PURPOSE:To provide the above device suitable for use in particles etc., where the lower part of a candle is provided with both temperature detector and audio emitter in an integral manner and a thermal conductive means within the candle to automatically emit melodies when ignited. CONSTITUTION:When a candle 1 is ignited, the heat of the flame is transmitted, through the hollow space in the core 11 (thermal conductive means), to the thermosensor of the temperature detector 5, and the resulting signal from said detector 5 is sent to a comparator 6, from which an actuation signal is outputted and sent to the melody IC 7, thus a melody is emitted from a speaker 9 through the resulting output from said IC. When the candle is extinguished,the detection temperature at the detector 5 falls below a specified temperature; therefore, emission of the actuation signals from the comparator 6 is stopped, thus also stopping emission of the melody from the speaker 9. |
