Abstract

An acoustic reflector includes a reflection portion on which an elliptical reflection surface is formed, in which sound output from a speaker device that has an output position of the sound at or near one focal point on the elliptical reflection surface is reflected by the elliptical reflection surface, and the reflection portion has a size that reflects sound in a range of equal to or less than a nominal directional angle of the speaker device. As a result, because an outer shape of the reflection portion is formed to have a size in the range corresponding to the nominal directional angle of the speaker device, it is possible to reduce the size of the acoustic reflector.
