Abstract

The invention provides an intelligent sound effect power amplifier chip arranged in an intelligent mobile device. The intelligent sound effect power amplifier chip is electrically connected with an external integrated circuit and a horn in the intelligent mobile device, and the intelligent sound effect power amplifier chip comprises an integrated circuit bus interface, an integrated circuit built-in audio bus interface, a startup device, a register and a sound effect module. The integrated circuit bus interface and the integrated circuit built-in audio bus interface are used forming a communication connection with the external integrated circuit and the intelligent sound effect power amplifier chip. The startup device is used for starting the intelligent mobile device. After the intelligent mobile device is started, the register imports an audio application scene and sound effect parameters in the external integrated circuit and temporarily stores the audio application scene and the sound effect parameters. The sound effect module reads and operates the audio application scene and the sound effect parameters corresponding to the audio application scene stored in the register according to a sound effect scene instruction so as to generate a sound source signal and send the sound source signal through the horn.

Description

technical field [0001] The present invention relates to an intelligent sound effect power amplifier chip and a switching method of the sound effect power amplifier, in particular to an intelligent sound effect power amplifier chip capable of storing multiple sound effect parameters and a method capable of switching multiple sound effect parameters. Background technique [0002] Smart Audio amplifier chip (Smart Audio amplifier chip) is a kind of amplifying the input audio signal to drive the micro-speaker to make sound, and in the process of driving, it adopts the protection algorithm to protect the temperature and other physical quantities of the speaker in real time, so that the temperature and other The physical quantity is within the tolerance range of the speaker, which ensures that the speaker works in a safe state. [0003] In order to make the speaker work in a safe state and get the best sound effect, the smart sound effect power amplifier chip needs to be configure...
