Audio mirror speaker |
摘要 |
In an audio mirror speaker, an uneven area is formed on a planar mirror surface and a directivity distribution is controlled by changing a relative position of a diaphragm facing the mirror surface and the mirror. The directivity distribution of such a speaker is determined by a radius of curvature of the uneven area. Since the directivity changes with various movements of the planar mirror, a freedom in setting the directivity distribution is enhanced.
