Abstract

Aspects of the invention can include a teleconferencing system having a system housing, a speaker enclosure configured within the system housing, a speaker mounted to the speaker enclosure, and one or more damping cushions coupling the speaker enclosure to the system housing. The one or more damping cushions can suspend the speaker enclosure within the system housing such that the speaker enclosure is separated and mechanically isolated from the system housing by at least a minimum distance (e.g., 2 mm). In some cases, the one or more damping cushions provide the only structural coupling between the speaker enclosure and the system housing. The one or more damping cushions can be configured to dampen mechanical energy generated by the speaker thereby preventing at least a portion of the mechanical energy form coupling to the system housing via the one or more damping cushions.

First claim

What is claimed is:

1. A teleconferencing system comprising:
a system housing;
a speaker enclosure configured within the system housing;
a speaker mounted to the speaker enclosure; and
one or more damping cushions coupling the speaker enclosure to the system housing, wherein the one or more damping cushions suspend the speaker enclosure within the system housing such that the speaker enclosure is isolated and separated from the system housing by at least a minimum distance,
wherein the one or more damping cushions provide an only structural coupling between the speaker enclosure and the system housing, and
wherein the one or more damping cushions are configured to dampen mechanical energy generated by the speaker thereby preventing at least a portion of the mechanical energy from coupling to the system housing via the one or more damping cushions.

2. The teleconferencing system of claim 1 wherein each of the one or more damping cushions is formed of a non-rigid and pliable compound.

3. The teleconferencing system of claim 2 wherein at least a portion of each of the one or more damping cushions is bulb-shaped.

4. The teleconferencing system of claim 1 wherein the one or more damping cushions are configured to support and suspend the speaker housing within the system housing along three dimensions.

5. The teleconferencing system of claim 1 further comprising:
a microphone disposed in the system housing,
wherein the one or more damping cushions are further configured to reduce an amount of mechanical energy generated by the speaker and coupled to the microphone via the one or more damping cushions.

6. The teleconferencing system of claim 1 wherein the one or more damping cushions dampen audio spectrum mechanical energy generated by the speaker and mechanically coupled to the system housing by at least 6 dB.

7. The teleconferencing system of claim 6 wherein the audio spectrum is a voice spectrum of 100 Hz—3000 Hz.

8. The teleconferencing system of claim 1 wherein the one or more damping cushions have a non-linear force response profile.

9. The teleconferencing system of claim 1 wherein the minimum distance is 2 mm.

10. A teleconferencing system comprising:
a system housing;
a speaker enclosure configured within the system housing;
a speaker mounted to the speaker enclosure;
one or more damping cushions coupling the speaker enclosure to the system housing, wherein the one or more damping cushions suspend the speaker enclosure within the system housing such that the speaker enclosure is isolated and separated from the system housing,
wherein the one or more damping cushions provide an only structural coupling between the speaker enclosure and the system housing, and
wherein the one or more damping cushions have a non-linear force response profile causing the one or more damping cushions to increase in compression resistance at an increasing rate as an increased compression is applied.

11. The teleconferencing system of claim 10 wherein at least a portion of each of the one or more damping cushions is bulb-shaped.

12. The teleconferencing system of claim 10 wherein each of the one or more damping cushions are formed of a non-rigid, pliable compound.

13. The teleconferencing system of claim 10 wherein the one or more damping cushions are configured to support and suspend the speaker housing within the system housing along three dimensions.

14. The teleconferencing system of claim 10 further comprising:
a microphone disposed in the system housing,
wherein the one or more damping cushions are further configured to reduce an amount of mechanical energy generated by the speaker and coupled to the microphone via the one or more damping cushions.

15. The teleconferencing system of claim 10 wherein the one or more damping cushions dampen audio spectrum mechanical energy generated by the speaker and mechanically coupled to the system housing by at least 6 dB.

16. The teleconferencing system of claim 10 wherein an audio spectrum of the teleconferencing system is a voice spectrum of 100 Hz—3000 Hz.

17. The teleconferencing system of claim 10 wherein the speaker enclosure is separated by at least a minimum threshold distance of 2 mm.

18. A teleconferencing system comprising:
a system housing;
a speaker enclosure configured within the system housing;
a speaker mounted to the speaker enclosure;
a microphone coupled to the system housing; and
one or more damping cushions coupling the speaker enclosure to the system housing, wherein the one or more damping cushions suspend the speaker enclosure within the system housing such that the speaker enclosure is isolated and separated from the system housing by at least a minimum distance,
wherein the one or more damping cushions provide an only structural coupling between the speaker enclosure and the system housing, and
wherein the one or more damping cushions dampen vibrational energy generated by the speaker thereby preventing at least a portion of any mechanical energy from coupling to the microphone via the one or more damping cushions by at least 6 dB.

19. The teleconferencing system of claim 18 wherein each of the one or more damping cushions is mounted in a particular axis, and wherein each of the one or more damping cushions provide dampening of the vibrational energy along both the mounted axis and at least one axis orthogonal to the mounted axis.

20. The teleconferencing system of claim 19 wherein at least a portion of the one or more damping cushions is bulb-shaped.
