Abstract: An alert system allows a dog to ring chimes that has been specially made for dogs, although the alert system can be used for other household pets as well. A beautiful sound resonates throughout the home to inform individuals that the dog needs to go out. The alert system may include a plurality of chimes arranged on a base that is either attached to a door hinge pin or mounted on a wall. Unlike conventional wind chimes, the dog door chimes does not include a wind catcher to cause the chimes to ring. Instead, the chimes are configured to sound when nudged by a dog's paw, body, head or nose, for example. The dog door chimes may include a relatively large ringer to prevent chewing thereupon by dogs.

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.

Abstract: A whistle is provided which will create two frequencies when blown to produce a beat. The whistle has a mouthpiece defining an inlet opening and an inlet passageway extending axially from the inlet opening to a main body which has two similar chambers extending generally axially. Air from the passageway engages two splitter edges associated one with each of the chambers. A lanyard receiver extends axially from the main body remote from the mouthpiece and defines a transverse cavity connected to one of the axial chambers. The whistle is made from first and second parts having mating peripheral surfaces where a joint is made. The arrangement of the whistle is such that two resonant frequencies are created each having a different audible frequency to create a beat. This is achieved in a simple, light and compact structure which is simple to assemble resulting in a relatively inexpensive whistle having good sound characteristics.

Abstract: A windchime that generates musical tones in response to very low wind speeds includes chime members that are grouped in pairs. The chime members of each pair of chime members include a massive chime member and a less massive chime member that are closely spaced apart from one another. In very low winds, the less massive chime members begin swinging and impinge against their adjacent more massive chime members. Thus, a musical tone is produced even before the more massive chime members begin swinging. This arrangement of parts reduces the sensitivity threshold of the windchime so that it performs its intended function in breezes moving at less than one-half a mile per hour. In a preferred embodiment, three sets of chimes are suspended from a tripod-like mounting member that includes aesthetically pleasing support legs.

Abstract: A light powered chime for indoor use specifically designed to be random, approximating a windchime. In one embodiment a solar cell provides current to a timing circuit and to a storage capacitor. The timing circuit intermittently fires a silicon controlled rectifier causing current to flow from the capacitor through a motor. A striker is connected to the motor shaft by way of a string and clip. Rotation of the motor causes the striker to contact one or more suspended chimes. Randomness is achieved by virtue of sunlight variability and by the mechanical and electrical design.

Abstract: An electromechanical chaotic chiming mechanism, analogous to the classical wind or water powered chime, includes a body or framework suspending a series of chimes with a pendulum suspended centrally among the chimes. A drive mechanism for the pendulum includes a permanent magnet on the pendulum and a drive electromagnet in a base positioned just below a centered rest position of the pendulum. With the electromagnet switched on and off, in a regular linear pattern, the electromagnetic drive causes a chime hammer on the pendulum to behave in a chaotic manner, sounding the chimes in a fashion virtually indistinguishable from natural meteorological forces acting on conventional windchimes. Variations can be made to the pattern or period of the drive electromagnet to vary the pattern of sound produced by the chimes.

Abstract: A whistle having two chambers of different size so that each is capable of generating a sound different to that generated by the other. Each chamber is elongate and has an open mouth located at the same end of the whistle body. A mouthpiece extends angularly from that end of the body and has two open-ended passages extending therethrough, each of which has an open inner end located adjacent a respective one of the chamber mouths. The two passages are located in close side by side relationship and are arranged so that a stream of air emerging from their respective inner ends passes across a respective one of the two chamber mouths so that the two chambers generate sound simultaneously. The two chambers generate relatively high and low frequency sound respectively.
