Problems solved by technology
[0003] However, this traditional speaker system has a fatal shortcoming, which is that it will cause mutual interference between classrooms.
Because in a teaching building, there must be many classrooms, and a loud speaker system will inevitably cause mutual interference between classrooms.

The invention relates to the technical field of intelligent teaching, and discloses an intelligent non-interference classroom loudspeaking method and system, and the system comprises a central processing unit, a microphone, a power controller, a sound box, a volume sensor group, a disturbing sound analysis module, and a sound wave transmitting module. The central processing unit is used for receiving data sent by the microphone, the volume sensor group and the disturbing sound analysis module and respectively controlling the power sensor and the sound wave transmitting module to work, and the microphone is used for collecting sound of personnel; through the volume sensors installed at different positions of the classroom in the volume sensor group, the volume of sound made by the classroom sound equipment can be monitored in real time, and when one or more monitoring values exceed a preset sound threshold value, the central processing unit can control the power controller to reduce the power of the sound equipment, so that the sound equipment is protected. Therefore, the sound of the sound equipment in the classroom does not interfere with other classrooms.
Description
technical field [0001] The invention relates to the technical field of smart teaching, in particular to a loudspeaker method and system for an intelligent non-interference classroom. Background technique [0002] The existing speaker system for classrooms is simply composed of microphones and speakers. This traditional speaker system allows the speaker (such as a teacher) to reach a certain volume without spending a lot of effort, which protects the speaker's voice well and reduces the probability of teachers getting occupational diseases. On the other hand, it can make students hear clearly and improve the effect of listening (no matter in small classrooms, medium classrooms, large classrooms, or super large lecture halls). [0003] However, this traditional speaker system has a fatal shortcoming, which is that it will cause mutual interference between classrooms. Because in a teaching building, there must be many classrooms, and a loud speaker system will inevitably caus...
