Abstract: This application relates to a method and an apparatus for controlling a sound receiving device based on a dual-mode audio three-dimensional code and a method and an apparatus for parsing a control signal of a sound receiving device based on a dual-mode audio three-dimensional code. The method includes: receiving an operation instruction and encoding the operation instruction as a digital vector; obtaining a first audio three-dimensional code corresponding to a preset speech signal, and encoding the digital vector into the first audio three-dimensional code to obtain a second audio three-dimensional code; and converting the second audio three-dimensional code into a speech signal and sending the speech signal to a sound receiving device. In the method, operation convenience can be improved, and an instruction operation can be performed without arrangement of any additional module.
