Abstract
A device for playing music includes a maglev unit and a base unit. The maglev unit outputs a first sound signal based on a physical signal corresponding to an original sound signal. The base unit provides the physical signal to the maglev unit via a first wireless transmission, and outputs a second sound signal based on the original sound signal. The base unit includes a maglev control module, a power supply module and a processor. The maglev control module generates a magnetic force according to a first current to make the maglev unit float on the base unit. When the first current is continuously within a predetermined current range for a predetermined time duration, the processor controls the power supply module to output the first current, and to supply an electrical energy to the maglev unit via a second wireless transmission that is different from the first wireless transmission.
