Hub with audio signal sharing

A hub with audio signal sharing comprising:

• a multi-function control unit;
• a microprocessor;
• at least one port connected to the multi-function control unit, which controls the at least one port to connect with a computing device;
• a universal serial bus (USB) audio control unit connected to the multi-function control unit;
• an audio processing module connected to the USB audio control unit and the microprocessor;
• a wireless module connected to the audio processing module and the microprocessor so as to be used for wireless communication with a mobile device;
• and
• an audio input and output module connected to the audio processing module and the microprocessor, and including an audio cable jack used for connecting with an audio input and output device, and/or a built-in speaker and a microphone,
• wherein the microprocessor controls the audio processing module to select and process audio signals among the computing device, the mobile device, and the audio input and output device, to enable these devices to conduct a multi-party call, so that each of these devices receives audio signals from other devices simultaneously and play the received audio signals simultaneously.
