Abstract:
A microphone (130) is fitted with a mounting portion (130a) of a front case (12) in a state being set to a microphone folder (134). A metallic mesh-wise sheet (132) is attached to a front face of the microphone. When an EL sheet (110) on a rear face of the front case emits light by supplying power to it, electrical noise is radiated from the EL sheet. The mesh-wise sheet of the front face of the microphone blocks the electrical noise from the EL sheet, which may enter through a sound hole (131) to the inside of the microphone.
