PURPOSE:To efficiently reduce the vibration of an electric apparatus, by causing a first inertial mass body to support a second inertial mass body through a second spring to efficiently cause a high vibrating force. CONSTITUTION:A leaf spring 8 is mounted on a first inertial mass body comprising a permanent magnet 4 and yokes 5A, 5B, so that the first inertial mass body supports an auxiliary inertial mass body 9. The natural frequencies f1, f2 of the first and the auxiliary inertial mass bodies are set at an integer ratio to the high frequency of electric power so that a high vibrating force is efficiently caused. According to this constitution, the vibration of an electric apparatus is efficiently reduced by a compact vibrator. |
