ABSTRACT:
A transducer comprises a diaphragm including a perimeter, a motor for causing the diaphragm to vibrate in response to an electrical signal corresponding to program material to convert the electrical signal to motion of the diaphragm and thus to an audio reproduction of the electrical program material signal, and a surround and a frame for supporting the diaphragm from its perimeter to permit such motion. Additional diaphragm supports are provided on the frame and project from the frame toward the diaphragm. Additional compliances are provided on the diaphragm and are coupled to the additional diaphragm supports. The additional compliances are located adjacent the additional diaphragm supports.
