Abstract: An apparatus, system, and method for tuneful attenuation include at least one of speaker(s) and shaker(s) supported in a chair in a manner that enables at least one of resonance and even attenuation. In one embodiment, a shaker is mounted in a seat bottom by an attenuation member that includes a base and a plurality of somewhat flexible arms. The base is fixed to the shaker and the arms are coupled to a frame of the chair at positions that are at substantially equal distances from the shaker. Thus, the vibrations reach the frame at substantially the same time and are evenly and quickly attenuated. In other embodiments, the speakers and/or shakers are mounted in the chair by speaker cabinets that form part of and/or are rigidly fixed to the chair frame. In any case, vibrational energy transferred to the chair is better controlled and more tuneful.

Abstract: An apparatus, system, and method for an entertainment chair provide a high fidelity audio system incorporated in an entertainment chair. The entertainment chair is relatively independent from an acoustical environment in which it is placed, and enables repeatable high fidelity sound with a wide variety of recording types and qualities. The entertainment chair has high transparency and excellent imaging. Mid-range speakers and/or tweeters are placed in or near the armrests, forward of the seat occupant, and are oriented to face inward and upward. In one embodiment the mid-range and/or tweeters also angle rearward. A subwoofer is placed in the backrest and a shaker is placed in the seat bottom. The subwoofer and shaker are separately tunable through a control panel ergonomically placed at a forward end of an arm rest. The control panel includes a universal iPod dock. Other inputs may also be connected to the entertainment chair.
