For some users who have high requirements for the sound quality of car audio, the sound quality of car audio will directly affect their experience and use, and these tiny and messy abnormal noises will affect the sound of the audio. In the means of abnormal noise detection, the abnormal noise will be exposed in the spectrum. The spectrum is particularly effective for the detection of mechanical vibration or abnormal noise.

[0003] When detecting abnormal noise, it is necessary to use a sound collecting device to collect audio, and then use the software on the computer to detect the abnormal noise in the collected audio. When collecting audio information, it is necessary to place the microphone for collecting sound on the outside of the car audio to collect the audio. Since the car audio is mostly concentrated on the inside of the door, the microphone cannot be fixed on the door or near the audio when collecting audio. Secondly, the sound receiving part of the fixed microphone may be far away from the audio, or it cannot be set in a suitable position. There is a lack of structure for adjusting the position of the microphone. Finally, the microphone and the fixing device need to be able to be installed and disassembled. Therefore, in view of the above problems, an abnormal noise detection device for car audio is proposed. Utility Model Content

[0024] The diameter of the fixing groove 4 is larger than the diameter of the rubber ring 7; the diameter of the fixing rod 6 is smaller than the diameter of the circular hole 3, and the fixing rod 6 and the circular hole 3 are slidingly connected; the threaded hole 9 and the screw rod 11 are threadedly connected; there are three fixing plates 14, and the fixing plates 14 and the ball head 12 are rotatingly connected.

[0025] Working process: When the device is used, first determine the installation position, then adsorb the suction cup 5 on the surface of the installation position, and fix the suction cup 5 by pressing the fixing rod 6 at the top of the suction cup 5. When the handle 8 is pressed and the rubber ring 7 on the outside of the fixing rod 6 enters the fixing groove 4 on the inside of the circular hole 3, the suction cup 5 completely expels the air between it and the installation surface. At this time, the rubber ring 7 will remain inside the fixing groove 4. The fixing shell 2 is on the outside of the suction cup 5 to prevent the external influence on the suction cup 5, causing the suction cup 5 to fall off. There is a fixing frame 1 at the top of the fixing shell 2, and the straight rod 10 is connected through the screw 1 1 and the threaded hole 9 are connected, so that the straight rod 10 and the fixing frame 1 are connected.
