Microphone-mounted earphone
Disclosed is a microphone-mounted earphone including a housing, a speaker unit accommodated in the housing, and a microphone. Here, the housing includes a sound emission path formed in front of the speaker unit to emit a sound generated by the speaker unit toward the outside. The housing includes a microphone installation groove recessed from an outer surface of a front of the speaker unit toward the sound emission path. The microphone is installed in the microphone installation groove. Also, the microphone-mounted earphone further includes a cover configured to cover the microphone installation groove not to allow the microphone to be exposed outward.
1. A microphone-mounted earphone comprising:
a housing;
a speaker unit accommodated in the housing;
a microphone; and
a substrate on which the microphone is mounted,
wherein the housing comprises a sound emission path formed in front of the speaker unit to emit a sound generated by the speaker unit toward the outside,
wherein the housing comprises a microphone installation groove recessed from an outer surface of a front of the speaker unit toward the sound emission path,
wherein the microphone is installed in the microphone installation groove,
wherein the substrate is mounted on a bottom surface of the microphone installation groove, and
the microphone-mounted earphone further comprising a cover configured to cover the microphone installation groove not to allow the microphone to be exposed outward.
2. The microphone-mounted earphone of claim 1 , wherein a microphone hole of the microphone is disposed toward the substrate,
wherein a first opening is formed in the substrate at a position corresponding to the microphone hole, and
wherein a second opening is formed in the bottom surface to allow the sound emission path and the first opening to communicate with each other.
3. The microphone-mounted earphone of claim 2 , wherein the first opening and the second opening are disposed at positions which disaccord with each other, and
wherein a communication groove is formed in the bottom surface from the second opening to a position corresponding to the first opening to allow the second opening and the first opening to communicate with each other.
4. The microphone-mounted earphone of claim 3 , wherein the communication groove is formed to have an L shape.
5. The microphone-mounted earphone of claim 2 , wherein a third opening is formed in the bottom surface to allow the sound emission path and an internal space of the microphone installation groove to communicate with each other, and
wherein a conduit is formed in the housing to allow the internal space of the microphone installation groove and a space in the rear of the speaker unit in the housing to communicate with each other.
6. The microphone-mounted earphone of claim 5 , wherein the conduit is formed along an outside of the speaker unit from an inner surface, which faces a front of the earphone, among inner surfaces of the microphone installation groove.
7. The microphone-mounted earphone of claim 2 , wherein a third opening is formed in the bottom surface to allow the sound emission path and an internal space of the microphone installation groove to communicate with each other, and
wherein a fourth opening is formed in the cover to allow the internal space of the microphone installation groove to communicate with the outside.
8. The microphone-mounted earphone of claim 7 , further comprising a mesh member configured to cover the fourth opening.
