Diaphragm Surround

US Patent:
7699139, Apr 20, 2010
Filed:
May 31, 2007
Appl. No.:
11/756119
Inventors:
K. Venkat Subramaniam - Westborough MA, US
Zhen Xu - Westford MA, US
Robert Preston Parker - Westborough MA, US
Jason D. Silver - Framingham MA, US
Assignee:
Bose Corporation - Framingham MA
International Classification:
H04R 7/18
H04R 7/20
H04R 1/28
G10K 13/00
H04R 7/16
H04R 1/20
US Classification:
181171, 181172, 381392
Abstract:
A surround for supporting a diaphragm used to create acoustic waves includes a rib section extending away from the diaphragm and a membrane section that is supported by the rib section. The membrane section has a thickness in a direction substantially normal to opposing top and bottom surfaces of the membrane section which is substantially thinner than a thickness of the rib section in a direction substantially normal to opposing top and bottom surfaces of the rib section. A restoring force returning the diaphragm to a home position is contributed to more due to deformation of the rib section than to deformation of the membrane section.

Diaphragm Surround

US Patent:
8397861, Mar 19, 2013
Filed:
Mar 2, 2012
Appl. No.:
13/410636
Inventors:
Zhen Xu - Waltham MA, US
Robert Preston Parker - Westborough MA, US
Allen T. Graff - Sutton MA, US
Assignee:
Bose Corporation - Framingham MA
International Classification:
H04R 7/20
H04R 7/18
H04R 1/28
H04R 1/22
H04R 7/16
H04R 1/20
US Classification:
181171, 181172, 381392
Abstract:
A surround for supporting a diaphragm used to create acoustic waves includes a plurality of first rib sections extending away from the diaphragm and a second rib section having a zigzag pattern and being secured to an end of each of the first rib sections. As the diaphragm starts moving away from a home position in an intended direction of travel which is substantially perpendicular to a plane in which the diaphragm lies when the diaphragm is in the home position, the zigzag pattern of the second rib section starts to straighten out.

Portable Loudspeaker

US Patent:
2018019, Jul 5, 2018
Filed:
Mar 2, 2018
Appl. No.:
15/910591

International Classification:
H04R 1/02
H04R 1/28
H04R 5/02
Abstract:
A loudspeaker includes a first electro-acoustic driver that creates sound waves when operated, and a housing. A first baffle is coupled to the housing and the first electro-acoustic driver. A first speaker grille covers the first electro-acoustic driver. A first gasket is disposed between the first baffle and the first speaker grille. The first gasket comprises a first set of energy directors to reduce buzzing between the first gasket and the first baffle.
