Patent Images
1. A network speaker for an audio network distribution system, comprising:
- a network controller that controls the processing of the digital audio signal to and from the audio network distribution system;
a network interface that couples said network controller to the audio network distribution system;
an audio format converter that couples to said network controller and converts and formats the digital audio signal;
a digital to analog converter (DAC) that couples to said audio format converter and converts the digital audio signal to the analog audio signal;
a pre-amplifier that couples to said DAC and adjusts and filters the analog audio signal and an amplifier that couples to said pre-amplifier and amplifies the analog audio signal;
speaker sensors that couple to said pre-amplifier and provide feed back that enables internal auto adjustment to enhance speaker protection and performance and allow for sending control signals back to other devices in the audio network distribution system; and
a speaker/microphone driver that couples to said amplifier and provides the external connection to the speaker/microphone input output for the analog audio signal.
