ABSTRACT:
A wind-activated audio-generating apparatus includes a sound-generating circuit and a wind switch having multiple contacts that are suspended from a support. When subjected to an air current, the contacts of the wind switch randomly strike one another and create a momentary electrically conductive path for an electrical signal. The electrical signal is applied to the sound-generating circuit, which is configured to generate an audio effect, such as a birdcall, in response thereto. The sound-generating circuit can also be configured to selectively generate an audio effect based on the occurrence of a predetermined condition, such as the detection of daylight.
