Abstract
Provided is a multi-functional type vibration actuator capable of stabilizing behavior of a magnetic circuit unit by preventing stress from concentrating on a connecting portion in a frame-shaped suspension. In the frame-shaped suspension, a plurality of support portions are formed to configure the connecting portion, and a strength of the connecting portion is improved by a suspension fixing portion and the support portions, thereby stabilizing the behavior of the magnetic circuit unit.
Claims2
A multi-functional type vibration actuator comprising:
- a sound reproduction unit which includes a diaphragm in which a voice coil is provided;
- and
- a magnetic circuit unit which includes a yoke on which a magnet is provided, the magnetic circuit unit being supported by a frame-shaped suspension in a housing on which the sound reproduction unit is fixed,
- wherein each of connecting portions between the frame-shaped suspension and the housing is formed by a plurality of supports.
