Filed:

Nov 17, 2005

Appl. No.:

11/281097

Inventors:

Medford Alan Dyer - San Diego CA, US
Jerry J. Harvey - Newport Beach CA, US
Robert G. Allison - San Juan Capistrano CA, US

Assignee:

Logitech International, S.A.

International Classification:

H04R 25/00

US Classification:

381322, 381328

Abstract:

An audio monitor system that includes a pair of in-ear monitors, each of which includes a connector and a corresponding detachable cable, is provided. Each connector may include a two pin jack assembly and each detachable cable may include a corresponding two pin plug assembly. Preferably, each plug assembly of each detachable cable includes a hooded member. More preferably, a portion of the hooded member covers a portion of the corresponding connector, thus effectively sealing the plug/connector assembly from contamination. Even more preferably, interlocking members are included on each hooded member and each corresponding connector, the interlocking members preventing accidental decoupling of the cable from the connector. The plug and connector assemblies may include means for insuring that a desired pin polarity is maintained during cable coupling.

Assignee:

Logitech International, S.A.

International Classification:

H04R 25/00

US Classification:

381380, 381381, 381322, 381328, 181130, 181135

Abstract:

An eartip that includes at least one acoustic material filled port is provided. The port and the acoustic material contained therein provide the eartip with a controlled acoustic leakage path, thus allowing the user to tailor the performance of the earphones to which the eartips of the invention are attached. The provided eartip is attachable to a standard, generic earpiece, for example through the use of interlocking members (e. g. , channel/lip arrangement). At least one port, in addition to the central opening by which the eartip is attached to the earphone, extends through the eartip. The port can have a circular cross-section, arcuate cross-section, or other shape. If desired, for example to increase the port area, the eartip can be designed with multiple ports surrounding the central opening. Within the port is an acoustic material with the desired acoustic impedance. The eartip can be coded to allow identification of the acoustic qualities of a particular eartip.

US Classification:

381 56, 381 55, 381 72, 381 74

Abstract:

A visual feedback system that activates a visual display when the sound pressure level from a headset attached to the system exceeds a preset level is provided, along with a method of using the same. The visual feedback system is interposed between the audio source and the headset and is either integral to a specific headset or coupleable to any of a variety of headsets. If a non-integral headset is used with the visual feedback system, the system is matched to the characteristics of the selected headset, for example using a selector switch or via a calibration process. During operation, the visual feedback system illuminates a display (e. g. , an LED) whenever the sound pressure level from the attached headset exceeds the preset level. The visual feedback system can be implemented using analog or digital circuitry.
