Abstract

The invention discloses a same-frequency FM vehicle-mounted audio playback system, which includes an intelligent mobile terminal, a vehicle-mounted terminal and a vehicle-mounted power amplifier subsystem; the output end of the intelligent mobile terminal is connected to the input end of the vehicle-mounted terminal, and the vehicle-mounted The output terminal of the vehicle is connected with the input terminal of the vehicle power amplifier subsystem; the intelligent mobile terminal is connected with the vehicle terminal through wireless communication. It can real-time adjust the FM transmission frequency and the frequency transmitted by the smart terminal to achieve the same frequency, transmit the music of the smart terminal to the car terminal through Bluetooth and play it through the car audio, so as to achieve the music playback effect in the smart terminal; and can pass the display and Volume adjustment displays and adjusts the content and volume of the music played; it greatly improves the experience and satisfaction of passengers in the car.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted FM signal processing, in particular to a same-frequency FM vehicle-mounted audio playback system. Background technique [0002] With the continuous improvement of living standards, cars have become an indispensable means of transportation for people. Playing music during driving can not only relieve the driver's tension and improve driving safety, but also bring a pleasant feeling to other passengers in the car. The environment inside the car increases the satisfaction of passengers in the car. [0003] However, the existing vehicle-mounted equipment cannot automatically tune and match the frequency of the FM transmitter so as to realize the real-time synchronous transmission of music from the smart terminal to the vehicle-mounted stereo for in-vehicle playback, but manually, which increases the number of operating steps. It is also inconvenient for the driver to operate in the way of dri...
