Sealing, absorbing, and decoupling speaker ring kit

摘要

An acoustic system kit for a vehicle speaker and associated methods of installation and manufacture are disclosed. A drum of open-cell foam, preferably several inches thick, having a peel-and-stick pressure-sensitive adhesive backing is cut with two concentric circles to create an outer ring, and inner ring, and a core. The parts are sized to correspond in diameter, respectively, to the front edge, rear edge, and back disc of a particular size of speaker. The inner ring is cut circumferentially to reduce its height to a thin strip relative to the outer ring and drum. Using the pressure-sensitive adhesive, the core is affixed to the inside wall of vehicle door directly behind the door's speaker mount, the inner ring is affixed to the rear edge of a speaker to be installed, and the outer ring is affixed to front edge of the speaker. The speaker is then installed on its mount.

主权项

1. A method of manufacturing an acoustic system kit, said acoustic system kit comprising:
(a) an outer ring; (b) an inner ring; (c) a core; (d) said outer ring having the shape of a hollow cylinder having an outer circumferential surface, an inner circumferential surface, a top surface and a bottom surface; (e) said inner ring having the shape of a hollow cylinder having an outer circumferential surface, an inner circumferential surface, a top surface and a bottom surface; (f) said core having the shape of a cylindrical prism having an outer circumferential surface, a top surface, and a bottom surface; (g) said outer ring being made of a first compressible material; (h) said inner ring being made of a second compressible material; (i) said core being made of a third compressible material; (j) said outer ring having a first adhesive affixed to its bottom surface; (k) said inner ring having a second adhesive affixed to its bottom surface; (l) said core having a third adhesive affixed to its bottom surface; (m) the inner diameter of said outer ring is equal to the outer diameter of said inner ring; (n) the inner diameter of said inner ring is equal to the outer diameter of said core; (o) said outer ring and said core are of equal axial thickness;and said method of manufacturing comprising:
(a) producing a drum made of a compressible material; (b) the axial thickness of said drum being equal to the intended axial thickness of said outer ring and said core; (c) the outer diameter of said drum being equal to the intended outer diameter of said outer ring; (d) applying an adhesive to the bottom surface of said drum; and (e) making a first circular cut and a second circular cut in said drum; (f) said first circular cut and said second circular cut both being parallel to the axial line of said drum; (g) the diameter of said first circular cut being equal to the intended inner diameter of said outer ring and the intended outer diameter of said inner ring; (h) the diameter of said second circular cut being equal to the intended inner diameter of said inner ring and the intended outer diameter of said core; whereby said drum is separated into said outer ring, said inner ring, and said core.
