Abstract

An electronic device comprises input equipment and an auxiliary battery, wherein the auxiliary battery comprises an input layer and a piezoelectric layer below the input layer, wherein the piezoelectric layer is connected to the auxiliary battery; the piezoelectric layer deforms to generate electric current owing to input operation of the input layer so as to charge the auxiliary battery. The invention provides a power supply method of the electronic device.

Description

technical field [0001] The invention relates to an electronic device and a power supply method thereof, in particular to an electronic device with power generation function and a power supply method thereof. Background technique [0002] In order to save energy and meet the requirements of green environmental protection, the lower the energy consumption of electronic devices, the better. Electronic devices are usually equipped with input devices such as keyboards and touch screens. Users will perform corresponding actions when using these input devices to input. Kinetic energy is generated, so the industry has the idea of ​​converting these kinetic energies into electric energy. For example, Chinese patent application No. 200810246005.7 discloses a keyboard power generation device, which generates electricity by tapping the keyboard. Airbags are arranged under the keys of the keyboard. When the button is pressed, the airbag is compressed and deformed to drive the motion indu...
