Frequency modulation listening oral language teaching system

Abstract

A frequency modulation listening oral language teaching system comprises a grade end frequency modulation transmitting system and a frequency modulation receiving end, the grade end frequency modulation transmitting system comprises an intelligent broadcast controller and a frequency modulation transmitting subsystem, the frequency modulation transmitting subsystem comprises a frequency modulationtransmitter, a feeder line and an antenna, and the frequency modulation receiving end is an earphone. The frequency modulation transmitter is composed of a transmitter power supply module, a transmitter main controller module, a transmitter display and key module, an audio signal input preprocessing module and a signal modulation and high-frequency signal amplification module, the audio output end of the intelligent broadcast controller is connected with the audio input end of the frequency modulation transmitter, and the radio frequency output end of the frequency modulation transmitter is connected with an antenna through the feeder line to transmit frequency modulation signals. The system is easy and convenient to install and easy to maintain in the later period, the defect of insufficient individuation of the grade transmitting end is overcome by playing spoken listening learning courseware through the grade transmitting end and the grade receiving end, and teachers can arrange learning content by themselves according to the characteristics of the carried grades, such as content with high listening difficulty in fast class and basic content listening in poor class.

Description

technical field [0001] The invention relates to a teaching system based on wireless frequency modulation transmission and wireless frequency modulation reception, especially an English listening and speaking learning system for the purpose of centralized training and learning in schools. Background technique [0002] With the gradual implementation of reforms in English senior high school entrance examinations and college entrance examinations across the country, the requirements for students' English listening and speaking skills are gradually increasing, and many schools are trying to deal with and solve them. At present, there are several solutions to the above needs: [0003] One is to use the hardware facilities that the school has built, such as the voice classroom, and use them in turn. However, due to the differences in the economic levels of the first-tier, second-tier, third-tier, and fourth-tier cities across the country, the hardware facilities of most schools a...

Problems solved by technology

If there is no language environment for learning a language, the learning effect will be greatly reduced

[0004] The second is that some schools are still using the most primitive method, that is, each teacher carries a tape recorder to play in the classroom during class. This method can only practice listening, and the sound quality effect through the speaker is difficult for students to hear clearly. In English pronunciation, voiceless consonants, voiced consonants, continuous pronunciation, etc., the volume heard by students sitting in the front row and students sitting in the back row is also very different, and during the playback process, adjacent classes will also be affected

These links may cause the best project to fail to be realized

[0006] In summary, there are still many problems in the above-mentioned methods for foreign language listening and speaking training in primary and secondary schools: students have little time to learn English listening, and are limited by hardware conditions, so they cannot learn freely anytime and anywhere

[0008] Although the platform based on the network and big data has powerful functions, the investment is huge. The school needs to invest tens of millions to build a network platform and server
