Abstract
An acoustic damping device having a hollow cone partially filled with an acoustic damping medium. The cone is composed of solid material such as wood. The acoustic damping medium can be a particulate solid, such as metal powder, or a liquid. The acoustic damping device is placed between a speaker and a speaker platform to reduce the amount of vibrational interference that reaches the speaker.
Claims23
An acoustic damping device for supporting a speaker cabinet above a platform, comprising
- a shell of solid material having a generally flat top surface for contacting the speaker cabinet and a rounded bottom surface for contacting the platform;
- and
- an acoustic damping medium at least partially filling said shell.
An acoustic damping device for supporting a speaker cabinet above a platform, comprising
- a shell of solid material having a generally flat top surface for contacting the speaker cabinet and a rounded bottom surface for contacting the platform;
- an acoustic damping medium at least partially filling said shell;
- and
- a cover attached to said shell.
An acoustic damping device for supporting a speaker cabinet above a platform, comprising
- a hemispherical shell of solid material having a circular cross-section taken perpendicular to an axis extending from the speaker cabinet to the platform, a generally flat top surface for contacting the speaker cabinet, and a non-uniform wall thickness;
- and
- an acoustic damping medium filling at least 1/4 of the shell.
