the third contact is connected to a ground pin of the speaker.
The first contact, the second contact and the third contact can be arranged in a concentrated mode, and accordingly the arrangement sequence of the earphone socket and the charging earphone socket is correspondingly controlled and converted according to the arrangement sequence of the Bluetooth earphones. For example, when the bluetooth headset is set according to the order of the first contact, the second contact and the third contact, the switching headset socket is correspondingly set with the fourth contact, the fifth contact and the sixth contact in turn, and the charging headset socket is set with the seventh contact, the eighth contact and the ninth contact in turn.
As shown in fig. 2, the structure of the switching earphone socket is shown, the switching earphone socket includes a fourth contact, a fifth contact and a sixth contact, the fourth contact is connected to the audio data line, the fifth contact is connected to the power supply of the switching earphone socket through a pull-up resistor, and the sixth contact is connected to the ground line of the switching earphone socket.

The serial communication interface can be a UART interface, and the Bluetooth module can be debugged and the like by connecting the second contact with the UART interface.
The direct current cuts off the module and is used for cutting off direct current's voltage to when making first contact link to each other with the socket power of the earphone socket that charges, cut off the socket power of the earphone socket that charges, can not cause the speaker noise to appear, perhaps influence bluetooth headset's life.
Preferably, the direct current blocking module comprises a passive direct current blocking module and/or a passive band-pass filter, so as to improve the quality of the output audio of the bluetooth headset. As shown in fig. 1, the dc blocking module includes a passive blocking module and a passive band pass filter, and the influence of the dc power supply can be filtered by the passive blocking module, and the influence of other noises other than the audio signal can be filtered by the passive band pass filter.
The Bluetooth module comprises a dormant state and a working state, when the Bluetooth headset is in a wireless use state, the Bluetooth module is in the working state, and when the Bluetooth headset is in a wired use state, the Bluetooth headset can be in the dormant state.
Whether the bluetooth module is in the wired use state or the wireless use state can be judged through detection of the contact voltage of the second contact. For example, whether the voltage of the second contact is greater than a certain voltage value may be detected. When the voltage of the second contact is larger than a certain voltage value, the Bluetooth headset is in a wired playing state, the controllable switch is controlled to be switched on by the Bluetooth module, the Bluetooth module works normally, the audio signal is received by the Bluetooth module, and the audio signal is transmitted to the loudspeaker to be played through the controllable switch.
The controllable switch, namely the active low-resistance switch, the control pin of the controllable switch is connected with the Bluetooth module, and the opening and closing of the controllable switch can be controlled through the Bluetooth module.
The power source may be a rechargeable battery, such as a rechargeable lithium battery or the like.

When the Bluetooth headset is connected with the charging headset socket shown in fig. 3, the Bluetooth module controls the active low-resistance switch to be disconnected, and the direct-current partition module partitions the connection between the loudspeaker and the socket power supply of the first contact, so that the charging current cannot affect the loudspeaker end, and the phenomenon that the current enters the loudspeaker to emit noise is avoided. The second contact is suspended or is a serial communication interface and can be used for debugging the Bluetooth module.
As shown in fig. 4, a method for switching between a bluetooth headset and a wired headset based on a bluetooth headset and a switching headset jack according to an embodiment of the present invention includes:
in step S401, when it is detected that the second contact of the bluetooth headset is connected to the fifth contact of the switching headset jack, the controllable switch is controlled to be in an off state and the bluetooth module is turned off.
In the embodiment of the invention, when the second contact of the Bluetooth headset is detected to be connected to the socket power supply of the switching headset socket, the controllable switch is controlled to be in the off state, so that the Bluetooth headset is in the wireless playing state and the Bluetooth module is turned off, and the Bluetooth headset can save more energy.
In particular, the fifth contact connected to the second contact may be connected to the power supply of the switching headset jack by means of a pull-up resistor.
Preferably, the first voltage value of the second contact is detected, and when the first voltage value is greater than the preset voltage value, the controllable switch is controlled to be in an off state and the Bluetooth module is turned off, so that the Bluetooth headset is more energy-saving. Further preferably, the first voltage value of the second contact is detected, and when the ratio of the first voltage value to the voltage value of the bluetooth headset is greater than a preset threshold value, for example, when the ratio of the first voltage value to the voltage value of the bluetooth headset is greater than 2, the controllable switch is controlled to be in an off state and the bluetooth module is turned off, so that the bluetooth headset is further accurately controlled to be turned on, and the utilization efficiency of the bluetooth headset is improved.
Here, the preset voltage value is smaller than the voltage of the fourth contact, so that whether the switching headset socket is connected with the bluetooth headset can be accurately and effectively judged. In addition, the preset threshold value can be flexibly set according to the use habit of a user, and when the multiple is larger, the longer the time length of the Bluetooth headset in the wireless playing state is, the more the electric quantity of the power supply in the Bluetooth headset is consumed.
In step S402, the fourth contact sends the audio data to the speaker for playing through the first contact;
in the embodiment of the invention, the first contact can send the audio signal to the loudspeaker through the passive direct current blocking module and the passive band-pass filter in the direct current blocking module so as to improve the quality of the output audio.
In step S403, the third contact is connected to the ground line of the sixth contact.
