Therefore, on the one hand, when the MOS tube is cut off, the USB function of the electronic device can be disconnected physically, so that the USB host of the electronic device is smoothly closed, and continuous loss of the electric quantity of the electronic device in the process (such as the first mode) that the Type-C interface connection is not used is avoided. 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 requirement of a user, and the electric quantity loss can be reduced by disconnecting the electric connection when the earphone is not used, so that the electric quantity loss of the electronic equipment is controlled from the whole use process, and the power consumption of the electronic equipment is saved.
Optionally, as shown in fig. 1, in an embodiment of the present application, the Type-C interface includes: CC1 pin and SBU pin, this MOS pipe is N type MOS pipe.
The drain electrode of the N-type MOS tube is connected with the CC1 pin, the source electrode of the N-type MOS tube is grounded, and the grid electrode of the MOS tube is connected with the SBU pin.
Optionally, as shown in fig. 1, in an embodiment of the present application, the Type-C interface further includes a pull-down resistor.
The source electrode of the N-type MOS tube is connected with a pull-down resistor and is grounded through the pull-down resistor.
Optionally, the level of the SBU pin of the earphone Type-C interface is determined by the level of the output interface of the electronic device. For example, GPIO (General purpose input/output) interfaces of electronic devices.
Optionally, in the embodiment of the present application, the corresponding relationship between the output level of the SBU pin of the earphone Type-C interface and the on-off state of the N-Type MOS transistor is as follows:
under the condition that the earphone is in the first mode, the SBU pin outputs a low level to control the cut-off of the N-type MOS tube.
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 the embodiment of the present application, the first mode is a mute mode, specifically, when the earphone is physically connected to the electronic device through the Type-C interface, the earphone does not start the audio playing mode; a mode in which the audio play mode is started but the volume is zero is also possible.
Optionally, in the embodiment of the present application, the second mode is a non-mute mode, and 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 MOS transistor may be a P-channel MOS transistor or an N-channel MOS transistor; or can be an enhancement type MOS tube or a depletion type MOS tube. The embodiment of the application is not particularly limited, and the level of the grid electrode of the MOS tube can be adaptively adjusted according to the specific type of the MOS tube.
In the embodiment of the present application, as shown in fig. 1 and fig. 2, the enhanced N-type MOS transistor Q1 is taken as an example for illustration, which does not constitute a specific limitation in the embodiments of the present application.
Optionally, in this embodiment of the present application, the function of the enhanced N-type MOS transistor Q1 shown in fig. 1 and fig. 2 is equivalent to a current switch, and the working principle is as follows: the level high and low connected to the gate through the SBU controls the on or off of Q1. Specifically, the first case: when the level of the SBU connected to the grid electrode is high, the voltage between the grid electrode and the source electrode is greater than or equal to the threshold voltage, the MOS tube Q1 is conducted, the current is grounded through the CC1 and the pull-down resistor R1, and at the moment, the electronic equipment is electrically connected with the earphone, and the electronic equipment can use the function of the earphone (such as playing audio). Second case: when the level of the SBU connected to the grid electrode is low, the voltage between the grid electrode and the source electrode is smaller than the threshold voltage, the MOS tube Q1 is cut off, the pin CC1 is in a suspended state, at the moment, the electronic equipment is electrically connected with the earphone and disconnected, and the electronic equipment is physically connected with the earphone but is electrically disconnected with the earphone.
For example, as shown in fig. 2, the electronic device is physically connected to the earphone through a Type-C interface, and an enhancement N-Type MOS transistor Q1 is added between a CC1 pin of the earphone and a pull-down resistor R1 (the resistance value of the pull-down resistor R1 is specifically determined according to actual use). The specific connection mode is as shown in fig. 2, the drain electrode of the MOS tube Q1 is connected with the CC1 pin, the source electrode of the MOS tube Q1 is grounded through the pull-down resistor R1, and the grid electrode of the MOS tube Q1 is connected with the SBU pin of the earphone. When the earphone is in a mute mode (i.e., a first mode), the CPU of the electronic device outputs a low level to the SUB pin through the GPIO (General-purpose input/output), the voltage between the gate and the source is smaller than the threshold voltage, the MOS transistor Q1 is turned off, the CC1 pin is in a suspended state, at this time, the electronic device is electrically disconnected from the earphone, although the electronic device is physically connected to the earphone, at this time, the electronic device is electrically disconnected from the earphone, so that the USB function of the electronic device is physically disconnected, thereby smoothly turning off the USB host of the electronic device, and avoiding continuous loss of the electric quantity of the electronic device. When the earphone is in the non-mute mode (i.e. the second mode), the level of the CPU of the electronic device output to the SUB pin through the GPIO is high, the voltage between the grid electrode and the source electrode is larger than the threshold voltage, the MOS tube Q1 is conducted, the current is grounded through the CC1 and the pull-down resistor R1, at the moment, the electronic device is electrically connected with the earphone, and the electronic device can play audio by 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 CC1 pin and the pull-down resistor, the earphone may control the on or off of the MOS transistor Q1 according to the level of the SBU connected to the gate of the N-type MOS transistor Q1, so that in the case that the earphone is in the first mode, the N-type MOS transistor is controlled to be turned off; and under the condition that the earphone is in the second mode, controlling the conduction of the N-type MOS tube. And further, the electric quantity loss of the electronic equipment is controlled from the whole using process of the earphone, so that the power consumption of the electronic equipment is saved.
Optionally, another possible connection mode is to use a P-type MOS transistor, specifically, in the case that the MOS transistor is a P-type MOS transistor, the source of the P-type MOS transistor is connected to the CC1 pin, the drain of the N-type MOS transistor is grounded, and the gate of the MOS transistor is connected to the SBU pin. Not shown in the drawings of the embodiments described below.
Optionally, in this embodiment of the present 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 the embodiment of the present application, the corresponding relationship between the output level of the SBU pin of the earphone Type-C interface and the on-off of the 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.
Under the condition that the earphone is in the second mode, the SBU pin outputs a low level to control the conduction of the P-type MOS tube.
