Description

Rotary dimming sound-absorbing board wall

Technical Field

The utility model belongs to the field of wall decoration, relates to a sound insulation wall for rooms such as classrooms and the like, and particularly relates to a rotary dimming sound absorption board wall.

Background

The teaching task of the school is usually performed in a classroom, and as the information technology develops, the more and more school teachers borrow the multimedia technology in teaching. In the multimedia teaching process, courseware such as videos, PPT, pictures and the like need to be played by using playing equipment, and sound on a platform is amplified by using sound amplifying equipment such as a loudspeaker, a sound box and the like. The use help of public address equipment gives lessons mr with not little sound just can guarantee that the student in the classroom can listen to the content of lecture clearly, but public address equipment also can lead to sound to propagate outside the classroom simultaneously, influences the campus environment, therefore multimedia classroom can set up the diffusion that facilities such as sound insulation curtain reduced sound usually. The playing equipment usually has certain requirements on light in a classroom, a platform cannot be too bright and direct light which directly irradiates the platform to project on a screen cannot be generated, otherwise the screen can be projected to reflect light, images are blurred, students under the platform need to contrast textbooks and record notes, and then sufficient illumination is needed, and the two have contradictions. At present, the conventional multimedia classroom usually adopts the sound insulation curtain as the wall of the multimedia classroom, when going to school, after pulling up the sound insulation curtain, although the sound insulation effect has been played, but also block light simultaneously, need to throw light on in the room and throw light on, the energy is wasted, and the sound insulation curtain of this form has not too big difference with lightproof sound-absorbing walls such as cinema in use, the outdoor light has been completely obstructed, can't carry out natural lighting, especially to the students of the sensitive fine arts institute of colour, the colour of article has certain difference under natural light and under light, the influence to the effect of giving lessons is especially obvious.

Disclosure of Invention

The utility model aims to solve the problems that the existing sound insulation curtain blocks natural lighting from the outdoor and needs to be turned on for light supplement while sound insulation is achieved, and provides a rotary dimming sound absorption board wall which can block sound and enable natural light to illuminate indoors in a non-direct mode, sound insulation is achieved, and natural lighting is achieved.

The utility model adopts a technical scheme for solving the technical problems that: the utility model provides a rotation is adjusted luminance and is inhaled flitch wall, sets up the inboard of taking the window outer wall in the room, including a plurality of vertical abatvoix that set up side by side, abatvoix top and the coaxial pivot that is provided with in bottom, the top or the bottom of abatvoix are equipped with drive pivot pivoted rotating electrical machines, the abatvoix has the support sheet layer and adheres to the sound absorbing layer on the support sheet layer. The sound absorption plate wall of the device is arranged on the inner side of the outer wall of a room with windows, and the sound absorption plates are vertically arranged and are rotatably arranged one by one. When each abatvoix rotates to the coplanar, can play the effect similar with the sound insulation curtain, cut off light when blocking sound, this kind of mode is used when night, and outdoor no natural light plays the optimal effect that gives sound insulation. When outdoor natural light was sufficient daytime, the abatvoix rotated 30 ~ 45 degrees on the basis of coplanar, and the abatvoix is the tilt state that is parallel to each other this moment, can play indoor outer syllable-dividing effect equally, and the clearance of abatvoix can let the natural light jet into, has the daylighting of natural light concurrently, can the energy saving to introduce the natural light, avoid the colour difference under the light illumination.
