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.

Appl. No.:

12/365748

Inventors:

Jason D. Silver - Framingham MA, US

International Classification:

G10K 13/00
H04R 7/20
H04R 7/16
H04R 7/18

US Classification:

181171, 181172

Abstract:

A surround for a diaphragm includes at least one rib section oriented to be extended during excursions of the diaphragm. The surround includes at least one membrane section supported by one or more rib sections contributing to a compliance characteristic different from the contribution of the one or more rib sections.

Appl. No.:

12/174768

Inventors:

Jason D. Silver - Framingham MA, US

Assignee:

Bose Corporation - Framingham MA

International Classification:

H04R 1/00

US Classification:

381398, 381403, 381423, 181171

Abstract:

An electroacoustical transducer includes a bobbin, a first acoustic radiator coupled to the bobbin through a first surround having a mechanical compliance, a second acoustic radiator generally rigidly coupled to the bobbin, and a basket. The first acoustic radiator is coupled to the basket through a second surround, and the second acoustic radiator is coupled to the basket through a third surround. The first surround is constructed to cause the first acoustic radiator to move out of phase with the second acoustic radiator relative to the bobbin when actuated by the bobbin at acoustic frequencies at and above a resonant frequency of the first acoustic radiator.

Appl. No.:

12/859396

Inventors:

Jason D. Silver - Framingham MA, US
Roman N. Litovsky - Newton MA, US

Assignee:

Bose Corporation - Framingham MA

International Classification:

G10K 13/00

US Classification:

181173, 181153, 381430

Abstract:

A three dimensional acoustic passive radiator diaphragm. A diaphragm a three dimensional volume. An acoustic driver radiates pressure waves into the three dimensional volume to cause the diaphragm to expand and contract. The three dimensional passive radiator may include a core of a porous, compressible material.

Assignee:

Bose Corporation - Framingham MA

International Classification:

H04R 1/02
H04R 1/20

US Classification:

381351

Abstract:

In an aspect, in general, a loudspeaker element includes an enclosure, a cone diaphragm of a driver element located within the enclosure, a first cavity wall extending from the cone diaphragm of the driver element to a throat opening which has an area less than an area of the cone diaphragm and forming a first cavity within the enclosure, an exit element extending from the throat opening to an environment outside of the enclosure, and an impedance compensation element extending from the first cavity wall, the impedance compensation element including a second cavity wall which forms a second cavity within the enclosure and a resistance element separating the second cavity from the first cavity.

Appl. No.:

13/600967

Inventors:

Roman N. Litovsky - Newton MA, US
Jason D. Silver - Framingham MA, US
Darius Mobed - Watertown MA, US

International Classification:

H04R 3/00

US Classification:

381152

Abstract:

A speaker includes a housing and four substantially similar electro-acoustic drivers secured inside the housing. The drivers are driven by substantially the same audio signal and are arranged such that the net mechanical vibrational force between the drivers and the housing is substantially zero. Four substantially similar passive radiators are secured inside the housing and driven by acoustic energy from the four drivers. The passive radiators are arranged such that the net mechanical vibrational force between the passive radiators and the housing is substantially zero.
