Flexible acoustic coupler

Claim 2

An acoustic coupler comprising: a first half member housing a speaker therewithin; a second half member housing a microphone therewithin; a flexible hinge means coupling said first half member to said second half member, said flexible hinge means having at least three substantially parallel predefined hinge axes, said flexible hinge means being a means for enabling the position and orientation of said first half member to be independently varied with respect to said second half member through a predetermined range of relative spatial positions and angular orientations with good flexibility with respect to the degrees of freedom required to mate said acoustic coupler with substantially all telephone handsets while providing substantial resistance to relative motion unnecessary to such proper mating and tending to make the use of said acoustic coupler inconvenient and cumbersome.

Claim 3

An acoustic coupler comprising: a first half member housing a speaker therewithin; a second half member housing a microphone therewithin; a flexible hinge means coupling said first half member to said second half member, said flexible hinge means comprising: a flexible sheet of material; a first hinge panel mounted upon said sheet; a second hinge panel mounted upon said sheet being secured to said first half member; a first portion of said flexible sheet being secured to said first half member; a second portion of said flexible sheet being secured to said second half member; said first and second hinge panels being secured on said sheet between said first and second portions to form three hinge joints; whereby the position and orientation of said first half member may be varied with respect to said second half member and whereby flexing of said joints may vary the distance between, and the angular orientation of, said first and second half members.

Claim 4

An acoustic coupler comprising: a first half member housing a speaker therewithin; a second half member housing a microphone therewithin; a flexible hinge means coupling said first half member to said second half member, said flexible hinge means comprising: a flexible sheet of material; a first hinge panel mounted upon said sheet; a second hinge panel mounted upon said sheet being secured to said first half member; a first portion of said flexible sheet being secured to said first half member; a second portion of said flexible sheet being secured to said second half member; said first and second hinge panels being secured on said sheet between said first and second portions to form three hinge joints; whereby the position and orientation of said first half member may be varied with respect to said second half member and whereby flexing of said joints may vary the distance between, and the angular orientation of, said first and second half members.

Claim 5

The acoustic coupler according to claim 2 further provided with a means for securing a telephone handset to said acoustic coupler, said means for securing comprising: a pair of straps, one end of each of said pair of straps being secured to a respective one of said half members; the other end of each of said pair of straps being provided with means for releasably securing said other end to said respective half-member.

Claim 6

The acoustic coupler according to claim 3 wherein said means for releasably securing comprises cooperatively disposed hook and eye members for effecting interlock on contact and non-destructive detachment using moderate force.

Claim 7

The acoustic coupler according to claim 3 wherein said flexible sheet material is polyster film.

Claim 8

The acoustic coupler according to claim 2 wherein said flexible hinge means is provided with conductive means thereon for effecting electrical connections between said first half member and said second half member so that said conductive means may be flexed in conjunction with said flexible hinge.

Claim 9

An acoustic coupler comprising: a first half member housing a speaker therewithin; a second half member housing a microphone therewithin; means for securing a telephone handset upon said first and second half members with the mouthpiece of said handset proximate said microphone; a flexible hinge means coupling said first half member to said second half member, said flexible hinge means comprising: a flexible sheet of material; a first portion of said flexible sheet being secured to said first half member; a second portion of said flexible sheet being secured to said second half member; a first hinge panel mounted upon said sheet; a second hinge panel mounted upon said sheet in spaced apart relation with said first hinge panel; said first and second hinge panels being secured on said sheet between said first and second portions to form three hinge joints; whereby flexing of said joints will vary the distance between, and the angular orientation of said first and second half members.

Claim 10

An acoustic coupler comprising: a first half member housing a speaker therewithin; a second half member housing a microphone therewithin; means for securing a telephone handset upon said first and second half members with the mouthpiece of said handset proximate said microphone; a flexible hinge means coupling said first half member to said second half member, said flexible hinge means comprising: a flexible sheet of material; a first portion of said flexible sheet being secured to said first half member; a second portion of said flexible sheet being secured to said second half member; a first hinge panel mounted upon said sheet; a second hinge panel mounted upon said sheet in spaced apart relation with said first hinge panel; said first and second hinge panels being secured on said sheet between said first and second portions to form three hinge joints; whereby flexing of said joints will vary the distance between, and the angular orientation of said first and second half members.

Claim 11

The acoustic coupler according to claim 7 wherein said flexible sheet of material is polyester film.

Claim 12

The acoustic coupler according to claim 7 wherein said flexible sheet of material is provided with conductive means as an integral part thereof for effecting electrical connections between said first half member and said second half member.

Claim 13

The acoustic coupler according to claim 7 further provided with a means for securing a telephone handset to said acoustic coupler.

Claim 14

An acoustic coupler comprising: a first assembly housing a speaker therewithin; a second assembly housing a microphone therewithin; means for securing a telephone handset upon said first and second assemblies with the mouth piece of said handset proximate said speaker and the earpiece of said handset proximate said microphone; flexible means coupling said first assembly to said second assembly, said flexible means comprising: a flexible sheet of material; a first hinge panel mounted upon said sheet; a second hinge panel mounted upon said sheet in spaced apart relation with said first hinge panel; a first portion of said flexible sheet being secured to said first assembly; a second portion of said flexible sheet being secured to said second assembly; said first and second hinge panels being secured on said sheet between said first and second portions to form three hinge joints; whereby the position and orientation of said first and second assemblies may be varied to correspond to the position and orientation of said mouthpiece and said earpiece respectively.

Claim 15

An acoustic coupler comprising: a first assembly housing a speaker therewithin; a second assembly housing a microphone therewithin; means for securing a telephone handset upon said first and second assemblies with the mouth piece of said handset proximate said speaker and the earpiece of said handset proximate said microphone; flexible means coupling said first assembly to said second assembly, said flexible means comprising: a flexible sheet of material; a first hinge panel mounted upon said sheet; a second hinge panel mounted upon said sheet in spaced apart relation with said first hinge panel; a first portion of said flexible sheet being secured to said first assembly; a second portion of said flexible sheet being secured to said second assembly; said first and second hinge panels being secured on said sheet between said first and second portions to form three hinge joints; whereby the position and orientation of said first and second assemblies may be varied to correspond to the position and orientation of said mouthpiece and said earpiece respectively.
