Abstract

The invention discloses an automobile noise detection device, and the device comprises a noise collection module, a signal conversion module and a control module. The input end of the signal conversion module is connected with the output end of the noise collection module, and the output end of the signal conversion module is connected with the input end of the control module. The device also comprises a fixed support which can be installed between front seats of an automobile. The fixed support is used for fixing the noise collection module, and the noise collection module comprises a plurality of microphones which are used for collecting noises of the automobile in all directions. The device can effectively detect the noise of the automobile in each direction, and enables a user to judge whether each part of the automobile has a fault or not more easily. In addition, the invention also discloses an automobile noise detection system.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile noise detection device and an automobile noise detection system. Background technique [0002] In recent years, with the improvement of people's living standards, cars have gradually become an indispensable means of transportation in people's daily life. When a car is running, it will produce various dynamic noises, including engine noise, road noise, tire noise and wind noise. However, when a car breaks down, there will be abnormal noise, which is quite different from the noise under normal conditions. The propagating position of this noise is mainly judged by the experience of the maintenance personnel, but the general driver does not have such ability. Therefore, the driver can install a car noise detection device inside the car to detect the noise of various parts of the car. [0003] In the prior art, the vehicle noise detection device can only detect th...
