PURPOSE: To surely mount a speaker and a bone conduction microphone to an ear by integrating the speaker and the bone conduction microphone to an ear-mount member, and mounting the ear-mount member to a recessed part between the ear and a bead with stressing force.
CONSTITUTION: A speaker support 10 mounted with a speaker 3, a microphone support 11 mounted with a bone conduction microphone 4 and an ear-mount 12 touched to the rear side of the ear constitute an ear latch member 1. When the ear latch member 1 is mounted to the ear, the speaker 3 is touched to the ear. On the other hand, the microphone support 11 and the ear latch part 12 are mounted to the rear side of the ear 2 while being compressed. Then the microphone support 11 presses the microphone 4 into contact with a chin under the ear. Moreover, the ear latch part 12 is abutted on the rear side of the ear 2 to clip the ear 2 with a proper force.
