Patent number: 10080092Abstract: A method of controlling a personal acoustic device includes generating a first electrical signal responsive to an acoustic signal incident at a microphone disposed at a location on an earpiece of the personal acoustic device such that the microphone is acoustically coupled to an environment external to the earpiece. A characteristic of a transfer function based on the first electrical signal and a second electrical signal provided to a speaker in the earpiece is determined. An operating state of the personal acoustic device is determined form the characteristic of the transfer function. The operating state include a state in which the earpiece is positioned in the vicinity of an ear of a user and a second state in which the earpiece is absent from the vicinity of the ear of the user.Type: GrantFiled: October 31, 2017Date of Patent: September 18, 2018Assignee: BOSE CORPORATIONInventors: Mihir D. Shetye, Binu K. Oommen, Dale McElhone

Patent number: 10034086Abstract: A headset includes at least one ear cup having front and rear cavities separated by a driver. The cup includes a pressure equalization port coupling the front cavity to space outside the cup, the pressure equalization port having a cross-sectional area greater than 2 mm2 and being significantly longer than it is wide, providing a principally reactive acoustic impedance, such that the pressure response of the front cavity including the port to signals input via the driver may be effectively linear over a wide range of pressure levels within the front cavity.Type: GrantFiled: March 17, 2014Date of Patent: July 24, 2018Assignee: Bose CorporationInventors: Roman Sapiejewski, Mark Bergeron, Mihir D.

Publication number: 20180033419Abstract: A headphone includes an electroacoustic transducer and a support structure for suspending the transducer adjacent to a user's ear when worn by the user such that the headphone is acoustically open. A first microphone is coupled to one or more of the transducer and the support structure such that the first microphone is located in a substantially broadband acoustic null of the transducer. A processor is coupled to the headphone. The microphone receives sound pressure waves and outputs a related electronic signal to the processor. The processor uses the electronic signal to operate the transducer to reduce targeted sound pressure waves at the user's ear.Type: ApplicationFiled: July 29, 2016Publication date: February 1, 2018Applicant: Bose CorporationInventors: Mihir D. Shetye, Ole Mattis Nielsen, Ryan C. Silvestri

Patent number: 9794676Abstract: A headphone that has a support structure that is adapted to sit on a head or upper torso of a user, a first acoustic driver carried by the support structure such that the first acoustic driver is located off of an ear of the user, wherein the first acoustic driver has front and rear sides and sound is radiated from both sides of the first acoustic driver, and a structure that defines a first acoustic chamber on the front side of the first acoustic driver and with at least one opening therein, and a second acoustic chamber on the rear side of the first acoustic driver and with at least one opening therein. At low frequencies a polar pattern of the first acoustic driver behaves approximately like a dipole, and at high frequencies a polar pattern of the first acoustic driver exhibits a higher order directional pattern. A second acoustic driver can be included.Type: GrantFiled: January 12, 2016Date of Patent: October 17, 2017Assignee: Bose CorporationInventors: Mihir D. Shetye, Ryan C. Silvestri
