The second connection cover 41 is used for shielding a side of the main housing 20 away from the horn assembly 30, and the expansion module 42 is fixedly mounted on a side of the second connection cover 41 facing the main housing 20. The second connection cover 41 is rotatably fitted to the main housing 20. The second connecting cover 41 extends to form a second engaging member 43 toward the edge of one side of the main housing 20, and a second receiving slot 23 is opened on one side of the main housing 20 away from the speaker assembly 30. The second receiving groove 23 is used for receiving the second engaging member 43. The second catching pieces 43 may catch the second receiving grooves 23 as the second coupling cover 41 rotates relative to the main housing 20.

It is understood that the number of the second clamping members 43 and the number of the second receiving grooves 23 may be one or more, which is not limited in the embodiments of the present application.

For example, the second locking members 43 are provided in plurality at intervals on the circumference of the side of the second connection cover 41 facing the main housing 20, and the second receiving grooves 23 are provided in plurality at intervals on the circumference of the side of the main housing 20 facing the second connection cover 41.

The expansion module 42 may be, but is not limited to, a bluetooth module, an open play module, etc.

In this embodiment, the second clip 43 may include a second extending portion 431 and a second limiting portion 432. The second extending portion 431 extends to a side of the second connecting cover 41 facing the main housing 20, and the extending direction of the second extending portion 431 is a direction in which the second connecting cover 41 is opposite to the main housing 20. The second position-limiting portion 432 is protruded at one side of the second extending portion 431, and the second position-limiting portion 432 and the second connecting cover 41 are spaced apart from each other. The second receiving groove 23 may include a second slide groove 231 and a second relief groove 232. The second sliding slot 231 and the second yielding slot 232 are all through slots. The second receding groove 232 communicates with the second sliding groove 231. In a direction in which the second connection cover 41 and the main housing 20 relatively rotate, an extension length of the second slide groove 231 is greater than an extension length of the second relief groove 232.

It is understood that the second receding groove 232 may be opened on the sidewall of the second sliding groove 231. In the diameter direction of main case 20, the distance of second slide groove 231 from the edge of main case 20 is greater or smaller than the distance of second relief groove 232 from the edge of main case 20.

In this embodiment, the second sliding slot 231 is used for accommodating the second extending portion 431, and the second extending portion 431 is slidably connected with the second sliding slot 231 along the rotation direction of the second connecting cover 41. The second avoiding groove 232 is used for the second limiting portion 432 to pass through, so that the second limiting portion 432 enters the hollow space of the main housing 20. Along with the sliding of the second extending portion 431 in the second sliding slot 231, the second stopper portion 432 moves in the main housing 20 away from the space of the second sliding slot 231 and moves from the position corresponding to the second avoiding slot 232 to the position dislocated from the second avoiding slot 232.

It can be understood that after the second engaging member 43 enters the second receiving slot 23 along the direction in which the second connecting cover 41 and the main housing body 20 are opposite, that is, after the second extending portion 431 enters the second avoiding slot 232, along with the relative rotation of the second connecting cover 41 and the main housing body 20, the second extending portion 431 slides in the second sliding slot 231, the second limiting portion 432 is dislocated from the second avoiding slot 232, and the portion of the inner wall of the main housing body 20 close to the second receiving slot 23 limits the movement of the second limiting portion 432 in the direction in which the main housing body 20 faces the second connecting cover 41, so that the second extending portion 431 is continuously located in the second sliding slot 231, and in the process of the relative rotation of the second connecting cover 41 and the main housing body 20, the second engaging member 43 is prevented from being disengaged from the second receiving slot 23.

In some embodiments, the inner wall of the main housing 30 facing the second connection cover 41 is provided with a second protrusion 24. The second protrusion 24 is disposed corresponding to the second sliding groove 231. The second projection 24 has elasticity.

It can be understood that, when the second extending portion 431 enters the second avoiding groove 232, the second connecting cover 41 and the main housing 20 rotate relatively, so as to drive the second extending portion 431 to slide in the second sliding groove 231, and move the second extending portion 431 from the position aligned with the second avoiding groove 232 to the position away from the second avoiding groove 232. Along with the sliding of the second extending portion 431, the second protrusion 24 abuts against the second limiting portion 432, the second limiting portion 432 pushes the second protrusion 24 to generate elastic deformation, and then the second extending portion 431 continues to slide. When the second extending portion 431 slides to the second avoiding groove 232 and the second limiting portion 432 to avoid, that is, the second limiting portion 432 does not have a portion aligned with the second avoiding groove 232, the second limiting portion 432 is released from abutting against the second protrusion 24. The second protrusion 24 is restored by its own elastic force, and restricts the movement of the second stopper portion 432 from a side close to the second receding groove 232. The inner wall opposite to the side of the second protrusion 24 and away from the second receding groove 232 in the second sliding groove 231 and the second protrusion 24 cooperate to limit the sliding of the second clamping member 43, so as to limit the rotation of the second connecting cover 41, and to realize the fixed connection between the rear cover assembly 40 and the main casing body 20.

It is understood that the second protrusion 24 may be integrally formed with the main housing 20. The second protrusion 24 and the main housing 20 may be made of a material having elasticity, which may be, but is not limited to, plastic.

It can be understood that the limitation of the movement of the second clamping member 43 by the second protrusion 24 realizes the fixed connection of the second connection cover 41 and the main casing body 20, that is, the fixed connection of the rear cover assembly 40 and the main casing body 20. When it is necessary to replace the expansion module 42 to realize different additional functions, a user may rotate the second connection cover 41, so that the second protrusion 24 is elastically deformed by the second extension portion 431, and the second stopper portion 432 is moved to a position corresponding to the second avoiding groove 232, and then the user may detach the rear cover assembly 40 from the main housing 20. The user can re-mount the rear cover assembly 40, which satisfies the use requirement, on the main housing 20 by rotating. Namely, the user can replace the expansion module 42 by a simple action of rotating the second connection cover 41, which improves the convenience of operation.

In some embodiments, at least two second connection terminals 421 are disposed on the expansion module 42, at least two connection reeds (not shown) are disposed on a side of the circuit board module 50 facing the second connection cover 41, and the two second connection terminals 421 are respectively used for abutting against the two connection reeds, so as to connect the expansion module 42 and the circuit board module 50. The two second connection terminals 421 are provided in one-to-one correspondence with the two connection reeds.

It can be understood that when the second engaging member 43 enters the second receiving groove 23, that is, the second position-limiting part 432 enters the hollow space of the main housing 20 through the second receding groove 232, the second connecting terminal 421 and the connecting spring are spaced apart from each other. When the second engaging member 43 rotates to the second protrusion 24 to limit the reverse movement of the second engaging member 43, and the second engaging member 43 is fixed in the second sliding groove 231, the second connecting terminal 421 abuts against the corresponding connecting spring, so that the circuit board module 50 is electrically connected to the expansion module 42. The circuit board module 50 may supply power to the expansion modules 42 to enable operation of the pair of expansion modules 42.

The embodiment of the present application provides an implementation principle of the modular headset 100 including: when the speaker module 32 needs to be installed, the user first moves the speaker assembly 30 to the position where the first locking member 33 is aligned with the first receiving slot 21, and then drives the first connecting cover 31 to be close to the main housing 20. The first limiting portion 332 enters the first sliding slot 211 through the first avoiding slot 212. The user rotates the first connecting cover 31 to drive the first engaging member 33 to rotate synchronously, the first limiting portion 332 moves to intersect with the first receding groove 212, and the first extending portion 331 slides in the first sliding groove 211. Along with the sliding of the first extending portion 331, the first protrusion 333 abuts against the inner wall of the first sliding slot 211, and the inner wall of the first sliding slot 211 pushes the first protrusion 333 to generate elastic deformation. With further rotation of the first connection cover 31, the first position-limiting portion 332 moves to a position where the first protrusion 333 corresponds to the slot 213, and the first protrusion 333 is restored under the action of its own elastic force and is engaged with the slot 213. The first protrusion 333 engages with the engaging groove 213 to restrict the relative rotation between the first connection cover 31 and the main housing 20, so that the first connection cover 31 and the speaker module 32 are mounted. When the horn module 32 needs to be replaced, the user may rotate the first connecting cover 31 in the opposite direction, so that the first protrusion 333 is elastically deformed and moves out of the slot 213, and then the first connecting cover 31 and the horn module 32 are replaced synchronously.

When the expansion module 42 needs to be installed, the user first moves the rear cover assembly 40 to the position where the second locking member 43 is aligned with the second receiving groove 23, and then drives the second connecting cover 41 to be close to the main housing 20. The second stopper 432 enters the main housing 20 through the second avoiding groove 232. The user rotates the second connecting cover 41 to drive the second clamping member 43 to rotate synchronously, the second limiting portion 432 moves to be staggered with the second abdicating groove 232, and the second extending portion 431 slides in the second sliding groove 231. Along with the sliding of the second extending portion 431, the second protrusion 24 abuts against the second limiting portion 432, and the second limiting portion 432 pushes the second protrusion 24 to generate elastic deformation. With the further rotation of the second connection cover 41, the second limiting portion 432 moves to be away from the second avoiding groove 232, and the second protrusion 24 is restored under the action of its own elastic force. The second protrusion 24 restricts the reverse rotation of the second connection cover 41 and the main housing body 20, the inner wall of the second sliding groove 231, which is opposite to the side of the second protrusion 24 and is away from the second avoiding groove 232, restricts the further rotation of the second connection cover 41, and the second protrusion 24 abuts against the side of the second limiting portion 432, restricts the reverse rotation of the second connection cover 41 and the main housing body 20, thereby realizing the installation of the second connection cover 41 and the rear cover assembly 40. When the expansion module 42 needs to be replaced, the user can rotate the second connection cover 41 reversely again, so that the second protrusion 24 is elastically deformed to release the blocking of the second extension portion 431, and then the second connection cover 41 and the expansion module 42 are replaced synchronously.

With the modular earphone 100 provided by the embodiment of the present application, a user can mount and dismount the speaker module 32 and the expansion module 42 through a rotating action, thereby improving the convenience of the user in operation.

While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
