Abstract

The invention relates to a sound amplifying system, which is characterized in that sound signals are acquired through a sound acquisition module, amplification processing is performed through a signal amplification module, then the amplified sound signals are converted into audio signals by a conversion module, the audio signals are subjected to power amplification through a power amplification module and then sent to a processor, and an echo feedback inhibition module is used for performing full-band feedback so as to inhibit self-excited whistlers of the audio signals. The processor outputs the audio signals processed by the feedback inhibition module to an external interface module, and the external interface module outputs the audio signals. Therefore, the audio signals processed by the sound amplifying system are free of self-excited whistlers and high in fidelity.

Description

technical field [0001] The invention relates to a sound reinforcement system, in particular to a sound reinforcement system with large sound reinforcement range and high fidelity. Background technique [0002] The teacher's voice is vulnerable to injury during teaching and there will be discomfort. In order to better convey the teaching content and not affect our students' normal lectures, they will use teaching loudspeakers to improve the quality of teaching, and at the same time can effectively protect the voice. On the one hand, it is easy to manage, and on the other hand, it helps students practice listening. However, the current existing loudspeakers are prone to howling, and the sound pickup range is small, the external interference sound is large, the sound amplification range is not large enough, and the fidelity is not enough. Contents of the invention [0003] Based on this, it is necessary to provide a sound reinforcement system with large sound amplification r...
