摘要： The present invention discloses an inventive microphone assembly for desktop communication systems. It utilises the advantages of placing the microphone in a desktop conferencing system as close as possible to the tabletop surface, without exposing the microphone for unfavourable mechanical or acoustic influence. This is achieved by building it into the footing in front of system, in a mechanically controlled and robust way. In this way, the high frequency response can be controlled to optimise sound quality, and at the same time the microphone assembly can be configured as a flexible unit that easily can be re-used in other systems.
