Abstract: The present disclosure provides a loudspeaker assembly and an electronic device, relating to the technical field of electronic devices, so as to solve the problems of single sound effect and lack of good sound effect. The loudspeaker assembly includes a first housing, a second housing, a loudspeaker vibrator and an adjusting mechanism. The first housing and the loudspeaker vibrator form a first cavity, and the second housing and the loudspeaker vibrator form a second cavity. The adjusting mechanism includes a driving mechanism and a filling part. The driving mechanism drives the filling part to move, so as to change the volume of the filling part extending into the second cavity.

Abstract: A rotary earhanger structure of a wireless earphone includes an earhanger unit and a movable connection sleeve rotationally connected therewith. One end of the earhanger unit includes a first inclined surface portion extending obliquely in a preset rotational direction. The movable connection sleeve has a second inclined surface portion cooperatively connected with the first inclined surface portion. The movable connection sleeve is connected with an elastic member for driving the movable connection sleeve in a direction close to the earhanger unit. The external force rotates the earhanger unit in the preset rotating direction to adjust the wearing angle. When the earhanger unit is not subjected to the external force, the movable connection sleeve moves in the direction close to the earhanger unit under the force of the elastic member, so that the automatic reset function after the earhanger rotation is realized, thereby simplifying user operation and improving user experience.

Abstract: A high-acoustic-resistance piston motion loudspeaker disclosed in the present disclosure belongs to the field of sound-electricity conversion. The loudspeaker includes a substrate, a driving assembly, a vibrating diaphragm, a connecting assembly and a vibration cavity. The connecting assembly is not coplanar with the vibrating diaphragm, which is of a concealed connecting structure. The driving assembly is configured to drive the vibrating diaphragm to generate a piston motion. The vibrating diaphragm is located in the vibration cavity, and a displacement range of the vibrating diaphragm in a perpendicular direction is within a height range of the vibration cavity formed by a supporting structure extending in a thickness direction of a base, so as to achieve purposes of reducing air leakage and improving a sound pressure level in a working process of the loudspeaker.

Abstract: The present application relates to methods, apparatuses, computer devices, and storage mediums for generating an aerial photographing path for a UAV. A method according to an embodiment includes acquiring an inputted aerial photographing landmark; obtaining a UAV aerial photographing safe space according to the aerial photographing landmark; constructing a viewing angle quality scalar field of the aerial photographing landmark; and generating an aerial photographing path set in the UAV aerial photographing safe space according to the viewing angle quality scalar field.

Abstract: A hand protection method is provided that detects hand self-motion information and relative motion information between the hand and surrounding objects. The method also contemplates evaluating a risk level of the hand injured by surrounding objects according to the detected self-motion information and the detected relative motion information. An alarm is sounded if the risk rises above a predetermined risk level.

Abstract: This invention proposes a new method and software to generate a path with good quality for aerial video shooting in large scale scenes. Using a coarse 2.5D model of a scene, this path generation method consists of several steps: first the user is expected to specify a set of landmarks and designate a superset of key-views for each landmark; our system then automatically generates and evaluates a variety of local camera moves for observing each landmark, which are smooth and collision-free; then automatically determines the optimal order in which the landmarks should be visited, chaining the local camera moves into a single continuous trajectory. Thus, users are able to focus on specifying the visual content that should be captured by the aerial video, rather than on the difficult lower level aspects of designing and specifying the precise drone and camera motions.
