Abstract
A piezoelectric panel speaker improved in frequency characteristics has a panel and a piezoelectric exciter for vibrating the panel. The exciter includes a casing and a piezoelectric exciter element accommodated in the casing. The casing has an outer surface with a part positioned proximate to and facing one side surface of the panel. The side surface of the panel has an area opposed to the part of the outer surface of the exciter. A securing layer is partially formed between the area of the panel and the part of the outer surface to secure the exciter to the panel. The securing layer is made of a material so that vibration is transmittable from the exciter to the panel.
Claims9
A piezoelectric panel speaker comprising:
- a panel having opposite side surfaces;
- a piezoelectric exciter for vibrating said panel, said exciter including a casing and a piezoelectric exciter element accommodated in said casing, said casing having an outer surface with a part positioned proximate to and facing one of said opposite side surfaces, said part having a securing portion and a rest portion;
- said one of said side surfaces having an area opposed to said part of said outer surface, said area having a securing portion and a rest portion;
- and,
- a securing layer formed between said securing portions of said area and said part of said outer surface and adapted to secure said exciter to said panel, said securing layer being made of a material so that vibration is transmittable from said exciter to said panel.
