Claim Text:
1. A method for transmitting data using sound signals, adapted for a sound transmitting apparatus having a sound-producer array and a processor to transmit data to a sound receiving apparatus having a sound-receiving array, comprising: defining by the processor a plurality of basic tones and a plurality of control tones by using a plurality of sound frequencies within a sound frequency range, wherein each of the basic tones corresponds to a character, and each of the control tones corresponds to an order of the basic tones; converting by the processor a plurality of transmitting characters in the data to be transmitted into the corresponding basic tones; determining by the processor the control tone based on the order of the transmitting characters; transmitting by the processor the converted basic tones and the determined control tone to the sound receiving apparatus by using the sound-producer array; and converting by the sound receiving apparatus the received basic tones into the transmitting characters by using the sound-receiving array, and determining the order of the transmitting characters based on the received control tone, so as to recover the data.
