[0029] In a preferred embodiment, the ceramic bottle 1 has multiple wiring connections. When a frequency division group of inductor L and capacitor C is used, ten positive and one negative outputs of a single audio power amplifier are connected to the frequency divider 2, and then two positive and negative wires of the treble, midrange, and bass are drawn out from the frequency divider 2 to be connected to the treble, midrange, and bass power amplifier group 3.
