This icon is meant to represent a microphone. It uses a circle with a line through it to represent the business end of the microphone and a tapering rectangle of uneven sides to represent the handle. There is a small line running parallel to the sides of the handle that represents the power switch and curved line coming out of the bottom of the handle that represents the power cord.
