ABSTRACT:
A speaker includes a substantially rectangular case having connection terminals at corners, a substantially rectangular voice coil, a diaphragm, and a substantially rectangular magnetic circuit. A lead drawn out from a corner of the voice coil in proximity to one of the connection terminals extends to the vicinity of another corner on a shorter side of the voice coil. The lead is bent, and then is connected to the connection terminal. This configuration can provide a speaker for use in portable equipment, such as a portable telephone, that can meet the requirements of space reduction without impairing characteristics, such as sound quality and sound pressure, and has excellent connection reliability of the terminal and reduced cost.
