     BACKGROUND 
     This invention relates to wild game calls apparatus and methods for producing a wide range of game calls (e.g., from quiet to loud chirps, mews, bugling, and estrous whines). 
     The sport of hunting often requires the use of game calls in order to attract or locate an animal being hunted. Also, wildlife enthusiasts often require the use of game calls in order to attract or locate animals to observe in their natural habitat. 
     Different types of calls have been invented for the use in outdoor hunting sports and for the use by wildlife enthusiasts. Separate game calls have been devised that are designed to attract certain animals, such as turkeys, deer, elk, moose, coyotes, etc. Normally, these game calls are specialized as to the type of the animal sought, or even to the type of animal sound meant to be mimicked, such as the grunt of a red deer. 
     Oftentimes, game calls allow the users to change the length of the vibration of the reed in order to change the sound of the call. Other devices contain different chambers to mimic the sounds made by a wide variety of different animals, where restrictions to the airflow to the chambers changes the tone of the call. Other types of devices have been designed to allow the user to change the sound produced by a device. The sound can be changed by the user restricting airflow by the means of his or her finger. 
     Many animals hear frequencies that humans do not hear. Most all wild game species produce a vocal call by utilizing a set of vocal cords generating a sound resounding through throat and nasal passages having various lengths, diameters, and other characteristic lengths. Each set of vocal cords in combination with various resonant cavities will produce a similar, but different sound wave pattern. Many of the instruments made to attract or locate animals do not necessary mimic these frequencies that are located above or below human hearing. 
     SUMMARY OF THE INVENTION 
     A wild game call may include a resonance piece and a mouth piece. The resonance piece may include a body, pipes, and a plug that may attach to a mouth piece. The resonance piece may be attached to the mouth piece. The body may be cylinder shaped. The pipes may be located on the distal end of the body. 
     Also a wild game call may include a mouth piece attached to the body. Additionally, the mouth piece may include a reed and a neck. The reed and the neck may be attached to the resonance piece by placing the reed and the need in the resonance piece and placing a plug in the remaining open area. The plug may squeeze or otherwise attach the mouth piece to the resonance piece. 
     Alternatively, a wild game call may include pipes of variable lengths attached to a splitter, which combines two pipe openings into one pipe opening. Also, a front pipe may be attached to the one pipe opening of the splitter. Additionally, a wild game call may include a mouthpiece attached to the front pipe comprising openings for exhaling, a reed; and fasteners to attach the reed to the mouth piece.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     It will be readily understood that the components of the present invention, as generally described and illustrated in the drawings herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the system and methods of the present invention, as represented in the drawings, is not intended to limit the scope of the invention, but is merely representative of various embodiments in accordance with the invention. The illustrated embodiments will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. 
     It has been found that animals have voices, just as humans have voices. That is, that the tone quality, the various resonant frequencies, the overall timbre of the voice of an animal may be unique to that species, as well as unique to an individual animal. The human ear hears voices, and the human mind distinguishes voices of individuals. Previous systems for bugles, game calls, and the like have often reflected very minimal ranges of frequency, residence. Accordingly, in a game call in accordance with the invention, at least two varieties of calls may rely on a combination of significant lengths (diameters, lengths, widths, etc., as used in an engineering and acoustical sense). 
     Accordingly, it has been found that the frequencies of sound emitted by an animal when it is generating sounds for some purpose may be analyzed. Accordingly, it has been found that the frequency response compares with or correlates with various aspects of the anatomy of the animal. For example, the throat portion of an animal has several characteristics lengths including minimum diameter, maximum diameter, length, and the like. Likewise, the mouth of an animal has a characteristic length of a diameter and may have multiple dimensions of diameter, width, etc. Similarly, the nasal passages of an animal have characteristic lengths, several characteristic diameters, various locations where widths can be measured, and provide an effect on sound. 
     Accordingly, in order to provide a sound that replicates the multiple frequencies generated within the head of an animal, and the throat thereof, beyond the vocal cords, are not replicated in prior art systems. Accordingly, in accordance with the invention, the inventor has analyzed the frequency distribution of calls made by various animals, for example, elk calls provide a sound that appears to be a whine of changing pitch. Likewise, that sound when analyzed spectrographically provides various frequencies over time, and various frequencies that occur simultaneously. Accordingly, it is possible to create resident chambers or pipes, just as organ pipes, tuned to provide various characteristic lengths (widths, diameters, lengths, etc.) in order to generate artificially the distribution of frequencies in the sounds generated. This physical phenomenon is driven by an initial sound generator to replicate the vibration of vocal cords. It has been found that the sound generator need not be a vocal chord assembly. That is, various types of vibration mechanisms may be implemented, generating a broad variety of frequencies. Accordingly, by attaching to the sound generator various chambers having selected characteristic lengths, the selected frequencies, associated with the selected wave lengths dictated by the characteristic lengths, may be optimized due to resonance around the energy of the original signal. 
     Accordingly, in one embodiment, an elk call may be made, or a call for another animal having characteristic passages that all receive their sound stimulus from a single sound generator (for example, a reed, a diaphragm, a flexible member, a vibrational member, or the like). Likewise, in a particular embodiment of a bugle type of call, resonance chambers may be selected to provide a variety of preferred resonant frequencies. 
     As a general matter it has been found that multiple chambers fed from a single sound generator provide a better, and better matched, set of frequencies of sound. The difference between prior art game calls, and game calls in accordance with the invention may be distinguished by the lack of texture or lack of variety and lack of intensities, in distribution of the proper frequencies. 
     Accordingly, in an apparatus and method in accordance with the invention, experiments were conducted with various passages, and with the various characteristic lengths of those passages (for example, pipes, tubes, etc.) in order to replicate the proper texture or distribution of frequencies of sound from an actual recording of an animal. 
     An apparatus  10  in accordance with the present invention may include a resonance piece  12  and a mouth piece  14 . The resonance piece  12  may be attached to the mouth piece  14 . In selected embodiments, a mouth piece  14  may be placed in a person&#39;s mouth and the person may exhale into the mouth piece  14  while controlling lip pressure on the reed  16 . As a result of the exhale, the resonance piece  12  may offer multiple resonant chambers for a sound, or sounds. 
     Referring to  FIG. 1-4 , the resonance piece  12  may include a body  20 , pipes  22 ,  24 , and a plug  26 . The resonance piece  12  may be formed of any suitable material. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, sound, or the like. In selected embodiments, the resonance piece  12  may be formed of wood, plastic, metal, or other durable resonant products.

Alternatively, the resonance piece  12  and the mouth piece  14  may be machined, cast, molded, or otherwise formed as a single, monolithic unit. In one embodiment, a plug  26  fitted to the resonance piece  12  wedges against the reed  16 , opposite the mouth piece  14  after insertion of the mouth piece  14  and the reed  16  into the resonance piece  12 . 
     The mouth piece  14  has a channel along its lengths, under the reed  16 . The channel may have additional relief on the sides and at the end tip of the channel. The channel may preclude complete closure. 
     The reed  16  may be formed of any suitable, stiff yet flexible, material that will create a vibration or “disturbance” to cause a desired noise or tone. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, sound, or the like. In selected embodiments, the reed  16  may be formed of plastic or plastic like products. 
     Additionally, the reed  16  may be flexible. For example, the reed  16  may be formed of a flexible material (e.g., flexible plastic), such as PET or mylar, suitable sized. 
     Also, the neck  18  may be shaped in any suitable form. In selected embodiments, the neck  18  may be formed as a portion of a cylinder. For example, the neck  18  may be shaped as a portion of a cylinder cut lengthwise thinning toward a distal end away from the reed  16 . Additionally, the cylinder cut neck  18  may be hollow. 
     Additionally, in selected embodiments, the reed  16  may cover the any suitable area of the neck  18 . For example, the reed  16  may cover the hollow area of the neck  18 . In addition, the reed  16  may be formed of a flexible material (e.g., flexible plastic), thus, the reed  16  may move (e.g., vibrate) over the hollow area of the neck  18  producing a sound. 
     The body  20  may be formed of any suitable material. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, sound, or the like. In selected embodiments, the body  20  may be formed of plastic or plastic like products. The body  20  may be shaped in any suitable form. In selected embodiments, the body  20  may be cylinder shaped. 
     Additionally, in selected embodiments, the body  20  includes pipes  22 ,  24 . The pipes  22 ,  24  may be shaped in any form suitable. For example, a pipe  22  may be shaped larger than another pipe  24 . Also, the pipes  22 ,  24  may be shaped in different forms (e.g., circular, oval, square, rectangular, etc) and include different numbers (e.g., one pipe, two pipes, three pipes, etc). All the pipes  22 ,  24  are divided from each other in the body and resonate with sound produced by the same reed  16 . 
     The pipes  22 ,  24  may be located at on any suitable part of the body  20 . For example, in certain embodiments, the pipes  22 ,  24  may be located on the front of the apparatus  10 . 
     The plug  26  may be formed of any suitable material. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, or the like. The plug  26  may be located at any suitable located on the body  20 . For example, in selected embodiments, the plug  26  may be located in the rear of the body  20 . Additionally, in selected embodiments, the plug  26  may be located above the reed  16  and the neck  18  holding the reed  16  and the neck  18  in a locked position. 
     Referring to  FIGS. 5 and 6 , as well as  FIGS. 1-4  the apparatus  10  includes a splitting system. The splitting system may include pipes  28 , 30 , a front pipe  32 , a mouth piece  34 , a reed  36 , fasteners  38 , and a splitter  40 . 
     The pipes  28 ,  30  may be formed of any suitable material. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, or the like. In selected embodiments, the pipes  28 ,  30  may be formed of aluminum or plastic like products. 
     The pipes  28 ,  30  may be formed of any suitable length. Likewise, the pipes  28 ,  30  may include different lengths and diameters independent of each other downstream of their mutual separation. 
     The pipes  28 ,  30  may be formed with or otherwise connected to splitter  40  in any suitable manner. For example, in selected embodiments, the pipes  28 ,  30  may be glued and sealed with silicon to the splitter  40 . Alternatively, the pipes  28 ,  30  and the splitter  40  may be machined, cast, molded, or otherwise formed as a single, monolithic unit. 
     The front pipe  32  may be formed of any suitable material. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, or the like. In selected embodiments, the front pipe  32  may be formed of aluminum or plastic like products. 
     The front pipe  32  may be connected to the splitter  40  in any suitable manner. For example, in selected embodiments, the front pipe  32  may be glued and sealed with silicon to the splitter  40 . Alternatively, the front pipe  32  and the splitter  40  may be machined, cast, molded, or otherwise formed as a single, monolithic unit. 
     The mouth piece  34  may be formed of any suitable material. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, or the like. In selected embodiments, the mouth piece  34  may be formed of aluminum or plastic like products. 
     The mouth piece  34  may include openings  42 . The mouth piece  34  may be shaped in any suitable shape. For example, in selected embodiments, the mouth piece  34  may be shaped as a cylinder thinning toward a distal end. In selected embodiments, the openings  42  may be located at the distal end of the mouth piece  34 . 
     A reed  36  may be formed of any suitable material. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, or the like. The reed  36  may be used to cover the openings  42 . For example, in selected embodiments, the reed  36  may be used to cover one of the openings  42 , or all or the openings  42 . 
     The reed  36  may be attached or otherwise connected to the mouth piece  34  by fasteners  38 . For example, the fasteners  38  may squeeze or otherwise attach the reed  36  to the mouth piece  34 . The fasteners  38  may be formed of any suitable material, such as rubber, aluminum, plastic, etc. 
     The splitter  40  may be formed of any suitable material. Suitable material may be selected to provide a desired strength, rigidity, cost, durability, or the like. For example, in selected embodiments, the splitter  40  may be formed of aluminum, or plastic like products. 
     The splitter  40  may include a mechanism that makes one pipe opening separate into two pipe openings. For example, at one side of the splitter  40  there may be one pipe opening, and on the other side of the splitter  40  there may be two pipe openings. 
     The openings  42  may be shaped in any suitable form. The openings  42  may be located on the distal end of the mouth piece  34 . A person may exhale into the openings  42 . For example, a person may place his or her mouth over the openings  42  and exhale into the openings  42 . 
     Referring to  FIG. 7 , various lengths and diameters may be provided for the various pipes  28 ,  30  in the bugle  10 , or other calls  10 . Likewise, various connection mechanisms may be provided in order to connect a mouthpiece  34  to a splitter  40  prior to entry of sound into the multiple pipes  28 ,  30  of the apparatus  10 . Likewise, the length of the front pipe  32  that acts as an initial residence chamber just beyond the mouthpiece  34  may be selected. Similarly, the diameter may be selected in accordance with a desired frequency response. 
     Referring to  FIG. 8 , in one embodiment of an apparatus  10  in accordance with the invention, the mouthpiece  34  may actually be formed to have an initial neck portion  52  having various characteristic dimensions, including the characteristic lengths or dimensions of an opening  42 . Referring to  FIG. 10 , the opening  42  in one embodiment is open approximately half way across the area of the open cross-section of the neck portion  52 . In the illustrated embodiment, a reed  36  is attached by connectors  38  that act as compression clamps to hold the reed in place. Accordingly, the tensions in reed  36  may be selected to provide the appropriate initial frequencies. In one embodiment, the lips of a user may be pursed across the opening  42 , one lip touching on the reed  36  and the other lip touching on the edge of the opening of the neck  52 . Accordingly, by various breaths, vocalizations, as well as trumpeting, of the lips, a user may create a variety and range of sounds through and across the reed  36 , into the mouth piece  34 . In general, a bell  54  may be provided to have characteristic lengths typical of the animal pursued. In one embodiment the bell  54  may be formed to connect to another pipe  32  that has been sized to provide resonant frequencies corresponding to the throat of an animal sought. Meanwhile, the splitter  40  divides the flow between two other characteristic pipes  28 ,  30 . The pipes  28 ,  30  may correspond in general to the nasal passages, and oral passages respectively of the animal. Accordingly, the lengths  62 ,  64  of the pipes  28 ,  30  may also be selected to provide the effective frequencies. Similarly, the diameters of the pipes  28 ,  30  may be chosen as a single diameter each, a tapered diameter, or a convoluted multiple diameter in order to provide the characteristic frequencies. Likewise, the lengths  60  as well as the diameter or diameters of the pipe  32  may be selected to provide the richness of the texture of the resonant frequencies available in corresponding to the throat of an animal. Thus, the sound generator  36  generates an initial sound that resonants within the mouthpiece  34  and pipe  32 , according to the characteristic lengths thereof in order to provide a set of desired frequencies in the texture of the sound. Likewise, the characteristic lengths  62 ,  64  in combination with the characteristic dimensions or lengths of the splitter  40  provide the characteristic frequencies generated by the pipes  28 ,  30  representing those additional frequencies or resonant frequencies in the vocalizations by an animal. 
     Referring to  FIG. 9 , in an apparatus  10  in accordance with the invention one embodiment of a game call may include a body  20  provided with pipes  22 ,  24  having disperate diameters or effective diameters. That is, a width  23  of a pipe  22 , and a width  25  of a pipe  24  may each have their own characteristic dimension, while each of the pipes  22 ,  24  has an alternative diameter or effective length identified, respectively, as the width  66 , and width  68 . Or diameter  66 , and diameter  68 . In general, referring to  FIGS. 9-12 , the apparatus  10  may include a mouthpiece  14  having a neck  18  or bed  18  that receives a reed  16 . The reed  16  may be held in place within an opening in the body  20  by a plug  26 . In one embodiment of an apparatus and method in accordance with the invention, an opening in the body  20  may be formed by a core portion  46  or a chamber core  46 . That is, the chamber core  46  forms a chamber into which fits both the neck or bed  18 , and the plug  26  having the reed  16  wedged there between. Thus, the friction fit of the plug  26  and the neck or bed  18  together with the reed  16  there between holds all three pieces within the chamber or portion of the body  20  formed by the core  46 . That is, in general, the core  44  represents a flexible material formed to replicate the passages, and thus be a pattern or core to define the pipes  22 ,  24 . 
     In the illustrated embodiment, the two branches  48 ,  49  of the core  44  correspond to the pipes  22 ,  24  respectively. 
     As a practical matter, it has been found that the sound generator  16 ,  36  of an apparatus in accordance with the method is often not so important to the overall sound quality or spectrum of frequencies acoustically available as considered by some developers in the prior art. Rather, the resonant frequencies of the various pipes  28 ,  30 ,  32 ,  22 ,  24  appear to control the resonance, so long as some initial frequency is available to generate that particular resonant frequency supported by the significant lengths of the various pipes  22 ,  24 ,  28 ,  30 ,  32 ,  34 ,  40 . 
     Under the reed  16  of  FIGS. 9-11  a channel is formed to extend axially along the length of the bed  18  or neck  18 . The channel provides an opening all the way through into the body  20 , until the air associated with the generation of sound on the reed  16  is discharged into the various pipes  22 ,  24 . In certain embodiments of an apparatus  10  in accordance with the invention, relief may be provided by way of additional removal of material corresponding to each lateral side of the reed  16  extending axially along the sides of the channel in the bed  18 . Accordingly, the reed  16  is effectively precluded from closing down against the bed  18 . Also, to that same result, relief is formed in the opening end of the channel near the extreme upper end of the reed as illustrated in  FIG. 9 , in order that the reed can never be closed down, as a practical matter, by a user, when in use. Accordingly, various squawks and squeaks are avoided an a consistent tone is easily obtained by a user in using the apparatus  10  in accordance with the invention. 
     The wild game call may produce a wide range of calls. The user can, with a little practice, create chirps, mews, and estrous whines. Additionally, the user may produce from very soft, quiet calls to loud calls for locating elk at long distances. 
     For example, one method of use for a cow call may be for a user to use his or her top lip to apply firm pressure to the reed. Too much pressure may cause the reed to stick, while too little will not produce a clean high note. If need be, a user may pull the lip slightly over the teeth. Also, a user may begin the call with his or her lip approximately between about ⅛ inch and about ¼ inch from the tip of the reed. A user may blow air into the call, and keep his or her mouth in a letter “E”. This will produce the high note. A user may finish the call by letting his or her mouth relax slightly as if the user was saying the letter “O”, at the same time reduce the amount of air the user is blowing into the call. 
     Another example, and another method of use may be for a user to begin and end the call in the same manner, but when finishing the call the user may move his or her lip along the reed away from the tip at the same time relax his or her mouth and reduce the air. Some people will actually let there lip roll back over their teeth with this method. 
     Additionally, chirp sounds (e.g., a very short call) may be about ½ second, mew sounds (e.g., a longer call) may be between about one and about two seconds, and estrous sounds (e.g., a long whine) may be between about two and about three seconds. 
     A user may produce soft quiet calls by using less air. Loud calls are best produced by starting the call slightly further from the reed tip and use more air. The user may adjust the reed by moving it out for a lower pitch, in for the higher pitch. Also, very little movement will change the pitch. The reed should not extend past the soundboard (bed or neck of mouthpiece).
