Sound absorption device capable of locally and automatically adjusting sound absorption angle
The invention belongs to the technical field of sound monitoring and absorption, and provides a sound absorption device capable of locally and automatically adjusting a sound absorption angle. The problem that the sound absorption angle of an existing sound absorption plate cannot be automatically adjusted according to the volume of sound is solved. The sound absorption device comprises a sound absorption plate and a controller, the sound absorption plate is arranged on a concrete plate, a rotating gap is reserved between the sound absorption plate and the concrete plate, a noise sensor is arranged on the sound absorption plate, a shaft frame and a motor are fixed to the concrete plate, the noise sensor and the motor are both connected with the controller, the sound absorption plate comprises a movable plate and a fixed plate, a swing arm is fixed to the movable plate and rotationally connected to the shaft frame through a rotating shaft, a torsional spring is arranged on the rotating shaft, and a folding and unfolding device for controlling the swing arm to rotate is arranged between the motor and the swing arm. By arranging the noise sensor, the decibel value of sound is detected, the detection result is transmitted to the controller, the controller controls the motor to rotate forwards and backwards, the swing arm is pulled to drive the sound absorption plate to rotate, and the function of automatically adjusting the sound absorption effect is achieved.
本发明属于声音监测和吸收技术领域，解决了现有吸音板不能根据声音大小自动调整吸音角度的问题。提供了一种可局部自动调整吸音角度的吸音装置，包括吸音板和控制器，吸音板设置在混凝土板上且与之留有转动间隙，吸音板上设置有噪音传感器，混凝土板上固定有轴架和电机，噪音传感器和电机均与控制器连接，吸音板包括活动板和固定板，活动板上固定有摆臂，摆臂通过转轴转动连接在轴架上，转轴上设置有扭簧，电机和摆臂之间设置有控制摆臂转动的收放装置。本发明通过设置噪音传感器，对声音的分贝值进行检测，并将检测结果传至控制器，通过控制器控制电机正反转，拉动摆臂带动吸音板转动，实现自动调整吸音效果的功能。
