MICROPHONE Russian patent published in 2014 - IPC H04R1/00 

FIELD: physics, acoustics.

SUBSTANCE: invention relates to acoustics, particularly microphones. A microphone comprises a hollow housing, a protective grid of a sound pickup, having a diaphragm, a moving coil, a magnetic element and a sound pickup switch. On the inner side of the protective grid there are hollow light-reflecting elements, each being fitted with at least one light-emitting diode capable of emitting white/colour light. The light-emitting diodes are connected by conductors to a unit for converting audio frequencies into optical radiation of the light-emitting diodes and a direct current source, mounted inside the housing. The light-reflecting element has the shape of a truncated cone/hyperboloid/pyramid adjoining the protective grid by the base. Part of the protective grid located opposite the light-reflecting elements has a light-reflecting coating. A light-emitting diode switch is mounted on the housing and an opening is made on the wall of the housing for inserting the plug of a charging device into the terminals of the direct current source. The tail part of the housing has a socket with pins. The invention enables to use a voice with accompanying differently coloured light flux. There is a light-splitting partition wall in the light-reflecting element between the light-emitting diodes.

EFFECT: broader functional capabilities by providing an illumination function.
