Abstract

An apparatus for converting vibratory motion along a predetermined vibration axis to electrical energy comprises an enclosure having first and second opposite walls substantially parallel to one another.
A magnet carrier structure in the enclosure also has first and second opposite walls substantially parallel to one another. A pair of springs suspend the carrier structure in the enclosure so that corresponding first walls and corresponding second walls, respectively, face one another with a predetermined spacing therebetween. The springs allow reciprocating movement of the carrier structure relative to the enclosure only along the vibration axis in response to the vibratory motion. Separate magnet sets, each comprising a row of permanent magnets, are attached to a respective outer surface of the first and second walls of the carrier structure for producing a respective magnet flux.
Separate coil assembly sets, substantially configured and dimensioned like the magnet rows, are attached to a respective inner surface of the first and second walls of the enclosure and are situated to be magnetically coupled to a corresponding one of the separate magnet sets in order to produce electrical current due to magnetic flux changes whenever the carrier structure and the enclosure move reciprocally with respect to one another along the vibration axis.
