1. A personal electronic device comprising:

  • a) a main body; and

    b) an ear flip member coupled to said main body and including a speaker assembly, said speaker assembly comprising;

    (1) a housing including front and rear opposed surfaces spaced apart along a depthwise axis;

    (2) a transducer disposed in said housing between said front and rear surfaces and along each of said depthwise axis, a longitudinal axis extending perpendicular to said depthwise axis, and a transverse axis extending transverse to said longitudinal axis and perpendicular to said depthwise axis; and

    (3) said housing defining a tuned resonator volume therein and in fluid communication with said transducer, at least a portion of said tuned resonator volume being disposed laterally adjacent said trasducer along at least one of said longitudinal and transverse axes;

    (4) wherein said transducer has front and rear opposed sides and said tuned resonator volume comprises;

    a front volume disposed adjacent said transducer between said front side of said transducer and said front surface along said depthwise axis; and

    a side volume contiguous with said front volume and disposed adjacent said transducer along at least one of said longitudinal and transverse axes;

    (5) wherein said personal electronic device further includes a tuned port defined in said housing and fluidly connecting said front surface and said tuned resonator volume; and

    (6) wherein said tuned port is entirely laterally offset from said transducer.
