Abstract
A Helmholz resonator loudspeaker having a capsule shape with substantial improvements over the existing art, including an improved way of mounting a driver on a tubular section, by having a gradual and continuous curved surface to connect the front of the driver to the tubular section without abrupt changes in geometry, thus creating an inverted horn; an improved way of mounting a resonator tube through one or both of the capsule ends to allow for optimum placement and reduction of curvature in the resonator tube; and ways to make a physical connection between two bass drivers mounted on opposing longitudinal sides of a tubular section in order to cancel out reaction forces.
Claims8
A Helmholtz resonator speaker, comprising:
- a speaker assembly;
- a speaker enclosure having a generally tubular shape with a hemispherical closure at each end of the tubular speaker enclosure so that the speaker enclosure forms a generally capsule shape;
- a first opening in said speaker enclosure, said first opening adapted to receive said speaker assembly so that the axis of the speaker assembly forms a generally right angle to the axis of the speaker enclosure;
- and
- a flange connecting said speaker enclosure and said speaker assembly so that the border between said speaker enclose and said speaker assembly comprises a smooth curve.
A Helmholtz resonator speaker, comprising:
- a speaker assembly;
- a speaker enclosure having a generally tubular shape with a hemispherical closure at each end of the tubular speaker enclosure so that the speaker enclosure forms a generally capsule shape;
- a first opening in said speaker enclosure, said first opening adapted to receive said speaker assembly so that the axis of the speaker assembly forms a generally right angle to the axis of the speaker enclosure;
- a second opening in said speaker enclosure, where said first opening and said second opening occupy the same plane.
A Helmholtz resonator speaker, comprising:
- a speaker assembly;
- a speaker enclosure having a generally tubular shape with a hemispherical closure at each end of the tubular speaker enclosure so that the speaker enclosure forms a generally capsule shape;
- a first opening in said speaker enclosure, said first opening adapted to receive said speaker assembly so that the axis of the speaker assembly forms a generally right angle to the axis of the speaker enclosure;
- a second opening in said speaker enclosure, where said first opening and said second opening occupy the same plane;
- and
- a tube member disposed within said speaker housing, said tube member having a first tube end and a second tube end, wherein said first tube end is disposed in said speaker enclosure and said second tube end is connected to said speaker enclosure as said second opening, and where said tube intersects one of said hemispherical closures.
A Helmholtz resonator speaker, comprising:
- a first speaker assembly;
- a second speaker assembly;
- a speaker enclosure having a generally tubular shape with a hemispherical closure at each end of the tubular speaker enclosure so that the speaker enclosure forms a generally capsule shape;
- a first opening in said speaker enclosure, said first opening adapted to receive said first speaker assembly so that the axis of the first speaker assembly forms a generally right angle to the axis of the speaker enclosure;
- a second opening in said speaker enclosure, where said first opening and said second opening are diametrically opposed to each other in the tubular speaker enclosure;
- and
- a support member in direct physical connection between said first speaker assembly and said second speaker assembly.
