Patent ID: 8908897

Claim:
A method for constructing an acoustic waveguide for a headset boom comprising: forming a first acoustic waveguide component of the headset boom comprising a first outer surface and a first inner surface, wherein the first inner surface comprises a first groove and a second groove; forming a second acoustic waveguide component of the headset boom comprising a second outer surface and a second inner surface, wherein the second inner surface comprises a third groove and a fourth groove; and bonding the first acoustic waveguide component and the second acoustic waveguide component together so that the first groove and the third groove are arranged to form a first acoustic channel and the second groove and the fourth groove are arranged to form a second acoustic channel, wherein the first acoustic channel comprises a first end terminating in an aperture and a second end terminating in a first port configured to receive acoustic waves associated with user speech, and the second acoustic channel comprises a third end terminating in a second aperture and a fourth end terminating in a second port configured to receive acoustic waves associated with user speech, and wherein the first port and the second port are separated by an offset distance and the first acoustic channel comprises a meander arranged so that the first acoustic channel and the second acoustic channel have a same path length.
