... SPEAKERS The speaker converts an electrical signal into sound. A cross section of a typical Knowles speaker is shown in Fig. 3. The basic components of the speaker are: a coil of wire, a metal U-shaped reed called the armature, a pair of permanent magnets, a drive rod, and a diaphragm. The coil and armature act as an electromagnet. An alternating current in the coil causes the polarity of the armature to switch back and forth from north to south ...
