Abstract

PURPOSE: To make a switching-regulator-type power supply device compact, by using the field coil of a loudspeaker as a smoothing choke coil of the power supply device.
CONSTITUTION: A magnetic circuit including the field coil 15 of the loudspeaker 14 is formed. The field coil is used also as the smoothing choke coil of the switching- regulator-type power supply device. An aural output signal is supplied from a transformer to the voice coil 16 of the magnetic circuit. Since the field coil is used also as the choke coil 15, the power supply device is made compact.
