Electro-acoustic headset with ratchet

Claim 2

A headset comprising at least one earpiece having a soundconducting channel therethrough, said earpiece being formed with a projecting portion through which at least a portion of said sound-conducting channel extends, said projecting portion being dimensioned for insertion in the ear canal of the user; a tubular sound conductor coupled at one end to said earpiece in registration with said sound-conducting channel; sound-conducting connector means coupled to the other end of said sound-conducting tube; an electro-acoustic transducer mounted within said earpiece and having an output surface in said earpiece sound-conducting channel; and electrical conductor means coupled to said electroacoustic transducer for applying an audio signal thereto.

Claim 3

A headset as recited in claim 1, wherein said connector means is formed with contact means in the outer wall thereof, said electrical conductor means extending through at least a portion of the sound-conducting channel of said earpiece and through said sound-conducting tube and being connected to said contact means.

Claim 4

A headset as recited in claim 1, wherein said earpiece projecting portion includes a tip portion through which said sound-conducting channel extends, said tip portion being formed of a soft elastic material and being removably mounted on the remaining portion of said projecting portion.

Claim 5

A headset comprising a pair of earpieces, each of said earpieces having sound-conducting channels therethrough; a pair of sound-conducting tubes, one of said earpieces being mounted at the end of each of said sound-conducting tubes with its respective sound-conducting channel in alignment therewith; a pair of sound-conducting connector means, one of said connector means being coupled to the other end of each of said sound-conducting tubes; an electro-acoustic transducer mounted within each of said earpieces, each of said electro-acoustic transducers having its output surface positioned in the respective earpiece sound-conducting channel; electrical conductor means connected to each of said electro-acoustic transducers for applying audio signals to said transducers; and junction means for retaining said pair of sound-conducting tuBes together at a point spaced from said earpieces, said junction means including separate support means for each of said sound-conducting tubes, said separate support means being angularly displaceable relative to each other for the selective adjustment of the spacing between said earpieces, the opposed engaging faces of said support means being provided with meshing teeth, said junction means including resilient clamp means for permitting the incremental relative angular displacement of said support means and the retention of the selected relative angular position of said support means.

Claim 6

A headset comprising a pair of earpieces, each of said earpieces having sound-conducting channels therethrough; a pair of sound-conducting tubes, one of said earpieces being mounted at the end of each of said sound-conducting tubes with its respective sound-conducting channel in alignment therewith; a pair of sound-conducting connector means, one of said connector means being coupled to the other end of each of said sound-conducting tubes; an electro-acoustic transducer mounted within each of said earpieces, each of said electro-acoustic transducers having its output surface positioned in the respective earpiece sound-conducting channel; electrical conductor means connected to each of said electro-acoustic transducers for applying audio signals to said transducers; and junction means for retaining said pair of sound-conducting tuBes together at a point spaced from said earpieces, said junction means including separate support means for each of said sound-conducting tubes, said separate support means being angularly displaceable relative to each other for the selective adjustment of the spacing between said earpieces, the opposed engaging faces of said support means being provided with meshing teeth, said junction means including resilient clamp means for permitting the incremental relative angular displacement of said support means and the retention of the selected relative angular position of said support means.

Claim 7

A headset as recited in claim 4, wherein said pair of connector means are joined together as a unit, and are formed of a nonconducting material, and including contact means formed in the wall of each of said connector means, each of said electrical conductor means being coupled to the contacts in the associated connector means.

Claim 8

A headset as recited in claim 4, wherein said clamp means includes a U-shaped clamp adapted to receive said support means between the arms thereof.

Claim 9

A headset as recited in claim 4, wherein the portions of said pair of sound-conducting tubes between said junction means and said connector means are joined together.

Claim 10

A headset comprising a pair of earpieces, each of said earpieces having sound-conducting channels therethrough; a pair of sound-conducting tubes, one of said earpieces being mounted at the end of each of said sound-conducting tubes, with its respective sound-conducting channel in alignment therewith; a pair of sound-conducting connector means, one of said connector means being mounted at the other end of each of said sound conducting tubes; and a junction means for supporting said pair of sound-conducting tubes together at a point spaced from said earpieces, said junction means including separate support means for supporting each of said sound-conducting tubes, said support means being adapted for relative angular displacement for the selective adjustment of the spacing between said earpieces, the opposed engaging faces of said support means being provided with meshing teeth, said junction means including resilient clamp means for permitting the incremental relative angular displacement of said support means and the retention of the selected relative angular position of said support means.

Claim 11

A headset comprising a pair of earpieces, each of said earpieces having sound-conducting channels therethrough; a pair of sound-conducting tubes, one of said earpieces being mounted at the end of each of said sound-conducting tubes, with its respective sound-conducting channel in alignment therewith; a pair of sound-conducting connector means, one of said connector means being mounted at the other end of each of said sound conducting tubes; and a junction means for supporting said pair of sound-conducting tubes together at a point spaced from said earpieces, said junction means including separate support means for supporting each of said sound-conducting tubes, said support means being adapted for relative angular displacement for the selective adjustment of the spacing between said earpieces, the opposed engaging faces of said support means being provided with meshing teeth, said junction means including resilient clamp means for permitting the incremental relative angular displacement of said support means and the retention of the selected relative angular position of said support means.

Claim 12

A headset as recited in claim 8, wherein said clamp means includes a U-shaped clamp adapted to receive said support means between the arms thereof.

Claim 13

A headset as recited in claim 8, wherein the portions of said pair of sound-conducting tubes between said junction means and said connector means are joined together.
