HORIZONTAL LINEAR VIBRATOR

摘要

PURPOSE: A horizontal vibrator is provided to reduce a thickness of a PDA by vibrating to a longitudinal direction of the PDA. CONSTITUTION: A horizontal vibrator includes a cover portion(140), a bracket(110), a vibrator(120), a magnetic field portion(130) and sub mass portion. An internal space is formed between the cover portion and the bracket. The vibrator is arranged in the internal space to linearly move to the horizontal direction. The vibrator includes a mass. An insertion portion is formed on a single-side of the mass. The magnetic field portion supplies electromechanical power to the vibrator. The sub mass portion is inserted into the insertion portion to control a resonant frequency of the vibrator.
