Desktop terminal foot and desktop system
View Patent ↗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.
1. A desktop terminal, comprising:
an omni directional microphone element encapsulated in a foot, wherein a membrane of the omni directional microphone element is vertically oriented with respect to a horizontal support surface; and
an inclined channel, downwardly extending from a first inlet of said microphone element to a second inlet of a non-horizontal surface of the foot, wherein
said second inlet is positioned on said non-horizontal surface at a height in the range of 0.5 mm to 1.5 mm above an upper edge of the horizontal support surface, and said foot is configured to support a telecommunication terminal on the horizontal support surface.
2. The desktop terminal according to claim 1 , wherein the omni directional microphone element is an electret condenser microphone connected to the telecommunication terminal as a main audio input.
3. The desktop terminal according to claim 1 ,
wherein the channel has a width in the range of 1 mm to 3 mm, and a length in the range of 3 mm to 7 mm.
4. The desktop terminal according to claim 1 , wherein
said foot is made of an elastomer cast of at least 35 shore hardness.
5. The desktop terminal according to claim 1 , wherein
said foot is configured as a detachable component of the telecommunication terminal.
6. The desktop terminal according to claim 3 , wherein said foot is configured as a detachable component of the telecommunication terminal.
7. The desktop terminal according to claim 1 ,
wherein said telecommunication terminal is a video conference end-point.
8. A desktop system, comprising:
an omni directional microphone;
a display;
one or more loudspeakers; and
a codec in a housing supported by a foot,
wherein the microphone is encapsulated in the foot, a membrane of the omni directional microphone element is vertically oriented with respect to horizontal support surface, and the foot includes an inclined channel, downwardly extending from a first inlet of said omni directional microphone to a second inlet of a non-horizontal surface on a front side of the foot, the second inlet is positioned on said non-horizontal surface at a height in the range of 0.5 to 1.5 mm above an upper edge of the horizontal support surface, and said foot is configured to support said desktop system on the horizontal support surface.
9. The desktop system according to claim 8 ,
wherein the omni directional microphone is an electret condenser microphone.
10. The desktop system according to claim 8 ,
wherein the channel has a width in the range of 1 mm to 3 mm, and a length in the range of 3 mm to 7 mm.
11. The desktop system according to claim 8 , wherein said foot is made of an elastomer cast of at least 35 shore hardness.
