Abstract

Disclosed is an ear microphone which includes: a microphone for converting a voice signal provided from the external auditory meatus of a user to an electric signal; a speaker for converting the electric signal provided from an external device to the voice signal; and a soundproof member having a microphone receiving groove for fixing and supporting the microphone to the inside of the housing and a speaker receiving groove for fixing and supporting the speaker to the inside of the housing.

Claims

1. An ear microphone comprising:

a microphone converting a voice signal provided from an external auditory meatus of a user into an electric signal;

a speaker converting an electric signal provided from an external apparatus into a voice signal; and

a soundproof member including a microphone-receiving groove for fixing and supporting the microphone within a housing, and a speaker-receiving groove for fixing and supporting the speaker within the housing,

wherein an input terminal of the microphone and an output terminal of the speaker are disposed in a surface facing the external auditory meatus,

the microphone is a capacitor microphone including a back hole, and

the soundproof member includes;

a first penetrating groove providing an output signal of the speaker to the external auditory meatus;

a second penetrating groove providing the voice signal provided from the external auditory meatus to the input terminal of the microphone; and

at least one of third penetrating grooves providing the voice signal provided from the external auditory meatus to the back hole of the microphone, wherein the at least one of third penetrating grooves is disposed in the surface facing the external auditory meatus.

2. The ear microphone of claim 1, wherein the housing includes a housing-separating film separating the output signal of the speaker from an input signal of the microphone.

3. The ear microphone of claim 1, further comprising:

a cover,

wherein the cover includes a cover-separating film separating the output signal of the speaker from an input signal of the microphone.
