Referring to fig. 1, some embodiments of the present application provide a multifunctional docking station that is compatible with speakers and a display. The docking station comprises a shell and a loudspeaker 11 fixed on the shell, wherein a circuit board is arranged in the shell, the docking station is provided with a main interface 12 for connecting an external host 200, a plurality of universal serial bus (Universal Serial Bus, USB) interfaces 13 and a high-definition multimedia interface (High Definition Multimedia Interface, HDMI) interface 14 connected with the main interface 12, a multiport transponder 15 (HUB), an audio processor 16, a digital-analog audio converter 17 and an audio power amplifier 18 connected with the loudspeaker 11 are sequentially arranged on the circuit board, and the USB interfaces 13 and the main interface 12 are connected with the multiport transponder 15. Through integrated audio amplifier function in the docking station for the docking station is as the accessory commonly used of computer equipment, has the convenience of being convenient for remove to and multiport conversion and charge-discharge function are individual, when putting up the meeting, also can be used as the audio amplifier, have saved originally required independent audio amplifier, make the construction of conference system simple, and the construction of single equipment also means the possibility greatly reduced that breaks down, also possesses the practicality of a tractor serves several purposes.

The docking station in these embodiments can expand USB devices connected to the external host 200 to transmit data, such as USB disk, keyboard, mouse, hard disk, and other devices conforming to USB specifications, by providing several USB interfaces 13, such as two or more. For example, the USB interface 13 is 3.0 or less, so as to meet the requirement of high-speed data transmission such as serial advanced technology attachment (SERIAL ADVANCED Technology Attachment, SATA)/Solid state drive (Solid STATE DISK or Solid STATE DRIVE, SSD) interface hard disk, and the highest supporting rate is 5Gbps.

The working principle of the implementation is that signals are transmitted to the multiport repeater 15 through the D-, D+ pins of the USB interface 13, the multiport repeater 15 transmits the signals to the external host 200, the external host 200 can be a computer or a mobile phone, and the external host 200 detects the received USB device information and judges the type of the USB device. And then the signal types required by the external host 200 are communicated for data information transmission and exchange. Also, a device that sends and receives signals through SSTX-, SSTX + pins of the USB interface 13, and if the multiport repeater 15 detects that both sending and receiving are possible, determines that the back end is connected to USB 3.0. And then performs high-speed data transmission and reception to the external host 200 through the bridging function of the multiport repeater 15.

The main interface 12 adopts a Type-C interface, is connected with a computer or a mobile phone through the Type-C interface, can simultaneously transmit audio and video data, and can also supply power to the docking station by utilizing the external host 200. In addition, if the power of the docking station is larger, when the external host 200 is insufficient to power the docking station through the main interface 12, or when the external host 200 also needs to power the docking station, referring to fig. 2, a power interface 19 may be further provided, and the external host 200 may be powered through the main interface 12, for example, the power interface 19 is also a Type-C interface, and even further adopts a Type-C Pulse Duration (PD) interface, a PD power source may be connected, for example, the docking station may be powered and the computer may be powered through the docking station, and in the case that the Type-C interface of the external host 200 is occupied for a long period, the computer may still be charged, so as to ensure that the computer can work for a long period.

In some embodiments, the main interface 12 employs a Type-C interface, on which a Type-C protocol chip and a PD3.0 controller, such as a VL103R chip, are disposed, and the VL103R chip includes a VBUS-managed power management unit for Type-C, and may detect that the Type-C external host 200 provides power supply when no PD power is input, and when detecting that a PD power is inserted, switch to a PD power supply mode, and transfer the PD power to the Type-C external host 200, so that the power supply mode is quickly switched.

When the Type-C interface external host 200 is used for providing power (no PD power supply), the power provided by the Type-C external host 200 is transmitted to an integrated power switch converter chip (such as an IM2605 chip) through VBUS, and the integrated power switch converter chip outputs stable 5V power to provide power for the docking station.

When the PD power supply is used, the integrated power supply switch converter chip sends out a signal to inform the VL103R chip, power supply information required by the VL103R chip to communicate with the Type-C external host 200 is transmitted back to the integrated power supply switch converter chip, PD power supply externally connected to the integrated power supply switch converter chip is transmitted to the integrated power supply switch converter chip, and the integrated power supply switch converter chip outputs stable 5V power supply to supply power to the docking station. And the PD power supply is transmitted to TYPE-C host equipment (such as a computer or a mobile phone) by the integrated power supply switch converter chip to charge the equipment.

In one embodiment, the multiport repeater 15 is communicatively coupled to the audio processor 16 via a USB 2.0 channel to conserve the USB interface 13 resources at higher transmission speeds.

Referring to fig. 3, in one embodiment, a switch 21 is connected between the audio processor 16 and the multiport repeater 15, and the switch 21 is used to switch between transmitting the audio signal accessed by the main interface 12 from the multiport repeater 15 to the audio processor 16 and transmitting the audio signal output from the microphone 20 from the audio processor 16 to the multiport repeater 15. In this manner, the use of the switch 21 may save I/O port resources of the multiport repeater 15. In other embodiments, the switch 21 may not be used, and the multiport repeater 15 may transmit audio signals using two different channels.

In one embodiment, the multiport repeater 15 includes a hub chip VL817, the audio processor 16 includes an audio processing chip XVF3000, the digital-to-analog audio converter 17 includes a digital-to-analog audio conversion chip HT5010, the audio processing chip XVF3000 converts the received audio signal into an I ² S digital audio signal that is transmitted to the digital-to-analog audio conversion chip HT5010 through an I ² S channel pin, the audio power amplifier 18 includes an audio power amplifying chip HT6872, and the HDMI interface 14 is communicatively connected to the main interface 12 through a video conversion chip.

The docking station working power supply can be automatically switched by the PD interface or the Type-C interface. The PD interface is configured to ensure a normal supply current for charging and to charge the external host 200. The principle of PD charging is that when a PD adapter is plugged in, the PD adapter transmits a power supply capability information to the corresponding power demand external host 200, and after the external host 200 receives the power supply capability information, the PD adapter transmits a power demand information to the PD adapter, and the PD adapter adjusts the voltage and current to supply power.
