Mobile learning system large classroom with non-electric sound amplifying function

The invention provides a mobile learning system large classroom with a non-electric sound amplifying function. According to the technical scheme of the mobile learning system large classroom with thenon-electric sound amplifying function, the problems that as for a mobile learning system large classroom, sound dispersing is uneven and poor in effect, consequently, the school teaching effect is poor, and interaction between teachers and students are unsmooth are solved. The mobile learning system large classroom mainly comprises wooden sound reflecting plates. Under the situations of taking full consideration of the sound absorbing effect and the reflecting effect, classroom steps, a platform, walls, a ceiling, seats, a floor and windows are integrally designed, thus harmony and unity of the sound pressure level, sound field uniformity and reverberation time of sound in the classroom are achieved, the effects which cannot be achieved through single design are achieved, and the new function that the sum of one, one and one is greater than three is achieved. After the test, when a teacher gives a lesson, the sound pressure level of students at the rear rows is increased, and the sound field uniformity of the front rows and the rear rows of the classroom are great; during questioning and answering of the students, the sound pressure level of the other students and the teacher arealso increased by about 25 decibels, the reverberation time in the classroom is in an expected value of about 0.83 second, and the auditory environment effect of the classroom is good.
