The amplitude of that resonance at the input to the duct is minimised, hence assisting in filtering out the effect of that resonance without needing absorptive material. Ideally, it is placed at the intersection of two or more nodal surfaces. | 10-24-2013 |
| 20130284536 | SPEAKER DEVICE - A speaker device includes a cabinet from which a duct for adjusting the back pressure protrudes, a speaker unit mounted in the cabinet, and an intermediate hollow member including first and second connection portions. A cabin space in which the cabinet is installed is separated from a non-cabin space by a partition wall. If there is a subframe facing the partition wall, the duct cannot be directly connected to the opening formed in the partition wall. The intermediate hollow member is disposed in a small space between the subframe and the partition wall, the second connection portion is connected to the opening, and the duct is connected to the first connection portion. | 10-31-2013 |
| 20140262597 | TUBULAR BODY, BASS REFLEX PORT, AND ACOUSTIC APPARATUS - A tubular body having an air flow passage, wherein an area of a cross section, in a direction perpendicular to a tube axis, of a space enclosed with an inner wall of the tubular body increases toward an open end thereof, wherein a curvature of the inner wall at an end portion of the tubular body near the open end is repeatedly increased and decreased along a circumferential direction of the inner wall, and wherein, when the inner wall in a cross section of the end portion in the direction perpendicular to the tube axis is viewed from the tube axis, a convex portion at which the inner wall protrudes in a direction away from the tube axis and a concave portion at which the inner wall is recessed in a direction toward the tube axis are repeatedly formed along the circumferential direction. | 09-18-2014 |
| 20140262598 | BASS REFLEX PORT AND TUBULAR BODY - A bass reflex port having a tubular shape for air flows, wherein an angle of a first inner radial line with respect to a reference plane including a center axis of the bass reflex port differs from an angle of a second inner radial line with respect to the reference plane, the first line being orthogonal to the center axis and passing a first characteristic point on an inner circumference of the bass reflex port in a first transverse cross section perpendicular to the center axis, the second line being orthogonal to the center axis and passing a second characteristic point corresponding to the first characteristic point and located on the inner circumference in a second transverse cross section perpendicular to the center axis, the first transverse cross section and the second transverse cross section differing form each other in position in a direction of extension of the center axis. | 09-18-2014 |
| 20150096828 | AUDIO SPEAKER WITH EXTERNALLY REINFORCED PASSIVE RADIATOR ATTACHMENT - A battery powered wireless audio speaker comprising a passive radiator is disclosed. The perimeter portion of the passive radiator is sandwiched between the speaker chassis and the retention gasket that resides between an external overlying perforated cover to firmly secure the passive radiator. The construction is capable of being well suited to enhance and improve integrity to the seal between the passive radiator and the speaker chassis in strenuous environment conditions such as when a speaker is submerged in water. | 04-09-2015 |
