The control module outputs a control signal to control the first image capture module and the second image capture module to be in a working state in a time-sharing manner. A first signal interface is electrically connected to the first node. The first optimization unit is electrically connected between the first node and the first image capture module, and the second optimization unit is electrically connected between the first node and the second image capture module. The first optimization unit is configured to ensure the smoothness of a curve of a first image signal corresponding to a first image captured when the first image capture module is in the working state, and the second optimization unit is configured to ensure the smoothness of a curve of a second image signal corresponding to a second image captured when the second image capture module is in the working state.

A multiplexing circuit and a mobile terminal, related to the field of electronic and communications technologies, that resolve a problem that product costs are high when a mobile phone uses an integrated switch. In the multiplexing circuit, a first switch circuit transmits, to a first signal transmission end, a right sound channel audio signal provided by a right sound channel transmission end. A second switch circuit transmits, to a second signal transmission end, a left sound channel audio signal provided by a left sound channel transmission end. Signal transmission between the first signal transmission end and a first output end and signal transmission between the second signal transmission end and a second output end are implemented by using a third switch circuit. The first switch circuit includes a first transistor and a first constant voltage control circuit.

Multiplexing circuit and mobile terminal

An electronic device includes a signal trigger circuit, a flat-motor drive circuit, and a flat motor. The signal trigger circuit sends a starting instruction to the flat-motor drive circuit for instructing to start the flat motor. A processor of the flat-motor drive circuit sends a first triggering instruction to a voltage processing circuit of the flat-motor drive circuit after receiving the starting instruction. The voltage processing circuit provides a first working voltage Vto the flat motor after receiving the first triggering instruction, and provides a second working voltage Vto the flat motor after a first time period. V&#x3c;V&#x2264;V, Vis a rated voltage value of the flat motor, and Vis a maximum forward voltage value that the flat motor can bear when the flat motor is started.
