The application provides a detection circuit, a touchpad control system, a circuit board and an electronic device. The detection circuit comprises a sampling module, a current detection module and a voltage detection module. The current detection module collects a first electric signal of a linear motor and sends the first electric signal to a control circuit, so that the control circuit adjusts the output power of the linear motor based on the first electric signal. The voltage detection module is used for acquiring a second electric signal of the linear motor and sending the second electric signal to the control circuit, so that the control circuit determines the voltage information of the linear motor based on the second electric signal and adjusts the output power of the linear motor. The detection circuit can collect the current and voltage information of the linear motor in real time, so as to obtain the vibration state of the linear motor in real time. The collection and detection accuracy is high, and the control circuit can control and adjust the linear motor based on the vibration state, so as to avoid the problem of misjudgment of the control circuit caused by low detection accuracy.

A highly stable multi-oscillator linked flow-induced vibration power generation device includes multiple sets of power generation mechanisms distributed along a first direction, with at least two mechanisms in each set. The mechanisms within the same set are distributed along a second direction, perpendicular to the first direction. Each power generation mechanism includes a top-closed mounting cylinder containing a linear generator. The power input axis of the linear generator extends downwards and is fixedly connected to a lifting plate. A transmission rod is rotatably connected to the lower surface of the lifting plate, and an oscillator is fixedly connected to the lower end of the transmission rod. The oscillator is parallel to the fluid surface and immersed in the fluid. This invention provides a highly stable multi-oscillator linked flow-induced vibration power generation device and method. It can adjust the oscillator according to the fluid flow velocity, avoiding excessively high vibration amplitude and frequency when the fluid flow velocity is too high by changing the oscillator's water-facing area, thus protecting the oscillator and other structures.
