Claim Text:
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 third direction; an exciter that is attached to the vibrating body and is configured to bend and vibrate the vibrating body in the first direction that is a thickness direction of the exciter by vibrating the exciter itself; an enclosure that is joined to the vibrating body, the enclosure and the vibrating body forming a first space; and a duct that is provided at the enclosure and is configured to connect between the first space and external space, wherein in the first space, a spacing between the vibrating body and a surface of the enclosure facing the vibrating body in the first direction is smaller than ½ of a length of a wavelength of resonance having the lowest frequency in bending vibration of the vibrating body, and in the third direction, a center of the vibrating body is positioned farther than a center of the first space from a connecting portion between the first space and the duct.
