Publication number: 20240147114Abstract: The present disclosure provides an earphone comprising a sound production component and an ear hook. In a wearing state, the ear hook is configured to place the sound production component at a position near an ear canal but not blocking the ear canal. An inner contour of the ear hook's projection on a user's sagittal plane includes a first curve having an extremum point in a first direction. The first direction is perpendicular to a long-axis direction of a projection of the sound production component on the sagittal plane. The extremum point is located behind a projection point of an upper vertex of the ear hook on the sagittal plane, and the upper vertex is a highest point of an inner contour of the ear hook along the user's vertical axis. An inclination angle of the long-axis direction relative to a horizontal direction is within a range of 13°-21°.Type: ApplicationFiled: November 2, 2023Publication date: May 2, 2024Applicant: SHENZHEN SHOKZ CO., LTD.Inventors: Lei ZHANG, Peigeng TONG, Guolin XIE, Yongjian LI, Jiang XU, Tao ZHAO, Duoduo WU, Ao JI, Xin QI, Zeying ZHENG, Haofeng ZHANG

Publication number: 20240147118Abstract: An earphone which includes a sound production component and an ear hook may be provided. The sound production component includes a transducer and a housing accommodating the transducer. A first portion of the ear hook is hung between an auricle and the head of a user, and a second portion extends toward a side of the auricle away from the head and is connected to the sound production component. In a non-wearing state, the ear hook and the sound production component form a first projection on a first plane; in a wearing state, the ear hook and the sound production component form a second projection on a sagittal plane of a human body. Each of the first projection and the second projection includes an outer contour, a first end contour, an inner contour, and a second end contour.Type: ApplicationFiled: November 15, 2023Publication date: May 2, 2024Applicant: SHENZHEN SHOKZ CO., LTD.Inventors: Jiang XU, Zeying ZHENG, Haofeng ZHANG

Publication number: 20240147117Abstract: The present disclosure provides an earphone, comprising a sound production component and an ear hook configured to place the sound production component near an ear canal but not blocking an ear canal opening. An inner contour of a projection of the ear hook on a user's sagittal plane includes a first curve having an extremum point in a first direction. The first direction is perpendicular to a long-axis direction of a projection of the sound production component. The extremum point is located behind a projection point of an upper vertex of the ear hook on the sagittal plane. The upper vertex is a highest point of an inner contour of the ear hook along the user's vertical-axis. A housing of the sound production component and a first portion of the ear hook clamp the user's auricle and provide a clamping force of 0.03 N?1 N to the auricle.Type: ApplicationFiled: November 10, 2023Publication date: May 2, 2024Applicant: SHENZHEN SHOKZ CO., LTD.Inventors: Jiang XU, Zeying ZHENG, Haofeng ZHANG

Publication number: 20240073583Abstract: The present disclosure discloses an earphone. The earphone may include a hook-shaped component, a connecting component, and a holding component. When the earphone is in a wearing state, the hook-shaped component may be configured to hang between a rear side of an ear of a user and a head of the user. The holding component may be configured to contact a front side of the ear. The connecting component may be configured to connect the hook-shaped component and the holding component and extend from the head to an outside of the head to cooperate with the hook-shaped component to provide the holding component with a pressing force on the front side of the ear.Type: ApplicationFiled: November 9, 2023Publication date: February 29, 2024Applicant: SHENZHEN SHOKZ CO., LTD.Inventors: Zeying ZHENG, Jiang XU, Yonggen WANG, Haofeng ZHANG, Gan LAI, Chong WANG, Liwei WANG, Ruixin HAN, Lei ZHANG, Junjiang FU

Patent number: 11725638Abstract: Electroaerodynamic devices and their methods of operation are disclosed. In one embodiment, ions are formed by dielectric barrier discharge using a time varying voltage differential applied between a first electrode and a second electrode. The ions are then accelerated in a downstream direction using a second voltage differential applied between a third electrode and the first and/or second electrodes, where the third electrode is located down stream from the first and second electrodes. The ions may then collide with naturally charged molecules and/or atoms within a fluid to accelerate the fluid in the downstream to create an ionic wind and an associated thrust.Type: GrantFiled: January 28, 2020Date of Patent: August 15, 2023Assignee: Massachusetts Institute of TechnologyInventors: Steven Barrett, Haofeng Xu, Yiou He
