Abstract

The invention discloses a magnetoelectric and piezoelectric combined generator. The magnetoelectric and piezoelectric combined generator comprises piezoelectric ceramic pieces, a base plate made of a constant elasticity material and a micro magnetoelectric generator capable of receiving vibration energy in the vertical direction, wherein double faces of the base plate are adhered with the piezoelectric ceramic pieces; one end of the base plate is fixed on a substrate, and the micro magnetoelectric generator is mounted at the other end of the substrate; and a micro magnetoelectric and piezoelectric combined generator body with a cantilever beam structure is formed by the micro magnetoelectric generator, the piezoelectric ceramic pieces and the base plate. According to the magnetoelectric and piezoelectric combined generator, the micro magnetoelectric generator is used as a piezoelectric generator spring oscillator so as to form a combined generator. Moreover, the natural vibration frequency of the piezoelectric spring oscillator is equal to the natural frequency of the magnetoelectric generator, so that the magnetoelectric generator generates electricity under a resonant state all the time so as to achieve high efficiency of magnetoelectric and piezoelectric combined generation. The outer diameter of the micro magnetoelectric generator is approximate to or equal to the width of the base plate of the piezoelectric ceramic pieces, so that the installation space is saved.

Description

technical field [0001] The invention belongs to the field of green energy development and application, and also belongs to the fields of micro-magnetoelectric generators and micro-piezoelectric generators, and relates to a magneto-voltage-electric combination generator. Background technique [0002] Piezoelectric generators rely on the deformation of piezoelectric ceramics to generate electrical energy. The greater the deformation of the ceramics, the greater the output current. The greater the displacement of the inertial body of the magnetoelectric generator is, the more the coil cuts the magnetic lines of force, that is, the greater the output current. The maximum displacement of the inertial body can only be obtained when the elastic system inside the magnetoelectric generator is in a state of resonance. Therefore lack a kind of power generation device that can combine two kinds of principles now, increase the device of overall power generation. Contents of the invent...
