Keyboard with inductive switching

This author is about a keyboard with inductive switching function, especially a keyboard that switches the output signal mode through the sensing module.

The keyboard plays an extremely important role in the communication between people and technology. Most computers or other digital devices can use the keyboard as a communication interface, and the application of the keyboard has different connection methods with the advancement of technology.

The connection between the keyboard and the computer was developed from the original RS-232/DB-9 communication interface standard to the PS/2 communication interface, and finally developed to the most compatible USB communication interface, and the connection method is Wired connection is the main method. However, as the application of computers and digital devices gradually integrates into personalization and daily life, the application environment is no longer limited to desks or computer desks. Naturally, between keyboards and computers or digital devices. The connection method also slowly derives the need for wireless connection and wide range connection distance within a limited distance limited by the wired connection method.

In order to achieve the wireless connection technology required for wireless keyboards, wireless connection technologies such as infrared rays and Bluetooth have been gradually developed. Among them, infrared technology is used in practical applications due to directional limitations and signals being easily obscured by obstacles, etc. The restriction is too narrow, so it is gradually replaced by the newer Bluetooth technology. The Bluetooth wireless technology uses 2.4GHz wireless channels to transmit and receive signals, without electromagnetic interference, and can achieve one-to-one or one-to-many device wireless. Connected, the keyboard with Bluetooth technology can be used up to 10 meters As far as the digital devices compatible with Bluetooth keyboards, such as computers, tablets, smart phones, etc., can be used universally, it also brings great convenience.

Although Bluetooth technology has been widely used, the external device that accepts keyboard signals in some usage scenarios does not support Bluetooth technology. For example, before the computer has entered the operating system to start the driver, or Compared with the original booting system, such as the BIOS booting program and the traditional DOS operating system, Bluetooth cannot be used, which makes the Bluetooth keyboard use blind spots. Therefore, there is a need to set the BIOS screen and the traditional DOS system. Users, or have the need to connect with other digital devices that are not compatible with Bluetooth technology, have developed a keyboard with a wireless connection interface and a wired connection interface, which makes the keyboard adapt to various operating environments and greatly enhances convenience.

However, such a keyboard having both a wireless connection interface and a wired connection interface has a drawback in that it is generally used to switch between a plurality of physical button combinations by switching various output modes to connect different external devices. It is complicated and inconvenient to use, and often forces the user to press the physical buttons with both hands, which greatly reduces the user experience.

In view of this, how to improve the keyboard switching method with the wireless connection interface and the wired connection interface to improve the various defects of the prior art is the problem to be solved by the creative.

In view of the problems of the prior art, one of the aims of the present invention is to provide a keyboard with an inductive switching function, which can switch between wired and wireless modes among multiple devices in various ways.

In order to achieve the above purpose, the keyboard of the creation with inductive switching function includes A button module, a micro control unit and a plurality of output ports, wherein the button module has a plurality of buttons for the user to input a keyboard signal, the micro control unit and the button module and the display module are electrically Connected, and used to receive a switching signal to determine the output authority of each output port and to distribute the keyboard signal, each of the output signals respectively transmitting the keyboard signal in a wired or wireless manner, wherein the The inductive switching function keyboard has a sensing module and a display module, the sensing module has a plurality of optical sensors and is used for sensing light changes to generate the switching signal, the display module has a plurality of indicator lights, and The number of the indicator lights is equal to the number of the output ports, and each of the indicator lights is switched according to each of the output modes, so as to provide the user with an at-a-glance information to know the current output mode; wherein each output port has output rights. The keyboard signal will be output from each of the output ports to an external device.

Each of the output ports may be a wired USB transmission interface or may be a wireless Bluetooth transmission interface, and the output ports may be a combination of the wired USB transmission interface and the plurality of wireless Bluetooth transmission interfaces, and in another implementation In the aspect, the keyboard with the inductive switching function further has a voice recognition module, which is used to detect the voice command of the user, and correspondingly outputs the switching signal to determine which output port has the output authority and The keyboard signal is outputted from the specific output to the external device; and the sensing module and the voice recognition module can be disposed on the keyboard with the inductive switching function, and the inductive switching function can be externally Outside the keyboard.

By taking the above methods, the creation of the function of wired and wireless output has the advantages of intuitive, diversified, and easy to operate, greatly increasing the versatility of the keyboard and greatly improving the shortcomings of the technology.
