Description

technical field [0001] The invention relates to the field of car audio, in particular to a fast fixing structure for a car audio PCB board. Background technique [0002] Car audio is a sound recording and playback device set up to relieve the boring feeling of the driver and passengers during travel. The earliest use was the car AM radio, and later the AM FM radio, tape player, and developed to the CD player and compatible with DCC and DAT digital audio. Nowadays, car audio has reached a high standard in terms of timbre, operation and anti-vibration. It can cope with the bumps of the car on rough roads, ensuring stable performance and perfect sound quality. [0003] Automobile is a vehicle that can be driven by its own power, and can be driven by motor without the need for rails or electric power. In a broad sense, a vehicle with four wheels is generally called a car. [0004] Printed circuit boards, also known as printed circuit boards, are providers of electrical connec...
