Abstract

The invention discloses a vehicle-mounted audio playback system, comprising a media connection module, a network identification module, a signal receiving module, a storage module, a signal processingmodule, an FM transmitting module and a vehicle-mounted connection module, wherein the media connection module, the network identification module, the signal receiving module, the signal processing module, the FM transmitting module and the vehicle-mounted connection module are sequentially connected, the media connection module is connected with a media server and is used to transmit an audio signal on the media server to the signal receiving module, and the network identification module is used to identify the network condition when the vehicle-mounted audio playback system is started. Thevehicle-mounted audio playback system disclosed by the invention has high audio transmission efficiency and quality, does not have audio transmission distortions, and is low in noise and high in soundquality; and moreover, a Bluetooth interface of the media server does not need to be occupied during the audio transmission, and the energy and traffic of the media server also do not need to be consumed during operation.

Description

technical field [0001] The invention relates to the technical field of vehicle audio playback, in particular to a vehicle audio playback system. Background technique [0002] Car audio (auto audio) is a sound recording and playback device set up to relieve the boring feeling of drivers 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] With the development of science and technology, the existing car audio has more functions. It can connect to the smart phone through the Internet and Bluetooth, and play the audio files in the phone. The file is decoded and then transmitted to the car MP3 via Bluetooth, so at least the following ...
