PORTABLE ELECTRONIC APPARATUS WITH MICROPHONES

摘要

Two microphone assemblies (3) each having a main sound hole (61M) and an auxiliary sound hole (61S) are arranged facing the same direction at positions spaced apart from each other, the main sound hole (61M) being shifted to one side relative to the axis of an electret capacitor microphone (4) and communicating with the rear surface (4B) of the electret capacitor microphone (4), the auxiliary sound hole (61S) being shifted to the side opposite the one side of the axis of the electret capacitor microphone (4) and communicating with the front surface (4F) of the electret capacitor microphone (4). The main sound holes (61M) are provided in a surface (1F) of a housing (10) and the auxiliary sound holes (61S) are provided in other surfaces (1R, 1L) continuous to the surface (1F) of the housing (10), and directional axes determined by the positions of the auxiliary sound holes (61S) and the positions of the main holes (61M) are set to an angle where the axes spread from each other.
