Abstract

The invention discloses an intelligent device for English teaching. The intelligent device for the English teaching comprises a pronunciation collector and an analysis module. The pronunciation collector comprises a housing. The housing is internally provided with a backboard and a vibrating diaphragm. The edge of the vibrating diaphragm is connected with the housing. The inner wall of the housingis provided with a plurality of first grooves. The first grooves are internally provided with a first worm. The first worm is connected to a first motor through a first worm wheel. The top end of thefirst worm is in the shaft connection with a clamping block. The clamping block is used for clamping and fixing the vibrating diaphragm. The top of the vibrating diaphragm is provided with a top plate. The top plate is fixed in the housing. The top plate and the vibrating diaphragm are alternately installed. The top plate is provided with a plurality of through holes. A second worm is inserted and connected in the through holes. The second worm is connected to a second motor through a second worm wheel. The bottom of the second worm is in the shaft connection with a first metal spring sheet.The surface of the first metal spring sheet is provided with a flexible buffer layer. The intelligent device for the English teaching is capable of improving the deficiency of the prior art, improvingthe accuracy of the collector for collecting the pronunciation, and improving the judgment precision of the analysis module.

Description

technical field [0001] The invention relates to an English teaching device, in particular to an intelligent device for English teaching. Background technique [0002] In the process of English teaching, oral English teaching for students is a very important project. Traditional oral English teaching is usually through students reading aloud, and the teacher evaluates and corrects on the spot. Although this teaching method is effective, but because it is one-to-one teaching, the teaching efficiency is low. Chinese invention patent application CN106940939A discloses an auxiliary device for oral English teaching, which collects students' reading audio through a collector, and evaluates and guides students' oral pronunciation through an analysis module. However, due to the limited sound collection effect of the existing microphone used for the collector, the analysis module will be affected by interference signals during the analysis process, resulting in low analysis accuracy...
