Patent ID: 8461969

Claim:
A dual mode vibrator, comprising: a housing; a coil secured at an interior of the housing; a first vibrating unit formed in the vicinity of the coil to initiate vibrations in response to a current of a first frequency band applied to the coil; a second vibrating unit formed in the vicinity of the coil and arranged opposite to the first vibrating unit to vibrate in association with the coil if a current of a second frequency band is applied to the coil; a first elastic member secured at the housing to support one side of the first vibrating unit; a second elastic member secured at the housing to support one side of the second vibrating unit; and deformation prevention means provided at the housing between the other side of the first vibrating unit and the one side of the first and second vibrating units to prevent the first and second elastic members from being plastic-deformed; wherein each one side of the first and the second vibrating units is provided with a first support hole and a second support hole, and the deformation prevention means is inserted into the first and the second support holes to be secured at the housing, wherein the first and second vibrating units vibrate and rotate about a first support bar and a second support bar each at a predetermined angle, wherein the deformation prevention means is a stopper coupled to the housing to restrain the other portion of either the first vibrating unit or the second vibrating unit from moving at a predetermined distance or more, and wherein the stopper is formed with a cushioning material.
