SUSPENSION SUPPORT STRUCTURE OF MULTI-FUNCTIONAL TYPE VIBRATION ACTUATOR |
| 摘要 |
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. |
