Device for supplying electric energy for mobile phone

Abstract

The invention provides a device for supplying electric energy for a mobile phone. The device is characterized in that by means of a piezoelectric apparatus in the mobile phone and by pressing a piezoelectric button, the piezoelectric body converts the mechanical energy into electric energy; and then through an electric energy conversion device, as the electric energy is supplied to the mobile phone for charging, no other devices are required in the open air and the mobile phone can be directly charged so that people does not need carrying a charger and a standby battery when going out and also does not need carrying a plurality of batteries so as to save the trouble of changing batteries and bring convenience to people for going out; as the piezoelectric material is provided with very high energy density, the piezoelectric apparatus is small in volume and light in weight, and can be applied to electronic equipment and realize full conversion of energy; and the energy generated through working of external force by means of the piezoelectric effect is converted into electric energy, so that the traditional mode for charging for the battery of the mobile phone is changed and the device for supplying electric energy for a mobile phone is simple in structure and quick in giving a response, and has wide application field space.

Description

technical field [0001] The invention relates to a device for power supply, in particular to a device for providing electric energy for a mobile phone. Background technique [0002] Mobile phone is an essential device in people's daily life, but the battery in the mobile phone must be taken off to charge after it is exhausted. Often turning on and off has a certain impact on the service life of the mobile phone. When people are out on business or traveling, the battery is dead, and if they do not carry a spare battery, it will bring great inconvenience to people's lives. It's also a hassle to have cell phones cut off when people are on the phone. The time of some mobile devices will change after the battery is replaced, and the time needs to be readjusted. There are also inconveniences in using the direct charging method to charge mobile devices, such as not being able to take the mobile phone with you. [0003] When we use the mobile device, the energy touched by the mobi...
