A further object of the present invention is to provide a wrist exerciser which comprises a plurality of light emitting diodes arranged in an equally spaced manner around the rotor which emit light during the rotation of the rotor of which the light intensity is dependent upon the rotational speed of the rotor so as to serve as an indication of the rotational speed of the rotor.
A further object of the present invention is to provide a wrist exerciser wherein the rotor is provided with a central bore which is partitioned into separate chambers that generate sounds during the rotation of the rotor due to the air flow in/out of the chambers.
Yet a further object of the present invention is to provide a wrist exerciser which comprises an electrical generator comprised of a pair of coils of conductive wires rotatable in unison with the rotor and a magnet that is stationary with respect to the rotor so that the rotation of the rotor induces an electrical current in the coils to power the light generation device due to the coils' cutting through of the magnetic line of force of the magnet.
A further object of the present invention is to provide a wrist exerciser that comprises lighting elements which emit light having an intensity depending upon the rotational speed of the rotor so as to be more appealing to the general consumers.

With reference to the drawings and in particular to FIGS. 1, 2 and 3, wherein a wrist exerciser constructed in accordance with the present invention, generally designated with reference numeral 10, is shown, the wrist exerciser 10 comprises a spherical casing constituted by a lower member 11 and an upper member 60 both being substantially hemispherical and connected to each other to define a hollow spherical structure inside which a ring 30 is received and rotatable about a first axis of the sphere and a rotor 40 rotatably supported within the ring 30 and rotatable about a second axis of the sphere which is substantially normal to the first axis. A counter 20 is selectively provided and attached to a bottom opening 15 of the lower member 11 which is located substantially opposite to the upper casing member 60.

Such a conventional wrist exerciser has certain disadvantages. For example, the conventional wrist exerciser is not provided with a counter to show the turns that the user rotates the rotor. Further, such a conventional wrist exerciser provides only simple rotation of the rotor which may not be appealing enough to the general consumers. The reduction in the rotational speed of the rotor is also hard to know by the user.
