The present invention is applied to the technical field of sound wave communications. Provided are a sound wave sending method, receiving method, sending device and receiving device and system. The sound wave receiving method comprises: receiving, by several channels of a sound wave apparatus, sound wave communication access information in a fixed frequency modulation manner, the sound wave communication access information comprising several preferred frequencies supported by several channels of a mobile terminal; after the sound wave communication access information is received, respectively establishing connections for the several channels and the several channels of the mobile terminal; extracting the several preferred frequencies, and respectively configuring the several preferred frequencies as sending frequencies and receiving frequencies of the several channels; sending, by the several channels, sound wave communication response information at the configured several preferred frequencies; and closing a processing thread of the sound wave communication access information, so as to shield the sound wave communication access information. The present invention also improves the stability of data communication while guaranteeing that the data communication is conducted between only two apparatuses in a sound wave system. |
