At this time, the detection signal changes from a high level to a low level, and the detection signal is sent to the main control chip; the voltage on the HS_DET pin of the main control chip is short-circuited to the ground through the unlocked detection switch 30, and when the detection signal is identified to change from a high level to a low level, the main control chip determines that the play instruction is to start playing according to the detection signal; the amplifier component 60 is used to determine that the play audio result is to start playing audio according to the play instruction when receiving the play instruction determined by the main control chip. At the same time, the main control chip transmits the play instruction to the audio playback device through the amplifier component 60 to start playing audio. The premise for the audio playback device to perform the processing is that the audio playback device is in the turned-on state; the main control chip obtains audio data from the audio playback device through the amplifier component 60, and realizes the transmission of audio data between the earphone and the metal pin 20 and the contact core 41 inserted into the contact hole 13.

[0068] The headphone plug 40 is pulled out of the four-core balanced socket assembly 1, specifically, the shell 42 is pulled out of the slot 18, and the contact core 41 is pulled out of the contact hole 13. At this time, when the shell 42 is pulled out, the movable rod 32 moves to a position away from the main control board 50 until the headphone plug 40 is completely pulled out of the slot 18, and the movable rod 32 completely rebounds to its original state; that is, the unlocked detection switch 30 is converted from a closed state to a normally open state, and generates the detection signal. At this time, the detection signal changes from a high level to a low level, and the detection signal is sent to the main control chip; the voltage of the main control chip on the HS_DET pin is the power supply voltage of +3.3VDD, and when it is recognized that the detection signal changes from a low level to a high level, it determines that the play instruction is to pause the play according to the detection signal; the amplifier assembly 60 is used to determine that the play audio result is to pause the play audio according to the play instruction when receiving the play instruction determined by the main control chip. The main control chip is used to send a corresponding power-off instruction to the power supply component of the device to disconnect the power supply of the amplifier component 60 when recognizing that the detection signal changes from a low level to a high level, thereby saving resources.

[0069] Through the above embodiments, it can be known that the device can detect the change of the detection signal generated by the headphone plug 40 being inserted into or pulled out of the socket body 10 through the lock-free detection switch 30, so that the main control chip determines the play instruction according to the identified detection signal to control the amplifier component 60 to turn on or off the audio playback process. Therefore, the device can directly identify the insertion or removal of the headphone plug 40 and make corresponding processing for the insertion or removal, which improves the interactivity between devices and improves the playback efficiency.

[0070] For the convenience and brevity of description, the specific technical content of the device described above can refer to the corresponding technical content in the aforementioned component embodiment, which will not be repeated here.

[0071] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
