Abstract

The self sealing speaker gasket is constructed of thin mylar (005" Max) in a cone shape and glued to the speaker. The large diameter of the cone shaped gasket is approximately 5% larger than the diameter of the cylindrical speaker carder. (See Fig. 1.) During insertion of the speaker with the gasket to the speaker carrier, the large diameter of the gasket is compressed to the size of the carrier and generates enough tension between the gasket and the carrier to provide and maintain good sealing between them.

SELF SEALING SPEAKER GASKET

by Richard Gordecki

   The self sealing speaker gasket is constructed of thin mylar (005" Max) in a cone shape and glued to the speaker. The large diameter of the cone shaped gasket is approximately 5% larger than the diameter of the cylindrical speaker carder. (See Fig. 1.) During insertion of the speaker with the gasket to the speaker carrier, the large diameter of the gasket is compressed to the size of the carrier and generates enough tension between the gasket and the carrier to provide and maintain good sealing between them.

   Due to the fact that for high efficiency speakers the back cavity is usually designed as a closed chamber, the sound pressure generated in the back cavity and configuration of the self sealing gasket increases sealing efficiency of the gasket.

The self sealing speaker gasket can also serve as a self locating and self locking device if the diameter of the carrier is stepped (See Fig. 2).
