ABSTRACT:
In a close talking microphone device in use for a communication apparatus for a motorcycle, a front casing 2 and a back casing 3 are provided with a front opening 7 and a back opening respectively. Elastic supporting members 5, 6 and 15 for a microphone 4 are accommodated through a first and second filters 11 and 12 between the front casing 2 and the back casing 3 and formed thereon with first, second and third through holes 13, 14 and 16 connected to each other. The microphone 4 is engaged within the third through hole to form a pair of sound paths at each front and back side of the microphone 4. The front sound path is smaller in volume than the back sound path and the opening size of the through hole 13 is defined narrower than that of the through hole 14, whereby a sideward noise diverges into two courses "a" and "b" and the diverging noises reaching the microphone are cancelled by each other so as to be dampened.
