PROBLEM TO BE SOLVED: To provide a multi-functional vibration actuator which is not subject to limitations on the arrangement place in an attachment housing mounting the actuator, easily achieves the overall thickness reduction, and easily maintains the vibration characteristics. SOLUTION: The adoption of a structure, in which a weight formed as a separated body is partially cut out, prevents the reduction of the air viscosity and the horizontal displacement of a magnetic circuit part, improves the durability, and also improves the overall reliability. Further, the structure allows the entire actuator to be easily formed into a thin structure and thus achieves space saving effect in an attachment housing. COPYRIGHT: (C)2013,JPO&INPIT |
