The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides an electronic equipment assembly, which comprises terminal equipment and a digital earphone, wherein the terminal equipment can be mobile phones, tablet computers, notebook computers, palm computers, wearable equipment and other equipment.
Fig. 1 is a schematic structural diagram of an electronic device assembly according to an embodiment of the present invention. The electronic device assembly comprises a terminal device 10 and a digital earphone 20.
The terminal device 10 includes a power supply 140, a first communication interface 110, a processor 120, and a switch module 130, the switch module 130 including a first end, a second end, and a control end.
The processor 120 is connected to the first communication interface 110. 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 switch module 130, the power supply 140 is connected to a first terminal of the switch module 130, and a second terminal of the switch module 130 is connected to a power pin of the first communication interface 110.
The digital earphone 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 may be a universal serial bus Type C interface, i.e., a USB Type-C interface. Accordingly, the above second communication interface 210 may also be 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 (also referred to as a USB Type-C male plug). Correspondingly, the universal serial bus C-interface of the digital earphone 20 may be a universal serial bus C-socket, i.e., a USB Type-C socket (also referred to as a USB Type-C header). However, the present application is not limited thereto, and the usb C-type interface of the terminal device 10 may 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 may be matched to achieve connection.
It can be understood that the first communication interface 110 has 24 terminals, which can be plugged in forward or reverse, and has high transmission speed, no directivity, and can avoid misplug in use, thereby effectively reducing the failure rate. The d+ pin and the D-pin in the first communication interface 110 are pins for compatibility with the conventional 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 pin. The CC pins in the first communication interface 110 are channel configuration pins, which are the following second insertion identification pins. The other pins in the first communication interface 110 may be described with reference to the prior art, and the present application is not described in detail. The second communication interface 210 of the digital earphone 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 earphone 20 is grounded through a pull-down resistor, so that the terminal device 10 recognizes the digital earphone 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 of the digital earphone 20, the processor 120 controls the switch module 130 to be closed, and the power supply 140 is connected to the power pin of the first communication interface 110 to supply power to the digital earphone 20.
In this embodiment, the power source 140 is typically a battery, and the current power source 140 has a power voltage ranging from 3.2V to 4.45V, which is the battery voltage in the prior art.
As shown in fig. 1, the power supply voltage VBAT of the power supply 140 is output to the digital earphone 20 through the power supply pin VBUS of the first communication interface 110, that is, the terminal device 10 supplies the power supply voltage of 3.2V to 4.45V to the digital earphone 20 for supplying power. That is, it directly provides the power voltage of 3.2V-4.45V to the digital earphone 20 to supply power, avoiding the redundant electric quantity consumed by the digital earphone 20 during the working and standby, further reducing the power consumption of the digital earphone 20 during the working and standby, and improving the standby time of the digital earphone 20.
According to the embodiment, the electronic device assembly relates to a terminal device and a digital earphone, and since the terminal device comprises a power supply, a processor, a first communication interface and a switch module, the digital earphone comprises a second communication interface, and the processor controls the switch module to be closed when the first communication interface is connected with the second communication interface of the digital earphone, so that the power supply is conducted with a power supply pin of the first communication interface to supply power to the digital earphone. That is, the terminal device directly outputs the power supply voltage to the digital earphone to supply power under the condition of being connected with the digital earphone, which is equivalent to reducing the voltage supplied to the digital earphone, so that the power consumption of the digital earphone during operation and standby is reduced under the condition of not affecting the earphone function.
In one embodiment, as shown in fig. 2, the terminal device 10 further includes a boost module 150. A first input of the boost module 150 is connected to the power supply 140, a second input of the boost module 150 is connected to the processor 120, and an output of the boost module 150 is connected to a power pin of the first communication interface 110.
In this embodiment, when the first communication interface 110 is connected to an OTG device other than the digital earphone 20, the processor 110 controls the switch module 130 to be turned off, and controls the boost module 150 to be started to supply power to the OTG device.
It can be understood that after the terminal device 10 boosts the power supply voltage of 3.2V to 4.45V to 5V through the boost module 150, at this time, if the external device connected to the terminal device 10 is an OTG device other than the digital earphone 20, the terminal device 10 will supply the 5V voltage to the OTG device to supply power, so that normal operation of other OTG devices other than the digital earphone 20 can be ensured.
It will be appreciated 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. An input terminal of the detection module 160 is connected to the second insertion identification pin of the first communication interface 110, and an output terminal of the detection module 160 is connected to the third input terminal of the boost module 150.
The second insertion identification pin is the CC pin in the above universal serial bus type C interface.
Specifically, in the case where 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, and in the case where the detection module 160 detects that the external device is an OTG device, the processor 120 detects whether the OTG device is the digital earphone 20, so that the detection accuracy can be further improved.
In one embodiment, as shown in fig. 2, the terminal device 10 further includes a diode 170, and the diode 170 is connected between the second end of the switch module 130 and the power pin of the first communication interface 110.
Specifically, when the first communication interface 110 of the terminal device 10 is not connected to an external device, the processor 120 controls the switch module 130 to be turned off, and the boost module 150 is in a turned-off state, when the terminal device 10 is connected to the external device, the detection module 160 detects whether the external device is an OTG device, and when the detection module 160 detects that the external device is an OTG device, the processor 120 controls the boost module 150 to start to supply power to the OTG device, that is, boost the power supply voltage to 3.2V-4.45V to 5V and then supply power to the OTG device.
In the case that the processor 120 further detects the OTG device as the digital earphone 20, the processor 120 controls the switch module 130 to be turned on first, and then controls the boost module 150 to be turned off, so as to directly supply the power voltage of 3.2V-4.45V to the digital earphone 20 for power supply. Since the processor 120 turns off the boost module 150 after the switch module 130 is controlled to be turned on, in order to prevent the 5V voltage of the power pin VBUS of the first communication interface 110 from flowing backward to the power voltage VBAT, a diode 170 is introduced, i.e. the diode 170 plays a role in preventing the 5V voltage from flowing backward to the power voltage VBAT. Meanwhile, when the power voltage of 3.2V-4.45V is directly supplied to the digital earphone 20 to supply power, the risk of burning the switch module 130 during high-voltage charging can be reduced through the diode 170.
In one embodiment, as shown in FIG. 2, the boost module 150 includes: the power supply control circuit comprises a booster circuit 151 and a power supply control circuit 152, wherein the input end of the booster circuit 151 is connected with a power supply 140, the first input end of the power supply control circuit 152 is connected with the output end of the booster circuit 151, the second input end of the power supply control circuit 152 is connected with the processor 120, the output end of the power supply control circuit 152 is connected with a power supply pin of the first communication interface 110, and the third input end of the power supply control circuit 152 is connected with the output end of the detection module 160.
The above boost circuit 151 may be an inductor.
Specifically, when the first communication interface 110 of the terminal device 10 is not connected to an external device, the processor 120 controls the switch module 130 to be turned off, and the boost module 150 is in a turned-off state, when the terminal device 10 is connected to the external device, the detection module 160 detects whether the external device is an OTG device, and when the detection module 160 detects that the external device is an OTG device, the processor 120 controls the power control circuit 152 to start the boost circuit 151 to supply power to the OTG device, that is, boost the power supply voltage to 3.2V-4.45V to 5V and then supply power to the OTG device.
In the case that the processor 120 further detects the OTG device as the digital earphone 20, the processor 120 controls the switch module 130 to be turned on, and then controls the power control circuit 152 to turn off the boost circuit 151, so as to directly supply the power voltage of 3.2V to 4.45V to the digital earphone 20.
In one embodiment, the processor 120 obtains the supply voltage of the power supply 140 through the boost module 150 with the power supply 140 being in conduction with the power supply pin of the first communication interface 110 to power the digital earphone 20; the processor 120 controls the boost module 150 to start and controls the switch module 130 to turn off when the power voltage is lower than a preset voltage threshold.
In this embodiment, when the power supply 140 is connected to the power pin of the first communication interface 110 to supply power to the digital earphone 20, the processor 120 obtains the power supply voltage of the power supply 140 through the power supply control circuit 152; when the power supply voltage is lower than the preset voltage threshold, the processor 120 starts the boost circuit 151 through the power supply control circuit 152, and at the same time, the processor 120 controls the switch module 130 to be turned off, and at this time, the power supply 140 supplies power to the digital earphone 20 through the boost module 150.
In this embodiment, when the power supply 140 is connected to the power pin of the first communication interface 110 to supply power to the digital earphone 20, the path loss of the switch module 130 is very small and is usually negligible, but the diode 170 has a certain voltage drop when being connected due to its own characteristic, and the voltage drop is usually between 0.3V and 0.4V. In order to enable the digital earphone 20 to remain operational at low voltages, such as when the supply voltage VBAT is less than 3.6V.
In general, the processor 120 may obtain the power supply voltage of the power supply 140 through the power supply control circuit 152, for example, may obtain the power supply voltage of the power supply 140 in real time, or may periodically obtain the power supply voltage of the power supply 140, and if the power supply voltage is lower than a preset voltage threshold, for example, lower than 3.6V, the processor 120 may control the power supply control circuit 152 to start the boost circuit 151, and simultaneously control the switch module 130 to be turned off, so that the power supply 140 supplies power to the digital earphone 20 through the boost module 150.
According to the embodiment, under the condition that the power supply voltage is lower than the preset voltage value, the boosting module is controlled to restart so as to boost the power supply voltage and then supply power to the digital earphone, so that the normal operation of the digital earphone can be ensured.
The embodiment of the invention also provides terminal equipment which can be mobile phones, tablet computers, notebook computers, palm computers, wearable equipment and other equipment.

The processor 120 is connected to the first communication interface 110. 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 switch module 130, the power supply 140 is connected to a first terminal of the switch module 130, and a second terminal of the switch module 130 is connected to a power pin of the first communication interface 110.

In this embodiment, the power source 140 is typically a battery, and the power source voltage of the power source 140 is typically 3.2V-4.45V, which is the battery voltage.
As shown in fig. 1, the power supply voltage VBAT of the power supply 140 is output to the digital earphone 20 through the power supply pin VBUS of the first communication interface 110, that is, the terminal device 10 supplies the power supply voltage of 3.2V to 4.45V to the digital earphone 20 for supplying power. That is, it directly provides the power voltage of 3.2V-4.45V to the digital earphone 20 to supply power, avoiding the redundant electric quantity consumed by the digital earphone 20 during the working and standby, further reducing the power consumption of the digital earphone 20 during the working and standby, and improving the standby time of the digital earphone 20.
According to the embodiment, since the terminal device includes a power supply, a processor, a first communication interface and a switch module, when the first communication interface is connected with a second communication interface of the digital earphone, the processor controls the switch module to be closed, so that the power supply is conducted with a power pin of the first communication interface to supply power to the digital earphone. That is, the terminal device directly outputs the power supply voltage to the digital earphone to supply power under the condition of being connected with the digital earphone, which is equivalent to reducing the voltage supplied to the digital earphone, so that the power consumption of the digital earphone during operation and standby is reduced under the condition of not affecting the earphone function.
In one embodiment, as shown in fig. 2, the terminal device 10 further includes a boost module 150. A first input of the boost module 150 is connected to the power supply 140, a second input of the boost module 150 is connected to the processor 120, and an output of the boost module 150 is connected to a power pin of the first communication interface 110.
In this embodiment, when the first communication interface 110 is connected to an OTG device other than the digital earphone 20, the processor 110 controls the switch module 130 to be turned off, and controls the boost module 150 to be started to supply power to the OTG device.
It can be understood that after the terminal device 10 boosts the power supply voltage of 3.2V to 4.45V to 5V through the boost module 150, at this time, if the external device connected to the terminal device 10 is an OTG device other than the digital earphone 20, the terminal device 10 will provide the 5V voltage to the OTG device to supply power, so that normal operation of other OTG devices other than the digital earphone 20 can be ensured.
It will be appreciated 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. An input terminal of the detection module 160 is connected to the second insertion identification pin of the first communication interface 110, and an output terminal of the detection module 160 is connected to the third input terminal of the boost module 150.

Since the processor 120 controls the switch module 130 to close before closing, the boost module 150 is turned off, in order to prevent the 5V voltage of the power pin VBUS of the first communication interface 110 from flowing backward to the power voltage VBAT, the diode 170 is introduced, i.e. the diode 170 plays a role in preventing the 5V voltage from flowing backward to the power voltage VBAT.

In order to enable the digital earphone 20 to remain operational at low voltages, such as when the supply voltage VBAT is less than 3.6V.
In general, the processor 120 may obtain the power supply voltage of the power supply 140 through the power supply control circuit 152, for example, may obtain the power supply voltage of the power supply 140 in real time, or may periodically obtain the power supply voltage of the power supply 140, and if the power supply voltage is lower than a preset voltage threshold, for example, lower than 3.6V, the processor 120 may control the power supply control circuit 152 to start the boost circuit 151, and simultaneously control the switch module 130 to be turned off, so that the power supply 140 supplies power to the digital earphone 20 through the boost module 150.
According to the embodiment, under the condition that the power supply voltage is lower than the preset voltage value, the boosting module is controlled to restart so as to boost the power supply voltage and then supply power to the digital earphone, so that the normal operation of the digital earphone can be ensured.

S41, in the case that the detection module 160 identifies that the external device is an OTG device through polling detection, the processor 120 controls the switch module 130 to be turned off, and starts the boost circuit 151 through the power control circuit 152 to boost the power supply voltage from 3.2V to 4.45V to 5V, and then supply power to the external device, that is, the mobile terminal 10 enters the OTG 5V mode.
S42, the processor 120 further detects whether the OTG device is the standard digital earphone 20 (the working voltage of the standard digital earphone is typically 3.1V), and if the OTG device is the standard digital earphone 20, performs the following step S43, otherwise, performs the following step S45.
S43, the power supply control circuit 152 detects whether the power supply voltage is greater than 3.6V, and if so, performs the following step S44, whereas, performs the following step S45.
S44, the processor 120 controls the switch module to be closed (the VBAT channel is opened), and simultaneously, the booster circuit 151 is closed through the power supply control circuit 152, at this time, the power supply voltage of 3.2V-4.45V is directly supplied to the digital earphone 20 for power supply, and the process is ended.
S45, the mobile terminal 10 maintains the OTG 5V mode.
