ABSTRACT:
The present invention relates to an electromechanical wind chime. The chime includes a disk from which a hammer assembly is suspended. Additionally, a plurality of tubular chimes are suspended from the disk and surround the hammer assembly. The hammer assembly houses an internal electric motor, and an associated eccentric rotor. The motor serves to move the assembly about a central axis. In this manner, the hammer assembly comes into contact with the chimes to produce a pleasing sound. A control unit is coupled to the hammer assembly by way of an electric cord. The control unit includes means to control the current being delivered to the electric motor. Through the control unit the current can be shut off after a predetermined amount of time has elapsed. Additionally, the unit can alternate the frequency with which the current is delivered to produce a more random motion. An embodiment employing a solenoid in place of an electric motor is also disclosed.
