PURPOSE:To enhance converting efficiency by moving a mover with radiation pressure from a sound field formed with a medium, along with sound wave to be generated with the working of oscillators. CONSTITUTION:When oscillators 2 are worked and sound wave is generated, then by its sound wave through liquid 6, a sound field is formed in a housing 1. The blades 5a of a rotor 5 on the progress of the sound wave bear radiation pressure from the sound field along with the progress of the sound wave. Besides, the sound wave transmitted through or shifted positionally from the blades 5a is reflected by the side walls 1a of the housing 1, and is confronted with the blades 5a different from said blades, and the blades bear radiation pressure from the sound field along with the progress of the reflected sound wave. As a result, the rotor 5 is rotated counter-clockwise by the force of the radiation pressure. The material of the housing 1 and the liquid 6 are set to have effective acoustic impedance, and then, a force due to the radiation pressure can be efficiently obtained. Then, converting efficiency can be enhanced. |
