  • Mobile device with improved acoustic porting
    Patent number: 7505602
    Abstract: The present invention is directed to a mobile device with improved acoustic porting. The mobile device includes a housing that has at least one sound hole, a transducer for converting an electrical signal into an acoustical signal, and a grommet that engages the housing and the transducer to form an interior cavity. A passage acoustically couples the interior cavity with the interior of the housing. The transducer emits sound into the interior cavity. The sound travels from the interior cavity through the passage into the interior of the housing and then to the user's ear via the sound hole(s) in the housing. The passage may be any channel, tube, passageway, or pathway that allows an acoustical signal to travel from the interior cavity to the interior of the housing. The transducer may also emit sound into the interior of the housing that mixes with the sound traveling from the interior cavity through the passage into the interior of the housing.
