Abstract
An electro acoustic transducer has a housing having an axial threaded bore. A transducer driver element is axially aligned in the bore and has a first end mounted on an electrically conductive holder that is axially displaceable by a conductive screw member. A hemisphere on the other end of the driver element contacts a diaphragm for radiating acoustic signals. An electrical connector has a conductive coil spring coupled to the screw member and is electrically connected to the first end of the driver element via the coil spring, screw member, holder, and mounting plug. Another electrical connector is connected to the other end of the driver element via a conductive front plate, diaphragm, and hemisphere in one embodiment or a flexible lead in another embodiment. In both embodiments, the electrical connectors couple electrical driving signals to the driver elements to cause the driver elements to mechanically vibrate.
