Title:
LINEAR VIBRATOR
Document Type and Number:
WIPO Patent Application WO/2011/043536
Kind Code:
A1
Abstract:
The present invention relates to a linear vibrator in which a permanent magnet, a coil unit, and a circuit board are arranged in a case, and a mass vibrates by means of the electromagnetic force acting between the coil unit and the permanent magnet when power is applied to the circuit board from an external source. The linear vibrator of the present invention comprises a vibration-absorbing member interposed between the mass and the case in order to prevent the mass and the case from contacting each other and to reduce vibrations in the directions other than the movement direction of the mass by means of the elastic force thereof, thereby reducing noise caused by contact with the case during the vibration of the mass.
