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
80
. The assembly
80
includes a generally flattened phone cover
81
of thin, flexible, resiliently stretchable material defining a socket
82
having an inlet opening
83
, which phone cover
81
is adapted to closely receive an car bud Such as the car bud
64
(see
FIG. 8
) inserted into the socket
82
through the inlet opening
83
). The assembly
80
is adapted to facilitate easy insertion of the ear bud
64
into the socket
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
87
along, one side of the frame
86
. The support layer
88
is a generally flattened tube of thin flexible material attached to the phone cover
81
along and around the sides of the inlet opening
83
, extending outwardly from the phone cover
81
to edges of the frame
86
defining the passageway
87
, and having an opening
97
along one side at its end opposite the phone cover
81
and over the depression
79
. The support layer
88
is attached between the layers
84
and
85
of the frame
86
with the inlet opening
83
of the phone cover
81
generally aligned with the passageway
87
along the side of frame
86
. The assembly
80
is adapted to have the ear bud
64
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
that is above the depression
79
and spaced along the passageway
87
from the phone cover
81
.
As illustrated, the second layer
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
of the support portion
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
.
