Patent number: 11564029Abstract: The inventive subject matter is directed to headset audio systems having resonance chambers designed to improve a system's frequency response in certain ranges. Systems of the inventive subject matter include a casing that both holds a speaker driver and creates two resonance chambers. Each resonance chamber vents to ambient air outside the casing, where the length and cross-sectional areas of each vent can impact the system's frequency response. Each resonance chamber is tuned to a resonant frequency to improve the system's frequency response across a range of frequencies on either side of each chamber's resonant frequency.Type: GrantFiled: July 9, 2020Date of Patent: January 24, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Kai Lin Shen, Sheng Hung Wang, Penhao Ma, Wei-Min Liang

Patent number: 11557444Abstract: Key switches of the inventive subject matter are designed to give users the tactile feel of key switches from expensive mechanical keyboards without drawback typically associated with alternative key switches. In some embodiments, key switches described in this application are designed to function with a sheet of membrane switches, while in other embodiments, key switches of the inventive subject matter incorporate optical switching in place of membrane switching. Embodiments for use with membrane switching feature a plunger and rocker combination that prevents the pressure from a user's key press from being directly transferred to a membrane switch, thereby reducing wear and tear. In optical switching embodiments, pressing the key switch causes an actuator, e.g., come between an optical emitter/receiver pair to register a key press.Type: GrantFiled: June 8, 2020Date of Patent: January 17, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jian-Cheng Lai, Wei-Min Liang, Kuo Shou Yu

Publication number: 20220337931Abstract: Embodiments of the inventive subject matter described in this application are directed to headset audio systems that incorporate components designed to improve sound reproduction in certain ranges. For example, in some embodiments, an acoustic chamber and a venting portion are incorporated into an internal portion of a headset audio system such that the vent is configured to improve bass response. Different vent shapes and sizes can affect speaker performance. Moreover, in some embodiments, the acoustic chamber can additionally include a vent.Type: ApplicationFiled: April 16, 2021Publication date: October 20, 2022Inventors: Wei-Min Liang, Wen Ning Chang

Publication number: 20220248117Abstract: This application discloses and describes a variety of systems, methods, and devices directed to headset audio systems having acoustic chambers. Acoustic chambers of the inventive subject matter can be implemented such that the backside of a speaker diaphragm projects sound waves into an acoustic chamber. Because acoustic chambers are formed to create fixed volumes of space, this minimizes impact of those sound waves projected from the back of a speaker diaphragm that could otherwise affect sound reproduction. This new inventive audio system actually differentiates from the way diaphragms are attached which conventional speaker driver assembly doesn't, to accomplish the invention the way fixing magnets and other parts for magnetic delivering are invented to eliminate or integrated, such as frame or bracket is cancelled, chambers now use to fix magnetic parts.Type: ApplicationFiled: February 3, 2021Publication date: August 4, 2022Inventors: Chia-Ming Chang, Wei-Min Liang
