Description
Technical field
The utility model relates to digital interface adapters more particularly to a kind of list USB-C interface to switch to USB-C charging interface
And the adapter of earphone interface.
Background technique
Currently, the digital products such as many mobile phones, plate all eliminate the simulation earphone interface of 3.5mm on the market, only retain
Unique physical interface that one USB-C interface is connect as equipment with the external world.User states mobile phone or plate in use
When equipment, while listening to the audio content of equipment using USB-C interface, also needed sometimes using the USB-C interface
To equipment charge.But because only one USB-C interface of the equipment, causes user not can be implemented simultaneously above functions.
There is a kind of simulation turn that a USB-C is turned to USB-C and 3.5mm earphone interface on the market at present
Device is connect, but the program is primarily present following two aspects disadvantage: 1, compatibility issue.This analog switching device can only receive simulation
Audio, but many mobile phones and plate do not support USB-C interface to export analog audio signal, so analog switching device can not be simultaneous
Hold such equipment.2, charging rate is slow.Analog switching device maximum can only support the charging rate of 5V 500mA (2.5W).Charge bulk
Difference is tested, the demand of some users for wishing mobile phone quick charge is unable to satisfy.
Therefore, the adapter that a kind of list USB-C interface switchs to USB-C charging interface and earphone interface is researched and developed, ability is become
Field technique personnel's urgent problem to be solved.
Utility model content
The utility model be in order to solve above-mentioned deficiency, provide a kind of list USB-C interface switch to USB-C charging interface and
The adapter of earphone interface.
The above-mentioned purpose of the utility model is realized by technical solution below: a kind of list USB-C interface switchs to USB-
The adapter of C charging interface and earphone interface, including PCB motherboard, PCB motherboard side are connected with USB-C 1# interface,
The PCB motherboard other side is equipped with USB-C 2# interface and 3.5mm earphone interface, and the PCB motherboard is equipped with PD control chip and volume
Decoder, the USB-C 1# interface by PD control chip and codec respectively with USB-C 2# interface and 3.5MM earphone
Interface connection.
Further, the USB-C 1# interface is connected to motherboard by electric wire, or is directly welded on motherboard.
Further, the USB-C 1# interface is USB-C male connector or USB-C base.
Further, the PD control chip uses USB-PD agreement, and is connected to USB-C 1# and USB-C 2# interface
Equipment shake hands；The codec is shaken hands with the equipment for being connected to USB-C 1# and 3.5mm earphone interface.It shakes hands
After success, the electric energy for the charger for being connected to USB-C 2# interface, charged by USB-C 1# interface to mobile phone or plate；
Audio signal on mobile phone or plate is sent out from USB-C 1# interface, is played by 3.5mm earphone interface to earphone.
User can connect charger by USB-C 2# interface, and 3.5mm earphone interface connects earphone, then USB-C #1
Interface is connected on computer or plate.
The utility model compared with prior art the advantages of be:
1. faster charging rate.The built-in USB-PD of motherboard controls chip, is responsible for the USB-C #2 interface of charging, supports
USB-PD fast charge function, highest support the charging rate of 20V 3A (60W).
2. better suitability, plate of the present invention in addition to that can support android system, can also support windows system
The plate and laptop of system and IOS system.
3. volume is light and handy, easy to carry.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of list USB-C interface switchs to the adapter of USB-C charging interface and earphone interface, including PCB
Motherboard, PCB motherboard side are connected with USB-C 1# interface, and the PCB motherboard other side is equipped with USB-C 2# interface and 3.5mm ear
Machine interface, the PCB motherboard are equipped with PD control chip and codec, the USB-C 1# interface by PD control chip and
Codec is connect with USB-C 2# interface and 3.5MM earphone interface respectively.
Further, the USB-C 1# interface is connected to motherboard by electric wire, or is directly welded on motherboard.
Further, the USB-C 1# interface is USB-C male connector or USB-C base.
Further, the PD control chip uses USB-PD agreement, and is connected to USB-C 1# and USB-C 2# interface
Equipment shake hands；The codec is shaken hands with the equipment for being connected to USB-C 1# and 3.5mm earphone interface.It shakes hands
After success, the electric energy for the charger for being connected to USB-C 2# interface, charged by USB-C 1# interface to mobile phone or plate；
Audio signal on mobile phone or plate is sent out from USB-C 1# interface, is played by 3.5mm earphone interface to earphone.
User can connect charger by USB-C 2# interface, and 3.5mm earphone interface connects earphone, then USB-C #1
Interface is connected on computer or plate.
