A high clearness sound absorbing screen is provided to perform absorption and extinguishment of sound energy on a single screen, thereby being used as a background screen of a concert, an auditorium, and a stage back ground screen. A high clearness sound absorbing screen includes an imaging side, a frame(3), fixing pins(4), and a vibration plate(5). A front surface of the screen is an elastic permeating side formed by a thin film with permeability and elasticity, and a rear surface is an imaging side formed by a thin film with a diffusing function to form an image of a projector. The fixing pins are arranged at the inner side of the frame at regular intervals. |
