Japanese violin production company Alte Kobo has developed a violin as a speaker of an audio system. The speaker can reproduce sounds, such as the voices of musical instruments and even humans.
When in use, the Violin Player –which can even be played like a violin– has to be connected to a stereo or other sound source.
A violin produces sounds when vibrations of the strings resonate between its front and back plates through its string-stretching units. The Violin Player converts audio signals into vibrations then transmits them to its string-stretching units to reproduce original sounds.
