Document Type and Number:
Japanese Patent JP2000509649
Kind Code:
A
Abstract:
In a preferred embodiment, a flexural plate sound transducer (150), including: a housing (152) having an open central volume (172); a flexural plate (154) attached around an inner surface of the housing (152) and extending across the central volume (172); at least one piezoelectric element (162, 164) attached to a surface of the flexural plate (154); and a mechanical hinge (194) formed in the flexural plate (154) and extending around the flexural plate (154) near an outer periphery thereof, the mechanical hinge (194) being formed such as to cause the flexural plate (154) to move in a substantially piston-like manner when the piezoelectric element (162, 164) is energized.
