ELECTROMAGNETIC EXCITER AND MANUFACTURING METHOD THEREFOR

摘要

A thin electromagnetic exciter has a flat casing including a casing body (2) and a cover (3), a stator (10) including an electromagnet having a coil wound around a yoke, and an oscillator (20) including a bar-shaped permanent magnet and a weight integrally attached thereto. The stator and the oscillator are disposed adjacently over a bottom wall portion (2c) of the casing body. The stator is secured to the casing body. The oscillator is vibratably supported relative to the casing body through resilient support members.
