Abstract
The invention relates generally to the field of audio loudspeaker enclosures, and more particularly to a method of mounting the internal components in the loudspeaker so as to control the loudspeaker output. Specifically a mounting structure and method for mounting the loudspeaker horn to its associated compression driver are disclosed. The mounting structure allows the directivity of the loudspeaker output, and the frequency/phase control of the loudspeaker, output to be controlled by the spatial arrangement of these components in the loudspeaker enclosure.
Claims29
An audio loudspeaker assembly comprising:
- an enclosure;
- an inner baffle structure mounted inside said enclosure and operatively attached to said enclosure;
- at least one low frequency subassembly operatively mounted on said baffle structure, said low frequency subassembly having a low frequency horn;
- and
- a high frequency subassembly operatively mounted on said baffle structure, said high frequency subassembly having a high frequency horn.
A method of constructing an audio loudspeaker, said method comprising:
- providing an enclosure;
- providing an inner baffle structure mounted inside said enclosure and operatively attached to said enclosure;
- providing at least one low frequency subassembly operatively mounted on said baffle structure, said low frequency subassembly having a low frequency horn front end;
- and
- providing a high frequency subassembly operatively mounted on said baffle structure, said high frequency subassembly having a high frequency horn front end.
An audio loudspeaker system comprising:
- a primary control system for controlling the directivity of the loudspeaker system, said primary control system responsive to a broadband directivity characteristic factor, said directivity factor representative of the directional capability of the audio output of the loudspeaker system;
- and
- wherein said directivity factor is directly proportional to the frequency of operation across the audible frequency range, producing a linear directivity characteristic.
A method of controlling directivity in a loudspeaker system, said method comprising:
- providing a loudspeaker enclosure, said loudspeaker enclosure including a high frequency horn and at least one low frequency horn;
- mounting said high frequency horn and said low frequency horn on the same baffle with said loudspeaker enclosure;
- and
- providing a primary control system for controlling the directivity of the loudspeaker system, said primary control system operationally coupled to said low frequency horn and said high frequency horn.
An acoustic performance system comprising:
- an venue area designated for an acoustic performance;
- one or more loudspeaker enclosures distributed in said venue area, said loudspeaker enclosures adapted to provide amplification and distribution of said acoustic performance;
- at least one of said loudspeaker enclosures further comprising;
- a baffle structure mounted inside said enclosure and operatively attached to said outer enclosure;
- at least one low frequency subassembly operatively mounted on said baffle structure, said low frequency subassembly having a low frequency horn front end;
- and
- a high frequency subassembly operatively mounted on said baffle structure, said high frequency subassembly having a high frequency horn front end.
