Abstract
A method for designing and making an acoustic meta material back enclosure with a band gap tube for a loudspeaker having predefined dimensions of the enclosure is described. The method includes identifying a resonant frequency of the enclosure, as well as a baseline speaker output within a predefined range of frequencies. The method further includes defining a desired frequency range, within the predefined range of frequencies, within which it is desired to increase the speaker output, and identifying a naturally occurring band gap frequency range for the enclosure. Parameters of an acoustic meta material (AMM) band-gap tube, to be inserted into the enclosure for porting thereof, are calibrated to improve speaker output in the desired frequency range, based on the identified band gap frequency range. The enclosure is then ported using AMM band-gap tube in accordance with the calibrated parameters.
