ABSTRACT:
A microphone apparatus consists of a microphone body which incorporates a built-in microphone chip; a microphone cover formed of a net material and secured to the front end of the microphone body to enclose and protect the microphone chip inside; and a resilient ring whose outer circumference is shaped into a polygon. The resilient ring may be fitted directly over the net microphone cover; or it may be installed in a coupling ring that connects separated base and end portions of the microphone cover together. The polygonal outer surface of the resilient ring on the microphone cover prevents the microphone apparatus from rolling and fall when placed on a table because one of the flat sides of the polygon which is in contact with the table surface stabilizes the apparatus. Thanks to its resiliency, the polygonal resilient ring can be removed from the microphone cover so that any change that might occur when the ring blocks the sound wave can be prevented.
