  • Patent number: 9998820
    Abstract: An acoustic resonator device for reproducing sound in audio headphones having acoustic transducers coupled to resonating structures composed of various materials which react to the vibrations of the transducers. The resonator structures are designed with large surface areas by using projections of rigid materials of various shapes, sizes and quantities. These projections also resonate at different frequencies. The acoustic resonator reproduces sound from audio sources without compression waves being directed into the ear. These compression waves emanate from more typical audio drivers found in most headphones and can lead to listening fatigue as well as discomfort. The acoustic resonator device also produces a haptic effect which produces a richer sound, especially in the low frequency range. More than one acoustic transducer and resonator assembly is used to reduce distortion by dividing the frequency response into low and high/mid frequency ranges.
