A sound pickup device for effectively improving English listening and speaking teaching

Abstract

The invention discloses a sound pickup device for efficiently improving English listening and speaking teaching, relates to the technical field of radio microphones, and solves the problem that the existing microphone cannot be operated with one hand when adjusting the height, which affects the teaching efficiency of the classroom. A sound pickup device for efficiently improving English listening and speaking teaching comprises a positioning cylinder; the adjusting wheel is rotatably connected to the inside of a fixed seat, and the cylinder body of the positioning cylinder passes through the inside of the adjusting wheel. When the device is in use, the use height of the microphone clip can be adjusted directly by rotating the adjustment rod, and the adjusted use height of the microphone clip can be automatically locked, thereby changing the use height of the radio microphone, and the microphone clip can be freely rotated in the adjustment dome cover Change the angle of use, the adjustment of the device can be adjusted with one hand to complete the operation, the adjustment is fast, the use is simple, and the teaching in class is not delayed.

Description

technical field [0001] The invention belongs to the technical field of radio microphones, and more particularly, relates to a sound pickup device for efficiently improving English listening and speaking teaching. Background technique [0002] In traditional English classrooms, the way teachers ask questions and students answer cannot guarantee the full learning efficiency of every student. Therefore, in the current English teaching classroom, microphones are used to record or amplify the teacher's teaching, so as to facilitate students to review and use after class. , which can effectively consolidate the content of the class. [0003] For example, in the patent with the application number: CN201710417964.X, a teaching quality evaluation method and system based on classroom student behavior analysis are disclosed. The video image, the voice signal of the teaching teacher, the noise signal of the classroom environment and the amount of electromagnetic radiation are transmitt...
