Abstract
An acoustic variable porting system includes an acoustic element and an acoustic variable porting element forming a port into the acoustic element. The acoustic variable porting element is adjustable between at least an open position, in which the port is generally open, and a closed position, in which the port is generally closed. The acoustic element may be at least one of: a sub-kick, a ported drum, and a speaker.
Claims18
An acoustic variable porting system, comprising:
- an acoustic element that emits sound;
- an acoustic variable porting element comprising:
- a stationary register configured to be mounted to a housing adjacent to a resonant chamber;
- an adjustable register configured to be juxtaposedly mounted to the stationary register such that a degree of planar-rotational alignment between the stationary register and the adjustable register forms a port into the resonant chamber, wherein the port is positioned off-axis with respect to the resonant chamber, and wherein the size of the port is adjustable by adjusting the degree of planar-rotational alignment such that sound from the acoustic element is altered.
