Description

Technical Field

[0001] The utility model relates to the technical field of sound level meter mounting brackets, in particular to a sound level meter mounting bracket for noise detection. Background Art

[0002] A sound level meter is the most basic noise measurement instrument. It's an electronic device, but unlike objective electronic instruments like voltmeters, it converts acoustic signals into electrical signals, simulating the time characteristics of the human ear's response to sound waves. It has varying sensitivity characteristics and intensity characteristics that change with loudness. A sound level meter is a subjective electronic instrument.

[0003] After searching, in the prior art, application number CN202023108749.8 discloses a sound level meter. When the upper rotating plate and the lower rotating plate are in the unfolded state, the sound level meter body can be placed on the ground or table at an angle through the support limit assembly. At this time, people can read the sound size of the ring to be tested through the display on the sound level meter body without holding the sound level meter body; when the upper rotating plate and the lower rotating plate are in the tightened state, the upper rotating plate and the lower rotating plate are both located in the shelf slot, so that people can conveniently place the application in a drawer or a sound level meter storage box, and people can place the sound level meter body in a noisy environment and obtain the readings of the application in the noisy environment in real time through a handheld device (such as a mobile phone). In this way, the application can avoid people being affected by the noisy environment, making the use of the application more convenient and intelligent.

[0004] However, the device and the prior art still have the following defects:

[0005] The sound level meter is not convenient to install on the wall or the ground, and it is not convenient to adjust the angle of the sound level meter after fixed installation, which makes it inconvenient to detect noise at different positions and angles. In addition, there is no good positioning effect between the frame and the sound level meter, which makes it inconvenient to conduct sufficient noise detection as a whole, reducing the overall practicality. Utility Model Content

[0006] The utility model aims to provide a sound level meter mounting bracket for noise detection.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:
