电子小提琴与常规小提琴的无线载波传输演示

Demonstration of wireless transition of electric violin and normal violin

小提琴可分解成拉弦系统和共振箱系统．在拉弦系统中,弦的振动被变为电声信号,以电磁波的形式发射到空中．在共振箱系统中,由调频接收器接收信号,经电声转换后驱动共鸣箱发声．改装后的电子小提琴可用于物理实验演示教学及小提琴弦振动和共鸣箱的频谱分析．

The violin is divided into string system and resonance box system. In string system, the string vibration is converted to electro-acoustic signal, and is emitted to the air in the form of electro-magnetic wave. In the resonance box system, the signal is received by frequency-modulated receiver. Through electro-acoustic conversion, the resonance box is driven to make sound. The repacked violin can be used in demonstration experiment of physical teaching and used in frequency spectrum analysis for string vibration and resonance box of violin.
