Fig. 1 is a schematic structural diagram of an electronic device assembly according to an embodiment of the present invention. The electronic device assembly includes a terminal device 10 and a digital headset 20.

The terminal device 10 includes a first communication interface 110, a processor 120, a first switch 130 and a power supply 140, wherein the processor 120 is connected to the first communication interface 110, and specifically, the processor 120 is connected to a first insertion identification pin of the first communication interface 110. The processor 120 is further connected to a control terminal of the first switch 130, and the power supply 140 is connected to a power supply pin of the first communication interface 110 through the first switch 130. The first switch 130 may be switched in a variety of states.

The digital headset 20 includes a second communication interface 210, the second communication interface 210 being adapted to the first communication interface 110, and the second communication interface 210 being detachably connected to the first communication interface 110.

The above first communication interface 110 is a universal serial bus Type C interface, i.e., a USB Type-C interface. The above second communication interface 210 is also a universal serial bus Type C interface, i.e., a USB Type-C interface. Specifically, the USB Type-C interface of the terminal device 10 may be a USB Type-C plug, i.e., a USB Type-C plug (also referred to as a USB Type-C male). Correspondingly, the USB Type-C interface of the digital headset 20 may be a USB Type-C socket, i.e., a USB Type-C socket (also referred to as a USB Type-C female connector). However, the present application is not limited to this, and the usb C-type interface of the terminal device 10 may also be a usb C-type socket, and only the usb C-type interface of the digital earphone 20 and the usb C-type interface of the terminal device 10 can be matched to realize connection.

It can be understood that the first communication interface 110 has 24 terminals in total, and can be inserted in a forward direction or a reverse direction, and the transmission speed is fast, and the interfaces have no directionality, so that the situation of wrong insertion can be avoided in use, and the failure rate is effectively reduced. The D + pin and the D-pin in the first communication interface 110 are pins for compatibility with the legacy USB standard, and the D + pin and the D-pin are the above first insertion identification pins. The VBUS pin in the first communication interface 110 is a power supply pin. The CC pin in the first communication interface 110 is a channel configuration pin, which is the following second insertion identification pin. As for other pins in the first communication interface 110, reference may be made to the prior art, and detailed description thereof is omitted here. The second communication interface 210 of the digital headset 20 and the first communication interface 110 of the terminal device 10 have the same structure, and at the same time, as shown in fig. 1, the CC pin of the digital headset 20 is grounded through a pull-down resistor, so that the terminal device 10 can recognize the digital headset 20 as an OTG device.

In this embodiment, as shown in fig. 1, when the first communication interface 110 is connected to the second communication interface 120, the processor 120 controls the first switch 130 to be in the first state, and the power supply 140 is turned on with the power pin of the first communication interface 110 to supply power to the digital headset 20.

In this embodiment, the power source is usually a battery, and the power voltage ranges from 3.2V to 4.45V, which is the battery voltage.

As shown in fig. 1, the power voltage VBAT is output to the digital headset 20 through the power pin, that is, the terminal device 10 provides the battery voltage 3.2V to 4.45V to the digital headset 20 for power supply. Namely, the battery voltage of 3.2V to 4.45V is directly supplied to the digital earphone 20 for power supply, so that the consumption of redundant electric quantity during the operation and standby of the digital earphone 20 is avoided, the power consumption during the operation and standby of the digital earphone 20 is further reduced, and the standby time of the digital earphone 20 is prolonged.

According to the embodiment, the electronic device assembly relates to a terminal device and a digital earphone, the terminal device comprises a power supply, a first communication interface, a processor and a first switch, the digital earphone comprises a second communication interface, and when the processor detects that the first communication interface is connected with the second communication interface, the first switch is controlled to be in a first state, the power supply is conducted with a power supply pin of the first communication interface to supply power to the digital earphone, namely, power supply voltage is output to the digital earphone through the power supply pin. That is, when the terminal device is connected to the digital earphone, the terminal device directly outputs the power voltage to the digital earphone for power supply, which is equivalent to reducing the voltage supplied to the digital earphone, thereby reducing the power consumption of the digital earphone during operation and standby without affecting the function of the earphone.

In one embodiment, as shown in fig. 1, the terminal device 10 further includes a boost module 150. A first input terminal of the voltage boosting module 150 is connected to the power supply 140, a second input terminal of the voltage boosting module 150 is connected to the processor 120, and an output terminal of the voltage boosting module 150 is connected to a power pin of the first communication interface 110 through the first switch 130.

In this embodiment, when the first communication interface 110 is connected to an OTG device other than the digital headset 20, the processor 120 controls the first switch 130 to be in the second state, and the voltage boosting module 140 is conducted with the power pin of the first communication interface 110 to supply power to the OTG device.

It can be understood that the terminal device 10 boosts the power voltage of 3.2V to 4.45V to 5V through the boost module 150, and at this time, if the external device connected to the terminal device 10 is an OTG device other than the digital headset 20, the 5V voltage is provided to the external device for supplying power, so that normal operation of the other OTG devices other than the digital headset 20 can be ensured.

It is understood that the first communication interface 110 further has the above second insertion identification pin, and correspondingly, as shown in fig. 2, the terminal device 10 further includes a detection module 160. The input terminal of the detection module 160 is connected to the second insertion identification pin, and the output terminal of the detection module 160 is connected to the third input terminal of the boosting module 150.

The second insertion identification pin is a CC pin in the above usb type-C interface.

Specifically, when the first communication interface 110 of the terminal device 10 is connected to an external device, the detection module 160 may detect whether the external device is an OTG device through the second insertion identification pin, that is, the CC pin, and when the detection module 160 detects that the external device is an OTG device, the processor 120 detects whether the OTG device is the digital headset 20 through the first insertion identification pin, that is, the D + pin and the D-pin, so as to further improve the detection accuracy.

In one embodiment, as shown in FIG. 1, the first switch 130 is a single pole, double throw switch that includes a moving contact, a first stationary contact, and a second stationary contact. The movable contact is connected to a power pin of the first communication interface 110, the first stationary contact is connected to the power supply 140, and the second stationary contact is connected to an output terminal of the voltage boosting module 150.

In one example, as shown in fig. 1, in the case that the first communication interface 110 is connected with the second communication interface 210, the processor 120 controls the movable contact to be connected with the first stationary contact, so that the power supply 140 is conducted with the power pin of the first communication interface 110 to supply power to the digital headset 20.

As can be seen from the above, the power source terminal voltage VBAT is output to the digital earphone 20 through the power source pin, that is, the electronic device 10 provides the battery voltage 3.2V to 4.45V to the digital earphone 20 for power supply. On one hand, the processor 120 controls the boosting module 150 to stop working, and the boosting module 150 is not required to consume redundant electric quantity, so that the standby time of the terminal device 10 is prolonged. On the other hand, compared with the case that the battery voltage is boosted to 5V by the boosting module 150 and then supplied to the digital earphone 20 for power supply, the power consumption of the digital earphone 20 during operation and standby is avoided, the power consumption of the digital earphone 20 during operation and standby is further reduced, and the standby time of the digital earphone 20 is prolonged.

In one example, in the case that the first communication interface 110 of the terminal device 10 is connected to an OTG device other than the digital headset 20, the processor 120 controls the movable contact to be connected to the second fixed contact, and the voltage boosting module 150 is conducted to a power pin of the first communication interface 110 to supply power to the OTG device.

As can be seen from the above, the terminal device 10 boosts the voltage of the power supply terminal from 3.2V to 4.45V to 5V through the boost module 150, and then supplies the boosted voltage to other OTG devices to supply power, so that the normal operation of other OTG devices except the digital earphone 20 can be ensured.

In this embodiment, the first switch is used as a single-pole double-throw switch, and the power consumption of the digital earphone during operation and standby can be reduced only by controlling the single-pole double-throw switch through the processor.

In one embodiment, as shown in fig. 2, the terminal device 10 further includes a voltage adjusting module 170, and the voltage adjusting module 170 is connected between the power source 140 and the first switch 130. Specifically, the voltage adjustment module 170 may be connected between the power source 140 and the first stationary contact of the first switch 130.

In this embodiment, when the first communication interface 110 is connected to the second communication interface 210, the processor 120 controls the first switch 130 to be in the first state, and the voltage adjustment module 170 is conducted with the power pin of the first communication interface 110 to supply power to the digital headset 20, that is, the power voltage is output to the digital headset 20 through the voltage adjustment module 170 and the power pin of the first communication interface 110.

The voltage regulation module 170 includes a low dropout regulator LDO or a dc converter DCDC. The LDO has the advantages of good stability, fast load response and low efficiency. The direct current converter DCDC has the advantages of high efficiency, wide input voltage range and slow load response.

The outputting of the above power terminal voltage to the digital headset 20 through the voltage adjusting module 170 and the power pin may further include: the voltage adjusting module 170 selects the minimum working voltage of the digital headset 20, and adjusts the voltage of the power source terminal according to the minimum working voltage of the digital headset 20, so as to output the adjusted voltage of the power source terminal to the digital headset 20 through the power source pin.

Specifically, as shown in fig. 2, in the case that the first communication interface 110 is connected to the second communication interface 210, the processor 120 controls the movable contact to be connected to the first fixed contact, and the voltage adjustment module 170 is conducted to a power pin of the first communication interface 110 to supply power to the digital headset 20.

As can be seen from the above, as shown in fig. 2, the voltage adjustment module 170 may select the minimum operating voltage required by the digital earphone 20 during operation, so as to ensure that the power consumption of the digital earphone 20 is always small, and compared with directly providing the power terminal voltage of 3.2V to 4.45V to the digital earphone 20 for power supply, the power consumption of the digital earphone 20 during operation and standby is further reduced, and the standby time of the digital earphone 20 is increased.

In one embodiment, as shown in FIG. 2, the boost module 150 includes: a booster circuit 151 and a power supply control circuit 152, an input terminal of the booster circuit 151 being connected to the power supply 140; a first input terminal of the power control circuit 152 is connected to the output terminal of the voltage boost circuit 151, a second input terminal of the power control circuit 152 is connected to the processor 120, an output terminal of the power control circuit 151 is connected to the second stationary contact of the second switch 130, and a third input terminal of the power control circuit 152 is connected to the output terminal of the detection module 160.

The above boosting circuit 151 may be an inductor.

In one example, as shown in fig. 2, in the case that the processor 120 detects that the first communication interface 110 is connected to the second communication interface 120, the processor 120 controls the movable contact to be connected to the first stationary contact, and the voltage adjustment module 170 is conducted to a power pin of the first communication interface 110 to output a power voltage to the digital headset 20 through the power pin. Here, the power supply control circuit 152 controls the booster circuit 151 to stop operating, thereby reducing power consumption of the terminal device 10 and increasing the service life of the terminal device 10.

The embodiment of the invention also provides terminal equipment which can be mobile phones, tablet computers, notebook computers, palmtop computers, wearable equipment and the like.

As shown in fig. 3, the terminal device 10 includes a first communication interface 110, a processor 120, a first switch 130, and a power supply 140, wherein the processor 120 is connected to the first communication interface 110, and specifically, the processor 120 is connected to a first insertion identification pin of the first communication interface 110. The processor 110 is further connected to a control terminal of the first switch 130, and the power supply 140 is connected to a power supply pin of the first communication interface 110 through the first switch 130.

The first insertion identification pin may be a D + pin and a D-pin.

In this embodiment, as shown in fig. 1, when the first communication interface 110 is connected to the second communication interface 210, the processor 120 controls the first switch 130 to be in the first state, and the power supply 140 is conducted with the power pin of the first communication interface 110 to supply power to the digital headset 20.

In this embodiment, the power source is usually a battery, and the power voltage ranges from 3.2V to 4.45V, which is the battery voltage.

According to the embodiment, a terminal device is provided, where the terminal device includes a power supply, a first communication interface, a processor, and a first switch, and in a case where the processor detects that the first communication interface is connected to the second communication interface of the digital headset, the first switch is controlled to be in a first state, and a power supply end is conducted with a power pin of the first communication interface to supply power to the digital headset, that is, a power supply end voltage is output to the digital headset through the power pin. Namely, when the terminal equipment is connected with the digital earphone, the terminal equipment directly outputs the voltage of the power supply end to the digital earphone for supplying power, which is equivalent to reducing the voltage supplied to the digital earphone, thereby reducing the power consumption of the digital earphone during working and standby under the condition of not influencing the function of the earphone.

It can be understood that the terminal device 10 boosts the voltage at the power supply end of 3.2V to 4.45V to 5V through the boost module 150, and at this time, if the external device connected to the terminal device 10 is an OTG device other than the digital earphone 20, the 5V voltage is provided to the external device for supplying power, so that the normal operation of the other OTG devices other than the digital earphone 20 can be ensured.

As can be seen from the above, the power voltage VBAT is output to the digital headset 20 through the power pin, that is, the electronic device 10 provides the battery voltage 3.2V to 4.45V to the digital headset 20 for power supply. On one hand, the processor 120 controls the boosting module 150 to stop working, and the boosting module 150 is not required to consume redundant electric quantity, so that the standby time of the terminal device 10 is prolonged. On the other hand, compared with the case that the battery voltage is boosted to 5V by the boosting module 150 and then supplied to the digital earphone 20 for power supply, the power consumption of the digital earphone 20 during operation and standby is avoided, the power consumption of the digital earphone 20 during operation and standby is further reduced, and the standby time of the digital earphone 20 is prolonged.

As can be seen from the above, the terminal device 10 boosts the voltage of the power supply terminal from 3.2V to 4.45V to 5V through the boost module 140 and provides the boosted voltage to other OTG devices for power supply, so that the normal operation of other OTG devices except the digital earphone 20 can be ensured.
