Display device for two-dimensional distribution of sound field

The utility model discloses a display device for two-dimensional distribution of a sound field. The display device comprises a box body, a sounder arranged on the box body, and a sound sensing plate which is arranged on the box body and is used for displaying phase information of standing waves through photoelectricity, the box body is further provided with a sliding groove used for guiding the sounder to move and a baffle used for blocking the sliding groove. By moving the sounder, the position of the sound source can be changed, so that different standing waves can be generated at different positions, and the phase information of the standing waves at different positions can be displayed through the sound sensing plate and the light change; in addition, the box body is arranged, and the inner wall of the box body is used for reflecting sound waves, so that the use number of the sounders can be reduced; according to the scheme, on one hand, the device can reduce the number of used sounders, on the other hand
