ABSTRACT:
These small, inexpensive ornaments and novelties emit music and other sounds (such as simulated voice) when exposed to light, and can be placed out-of-doors in a garden. Being light-powered, they can operate for an essentially indefinite time, even though unattended.
Each such ornament or novelty consists of a thematically configured body and a three-element working module sealed in a watertight can. It has no input keyboard or other terminal, and no display panel or other electronic or visual data output, except the audio output.
Elements are (1) a circuit, preprogrammed to produce electronic oscillations corresponding to a tune or other sounds preestablished at manufacture, (2) a speaker receiving the oscillations and emitting the sounds, and (3) a solar panel powering the circuit. The speaker shuts off if light is inadequate for completely correct operation, and otherwise is amplitude modulated by the light level.
The decorative body, the detailed programming of the circuit, and the particular tune or other sounds are coordinated in theme.
