Publication number: 20240137705Abstract: A full-frequency band high quality speaker with a bar and sound tunnels includes a voice coil, magnet, diaphragm and magnetically conductive structure; the diaphragm is conical, a bridge-style bar is on the surface of at least one side of the diaphragm; the diaphragm includes at least two grooves, each horizontally radial; each groove crosses the bridge-type bar in the horizontal direction and the length direction of the groove is perpendicular to the bridge-type bar; the groove is concave on the surface of the diaphragm to form a sound tunnel. The diaphragm is changed to the current standard vibration mode, and the timbre of treble register is not bright and the timbre of bass register is not sonorous and mellow enough from the perspective of vibration, resonance and phonation. The practice proves that the improved scheme has outstanding substantive characteristics and remarkable technical progress, and has obtained obvious technical results.Type: ApplicationFiled: December 15, 2020Publication date: April 25, 2024Applicant: SUZHOU LI YUE MUSICAL INSTRUMENTS CO., LTD.Inventors: Haiou JIN, Nianbo WU, Xinxi HE, Xinzhi ZHU, Biying LI, Ping YANG

Publication number: 20240045098Abstract: A hybrid sensor for calibrating a primary active infrared (IR) sensor to more accurately locate, continuously calibrate, and conserve energy by more accurately detecting via the active IR detection is described herein. The hybrid sensor includes one or more infrared sensors and one or more time-of-flight sensors. The time-of-flight sensor may remain in a dormant state (e.g., low power or sleep mode) until the one or more infrared sensors detect an object. In response to detecting an object, the time-of-flight sensor may be activated to obtain several measurements of the object. After obtaining the measurements, the time-of-flight sensor may return to its dormant state. The hybrid sensor may use the measurements obtained by the time-of-flight sensor to calibrate the one or more infrared sensors to provide more accurate measurements on an object-by-object basis.Type: ApplicationFiled: September 12, 2023Publication date: February 8, 2024Inventors: Xiaoxiong Mo, Qiaohong Chen, Haiou Wu
