That is,
A power generator is characterized in that one end of a coil spring 3 in which a magnet 2 is suspended and one end of a cylindrical coil 1 are attached to a top plate 4 constituting a housing. In the embodiment of FIG. 1, an example is shown in which three sets of power generating devices each including a cylindrical coil 1 and a bar-shaped magnet 2 are provided.

The rod-shaped magnet 2 is suspended by a tension coil spring 3 on the inner surface side of the cylindrical coil 1 so as to vibrate or swing. That is, it vibrates or swings up, down, left, and right in the tubular coil 1 to generate electric current in the tubular coil 1 to generate power. Vibration or rocking of the bar-shaped magnet 2 is performed by vibrating (rocking), tilting, or carrying a case (not shown) in any direction of up, down, left, and right. Of course, even when the power generation device 100 is mounted on the vehicle, the rod-shaped magnet 2 vibrates or swings to generate power due to the unevenness of the road in the process of starting, stopping, and traveling the vehicle. Further, when the power generation device 100 is attached to a tree or the like, power is generated in response to rocking of the tree due to wind power. Furthermore, when a housing (housing) floats on the sea, power is generated by waves.

Next, an example of the tubular coil 1 constituting the power generator 100 of the present invention will be described. The cylindrical coil may have any configuration such as a fusion coil or a coil wound around the outer periphery of a bobbin.

The fusion coil winds a fusible insulated conductor,
It is stuck. The fusible insulated wire is a double-structured covered wire in which a fusible film such as a thermoplastic resin or a thermosetting resin is baked on a covered wire such as polyurethane or polyester. The conductors can be bonded to each other by means of a solvent, electric heating, hot air heating, or the like, and the fusion coil can be integrally formed into a flat plate shape, a spherical shape, a cylindrical surface shape, or the like, and the bending strength can be obtained. Examples of the conductor used for the insulative insulated conductor include a round conductor having a circular cross section, a rectangular ribbon conductor, and a multi-parallel conductor obtained by processing a plurality of circular conductors in parallel.
The use of a ribbon conductor, a multi-parallel conductor, or the like allows a smaller space between the conductors, a denser arrangement, a smaller size, and a lower resistance than a round conductor.

Needless to say, the outer periphery of the tubular fusion coil 2 may be an arbitrary shape such as a square, a polygon, etc., in addition to the cylindrical shape. Also,
FIG. 5 shows an example in which only one coil is wound, but it goes without saying that the coil may be wound in a multilayer. Further, it is the same that a general contact coil spring may be used instead of the fusion coil. In this case, the coil spring itself may vibrate or rock in response to the vibration or rocking of the housing.

The magnetic member constituting the bar-shaped magnet 2 may be any member. For example, a resin magnet in which a magnetic powder is blended and molded into a synthetic resin binder, or Mn-A

In addition, in order to protect the coil and magnet from friction,
Coated with resin members such as epoxy resin.

The tension coil spring 3 for suspending the magnet may be formed by winding an arbitrary member such as a piano wire for spring, stainless steel, phosphor bronze wire, or the like. The means for attaching to the housing is also arbitrary such as adhesion, screwing, hooking, and the like. The same applies to the means for attaching the cylindrical coil 1 to the housing.
