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.
