The sound reproducing screen by an ultrasonic wave converting and reproducing method is disclosed. According to the invention it is possible to reproduce the audio signal by a plurality of cells through a screen of a continuous grid structure separating the audio signal that is sent carried on ultrasonic waves from the ultrasonic wave. Therefore, whereby the cell structure of the screen is disclosed in accordance with. With this structure, it is possible to the structure of a converter of the sound signal by ultrasonic conversion playback simply, it is possible to maximize the conversion efficiency. Furthermore, as well as a high frequency range it has excellent sound reproducing efficiency of the low-frequency region, and can implement a three-dimensional sound systems, such as practical.
