ELECTRONIC APPARATUS AND MOUNTING STRUCTURE OF MICROPHONE IN SAME

PROBLEM TO BE SOLVED: To achieve a dust-proof property, a water-proof property, the reduction of wind noise, enhancement of wind pressure resistance, prevention of sticking with sharp-edged things, and improvement of tone quality at a low cost. SOLUTION: A microphone 25 mounted on a circuit board is joined to an inside surface of a front case 9 in a close contact state through a frame-like double-sided adhesive sheet stuck to a peripheral edge of a ceiling face so that a microphone sound hole 25a is kept a prescribed distance apart from a case sound hole 9a for transmission, and a dust-proof mesh sheet subjected to water-repellent treatment is stuck to an inside edge part of the case sound hole 9a for transmission through a frame-like double-sided adhesive sheet, and a stratified space constituting a sound path is formed by the double-sided adhesive sheets.
