Demonstration of wireless transition of electric violin and normal violin
Hao Wei · Physics Experimentation · 2006
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 a-nalysis for string vibration and resonance box of violin.
