Abstract
A speakerphone calibration system (system) is provided herein, comprising: a calibration unit adapted to generate at least one test signal, and further adapted to determine at least one calibration factor in response to at least one test signal, and wherein a first calibration factor characterizes a speakerphone system under test in regard to mechanical vibrations generated in the speakerphone system under test, the mechanical vibrations caused by a first test signal.

A speakerphone calibration system (system), comprising:
- a calibration unit adapted to generate at least one test signal, and
- further adapted to determine at least one calibration factor in response to at least one test signal, and wherein
- a first calibration factor characterizes a speakerphone system under test in regard to mechanical vibrations generated on an enclosure of the speakerphone system under test, the mechanical vibrations caused by a first test signal.
A speakerphone system comprising:
- a processor adapted to generate at least one test signal, and
- further adapted to determine at least one calibration factor in response to at least one test signal, and wherein
- a first calibration factor characterizes the speakerphone system during calibration in regard to mechanical vibrations generated on an enclosure of a speakerphone system under test, the mechanical vibrations caused by a first test signal;
- a first communications interface adapted to transmit the first test signal to the speakerphone system under test, and wherein the speakerphone system under test comprises—
- a microphone (mic) adapted to receive acoustic energy and convert the same to a mic electrical signal;
- a second communications interface adapted to receive the first test signal;
- a second processor;
- a loudspeaker adapted to receive an electrical audio signal and broadcast the same as an acoustic signal;
- a mechanical vibration sensor (MVS) adapted to sense vibrations on the enclosure of the speakerphone system under test and convert the same to an MVS electrical signal.
