The image P1 has the mark M1 and the mark M2, and the calculating unit 110 is based on the image P1. The flag M1 calculates the first parameter, so that the audio playback unit 230 plays the first audio according to the first parameter. In the present invention, the first parameter can be used to adjust the volume, the angle adjustment of the directional speaker or the multi-channel according to different requirements. select.

The communication device 10 can be internally provided with the audio generating device 120 to generate the first audio. The communication device 10 has the first main audio, and can be the audio stored in the communication device 10 or the network streaming audio. The position of the mark M1 in the image P1 is distinguished by the first The parameter is an adjusted channel parameter such as one of a left channel parameter, a right channel parameter, a subwoofer channel parameter, a left rear channel parameter, and a right rear channel parameter, and the audio generating device 120 is based on the first parameter. The first primary audio is converted to the corresponding channel to become the first audio, and the transmitting unit 130 transmits the first audio to the speaker device 20 to cause the audio playback unit 230 to play the first audio.

In addition, the speaker device 20 can also have a built-in audio generating device 220. The speaker device 20 has a second main audio, which can be an audio stored in the speaker device 20 or a network stream audio. The first parameter is a flag.
