Abstract: In one embodiment, a speaker device assembly includes a first voice coil assembly moveable along an axis of a magnetic field of a magnetic core responsive to an induced current to facilitate pressure variations in a medium, and cause recoil vibration on a speaker device assembly structure. The speaker device assembly further includes a second voice coil assembly having a counter balance mass that accounts for at least a mass of the first voice coil assembly, and moveable along the axis of the magnetic field in a direction opposite the first voice coil assembly to attenuate the recoil vibration on the speaker device assembly structure, when the first voice coil assembly moves along the axis of the magnetic field.

Abstract: The disclosed technology relates to a microphone array. The array comprises a plurality of microphones with each microphone having a horn portion. Each microphone of the array further comprises an instrument disposed at a distal end of the horn portion. Each instrument of the array is configured to convert sound waves into an electrical signal. The microphone array further comprises a beamforming signal processing circuit electrically coupled to each instrument and configured to create a plurality of beam signals based on respective electrical signals.
