[0002] A car amplifier is an audio power amplifier in a car audio and video system. Its function is to select and pre-process the audio input signal, amplify the power, and make the electrical signal have the ability to drive the speakers. Car amplifiers are slightly different from amplifiers in ordinary home theaters. Since many car hosts have integrated power amplification functions and serve as pre-amplification functions, car amplifiers are sometimes called post-amplification, which means that they can be connected to high-level inputs that have already been amplified.
[0003] However, it still has some disadvantages. For example, when the car amplifier is working, it will generate a lot of heat. The efficiency of the heat dissipation of the car amplifier depends on the size of the heat dissipation port. The larger the heat dissipation port, the higher and faster the heat dissipation efficiency. When encountering a high temperature environment, the heat dissipation port needs to be adjusted to enhance the heat dissipation effect. In addition, the heat dissipation ports of ordinary car amplifiers are all opened at the top of the car amplifier, and dust can easily fall inside the car amplifier, affecting the performance of the car amplifier.
[0004] In order to solve the above problems, the present application proposes a car amplifier device with noise reduction function. Utility Model Content
