Problems solved by technology
[0004] However, since the quiet room is adjacent to the production line, the flow sound of parts on the production line during operation and the vibration of parts during operation will cause noise interference to the quiet room, thereby reducing the staff's ability to identify small abnormal sounds , and the eligibility of a gear system depends in large part on the presence of such small, unusual sounds
In addition, when the gear system is in operation, the sound it emits varies from time to time, and the decibel meter shows rapid fluctuations. It is difficult for the staff to clearly know the maximum and minimum values of the sound, which will affect the judgment of the production quality of the gear system.

This application discloses a sound collection system, which is used to collect the sound emitted by the gear system during operation. It includes a box body and a sound collector arranged in the box body. connected and the sound collector is used for setting relative to the gear system, and the sound collector is connected with the sound box device. With such a setting, the sound from the gear system can be transmitted in a relatively closed environment by using the box, which can prevent the noise in the external environment from interfering with the sound from the gear system and improve the sensitivity to the sound from the gear system when it is running. Recognition ability, and use the speaker equipment to play the sound, which is convenient for the staff to analyze the sound, and then can improve the accuracy of the detection of the gear system.
Description
technical field [0001] The invention relates to the technical field of automobile production, in particular to a sound collection system. Background technique [0002] With the development of the automobile industry, users have higher and higher requirements for the driving environment. During the driving process, the rear axle gear system will emit a sound with a small decibel value but obviously different from normal operation, but this sound will be serious. affect the user's driving experience. Therefore, in the production process of the rear axle gear, it is necessary to detect the sound of the rear axle gear when it is running. [0003] The existing noise detection of the gear system is to set up a silent room, the silent room is equipped with an installation platform, install the gear system to be tested on the installation platform, drive the gear system to rotate, and the staff use the decibel meter or directly use the ear to identify The size of the sound, and th...
