Description

Composite electronic device

technical field

The present invention relates to a composite electronic device, in particular to an electronic device that can integrate different electronic units and communicate with a host through a single USB 3.0 connector.

Background technique

USB (Universal Serial Bus), commonly known as Universal Serial Bus, is designed to solve the problem of independent connection of interface devices and ease of use. USB can support plug-and-play in use. If the operating system has already installed the device driver, the device with USB can be installed or removed directly while the operating system is running, which greatly increases the convenience of use.

USB 3.0 is the third major revision of the USB standard, and it has been renamed USB 3.1 Gen 1 by the USB Implementers Forum (USB-IF). USB 3.1 Gen 1 (USB 3.0) has a plug-and-play function, and can support both USB3.0 (SuperSpeed USB) and USB2.0 (High Speed USB). The former can increase the signal bandwidth to 5Gbp/s, while the latter can Increase the signal bandwidth to 480Mbps.

Most of the current electronic devices can support USB3.0, such as USB flash drives, USB Bluetooth receivers or USB wireless network cards, which can be inserted into the USB slot of the host computer through the USB connector to make the electronic device To communicate with the host computer signal. When the electronic device and the host computer can support USB3.0 at the same time, the two can communicate with the signal bandwidth of USB3.0, but if one of them only supports USB2.0, the two will not After the signal communication at the physical layer, the speed is automatically reduced to the signal bandwidth of USB2.0 for communication.

With the change of user habits, portable electronic devices such as notebook computers and tablets have become smaller and lighter, and under this trend, the number of USB slots on portable electronic devices has also been relatively reduced Once the user wants to add a peripheral electronic device with a USB connector to the portable electronic device, the USB device that has been plugged into the portable electronic device must be pulled out first, and then inserted into the peripheral electronic device. can be solved. However, this method of repeatedly removing and adding peripheral electronic devices will cause great inconvenience to users.
