Abstract
The present invention is directed to a mobile device with improved acoustic porting. The mobile device includes a housing (302) that has at least one sound hole, a transducer (304) for converting an electrical signal into an acoustical signal, and a grommet (306) that engages the housing and the transducer to form an interior cavity (314). A passage (312) 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.
