Voice-controlled electronic device

A voice-controlled electronic device comprising:

• an axisymmetric device housing having a longitudinal axis bisecting opposing top and bottom surfaces and a side surface extending between the top and bottom surfaces;
• a computer-readable memory disposed within the axisymmetric device housing;
• a plurality of microphones disposed within the axisymmetric device housing and distributed radially around the longitudinal axis;
• a processor disposed within the axisymmetric device housing and coupled to the computer-readable memory, the processor configured to execute computer instructions stored in the computer-readable memory for interacting with a user via a voice assistant by processing voice commands received by the plurality of microphones;
• a wireless communication system disposed within the axisymmetric device housing;
• a first transducer disposed within the axisymmetric device housing and configured to generate sound waves within a first frequency range;
• a second transducer disposed within the axisymmetric device housing and configured to generate sound waves within a second frequency range lower than the first frequency range;
• an outer cover having a pattern formed thereon and disposed over the side surface of the axisymmetric device housing concealing audio components positioned beneath the outer cover, wherein the outer cover provides a consistent exterior surface of the voice-controlled electronic device and allows audio waves generated by the first transducer and the second transducer to pass through the outer cover;
• a touch-sensitive user interface disposed at the top surface of the axisymmetric device housing, the touch-sensitive user interface comprising capacitive touch sensors arranged to implement first and second touch buttons symmetrically positioned on opposite sides of the longitudinal axis, the first touch button enabling a user to increase speaker volume and the second touch button enabling a user to decrease speaker volume;
• a main logic board disposed within the axisymmetric device housing and having the processor mounted thereon;
• a second circuit board disposed within the axisymmetric device housing along a plane that is spaced apart from the user interface and perpendicular to the longitudinal axis, wherein at least one of the first transducer or the second transducer comprises a diaphragm configured to cool the second circuit board by pushing air toward the second circuit board during operation;
• and
• an amplifier board electrically coupled to a power supply unit and configured to provide power to the first and second transducers.
