Synchronized beat notification system and master device and slave device for use therewith

A master device for a synchronized beat notification system for providing synchronized beat notification through slave devices to a plurality of users having the respective slave devices and participating in synchronization with a common rhythm, the master device comprising:

• a beat input unit to which a user inputs a beat with arbitrary timing;
• a master radio communication unit for transmitting, as radio information, to the slave devices the beat inputted to the beat input unit together with identification information corresponding to information identifying the master device;
• and
• a master housing containing therein the beat input unit and the master radio communication unit.

A system of slave devices for providing synchronized beat notification transmitted by a master device to a plurality of users having the respective slave devices and participating in synchronization with a common rhythm, each of the slave devices comprising:

• a slave radio communication unit for receiving information corresponding to the synchronized beat notification transmitted by the master device and including identification information corresponding to information identifying the master device;
• a beat notification unit for performing notification of a beat to the user in accordance with the synchronized beat notification received by the slave radio communication unit, the slave radio communication unit extracting the identification information from the received information and controlling the beat notification unit to perform beat notification only when the extracted identification information coincides with identification information on a master device intended to become a communication partner with the slave device;
• and
• a slave housing containing therein the slave radio communication unit and the beat notification unit.
