DEFINITION

Classification: 381/355

Housed microphone:

(under subclass 150) Subject matter having either a capsule supported within an enclosure, or a diaphragm and motor means supported relative to one another in order to convert sound waves into a varying electrical voltage, further including structure beyond that necessary to merely support the diaphragm and motor means relative to one another.

(1) Note. A microphone capsule is generally housed within a larger, unitary structure to provide protection, electrical connections, adequate size to be handled, acoustic properties, etc.
