(57) Abstract Objective As for this device, the sensor which detects the change of the light intensityIt has to be the device which, the light intensity around the aforementioned sensor fixed standardWhen being below or above, sound and music and sound are regeneratedru thing is designated as the principal feature. Constitution As for sensor 12, light intensity change around voltage andTo convert to the change of electric current, as for the decision circuit 13, aforementioned voltage andIs low, it decides whether it is high change of electric current by comparison with reference level, or,The signal of ON or OFF is output. As for output circuit 14,From the aforementioned decision circuit 13 trust of ON or the OFF which is outputTo be controlled by the number, the aforementioned output circuit 14 sound and music and soundBy making the circuit configuration which is regenerated, with ON sound and musicAnd it regenerates sound, halts with OFF.
