     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a golf club swing training device. 
     2. Description of the Related Art 
     The prior art discloses training aids and auditory swing training aids. However, the prior art fails to provide an auditory feedback training aid for a golfer&#39;s face closure rate. 
     One example of a training aid is disclosed in U.S. Pat. No. 7,207,896 issued to Sudol for Aid for Training a Golf Swing. This patent discloses two laser pointers that are mounted at opposite ends of a bar that is affixed to a hat. The laser pointers are horizontally and vertically adjustable and are adjusted such that the laser beams from the two laser pointers cross at a desired point in front of the user. 
     Another example is U.S. Pat. No. 6,638,175 issued to Lee et al., for Diagnostic Golf Club System, which discloses a diagnostic golf club that has a plurality of strain gauges, an internal power supply, and a non-volatile memory for capturing data relating to a golf swing. The interface means is capable of transferring data from the diagnostic golf club to the computing means for processing the data and presenting the data in a useful and informative format. 
     Yet another example is U.S. Pat. No. 6,441,745 issued to Gates for Golf Club Swing Path, Speed and Grip Pressure Monitor, which discloses an acceleration monitor assembly for measuring acceleration forces on a golf club head during the swing of the golf club. 
     Golf is a difficult game and golfers routinely seek methods to improve performance. Practice and instruction are some primary paths to improving one&#39;s golf game. Because the swing mechanics of golf are a complex and often subtle series of timed movements of the golfer&#39;s body, learning is difficult without the aid of objective observation and feedback. One of the more important timed sequences is that of timing the lateral orientation of the club face to the velocity direction of the club center of mass, face angle along head path. The face angle rotation and closure rate cannot readily be observed by the golfer or instructor during the swing and the recognition of correlation between the face angle, body movements, and ball flight are disjointed such that learning is difficult. 
     BRIEF SUMMARY OF THE INVENTION 
     The present invention seeks to improve the feedback to the golfer relative to the rotation of the club head and thus provide valuable feedback to the golfer on the rate and timing of the club head rotation to golf ball impact. The present invention is a training and practice aid to accomplish such auditory feedback. 
     The device of the present invention comprises a housing with a rate sensor disposed within the housing. The rate sensor generates an electronic signal corresponding to an angular momentum generated by the golfer during a golf swing. Additionally, an amplifier circuit is disposed within the housing. The amplifier circuit is in electrical communication with the rate sensor. The amplifier circuit amplifies the electrical signal generated by the rate sensor to create an amplified signal. Also, a speaker is disposed within the housing. The speaker is in electrical communication with the amplifier circuit to generate an audible signal corresponding to the amplified signal. The audible signal has a pitch based on the angular momentum generated by the golfer during the golfer swing. Lastly, a power source is disposed within the housing. The power source provides power to the rate sensor, the amplifier circuit and the speaker. 
     The invention further comprises a method for using the device to provide auditory feedback to a golfer to improve the golfer&#39;s swing by closure of the face. The method comprises swinging a golf club having a device removably attached thereto. The device generates a first audible signal based on a first rotation of the golf club during the swing. 
     The golf club is swung a second time with a second rotation of the golf club during the swing. This second rotation of the golf club head generates a second audible signal based on a second rotation of the golf club during the swing. 
     Having briefly described the present invention, the above and further objects, features and advantages thereof will be recognized by those skilled in the pertinent art from the following detailed description of the invention when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in  FIG. 1 , the invention involves a modified golf club  150 . The present invention comprises a device  100  for attachment to a golf club  150  to provide auditory feedback to a golfer  200 . The device  100  comprises a housing with a rate sensor  101 , a speaker  102 , an amplifier circuit  103  and a power source  104 . The device  100  may be removeably attached to a shaft of a golf club  150 . 
     The rate sensor  101  generates an electronic signal corresponding to an angular momentum generated by the golfer  200  during a golf swing. The amplifier circuit  103  is in electrical communication with the rate sensor  101 , as indicated  FIG. 2 . The amplifier circuit  103  amplifies the electrical signal generated by the rate sensor  101  to create an amplified signal. As shown in  FIG. 2 , the speaker  102  is in electrical communication with the amplifier circuit  103  to generate an audible signal corresponding to the amplified signal. The power source  104  provides power to the rate sensor  101 , the amplifier circuit  103  and the speaker  102 . 
     The frequency of the generated sound corresponds to the rotation rate of the club  150  when swung by a golfer  200 . The invention further comprises a method for using the device  100  to provide auditory feedback to a golfer to improve the golfer&#39;s swing by closure of the face. 
     As shown in  FIG. 2 , the device  100  preferably utilizes a rate sensor  101 , a power source (such as a battery)  104 , a miniature speaker component  102 , and an amplifier circuit  103  to convert club head rotation rates into sound. The frequency of the emitted sound will correspond to the rotation rate of the club  150 . The device  100  will be mounted on a golf club  150  shaft and is preferably detachable such that the device  100  can be used for practice and the golf club  150  can be converted back to approved form for competitive rounds of golf according to the Rules of Golf as set forth by the USGA. 
     Preferably the device  100  is mounted closer to a golfer  200  on a golf club shaft  150  than farther from the golfer  200 , and the speaker  102  of the device  100  is preferably oriented toward the golfer  200 . 
     For each swing and each golfer  200  there is preferably a different profile for the sound of the device  100 . 
     The method of the present invention comprises swinging a golf club having a device  100  removably attached thereto. The device  100  generates a first audible signal based on a first rotation of the golf club  150  during the swing. The golf club  150  is swung a second time with a second rotation of the golf club  150  during the swing. This second rotation of the golf club  150  head generates a second audible signal based on a second rotation of the golf club  150  during the swing. The golfer  200  quickly learns to recognize the rate of the pitch and/or amplitude change and learns to relate the sound to the timing of the face position of the golf club  150 . The auditory feedback enables the golfer  200  to improve the golfer&#39;s  200  game.
