Abstract

The present invention relates to an FM broadcasting speaker system. In addition, the present invention relates to a method for transmit and receive frequency matching between a plurality of FM transmitters and a plurality of FM receivers used in the speaker system. The FM broadcasting speaker system according to the present invention comprises an FM broadcaster and an FM receiver player. The FM broadcaster comprises a radio transceiver and an FM transmitter, and is configured to process a signal received by the radio transceiver and output the processed signal by the FM transmitter. The FM receiver player comprises an FM receiver and a speaker, and is configured to process a signal received by the FM receiver and output the processed signal through the speaker. A signal received by the radio transceiver includes the identification number of the FM receiver player and the broadcasting frequency information of the FM transmitter. The FM broadcasting speaker system according to the present invention can receive, by an FM broadcaster, a multi-channel audio stream transmitted through a portable electronic device, such as a smartphone or a tablet PC, and simultaneously transmit the same to a plurality of FM receiver players. Therefore, the FM broadcasting speaker system can receive a multi-channel audio stream from a mobile phone via Bluetooth and output audio channel signals from a plurality of speakers without a time delay.
