Patent ID: 7983433

Claim:
An earset assembly, comprising: a housing having a microphone port and a speaker port that are located in physical communication with an ear canal of a user when the earset assembly is retained by an ear of the user; a microphone enclosed by the housing and having first and second input ports, the first input port acoustically coupled to the microphone port by a first tube so that sound waves present at the microphone port of the housing are communicated to the first input port of the microphone via the first tube so that the microphone detects air pressure changes occurring in the ear canal of the user, wherein the first tube is enclosed by the housing and wherein the coupling of the first input port of the microphone to the microphone port of the housing is closed to an environment surrounding the user; and a speaker enclosed by the housing and having an output port acoustically coupled to the speaker port by a second tube that is enclosed by the housing to broadcast sounds to the ear canal of the user and the output port acoustically coupled to the second input port of the microphone by a third tube that is enclosed by the housing, is separate from the first tube, and is acoustically joined with the second tube so that the microphone cancels at least a portion of feedback from the sounds broadcast by the speaker and detected at the first input port of the microphone by travel through the second tube, the ear canal and the first tube.
