Abstract
The inventive subject matter is directed to headset audio systems having resonance chambers designed to improve a system's frequency response in certain ranges. Systems of the inventive subject matter include a casing that both holds a speaker driver and creates two resonance chambers. Each resonance chamber vents to ambient air outside the casing, where the length and cross-sectional areas of each vent can impact the system's frequency response. Each resonance chamber is tuned to a resonant frequency to improve the system's frequency response across a range of frequencies on either side of each chamber's resonant frequency.
