Abstract:
A multifunction oscillatory actuator which performs acoustic reproduction by an acoustic reproduction section includes a diaphragm having a voice coil attached thereto and performs the occurrence of somesthetic oscillation by a magnetic circuit section having a magnet attached thereto, and in which the acoustic reproduction section and the magnetic circuit section are attached to a housing having a cylindrical shape, such that the magnetic circuit section is supported on an inner wall of the housing by a frame-shaped suspension.
