When converting sound signals into electrical signals, it can simulate the time characteristics of the human ear's response speed to sound waves; the frequency characteristics with different sensitivities to high and low frequencies, and the intensity characteristics that change the frequency characteristics at different loudness levels. A sound level meter is a subjective electronic instrument. During a meeting in a conference room, there are many people. Video recording is required during the meeting. During video shooting, it is necessary to quickly find the speaker in a timely manner, so an automatic positioning console is needed to locate the sound source.

Support rods with their lower ends rotatably connected to the receiving grooves are vertically arranged in the receiving grooves. The outer sides of the lower ends of the support rods are fixedly connected with positioning plates that are inclined upward from the lower ends of the support rods and tend to the outer side of the support rods. Each support rod can rotate outward until the positioning plate abuts against the outer side of the lower end of the receiving frame. The lower end of the receiving frame is also threadedly connected with a fixing sleeve whose upper end can be sleeved on each positioning plate. The utility model has the advantages of being able to reduce the error of the test results caused by the tester holding the sound level meter by hand, being convenient to use, and ensuring the test results.
