A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Systems and methods for suppressing sound leakage

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. In a wearing state, a portion of the ear hook is hung between an auricle and a user's head, and the other portion of the ear hook extends towards a side of the auricle away from the head and connects to 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 is provided with a sound outlet on an inner side surface towards the auricle for guiding a sound generated by the transducer out of the housing and to the ear canal, and a ratio of an area of the sound outlet to an area of the inner side surface is between 0.015 and 0.25.

Open earphones

The present disclosure provides an earphone comprising a sound production component and a suspension structure. The sound production component includes a diaphragm and a housing.

The sound production component and the first portion of the ear hook clamp the auricle in a wearing state.

Headphones

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°.

The present disclosure provides a headphone including a sound production component and an ear hook. The ear hook and the sound production component form a first projection on a user's sagittal plane. In a non-wearing state, an inner contour, a first end contour, a second end contour of the first projection, and a tangent segment connecting the first end contour and the second end contour jointly define a first closed curve. A first area of the first closed curve ranges 300 mm-500 mm. A portion of the inner contour corresponding to the ear hook includes a first curve. The first curve has an extremum point in a first direction 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 present disclosure relates to acoustic technology, in particular to an earphone including a sound generation portion. The sound generation portion includes a transducer and a housing for accommodating the transducer. The earphone further includes an earhook. The earhook includes a first portion and a second portion. The first portion may be hung between an auricle and the head of a user, and the second portion may be connected to the first portion, extends toward an anterolateral side of the auricle, and may be connected to the sound generation portion. The sound generation portion may be fixed near an ear canal without blocking an opening of the ear canal. In at least one frequency range, when an input current of the transducer does not exceed 35.3 mA, a maximum sound pressure that the sound generation portion is able to provide to the ear canal may not be smaller than 75 dB.

An unmanned aerial vehicle includes a central body, a plurality of arms extendable from the central body, and one or more joints. Each of the plurality of arms is configured to support one or more propulsion units, and is configured to transform between (1) a flight configuration in which the arm is extending away from the central body and (2) a compact configuration in which the arm is folded against the central body. Each joint is configured to couple one arm to the central body. At least one of the one or more joints includes an elastic element configured to cause at least one of the plurality of arms to automatically retract when the at least one of the plurality of arms is reversibly folded to a first predetermined state, and automatically extend when the at least one of the plurality of arms is reversibly extended to a second predetermined state.
