    Abstract: Disclosed is a sound-producing candle assembly comprising a candle and a base which are detachable from one another. One candle can be removed from the base and replaced by another. In one embodiment, each candle contains an optical guide, which conveys light from the flame to an optical switch, the switch in turn activating a sound-generating system, rendering a stored sound audible. Each candle may contain an alignment guide, which maintains alignment between the optical guide and the optical switch. Each candle may also contain one or more fire stops to prevent the candle from burning beyond a certain point. The assembly may allow a user to choose among several sounds to be heard when the candle is lit. The assembly may also allow a user to record sound.
