Energy converter

An energy converter, comprising

• a resonator adapted to operate at a range of frequencies at which the resonator generates a sound wave progressing like a beam in a medium;
• a movable member disposed in a progressive direction of said sound wave generated by said resonator, and adapted for being driven by an acoustic radiation pressure resulting from the progression of said sound wave, the movable member including an inclining surface which is inclined 45 degrees with respect to said progressive direction of said sound wave;
• and
• a reflector adapted for further reflecting said sound wave reflected from the inclining surface of said movable member.

An energy converter, comprising:

• a resonator adapted to operate at a range of frequencies at which the resonator generates a sound wave progressing like a beam in a medium;
• a rotor disposed in a progressive direction of said sound wave generated by said resonator, and adapted for being driven by an acoustic radiation pressure resulting from the progression of said sound wave, the rotor including a blade made of a sound wave reflectible material and disposed in said progressive direction of said sound wave;
• and
• a stator to which said resonator is fixed, the stator including a side wall disposed in said progressive direction of said sound wave generated by said resonator, the side wall being adapted for reflecting said sound wave in a direction facilitating a rotation of said rotor.

An energy converter, comprising:

• a stator;
• a resonator held to said stator, and adapted to operate at a range of frequencies at which the resonator generates a sound wave progressing like a beam;
• a medium disposed in said stator, and adapted for generating a sound field with said sound wave generated by said resonator;
• and
• a movable member disposed in a progressive direction of said sound wave generated by said resonator in said stator, and adapted for being driven in opposite directions by an acoustic radiation pressure resulting from the progression of said sound wave in said sound field generated by said medium.

An energy converter, comprising:

• a stator;
• a resonator held to said stator, and adapted to operate at a range of frequencies at which the resonator generates a sound wave progressing like a beam;
• a medium disposed in said stator, and adapted for generating a sound field with said sound wave generated by said resonator;
• and
• a rotor disposed in a progressive direction of said sound wave generated by said resonator in said stator, and adapted for being driven by an acoustic radiation pressure resulting from the progression of said sound wave in said sound field generated by said medium, the rotor including a plurality of blades made of a sound wave reflectible material.

An energy converter, comprising:

• a stator;
• a pair of resonators held at least to said stator, disposed in a predetermined angular relationship, and adapted to operate at a range of frequencies at which the resonators generate a sound wave progressing like a beam in a medium;
• and
• a movable member held movably relative to said stator and including at least a pair of surfaces, the surfaces being disposed in a progressive direction of said sound wave and being adapted for receiving an acoustic radiation pressure resulting from the progression of said sound wave, said movable member being adapted to be driven in opposite directions when the surfaces receive acoustic radiation pressure.
