To solve the above-described problems, as an aspect of the present utility model, there is provided an earphone including: preceding shell, well shell and loudspeaker, loudspeaker set up in the well shell, preceding shell with the one end of well shell is connected, keeping away from of preceding shell the sound hole has been seted up to the one end of well shell, the inside of preceding shell is formed with annular sound chamber, the sound pipe of well shell with annular sound chamber intercommunication, set up on the preceding shell with the sound hole of annular sound chamber intercommunication.

Preferably, a C-shaped connecting portion is provided protruding inside the front case, the sound outlet pipe is connected to the C-shaped connecting portion, and an opening of the C-shaped connecting portion communicates with the annular sound chamber.

Preferably, the sound outlet pipe and the C-shaped connecting part are bonded through glue.

Preferably, the sound outlet pipe is connected with the C-shaped connecting part through a sealing piece.

Preferably, the seal is made of EVA material.

Preferably, the middle shell further comprises a mounting shell matched with the front shell, the sound outlet pipe is inserted into the mounting shell, and a decorating part matched with the front shell is arranged in the mounting shell.

Preferably, a battery and a circuit board are further arranged in the middle shell, and the circuit board is connected with the loudspeaker and the battery.

Preferably, a rear case is provided at an end of the middle case remote from the front case.

In the technical scheme, the annular sound cavity is formed in the front shell of the earphone, so that sound emitted by the loudspeaker passes through the annular sound cavity and then is emitted from the sound Kong Chuanchu, the problem of low sound is solved, and meanwhile, the damage of the in-ear earphone to the hearing is improved.

Detailed Description

The following describes embodiments of the utility model in detail, but the utility model may be practiced in a variety of different ways, as defined and covered by the claims.

As one aspect of the present utility model, there is provided an earphone including: preceding shell 1, well shell 2 and loudspeaker 3, loudspeaker 3 set up in well shell 2, preceding shell 1 with the one end of well shell 2 is connected, preceding shell 1 keep away from well shell 2's one end has been seted up out sound hole 4, the inside of preceding shell 1 is formed with annular sound chamber 5, well shell 2 go out sound pipe 6 with annular sound chamber 5 intercommunication, preceding shell 1 go up seted up with the play sound hole 4 of annular sound chamber 5 intercommunication.

Preferably, a C-shaped connecting portion 7 is provided protruding inside the front case 1, the sound outlet pipe 6 is connected to the C-shaped connecting portion 7, and an opening of the C-shaped connecting portion 7 communicates with the annular sound chamber 5. Thus, after being transmitted from the sound outlet pipe 6, the sound enters the C-shaped connecting part 7, passes through the outlet of the C-shaped connecting part 7, enters the annular sound cavity 5, and is then transmitted outwards from the sound outlet hole 4.

Preferably, the sound outlet tube 6 and the C-shaped connecting part 7 are bonded by glue. In another preferred embodiment, the sound outlet tube 6 is preferably connected to the C-shaped connection 7 by means of a seal 8. Preferably, the seal 8 is made of EVA material. The glue and the seal 8 form a seal at the junction of the sound tube 6 and said C-shaped connection 7.

Preferably, the middle case 2 further includes a mounting case 13 matched with the front case 1, the sound outlet tube 6 is inserted into the mounting case 13, and the decorative member 9 matched with the front case 1 is disposed in the mounting case 13.

Preferably, a battery 10 and a circuit board 11 are further disposed in the middle shell 2, and the circuit board 11 is connected with the horn 3 and the battery 10. Preferably, the end of the middle case 2 remote from the front case 1 is provided with a rear case 12.

In the technical scheme, the annular sound cavity is formed in the front shell of the earphone, so that sound emitted by the loudspeaker passes through the annular sound cavity 5 and then is transmitted out of the sound outlet 4, the problem of low sound is solved, and meanwhile, the damage of the in-ear earphone to hearing is improved.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
