Abstract: A display module and an electronic device are provided. The display module includes an acoustic-electrical conversion layer, first electrodes, second electrodes, and third electrodes. The first electrodes and the third electrodes are provided on two opposite sides of the acoustic-electrical conversion layer, and second electrodes are provided at intervals on the two opposite sides of the acoustic-electrical conversion layer. In a thickness direction of the acoustic-electrical conversion layer, projections of the first electrodes and projections of the third electrodes are arranged at intervals, and one of the first electrodes or one of the third electrodes is disposed corresponding to at least two of the second electrodes.

Abstract: A camera module includes a lens assembly, a module bracket, a first limit member, a first deformable member, and a second deformable member. The lens assembly is rotatably connected to the module bracket. The first limit member is fastened to the lens assembly or the module bracket. The first and second deformable members are both electro-deformable members. The first and second deformable members are respectively disposed on two opposite sides of the first limit member. When the lens assembly rotates with respect to the module bracket along a first direction, the first deformable member deforms, so that a first rotation angle of the lens assembly is measured. When the lens assembly rotates with respect to the module bracket along a second direction, the second deformable member deforms, so that a second rotation angle of the lens assembly is measured, the second direction being opposite to the first direction.

Abstract: A circuit control apparatus includes: a charging control module, a circuit switching module, a capacitance detection module, a first change-over switch, and a first polar plate. The first change-over switch includes a first common terminal, a second terminal, and a third terminal. The first polar plate is electrically connected to the first common terminal. The charging control module is electrically connected to the second terminal. The capacitance detection module is electrically connected to the third terminal.
