Abstract
A microphone is provided in which two circuit boards are held in spaced parallel position by each being connected at one end to a supporting member and by each resting at the other end in a pair of stabilizing grooves located within the microphone head. A battery holding assembly has attached at one end the supporting member, and at the other end an antenna mounting surface onto which a coiled antenna is placed. A battery holding compartment is located between the supporting member and the antenna so that a battery held in the compartment acts as an addition to the antenna itself. A power and battery level indicator flashes on and off to warn that the charge of the battery is reaching a predetermined low point. The electronic circuitry for the indicator is also provided.

A hand held, battery powered microphone comprising:
- (a) an internal assembly comprising:
- (i) a frame having a front surface and a rear surface, said frame comprising:
- (a) a supporting member extending longitudinally from said front surface of said frame;
- (b) an antenna mounting surface adjacent said rear surface;
- and
- (c) a battery holding compartment located between said supporting member and said antenna mounting surface for receiving therein a battery;
- (ii) a pair of spaced parallel circuit boards having requisite microphone circuitry thereon and each having a front end and a back end with said boards being secured to said supporting member about said respective back ends;
- and
- (b) a microphone head having means for stabilizing said circuit board front ends in spaced parallel relationship to each other;
- and
- (c) a housing of a length to receive therein said internal assembly and including means to detachably secure said microphone head to said housing.
A frame for holding internal components of a battery powered microphone having a pair of parallel circuit boards and a coiled antenna, comprising:
- (a) a tubular body portion having a front surface and an opposed rear surface;
- (b) an antenna mounting surface on said body portion adjacent said rear surface on said frame for holding said coiled antenna;
- (c) a supporting member extending longitudinally from said front surface capable of having said pair of parallel circuit boards mounted thereon;
- (d) a battery holding compartment on said body portion between said supporting member and said antenna mounting surface for receiving therein a battery;
- and
- (e) a circular flange located on said front face of said frame for holding said frame stable within a housing.
