Abstract:
1. A wireless power transmission audio system comprising: a device on a transmitting end; and a loudspeaker which is associated with the device on the transmitting end, the wireless power transmission audio system being configured to transmit electric power and an audio signal wirelessly from the device on the transmitting end to the loudspeaker, wherein the device on the transmitting end includes: wherein the loudspeaker includes: wherein at least one of the device on the transmitting end and the loudspeaker includes an impedance adjusting circuit which is connected to the first or second resonant circuit and which changes an impedance value on a transmission line of the transmission signal according to the variation of the transmission signal that has been sensed by the detecting circuit, and wherein, when the impedance adjusting circuit changes the impedance value, the transmission signal adjusting circuit changes a signal waveform of the transmission signal at the device on the transmitting end.
