RELATED APPLICATIONS 
   The present application is claims priority to U.S. Provisional Patent Application No. 60/715,966, filed Sep. 9, 2005, the contents of which are incorporated herein by reference and U.S. Provisional Patent Application No. 60/793,099, filed Apr. 19, 2006, the contents of which are incorporated herein by reference. 

   FIELD OF THE INVENTION 
   The invention relates to refrigerators. More specifically, the invention relates to refrigerators that incorporate an audio playback device. 
   BACKGROUND OF THE INVENTION 
   Obviously, various types of refrigeration units, such as freezers and coolers, are long known in the art. Many times refrigeration units, some of which have glass doors, are used in retail environments in order to sell products that need to be cooled or frozen. Because the refrigeration unit is being used to sell a product, the more attention that the refrigeration unit gets from passing customers, the greater the likelihood the items inside will be sold. However, in the past, refrigeration units have only incorporated visual effects in order to attract the attention of passing customers. While successful, visual effects will not grab the attention of a busy customer, particularly when the customer has become desensitized to the visual effect due to having seen it many times or due to being placed near competing products also attempting to obtain the customer&#39;s attention using a visual effect 
   SUMMARY OF THE INVENTION 
   The present invention provides a refrigerator comprising a refrigeration unit comprising a cabinet and a door. The cabinet contains a plurality of items to be cooled or frozen. The refrigerator also comprises an audio playback device comprising a memory and a speaker. The audio playback device is adapted to store a recorded audio soundtrack on the memory and play the recorded audio soundtrack through an audio speaker.

   DESCRIPTION OF THE PREFERRED EMBODIMENT 
   While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated. 
   Referring to  FIGS. 1-3 , the present invention provides a refrigeration unit  10 , such as a refrigeration unit model number GDM-10 manufactured by True Manufacturing Co. Inc., the assignee of the present application. The refrigeration unit  10  may also comprise a vending machine. On a top exterior surface of the refrigeration unit  12  is placed an audio playback device  14 . The audio playback device  14  is preferably a digital music player incorporating a memory onto which multiple audio tracks or songs may be recorded and is attached to one or more audio speakers. The memory is preferably solid-state memory because it is more resistant to physical shock and vibration while the refrigeration unit is moved and because it is inexpensive and compact. However, the memory may also be a compact hard drive, a compact disc (CD), digital versatile disk (DVD), or a magnetic tape or other known audio storage and playback device. 
   Referring to  FIG. 5 , in the embodiment displayed, the audio playback device  14  comprises an IPOD musical storage system made by Apple Computer, Inc of Cupertino, Calif. Additionally, the audio playback device  14  comprises a BOSE SOUNDDOCK sound transmission system made by Bose Corporation of Framingham, Mass. Alternatively, the audio playback device  14  may constitute a single unitary device comprising a memory and speakers. 
   The audio playback device  14  is oriented such that its speakers, located on a top surface  16  thereof, are directed upwardly so that sound will be transmitted in all directions. Placed over the audio playback device  14  is cover  18  having a plurality of apertures  20  therein. The apertures are preferably a plurality of circular apertures, but may also be louvers, a single large aperture or other means for allowing sound to transmit through the cover  18  from the audio playback device  14 . The audio playback device  14  preferably receives its power from the refrigeration unit  10 , although it may be separately powered. 
   Also provided within the cover  18  is a secondary aperture  22  that allows a portion of the audio playback device  14  to extend therethrough. The portion of the audio playback device  14  extending through the cover  18  has a volume control and various playback controls that allow the volume to be adjusted and the playback mode to be adjusted. 
   The cover  18  preferably allows sound to clearly transmit therethrough, but also provides security for the audio playback device  14  so that it will not be stolen. 
   In use, the audio playback device  14  and refrigeration unit  10  are placed in a location where a customer will readily see the refrigeration unit  10  and may also include visual effects which attract a customer&#39;s attention. The audio playback device  14  may be programmed to play a certain track repetitively, play a collection of tracks in order or play a collection of tracks randomly. The tracks may include advertising messages, popular music or a combination of the two. 
   It is further contemplated that the audio playback device can be either manually started and stopped, operate on a time schedule, include a photo sensor and play only when light is detected, a motion sensor and play only when motion near the refrigeration unit is detected, or a door switch which causes the device  14  to play only when the door has or has not been opened within a period of time. 
   An alternative embodiment not depicted allows more of the audio playback device  14  to extend through the cover  18  so that a user can see a visual display associated with the device  14  and receive the feedback provided through the device  14  to manipulate user controls. 
   Referring to  FIGS. 6 and 7 , an improved system for mounting the audio playback device and light is disclosed. The system includes a first mounting bracket  24  mounted to the top of the refrigeration unit  10 . Attached to the mounting bracket  24  is a light  25  ( FIG. 7 ), such as a fluorescent light for lighting a display  26  associated with a cover  28 . While the invention is described in terms of a fluorescent light, one of ordinary skill in the art would recognize the other types of lights may be used, such as incandescent lights or light emitting diodes. 
   A second bracket  30  is mounted to the top of the refrigeration unit  10  rearwardly of the first bracket  24 . The second bracket  30  has a recessed top surface  32  upon which the audio playback device  14  is mounted. The top surface  32  is preferably rotated at an angle with respect to the horizontal upper surface of the refrigeration unit  10 , such that an audio playback device  14  mounted thereto is pointed upwardly at a slight angle. In this manner, the audio playback device  14  being rotated with respect to the flat upper surface of the refrigeration unit  10  will project sound further from the refrigeration unit and through the cover  28 . 
   The cover  28  defines a plurality of apertures  34  in an upper surface, which allows sound from the audio playback device  14  to travel unobstructed to a listener located near the refrigeration unit  10 . A lock  36  is also mounted upon the top of the refrigeration unit  10 , which locks a lock extension tab  40  of the cover  28  to the refrigeration unit  10  to secure the audio playback device  14  from theft. L-channel constituting a protrusion  38  is further mounted to the top of the refrigeration unit  10  to provide a mounting flange for the cover  28  to prevent the cover from it sliding to the left or the right or forward or rearward after it has been locked to the refrigeration unit  10 . The cover  28  may also be attached to the protrusion  38  by a fastener. 
   The refrigerator is made with a special plastic cabinet top, shaped in such a manner, as to enclose the lighting of an advertising sign and the IPOD sound system. 
   The refrigerator has electrical power on top of the cabinet for the fluorescent lighting ballast. The BOSE SOUNDDOCK system is electrically connected, so that it is permanently connected. A sheet metal bracket holds the BOSE SOUNDDOCK system at a determined angle, so that it is pointed upward, against the vacuum-formed plastic cabinet top. The bracket is fastened with screws to the cabinet top. The cabinet top has several hundred apertures drilled into it, to allow the sound through. This area of apertures is aligned with the speaker. In the cabinet top, there is also a rectangular hole, which allows the BOSE SOUNDDOCK system through. The IPOD is then pushed into the BOSE SOUNDDOCK system, which allows for continuous music, as the Bose system maintains battery life. This BOSE SOUNDDOCK system also has volume control, where the customer can increase or decrease the volume. The IPOD can also be removed for safe storage and/or re-programming 
   While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention, and the scope of protection is only limited by the scope of the accompanying claims.
