Abstract: A headset includes an enclosure holding a speaker and a microphone. The enclosure includes: a main body portion which holds the speaker and in which an earphone portion attached to an ear is provided; a microphone holding portion which holds the microphone; and a coupling portion which couples the main body portion to the microphone holding portion. When a side where the earphone portion is provided is a front surface side of the enclosure, in a side surface portion of the microphone holding portion, a sound hole communicating with the microphone is formed.

Abstract: An earphone microphone includes a single speaker, a microphone having first and second sound input holes, and a main body casing in which an acoustic space is formed. The acoustic space includes a sound output path in which output sound propagates, a first sound input path communicating with outside, in which sound to be input to the first sound input hole propagates, and a second sound input path in which sound to be input to the second sound input hole propagates. The sound output path branches into one path communicating with outside of the main body casing and the other path communicating with the second sound input path. Input sound from a sound source outside the main body casing is input while input of output sound is suppressed by acoustic resistance of the acoustic space.

Abstract: An acoustic space including a sound output path, first and second sound input paths is formed in a main body casing of an earphone microphone. Output sound from a speaker propagates in the sound output path. Sound input to a first microphone propagates in the first sound input path communicating with outside. Sound input to a second microphone propagates in the second sound input path. The sound output path branches into one path communicating with the outside of the main body casing and the other path communicating with the second sound input path. The earphone microphone amplifies a sound signal output from at least one of the first and second microphones so as to input sound from a sound source outside the main body casing, and suppresses input of the output sound.

Abstract: An earphone microphone includes a main body housing, a differential microphone, and a speaker. The main body housing defines first and second acoustic spaces therewithin. The main body housing has a first opening that communicates the first acoustic space with an outside of the main body housing and a second opening that communicates the second acoustic space with the outside of the main body housing. The second acoustic space forms a Helmholtz resonator relative to sound propagating through the second opening. The differential microphone has first and second sound collection holes. The first and second sound collection holes communicate with the first and second acoustic spaces, respectively. The speaker is disposed in the second acoustic space.
