Publication number: 20250097553Abstract: The present document describes a camera module with electrostatic discharge (ESD) protection. In particular, the camera module includes a lightning rod structure, which guides an ESD current to a safe location (e.g., system ground) when a lens retainer of the camera module is hit by an ESD spark. Due to the impact on camera focus tuning and the risk of audio rub and buzz, the lightning rod structure does not physically touch the lens retainer. As such, a gap separates the lightning rod structure from the lens retainer. When the lens retainer is stressed by an ESD spark, the gap is broken down and a conductive path is established to guide the ESD current to the safe location through the lightning rod structure. In this way, the ESD current flows along a controlled path instead of jumping to arbitrary locations, which protects nearby susceptible circuitry.Type: ApplicationFiled: August 1, 2022Publication date: March 20, 2025Applicant: Google LLCInventors: Jingyu Huang, Liang Ching Tseng, Tsung-Dar Cheng, Alexander P.

Publication number: 20240192734Abstract: This application is directed to a display assistant device that acts as a voice-activated user interface device. The display assistant device includes a base, a screen and a speaker. The base is configured for sitting on a surface. The screen has a rear surface and is supported by the base at the rear surface. A bottom edge of the screen is configured to be held above the surface by a predefined height, and the base is substantially hidden behind the screen from a front view of the display assistant device. The speaker is concealed inside the base and configured to project sound substantially towards the front view of the display assistant device.Type: ApplicationFiled: December 18, 2023Publication date: June 13, 2024Applicant: Google LLCInventors: James Castro, Marc Davidson, Chih-Min Chien, Daniel Corbalan, Carl Cepress, Liang Ching Tseng

Publication number: 20240184340Abstract: 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: ApplicationFiled: December 18, 2023Publication date: June 6, 2024Applicant: Google LLCInventors: James Nelson Castro, Carl Alexander Cepress, Liang Ching Tseng, Darren Torrie, Frances Maria Hui Hong Kwee, Rex Pinegar Price
