| Zusammenfassung: | To provide a vibration actuator capable of reducing differences in vibration phases and vibration amplitudes at low voltage when driving a contact body using multiple vibrating bodies.SOLUTION: A vibrating actuator includes a vibrating body unit and a contact body that move relative to each other. The vibrating body unit includes multiple transformers in which a primary coil is connected in series and a vibrating body connected in parallel to each secondary coil of the transformers.SELECTED DRAWING: Figure 1
【課題】複複数の振動体を用いて接触体を駆動する際に低電圧で振動位相および振動振幅の差を小さくすることができる振動型アクチュエータおよび振動型アクチュエータの駆動装置を提供する。【解決手段】相互に相対移動する振動体ユニットと接触体とを備える振動型アクチュエータであって、振動体ユニットは、１次側コイルが直列接続される複数のトランスと、複数のトランスのそれぞれの２次側コイルに並列に接続される振動体と、を備える。【選択図】図１ |
