Abstract
A device for regenerating powerful acoustic pressure comprises at least an arrangement for generating sound while utilizing the flextensional technique, i.e. having at least one surface element (2), the opposite ends (4, 5) of which are arranged to be influenced to oscillate away from and towards each other, and the surface element oscillating transversely thereto and generating sound.
Claims25
A device for generating powerful acoustic pressure in air comprising at least an arrangement for generating sound while utilizing a flextensional technique, having at least one surface element or membrane (2) opposite ends (4,5) of which are arranged to be influenced to oscillate away from and towards each other and by the surface element oscillating transversely thereto and generating sound,
- said surface element being light but nevertheless stiff by having a high stiffness with respect to the average density thereof, said membrane being coupled to an air transformer and/or pressure chamber for generating powerful acoustic pressure.
