 8mm to 10mm, etc. This disclosure does not limit this distance.

[0129] In this implementation, Figure 12 As shown, the end face 354 and the first outer surface 351 at the end of the first end 350 can be connected by an arc surface. Connecting the end face 354 and the first outer surface 351 at the end of the first end 350 by an arc surface can prevent the end of the first end 350 from limiting the range of the relative rotation angle between the first end 350 and the first housing 100; in other words, connecting the end face 354 and the first outer surface 351 at the end of the first end 350 by an arc surface can increase the range of the relative rotation angle between the first end 350 and the first housing 100. Of course, in other examples, the end face 354 and the first outer surface 351 at the end of the first end 350 can also be connected by a plane. As an example, the end face 354 and the first outer surface 351 at the end of the first end 350 can be connected by a right angle.

[0130] In some implementations of the embodiments of this disclosure, such as Figure 13 As shown, the headphone device may also include a connecting cable 440, a portion of which is located within the connector 300. One end of the connecting cable 440 can pass through the second end 360 of the connector 300 and connect to the circuit board 420, while the other end of the connecting cable 440 can pass through the first end 350 of the connector 300 and connect to the sound-generating component 410.

[0131] In some implementations of the embodiments of this disclosure, such as Figure 1 and Figure 2As shown, the headphone device may include an operation button 620, a charging unit 630, and a power supply 430. The operation button 620, charging unit 630, and power supply 430 may be disposed in the second housing 200. The operation button 620 can be used to control the headphone device. The charging unit 630 can be used to charge the power supply 430, and the power supply 430 can be used to supply power to the headphone device.

[0132] The second housing 200 may have a sound pickup hole 201, which can be used to pick up sound.

[0133] The headphone device of this disclosure, through a dual adjustment mechanism of relative rotation and relative sliding between the first housing 100 and the first end 350, enables the headphone device to adapt to the ear structure of more than 90% of people, especially solving the fitting problem for users with deep or shallow conchae when wearing traditional headphones. Compared with traditional headphones, the fit of the headphone device of this disclosure is improved by about 40%.

[0134] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
