  • Acoustic structure
    Patent number: 8714303
    Abstract: An acoustic structure (e.g. an acoustic tuning panel) includes a plurality of boards and a plurality of resonance tubes with a plurality of openings. The openings are formed at different positions on the side faces of the resonance tubes. One resonance tube may be interposed in and supported by a pair of boards, or one board may be interposed in and supported by a pair of resonance tubes. The resonance tubes are mutually movable in the axial direction so as to independently adjust the opening area of the opening of the resonance tube. With this behavior, it is possible to adjust a ratio of the opening area of the resonance tube to the sectional area of the internal cavity of the resonance tube, thus adjusting the bandwidth of a band causing a sound-absorbing effect and a sound-scattering effect in an acoustic space (e.g. a sound chamber).

  • Electronic device
    Patent number: 7576998
    Abstract: A mountain-shaped angle member 20 is fixed to a side face 12 having a stepped portion of a mixer being an electronic device. The stepped portion is composed of a first wall portion projecting outward from the side face, a second wall portion recessed inward from the first wall portion, and a connecting portion connecting the first wall portion and second wall portion. Then, a fixing member is made capable of fixing the mountain-shaped angle member in either a first attachment mode in which the angle member is in contact with the first wall portion and opposed to the connecting portion or a second attachment mode in which the angle member is in contact with the first wall portion and overhangs outward the first wall portion.
