Keyboard, terminal equipment and character input method

Abstract

The invention provides a keyboard, terminal equipment and a character input method. The keyboard comprises at least one key device, an energy storing device, a processor and a signal transmitter. Each key device corresponds to one power generating device. The power generating devices are used for converting mechanical energy generated when the corresponding key devices are pressed into electric energy and transmitting the electric energy to the energy storing device. The energy storing device is used for carrying out rectifying and voltage stabilizing on the received electric energy generated by the power generating devices and providing the electric energy with voltage stabilized for the processor. The processor is used for using the electric energy provided by the energy storing device for work, recognizing detection signals received when the key devices are pressed, determining at least one piece of key encoding information, and outputting character information corresponding to the key encoding information through the signal transmitter. The keyboard has an electricity self-generating function, electricity supply of the keyboard is effectively achieved, and then convenience and flexibility of using the keyboard are promoted.

Description

Technical field [0001] This application relates to the field of information processing technology, and in particular to a keyboard, a terminal device and a character input method. Background technique [0002] With the development of science and technology, there is a development trend that wearable devices replace smart terminal devices. This also means that the unique dial answering method of traditional smart devices is gradually no longer applicable with the miniaturization and wearability of smart devices. [0003] Specifically, one of the devices used by traditional smart devices to answer dialing is a keyboard. At present, there are many types of keyboards in the market, for example: from the perspective of keyboard working principles, including membrane keyboards, mechanical keyboards, electrostatic capacitive keyboards, etc.; from the perspective of obtaining power and transmitting information from the keyboard, including wired keyboards And wireless keyboard. Among the...

Problems solved by technology

[0005] However, wearable smart devices are limited in size, and the power supply equipment equipped with them can support the work of the wearable smart device for a limited time. If the keyboard needs to be powered additionally, it will cause the wearable smart device to work. The time is greatly shortened, which will reduce the convenience of wearable smart devices
