The DMA also includes a magnet and an electrically-conducting coil. Either the magnet or the coil is mechanically coupled to the member. When the coil is energized, an interaction between a magnetic field of the magnet and a magnetic field from the coil applies a force sufficient to displace the member in the direction perpendicular to the plane. The DMA further includes an electronic control module electrically coupled to the coil and programmed to energize the coil to vibrate the member to produce an audio response from the flat panel.

Abstract: A voice controlled assistant has a housing to hold one or more microphones, one or more speakers, and various computing components. The housing has an elongated cylindrical body extending along a center axis between a base end and a top end.

The speaker(s) are oriented to output sound directionally toward the base end and opposite to the microphone(s) in the top end. The sound may then be redirected in a radial outward direction from the center axis at the base end so that the sound is output symmetric to, and equidistance from, the microphone(s).
