发明名称 LINEAR VIBRATOR
摘要 PURPOSE: A linear vibration device is provided to prevent touch noise generated by shock applied on a stator with excessive vibration of a vibrator. CONSTITUTION: A linear vibration device(100) comprises a stator(110), a vibrator(120), and a lubricating unit(150). The stator comprises a coil(111) and a housing(113). The current is applied on the coil so the coil induces a magnetic field. The coil is fixed to the housing. The housing divides an internal space. The vibrator comprises a magnet(121) and a mass body(123). The magnet facing the coil is installed on one side of the vibrator. The mass body is coupled with the outside of the magnet. The lubricating unit is placed between the housing and the mass body. The lubricating unit slides the mass body along the housing.
