Abstract:

A speaker including a frame, and a magnet assembly coupled to the frame. The magnet assembly forms an air gap through which a magnetic flux is directed. The speaker further including a voice coil suspended in the air gap, a diaphragm coupled to the voice coil and a compliant suspension member for suspending the voice coil within the air gap. The suspension member includes an electrically conductive member for providing an electrical connection between the voice coil and a circuit coupled to the frame.
