Audio driver and power supply unit architecture

An electronic device, comprising:

• a device housing;
• a computer-readable memory disposed within the device housing;
• a microphone disposed within the device housing;
• a processor disposed within the 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 and processing voice commands received by the microphone;
• a wireless communication system disposed within the device housing and configured to transmit the voice commands to a remote server for further processing;
• and
• audio driver assemblies arranged in a circular configuration within the device housing, each audio driver assembly including:
• a diaphragm dividing an interior volume within the audio driver assembly into a front volume and a rear volume
• a voice coil assembly disposed within the rear volume, each audio driver assembly oriented such that audio waves generated by the diaphragm within the front volume are initially oriented toward a central region of the circular configuration.

An electronic device, comprising:

• an axisymmetric housing;
• a computer-readable memory disposed within the axisymmetric housing;
• a microphone;
• a processor disposed within the axisymmetric 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 and processing voice commands received by the microphone;
• a wireless communication system disposed within the axisymmetric housing and configured to relay the voice commands to a remote server for further processing;
• and
• an array of audio driver assemblies disposed within the axisymmetric housing at a regular radial interval, each of the audio driver assemblies being configured to generate audio waves that exit the axisymmetric housing through acoustic vents defined by a downward facing end of the axisymmetric housing.

• and
• audio driver assemblies distributed radially about an interior of the device housing, diaphragms of each audio driver assembly arranged so that audio waves generated by the diaphragms are initially oriented toward a central region of the device housing and then reoriented toward a periphery of the device housing by a channel coupled to each of the audio driver assemblies.

A voice-controlled electronic device, comprising:

• a device housing;
• a wireless communication system disposed within the device housing;
• a computer-readable memory disposed within the device housing;
• a microphone disposed at an exterior surface of the device housing;
• one or more processors disposed within the device housing and coupled to the computer-readable memory, the one or more processors configured to execute computer instructions stored in the computer-readable memory for interacting with a user and processing voice commands received by the microphone after recognizing a command phrase indicating a user's intent to issue a voice command;
• audio driver assemblies distributed radially about an interior of the device housing, each of the audio driver assemblies including a diaphragm and an audio channel providing a path for sound generated by the diaphragm to exit a driver housing;
• an amplifier board electrically coupled to each of the audio driver assemblies, the amplifier board defining a central opening through which a longitudinal axis of the device housing extends;
• and
• a power supply unit positioned between two or more of the audio driver assemblies and operatively coupled to provide power to the one or more processors, wireless communication system, microphone and audio driver assemblies,
• wherein the power supply unit extends through the central opening defined by the amplifier board.
