Abstract: The present disclosure relates to an earphone including 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 a projection of the ear hook on the user's sagittal plane includes a first curve that has 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 user's sagittal plane, and the upper vertex of the ear hook is the highest point of an inner contour of the ear hook along a vertical axis of the user.

Abstract: 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.

Abstract: The present disclosure provides an open earphone comprising: a sound producer including a transducer and a housing accommodating the transducer; and an ear hook, the ear hook including a first portion and a second portion; wherein the ear hook and the sound producer form a first projection on a first plane, the first projection including an outer contour, a first end contour, an inner contour and a second end contour, and the outer contour, the first end contour, the second end contour and a tangent segment connecting the first end contour and the second end contour jointly define a first closed curve.

Abstract: The present disclosure provides an open earphone comprising: a sound production component including a transducer and a housing accommodating the transducer; and an ear hook including a first portion of the ear hook and a second portion of the ear hook. The first portion of the ear hook is hung between an auricle and a head of a user, and the second portion of the ear hook extends towards a side of the auricle away from the head and connects with the sound production component to place the sound production component in a position near an ear canal but not blocking the ear canal, the housing and the first portion of the ear hook clamp the auricle of the user, and provide a clamping force in a range of 0.03 N to 1 N to the auricle of the user.

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°.

Abstract: 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.

Abstract: 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.

Abstract: A pose determining method, which may be applied to the field of photographing and image processing, includes: obtaining a target image, where the target image includes a target parking space mark and a target parking space line, and a target parking space corresponding to the target parking space mark includes the target parking space line; and determining pose information based on the target parking space mark and the target parking space line. The pose information indicates a corresponding pose of a terminal during photographing of the target image. According to the pose determining method, the pose information may be determined based on the target parking space mark and the target parking space line, to implement positioning.
