String music electronic auxiliary teaching system

Abstract

The invention discloses a string electronic aided teaching system, consisting of a teacher control platform, a teacher earphone, a teacher microphone, an aided teaching device, student earphones and a simulation microphonic musical instrument code; the teacher control platform is provided with n button switches which are arranged in parallel and the quantity of which is corresponding to the number of students; n signal ports of the n button switches are connected with the network port of the aided teaching device; the interface of the aided teaching device is connected with the student earphones and the simulation microphonic musical instrument code which is arranged on a traditional string instrument; the teacher control platform is connected with the teacher earphone and the teacher microphone; the micro-computer chip EP3C50F of the aided teaching device processes the audio signals of the simulation microphonic musical instrument code; subsequently, the signals are transmitted to the teacher earphone by the button switches; after being processed and amplified by the teacher microphone and the circuit in the teacher control platform, the voice of the teacher is transmitted to the student earphones to be monitored by the button switches so as to monitor the musical performance of a certain student or guide the student to practise.

Description

technical field [0001] The invention relates to a stringed musical instrument, in particular to an electronic auxiliary teaching system for stringed music using microelectronic technology and network technology. Background technique [0002] At present, traditional stringed instruments, such as erhuqin, violin, matouqin, banhuqin, pendant huqin, Jinghuqin, etc., all use the vibration of the strings to transmit the vibration frequency to the qin skin through the bridge. The function of the "membrane" expands the amplitude many times, and then achieves the effect of pronunciation through the resonance of the resonance box-qin tube. When beginners practice playing with traditional stringed instruments, they will inevitably make loud and unpleasant sounds. In fact, even if the performance level reaches a certain level, noise pollution will occur, especially as a musical instrument for teaching. The generated sound interferes with the teaching of adjacent classrooms. When multip...

AI Technical Summary

Problems solved by technology

When beginners practice playing with traditional stringed instruments, they will inevitably make loud and unpleasant sounds. In fact, even if the performance level reaches a certain level, noise pollution will occur, especially as a musical instrument for teaching. The generated sound interferes with the teaching of adjacent classrooms. When multiple students practice together, they can also interfere with each other

At present, teachers generally use one-to-one teaching mode, which has low teaching efficiency and high learning cost.
