Abstract

A device for a cellular telephone 10 comprising a collapsible sound conduit 30 associated with the telephone earpiece 20 that has a collapsed or non-extended state when not in use and an extended state when in use. In use the device enables the user's ear to be spaced 36 from the earpiece 20 and angled 38 with respect to the head of the user, thereby reducing the amount of radiation impinging on user's head, while nevertheless maintaining an acceptable level of hearing. The collapsible sound conduit 30 may be of various forms including a conduit with a plurality of telescoping sections (Figures 9-14), a conduit with a resilient portion that is foldable into itself (Figure 7) and a conduit including bellows (Figure 8). One embodiment (Figure 15) shows a pivotable conduit that in its collapsed state lies substantially parallel with the telephone and in its extended state, extends perpendicularly out from the telephone. The device may be integrally formed with, separate from or attached to the telephone and/or a carrying case and various arrangements for such are shown.

The device could be separate from the telephone and also be separate from a carrying case for the telephone, but alternatively the collapsible sound conduit could be attached to either the telephone or the carrying case, for example by bonding thereto, or by at least one fastener provided on the device, or by being integrally formed therewith.
The device may be provided in combination with both the telephone and a carrying case for the telephone.
In a first embodiment, the collapsible sound conduit includes a plurality of telescoping sections. The telescoping sections may be threadable with each other.
Alternatively, or additionally, the telescoping sections may be a plurality of coils.
In a second embodiment, the collapsible sound conduit includes a resilient portion which is collapsible and foldable into itself. The collapsible sound conduit may further include a plurality of stiffeners, and the stiffeners may include ribs which are arranged to define an acoustical path. The stiffeners may be adapted to limit collapsing of the collapsible sound conduit beyond a predetermined position.
In a third embodiment, the collapsible sound conduit includes a bellows. The bellows may have a surface which is tiltable about a pivot.
In a fourth embodiment, the collapsible sound conduit includes a conduit pivotable about a pivot such that, in the collapsed state, the collapsible sound conduit is pivotable to be substantially parallel to the telephone and, in the extended state, the collapsible sound conduit is pivotable to be substantially perpendicular to the telephone.
Further, the collapsible sound conduit may include a plurality of detents for fixing the collapsible sound conduit in the collapsed and extended states.
