ABSTRACT:
The present invention relates to a capacitor microphone which is characterized that even in a microphone with a small diameter such as a lavalier microphone, the noneffective electrostatic capacitance enables to be decreased and a better signal-to-noise ratio enables to be obtained.As shown in FIG.2,in the capacitor microphone in which a vibration plate10strained and fixed on a support ring11and a charge back-plate20supported on one end-side of a cylinder base21face each other and are disposed through a spacer forming a gap, the spacer30A having at least three spacer pieces, in which the each spacer piece has the same thickness and is disposed apart from the adjacent spacer pieces at generally equal angle on the same circumference, in place of the ring-shaped spacer.
