Sound amplification system for teaching

Abstract

The invention discloses a teaching sound amplification system, which comprises a mobile terminal (1) and a sound amplification terminal (2) which are connected, and is characterized by further comprising a sound signal processor I (3), a sound signal processor II (4) and a sound amplification decibel tester (5) arranged below the sound amplification terminal (2), wherein the sound amplification decibel tester (5) is connected with the mobile terminal (1); The mobile terminal (1) is composed of a microphone (11), a sound processor (12) connected with the microphone (11) and used for convertingaudio signals received by the microphone (11) into digital signals, a CPU (13) connected with the sound processor (12), and a signal transmitter (14) connected with the CPU (13). The volume of the sound box can be automatically adjusted according to the volume of the sound box, so that the volume is appropriate, harsh noise is generated when the sound amplification system has small faults, the volume of the sound box can be automatically adjusted, and discomfort of students is reduced. And the volume of the sound box can be increased according to classroom noise, which is very convenient.

Description

technical field [0001] The invention relates to the field of teaching electrical appliances, in particular to a teaching sound amplification system. Background technique [0002] Education is the foundation of a country, and it is also the top priority of the future development of the motherland. In education, the quality of teachers' teaching in the classroom largely determines the status of students' education. With the development of the economy, traditional classrooms have developed from small classrooms with 40-50 people to large classrooms with more than 100 people. Therefore, teaching loudspeakers have entered people's field of vision. [0003] However, most teaching loudspeakers require teachers or specialized personnel to adjust the volume, and when the church is too large, it is difficult for teachers to know whether the students in different areas can hear the loudspeakers clearly, or whether it is because the surrounding noise is too loud, resulting in The volu...

Problems solved by technology

[0003] However, most teaching loudspeakers require teachers or specialized personnel to adjust the volume, and when the church is too large, it is difficult for teachers to know whether the students in different areas can hear the loudspeakers clearly, or whether it is because the surrounding noise is too loud, resulting in The volume of the loudspeaker cannot be heard clearly, and at the same time, a small fault in the loudspeaker will emit a harsh noise of large decibels. The teacher needs to adjust it by himself, causing the teacher to be distracted, and the students need to wait for the harsh noise to disappear, which affects the mood of listening to the class.
