Abstract
An assembly that affords easy application of a phone cover of thin, flexible, resiliently stretchable material around a bulbous phone (e.g., a microphone or earphone such as an ear bud). The assembly includes the phone cover that defines a socket adapted to closely receive the phone, and also includes a frame of stiff material having a passageway from which the phone cover is supported with an inlet opening to the socket aligned with the passageway on the frame. The phone can be moved along the passageway into the socket in the phone cover, whereupon the phone cover is separated from the frame.
Description




FIELD OF THE INVENTION




The present invention relates to covers for bulbous phones including microphones and ear phones, and particularly including ear phones of the type called ear buds that are small speakers for radios, recorded music players, and the like, that are inserted into the bowl of the ear so that only the wearer of the ear bud can hear sound from the speaker. Such a phone cover is typically of thin, flexible, resiliently stretchable sound transmissive material, defines a socket, and is adapted to closely receive a phone inserted into the socket through an inlet opening.




BACKGROUND OF THE INVENTION




Small bulbous earphones, including a type called ear buds, are commonly used for radios, recorded music players, cell phones, walky-talkies, and the like. An ear bud can be inserted into the bowl of the ear so that only the wearer of the ear bud can hear sound transmitted through it. Covers of thin, flexible, resiliently flexible, sound transmissive material are available for such ear buds. Those covers define sockets adapted to closely receive car buds inserted into the sockets through inlet openings. Such a cover provides a cushion between the ear bud and an ear into which it is inserted, provides friction with the ear to help hold the ear bud in the ear, and provides a cerumen guard for the ear bud. It is sometimes desirable to change the cover on an ear bud, such as when the cover has collected an excessive amount of contaminants either from a users ear or from some other source when the covered ear bud is removed from the ear, or between uses of the ear bud by different users to preclude carrying cerumen from one persons ear to another. While replacement ear bud covers are commercially available, they are so thin, flexible, and resiliently stretchable that they are difficult for many individuals to place over the car buds.




DISCLOSURE OF THE INVENTION




The present invention provides a phone cover in an assembly that affords easy application of a phone cover around a bulbous phone such as an ear bud, even by persons with limited manual dexterity.




The phone cover in the assembly according to the present invention is of thin, flexible, resiliently stretchable material that defines a socket and is adapted to closely receive a phone in the socket. The assembly includes a frame of stiff material. The phone cover is supported from the frame with an inlet opening to the socket aligned with a passageway defined by the frame. The phone or ear bud can be moved along the passageway into the socket in the phone cover; whereupon the cover on the phone can be easily separated from the frame.




Using this assembly a phone such as an ear bud can be covered by simply supporting the frame (manually or otherwise) while moving the phone along the passageway defined by the frame into the socket in the phone cover; and separating the phone with the cover around it from the frame.




In certain embodiments of the assembly described herein the passageway defined by the frame is a through opening in the frame that is generally circular, and the phone cover is supported from the frame by a support layer of thin flexible material attached to the phone cover along and around its inlet opening and extending outwardly from the phone cover to a portion of the frame that defines the through opening. The phone cover includes an outer part of sound transmissive material having a generally circular periphery, and an adjacent washer-like part having a circular outer periphery bonded to the periphery of the outer part and having a concentric circular inner edge portion defining a through opening and being bonded to the support layer. The phone cover has lines of weakness adjacent that inner edge portion to afford separation of the phone cover from the frame. Also, the support layer and/or the frame can have lines of weakness to afford manually separating them into parts to facilitate removal of the phone with the cover around it from the support layer and/or the frame.




In other embodiments of the assembly described herein the phone cover is defined by two pieces of sheet material each including a bulbous portion that is generally bulbous shaped about a central axis and has a base with opposite sides. The peripheries of the bulbous portions of the pieces of sheet material are bonded together so that those bulbous portions form the phone cover. One or both of the pieces of sheet material also have support portions with edges extending away from opposite sides of the bases of the bulbous portions. Those support portions are attached to a portions of the frame that define the passageway to provide a support layer between the frame and the inlet opening to the socket in the phone cover. The pieces of sheet material can have lines of weakness between their bulbous portions and their support portions to afford separation of the phone cover from support layer; and, if needed, the support layer and/or the frame can include lines of weakness along which they can be broken to facilitate removal of the phone with the cover around it from the frame and/or the support layer. In one of those embodiments the passageway is a generally circular through opening, a support portion is provided on both pieces of sheet material, and the phone cover projects with the axis of the bulbous portions disposed at about a right angle to the major surfaces of the frame. In the other of those embodiments the passageway extends along one side of the frame, a support portion is provided on one or on both pieces of sheet material, and the phone cover is aligned with the passageway with the axis of the bulbous portions disposed generally parallel to the major surfaces of the frame.




In yet another embodiment of the assembly the phone cover is turned inside surface out and extends over a support portion of the frame that defines the passageway as a through opening in the frame with an end portion of the phone cover extending across the through opening. When a phone such as an ear bud is pressed against that end portion of the phone cover and moved through the through opening in the frame, the phone cover will be turned outer surface out and its inner surface will extend around the phone to position the phone in the socket in the phone cover.

DETAILED DESCRIPTION OF THE INVENTION




Referring now to

FIGS. 1 through 3

of the drawing, there is illustrated a first embodiment of an assembly according to the present invention generally designated by the reference numeral


10


. The assembly


10


includes a phone cover


11


of thin, flexible, resiliently stretchable material defining a socket


12


having an inlet opening


13


. The phone cover


11


is particularly adapted to closely receive a bulbous ear phone


14


of the type called an ear bud that is inserted into the socket


12


through the inlet opening


13


. The assembly


10


is adapted to facilitate easy insertion of the ear bud


14


into the socket


12


in the phone cover


11


by including a frame


16


of stiff material (e.g., 24 point (0.024 inch or 0.06 cm thick) polyethylene coated cardboard or a stiff polymeric film such as a 0.02 inch or 0.05 cm thick polyethylene or polypropylene) having a passageway in the form of a through opening


17


extending between opposite major surfaces of the frame


16


, and a support layer


18


of thin flexible material attached to the phone cover


11


along and around the inlet opening


13


and extending outwardly from the phone cover


11


to a portion of the frame


16


defining the through opening


17


. The support layer


18


is attached to the frame


16


(e.g., by a heat seal between the support layer


18


and the frame


16


or by a suitable adhesive or mechanical attachment) with the inlet opening


13


of the phone cover


11


generally aligned and concentric with the through opening


17


in the frame


16


. The frame


16


is adapted to have the ear bud


14


inserted into the socket


12


through the through opening


17


and the inlet opening


13


in the phone cover


11


as indicated in

FIG. 3

; and the assembly


10


includes means in the form of a line


19


of weakness (e.g., perforations) for affording separation of the cover


11


around the ear bud


14


from the support layer


18


and the frame


16


. Also, the frame


16


and the support layer


18


include means in the form of lines


20


of weakness (e.g., perforations and slits) leading to the edges of a projecting tab like portion of the frame


16


that facilitates breaking the frame


16


and support layer


18


into parts to remove them from around the ear bud


14


within the phone cover


11


.




The ear bud


14


can thus be covered with the phone cover


11


by supporting the frame


16


either manually or otherwise while manually inserting the ear bud


14


into the socket


12


through the through opening


17


and the inlet opening


13


in the phone cover


1


as is indicated by the arrow in

FIG. 3

; and then separating the cover


11


around the ear bud


14


from the support layer


18


and the frame


16


at the line


19


of weakness. The support layer


18


and frame


16


can then be broken apart along at least one of the lines


20


of weakness to facilitate removing them from around the ear bud


14


covered by the phone cover


11


.




As is best seen in

FIGS. 2 and 3

, the phone cover


11


in the assembly


10


includes an outer part


21


having a generally circular periphery


22


, and an adjacent washer-like part


23


having a circular outer periphery attached or bonded to the periphery


22


of the outer part


21


and having a concentric circular inner edge portion


24


defining a through opening and being attached or bonded to the support layer


18


. The frame


16


has opposite major surfaces or sides, with the support layer


18


being attached to the frame


16


along one side. The support layer


18


and/or the washer-like part


23


extend through the opening


17


in the frame


16


, and the outer part


21


of the phone cover


11


is positioned on the side of the frame


16


opposite that to which the support layer


18


is attached. As illustrated, the washer-like part


23


of the phone cover


11


has the line


19


of weakness adjacent its inner edge portion to provide the means affording separation of the phone cover


11


from the support layer


18


and the frame


16


, however, that means could alternatively be afforded by a line of weakness in the support layer


18


, or a separable attachment between the support layer


18


and the washer-like part


23


.




The through opening


17


in the frame


16


is smaller in diameter than the outer part


21


of the phone cover


11


, and the frame


16


has slits


25


extending radially from the though opening


17


forming cantilevered portions of the frame


16


around the through opening


17


that are flexible and/or bendable at a line of perforations


26


encircling their proximal ends to afford movement of the ear bud


14


through the through opening


17


and into the socket


12


in the phone cover


11


.




The phone cover


11


is adapted to be positioned around the ear bud


14


with its outer part


21


extending across the speaker in the ear bud


14


. Thus the outer part


21


should be of a thin, flexible, resiliently stretchable material that is also quite sound transmissive (e.g., of 110 PPI (pores per inch) porous filter foam commercially available from Foamex, Eddystone, Pa., or of a nylon mesh). The washer-like part


23


of the phone cover


11


is intended to extend around portions of the ear bud


14


surrounding its speaker and thus can be made of a thin flexible resiliently stretchable material that may or may not be as sound transmissive as the outer part


21


, and which may be more slippery than the outer part


21


and to facilitate insertion of the ear bud


14


(e.g., a nylon film or mesh which is inherently slippery, or material like the 110 PPI filter foam or a urethane film which, optionally, may be coated with a slipping agent such as talc). The support layer


18


is not part of the phone cover


11


and thus can be made of a thin flexible material that may or may not be as resiliently stretchable as the outer part


21


or the washer-like part


23


, or as sound transmissive as the outer part


21


and may also be more slippery than the outer part


21


to facilitate insertion of the ear bud


14


(e.g., a nylon film or mesh which is inherently slippery, or material like the 110 PPI filter foam or a urethane film which, optionally, may be coated with a slipping agent such as talc).




Generally, a method for forming the assembly


10


comprises the steps of (1) providing the frame


16


with its through opening


17


; (2) constructing the phone cover


11


; (3) attaching the support layer


18


to the phone cover


11


along and around its inlet opening


13


and to the portion of the frame


16


defining the through opening


17


with the inlet opening


13


to the phone cover


11


generally aligned and concentric with the through opening


17


in the frame


16


; and (4) causing the line


19


of weakness that affords separation of the phone cover


11


from the support layer


18


and the frame


16


. The phone cover


11


can be constructed and the support layer


18


can be attached by the steps sequentially and schematically illustrated from left to night in

FIGS. 4



a


,


4




b


,


4




c


, and


4




d


of (1) attaching a piece


27


of the thin flexible material from which the support layer


18


is to be formed to one side or major surface of the frame


16


with that piece


27


of material extending across the through opening


17


in the frame


16


(

FIG. 4



a


); (2) positioning a piece


28


of the thin flexible resiliently stretchable material from which the washer-like part


23


is to be made along the opposite side or major surface of the frame


16


and over the through opening


17


in the frame


16


(

FIG. 4



b


); (3) forming the through opening defined by the inner edge portion


24


of the washer-like part


23


and a corresponding through opening in the support layer


18


in portions of the pieces


27


and


28


of materials extending across the through opening


17


in the frame


16


(

FIG. 4



b


); (4) attaching or bonding the pieces


27


and


28


of materials to each other along and around the through openings formed by the step of forming the through opening defined by the inner edge portion


24


(

FIG. 4



b


)(i.e., such forming and attachment steps (3) and (4) can be performed simultaneously by use of a heated die or punch if the flexible materials are appropriate thermoplastics ); (5) positioning a piece


29


of the thin, flexible, resiliently stretchable, sound transmissive material from which the outer part


21


is to be made along the surface opposite the frame


16


of the piece


28


of material from which the washer-like part


23


is to be made after the steps of forming the through openings and attaching the pieces


27


and


28


of materials to each other along and around the through openings (

FIG. 4



c


); (6) forming against the cantilevered portions of the frame


16


the circular periphery


22


of the outer part


21


and the outer periphery of the washer-like part


23


in the pieces


28


and


29


of materials from which the outer and the washer-like parts


21


and


23


are to be made (

FIG. 4



c


); (7) attaching or bonding the pieces


28


and


29


of materials to each other along and around the circular and outer peripheries


22


formed by the step of forming against the cantilevered portions of the frame


16


(

FIG. 4



c


) (i.e., such forming and attachment steps (6) and (7) can be performed simultaneously by use of a heated die or punch if the flexible materials are both appropriate thermoplastics); and (


9


) removing the parts of the pieces


27


,


28


, and


29


of materials not needed for making the assembly


10


(

FIG. 4



d


).




By reviewing

FIGS. 4



a


,


4




b


,


4




c


, and


4




d


it can be seen that a multiplicity of the frames


16


can be provided along a strip of material from which the frames


16


are made and moved along a path, the pieces


27


,


28


and


29


of materials from which the support layers


18


, the outer parts


21


and the washer-like parts


23


are made can be supplied in strips guided to positions on the path along which the strip of frames


16


is moved, and the steps for forming the assemblies


10


can be performed sequentially along the frames


16


in the strip moved along that path generally in the sequence described above to form a concatenation of the assemblies


10


including phone covers


11


.




Referring now to

FIGS. 5 and 6

of the drawing, there is illustrated a second embodiment of an assembly according to the present invention generally designated by the reference numeral


30


. The assembly


30


includes a phone cover


11


a and a support layer


18




a


that have essentially the same structures as the phone cover


11


and support layer


18


described above, and have their structural elements identified with the same reference numerals used above with respect to the assembly


10


except for the addition of the suffix “a”. The phone cover


11




a


is of thin, flexible, resiliently stretchable material, defines the socket


12




a


having an inlet opening


13




a


that is adapted to closely receive the bulbous car phone or ear bud


14


, and the support layer


18




a


is of thin flexible material and is attached to the phone cover


11




a


along and around its inlet opening


13




a


and extends outwardly from the phone cover


11




a


to a frame


36


; the support layer


18




a


being attached to the frame


36


with the inlet opening


13




a


of the phone cover


11




a


generally concentric with a through circular opening


37


in the frame


36


. The assembly


30


primarily differs from the assembly


10


in that the opening


37


in the frame


36


is larger in diameter than the outer part


21




a


of the phone cover


11


which can facilitate inserting the ear bud


14


into the phone cover


11




a


. The support layer


18




a


and the frame


36


can have lines of weakness


20




a


and


40


respectively that allow them to be separated into parts to remove them from around the ear bud


14


within the phone cover


11




a


. The attachments between the support layer


18




a


and the washer-like part


23




a


and between the washer-like part


23




a


and the outer part


21


a can be made with an adhesive or by ultrasonic or thermal welding. If ultrasonic or thermal welding is used, the support layer


18




a


and the washer-like part


23


can be attached together first, and a thermally protecting layer can then be temporarily provided between the support layer


18




a


and the washer-like part


23




a


as the outer part


21




a


is attached to the washer-like part


23




a.






Referring now to

FIGS. 7 and 8

of the drawing, there is illustrated a third embodiment of an assembly according to the present invention generally designated by reference numeral


60


. The assembly


60


includes a generally flattened phone cover


61


of thin flexible resiliently stretchable material defining a socket


62


having an inlet opening


63


. The phone cover


61


is particularly adapted to closely receive a bulbous car phone


64


of the type called an ear bud that is inserted into the socket


62


through the inlet opening


63


. The assembly


60


is adapted to facilitate easy insertion of the ear bud


64


into the socket


62


in the phone cover


61


by further including a frame


66


of stiff material (e.g.,


24


point (0.024 inch or 0.06 cm thick) polyethylene coated cardboard or a stiff film such as a 0.02 inch or 0.05 cm thick polyethylene or polypropylene) having a circular through opening


67


, and a support layer


68


of thin flexible material attached to the phone cover


61


along and around the inlet opening


63


and extending outwardly from the phone cover


61


to the frame


66


. The support layer


68


is attached to the frame


66


with the inlet opening


63


of the phone cover


61


generally aligned and concentric with the through opening


67


in the frame


66


. The frame


66


is adapted to have the ear bud


64


inserted into the socket


62


through the inlet opening


63


in the phone cover


61


and the opening


67


in the frame


66


; and the assembly


60


includes means in the form of a line


69


of weakness (e.g., perforations) for affording separation of the phone cover


61


from the support layer


68


. Also, the frame


66


and the support layer


68


include means in the form of lines


70


of weakness (e.g., perforations or slits) facilitating breaking apart the frame


66


and support layer


68


to facilitate removing them from around the ear bud


64


after it is positioned in the phone cover


61


.




The phone cover


61


is thus applied to the ear bud


64


by supporting the frame


66


either manually or otherwise while manually inserting the ear bud


64


into the socket


62


through the inlet opening


63


in the phone cover


61


and the opening


67


in the frame


66


; and then separating the cover


61


around the ear bud


64


from the support layer


68


and the frame


66


at the line


69


of weakness. The support layer


68


and frame


66


can then be separated into parts along some of its lines


70


of weakness to facilitate removing them from around the ear bud


64


within the phone cover


61


.




As is best seen in

FIG. 9

, the phone cover


61


and the support layer


68


are defined by two pieces of sheet material each including a portion


72


that is generally bulbous shaped about a central axis


73


and has a base with opposite sides. The pieces of sheet material each also include a support portion


74


with edges


75


extending in opposite directions away from opposite sides of the base of the bulbous portion


72


generally at right angles to the axis


73


. The edges


75


of the support portions


74


and the peripheries of the bulbous portions


72


are bonded together. The two support portions


74


of the pieces of sheet material are positioned so that they are generally coplanar to form the support layer


68


, and are attached along one major surface of the portion of the frame


66


defining the through opening


67


as is seen in

FIGS. 7 and 8

. The bulbous portions


72


of the pieces of sheet material that form the phone cover


51


then project with their axes


73


generally at a right angle to the generally coplanar support portions


74


through the through opening


67


and away from the side of the frame


66


opposite that to which the support portions


74


are attached. The two pieces of sheet material each have one half of the line


69


of weakness between its bulbous portion


72


and its support portion


74


to provide the means affording separation of the phone cover


61


from the support layer


68


and the frame


66


.




As can be seen from

FIG. 9

, the phone cover


61


can be constructed by (1) providing the two pieces of sheet material that each include the portion


72


that is generally bulbous shaped about the central axis


73


and has a base with opposite sides, and the support portions


74


with edges


75


extending in opposite directions away from opposite sides of the base of the bulbous portion


72


generally at right angles to the axis


73


; (2) bonding together the edges


75


of the support portions


74


and the peripheries of the bulbous portions


72


, the bonded bulbous portions


72


forming the phone cover


61


and the bonded Support portions


74


forming the support layer


68


; and (3) attaching the support portions


74


or support layer


68


to the frame


66


as shown in

FIGS. 7 and 8

with the bonded bulbous portions


72


generally aligned and concentric with the through opening


67


in the frame


66


. The method can also include providing the lines


70


of weakness in the support layer


68


and in the frame


66


to afford manually separating the support layer


68


and the frame


66


into parts to facilitate removal of the ear bud


64


covered by the phone cover


61


from the support layer


68


and the frame


66


.




The phone cover


61


can be positioned around the ear bud


64


with one of the portions


72


extending across the speaker in the ear bud


64


and the other of the portions


72


extending around the side of the car bud


64


opposite its speaker. At least the portion


72


intended to extend across the speaker in the ear bud


64


should be of a thin, flexible, resiliently stretchable material that is also quite sound transmissive (e.g., of 110 PPI porous filter foam or of a nylon mesh). The other portion


72


that is not intended to extend across the speaker in the ear bud


64


can be made of a thin flexible resiliently stretchable material that is not as sound transmissive as the portion


72


intended to extend across the speaker and may be more slippery than the portion


72


intended to extend across the speaker in the ear bud


64


to facilitate insertion of the ear bud


14


(e.g., a nylon film or mesh which is inherently slippery, or material like a urethane film which, with the portion


72


intended to extend across the speaker, may optionally be coated with a slipping agent such as talc). Alternatively that other portion


72


can be made of the same thin, flexible, resiliently stretchable sound transmissive material as the portion


72


intended to extend across the speaker (both portions optionally being coated with the slipping agent) which provides the advantage of not requiring a specific orientation of the phone cover


61


on the ear bud


64


.




Referring now to

FIGS. 10 and 11

of the drawing, there is illustrated a fourth embodiment of an assembly according to the present invention generally designated by the reference numeral

82


in the phone cover


81


by including a frame


86


and a support layer


88


between the phone cover


81


and the frame


86


. The frame


86


is formed from first and second laminated layers


84


and


85


of stiff material (e.g., 24 point (0.024 inch or 0.06 cm thick) polyethylene coated cardboard or a stiff polymeric film such as a 0.02 inch or 0.05 cm thick polyethylene or polypropylene). The first layer


84


has a U-shaped slot opening through one edge that, with an arcuate depression


79


in the second layer


85


projecting away from the first layer


84


, defines a passageway

inserted into the socket


82


by positioning it in the opening


97


, pressing it into the depression


79


to open the end of the flatted tube formed by the support layer


88


, and then moving it along the inner surface of the tube formed by the support layer


88


into the inlet opening


83


in the phone cover


81


. The assembly


80


includes a line


90


of weakness (e.g., perforations) extending along the support layer


88


that allow it to rupture as the ear bud


64


moves along its inner surface toward the phone cover


81


, and also includes a line


89


of weakness (e.g., perforations) between the phone cover


81


and the support layer


88


for affording separation of the phone cover


81


from the support layer


88


after the ear bud


64


is positioned in the phone cover


81


.




The phone cover


81


and the support layer


88


are defined by two pieces of sheet material each including a portion


92


that is generally bulbous shaped about a central axis


93


and has a base with opposite sides, and a support portion


94


with edges


95


extending away from the base of the bulbous portion


92


. The peripheries


91


of the bulbous portions


92


are bonded together (e.g., by heat bonding) except along their bases that form the inlet opening


83


. The support portions


94


of the pieces of sheet material are positioned so that their major surfaces are generally parallel with those of the frame


86


and have their edges


95


attached together and between the layers


84


and


85


forming the frame


86


so that the two support portions


94


form the support layer


88


. The bulbous portions


92


of the pieces of sheet material that form the phone cover


81


then project with their axes


93


generally parallel to the major surfaces of the frame


86


. The outer support portion


94


has the opening


97


adapted to receive the ear bud


64

85


of the frame extends across all portions of the U-shaped slot in the first layer


84


. Optionally, the second layer


85


could have an opening in place of the depression


79


to facilitate inserting the ear bud


64


into the opening


97


, and/or could have an opening adjacent the cover


81


which could facilitate movement of the ear bud into the phone cover


81


. Also, the second layer


85


could have a U-shaped slot aligned with and corresponding in size and shape to the U-shaped slot in the first layer


84


, or the first layer


84


could be eliminated, and the edges


95

94


could be attached only to the first layer


84


.




The car bud


64


can be covered with the phone cover


81


by supporting the frame


86


either manually or otherwise, positioning the ear bud


64


in the opening


97


and pressing it into the depression


79


to separate the support portions


94


, and then moving the ear bud


64


between the support portions


94


toward the inlet opening


83


to the phone cover


81


while rupturing the support layer


88


along the line


90


of weakness as the ear bud


64


moves along its inner surface, whereupon the ear bud


64


will be directed by the inner surface of the separating tube-like support layer


88


through the inlet opening


83


into the socket


82


in the phone cover


81


. The phone cover


81


can then be separated from the support layer


88


at the line


89


of weakness.




The assembly


80


can be constructed by providing the two pieces of material each including the portion


92


that is generally bulbous shaped about the central axis


93


and has a base with opposite sides and the support portion


94


with edges


95


extending away from opposite sides of the base of the bulbous portion


92


; (2) bonding together the peripheries of the bulbous portions


92


to form the phone cover


81


and the peripheries of the support portions


94


to form the support layer


88


, and (3) attaching together the two layers


84


and


85


defining the frame


86


with the edges


95


of the support portion


94


attached between them and to the portions of the frame


86


defining the passageway


87


and with the bonded bulbous portions


92


generally aligned with the passageway


87


in the frame


86


.




The phone cover


81


can be positioned around the ear bud


64


with one of the portions


92


extending across the speaker in the ear bud


64


and the other of the portions


92


extending around the side of the ear bud


64


opposite its speaker. At least the portion


92


intended to extend across the speaker in the ear bud


64


should be of a thin, flexible, resiliently stretchable material that is also quite sound transmissive (e.g., of 110 PPI porous filter foam or of nylon mesh). The other portion


92


that is not intended to extend across the speaker in the ear bud


64


can be made of a thin flexible resiliently stretchable material that is not as sound transmissive as the portion


92


intended to extend across the speaker and may be more slippery than the portion


92


intended extending across the speaker in the ear bud


64


to facilitate insertion of the ear bud


64


(e.g., a nylon film or mesh which is inherently slippery, or material like a urethane film which, with the portion


92


intended to extend across the speaker, may optionally be coated with a slipping agent such as talc). Alternatively that other portion


92


can be made of the same thin, flexible, resiliently stretchable sound transmissive material as the portion


92


intended to extend across the speaker (and, optionally, with the portion


92


intended to extend across the speaker, can be coated with that slipping agent) which provides the advantage of not requiring a specific orientation of the phone cover


81


on the ear bud


64
