Microphone having improved transducer support

Claim 1

In a microphone having a diaphragm and transducer connected to be driven thereby, the combination comprising: a hollow housing having a top, bottom and of substantially constant lateral cross section; elongated transducer means; conductive means of like lateral cross section insulatedly mounted in proximity to the bottom of said housing; an insulating washer of like lateral cross section mounted in proximity to the bottom of said housing on top of said conductive means, said washer having an inwardly, upwardly, opening notch disposed over said conductive means and adjacent to a side wall of said housing whereby the bottom of one end of said transducer means may be disposed in said opening in conductive supporting engagement on said conductive means; and a conductive spring washer having a first portion fixedly mounted intermediate the top and bottom of said housing and having an outside lateral dimension greater than the lateral interior of said housing for more than one-half of the outer peripheral dimension of said housing, and a second portion having an outside lateral dimension less than the lateral interior dimension of said housing, but greater than that of the interior lateral dimension of said insulating washer, for less than one-half of the peripheral dimension of said housing, said last named portion extending downwardly toward the top of said insulating washer and said transducer means and in registration with the notch in said insulating washer, whereby the top of said end of said transducer is conductively engaged by the second portion of said conductive spring washer.
