The prototype includes the body, nonmagnetic channel with coils on its surface and a magnetic bead that is placed in the channel. When you swing the device in the plane passing along the axis of the channel, the ball rolls and coils induced current, which is collected by the electronic circuit, and can be used if necessary.

The disadvantages of the prototype are

- depolarise ball, which causes the uncertainty of the magnetic flux when rolling the ball along the channel and, as a consequence, reducing the efficiency of the device.

- straightness of the channel requires its horizontal location otherwise, even with a slight tilt, the ball rolled into the end of the tube.

The invention solves the technical problem of obtaining a uniform signal is and moving the magnetic bead along the canal with coils, with simultaneous reduction of the requirements for the horizontal position of the channel.

The problem is solved in that the microgenerator includes the channel of a nonmagnetic material with coils of electric wire around it, end baffles and a magnetic ball inside the channel, and the magnetic ball includes a number of permanent magnets, having the form of truncated pyramids or cones (e.g., six), the joint opposite poles of a common magnetic core in the center of the ball, and the non-magnetic pipe has a bend the ends up.

The invention is illustrated in figures 1 to 4, where figure 1 shows the design of a microgenerator, figure 2 - schematic of the magnetic bead. Figure 3 and figure 4 show examples of embedding micro-generation in stand-alone power source where 1 - body, 2 - microgenerator, 3 - e-block, 4 - output adapter (figure 3) and cell phone (figure 4).

The microgenerator contains the channel in the form of curved ends up nonmagnetic tube 1, capped at both ends of the elastic support 2. The tube is placed coils (coil) electric wire 3.

Inside the tube is a ball 4 of non-magnetic matrix with multiple magnets 5, which are made in the form of (e.g. six) of truncated cones or pyramids, the narrow ends of which are connected by the magnetic circuit 6. Eriksberg covered with non-magnetic shell 7.

Powered microgenerator as follows. When the rocking device is rolling the ball along the channel, in which the magnetic lines of force from the total magnetic field of all the pyramids cross the winding coils and Indochinese current which is taken from output terminals received in the scheme and charge of the booster battery. The scheme of processing of the captured voltage is normal and is not the subject of this application.

This microgenerator can be embedded in any low-voltage device (such as a cellular or satellite telephone, a charging device, not connected to the electrical grid, low-power transmitter), which during operation are subject to natural fluctuations, such as: walking, running, riding in vehicles, swimming, etc.

The presence polymannose ball and bending channel provides greater sensitivity of the device to its fluctuations, and therefore higher efficiency.

Thus, the expected of the invention, the technical result is confirmed.
