Abstract
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.
