Abstract
An illumination level/musical tone converter is described which is suitable for incorporation into a miniature electronic device such as an electronic wristwatch, whereby the pitch of musical notes emitted by an acoustic output device can be varied as desired by the user varying the amount of illumination reaching a light sensor, e.g. by partially shading the sensor using a finger. Melodies can be composed in this way, and means can be provided for memorizing such melodies, which can be subsequently reproduced, e.g. to provide an audible alarm indication.
