Abstract
An electro-acoustic transducer has a planar annular diaphragm suspended at both the inner and outer periphery. The transducer component is situated within the inner periphery and interacts with the diaphragm via outwardly extending connections.
Claims2
An electro-acoustic transducer means comprising:
- diaphragm means, said diaphragm means having an outer periphery and an internal aperture bounded by an inner periphery,
- rigid chassis means, said chassis means having a first portion extending around said diaphragm means outer periphery and a second portion disposed within said diaphragm means internal aperture and around which said diaphragm means inner periphery extends,
- first diaphragm suspension means, said first diaphragm suspension means extending between said diaphragm means outer periphery and said first portion of said chassis means,
- second diaphragm suspension means, said second diaphragm suspension means extending inwardly from said diaphragm means inner periphery to said second portion of said chassis means,
- electro-mechanical transducer means acting between said diaphragm means and said chassis means,
- means mounting said electro-mechanical transducer means within said chassis means second portion, and
- connecting means extending outwardly from said electromechanical transducer means to drivingly engage said diaphragm means.
