Abstract
Official abstract text for this publication.
Provided are a sound generator and an electronic apparatus using the same. The sound generator includes a vibrating body, an exciter that is attached to the vibrating body and bends to vibrate the vibrating body in the thickness direction of the vibrating body by vibrating the exciter itself, an enclosure that is joined to the vibrating body and forms a first space enclosed together with the vibrating body, and a duct that connects between the first space and the external space. A spacing between the vibrating body and the surface of the enclosure facing the vibrating body is smaller than ½ of the length of the wavelength of resonance having the lowest frequency in the bending vibration of the vibrating body.
First claim
Opening claim text (preview).
The invention claimed is: 1. A sound generator, comprising: a vibrating body that has a first direction, a second direction, and a third direction, wherein the first direction, second direction, and third direction are orthogonal to one another, wherein the vibrating body has a shape in which a dimension in the second direction is larger than a dimension in the third direction, and a dimension in the first direction of a thickness direction is smaller than the dimension in the thi…
