Example Embodiment
[0038] Example one
[0039] figure 1 It is a flowchart of a method for returning response messages provided by Embodiment 1 of the present invention, see figure 1 , The method of this embodiment includes:
[0040] Step 101: Receive information sent by the information sender, and generate a response message corresponding to the message;
[0041] Step 102: Process the response message, generate and send a corresponding sound wave signal, so that the sound wave relay receives and decodes the response message and sends it back to the information sending end.
[0042] The method in this embodiment is executed by an information receiving end, and the information receiving end may specifically be a terminal device such as a mobile phone. In this embodiment, the information receiving end is a mobile terminal as an example.
[0043] In the method of this embodiment, after the information receiving end receives the information sent by the information sending end, it triggers the generation of a c...

[0051] Example two
[0052] figure 2 This is a flowchart of another method for returning a response message provided in the second embodiment of the present invention. The method in this embodiment is executed by the information sending end, see figure 2 , The method of this embodiment includes:
[0053] Step 201: Send information to the information receiving end, and wait to receive a response message;
[0054] Step 202: Receive a response message returned by the sound wave relay;
[0055] Wherein, the response message returned by the acoustic wave relay is: the acoustic wave relay is decoded after receiving the acoustic wave signal generated and sent by the information receiving end according to the response message corresponding to the information.
[0056] In the method of this embodiment, after the information receiving end receives the information sent by the information sending end, it triggers the generation of a corresponding response message, and sends the response message t...
Example Embodiment
[0062] Example three
[0063] image 3 This is a flowchart of yet another response message return method provided in the third embodiment of the present invention, which is executed by the acoustic relay, see image 3 , The method of this embodiment includes:
[0064] Step 301: Receive a sound wave signal generated and sent by an information receiving end processing a response message, where the response message is a corresponding response message generated after the information receiving end receives the information sent by the information sending end;
[0065] Step 302: Process the received acoustic wave signal, and decode to obtain the response message;
[0066] Step 303: Return the response message obtained by decoding to the information sending end.
[0067] When the acoustic relay receives the acoustic signal, it can first use the spectral subtraction filter and the wiener filter to reduce the noise, and then decode the noise-reduced acoustic signal.
[0068] In the method of this ...
