Abstract: A speaker assembly including a first speaker comprising a first diaphragm and a first voice coil movably coupled to a first magnet assembly, wherein the first diaphragm faces a first direction, the first voice coil moves along a first axis in the first direction when driven by an audio signal and the first magnet assembly is coupled to a fixed structure by a first compliant mounting member; and a second speaker laterally offset from the first speaker and including a second diaphragm and a second voice coil movably coupled to a second magnet assembly, wherein the second diaphragm faces a second direction different from the first direction, the second voice coil moves along a second axis in the second direction when driven by an audio signal and the second magnet assembly is coupled to the fixed structure by a second compliant mounting member.

Abstract: An audio appliance includes a microphone transducer having an acoustically sensitive region to convert incident acoustic energy to a corresponding output signal and a barometric transducer having a pressure-responsive region to convert an ambient pressure to a corresponding output signal. The audio appliance also has an acoustic housing defining a chamber to fluidly couple the microphone transducer with the barometric transducer, together with a processor and a memory containing instructions. The instructions, when executed by the processor, cause the audio appliance to determine a presence or an absence of an ambient impairment to the microphone transducer based at least in part on the output signal from the barometric transducer. Responsive to a determined presence of an ambient impairment to the microphone transducer, the instructions, when executed by the processor, cause the audio appliance to mitigate effects of the ambient impairment.
