Polyphonic Guitar Pickup For Sensing String Vibrations In Two Mutually Perpendicular Planes

View page
US Patent:
6392137, May 21, 2002
Filed:
Apr 27, 2000
Appl. No.:
09/559569
Inventors:
Osman K. Isvan - Nashville TN
Assignee:
Gibson Guitar Corp. - Nashville TN
International Classification:
G10H 318
US Classification:
84726
Abstract:
A transducer for detecting vibrations in an object. Multiple pickup coils are utilized which are sensitive to both the vibrations in the string plane and the vibrations perpendicular to the string plane. This system subtracts the signals from the first and second pickups to create a signal representing the vibrations in the string plane and combines the signals from the first pickup and the second pickup for determining the string vibrations perpendicular to the string plane. In one embodiment of the invention, the transducer uses one pole of the pickup as a bridge saddle for supporting the guitar string. The saddle pole of the pickup is constructed from a magnetically permeable material. The saddle pole causes the lines of magnetic flux to be carried in large part by the guitar string and allows for a reduction in the total magnetic energy requirement for the pickups permanent magnet to reduce the cross talk between adjacent string sensors within a polyphonic pickup.

09/990097
Inventors:
Osman K. Isvan - Aptos CA, US
Assignee:
Plantronics, Inc. - Santa Cruz CA
International Classification:
H03G 3/00
US Classification:
381104, 379430, 381122
Abstract:
A communications headset with a movable microphone boom that extends to different distances from the mouth, where the movement of the boom operates electrical, mechanical or acoustic means to adjust the transmit and/or receive sensitivity of the headset.

Personal Communication Method And Apparatus With Acoustic Stray Field Cancellation

View page
US Patent:
7499555, Mar 3, 2009
Filed:
Dec 2, 2002
Appl. No.:
10/308810
Inventors:
Osman K. Isvan - Aptos CA, US
Assignee:
Plantronics, Inc. - Santa Crux CA
International Classification:
A61F 11/06
G10K 11/16
H03B 29/00
US Classification:
381 716, 381 717, 381182, 381186, 381380
Abstract:
Personal communication method and apparatus, such as telephone handsets and headsets, with acoustic stray field cancellation are disclosed. The personal communications device employs an echo canceling receiver generally including two displacement sources that are not in phase formed by at least one driver, an acoustic cavity corresponding to each displacement source, and an acoustic output port corresponding to and in acoustic connection with each displacement source via the corresponding acoustic cavity such that the acoustic length between the acoustic centers of the two ports is less than the distance between the acoustic center of each port and the acoustic center of the corresponding displacement source to which the port is acoustically connected. In another embodiment, the ports may be such that both ports are located on a same side of a surface of at least one of the displacement sources. As an example, the personal listening device may have at least two ports and a dedicated driver acoustically coupled to each port.

Abstract:
A miniaturized acoustic boom structure includes a microphone boom housing having a wind screen and a microphone pod configured to hold a microphone. The microphone pod has an outer surface secured to an inner surface of the microphone boom housing, an interior having one or more surfaces configured to form an acoustic seal around at least a portion of the periphery of the microphone, and first and second pod port openings. The first and second pod port openings provide sound wave access to opposing sides of a diaphragm of the microphone, and are shaped and spaced away from the first and second microphone ports of the microphone so that an acoustic path length between the first and second pod port openings is greater than an acoustic path length between the first and second microphone ports.
