Abstract
An electric violin has a combination of two sorts of vibration detectors for transverse vibration components and vertical vibration components, a low-pass filter connected to the vibration detector for the transverse vibration components and a high-pass filter connected to the vibration detector for the vertical vibration components, piezoelectric transducers connected in parallel to a signal processing system, or vibration detectors connected to filter circuits different in frequency characteristics for producing right-channel and left-channel signals so that the electric violin generate electric tones close to acoustic violin tones.
