A lens prism module relates to the field of shooting equipment and includes a fixed base, a rotating base, a prism, and a driving assembly. The rotating base includes rotating shafts connected with the fixed base. The rotating base is recessed to form rotating grooves. A bottom portion of each rotating groove includes supporting surface structures disposed obliquely with respect to an axis of the rotating shafts. One end of each rotating shaft is of a curved surface structure. Each curved surface structure is tangent to a corresponding supporting surface structure for realizing rotation of the rotating base, which reduce resistance of rotation, reduces a driving force for driving rotation of the rotating base, so that the lens prism module responds quickly when performing an optical image stabilization function. Meanwhile, it limits shaking of the rotating shafts and the rotating shafts are stably rotatably connected with the rotating base.

A bi-stable solenoid includes a housing, a wire coil, a permanent magnet, an armature, a pin, and a spring. The wire coil is arranged within the housing. The armature is slidably arranged within the housing and is moveable between a first armature position and a second armature position. The pin at least partially extends out of the housing and is slidably engaged by the armature. The spring is biased between the armature and the pin. When the pin encounters an intermediate position between a retracted position and an extended position due to the pin engaging an obstruction, the spring is configured to maintain a biasing force on the pin until the obstruction is removed.

A photographing apparatus and an electronic device are provided. The photographing apparatus includes a frame assembly, a first movement assembly, first support members, a second movement assembly, second support members, and a lens module. The frame assembly is provided with a receiving cavity. The first movement assembly is suspended in the receiving cavity, and a movement cavity is provided inside the first movement assembly. The first support members are each arranged at least partially in a respective first movement groove and abut against the first movement assembly and the frame assembly. The first movement grooves adapted to the first movement assembly and the second movement grooves adapted to the second movement assembly are provided such that the photographing apparatus is of a compact structure on condition that the lens module can rotate about the first axis of rotation and/or the second axis of rotation.

A lens driving device related to the field of driving devices and includes a lens assembly and a driving module for driving the lens assembly to move. The driving module includes a first driving module and a second driving module. The lens assembly is accommodated in the first driving module. The second driving module is sleeved on one side of the first driving module away from the lens assembly. The lens assembly is driven by the first driving module and the second driving module that realize movement in multiple different directions, so the lens assembly accommodated in the first driving module realizes movement in multiple directions, thereby achieving good image stabilization effect.

An actuator has a first stator with four first poles, a second stator with four second poles aligned with the four first poles, at least one permanent magnet between the first stator and the second stator, four armatures positioned at terminal ends of the aligned four first poles and four second poles and coils wrapped around the first stator and the second stator. A controller selectively applies current to the coils to cause flux created by the at least one permanent magnet to traverse through selective poles of the first stator and the second stator to selectively alter air gap sizes associated with the four armatures.

An electric element includes a substrate including a resin layer and a first conductive body, and a magnet. The substrate includes a first principal surface facing the magnet. The first conductive body includes a coil portion having a winding axis orthogonal to the first principal surface and located on a side closest to the first principal surface. The coil portion includes a continuous coil conductor including a first coil surface facing the first principal surface and a second coil surface opposite to the first coil surface. The coil conductor has a non-uniform thickness in a winding axis direction varying a distance between the first and second coil surfaces, and a difference of maximum and minimum values of distance between the first coil surface and the first principal surface is smaller than a difference of maximum and minimum values of distance between the second coil surface and the first principal surface.

An electromagnetic actuator including a coil; a non-movable part constituted by a magnetic substance and disposed on one side relative to the coil; and a movable part including a permanent magnet on the other side relative to the coil. Applying a current to the coil alternately generates first and third driving forces to move the magnet and the movable part to one and the other sides in a first direction relative to the coil and the non-movable part. As the movable part moves from a neutral position to the one side in the first direction, a portion of the magnet positioned on the one side in the first direction relative to the first end of the first non-movable part gradually enlarges and is magnetically attracted toward the non-movable part. As the movable part moves from the neutral position to the other side in the first direction, a portion of the magnet positioned on the other side in the first direction relative to the second end of the first non-movable part gradually enlarges and is magnetically attracted toward the non-movable part.
