Patent number: 11368780Abstract: A bone conduction earphone includes an earphone body configured to attach to an auricle of a human body and transmit an audio vibration signal and an ear hook configured to hook on the auricle. A first end of the ear hook is fixedly connected with the earphone body. A second end of the ear hook extends between the auricle and a head of the human body. The second end of the ear hook extends along the auricle and laterally deviates from the earphone body. In a natural state, a lateral distance between the earphone body and an extending end of the ear hook is less than a lateral distance from a front surface of the auricle to a back surface of the auricle. When the bone conduction earphone is worn, the earphone body and the ear hook clamp the auricle.Type: GrantFiled: December 6, 2021Date of Patent: June 21, 2022Assignee: SHENZHEN XINWANHONG TECHNOLOGY CO., LTD.Inventor: Yuliang Kong

Patent number: 11330374Abstract: A head-gear mounted bone-conducting microphone includes a housing attachable to a helmet and a transducer housed in a flexible shroud. The shroud is attached to the housing. A resilient material is disposed within the shroud. A void is provided between the resilient material and the housing to prevent the transducer from transmitting vibrations directly from the housing to the transducer. This configuration allows the microphone to effectively mechanically isolate the minuscule vibrations associated with speech from the enormous vibrations associated with most loud environments (machinery, equipment, transportation, aircraft, tanks, construction, sporting events, etc.).Type: GrantFiled: October 20, 2021Date of Patent: May 10, 2022Assignee: JLI Electronics, Inc.Inventors: Jody DiLorenzo, Peter L.

Patent number: 11240588Abstract: Provided is an ear-hole open type sound reproducing apparatus which can obtain good sound quality over a wide band while adopting a bone conduction system. A first equalizer 303 removes a high range component which is difficult to be reproduced by a vibration speaker 301 and is hard to be conveyed by bone conduction. Then, the vibration speaker 301 outputs the sound over a low range to a middle range by bone conduction sound. By equalizing processing of the first equalizer 303, it is also possible to reduce sound leakage of the high range. On the other hand, a second equalizer 304 removes components over the low range to the middle range. Then, an air conduction speaker 302 outputs high quality sound of the high range component by air conduction sound.Type: GrantFiled: December 28, 2016Date of Patent: February 1, 2022Assignee: SONY CORPORATIONInventors: Masataka Ozawa, Kazuhiro Sekine, Jo Kamada
