Patent number: 8280082Abstract: The present invention relates to a microphone that includes a housing and a diaphragm and backplate located with the housing. The housing has a sound port for receiving the sound. The diaphragm undergoes movement relative to the backplate, which it opposes, in response to the incoming sound. The backplate has a charged layer with a first surface that is exposed to the diaphragm and a second surface opposite the first surface. The backplate further includes a conductor for transmitting a signal from the backplate to electronics in the housing. The conductor faces the second surface of the charged layer. To minimize the charge degradation created by contact with or infiltration of foreign materials, the first surface, the second surface, or both surfaces of the charged layer includes a protective layer thereon.Type: GrantFiled: March 17, 2010Date of Patent: October 2, 2012Assignee: Sonion Nederland B.V.Inventors: Aart Z. van Halteren, Roelof A. Marissen, Michel Bosman, Dion I. de Roo, Raymond Mögelin, Michel de Nooij

Patent number: 7792315Abstract: A silicon-based transducer assembly coupled to a movable structure in a hearing instrument. The transducer assembly includes at least one microphone chip and an ASIC having multiple integrated components such as any combination of a DSP, an A/D converter, an amplifier, a filter, or a wireless interface. The movable structure may be a battery access door, a volume dial, a switch, or a touch pad. A protection strip can be disposed across the battery access door to prevent debris from clogging the silicon-based transducer assembly. The transducer assembly may also include an array of microphone chips to achieve adaptive beam steering or directionality. When equipped with a wireless interface, the hearing instrument wirelessly communicates with another hearing instrument or with a network.Type: GrantFiled: November 28, 2006Date of Patent: September 7, 2010Assignee: Epcos AGInventors: Matthias Müllenborn, Aart Z. van Halteren

Patent number: 6169810Abstract: An electroacoustic transducer of the electret type, having a backplate situated above a diaphragm, with the backplate being provided with spacers. The diaphragm is clamped on a frame-shaped carrier located at an underside of the diaphragm. The carrier is provided with supporting portions which are vertically aligned with the spacers. In one embodiment, supporting posts are formed on the supporting portions to allow the carrier to rest on a case bottom. The resulting electroacoustic transducer can be easily assembled with a reduced risk of damage.Type: GrantFiled: April 15, 1997Date of Patent: January 2, 2001Assignee: Microtronic Nederland, B.V.Inventors: A.

Patent number: 5255246Abstract: An electroacoustic transducer of the electret type, comprising a case (101) having an opening (102) via which the interior of the case communicates with the surroundings; a backplate (105) and a diaphragm (107) arranged opposite the backplate in the case, the surface of the backplate being provided at least partly with an electret material (106) and at least a part of the surface of the diaphragm being provided with an electrically conductive layer (110); and an annular element (109) for securing the circumference of the diaphragm to the inside wall of the case. According to the invention, the parasitic capacity between the backplate (105) and the annular element (109) is eliminated in that the backplate and the annular element are both electrically connected with the case and thereby have the same potential as the case. This also provides production-technical advantages.Type: GrantFiled: September 17, 1992Date of Patent: October 19, 1993Assignee: Siemens Nederland N.V.Inventor: Aart Z. van Halteren

Patent number: 4567382Abstract: An electret transducer and a method for making same. A multiple support between a diaphragm plate and a backplate is provided by a plurality of relatively small spacing disks made of an electrically insulating material and which as separate posts are fixedly attached on the upper surface of the backplate. Such spacing disks are conveniently and accurately punched from a foil of dielectric material which is held opposite and above the backplate, whereafter the spacing disks thus formed are attached on the backplate.Type: GrantFiled: April 10, 1984Date of Patent: January 28, 1986Assignee: Microtel B.V.Inventor: Aart Z. van Halteren
