Wireless communications system, wireless microphone transmission apparatus, and wireless receiving apparatus

A wireless communications system for transmitting and receiving a radio microphone signal carrying a voice signal indicative of voice information and a tone signal indicative of data information, comprising:

• a wireless microphone transmission apparatus for transmitting said radio microphone signal carrying said voice signal indicative of voice information and said tone signal indicative of data information, said data information including a plurality of data types;
• and
• a wireless receiving apparatus for receiving said radio microphone signal carrying said voice signal and said tone signal transmitted by said wireless microphone transmission apparatus;
• said wireless microphone transmission apparatus including:
• a voice inputting unit for inputting said voice information therethrough to generate said voice signal indicative of said voice information;
• a data inputting unit for inputting said data information therethrough;
• a data string generating unit for judging said data type of said data information inputted by said data inputting unit, determining a bit length of a data string in response to said data type, and generating said data string having said bit length on the basis of said data information inputted by said data inputting unit;
• a tone signal generating unit for generating said tone signal indicative of said data information on the basis of said data string generated by said data string generating unit;
• a mixing unit for mixing said voice signal generated by said voice inputting unit and said tone signal generated by said tone signal generating unit to generate a microphone signal carrying said voice signal and said tone signal;
• a modulating unit for modulating said microphone signal carrying said voice signal and said tone signal generated by said mixing unit with a carrier signal to generate said radio microphone signal carrying said voice signal and said tone signal;
• a transmission unit for transmitting said radio microphone signal carrying said voice signal indicative of said voice information and said tone signal indicative of said data information modulated by said modulating unit, therethrough, and
• said wireless receiving apparatus including:
• a receiving unit for receiving said radio microphone signal carrying said voice signal indicative of said voice information and said tone signal indicative of said data information transmitted by said wireless microphone transmission apparatus;
• a demodulating unit for demodulating said radio microphone signal carrying said voice information and said tone signal received by said receiving unit to generate said microphone signal;
• a voice signal filtering unit for filtering said voice signal indicative of said voice information therethrough from said microphone signal generated by said demodulating unit;
• a tone signal filtering unit for filtering said tone signal therethrough from said microphone signal generated by said demodulating unit;
• a data information computing unit for computing said data information on the basis of said tone signal filtered through by said tone signal filtering unit;
• a data information outputting unit for outputting said data information acquired by said data information computing unit, therethrough;
• and
• a voice information outputting unit for outputting said voice information on the basis of said voice signal filtered through by said voice signal filtering unit, therethrough, in accordance with said data information outputted by said data information outputting unit.
