Standing wave reducing
First Claim
Patent Images
1. A loudspeaker enclosure for reducing standing waves occurring at one or more frequencies, wherein the enclosure has an inner surface defining a cavity, the enclosure comprising:
- a first end;
a second end;
a first sidewall;
an internal barrier having a first side and a second side attached to the inner surface of the enclosure along the first sidewall of the enclosure, partially extending into the cavity of the enclosure and extending from the first end of the enclosure to the second end of the enclosure, wherein the internal barrier forms a resistive coupling between the first and second sides.

Abstract
The frequency at which standing waves occur in a loudspeaker enclosure may be reduced by the addition of an internal barrier to the enclosure in order to lengthen the effective length of an internal dimension of the enclosure. Additionally, the internal barrier may be configured such that it forms a resistive coupling between two sides of the barrier. By configuring the internal barrier to form a resistive coupling, aberrations in the frequency response of the loudspeaker caused by certain standing waves may be dampened.

25. A method for reducing standing waves in the frequency response of a loudspeaker having a driver at least partially enclosed by an enclosure having internal dimensions and external dimensions, the method comprising:
-
increasing the effective length of at least one internal dimension of the enclosure without changing the external dimensions of the enclosure; and forming a resistive coupling between two ends of a standing wave by providing a barrier comprised of a flexible material capable of resistively flexing during normal play operations. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
