At present,, need on existing mobile phone, to add DC generator though the self power generation mobile phone is arranged, device such as generating drivings grade, this self power generation handset structure complexity, cost is higher, charge efficiency is not high and waste time and energy.

Summary of the invention

The utility model is established Blast Furnace Top Gas Recovery Turbine Unit (TRT) for solving in the existing self power generation mobile phone, and complex structure, the technical problem that cost is high provide a kind of saves energy and cost low self power generation mobile phone.

For reaching above-mentioned technical purpose, the technical solution of the utility model is:

A kind of mobile phone, comprise first slide mass, can with second slide mass and the charging circuit of the first slide mass slide relative, the sliding path of first slide mass is provided with a kind of in magnet or the coil, and the another kind in magnet or the coil is set on described second slide mass; Described mobile phone also includes rectification circuit and filter regulator circuit, and the two ends of described coil link to each other with rectification circuit, connects by filter regulator circuit between described charging circuit and the rectification circuit.

Described rectification circuit is a single phase bridge type rectifier circu, is connected into bridge architecture mutually by four diodes.

Described filter regulator circuit comprises electric capacity and the voltage-stabiliser tube that is arranged in parallel between rectification circuit and charging circuit, and wherein said voltage-stabiliser tube is near charging circuit, and the plus earth of voltage-stabiliser tube.

Further, when first slide mass and second slide mass overlap, described magnet be positioned at coil directly over or under.When first slide mass and the second slide mass slide relative, significant change takes place in the magnetic field in the coil like this, thereby it is stronger to produce electric current, and charge efficiency is higher.

Further, described first slide mass or second slide mass have groove, just in time allow in a kind of card entry slot of magnet or coil.It is convenient so both to have slided, and has also guaranteed the compact conformation of mobile phone and attractive in appearance.

Further, described groove be shaped as square or circular.

Further, described magnet is selected stable performance for use, the alnico magnet that temperature coefficient is good.

Advantage of the present utility model: by existing slide phone is increased said structure, under the prerequisite that does not change the original design of mobile phone, ingenious utilization slip cutting magnetic induction line produces electric energy and gives cell-phone charging, prolonged the stand-by time of mobile phone, emergent charging for mobile phone plays great role, have simple in structurely, save electric energy and lower-cost advantage.
