Abstract

The invention discloses a portable microphone with electric power supplied by voice vibration. The portable microphone comprises a casing, an audio cavity arranged on the casing, a microphone module arranged on the outer side of the audio cavity and manufactured on the basis of a mini-type electromechanical system technology and a power module supplying power for the microphone module, wherein the power module comprises a moving-coil sound transmission power generation device for converting voice into induced current, a rectifying filtering circuit for converting the induced current input by the moving-coil sound transmission power generation device into direct current, and a power storage module for storing the direct current input by the rectifying filtering circuit and allowing the microphone module to use the direct current; the moving-coil sound transmission power generation device is arranged inside the audio cavity. Compared with the prior art, the portable microphone with electric power supplied by voice vibration, provided by the invention, has the advantages of light weight, low power consumption and portability, and dry batteries, button batteries and other batteries are unnecessary.

Description

technical field [0001] The invention relates to a portable microphone, in particular to a portable microphone with power provided by sound vibration. Background technique [0002] The wireless microphone is composed of several pocket transmitters (can be put in the pocket, the output power is about 0.01W) and a centralized receiver, which is suitable for various occasions such as stage and podium. Currently, wireless microphones connected to multimedia are heavy, and will become even heavier with batteries installed. When a lecturer gives a lecture, he usually uses one hand to grasp the microphone, and the other hand is used to make gestures, write on the blackboard, and operate a mouse. Instructors can become very tired during longer lectures. If the lecturer accidentally drops the microphone on the ground, the microphone will break. In addition, ordinary wireless microphones consume a lot of power, and a new pair of batteries can last less than a day. [0003] In view ...
