Abstract
An electroacoustic transducer employing a polymer connection for maximizing volume displacement. The transducer includes a diaphragm in a case and means for converting. The diaphragm includes a central portion. The means for converting converts between an electric signal and a vibration of the central portion of the diaphragm or vice versa while the diaphragm is coupled to the case. The central diaphragm has an outer edge, and between the outer edge and the inner wall of the transducer case a capillary space is present in which a polymer is provided as a coupling between the outer edge and the inner wall of the case.
Claims4
A method for manufacturing a transducer, comprising the steps of:
- providing a case having an inner wall portion;
- forming a diaphragm assembly, said diaphragm assembly including a central diaphragm portion having a circumferential edge;
- disposing into said case said diaphragm assembly such that said circumferential edge of said central diaphragm assembly and said inner wall portion of said case have a capillary space therebetween;
- and
- providing a polymer in said capillary space to connect said diaphragm assembly to said inner wall portion.
