Patent number: 11716563Abstract: A loudspeaker system includes a subwoofer. The subwoofer includes a housing having a plurality of walls which together define an acoustic cavity. The plurality of walls includes a front wall, a rear wall, a top wall, a bottom wall, and a plurality of sidewalls extending between the top and bottom walls and between the front and rear walls. A first transducer mounted to the front wall of the housing. The first transducer includes a diaphragm having a major axis and a minor axis. The major axis has a fist end proximate the bottom wall and an opposite, second end proximate the top wall, such that the major axis is arranged vertical, relative to ground when the subwoofer is rested on its bottom wall. The top wall has a handle such that the loudspeaker can be carried with the major axis arranged vertical to ground.Type: GrantFiled: June 14, 2021Date of Patent: August 1, 2023Assignee: Bose CorporationInventors: Greg J. Zastoupil, Peter P. Premo, Peter C. Santoro, Craig Small, Joseph J. Kutil, David Edwards Blore

Patent number: 11310587Abstract: A loudspeaker includes a first electro-acoustic transducer, a horn acoustically coupled to the first electro-acoustic transducer, and a first acoustic leak that is acoustically coupled to the horn. The first acoustic leak is positioned so as to reduce a peak in a frequency response of the loudspeaker at the targeted frequency without removing the targeted frequency from the output of the loudspeaker.Type: GrantFiled: October 8, 2019Date of Patent: April 19, 2022Assignee: Bose CorporationInventors: David Edwards Blore, Randy J. Kulchy, Robert Preston Parker

Patent number: 9894432Abstract: 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.Type: GrantFiled: September 2, 2016Date of Patent: February 13, 2018Assignee: Bose CorporationInventors: David Edwards Blore, Paul F. Fidlin, Soichiro Hayashi, Thomas E. MacDonald, Peter C. Santoro

Patent number: 9049519Abstract: A horn loudspeaker with gain shading. The horn loudspeaker includes an acoustic horn. The acoustic horn includes side walls, for determining the horizontal dispersion angle of the acoustic horn, top and bottom walls, for determining the vertical dispersion angle of the acoustic horn, and a plurality of acoustic drivers coupled to the acoustic horn by a diffraction slot having segments. Each of the segments is separated from the adjacent segments by less than one half of the wavelength of the highest frequency of the operational range of the horn loudspeaker. The horn loudspeaker further includes circuitry for transmitting an audio signal to the plurality of acoustic drivers, the circuitry comprising a first signal attenuation element electrically coupling an audio signal input element and a first of the acoustic drivers.Type: GrantFiled: February 18, 2011Date of Patent: June 2, 2015Assignee: Bose CorporationInventors: David Edwards Blore, Paul F.
