Sliding cable type acoustic plate and sliding cable type acoustic plate wall

The invention relates to a sliding cable type acoustic plate and a sliding cable type acoustic plate wall, and belongs to the field of building materials. The sliding cable type acoustic plate comprises a sound absorbing plate, a pulley track and a connecting device; the sound absorbing plate comprises a first sound absorbing plate body and a second sound absorbing plate body which are symmetrically arranged; the connecting device comprises a first connecting device body and a second connecting device body, and the first connecting device body and the second connecting device body are fixedlyconnected with the upper ends and the lower ends of the first sound absorbing plate body and the second sound absorbing plate body correspondingly; and the pulley track comprises a first pulley trackbody and a second pulley track body, the first pulley track body is arranged on the surface of the first connecting device body, and the second pulley track body is arranged on the surface of the second connecting device body. The sliding cable type acoustic plates are spliced to form the sliding cable type acoustic plate wall, and the joints of splicing of the sliding cable type acoustic plates are subjected to vacuum adsorption. The sound isolating quality of the sliding cable type acoustic plate wall is high, and the situations that the sound insolating effect is weakened and an overall structure of a wall plate is loosened after long-time using are avoided.
