[0044] The present invention provides an earphone for wireless audio transmission and playback.

[0045] The present invention provides a headset, such as Figure 1 As shown, the earphone includes a shell 1 and an ear support 2, the shell 1 is provided with a mounting portion and a first limiting portion, the first limiting portion is provided at the mounting portion; the ear support 2 includes a wearing portion 21 and a connecting portion 22 provided at one end of the wearing portion 21, the connecting portion is rotatably provided at the mounting portion, and the connecting portion is provided with a second limiting portion; wherein, the earphone has an assembly state in which the first limiting portion is engaged with the second limiting portion, and a disassembly state in which the first limiting portion is disengaged from the second limiting portion; the connecting portion rotates relative to the mounting portion to switch the earphone between the assembly state and the disassembly state.

[0046] In this embodiment, the shell 1 has a cavity 1a, which is used to accommodate sound units such as dynamic units and moving iron units. The shell 1 may have an extension portion for extending into the human ear canal. A detachable earmuff may be provided at the end of the extension portion so that the earphone can be adapted to the ear canals of different users, thereby improving the comfort of the earphone when worn.

[0047] The mounting portion is used to mount and fix the ear support 2, and the mounting portion may be a partial structure of the housing 1, or a boss structure disposed on the outer wall 11 of the housing 1. A first limiting portion is disposed on the mounting portion, and the first limiting portion is used to engage with a second limiting portion on the ear support 2 to achieve mounting and fixing of the ear support on the housing.

[0048] The ear support 2 is used to make the earphone fixed to the human ear. The wearing part 21 of the ear support 2 can be used to cooperate with the concha groove and the concha cymbidium of the human ear to improve the stability of the earphone when it is worn on the human ear, and avoid the problem that the earphone is easy to slip when the user wears the earphone for exercise. The connecting part 22 of the ear support 2 is used to engage with the mounting part of the shell 1, so that the ear support 2 as a whole can be more conveniently installed on the shell 1 of the earphone or removed from the shell 1 of the earphone, and the convenience of disassembly and assembly of the ear support 2 is improved. The wearing part 21 of the ear support 2 can be made of soft materials such as silica gel, so that the wearing part 21 has a certain elasticity and can produce a certain deformation, so that the wearing part 21 can be adapted to the ears of different users, and when the wearing part 21 contacts the human ear, the wearing part 21 is not easy to scratch the human ear, which is conducive to improving the wearing experience of the user. The connecting part 22 of the ear support 2 can be made of hard materials such as plastic, so that the connecting part 22 is not easy to deform and loosen from the mounting part, so as to improve the connection stability between the connecting part 22 and the mounting part. The wearing portion 21 and the connecting portion 22 of the ear support 2 are an integrally formed structure, so as to save processing steps and procedures of the ear support 2, reduce the processing cost of the ear support 2, and improve the structural strength of the ear support 2. The connecting portion 22 can be rotatably connected to the mounting portion of the housing 1 by means of hole-shaft matching, etc., and a second limiting portion is provided on the connecting portion 22, and the second limiting portion can be integrally formed with the connecting portion 22, and the second limiting portion can be snap-fitted with the first limiting portion on the mounting portion by means of snap-fitting and snap-fitting.

[0049] The technical solution of the present invention is to provide a mounting portion and a first limiting portion on the housing 1 of the earphone, and to provide a second limiting portion on the connecting portion of the ear support, so that the connecting portion is rotatably connected with the mounting portion. When the connecting portion rotates relative to the mounting portion, the first limiting portion and the second limiting portion can be engaged to achieve assembly and fixation of the ear support 2 on the housing 1; or the first limiting portion and the second limiting portion can be disengaged to achieve disassembly of the ear support 2 on the housing 1. In this way, by rotating the ear support 2 so that the ear support 2 rotates relative to the mounting portion, the assembly or disassembly of the ear support 2 on the housing 1 of the earphone can be achieved accordingly, which facilitates the assembly and disassembly of the ear support 2.

[0050] The assembly and disassembly of the ear support 2 and the housing 1 in the above-mentioned embodiment of the present invention can be achieved in various ways, which are described below by taking the first embodiment and the second embodiment as examples:

[0051] First embodiment:

[0052] Combination Figure 2 , Figure 3 as well as Figure 4As shown, the mounting portion is a partial structure of the shell 1, and the mounting portion has an inner wall 12 facing the cavity 1a and an outer wall 11 facing away from the cavity 1a, the outer wall 11 is provided with a mounting hole 11a connected to the cavity 1a, the first limiting portion is a clamping hole 12a provided on the inner wall 12; the second limiting portion is a clamping protrusion 2221 provided on the end of the connecting portion 22 away from the wearing portion 21; when the earphone is in an assembled state, the end of the connecting portion 22 away from the wearing portion 21 passes through the mounting hole 11a and extends into the cavity 1a, the clamping protrusion 2221 is clamped in the clamping hole 12a, and the connecting portion 22 is abutted against the outer wall 11 for limiting.

[0053] In this embodiment, the outer wall 11 and the inner wall 12 of the mounting portion may be arranged in a plane, the outer wall 11 of the mounting portion may partially protrude from the outer wall of the shell 1 , and the inner wall 12 of the mounting portion may also partially protrude from the inner wall of the shell 1 .

[0054] The mounting hole 11a is set through the outer wall 11 and the inner wall 12 of the mounting part, and the mounting hole 11a is a through hole 1b structure, which is connected with the cavity 1a. The mounting hole 11a allows the connecting part 22 to pass through, so that one end of the connecting part 22 can extend into the cavity 1a, and is engaged with the clamping hole 12a on the inner wall 12 of the mounting part through the clamping protrusion 2221, so as to realize the detachable connection between the connecting part 22 and the mounting part, and facilitate the detachable installation of the ear support 2 on the earphone housing 1.

[0055] Optionally, the connecting portion 22 includes a first connecting segment 221 and a second connecting segment 222; the two ends of the first connecting segment 221 are respectively connected to the second connecting segment 222 and the wearing portion 21, and the extension direction of the first connecting segment 221 forms an angle with the extension direction of the second connecting segment 222; the latching protrusion 2221 is arranged on the side of the second connecting segment 222 facing the wearing portion 21; when the earphone is in an assembled state, the first connecting segment 221 is partially limited to the mounting hole 11a, and the second connecting segment 222 is located in the cavity 1a.

[0056] In this embodiment, part of the structure of the connecting portion 22 is connected to the wearing portion 21, and a first connecting section 221 is provided at the connection between the connecting portion 22 and the wearing portion 21, and the second connecting section 222 is connected to the end of the first connecting section 221 away from the wearing portion 21, and is arranged at an angle other than 0 degrees and 180 degrees with the first connecting section 221, for example, the extension direction of the first connecting section 221 and the second connecting section 222 is arranged at 90 degrees. In this way, when the first connecting section 221 passes through the mounting hole 11a and extends into the cavity 1a, the second connecting section 222 can extend parallel to the inner wall 12 of the mounting portion, so that the clamping protrusion 2221 on the second connecting section 222 can be clamped with the clamping hole 12a on the inner wall 12 of the mounting portion, thereby realizing the clamping fit between the connecting portion 22 and the clamping hole 12a.

[0057] Optionally, the mounting hole 11a is a bar-shaped hole, and the length of the mounting hole 11a is greater than or equal to the length of the second connecting section 222 ; when the earphone is in an assembled state, an extension direction of the mounting hole 11a forms an angle with an extension direction of the second connecting section 222 .

[0058] In this embodiment, if Figure 3 As shown, the connection between the connecting portion 22 and the mounting portion is slidably abutted against the outer wall 11 of the mounting portion, and the second connecting section 222 can extend parallel to the mounting hole 11a into the cavity 1a, and the first connecting section 221 partially passes through the mounting hole 11a. Figure 4 As shown, the first connecting section 221 and the second connecting section 222 are rotated by rotating the wearing part 21, so that the locking protrusion 2221 on the second connecting section 222 slides along the inner wall 12 of the mounting part to form an arc track, until the locking protrusion 2221 moves to the upper part of the locking hole 12a, and the locking protrusion 2221 loses contact with the inner wall 12 of the mounting part and is locked into the locking hole 12a, thereby achieving the fixation of the connecting part 22 and the wearing part 21. A first chamfer may be provided at the opening of the locking hole 12a, and a second chamfer may be provided at the end of the locking protrusion 2221 away from the second connecting section 222. By using the cooperation of the first chamfer and the second chamfer, the locking protrusion 2221 can be smoothly locked into or removed from the locking hole 12a when the wearing part 21 is rotated, thereby achieving the installation, fixation and removal of the ear support 2 on the housing 1.

[0059] Optionally, the inner wall 12 is provided with an inclined surface 121 extending toward the mounting hole 11 a , the inclined surface 121 is connected to the hole wall of the mounting hole 11 a , and the inclined surface 121 is located between the mounting hole 11 a and the clamping hole 12 a .

[0060] In this embodiment, if Figure 3 As shown, when the second connecting section 222 passes through the bar-shaped mounting hole 11a in parallel, the locking protrusion 2221 on the second connecting section 222 will slide along the surface of the inclined surface 121 to the inner wall 12 of the mounting portion. The setting of the inclined surface 121 prevents the locking protrusion 2221 from being stopped by the side wall of the mounting hole 11a, and can slide more smoothly from the mounting hole 11a along the side wall of the mounting portion to the locking hole 12a, thereby achieving smooth locking fit between the locking protrusion 2221 and the locking hole 12a. In addition, when the wearing portion 21 is rotated to drive the locking protrusion 2221 to slip off the locking hole 12a, the locking protrusion 2221 can also slide along the inner wall 12 of the mounting portion to the inclined surface 121, and move out to the outside of the mounting hole 11a along the inclined surface 121, so that the ear support 2 can be easily disassembled from the housing 1 under the guidance of the inclined surface 121.

[0061] Optionally, the inner wall 12 is provided with a guide groove (not shown), the guide groove is connected to the mounting hole 11a and the clamping hole 12a, and when the earphone is switched between the assembled state and the disassembled state, the clamping protrusion 2221 moves along the guide groove.

[0062] In this embodiment, the guide groove is an arc groove, and the guide groove is used to guide the movement of the clamping protrusion 2221. When the second connecting section 222 passes through the mounting hole 11a and extends into the cavity 1a, and the first connecting section 221 partially passes through the mounting hole 11a, the forward rotation of the wearing portion 21 drives the first connecting section 221 and the second connecting section 222 to rotate, and the clamping protrusion 2221 will move along the guide groove toward the clamping hole 12a with the second connecting section 222. When the wearing portion 21 is rotated in the reverse direction, the clamping protrusion 2221 can move along the guide groove toward the mounting hole 11a accordingly. When the clamping protrusion 2221 moves along the guide groove, the clamping protrusion 2221 is at least partially accommodated and limited in the guide groove. In this way, by restricting the movable range of the clamping protrusion 2221 through the guide groove, the movement of the clamping protrusion 2221 can be guided, so that the clamping protrusion 2221 can move more stably between the clamping hole 12a and the mounting hole 11a, thereby ensuring the reliability of the ear support 2 during assembly and disassembly on the shell 1. In addition, the groove wall of the guide groove can be provided with a smooth layer made of a low friction coefficient material such as metal and steel to reduce the friction resistance when the protrusion 2221 slides along the guide groove and improve the smoothness of the movement of the protrusion 2221 along the guide groove.

[0063] Second embodiment:

[0064] Combination Figure 5 , Figure 6 as well as Figure 7 As shown, the mounting portion is a mounting groove 1d provided on the outer wall 11 of the shell 1, and the first limiting portion includes two first blocks 13 provided on the side wall of the mounting groove 1d, and the two first blocks 13 are arranged at intervals along the circumferential direction of the side wall of the mounting groove 1d, and a limited space 1e is formed between the two first blocks 13 and the bottom wall of the mounting groove 1d; the second limiting portion includes two second blocks 224 provided on the outer peripheral wall of the connecting portion, each second block 224 includes abutting portions 2241 and a stopping portion 2242, the two abutting portions 2241 are arranged in parallel along the circumferential direction of the outer peripheral wall of the connecting portion 22, and the two stopping portions 2242 are respectively provided at one end of the two abutting portions 2241 that are close to each other; when the earphone is in an assembled state, each abutting portion 2241 is limited in the limiting space 1e and abuts against a first block 13; each stopping portion 2242 is located between the two first blocks 13, and abuts against one end of a first block 13 for limiting.

[0065] In this embodiment, the mounting groove 1d is provided on the outer wall 11 of the housing 1, and can be a circular groove that is easy to process. The two first stoppers 13 can be integrally formed with the housing 1, and the two first stoppers 13 can be adjacent to the notch of the mounting groove 1d and can be arranged opposite to each other; the two first stoppers 13 are spaced apart from each other, and each first stopper 13 is spaced apart from the bottom wall of the mounting groove 1d, and the two first stoppers 13 can be arranged coplanarly, so that a uniformly high limiting space 1e is formed between the two first stoppers 13 and the bottom wall of the mounting groove 1d, and the height of the limiting space 1e is the distance between the first stopper 13 and the bottom wall of the mounting groove 1d. The two first stoppers 13 can be arc-shaped structures, and they both extend along the circumference of the side wall of the mounting groove 1d.

[0066] The connecting portion 22 may be a block-shaped or columnar structure, and its cross-sectional shape may be a circle matching the cross-sectional shape of the mounting groove 1d, and the two second stoppers 224 may be arc-shaped structures, and they both extend along the circumference of the outer wall 11 of the connecting portion 22. The two second stoppers 224 may be coplanarly arranged so that the spacing between the two second stoppers 224 and the end surface of the connecting portion 22 that is away from the wearing portion 21 is equal, so that when the end surface of the connecting portion 22 that is away from the wearing portion 21 abuts against the bottom wall of the mounting groove 1d, the two second stoppers 224 may be at least partially located in the limiting space 1e at the same time.

[0067] When the ear support 2 and the shell 1 in this embodiment are assembled, the connecting portion 22 extends into the mounting groove 1d and elastically abuts against the bottom wall of the mounting groove 1d, and the connecting portion 22 is pushed toward the bottom wall of the mounting groove 1d, so that the two second blocks 224 pass through the gap between the two blocks and enter the limiting space 1e. The stopping portion 2242 and the abutting portion 2241 of at least one block are completely located in the limiting space 1e. Rotate the wearing portion 21 to make the outer peripheral wall of the connecting portion 22 slide along the inner peripheral wall of the mounting groove 1d, and the two second stops 224 move relative to the two first stops 13 in the limiting space 1e until the stop portions 2242 of the two second stops 224 are again located between the two first stop portions 2242. Under the elastic cooperation between the bottom wall of the mounting groove 1d and the connecting portion 22, the stop portions 2242 of the two second stops 224 move away from the bottom wall of the mounting groove 1d and are at least partially located between the two first stops 13. At this time, the abutting portions 2241 of the two second stops 224 are both located in the limiting space 1e, and the stop portions 2242 of the two second stops 224 abut against the side walls of the two first stops 13. The two second stop portions 2242 are clamped with the two first stop portions 2242, and the ear support 2 is clamped and fixed on the shell 1.

[0068] Optionally, the earphone further comprises an elastic member 3 arranged on the bottom wall of the mounting groove 1d; in the assembled state, the side of the connecting portion 22 facing the bottom wall of the mounting groove 1d abuts against the elastic member 3, and the elastic member 3 is in a compressed state.

[0069] In this embodiment, when the connecting portion 22 is pushed into the installation groove 1d, the installation portion will squeeze the elastic member 3, causing the elastic member 3 to undergo elastic deformation and enter a compressed state. At the same time, the end of the installation portion away from the wearing portion 21 will move close to the bottom wall of the installation groove 1d, so that the abutting portions 2241 of the two second stops 224 can pass through between the two first stops 13 and enter the limiting space 1e. At this time, the wearing portion 21 can be rotated to drive the connecting portion 22 and the two second stops 224 to rotate, so that the two second stops 224 move relative to the two first stops 13 in the limiting space 1e until the two second stops 224 When the stop portion 2242 is again located between the two first stop portions 2242, the elastic member 3 pushes the connecting portion 22 to drive the stop portions 2242 of the two second stops 224 to move away from the bottom wall of the mounting groove 1d, and the abutting portions 2241 of the two second stops 224 are both located in the limiting space 1e, and the stop portions 2242 of the two second stops 224 extend between the two first stops 13 and abut against the side walls of the two first stops 13 respectively, and the two second stop portions 2242 are clamped with the two first stop portions 2242, the connecting portion 22 is fixed in the mounting groove 1d, and the ear support 2 is clamped and fixed on the shell 1. Among them, the elastic part 3 includes but is not limited to a soft rubber block or a bent metal spring sheet. The bottom wall of the installation groove 1d can be provided with an assembly groove 1d1 to accommodate and limit part of the elastic part 3 through the assembly groove 1d1. The elastic part 3 can also be connected and fixed to the bottom wall of the assembly groove 1d1 by bonding, plugging, etc., so as to improve the reliability of the installation and fixation of the elastic part 3.

[0070] Optionally, further combining Figure 8 As shown, the heights of the two stopper portions 2242 are defined as H1 and H2 respectively, and the distance between each first stopper 13 and the bottom wall of the mounting groove 1d is defined as D, D

[0071] ​In this embodiment, the distances between the two first stops 13 and the bottom wall of the mounting groove 1d are equal. By making the height H1 of one stop portion 2242 greater than the distance D between each first stop block 13 and the bottom wall of the mounting groove 1d, and making the height H2 of the other stop portion less than the distance D between each first stop block 13 and the bottom wall of the mounting groove 1d, when the mounting portion is assembled in the mounting groove 1d, the stop portion 2242 with a height of H1 will not enter the limiting space 1e, but can only be located between the two first stops 13. Therefore, the stop portion 2242 with a height of H1 will always play a stopping and limiting role for the second stop block 224 during the connection and rotation. When the connecting portion 22 rotates clockwise or counterclockwise along the circumferential direction of the inner wall of the mounting groove 1d, the stop portion 2242 with a height of H1 is always located between the two second stops 224, thereby limiting the rotation angle of the connecting portion 22 and preventing the connecting portion 22 from rotating at an excessively large angle, so that the connecting portion 22 can be assembled in the mounting groove 1d under a small angle rotation operation. When the mounting portion is assembled in the mounting groove 1d, the stop portion 2242 with a height of H2 can completely enter the limiting space 1e and rotate with the connecting portion 22 in the limiting space 1e until the stop portion 2242 with a height of H2 rotates between the two first blocks 13, and the elastic member 3 pushes the connecting portion 22 to drive the stop portion 2242 of the two second blocks 224 to move away from the bottom wall of the mounting groove 1d, and the stop portion 2242 with a height of H2 will extend between the two first blocks 13, and respectively abut against the side wall of a first block 13 for limiting position. At this time, the stop portion 2242 with a height of H1 and the stop portion 2242 with a height of H2 respectively abut against the two first stop portions 2242 for limiting position, and the connecting portion 22 is fixed in the mounting groove 1d, and the ear support 2 is clamped and fixed on the shell 1.
