Abstract

The invention discloses a self-powered device for supplying energy for wearable equipment based on vibration power generation. The device is arranged inside the wearable equipment and comprises a receiver, a bridge rectifier, a power amplifier, a vibration source, a drumhead, a piezoelectric ceramic piece attached to the drumhead, a coil, a magnetic core, a shell, a control chip and an energy storage element; the receiver is used for receiving mechanical waves generated by the vibration source and transmitting the mechanical waves to the drumhead; the drumhead is connected with the piezoelectric ceramic piece and the coil; the front end of the coil is connected with the drumhead; electric energy generated by the coil is connected with the bridge rectifier through a wire, and the coil is used for converting the generated electric energy from alternating current into direct current; the bridge rectifier is connected with the power amplifier; an output end of the power amplifier is connected with the control chip; and the control chip is connected with the energy storage element through a wire. Some inconvenience brought by the traditional charging manner is solved, potential risks are eliminated, and a redundant self-powered mode is provided.

Description

technical field [0001] The invention relates to the field of power generation of wearable equipment, and specifically discloses a self-power supply device for powering wearable equipment based on vibration power generation. Background technique [0002] At present, the control of noise pollution in the world mainly converts noise into other forms of energy by setting up isolation or protection on its propagation path; although this reduces the harm of noise to human beings to a certain extent, it cannot completely reduce the noise. Energy is used efficiently. In recent years, many countries in the world have made many achievements in the use of noise; for example, noise power generation, noise dust removal, noise refrigeration, noise diagnosis, etc.; Power generation has important research significance and broad application prospects. [0003] The continuous work of wearable devices requires a certain amount of power support; traditional plug-in charging will bring us a lo...
