ABSTRACT:
The periphery of the diaphragm of a loudspeaker is mechanically connected to a diaphragm support or basket by a layer of acoustic dampening-adhesive material. The layer of acoustic dampening-adhesive material covers a sufficient portion of the surfaces of the diaphragm to dampen standing waves which would otherwise reflect from the periphery of the diaphragm. Thus, a unitary diaphragm mechanical termination-acoustic termination structure is formed.
