Detailed Implementation

[0021] This utility model embodiment provides a classroom sound and light environment coordinated adjustment device, such as... Figure 1-4As shown, the device includes a mounting base 101, which is installed on the ceiling of the classroom. Four vertical support rods 102 are fixed at the four corners of the bottom of the mounting base 101. The vertical support rods 102 are symmetrically arranged. A support frame 103 is installed and connected to the bottom of the vertical support rods 102. The support frame 103 has a mounting groove, and an indoor speaker 104 is installed inside the support frame 103. The inner wall of the mounting base 101 has mounting grooves 109 with opposite openings. A mounting rod 112 is fixed between the two walls of the mounting groove 109. Several arrayed curved hooks 110 are fixedly installed on the outer end face of the mounting rod 112. The curved hooks 110 are L-shaped.

[0022] It should be further explained that the number of mounting slots 109 corresponds one-to-one with the number of windows in the classroom, and the indoor speaker 104 can be connected to the teacher's microphone to transmit the teacher's teaching voice.

[0023] Furthermore, a rotating support disk 116 is fixedly provided at the bottom of the curved hook 110, and a rotating wheel 117 is rotatably provided inside the rotating support disk 116.

[0024] Furthermore, a drive shaft 119 is fixedly connected to the bottom of the rotating wheel 117, and the drive shaft 119 extends downward and passes through the bottom of the rotating support disk 116.

[0025] It should be further explained that the curved hook 110 is equipped with a rotating motor, which is poweredly connected to the rotating wheel 117. When the rotating motor is started, it can drive the rotating wheel 117 to rotate and change direction.

[0026] Furthermore, a curtain insert 108 is fixedly connected to the bottom of the drive shaft 119, and a sunshade curtain 107 is inserted into the bottom of the curtain insert 108.

[0027] It should be further explained that when the rotating motor starts, it drives the rotating support plate 116 to rotate and change direction, which in turn drives the curtain insert 108 to change its angle through the transmission shaft 119, which in turn drives the bottom sunshade curtain 107 to change its angle. When the sunshade curtains 107 on each side change their angle, the gap between the sunshade curtains 107 on both sides decreases. At this time, the brightness of the light source that can pass through is further reduced, and thus the brightness of the classroom is changed by changing the light transmittance of the sunshade curtain 107.

[0028] Furthermore, a control signal line 105 is fixedly connected to one side of the mounting base 101, and a controller 106 is connected to the bottom of the control signal line 105. The controller 106 is equipped with a control button 118.

[0029] It should be further explained that the control button 118 is used to manually control and adjust the angle of the sunshade curtain 107 and the volume of the indoor speaker 104. The controller 106 is equipped with a control panel, which can be programmed according to the built-in code to control and adjust the volume of the indoor speaker 104 and the rotation angle of the curtain insert 108 in the classroom, thereby realizing the adjustment of the sound and light environment in the classroom.

[0030] Furthermore, a signal transmission line 114 is connected to one side of the mounting base 101, and an environmental monitor 115 is installed and connected to the front end of the signal transmission line 114.

[0031] It is worth further explaining that the environmental monitor 115 is installed in the outdoor environment of the classroom and has an environmental monitoring module. This module integrates an ambient brightness sensor and an ambient noise sensor, which is responsible for accurately measuring the intensity of natural light outside the classroom. It uses a high-sensitivity photoelectric element to capture changes in light in real time and convert the light signal into an electrical signal for digital processing. At the same time, the sensor uses acoustic technology to accurately distinguish between background noise and sudden noise, effectively capturing the decibel value of ambient noise and its changing trend. These monitoring data are input into the classroom through the environmental monitor 115.

[0032] The following are the methods of using this utility model:

[0033] S1. First, correctly install the mounting base 101 on the classroom ceiling and match the number of windows in the classroom. Then, perform initialization settings through the control panel in the controller 106, including setting the basic parameters of the classroom, as well as the preset light intensity threshold and noise decibel threshold for sound and light environment adjustment.

[0034] S2. When the device is in automatic adjustment mode, the environmental monitoring module in the environmental monitor 115 will continuously monitor the ambient brightness and noise level outside the classroom. Once the ambient brightness is detected to exceed the preset threshold, the device will automatically start the rotating motor in the rotating support plate 116.

[0035] S3. When the rotating motor starts, it drives the rotating support plate 116 to rotate and change direction, which in turn drives the curtain insert 108 to change angle through the transmission shaft 119, which in turn drives the bottom sunshade curtain 107 to change angle. When the sunshade curtains 107 on each side change angle, the gap between the sunshade curtains 107 on both sides decreases or increases. At this time, the brightness of the light source that can pass through is further reduced, and thus the brightness of the classroom is changed by changing the light transmittance of the sunshade curtain 107.

[0036] When the environmental monitoring module in S4 and environmental monitor 115 detects that the noise level exceeds the preset value, it can automatically adjust the volume of the indoor speaker 104 through signal transmission and the control panel in controller 106 to ensure that the sound clarity in the classroom is not disturbed by the outside world, thereby realizing the coordinated adjustment of sound and light environment.

[0037] S5. If temporary adjustments are needed, the user can manually operate the control button 118 through the control panel inside the controller 106. Through the interface on the control panel, the user can intuitively see the current ambient brightness and noise level, and manually adjust the angle of the sunshade curtain 107 and the volume of the indoor sound system 104 to achieve a satisfactory effect.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
