Patent ID: 7466838

Claim:
An electroacoustic device having at least one transducer assembly comprising: a generally planar baffle plate having inner cavity and outer cavity surfaces, and a microphone recess for positioning a microphone adjacent to the baffle plate surface; a speaker having a speaker diaphragm for converting input electrical signals into sound waves, wherein the speaker is positioned facing the outer cavity baffle plate surface; a microphone having a microphone diaphragm for converting sound waves into electrical signals, wherein the microphone is positioned adjacent to the baffle plate, the microphone faces generally the baffle plate surface, optional microphone acoustic foam overlays the microphone face and is positioned generally between the microphone face and the baffle plate surface, and the speaker diaphragm and the microphone diaphragm are positioned in substantially a common acoustic plane; and a circuit operably connected to the speaker and the microphone for modifying the electrical signals from the microphone and transmitting the electrical signals to the speaker.
