Disclosed are a linear actuator control circuit capable of achieving accurate positioning, and a linear actuator. The control circuit comprises a motor driving circuit, a master control circuit and at least one intermediate switch; by disposing the intermediate switch between two ends of a stroke of the linear actuator, the intermediate switch can be triggered when the linear actuator runs to the intermediate switch; after the master control circuit receives information of the intermediate switch, running of the linear actuator is stopped, so that the linear actuator stops running when accurately running to a state that the intermediate switch is triggered, and then, accurate positioning of a sliding block on the linear actuator is achieved.

The present invention discloses a sofa USB socket including: a USB female socket including a tongue core, wherein the tongue core includes 5 pins, and the fifth pin is an ID pin; and a USB circuit including a power circuit, a filter circuit, a control chip and a buck chopper circuit, wherein the buck chopper circuit includes a transistor, and the ID pin is electrically connected with the transistor. When an external USB male plug is inserted into the USB female socket, the power circuit supplies power to the USB female socket; when the USB female socket is in an unloaded state, the fifth pin is suspended, the control chip enters a sleep state, and the USB female socket has no output voltage, which greatly reduces the no-load energy consumption, thereby being beneficial to extending the endurance time and the service life of a power supply battery.
