Abstract

The invention relates to the technical field of loudspeakers and provides a method and a system for audio fidelity of a loudspeaker. The method comprises the following steps of monitoring a working process of the loudspeaker to obtain working condition parameters of the current loudspeaker, wherein the working condition parameters include loudspeaker temperature parameters and loudspeaker resistance parameters; calling frequency compensation values corresponding to the working condition parameters of the current loudspeaker according to a corresponding relation between the pre-generated working condition parameters of the loudspeaker and the frequency compensation values; and adopting the called frequency compensation values to carry out frequency weighted compensation on a power amplifier connected to the loudspeaker. According to the method and the system, a problem that one audio file has different playing effects at different time periods is solved, the tone quality of the loudspeaker is promoted and the high-quality audio-visual experience is provided for a user.

Description

technical field [0001] The invention belongs to the technical field of loudspeakers, in particular to a loudspeaker audio fidelity method and system. Background technique [0002] High-fidelity speaker audio output is a pursuit of speaker designers. During the continuous operation of the speaker, its internal temperature will gradually increase, and various operating parameters of the speaker will also change accordingly, such as the increase in the resistance of the voice coil inside the speaker High, diaphragm and Dome become soft, etc., resulting in changes in frequency response (FR). [0003] Therefore, the frequency response of the same speaker will change obviously when it starts working and after a period of time, that is, the same audio file plays different effects at different time stages, that is, there is audio distortion. Contents of the invention [0004] The object of the present invention is to provide a loudspeaker audio fidelity method and system, aiming ...
