C. adding a power-converting device in cell phone apparatus, the electric energy that piezoelectric produces is adjusted and converts by this device；
D. again the electric current through described power-converting device adjustment and conversion is stored in battery of mobile phone.
Preferably, when the electric energy produced by described TRT is converted by the described power-converting device in described step c, the charging voltage of battery of mobile phone is controlled.
Preferably, when the electric energy produced by described piezoelectric generating device is converted by the described power-converting device in described step c, also the electric current of battery of mobile phone is controlled.
Preferably, the conversion of electric energy is comprised the steps: by described power inverter
1) transformation process: the alternating current by producing by power generation device is carried out voltage transformation by a transformator；
2) rectification, filtering: the alternating current produced is passed through commutator and filter, makes alternating current be changed into unidirectional current；
3) direct current voltage reulation transformation process: by commutator and filter, alternating current will be made to change the unidirectional current produced by DC voltage regulation device, carry out voltage and current conversion, become charging voltage and charging current that mobile phone shell accepts.
The invention have the benefit that. provide new energy source for cell phone apparatus, the cell phone apparatus touch screen not in the past being used is reclaimed at the extruding energy of pressing cell phone apparatus and utilized, and this increases stand-by time for cell phone apparatus and has significant realistic meaning；Sustainable for cell phone apparatus provide electric energy, save the trouble changing battery to a certain extent；Do not need when people go on a journey to carry charger, reserve battery, go on a journey offer conveniently for people；Owing to piezoelectric has significantly high energy density, therefore the volume of piezo-electric device is little, lightweight, it is possible to obtains application in cell phone apparatus, and can achieve making full use of of energy, changes the traditional mode of cell phone apparatus battery charging；Owing to piezo-electric generating belongs to medium power generation mode, compared with traditional electrical power generators mode, having simple in construction, response is rapidly, it is possible to is suitable for the multiple driven by power mode such as DC driven, alternation power drive, has wide application space.
Detailed description of the invention
Details are as follows for the preferred embodiments of the present invention:
The present invention utilizes the method that the touch screen generating containing piezoelectric is powered for cell phone apparatus to be placed in inside cell phone apparatus by piezoelectric generating device, reclaim the produced energy of external force acting acting on cell phone apparatus, being stored as electric energy and supply cell phone apparatus to utilize, the method comprises the following steps:
A piezoelectric generating device is added inside cell phone apparatus, for the Absorption external force produced energy of acting on cell phone apparatus, piezoelectric generating device is using piezoelectric as working media, by piezoelectric effect, produced for external force acting energy is changed into electric energy, create the alternating current that waveform is complicated；
