The invention discloses a sound production system and method for automatically compensating for an audio path transfer function. The system comprises M monitoring microphones with pre-amplifiers, M passive sound production units, a power amplification circuit with M paths of input and output, and a compensation controller with M paths of input and output. According to the invention, the vacancy inthe audio system market is made up, and audio channel distortion caused by factors such as sound field environment, sounding unit characteristics, simulation characteristics and the like can be reduced, thereby improving the sound quality. The system is simple to use and operate; a compensation filter can be generated and digitally filtered through simple calibration, so acoustic signal distortion caused by factors such as a sound field environment, analog circuit characteristics and sounder characteristics is reduced, complex acoustic debugging and balancing steps are omitted while high-fidelity acoustic experience is brought to a user, and a large amount of time and energy are saved.
Description
technical field [0001] The invention relates to the field of audio systems, in particular to a sounding system and method for automatically compensating the transfer function of an audio path. Background technique [0002] With the improvement of people's living standards, consumers have higher and higher requirements for the sound quality, sound image, and fidelity of audio systems. There are multiple layers of distortion, which are caused by factors such as analog circuits, sound unit characteristics, and sound field environment. How to quickly, conveniently and effectively reduce the distortion of the above-mentioned audio channel is an urgent problem to be solved in the industry at present. Contents of the invention [0003] The purpose of the present invention is to solve the problems mentioned above in the background technology section through a sounding system and method for automatically compensating the transfer function of the audio path. [0004] For reaching ...
