Lightweight speaker enclosure
First Claim
1. An enclosure for a sound speaker comprising:
- a box section having side walls and a back wall which define a space for containing a speaker wherein said walls of said box section comprise a rigid substantially seamless outer layer, a middle sound absorbing layer, and a rigid substantially seamless inner layer wherein the middle sound layer is able to resist compression along a first direction more than along a second direction; and
a baffle section having at least one opening for allowing a diaphragm of said speaker to communicate therethrough wherein said baffle section is bonded to said front face of said box section to thereby enclose said speaker in an interior of said speaker enclosure.

Abstract
A speaker enclosure having a substantially seamless rigid outer skin, a middle sound absorbing layer, and a substantially seamless inner skin results in a lightweight speaker having sound absorbing characteristics. The speaker enclosure is comprised of two basic parts, a box section and a baffle section where each of these sections include a rigid outer skin, the middle sound absorbing layer and a seamless inner skin and are made according to the same method. The outer skin is formed from a layer of sheet molding compound, the middle sound absorbing layer includes pieces of honeycomb material, and the inner skin is formed from a layer of sheet molding compound. The layers of material are placed into a mold and then cured through vacuum bagging and heating thereby producing a strong, lightweight speaker enclosure made of materials which attenuate the transmission and retransmission of errant sound waves in the enclosure thereby reducing distortion of the sound signal produced by the speaker.
