PROBLEM TO BE SOLVED: To provide a thin multi-functional vibrating actuator capable of adjusting the diameter of the diaphragm determined by the housing inner diameter to improve acoustic characteristics according to the backward capacity of the diaphragm, when the backward capacity of the diaphragm is decreased by making the multi-functional vibrating actuator thinner. SOLUTION: The acoustic characteristics can be optimized by a grill, using a structure of attaching the diaphragm to a housing through the grill. In addition, since a sound emitting hole can be prepared in the direction of the lower surface of the housing, the effect of thinner making can be also attained. COPYRIGHT: (C)2010,JPO&INPIT
