| These are driven by a delicate varable speed controlled motor to vary the volume of sound produced.
The vibrato is produced by shaking the tail-piece of the violin with an electro-magnet. The violin
can reproduce 64 notes, and it is accompanied by a 44 note piano - just half the number of keys
found on a normal piano keyboard. The iron frame of the piano is shield shaped, the supporting of the
bass strings in the centre, and the treble strings on either side resulting in this shape which
evens the stress on the frame and assists in maintaining the piano's tuning. It is
coin operated, the mechanism being capable of accomodating up to 15 coins. Since most of the
music rolls have five tunes on them, it can play the five tunes three times giving music for an hour
or so. Coins may be added at any time - even in a coin box remotely situated on the cafè
wall. |
