The earphone 200 is pluggably connected to the portable electronic device 100 and plays audio output by the audio playback module 10 through a speaker 210. The microphone 220 is used to record environmental sounds and user voices.

Referring to FIG. 2, the audio playing method of the audio playing system 1 according to a preferred embodiment of the present invention includes the following steps:

In step 01, the portable electronic device 100 is connected to the earphone 200, the audio playback module 10 outputs audio to the earphone 200, and the speaker 210 plays the audio. In this embodiment, when the portable electronic device 100 is in a call, the audio is a voice call; when the portable electronic device 100 is in a call, When the electronic device 100 is playing music, the audio is music audio.

In step 02, the positioning module 20 determines the position of the portable electronic device 100.

In step 03, the processor 50 determines whether the portable electronic device 100 is located at a preset position, such as a user's residence or office, according to the location. When the processor 50 determines that the user is currently at the preset position, execute step 06; when the processor 50 determines that the user is not currently at the preset position, execute step 05.

In step 04, the processor 50 calculates a moving speed of the portable electronic device 100 according to a position change of the portable electronic device 100.

In step 05, the processor 50 determines whether the moving speed is within a preset range. The preset range corresponds to the current exercise state of the user of the portable electronic device 100, such as walking, running, or cycling. It can be understood that different exercise states may correspond to different preset ranges. If it is determined that the moving speed is within the preset range, the user is in the motion state, and step 06 is performed; otherwise, return to step 02.

In step 06, the radio module 40 or the microphone 220 records ambient sounds, and the processor 50 identifies the special audio in the ambient sounds. It can be understood that ambient sound can be recorded by one or both of the radio module 40 and the microphone 220 at the same time. When the portable electronic device 100 is in a call state, ambient sound can be recorded by the radio module 40, and the user's call voice can be received through the microphone 220. It can be understood that when the processor 50 determines that the special audio does not appear in the ambient sound, the audio playback module 10 continues to output the current audio to the headset 200 for playback.

In step 07, the processor 50 determines whether the special audio appears in the ambient sound. If it is determined that the special audio occurs, step 08 is performed; otherwise, return to step 02.

In step 08, the processor 50 controls the audio playback module 10 to stop playing audio.

In step 09, the audio playback module 10 outputs a warning audio to the earphone 200, and the earphone 200 plays the warning audio through the speaker 210 to remind the user to pay attention.

In step 11, the portable electronic device 100 outputs the ambient sound recorded by the radio module 40 to the earphone 200, and the speaker 210 plays the ambient sound. In this embodiment, when the portable electronic device 100 is in a call state, the ambient sound can be recorded through the radio module 40, and the user's call voice can be recorded through the microphone 220.

In step 12, the earphone 200 records the ambient sound through the microphone 220, and the speaker 210 plays the ambient sound.

It can be understood that steps 11 and 12 are the implementation manners of the two embodiments. The earphone 200 can record the ambient sound through the radio module 40 and the microphone 220, and play the ambient sound through the speaker 210.

In another embodiment, steps 02, 03, 04, and 05 can be omitted, that is, when the speaker 210 is playing audio, the radio module 40 or the microphone 220 directly records ambient sounds without judging the user's current position and current State of motion.

It can be understood that the portable electronic device 100 stores the special audio data. The processor 50 compares the ambient sound with the stored special audio data to identify and determine the special audio.

When a user of the audio playback system 1 of the present invention listens to music or a call through the headset 200, the portable electronic device 100 pauses the current audio according to the special audio of the environmental sound, and then outputs the playback environmental sound to remind the user to pay attention to the current Environment and improve safety.
