Abstract: A telecommunications device (1) comprises a base part (2), a cap part (4), a body part (3), a control panel (5), an upper light ring (9), a lower light ring (8), a plurality of sound microphones and a plurality of sound speakers. The cap part (4) is concave in shape. The body part (3) is frusto-conical in shape and tapers outwardly away from the cap part (4) towards the base part (2). The body part (3) and the cap part (4) cover the sound microphones and the sound speakers. The control panel (5) is inclined relative to the plane of the support surface (6) and relative to the plane of the base part (2). The control panel (5) protrudes upwardly from the upper edge of the body part (3) over the concave cap part (4), and the control panel (5) protrudes downwardly from the lower edge of the body part (3). The control panel (5) controls operation of the sound microphones and the sound speakers. The upper light ring (9) is located between the cap part (4) and the body part (3).

Abstract: A communication system that includes multiple conferencing devices connected in a daisy-chain configuration is communicably connected to far-end conference participants. Multiple conferencing devices provide improved sound quality to the far-end participants by reducing aural artifacts resulting from reverberation and echo. The daisy-chain communication system also reduces the processing and transmission time of the near-end audio signal by processing and transmitting the audio signal in frequency domain. Each conferencing device in the daisy chain performs signal conditioning on its audio signal before transmitting it in the frequency domain to a mixer. The output signal of the mixer is converted back to the time domain before being transmitted to the far-end. The daisy-chain configuration also provides a distributed bridge to external communication devices that can be connected to each conferencing device.
