Title:
ACOUSTIC COMMUNICATION SYSTEM, PAIRING METHOD FOR ACOUSTIC COMMUNICATION SYSTEM, AND ACOUSTIC COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/238396
Kind Code:
A1
Abstract:
In this acoustic communication system, a first communication device (101) comprises: a connection request signal generation unit (208) that generates a first acoustic signal for requesting connection to a plurality of second communication devices (102); a communication parameter notification signal generation unit (209) that generates a second acoustic signal for notifying the second communication device (102) of communication parameter information; a response signal detection unit (205) that detects a response signal transmitted from at least one second communication device (102) in response to the first acoustic signal via a first audio input means for converting the input acoustic signal; a connection destination determination unit (206) which determines the second communication device (102) of a connection destination on the basis of at least one response signal detected by the response signal detection unit (205) and which generates connection destination information for identifying the second communication device (102) of the connection destination; and a communication parameter determination unit (207) that determines the communication parameter information to be used for data communication with the second communication device (102) of the connection destination identified by the connection destination information. The communication parameter notification signal generation unit (209) generates the second acoustic signal using a spreading code compatible with the second communication device (102) identified by the connection destination information. The second communication device (102) comprises a pairing establishment determination unit which uses the spreading code for a signal obtained by converting the acoustic signal input from the first communication device (101) by a second audio input means to determine whether or not pairing with the first communication device (101) has been established and which, when the pairing is determined to have been established, acquires the communication parameter information included in the second acoustic signal input from the first communication device (101).
