Embodiment 1

[0043] Embodiment 1: as figure 1 As shown, a device that uses sound as a carrier to trigger information interaction, which includes a data sending unit, a data receiving unit and a control unit;

[0044] The data sending unit is used to send the sound signal generated by the control unit;

[0045] The data receiving unit is used to receive external effective sound signals and transmit the signals to the control unit;

[0046] The device for triggering information interaction using sound as a carrier of the present invention also includes an auxiliary communication unit for large data volume communication.

[0047] When the amount of information exchange between the two parties is large, such as pictures, video files, music files, etc., the auxiliary communication unit can be used for information exchange, and the connection through the voice as the carrier is used to transfer the IP or IP required when the auxiliary communication unit is turned on. Physical address informati...

Embodiment 2

[0058] Embodiment 2: as image 3 As shown, the difference between this embodiment and Embodiment 1 is: a method for triggering information interaction using voice as a carrier, using a master-slave response connection method, which includes the following steps:

[0059] Step 1: The control unit of the active communication party modulates the preamble to the specified audio frequency point and sends it out through the speaker;

[0060] Step 2: The other party of the communication receives the signal through the microphone, and decodes it by the control unit to obtain the preamble;

[0061] Step 3: The control unit of the other party of communication selects a frequency point of a sound different from that of the active communication party as the carrier, and modulates the ACK signal to this frequency point to send out;

[0062] Step 4: The microphone of the active communication party receives the ACK (ACKnowledge Character, a transmission control character sent by the receivin...

Embodiment 3

[0073] Embodiment 3: as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is: a method for triggering information interaction using sound as a carrier, using a master-master single-frequency point connection method, which includes the following steps:

[0074] Step 1: The control units of both communication parties randomly or directionally select a sound audio point as the carrier;

[0075] Step 2: The control units of both communication parties modulate the preamble into their selected audio frequency points and send out;

[0076] Step 3: The control units of both communication parties judge the similarities and differences between the frequency points of the received signal and the frequency points of their own transmitted signals, and return to step 1 if they are the same; if they are different, proceed to the next step;

[0077] Step 4: The control units of both communication parties decode the received signal to obtain the preamble;

[0078] S...

Abstract

The invention relates to a device for triggering information interaction by using sound as a carrier. The device comprises at least one data sending unit, at least one data receiving unit, at least one auxiliary communication unit, and at least one control unit, wherein the data sending unit is used for sending sound signals produced by the control unit, the data receiving unit is used for receiving external effective signals and transmitting the signals to the control unit, the auxiliary communication unit is used for mass quantity data communication, and the control unit is used for processing signals collected back by the data receiving unit, that is, storing, decoding, computing, and controlling wideband signals collected back by the data receiving unit, judging whether the received signals are effective or not, and producing sound signals at multiple frequency points. The invention further relates to a method for triggering information interaction by using sound as the carrier. The invention has such beneficial effects that the device and the method do not need extra cost, realize communication without blind spots, and become more convenient and more user-friendly.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a device and method for using sound signals as carriers to trigger communication and using analog sound channels as channels for information interaction. Background technique [0002] With the advancement of science and technology, especially the rapid development of wireless communication technology in recent years, wireless communication plays an increasingly important role in people's lives. Simplified operation, high speed, and no blind spots in communication are strong requirements of users for current wireless communication products, especially portable products. Although the most popular communication methods such as Bluetooth and WiFi (wireless fidelity, a wireless networking technology) are fast and convenient, they also have their own defects and cannot meet the growing needs of users. For example, during the Bluetooth technology connection process, the us...
