ABSTRACT:
A sound transducer converts electrical signals into mechanical motion. A transducer comprises a transducer housing including a diaphragm section having an inner concave surface and an outer convex surface. A stem element projects outwardly from the diaphragm housing section and has a structural configuration effective to penetrate a panel or sounding board. A securing device is adapted to cooperate with the stem for connecting the diaphragm housing section to the sounding board. An electromagnetic driver assembly is resiliently mounted to the inner surface of the diaphragm housing section. The electromagnetic driver assembly includes an annular magnetic gap and a voice coil assembly located in the magnetic gap. The voice coil assembly includes a coil member having a cylindrical voice coil portion at one end thereof disposed in the magnetic gap and the other end thereof connected to the stem. Several embodiments show various forms of the housing, electromagnetic driver assembly and various couplnig, wiring and anti-resonant mechanisms for attaching the housing to a panel sounding board.
