A kind of car intelligent tuning equipment and method

Abstract

The present invention relates to the fields of intelligent tuning, car power amplifier and car refitting, especially a kind of car smart tuning equipment and method, including a high-sensitivity microphone, a tuning device and a digital power amplifier device, the digital power amplifier device includes a CPU circuit and a power supply module, and The digital-to-analog conversion circuit connected to the CPU circuit, the analog-to-digital conversion circuit and the debugging interface, the analog-to-digital conversion circuit is connected to the input interface, the digital-to-analog conversion circuit is connected to the power amplifier circuit, the power amplifier circuit is connected to the digital output interface, and the power module is connected to the digital The power supply interfaces of each circuit of the power amplifier device are connected; the high-sensitivity microphone and the debugging interface are respectively connected with the debugging equipment. Through the collection of audio signals in the car, intelligent software is used to repair and compensate the audio signal in the car, and adjust the output delay to achieve the function of automatic tuning. The invention further lowers the threshold for refitting and upgrading of the car audio system, saves the cost of upgrading and refitting, reduces the demand for human resources, and improves the efficiency of installation and debugging.

Description

technical field [0001] The invention relates to the field of intelligent tuning, automobile power amplifier and automobile refitting, in particular to an automobile intelligent tuning device and method. Background technique [0002] With the development of the automobile industry. Cars have become the main choice for people's daily travel. When driving, playing music is the entertainment method that has the least impact on the driver's sight and attention. It helps to relieve fatigue and tension during long-time driving, and has a certain refreshing effect, which helps to improve driving safety and driving. experience. [0003] Therefore, people's demand for in-car sound effects is also getting higher and higher. After the traditional in-car audio is installed, most low-end and middle-end models are not equipped with an independently adjustable power amplifier system, while the audio system of high-end models must be debugged by a professional tuning engineer to adjust th...
