FIELD: computing; counting.
SUBSTANCE: invention relates to computer technology, namely to triggering execution of operation instruction. Method for triggering execution of operation instruction comprises detecting an electric signal generated on a signal input line of an audio output device on a local machine body, wherein the signal input line of the audio output device is a line between a power amplifier and the audio output device, the power amplifier comprises an additional feedback signal input terminal and an additional feedback signal output terminal, an electrical signal is received from the input signal line of the audio output device, converting the electrical signal on the signal input line from an analog signal to a digital signal, transmitting the converted digital signal to the central processor, determining the first operation instruction corresponding to the first signal characteristic according to the relationship between the pre-stored signal characteristics and the operation instructions, when the detected electrical signal satisfies said first signal characteristic from the pre-stored signal characteristics, said first operation instruction is executed.
EFFECT: technical result is the increase efficiency of triggering execution of operation instruction.
