Abstract
A compression driver includes a phasing plug including a base portion having a first side and an opposed second side, the first side including a central hub portion extending outwardly from the first side, the base portion including one or more apertures that extend therethrough from the first side to the second side. A diaphragm is disposed adjacent the phasing plug second side, and a compression chamber defined between the diaphragm and the phasing plug. In one embodiment, a front plate is attached to the phasing plug first side, the front plate having a central aperture generally aligned with the hub portion and base portion apertures. A horn may be attached to the front plate or directly to the phasing plug first side.
Claims20
A compression driver, comprising:
- a phasing plug including a base portion having a first side and an opposed second side, the first side including a central hub portion extending outwardly from the first side, the base portion including one or more apertures that extend therethrough from the first side to the second side;
- a diaphragm disposed adjacent the phasing plug second side;
- a compression chamber defined between the diaphragm and the phasing plug;
- and
- a front plate attached to the phasing plug first side, the front plate having a central aperture generally aligned with the hub portion and the base portion apertures, the central aperture forming an exit of the compression driver.
A horn driver, comprising:
- a phasing plug including a base portion having a first side and an opposed second side, the first side including a central hub portion extending outwardly from the first side, the base portion including one or more apertures that extend therethrough from the first side to the second side;
- a diaphragm disposed adjacent the phasing plug second side;
- a compression chamber defined between the diaphragm and the phasing plug;
- a front plate attached to the phasing plug first side, the front plate having a central aperture generally aligned with the hub portion and base portion apertures;
- and
- a horn attached to the front plate, the horn having an inlet and an outlet, wherein the horn inlet is generally aligned with the central aperture.
A horn driver, comprising:
- a phasing plug including a base portion having a first side and an opposed second side, the first side including a central hub portion extending outwardly from the first side, the base portion having apertures that extend therethrough from the first side to the second side;
- a diaphragm disposed adjacent the phasing plug second side;
- a compression chamber defined between the diaphragm and the phasing plug;
- and
- a horn attached to the phasing plug first side, the horn having an inlet and an outlet, wherein the horn inlet is generally aligned with the hub portion and the base portion apertures.
