Abstract: A wireless speaker system includes a wireless remote control model car and a docking speaker. The wireless remote control model car includes a wireless transceiver, a microcontroller unit connected to the wireless transceiver, and an audio line-out/data interface connected to the wireless transceiver. The docking speaker includes an audio line- in/data interface being configured to be connectable with the audio line-out/data interface. The wireless receiver/transceiver is configured to modulate and format electrical signals from the microcontroller unit and the audio line-out/data interface into radio or infrared signals, to transmit the radio or infrared signals to the docking speaker, and to demodulate and format radio or infrared signals from a wireless remote/music source into electrical signals to be received by the microcontroller unit and the audio line-out/data interface.
