Abstract

The utility model discloses an insert-earphone, which comprises a shell body and a sounding unit arranged in the shell body, and is characterized in that a channel for communicating the inside and the outside of an auditory meatus is arranged on the insert-earphone. The channel for communicating the inside and the outside of the auditory meatus is arranged on the insert-earphone, so that the pressure in the auditory meatus can be eliminated, a user cannot feel uncomfortable when using the insert-earphone for a long time, and the injury on hearing can be reduced.

Description

Insert earphone

Technical field

The utility model relates to a kind of insert earphone.

Background technology

When existing insert earphone was placed in the ear, its end face and duct constituted sealing, can cause certain pressure to duct, can cause hearing to descend after long-time the use, and What is more understands other user and lose hearing.

Summary of the invention

The purpose of this utility model is: provide a kind of insert earphone that uses comfortable minimizing to hearing impairment at the prior art deficiency.

The technical solution of the utility model is:

A kind of insert earphone comprises the pronunciation unit that housing and housing are built-in, it is characterized in that: have to be communicated with the inner and extraneous passage of duct on insert earphone.

Optimal technical scheme of the present utility model is as follows:

Preferably, branch is fluted on the periphery of insert earphone and ear contact-making surface, and this groove constitutes the passage that is communicated with the duct inside and the external world.

Preferably, insert earphone is In-Ear structure, is having through hole on the insert earphone with on the flexible member that duct contacts, and this through hole forms and is communicated with the inner and extraneous passage of duct.

Preferably, insert earphone is In-Ear structure, on the insert earphone with flexible member that duct contacts on the cylinder of the fixing flexible member that contact with duct on have the through hole of symmetry, this through hole forms the passage that is communicated with the inner and external world of duct.

Preferably, insert earphone is In-Ear structure, has the groove of symmetry on the cylinder of the fixing flexible element on the insert earphone, and this groove forms and is communicated with the inner and extraneous passage of duct.

Preferably, insert earphone is In-Ear structure, and the inboard of the flexible member that contacts with duct on insert earphone has groove, and this groove forms and is communicated with the inner and extraneous passage of duct.

Preferably, insert earphone is In-Ear structure, has air vent hole on the housing of insert earphone, and this air vent hole forms and is communicated with the inner and extraneous passage of duct.

Preferably, insert earphone is In-Ear structure, and several petal-shaped structures are adopted in the outside of the flexible member that contacts with duct on insert earphone, and the gap between several petal-shaped structures forms and is communicated with the inner and extraneous passage of duct.

The beneficial effects of the utility model are: owing to have the inner and extraneous passage of connection duct on the insert earphone, can eliminate the pressure in the duct, can not cause when using insert earphone for a long time and user's discomfort reduce the damage to hearing.
