Abstract
A miniature generator includes a carrier having a tubular shaft on the inside, a substantially C-shaped permanent magnet mounted on the tubular shaft inside the carrier, a match mounted on the tubular shaft inside the carrier and joined to the permanent magnet to keep the permanent magnet in a slightly unbalanced condition for allowing rotation of the permanent magnet upon movement of the carrier by an external force, and a winding holder sleeved onto the carrier and having wound thereon multiple windings for inducing an induction current upon rotation of the permanent magnet in the carrier.
