Patent number: 11966261Abstract: In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.Type: GrantFiled: September 20, 2022Date of Patent: April 23, 2024Assignee: Google LLCInventors: James Nelson Castro, Carl Alexander Cepress, Liang Ching Tseng, Darren Torrie, Frances Maria Hui Hong Kwee, Rex Pinegar Price

Publication number: 20240073589Abstract: An audio device includes a first speaker and a second speaker. A front surface of a membrane of the second speaker faces a rear surface of a membrane of the first speaker. The membrane of the first speaker moves in an opposite direction than the membrane of the second speaker when the audio device outputs audio content. This configuration maintains isobaric pressure for a back volume shared between the first speaker and the second speaker, reducing vibration of the audio device when outputting audio content.Type: ApplicationFiled: December 20, 2022Publication date: February 29, 2024Inventors: Rex Pinegar Price, Alan Ng, Calvin Bernard Shaw, Peter Mikael Mogren, Caroline Whelan, Trang Fisher, MohanRaj Manoharan

Patent number: 11743648Abstract: A headset includes a speaker, such as a side firing dipole speaker. The headset includes a front chamber that receives sound waves from a first side of the speaker and a rear chamber that receives sound waves from a second side of the speaker. A control leak channel connects the front chamber and the rear chamber. An acoustic mesh may be located within the control leak channel. The speaker configuration is configured to reduce total harmonic distortion of the speaker, particularly in ranges such as 3-6 kHz, while maintaining the broadband efficiency of the speaker.Type: GrantFiled: November 23, 2022Date of Patent: August 29, 2023Assignee: Meta Platforms Technologies, LLCInventors: Tetsuro Oishi, Rex Pinegar Price, Limin Zhou, Michael Thomas Frank, Joshua James Barr, Michael Lee Butts

Publication number: 20230239626Abstract: A coil assembly for integration into a transducer is presented. The coil assembly may include a metal bobbin assembly, a wire coil, and one or more nonconductive printed circuit board (PCB) stiffeners. A speaker that renders micro noise in an artificial reality environment for improving simulated presence is further presented. The speaker may generate a plurality of micro noises based in part on the determined state of the virtual object. The speaker may spatialize the plurality of micro noises, such that the plurality of micro noises appears to originate from the virtual object. A speaker for speaker diaphragm motion detection using optical MEMS sensors is further presented. Optical MEMS sensors are used to optically monitor displacement of one or more portions of a speaker diaphragm. The speaker may be configured to determine that a speaker diaphragm is in rocking mode and move the speaker diaphragm out of rocking mode.Type: ApplicationFiled: March 28, 2023Publication date: July 27, 2023Inventors: Limin Zhou, Chuming Zhao, Rex Pinegar Price, Mekell Jiles, Kevin Connor

Publication number: 20220321999Abstract: A dipole speaker assembly comprises a transducer section, a front volume section, and a rear volume section. The transducer section includes a frame and piezoelectric actuators coupled to the frame. The piezoelectric actuators are configured to generate an acoustic pressure wave. The transducer section includes a first side and a second side, the second side being opposite the first side. The front volume section is coupled to the first side to form a front cavity, the front volume section including an aperture from which the generated acoustic pressure wave exits the front volume section towards an ear canal of a user. The rear volume section is coupled to the second side to form a rear cavity. The generated acoustic pressure wave exiting the rear volume section cancels the generated acoustic pressure wave exiting the front volume section in the far field.Type: ApplicationFiled: February 22, 2022Publication date: October 6, 2022Inventors: Chuming Zhao, John Raymond Brodie, Rex Pinegar Price, Michael Smedegaard, Antonio John Miller, Tetsuro Oishi
