Ambient Noise Isolation Audio Headphones Having A Layered Dampening Structure

US Patent:
8358799, Jan 22, 2013
Filed:
Nov 1, 2010
Appl. No.:
12/917058
Inventors:
Johnny J. Gresko - Arnold MO, US
Stephen J. Rois - Webster Groves MO, US
International Classification:
H04R 25/00
US Classification:
381371, 381370, 381372
Abstract:
An audio headphone apparatus having ambient noise isolation properties for musicians and sound engineers which allows a user to substantially attenuate ambient noise levels and focus on the electronic audio presented to the headphones. The apparatus utilizes a unique layering of absorber materials with unique geometric shapes which in combination highly attenuate external ambient acoustic energy and control undesirable “boomy” bass response. The apparatus further has a jack adapter holder which retains a inch adapter for use with an external plug on the headphones.

Ambient Noise Isolation Audio Headphones Having A Layered Dampening Structure

US Patent:
7853034, Dec 14, 2010
Filed:
Jan 17, 2006
Appl. No.:
11/333176
Inventors:
Johnny J. Gresko - Arnold MO, US
International Classification:
H04R 25/00
US Classification:
381372, 381370, 381371
Abstract:
An audio headphone apparatus having ambient noise isolation properties for musicians and sound engineers which allows a user to substantially attenuate ambient noise levels and focus on the electronic audio presented to the headphones. The apparatus utilizes a unique layering of absorber materials with unique geometric shapes which in combination highly attenuate external ambient acoustic energy and control undesirable “boomy” bass response. The apparatus further utilizes a desiccant material within the ear cuff cover which helps to absorb perspiration or other moisture.

Apparatus And Methods For Limiting Sound Volume In Headphones

US Patent:
20140105414, Apr 17, 2014
Filed:
Oct 15, 2012
Appl. No.:
13/651916
Inventors:
- St. Louis MO, US
Stephen John Rois - Webster Groves MO, US
Johnny Joseph Gresko - Arnold MO, US
Assignee:
DIRECT SOUND HEADPHONES, LLC - St. Louis MO
International Classification:
H03G 3/20
H04R 1/10
US Classification:
381 74, 381107
Abstract:
Exemplary embodiments or implementations are disclosed of methods, apparatus, and systems for a volume limiter circuit. A rectifier sub-circuit is configured to rectify at least a portion of an audio signal received from an audio source. A junction field effect transistor (JFET) has a channel connected in series between the audio source and a speaker. A feedback sub-circuit is configured to provide a gate signal at a gate of the JFET and to modulate a control signal in accordance with the audio signal crossing the JFET channel. The feedback sub-circuit is connected with the rectifier sub-circuit so as to extend a range of variable resistance of the JFET channel. The limiter circuit provides functionality that changes in response to varying audio voltages.
