Abstract
A venturi expander is mounted on a speaker enclosure to receive the rearward-propagated sound waves and to extend the propagation path. The venturi expander's reflective sides direct the rearward sound to the sides or top or bottom of the speaker enclosure to produce a reflected sound surrounding the speaker enclosure and producing sound to the sides of the speaker substantially as projected from the front of the speaker.
Claims29
A speaker enclosure venturi expander, comprising,
- a speaker enclosure having a front wall, rear wall, and a side wall, respectively;
- a speaker having a speaker front and a speaker rear;
- said speaker mounted in said front wall of said speaker enclosure with said speaker front opening to ambient and said speaker rear inside said enclosure;
