1 to Fig. 3, and wherein vibratile mass is suitable for resonating with amplitude of oscillation with natural frequency.Electromechanical assembly 222 has electric output, and electric output comprises two lead-out terminals 226,228 in this embodiment, and each lead-out terminal is connected with corresponding electrical lead 230,232.In use, electrical lead 230,232 is connected to through corresponding connector 234,236 and treats by electromechanical generator 220 electrically driven (operated) external circuits. More preferably, said voltage regulator comprises at least one Zener diode. Compare with first execution mode, second execution mode is improved from dc voltage and electric current after the rectification of the AC/DC rectifier that links to each other with the electric output (being the lead-out terminal of coil in this embodiment) of electromechanical assembly 2 through detecting.Therefore, in second execution mode, electromechanical generator 120 comprises as above with reference to the described electromechanical assembly 2 that is used for mechanical vibrational energy is converted into electric energy of Fig.

In Fig. 1, damper 14 is schematically shown the structure into piston and cylinder in order to simplify.Yet as well known to those skilled in the art, damper 14 comprises the assembly that can when its two parts relative motions, produce electric current.Mechanical energy can be converted into electric energy through electromagnetic coupled and/or piezoelectricity coupling.Usually, but ” piston ” that be arranged to translational motion comprises electric coil, is arranged to static ” cylinder ” and comprises the magnet assembly that produces electric coil flux areas disposed therein.Yet, opposite structure capable of using.The motion of electric coil in magnetic flux makes and in electric coil, generates electric current that this electric current can be used as the electric power source that drives the external device (ED) (not shown). The present invention also aims to provide a kind of improved electromechanical generator that is used for mechanical vibrational energy is converted into electric energy, and it is suitable for when amplitude exceeds certain threshold value, reducing the amplitude of resonator.
More preferably, when amplitude of oscillation is not more than predetermined maximum threshold the impedance of said shunt impedance element higher, and the impedance of said shunt impedance element is lower when amplitude of oscillation is higher than predetermined maximum threshold. The puncture voltage of each voltage regulator 238,240 is predefined for the short circuit that the output of the electricity of electromechanical generator 220 is provided when the output voltage of two lead-out terminals 226,228 surpasses the specific threshold corresponding with puncture voltage, puncture voltage is corresponding to the predetermined peak swing of oscillating mass body. Under open circuit conditions, promptly lack under the situation of the voltage regulator of this aspect according to the present invention, when sinusoidal drive acceleration increased, amplitude increased with linear mode accordingly.This means that amplitude can become greatly, makes at 250mg RMSSinusoidal drive acceleration under, the amplitude of mass motion is up to ± 1.8mm.This can cause damaging electromechanical generator.And output voltage can increase to high value accordingly, and this possibly make electromechanical generator when being used for existing the environment of potential explosion hazard (for example because fine powder or burning gases), constitute potential hazard.

When electromechanical generator when from the field of vibrating body harvest energy, coming into operation, can not be from all above variablees of the actual conditions that run into prediction.The amplitude of spring-mass body maybe be in time to change at intermittence and uncertain mode. Another benefit of utilizing voltage regulator to reduce this method of amplitude is to have limited output voltage.Exist under the environment of potential explosion hazard owing to fine powder or burning gases, output voltage and electric current must be by strict restrictions.All circuit of Fig. In another embodiment, said electromechanical generator also comprises the rectifier that is used for the electricity output rectification of electromechanical assembly, and said detector is suitable for detecting direct current and the direct voltage from this rectifier output.
