Stylophone



The Stylophone is a miniature analog electronic keyboard musical instrument played with a stylus. Invented in 1967 by Brian Jarvis, it entered production in 1968, manufactured by Dubreq.

Some three million Stylophones were sold, mostly as children's toys, but they were occasionally used by professional musicians such as John Lennon, Kraftwerk and David Bowie.

The Stylophone consists of a metal keyboard made of printed circuit board and is played by touching it with a stylus. Each note on the keyboard is connected to a voltage-controlled oscillator via a different-value resistor, and touching the stylus to the keyboard thus closes a circuit. The only other controls are a power switch and a vibrato control on the front panel beside the keyboard, and a tuning potentiometer on the rear.

The Stylophone was available in standard, bass and treble variants, but the standard version was the most common. There was also a larger version called the 350S with more notes on the keyboard, various voices, a wah-wah effect that was controlled by moving the hand over a photosensor and two styluses.

In the mid-1970s, a new model appeared that featured simulated wood on the speaker panel and a volume control. However, production of the Stylophone ceased in 1975.

Entertainer Rolf Harris served for several years as the Stylophone's advertising spokesman in the United Kingdom and appeared on many "play-along" records sold by the manufacturer.[
