Abstract
A loudspeaker in which a permanent magnet and associated yoke are encapsulated in a plastic housing. The voice coil and diaphragm are cemented to the top piece of the yoke to fix the position of the voice coil within the air gap defined by the yoke. The housing includes a quick bayonet type locking mechanism for locking the housing to a mounting plate, a circumferential groove which provides a receptacle for the loudspeaker grill, and a conduit through which conductors can pass to provide an electrical signal to the voice coil. The electrical signals are conducted through the housing by spring contacts which are biased against the conductive portion of a printed circuit board associated with the mounting plate to provide for a quick, sure electrical connection simultaneously with the mechanical connection.
