Patent number: 9338538Abstract: A microphone system implements multiple microphones on a single base. To that end, the microphone system has a base, and a plurality of substantially independently movable diaphragms secured to the base. Each of the plurality of diaphragms forms a variable capacitance with the base and thus, each diaphragm effectively forms a generally independent, separate microphone with the base.Type: GrantFiled: April 26, 2013Date of Patent: May 10, 2016Assignee: INVENSENSE, INC.Inventors: Jason W. Weigold, Kieran P. Harney

Patent number: 8995693Abstract: A microphone system has a base coupled with first and second microphone apparatuses. The first microphone apparatus is capable of producing a first output signal having a noise component, while the second microphone apparatus is capable of producing a second output signal. The first microphone apparatus may have a first back-side cavity and the second microphone may have a second back-side cavity. The first and second back-side cavities may be fluidly unconnected. The system also has combining logic operatively coupled with the first microphone apparatus and the second microphone apparatus. The combining logic uses the second output signal to remove at least a portion of the noise component from the first output signal.Type: GrantFiled: December 12, 2012Date of Patent: March 31, 2015Assignee: Invensense, Inc.Inventors: Kieran P. Harney, Jason W. Weigold, Gary W. Elko

Patent number: 8934648Abstract: A microphone includes a diaphragm assembly supported by a substrate. The diaphragm assembly includes at least one carrier, a diaphragm, and at least one spring coupling the diaphragm to the at least one carrier such that the diaphragm is spaced from the at least one carrier. An insulator (or separate insulators) between the substrate and the at least one carrier electrically isolates the diaphragm and the substrate.Type: GrantFiled: April 1, 2013Date of Patent: January 13, 2015Assignee: Invensense, Inc.Inventor: Jason W.

Patent number: 8828773Abstract: A method of forming a microphone forms a backplate, and a flexible diaphragm on at least a portion of a wet etch removable sacrificial layer. The method adds a wet etch resistant material, where a portion of the wet etch resistant material is positioned between the diaphragm and the backplate to support the diaphragm. Some of the wet etch resistant material is not positioned between the diaphragm and backplate. The method then removes the sacrificial material before removing any of the wet etch resistant material added during the prior noted act of adding. The wet etch resistant material then is removed substantially in its entirety after removing at least part of the sacrificial material.Type: GrantFiled: November 6, 2012Date of Patent: September 9, 2014Assignee: Invensense, Inc.Inventor: Jason W.

Patent number: 8358793Abstract: A microphone is formed to have a diaphragm that is configured to improve signal to noise ratio. To that end, the microphone has a backplate having a hole therethrough, and a diaphragm movably coupled with the backplate. The diaphragm has a bottom surface (facing the backplate) with a convex portion aligned with the hole in the backplate.Type: GrantFiled: March 14, 2011Date of Patent: January 22, 2013Assignee: Analog Devices, Inc.Inventor: Jason W.

Patent number: 8169042Abstract: A method of forming a microphone having a variable capacitance first deposits high temperature deposition material on a die. The high temperature material ultimately forms structure that contributes to the variable capacitance. The method then forms circuitry on the die after depositing the deposition material. The circuitry is configured to detect the variable capacitance.Type: GrantFiled: July 28, 2010Date of Patent: May 1, 2012Assignee: Analog Devices, Inc.Inventors: Jason W. Weigold, John R. Martin, Timothy J. Brosnihan

Patent number: 8111871Abstract: A microphone has a movable diaphragm having a rest position, a stationary portion, and a set of springs movably coupling the diaphragm and the stationary portion. The diaphragm and stationary portion are spaced a first distance when the diaphragm is in the rest position. When not in the rest position, however, the diaphragm and stationary portion are capable of being spaced a second distance, which is greater than the first distance. Despite the change in distance, the diaphragm still is capable of returning the space from the second distance to the first distance when the diaphragm returns to the rest position.Type: GrantFiled: January 17, 2008Date of Patent: February 7, 2012Assignee: Analog Devices, Inc.Inventors: Xin Zhang, Michael W.
