In the event that an electrical connection is established, a signal may be communicated between the headset and the electronic device (e.g., a first signal and a second signal, described below), and the electronic device may control the headset to output audio. When the electrical connection is disconnected, the USB function of the electronic equipment is disconnected physically, signals cannot be transmitted between the electronic equipment, and therefore the electronic equipment can smoothly close the USB host function of the electronic equipment.

It should be noted that specific functions of the codec module and the earphone microphone are described in the following embodiments, which are not repeated herein.

Optionally, in this embodiment of the present application, the working mode of the headset includes: a first mode and a second mode.

On the other hand, the earphone can be controlled by the control module according to the current earphone mode to disconnect or establish the electric connection of the electronic equipment, so that the electric connection can be established to use the earphone when necessary according to the use requirements of users, the electric loss can be reduced by disconnecting the electric connection when the earphone is not used, the electric loss of the electronic equipment is controlled in the whole using process, and the power consumption of the electronic equipment is saved.

Optionally, in this embodiment of the application, the output level of the SBU pin of the earphone Type-C interface corresponds to the on-off relationship of the N-Type MOS transistor as follows:

under the condition that the earphone is in the first mode, the SBU pin outputs low level to control the cut-off of the N-type MOS tube.

And under the condition that the earphone is in the second mode, the SBU pin outputs high level to control the conduction of the N-type MOS tube.

Optionally, in this embodiment of the application, the first mode is a non-silent mode, specifically, when the earphone is physically connected to the electronic device through the Type-C interface, the earphone starts an audio playing mode and plays audio.

Optionally, in the embodiment of the present application, the enhancement-type N-MOS transistor Q1 shown in fig. 1 and fig. 2 functions as a current switch, and the operation principle is as follows: the level high or low connected to the gate through the SBU controls the Q1 to turn on or off. Specifically, the first case: when the level of the SBU connected to the gate is high, the voltage between the gate and the source is greater than or equal to the threshold voltage, the MOS transistor Q1 is turned on, the current is grounded through the CC1 and the pull-down resistor R1, and at this time, the electronic device is electrically connected to the earphone, and the electronic device can use the function of the earphone (e.g., playing audio). In the second case: when the level of the SBU connected to the grid is low level, the voltage between the grid and the source is less than the threshold voltage, the MOS transistor Q1 is cut off, the CC1 pin is in a suspended state, the electronic equipment is electrically disconnected with the earphone at the moment, and the electronic equipment is physically connected with the earphone, but the electronic equipment is electrically disconnected with the earphone at the moment.

Specifically, as shown in fig. 2, the drain of the Q1 of the MOS transistor is connected to the pin CC1, the source of the Q1 of the MOS transistor is grounded through the pull-down resistor R1, and the gate of the Q1 of the MOS transistor is connected to the pin SBU of the earphone. When the earphone is in a mute mode (i.e., a first mode), a level output to the SUB pin by a CPU of the electronic device through a General-purpose input/output (GPIO) pin is a low level, a voltage between a gate and a source is smaller than a threshold voltage, a MOS transistor Q1 is turned off, a CC1 pin is in a floating state, the electronic device is electrically disconnected from the earphone at this time, and the electronic device is physically connected to the earphone, but the electronic device is electrically disconnected from the earphone at this time, so that a USB function of the electronic device is physically disconnected, a USB host of the electronic device is smoothly turned off, and continuous power loss of the electronic device is avoided. When the earphone is in the non-mute mode (i.e., the second mode), the level output to the SUB pin by the CPU of the electronic device through the GPIO is a high level, the voltage between the gate and the source is greater than the threshold voltage, the MOS transistor Q1 is turned on, the current is grounded through the CC1 and the pull-down resistor R1, and at this time, the electronic device is electrically connected to the earphone, and the electronic device can play audio using the earphone.

It can be understood that, in the embodiment of the present application, since the N-type MOS transistor Q1 is added between the pin CC1 and the pull-down resistor, the earphone can control the on/off of the N-type MOS transistor Q1 according to the level of the SBU connected to the gate of the N-type MOS transistor Q1, so that when the earphone is in the first mode, the off of the N-type MOS transistor is controlled; and controlling the conduction of the N-type MOS tube under the condition that the earphone is in the second mode. And then from the whole use control electronic equipment power consumption of earphone, practice thrift electronic equipment's power consumption.

The following examples are not shown in the drawings.

Optionally, in this embodiment of the application, the Type-C interface further includes a pull-up resistor, that is, the CC1 pin is connected to the source of the P-Type MOS transistor through the pull-up resistor.

Optionally, in this embodiment of the application, a corresponding relationship between an output level of an SBU pin of the earphone Type-C interface and an on-off state of a CC1 pin Type MOS transistor is as follows:

under the condition that the earphone is in the first mode, the SBU pin outputs high level to control the cut-off of the P-type MOS tube.

And under the condition that the earphone is in the second mode, the SBU pin outputs low level to control the conduction of the P-type MOS tube.
