Abstract
An electro-dynamic loudspeaker is typically provided with a diaphragm mounted to a frame in tension. The diaphragm is provided with a plurality of electrical traces that are disposed within a magnetic field of a plurality of magnets that are mounted to the frame. Electric current applied to the circuit causes electric current to pass through the wiring that interacts with the magnetic field of the magnets to thereby cause vibration of the diaphragm that causes the sound generated by the electro-dynamic loudspeaker. Electrical connector arrangements and methods are provided for connecting the electric circuit of the diaphragm to a power amplifier.
