ABSTRACT:
A vibration actuator harmoniously generates both longitudinal and bending vibrations to thereby induce motion in a relative moving member. The vibration actuator improves drive efficiency and reduces soldering defects by providing an improved mounting between an electrical energy delivery member and electrodes. The elastic member is connected to an electro-mechanical converting element to convert electrical energy into mechanical displacement. The electrodes are disposed on the electro-mechanical converting element in a location approximately at a node of vibration on the elastic member. A plurality of electrically conductive sections are disposed between the plurality of thermal energy non-conducting sections and about the electrodes. The thermal energy non-conducting sections reduce damage to the electro-mechanical converting elements during the soldering process while the electrically conductive sections electrically connect each electrode to a respective electro-mechanical converting element.
