referring more specifically to the drawings , and to fig1 in particular , numeral 10 designates generally a musical cap embodying the present invention . the cap shown here is a baseball - type cap ; however , any suitable head covering means may be used for the present invention , such as , for example , cowboy hats , basic visors , or standard fedora - type hats . the hat will normally , but not necessarily , include a bill or brim , such as bill 12 shown here , and , for purposes of this application and the claims appended hereto , the terms &# 34 ; bill &# 34 ; and &# 34 ; brim &# 34 ; will be used interchangeably and are referred to generally as visor means . similarly , the musical device described herein , in combination with the baseball cap 10 , has been programmed to play &# 34 ; take me out to the ball game &# 34 ; when activated , and thus would be appropriate for wearing to a baseball game , for example . any tune may be programmed into a particular musical device and will normally be , in some way , associated with or appropriate for the type of hat or cap and the occasion for which it is intended . for example , a musical device programmed to play &# 34 ; pomp and circumstance &# 34 ; or the school song may be incorporated into the mortar board worn by students at graduation ceremonies . the hat or cap 10 includes a compartment 14 in bill 12 for housing a musical device 16 . the musical device is inconspicuously housed within compartment 14 , as shown in fig2 and 4 , and includes a suitable power source , such as batteries 18 or a small solar unit , a programmed electronic chip 20 , and a speaker unit 22 . extending laterally from the musical device toward the front of the hat is a suitable switch means 24 for selectively activating the musical device . the device may be fastened within the compartment in any suitable manner , a preferred method being the use of a releasable adhesive which permits removal of one device and the substitution of another to change tunes , for example . as seen in fig3 and 5 , compartment 14 is formed by separating a flap or layer of cloth 26 , which forms part of the bottom surface of bill 12 , from the adjacent layer or layers which form the remainder of the bill . in this case , the bill has a stiffening means , such as a layer of cardboard 28 , disposed therein , and a top layer of cloth 30 . the cardboard layer in the embodiment shown has been trimmed to accommodate the musical device , however , the device has minimal thickness and may also be surface mounted onto the stiffening layer . flap 26 includes a suitable fastening means around the border thereof , such as the hook and loop material sold under the trademark &# 34 ; velcro &# 34 ;. the flap contains the hook portion 42 and the bill contains the loop portion 44 , these positions being interchangeable . the flap is designed to provide access to the musical device for changing batteries , for example , or for removing a particular device and inserting another . the compartment may be formed in any hat or cap , either by separating the multiple layers which form the visor means , or by adding a covering means or flap of suitable size to a single layer visor . the compartment also has minimal thickness , as shown in fig3 and 4 , making it unobtrusive and ensuring that it does not obstruct the line of vision of the wearer . switch means 24 has normally separated contact arms 46 and 48 for activating the musical device . the arms are disposed near the outer periphery of bill 12 , this being the area of the bill which is normally grasped for tipping the hat . the contact arms are sensitive to a slight pressure , such that a light touch applied to the bill in the general vicinity of the contact arms will deflect flap 26 sufficiently to bring the contact arms into engagement , thereby activating the musical device , as shown in fig1 . it is not necessary to maintain the contact between arms 46 and 48 , as the device begins to play its tune upon activation and continues to play as programmed . for example , the musical device shown herein plays two choruses of &# 34 ; take me out to the ball game &# 34 ; upon activation , aand then ceases to play until activated again . in the use and operation of the present musical cap 10 , the visor means or bill 12 of the cap is prepared to receive the musical device . one or more of the layers which form the bill are separated from the adjacent layer or layers to form a compartment 14 in the bill , or the musical device may be surface mounted onto a single layer visor with a suitable cover means added . the musical device may be secured within the compartment in any convenient manner , such as by the use of a releasable adhesive , which permits substitution of one device for another . the separation of layers , or the addition of a cover layer , provides a covering means or flap 26 to protect and conceal the device within the bill . the flap has a releasable fastening means such as a hook and loop fastener with , for example , the hook portion 42 disposed on the flap and the loop portion 44 disposed on the bill . this provides access for changing batteries , for example , or for changing to a device that plays a different tune . the device is mounted in the compartment with the switch contact arms 46 and 48 oriented toward the front of the hat or cap , and the flap 26 is fastened in place over the musical device . slight contact pressure applied to the flap anywhere in the general vicinity of the switch meaans 24 , such as that applied when the bill of the cap is grasped for tipping or waving the hat , is sufficient to activate the musical device . once activated , contact between the switch arms 46 and 48 need not be maintained , since the device will play as programmed and then stop . for example , the device may be programmed to play a single chorus of &# 34 ; home on the range &# 34 ; and then stop , until contact pressure is again applied in the switch area to reactivate the device . in the claims , the word &# 34 ; hat &# 34 ; is used generically and means and includes all head coverings mentioned herein , including caps , unless otherwise indicated or defined . while one embodiment of a musical hat and modifications thereof have been shown and described in detail herein , various other changes and modifications may be made without departing from the scope of the present invention .
a musical hat , cap or similar head covering is disclosed , having a visor portion with a compartment formed therein near the frontal portion of the visor . a musical device is disposed in the compartment and includes a switch for activating the musical device . the switch may be so located that grasping the hat by the visor in the vicinity of the switch , for tipping or waving the hat , activates the musical device which plays a short tune and then stops until reactivated .
