Abstract
A light from a light source is output uniformly in the circumferential direction even if a shift or inclination occurs in a constituent member of a sound signal transmitter. A sound signal transmitter of a microphone includes a light source that outputs a light corresponding to a sound signal from a sound source, a division part that divides the light from the light source into a plurality of divided lights, and a reflector that reflects the divided lights from the division part.
