Network Speaker
A loudspeaker is an electromechanical transducer that converts an electrical signal into sound. If locally powered, this can also be termed an active loudspeaker, meaning it contains an audio amplifier that can drive power to the speaker drivers. A network speaker implies the ability to drive audio to such a device from a network connection, usually an Ethernet network or Internet. In many cases this type of speaker also contains digital signal processing (DSP) to provide the audio crossover and other signal processing to provide frequency division and other tonal functions. Many network speakers contain multiple amplifiers, usually one per speaker driver. Network speakers are also known as IP speakers or IP loudspeakers. In many cases the IP speaker is created from an IP audio endpoint — a device as described above, but without the actual physical speaker portion — that provides amplified audio to a conventional loudspeaker.
Famous quotes containing the words network and/or speaker:
“Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?”
—George Eliot [Mary Ann (or Marian)
“If the oarsmen of a fast-moving ship suddenly cease to row, the suspension of the driving force of the oars doesn’t prevent the vessel from continuing to move on its course. And with a speech it is much the same. After he has finished reciting the document, the speaker will still be able to maintain the same tone without a break, borrowing its momentum and impulse from the passage he has just read out.”
—Marcus Tullius Cicero (106–43 B.C)
