Drawer type adjustable sound absorbing system capable of realizing automatic control and control method of system

Abstract

The invention discloses a drawer type adjustable sound absorbing system capable of realizing automatic control and a control method of the system. The system comprises a casing, sliding rails, a drawer component, connecting pieces, a driving component and a control switch; a cavity is formed in the casing; each sliding rail comprises an outer rail and an inner rail glidingly connected with the outer rail, and the outer rail extends into the cavity from the open end of the cavity; the drawer component comprises a drawer and an inner sound absorbing container, the drawer comprises an accommodating groove and is fixedly connected with the inner rails, and the inner sound absorbing container is fixed in the accommodating groove and is exposed out of or accommodated in the casing; the casing isfixed to a roof by the aid of the connecting pieces; the drawer is driven by the driving component to slide; and the control switch controls starting and stopping of the driving component. Accordingto the scheme, the system can be suspended on the roof, so that the acoustic absorption problem in the vertical direction in a room can be solved effectively; meanwhile, the sound absorption amount can be adjusted through adjustment of the pulling degree of the inner sound absorbing container; and automatic telescoping of the drawer can be realized, and the exposing area of the inner sound absorbing container is convenient to control, so that graded accurate adjustment and control on the sound absorption amount can be realized.

Description

technical field [0001] The invention relates to the technical field of indoor acoustic experiments, in particular to an automatically controlled drawer-type adjustable sound-absorbing system and a control method thereof. Background technique [0002] The indoor sound absorption system can effectively reduce the reverberation time in the room, and has been widely used in various indoor scenes, such as large concert halls and theaters. And, along with the continuous improvement of the indoor sound-absorbing system, its sound-absorbing effect is also continuously improved, such as a kind of sound-absorbing body component disclosed by CN205012488U patent. [0003] The sound-absorbing body component includes a sound-absorbing body and a connector structure. The sound-absorbing body is arranged indoors through the connector structure. The skeleton of the sound-absorbing body is fixed on the bearing keel, and the bearing keel is fixed on the roof or wall through the keel hanger. B...
