Description
The present invention relates to an instrument or device for obtaining melodious and harmonious sounds, such as resembling the sounds of tropical birds and animals. This instrument for producing pleasant and harmonious sounds is useful as an educational device for imitating the sounds of small birds of different countries, as well as small nighttime insects or animals, such as the little frog, or "coqui"of Puerto Rico.
This device is advantageous in the instruction in science and biology courses, such as physics and ornithology, since the sounds of melodious birds, for example, can be reproduced in the classrooms without the necessity of field study out-of-doors. In this regard, students of ornithology may be introduced to and become familiar with the sounds of tropical birds, for example, while in the laboratory or classroom. Such melodious and harmonious bird and animal sounds produced by the present instrument also enable simulation of many sounds that may be useful in the production of background sound tracks in movies and sound cassettes. Furthermore, the structure of the present invention provides an interesting toy which is entertaining for children by enabling them to reproduce various sounds.
The melody bird instrument of the present invention achieves these desirable features by means of a construction having a central air chamber with a longitudinal aperture for the entry of air and a small aperture at one end of the air chamber through which the air exits into a hollow base conical member having an open base portion. This assembly further includes a front conical section attached to the end of the air chamber opposite the base conical section. A holding member, such as a string, is attached at the front conical section for operation of the device. In this regard, the device is rotated about its longitudinal axis to circulate air through the longitudinal aperture of the air chamber and out of the base aperture through the base conical section, and subsequently swung through the air at the end of the string producing the desired melodious and harmonious sounds. These sounds can be varied by varying the rotation and speed of rotation of the device, swinging through the air, by increasing or decreasing wrist and arm rotation of the user's hand holding the end of the holding member or string.
Accordingly, an object of the present invention is an instrument for achieving melodious and harmonious sounds, resembling those of tropical birds and animals.
A further object of the present invention is a method for operating the instrument for producing the melodious and harmonious sounds of birds and tropical animals, such that these sounds can be achieved as desired.
These objects and other objects of the present invention may be further understood by reference to the following non-limitative embodiments, as illustrated in the drawing figures, wherein
FIG. 1 is an exploded cross-sectional view of the present invention, taken on the line 1--1 of FIG. 3
FIG. 2 is an isometric cross-sectional view of the structure of the present invention,
FIG. 3 is a perspective view of the present invention illustrating the use and operation thereof and showing movement of the user's hand, and
FIG. 4 illustrates an example of the use of the present invention.
FIG. 5 shows a cross-sectional view taken on the line 5--5 of FIG. 3.
As illustrated in the drawing figures, the melody bird instrument is constructed with a resemblance to a rocket satellite, or command module of a satellite, in which a front conical shaped section 3 is located at the end of a substantially cylindrical hollow chamber 2 having a truncated hollow base conical section 1 secured to the opposite end of the central chamber 2. The central chamber 2 provides an air chamber through which air circulates through an elongated entrance slot at the periphery of the chamber 2 and out of a small hole 4 into the truncated hollow base conical section 1 through the open base portion. The circulation of air through the air chamber in this manner provides the melodious and harmonious sounds of the present invention, as hereinafter described.
The cylindrical central chamber 2, as well as the truncated cone 1, may be constructed of a plastic material, such as polyvinylchloride (PVC). This cylindrical member may have a length of two and 1/16 inches with a diameter of 13/16 inch.
The elongated slot 5, illustrated in FIG. 3, may be provided with dimensions being about 1/16 to 1/8 inch in width for the outside opening and a one and 7/8 inch to two inches in length. Moreover, this aperture or slot 5 is bevelled into the interior surface of the central chamber 2 such as to provide an angle between the surface of the interior of the aperture and the peripheral exterior surface of the chamber 2. This angle may be in the range of about 30.degree..
The opening 4 of the central chamber 2 into the base conical section 1 may have a diameter of 1/16 inch.
The front conical section 3 is secured to the end of the central chamber 2 opposite the base conical section, and includes two apertures 6, 7 at each end thereof, with the aperture 7 opening into the air chamber of the central chamber 2 and aperture 6 through the nose portion of the conical section 3 into the hollow interior thereof. This conical section 3 may also be constructed of PVC. For the operation of the device, a holding member, such as a nylon or polyester fiber string 11, is inserted through the apertures 6 and 7 into the air chamber, being also threaded through two plastic beads 8 and 9, as illustrated in FIG. 2, for the securing of the string to the melody bird assembly. The beads 8 and 9 may be of a plastic material and a small size such as a 5mm diameter. The bead 8 further provides a safety feature in that the end of the conical section 3 is blunted to avoid any damage occurring by striking of the assembly against an object. The string 11 is secured into the central chamber by knotting the end of the string after being threaded through a second smaller plastic ball 10 having a diameter of 3mm, for example.
The holding member 11 of nylon or polyester fiber string, for example, may have a length of 34 inches with a thickness of 1/32 inch, while the two apertures 6, 7 may have a diameter of 1/16 inch. Moreover, the end of the holding member 11 opposite the attachment to the melody bird assembly may be connected to a ring of a sufficient diameter, i. e. 7/8 to 1 inch, for inserting a finger to hold the structure in operation.
The operation of the melody bird instrument may be seen by reference to FIGS. 3 and 4. Namely, the instrument is rolled-up with the string, while holding the ring in one finger. Thereafter, the instrument is set free to descend, thereby starting rotation about its longitudinal axis. Simultaneously with this movement of the instrument, the wrist and arm of the holder are moved in a circular manner, as illustrated in FIGS. 3 and 4 such as to cause the instrument to swing in a circular fashion at a radius corresponding to the length of the holding member 11.
This motion of the instrument causes air to circulate through the air chamber of the central chamber 2 by entering the elongated aperture 5 and exiting the small opening 4. Such circulation of the air through the air chamber produces whistles and echoes within the walls of the air chamber so that the melodious and harmonious sounds are achieved. By varying the motion of the wrist and arm, i.e. by providing soft or strong pulls on the string, variations in the sounds produced occur such that the melodious singing sounds of different tropical birds can be achieved, as well as the sounds of night insects and animals.
The produced sounds are so resemblant of the sounds of singing birds, that some birds answer the sounds of the instrument and come into the area at which it is operated. As such, a useful bird calling instrument is also achieved by this construction.
While I have shown and described one embodiment in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as known to a person skilled in the art, and I therefore do not wish to be limited to the details shown and described herein but intend to cover all such changes and modifications as are obvious to one of ordinary skill in the art.
