Method And Device For Controlling Wrinkles In A Vibratile Diaphragm

View page
US Patent:
42152496, Jul 29, 1980
Filed:
Apr 25, 1978
Appl. No.:
5/900016
Inventors:
John M. Reynard - Framingham MA
Thomas N. Carignan - Danvers MA
Richard Paglia - Carlisle MA
Joseph F. Rich - Danvers MA
Assignee:
Polaroid Corporation - Cambridge MA
International Classification:
H04R 714
H04R 1900
US Classification:
179111R
Abstract:
A method and device for significantly improving the efficiency and sensitivity of an electroacoustical transducer. A relatively inelastic vibratile diaphragm is preformed to the shape of a mating backplate prior to the time it is actually mated to said backplate. By such preforming, the efficiency and sensitivity reducing effects from a wrinkled transducer diaphragm are minimized in that said wrinkles move to a diaphragm region where they have no effect on transducer sensitivity when the backplate is subsequently mated to said diaphragm.
