Abstract

The utility model discloses an entotic earphone, which comprises a horn, a shell and a diaphragm; the diaphragm is compressed between the horn and the shell, so the size of the diaphragm is not limited by the size of a metal shell of the horn and can be the same as the size of the metal shell of the horn. Therefore, the size of the diaphragm can be larger than the size of the diaphragm of the current earphone; once the size of the diaphragm is larger, the timber effect of a low-frequency part is better.

Description

A kind of In-Ear Headphones

Technical field

The utility model relates to a kind of earphone, particularly a kind of In-Ear earphone.

Technical background

For earphone, the size dimension of diaphragm has crucial influence to the acoustical quality of low frequency part, and the acoustical quality of big more its low frequency part of diaphragm is also just good more.In-Ear Headphones is filled in during use in auricle, is subjected to the restriction of auricle, and its size has certain limitation, and the size of diaphragm also has certain limitation, can not do very greatly.Existing In-Ear Headphones as Fig. 1, is made of loudspeaker 1a, shell 2a and diaphragm 3a, diaphragm 3a is pasted on the inboard of loudspeaker metal-back, because the loudspeaker metal-back has thickness, is subjected to the restriction of loudspeaker metal-back, the inevitable size of the size of its diaphragm 3a less than the loudspeaker metal-back.

The utility model content

The purpose of this utility model is to provide that a kind of diaphragm can do more, the In-Ear Headphones of low frequency tonequality better effects if.

In-Ear Headphones of the present utility model comprises loudspeaker, shell and diaphragm, it is characterized in that: diaphragm is pressed between loudspeaker and the shell.

In-Ear Headphones of the present utility model, its diaphragm is pressed between loudspeaker and the shell, rather than be pasted on the inboard of loudspeaker metal-back, the big I of diaphragm and loudspeaker metal-back measure-alike, thereby the more existing In-Ear Headphones of the size of diaphragm can be bigger, and the acoustical quality of bigger its low frequency part of diaphragm is also just better.

Description of drawings

Fig. 1 is the generalized section of existing In-Ear Headphones;

Fig. 2 is the generalized section of In-Ear Headphones of the present utility model.

Embodiment

Embodiment 1, and as Fig. 1, In-Ear Headphones comprises loudspeaker 1, shell 2 and diaphragm 3, and diaphragm 3 is pressed between loudspeaker 1 and the shell 2.

Diaphragm 3 is pressed between loudspeaker 1 and the shell 2, the size of its diaphragm 3 is not subjected to the restriction of loudspeaker metal-back, and what size can be with the loudspeaker metal-back is measure-alike, thereby diaphragm 3 can do more than existing product, diaphragm 3 is bigger, and the acoustical quality of earphone low frequency part is also just better.

Because diaphragm 3 is thinner, damage easily during installation, need extremely careful.Impaired in installation process for preventing diaphragm 3, make installation more convenient, can be pasted on the becket 4 around the diaphragm 3, can only operate becket 4 during installation, thereby not fragile diaphragm 3, easier for installation.

Claims

1. an In-Ear Headphones comprises loudspeaker (1), shell (2) and diaphragm (3), it is characterized in that: diaphragm (3) is pressed between loudspeaker (1) and the shell (2).

2. In-Ear Headphones according to claim 1 is characterized in that: between loudspeaker (1) and the shell (2) becket (4) is arranged, diaphragm (3) is pasted on the becket (4).
