Abstract: Multiple speakers and isobaric chambers are used to enhance sound quality in an earbud. The earbud has a housing with a sound outlet, a first and second isobaric chambers that are in communication with the outlet. Two sound drivers in the housing are positioned to emit sound waves into the isobaric chambers separately. A divider is used to guide sound waves by creating an elongated channel in the second isobaric chamber. An ear hook has a third isobaric chamber and a third sound driver positioned to emit sound wave into the third isobaric chamber. The third isobaric chamber is in communication with the outlet through the second isobaric chamber.

Abstract: A speaker system uses multiple sound chambers having phi ratios to create a dampening effect to filter out incoherent sounds, thus creating an enhanced listening experience that feels very natural to the listener. The speaker system has at least a sound driver, a first sound chamber having a first volume, and a second sound chamber having a second volume that is approximately 1.6 times the first volume. The speaker system can also have a second sound driver, and a third sound chamber having a third volume that is that is approximately 1.6 times the second volume.
