摘要： A novel information providing system for providing various information to a terminal is proposed. The information providing system 1 according to an embodiment of the present invention includes a transmitter 10 for transmitting various information as information on sound pressure vibration, a portable telephone 20 serving as a terminal for receiving various information, and a server 50 connected through the Internet 40 to the transmitter 10. The configuration is characterized in that various information is transmitted as sound through the air serving as a medium from the transmitter 10 to the portable telephone 20.

摘要： Where information is to be conveyed as acoustic waves, embodiments of the present invention provide a transmitter capable of causing acoustic waves that convey information to be not easily perceived by the human ear. A transmitter, being an apparatus that converts various types of encoded information into acoustic wave(s) in the audible spectrum and carries out transmission thereof, comprises microphone(s) that cause ambient sound(s) from location(s) at which acoustic wave(s) is/are transmitted to be input as ambient sound signal(s); peak frequency detector(s) that detect, within ambient sound signal(s), peak frequency or frequencies of major constituent(s) of ambient sound(s); carrier wave generator(s) that generate carrier waves at a plurality of frequencies that are natural number multiples of peak frequency or frequencies and that can be used to mask ambient sound(s); and modulator(s) that modulate a plurality of carrier waves with baseband signal(s).
