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 first earphone unit including a microphone converting a first voice signal provided from a first external auditory meatus into an electric signal, a first speaker converting an electric signal provided from an external apparatus into a second voice signal and providing the converted second voice signal to the first external auditory meatus, and a first soundproof member having a microphone-receiving groove for fixing and supporting the microphone within a first housing and a first speaker-receiving groove for fixing and supporting the first speaker within the first housing;

a second earphone unit including a second soundproof member, the second soundproof member having a second speaker converting the electric signal provided from the external apparatus into a third voice signal and providing the converted third voice signal to a second external auditory meatus, and a second speaker-receiving groove for fixing and supporting the second speaker within a second housing; and

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

the microphone includes a back hole, and

the first soundproof member includes one or more penetrating grooves for providing the voice signal provided from the first external auditory meatus to the back hole of the microphone, and all of the penetrating grooves are disposed in a surface facing the first external auditory meatus.

2. The ear microphone of claim 1, wherein the first soundproof member includes a front end soundproof member and a back end soundproof member.

3. The ear microphone of claim 1, wherein any one of the first and second speakers outputs a high-note sound and the other of the first and second speakers outputs a low-note sound.

4. The ear microphone of claim 1, wherein the first speaker is a balanced-armature driver, and the second speaker is a dynamic driver.

5. The ear microphone of claim 1, wherein the first soundproof member includes:

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

a second penetrating groove for providing the voice signal provided from the first external auditory meatus to the input terminal of the microphone.

6. The ear microphone of claim 1, wherein the first soundproof member includes protrusions.

7. The ear microphone of claim 1, wherein the first earphone unit further includes the first housing, and the first housing includes a housing-separating film separating signals output from the first speaker from signals input to the microphone.

8. The ear microphone of claim 7, wherein the first earphone unit further includes a cover, and the cover includes a cover-separating film separating signals output from the first speaker from signals input to the microphone.

9. The ear microphone of claim 1, wherein the first speaker and the microphone are disposed in parallel to each other.

10. The ear microphone of claim 1, wherein an output terminal of the first speaker and an input terminal of the microphone are disposed toward the surface facing the first external auditory meatus.

11. The ear microphone of claim 10, wherein the one or more penetrating grooves comprise a first, second and a third penetrating grooves, and voice signal output from the output terminal of the first speaker is delivered to the first external auditory meatus via the first penetrating groove.
