Abstract
A high frequency horn for use in a multiple frequency loudspeaker system having a midrange transducer and a high frequency transducer is disclosed. The high frequency horn includes a horn chamber, horn mouth, a horn throat, a tuned resonant cavity, and a port connected to both the tuned resonant cavity and the horn chamber. The horn throat and horn chamber are located on opposite sides of the horn chamber, the port is located proximate to the horn throat, and the horn throat is configured to be connected to the high frequency transducer. The tuned resonant cavity is tuned to reduce high frequency standing waves produced by the midrange transducer within the horn chamber.
Claims16
A high frequency horn for use in a multiple frequency loudspeaker system having a midrange transducer and a high frequency transducer, the high frequency horn comprising:
- a horn chamber, a horn mouth, and a horn throat, wherein the horn throat and the horn mouth are located on opposite sides of the horn chamber;
- a sound vane disposed in the horn chamber;
- a tuned resonant cavity located at least partially within the vane;
- and
- a port provided on the vane proximate to the horn throat, the port connecting the tuned resonant cavity to the horn chamber,
- wherein the horn throat is configured to be connected to the high frequency transducer, and
- wherein the tuned resonant cavity is tuned to reduce high frequency standing waves produced by the midrange transducer within the horn chamber.
A high frequency horn comprising:
- a pair of opposing side walls;
- a pair of flared sides connecting the pair of opposing side walls and defining a horn chamber diverging from a horn throat at one end of the horn to a horn mouth at an opposite end;
- a vane positioned within the horn chamber to disperse sound, the vane including a vane chamber defining at least a portion of a resonant cavity;
- and
- at least one port provided on the vane connecting the horn chamber to the resonant cavity.
