Description

A wireless car audio system

technical field

The utility model relates to a wireless audio system, in particular to a wireless audio system. In particular, it relates to a wireless car audio system which is easy to install in a car and is convenient for a car owner to flexibly choose or replace with different grades and prices.

Background technique

Car audio systems are generally installed in passenger cars (passenger cars) to enrich the lives of drivers and passengers, activate the atmosphere in the car, relieve fatigue, and energize.

The traditional on-board car audio system consists of a large speaker located in the central control part of the car and multiple speakers connected to designated positions in the car through speaker cables. It is designed based on the principle of the lowest cost under the premise of ensuring that the inherent functions are fully reflected. For ordinary cars, the power of the audio system is small and the sound quality is poor, which is not suitable for many car owners and passengers to pursue new fashion needs. Therefore, many car owners want to modify the audio system of their car.

The traditional on-board car audio system is equipped as standard according to the price of the car body, and the audio and speakers of the same price are configured according to the price of the car body, and the wiring of the audio system is fixed. The car owner has no more flexible choices. And when making the car owner refit or upgrade the car audio system in the future, it will be more difficult and must pay a larger refit or upgrade fee.

The traditional modification method of the car audio system is to retain or replace the original car audio, add one or more car amplifiers, add multiple audio signal lines equal to the number of audio channels to connect the car audio and the car amplifier, and then use the same number of speakers Multiple sets of speaker wires to connect the power amplifier and speakers, and replace all the speakers. This method has at least the following disadvantages:

①. The traditional car audio system refitting method needs to lay out multiple audio signal lines and multiple sets of speaker lines, so the interior of the original car must be dismantled when refitting. The project is large, the project time is long, and the cost of engineering and materials is high. ; And the quality of the refitting staff directly affects the reliability and safety of the car's interior after disassembly.

②. Traditional car audio system modification needs to use a long audio signal line. The quality of the audio signal line and the reasonableness of the wiring will affect the size of the engine noise that is connected to the audio signal. If the noise is too loud, it will Seriously affect the listening effect.

③. The modification of the traditional car audio system also requires the use of long multiple sets of speaker wires. In order to ensure the sound quality, thicker speaker wires are required. Thicker speaker wires not only increase the cost, but also increase the weight of the car. If the rear speaker wire is much thicker than the original speaker wire, it may be necessary to change the structure of the car, which may affect the safety of the car.
