Patent number: 7740104Abstract: A non-vented shell earplug for insertion into the ear canal has multiple chambers configured as coupled acoustic resonators. Each chamber is provided with an acoustic element having inertia and resistance coupling the chamber to its neighbor to form multiple resonant chambers. The dimensions of the individual acoustic elements set the frequency response of the earplug, and determine the attenuation characteristics of the resonators. Unlike the single chamber resonator of the prior art, the multiple-resonator earplug provides attenuation in both low and high frequency segments of the noise spectrum. Additionally, the present invention teaches placing loudspeaker and/or sound sensing transducer for sound communication purposes and active noise control within the earplug, with their sound field patterns directed into a chamber for coupling to the ear canal. The use of multiple resonators enhances the high frequency communications response of the earplug.Type: GrantFiled: January 11, 2006Date of Patent: June 22, 2010Assignee: Red Tail Hawk CorporationInventors: John W.

Customized passive hearing protection earplug, use of the same and method for manufacturing the same
Patent number: 7025061Abstract: The invention relates to a passive hearing protection earplug for being worn at least in part in the ear canal (12) of a user, comprising a hard shell (20) having an elasticity of from shore D 85 to shore D 65 and pulling means (26) which are adapted for being manually operated by the user and which are provided at the outer end of said shell, said shell having an outer surface individually shaped according to the measured inner shape of the user's ear canal and outer ear (18). The shell has a size and an outer shape which are adapted to enable said shell to be manually moved, by seizing the pulling means, from a sound attenuation position into a communication position from which it is automatically returned into the attenuation position by elastic forces exerted by deformed parts of the user's ear canal and concha upon release of the pulling means. The invention also relates to a use of such an earplug and a method for manufacturing such an earplug.Type: GrantFiled: August 25, 2004Date of Patent: April 11, 2006Assignee: Phonak AGInventor: Mathias Haussmann -
Patent number: 7014010Abstract: A hearing device, which is to be applied to an area of an individual's ear, is manufactured in that the skin of that application area is first analyzed and the outer surface area of the hearing device is adapted to the characteristics of that skin, thereby taking into account the result of said analyzing. Analyzing may preferably be directed on characteristics of visual appearance, surface structure, chemical surface characteristics, mechanical behavior and state of health of such skin.Type: GrantFiled: October 17, 2001Date of Patent: March 21, 2006Assignee: Phonak AGInventor: Christoph Widmer

Patent number: 6981504Abstract: An earplug of the type that includes a soft foam body (14) and a more rigid core (16) that stiffens the body during its insertion into the ear canal, is mass produced so the front end (30) of the stiff core cannot rub along the surface of the ear canal during insertion. The core is elongated and bonded to the body, and the core has a front end (30) that is recessed from the front end (36) of the body, so the soft foam material of the body prevents the front end of the core from contacting the ear canal. The earplug can be mass produced by extruding the soft foam through an extrusion head (42), around the cores, with a long core device having been cut into the cores and with the extrusion (52) cut at locations to leave foam material forward of each core front end.Type: GrantFiled: June 16, 2004Date of Patent: January 3, 2006Assignee: Bacou-Dalloz USA Safety, Inc.Inventor: John Allen Jenkins, Jr.

Patent number: 6938621Abstract: A disposable plug has a mask with an orifice aligned at the entry into the ear canal when the plug is inserted into the ear. A sealed envelope has a leading elastic tip that extends forward of the orifice into the ear canal and a trailing reservoir that extends rearward of the orifice. A super-cooled liquid salt substantially fills the envelope. The envelope is sized to contain a sufficient quantity of the liquid salt to deliver heat to the inner ear at a predetermined temperature for a predetermined time period. A convex disk in the reservoir can be manually popped to concave after the tip of the envelope has been inserted into the ear canal to shrink the reservoir and expand the tip into deeper extension into and compliance with the ear canal and to activate solidification of the liquid salt to generate heat into the ear canal.Type: GrantFiled: August 4, 2004Date of Patent: September 6, 2005Inventors: Sareva L. Greenhaw, Lamberto Dionigi

Patent number: 6940988Abstract: A semi-permanent hearing device is disclosed which is adapted to be completely positioned within the ear canal of an individual for long-term use. The device comprises a sealing retainer substantially positioned in the bony region of the ear canal and a core assembly including a receiver assembly coaxially positioned within the sealing retainer. When the device is inserted into its completely-in-the-canal position, the core assembly extends from the sealing retainer to the cartilaginous region of the ear canal in a non-occluding fashion, thereby minimizing interference with hair and earwax production present in the cartilaginous region. In a preferred embodiment of the device, the core assembly comprises a battery assembly conforming substantially to the shape and dimensions of the battery enclosed within the assembly.Type: GrantFiled: November 25, 1998Date of Patent: September 6, 2005Assignee: InSound Medical, Inc.Inventors: Adnan Shennib, Richard C. Urso, Diep H. Ngo

Patent number: 6931142Abstract: An insert earphone which prevents a sound leakage and improves wearing comfort. An ear chip has a barrel portion and first and second annular flange portions having the shape of a parabola spreading from the top toward the middle and from the middle toward the base of the barrel portion respectively. The first annular flange portion has a smaller outer diameter than the second annular flange portion. The first annular flange portion has almost even thickness from the inner circumference to the outer circumference, and has the inner circumference neighborhood substantially formed in the shape of a sliced doughnut.Type: GrantFiled: October 28, 2002Date of Patent: August 16, 2005Assignee: Star Micronics Co., Ltd.Inventor: Isao Fushimi

Patent number: 6902029Abstract: The invention disclosed provides an improved ear protection system comprising an ear protection device and an innovative stowage device. The stowage device is capable for inconspicuously securing the ear protection device to an easily accessible entity such as an article of clothing. The system is further able to accommodate various sizes and shapes of ear protection devices at varying distances and lengths from the user's ear. Additionally incorporated in the ear protection system is a locking mechanism to control the extension and retraction of the ear protection device from th stowage device.Type: GrantFiled: October 30, 2001Date of Patent: June 7, 2005Assignee: Owl Investors of Texas, LLCInventor: Jon Weise

Patent number: RE40696Abstract: An insert earphone is provided in which a piece of foam material is used to resiliently mount a receiver within a chamber portion of a one-piece plastic housing member. The receiver has an output port extending through a central aperture of the piece of foam material and into one end of a passage defined by a tubular portion of the housing member with a damper being disposed in the other end of the passage. The tubular portion is inserted into an ear tip or other coupling device and has an enlarged diameter end section to achieve a locking action. Two such insert earphones may be coupled through cables to a junction unit and filters are provided for enhancing the drive of the earphones at high frequencies, the filters being preferably mounted in the junction unit.Type: GrantFiled: July 18, 2003Date of Patent: April 7, 2009Assignee: Etymotic Research, Inc.Inventors: Steven J. Iseberg, Donald L. Wilson
