Filed:

Oct 6, 2010

Appl. No.:

12/898947

Inventors:

David Edwards Blore - Westborough MA, US
Paul F. Fidlin - Wayland MA, US
Soichiro Hayashi - Framingham MA, US
Thomas E. Macdonald - Boston MA, US
Peter C. Santoro - Shirley MA, US

International Classification:

H04R 1/02

US Classification:

381338

Abstract:

A modular horn type loudspeaker and a modular horn array formed of modular loudspeakers. An acoustic horn includes a first acoustic module. The first acoustic module includes a first acoustic driver and a first acoustic duct, for conducting acoustic energy from the first acoustic driver. The first acoustic duct has a first opening through which acoustic energy is radiated. The first acoustic duct is characterized by a first centerline. A second acoustic module includes a second acoustic driver and a second acoustic duct, for conducting acoustic energy from the acoustic driver. The second acoustic duct has a second opening through which acoustic energy is radiated. The second acoustic duct is characterized by a second centerline. The first module and the second module are configured to be positioned and held in place so that the first and second openings are aligned to form a substantially continuous diffraction slot and so that the first and second centerlines are normal to an arc and intersect at a first one of a plurality of angles.

International Classification:

H05K 7/20
H04R 1/40
H04R 1/02

Abstract:

A loudspeaker system includes a line array assembly and a base for supporting the line array assembly. The line array assembly includes a plurality of electro-acoustic transducers arranged along a vertical axis and the base houses electronics for powering the line array assembly. The base and the line array assembly together define a flow path to facilitate a convective air flow to pass between the base and the line array assembly for cooling the electronics.
