Abstract
An electromagnetic exciter that enables thickness reduction has a casing, a stator having an electromagnet and fixed in the casing, an oscillator having a permanent magnet, and an elastic support member that positions the oscillator in horizontally-opposed relation to the stator at a distance between them and that supports the oscillator oscillatably in a direction parallel to the stator. The elastic support member has a fixed portion fixed to the casing and a pair of arms extending from the fixed portion toward the stator along side surfaces of the oscillator to support the oscillator oscillatably. The oscillator is oscillated by an alternating magnetic field generated by application of an alternating voltage to the electromagnet of the stator.
