Hi Morgan. If you hear music with your Ion locator, it is not magic inside, it is only about bad design.
Another example: take one active audio amplifier and touch it with wire end on different circuit points. There is a quite reliable that after touch some points you will hear music (from your local radio station).
wire (or PCB copper track) + semiconductor element (working as diode) + voice element (buzzer) => primitive radio receiver.
Such random configurations can be found in most circuits. It is on designer to prevent such unintended radio receiving (eg. by RF shielding).
