ABSTRACT:
A simulated wood burning sound system, including an electronic circuit that provides the "crackle" sound of a combustible wood fire. The system includes a programmed electronic sound chip that stores a recorded memory of wood burning sound. A volume control potentiometer adjusts the audio volume of the sound being transmitted through a speaker and is adjustable to simulate a range of sound effects from a quite fire to a roaring fire. A temperature sensitive sensor for detecting heat or a light sensitive sensor controls automatic startup and shutdown. In addition, a power switch has a permanent "on" position for testing the unit and for applications, such as a simulated fire, where a sensor is not applicable. A plastic housing protects the circuitry and provides a mounting base.
