DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference is now made to Fig. 1 which illustrates a cellular telephone 10, constructed and operative in accordance with a preferred embodiment of the present invention.
Cellular telephone 10 preferably includes a body 12, a telephone transmitter 14 and receiver 16 disposed within body 12, and a mouthpiece 18 and an earpiece 20 coupled to transmitter 14 and receiver 16.
Cellular telephone 10 also includes a collapsible sound conduit 30 associated with earpiece 20. Collapsible sound conduit 30 may be integrally formed with body 12 of cellular telephone 10 (described hereinbelow with reference to Fig. 5), or alternatively may be manufactured as a separate unit attachable to telephone 10 (described hereinbelow with reference to Figs. 3, 4A and 4B). In another alternative embodiment, collapsible sound conduit 30 may be integrally formed with a carrying case (not shown in Fig. 1) used with telephone 10 (described hereinbelow with reference to Fig. 6).
Fig. 1 illustrates telephone 10 in a non-operative mode. It is seen that collapsible sound conduit 30 is preferably in a collapsed state when not in use.
Reference is now made to Fig. 2 which illustrates telephone 10 in an operative mode. It is seen that collapsible sound conduit 30 is preferably in an extended state when in use, which enables a user 32 to space earpiece 20 from his/her head while nevertheless maintaining an acceptable level of hearing. Telephone 10 is both spaced from an ear 34 of user 32 by a distance 36 and angled with respect to the head of user 32 by an angle 38, thereby reducing the amount of radiation impinging on the head of user 32 during use.
Reference is now made to Fig. 3 which illustrates a cellular telephone 40 and a collapsible sound conduit 42 bondable thereto, constructed and operative in accordance with a preferred embodiment of the present invention. Collapsible sound conduit 42 may be bonded to an earpiece 44 of telephone 40 by bonding with an adhesive. Alternatively, collapsible sound conduit 42 may be provided with an adhesive pad 46 for bonding to earpiece 44.

Resilient portion 82 may be made of any elastomeric material, such as rubber or neoprene, for example, with a suitable durometer so that collapsible sound conduit 80 has sufficient stiffness or hardness when fully extended. Stiffeners or a stiffening material (not shown) may be integrally molded in the elastomeric material of resilient portion 82 to achieve the required stiffness or hardness. Resilient portion 82 may include recesses 84 that increase the foldability of collapsible sound conduit 80.
Collapsible sound conduit 80 may include a plurality of stiffeners 86 protruding from a user listening portion 88 and/or a plurality of stiffeners 90 protruding from a telephone attachment portion 92. Stiffeners 86 and 90 are preferably shaped as ribs which either protrude perpendicularly or at any other suitable angle. Stiffeners 86 and 90 preferably define an acoustical path 94 from an aperture 96 formed on telephone attachment portion 92 to an aperture 98 formed on user listening portion 88. Stiffeners 86 and 90 are adapted to limit collapsing of collapsible sound conduit 80.
Telephone attachment portion 92 may comprise a bonding pad 99 for attachment to a telephone.
Reference is now made to Figs. 8A, 8B and 8C which illustrate a bellows type collapsible sound conduit 100, constructed and operative in accordance with a preferred embodiment of the present invention. Collapsible sound conduit 100 preferably includes a bellows 102 made of a resilient material, a user listening portion 104 and a telephone attachment portion 106. Collapsible sound conduit 100 also preferably includes a clasp 108 which includes a male fastener 110 and a female fastener 112. Male fastener 110 preferably includes a rounded pivot 114.
In Fig. 8A, collapsible sound conduit 100 is fully extended. In Fig. 8B, it is collapsed. In Fig. 8C, it is seen that user listening portion 104 may pivot about pivot 114, thereby possibly conforming with the motions of a user or the contour of his/her face.
In accordance with another preferred embodiment of the present invention, the collapsible sound conduit may collapse by means of telescoping sections. Examples of such embodiments are describe with reference to Figs. 9A - 14B.

Collapsible sound conduit 150 preferably includes a plurality of telescoping sections 152 and a biasing device, such as a spring 154 for providing tension in the extended state. A catch (not shown) may be provided for holding spring 154 in the collapsed state.
Reference is now made to Figs. 13A and 13B which illustrate a collapsible sound conduit 160, constructed and operative in accordance with a further preferred embodiment of the present invention, in respective extended and collapsed states. Collapsible sound conduit 160 preferably includes a plurality of telescoping sections 162 interconnected to each other, a user listening portion 164 and a telephone attachment portion 166.
Collapsible sound conduit 160 may include a plurality of stiffeners 167 protruding from user listening portion 164 and/or a plurality of stiffeners 168 protruding from telephone attachment portion 166. Stiffeners 167 and 168 are preferably shaped as ribs which either protrude perpendicularly or at any other suitable angle. Stiffeners 167 and 168 preferably define an acoustical path 169 from an aperture 170 formed on telephone attachment portion 166 to an aperture 172 formed on user listening portion 164. Stiffeners 167 and 168 are adapted to limit collapsing of collapsible sound conduit 160.
Reference is now made to Figs. 14A and 14B which illustrate a collapsible sound conduit 174, constructed and operative in accordance with a further preferred embodiment of the present invention. Collapsible sound conduit 174 is substantially identical to collapsible sound conduit 160, with like elements being designated by like numerals. Collapsible sound conduit 174, unlike collapsible sound conduit 160, is provided with one or more additional sets of telescoping sections 162, and stiffener 167 has been eliminated.
Reference is now made to Figs. 15A and 15B which illustrate a collapsible sound conduit 180, constructed and operative in accordance with another preferred embodiment of the present invention, in respective extended and collapsed states. Collapsible sound conduit 180 preferably includes a user listening portion 182 with an aperture 184 formed thereon. User listening portion 184 is preferably pivotally attached to a telephone attachment portion 186 at a pivot 187. Telephone attachment portion 186 preferably has an aperture 188 formed thereon. A bonding pad 190 may be attached to telephone attachment portion 186 for bonding collapsible sound conduit 180 to a cellular telephone (not shown).
In the extended state shown in Fig. 15A, collapsible sound conduit 180 is pivotable to be substantially perpendicular to a telephone (not shown). In the collapsed state shown in Fig. 15B, collapsible sound conduit 180 is pivotable to be substantially parallel with the telephone.
