Campus interactive spoken English pronunciation teaching device

Abstract

The invention discloses a campus interactive spoken English pronunciation teaching device which structurally comprises a shell, a cooling hole and a loudspeaker. Buffering devices are arranged among the top ends of a first bottom frame and second bottom frame and the bottom end of the shell, a closed cover is rotated with a hand to open a ventilation hard pipe, an air pipe passing an external airsupply device is connected into a ventilation soft pipe of the lower portion of the ventilation hard pipe, a rotatable circular strip and a fixed circular strip can simultaneously clamp the outer surface of the ventilation soft pipe outside the external air pipe under the action of a rotating part, a fixed bump is fixedly connected and pre-clamped by a fixed part, a threaded rod is rotated, so that a spacer contact with the ventilation soft pipe, fixing is improved, an air bag connected at the bottom end of the ventilation soft pipe is inflated by the external air supply device, the inflated air bag provides elastic acting force for lower portion of the outer surface of the shell, and vibratory buffering power can be provided for the outside of the shell of the device, so that loosening orbreakage of inner and outer components of the shell is prevented.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a campus interactive oral English pronunciation teaching device.

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, a campus interactive oral English phonetic teaching device is proposed, which solves the problem that the internal and external parts of the device may be loosened or damaged due to the vibration generated by passing through a relatively bumpy road section when moving, so that the device can be used The outside of the shell provides vibration buffering force to prevent loosening or damage of the internal and external parts of the shell
