Abstract

The invention relates to a rechargeable intelligent sound box power supply management system. Audio signals received from the outside are amplified and played through a loudspeaker. The charging circuit is used for charging the battery pack module, the switching circuit is used for turning on or turning off the power supply of the intelligent sound box, the boosted circuit boosts the voltage of the battery pack module and outputs the boosted voltage to the power amplifier, and the signal sampling feedback circuit is used for collecting power signals of the power amplifier in real time. The single-chip microcomputer circuit outputs a PWM signal to the charging circuit according to the current of the power input interface, and is used for adjusting the charging current and controlling the charging time of the battery pack module. And meanwhile, the output voltage of the booster circuit is controlled according to the acquired real-time power signal, so that the output voltage changes in real time along with the change of the power amplifier. The power supply management system provided by the invention not only considers the working efficiency of the battery pack module, but also considers the music playing effect of the loudspeaker.

Description

technical field [0001] Embodiments of the present invention relate to the fields of smart audio, mobile phones, smart home and electronic information, and in particular to a smart audio power management system applied to batteries such as lithium batteries, dry batteries, and lead-acid batteries. Background technique [0002] At present, in the fields of smart audio, mobile phones, and smart homes, with the rapid development of the Internet of Things, smart phone Bluetooth technology, Wifi technology, and artificial intelligence, outdoor sports, mobile communications, and intelligent voice-controlled electronic portable devices are developing rapidly. The demand for these portable electronic devices is increasing, and the battery-powered system consisting of a battery and a DC power boost power management is indispensable for these portable electronic devices. Lithium batteries in the prior art are limited by technology and technology, so the capacity of the battery cannot b...
