  • Subwoofer structure and adjusting method
    Patent number: 9014408
    Abstract: A subwoofer (10) structure comprised of a transducer (30) located in a loudspeaker enclosure (11), an acoustic duct (21) expanding in a horn-like manner, a frontal chamber (40) and an aperture (22). A sound wave emanating from the transducer is conveyed via the acoustic duct portion expanding in a horn-like manner to the frontal chamber, and a sound wave emanating from the opposite side of the transducer is conveyed either to a closed space (20) or directly to the frontal chamber. The subwoofer can be adjusted without altering the external dimensions of the loudspeaker enclosure, utilising the entire volume of the loudspeaker enclosure, so that the frontal chamber is tuned by altering the size of the frontal chamber and/or the size of the aperture in the frontal chamber.
