PURPOSE:To attain brilliant and beautiful appearance and to stop a broadcast at power application state by arranging the primary and secondary coil of a frequency transformer to the upper part of a frame and a bottom in a bottle, suspending a speaker in a bottle operture by a suspension arm, and arranging a light emitting diode In the bottle. CONSTITUTION:The secondary coil 6 is placed so that the magnetic line of force on the primary coil 5 at the upper face of the frame 1 is made dense and the speaker 10 is arranged to a location offering excellent sound. A power supply 13 is inputted, the knob of a variable resistor 7 is turned to increase the sound volume, a frequency tuning dial is turned to match the frequency for channel selection, a desired broadcast is received by an antenna 3 and outputted from the speaker as sound. The light emitting diode 12 arranged in the inside of the bottle 2 and the top of the suspension arm 4 is lighted by sensing the high or low sound volume. In lifting up the bottle 2, the primary coil 5 and the secondary coil 6 are parted and no magnetic line of force between the coils is caused, the circuit is inoperative, no sound is outputted, and in descending the bottle 2, the sound is given again. Further, a desired sound effect is selected by adjusting the length of a chain 11 so as to adjust the position of the speaker 10 in the bottle 2.
