Why is there no sound from car music?

[RyanAnn]

Car music may have no sound due to reasons such as circuit failure or audio system damage. Circuit failure: Due to aging of the circuit and possible cutting or friction from plastic inside, the circuit may become disconnected or have poor contact, resulting in no sound from the audio system. Setting issues such as adjusting the audio to left and right channels can also cause the audio system to produce no sound. Introduction to car audio systems: Car audio systems consist of two main parts: the head unit and the speakers. The head unit, professionally defined as the sound source, converts digital signals from music software into corresponding electrical signals. It is installed on the car's control panel and serves as the core of any audio system, as well as an important component of the sound system. Speakers are electroacoustic transducers that convert electrical energy into sound energy. Their importance in the car audio system is extremely prominent, as their quality directly affects the system's playback performance. The function of speakers is to convert electrical energy into sound energy, thereby moving air to produce audio that enters the human ear, resulting in a good listening experience.
