(57) Abstract (Modified) Objective It is installed in the Christmas tree, the lamp aroundSynchronism to music, the chestnut which can make blinking operation doThe lamp device for sumasutsuri is offered. Constitution Possessing the buffer amplifier and the lock state detectorThe PLL circuit which it does, the time constant circuit and the time when it is jointed to this fixedWith the output of the output circuit and this circuit which are jointed to several circuits the dotThe lamp which is burnt as one channel multiple chiyanneru to provide, the entry edge of each channel in one signal entry dot formaTo input the electric music signal into the forming and this entry dot, each chiyaSelf-propelled frequency and kiyapuchiyare of PLL circuit of nneruWidth of nji, those it does not overlap in each PLL circuitAt the same time in frequency distribution state way it is inside audible frequency band, optionAs so it configurates beforehand, each PLL circuit husband Various lock stateOut from the husband Various lock state detector by doing,With the signal which depends on the time constant circuit and stabilizes the power signal the output circuitDrive, the lamp for the Christmas tree is blinked.
