Abstract

The invention discloses a teaching platform. The teaching platform structurally comprises a platform frame, a display screen and a platform column. The display screen is mounted on the platform frame;and the platform frame is locked with the platform column. The platform frame is composed of a supporting arc frame, a baffle, a sidetone wing, a keyboard drawer and a rack. The supporting arc frameis locked with the baffle and the rack; the rack is provided with the sidetone wing; and the keyboard drawer is connected with a rack track; the baffle is spliced and connected with the rack. The sidetone wing comprises a telescopic pressing plate, a left concave plate, a left turning plate, a right turning plate and a right concave plate. The telescopic pressing plate is connected with the left concave plate and the right turning plate through the track; and the left concave plate is connected with the left turning plate. According to the invention, the telescopic pressing plate drives the left concave plate and the right turning plate to be folded in a concave mode, the sidetone wing collects audio in the middle to produce sounds, an audio trimmer processes the audio, high-definition audio and noisy audio are separated; four surrounding loudspeakers cooperate with each other in a circulating sound production mode, three-dimensional circulating sound production is achieved, the propagation distance is long, and the propagation sound quality is clear.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to a teaching platform. Background technique [0002] The multimedia teaching podium is a product that integrates the podium with computers, multimedia control systems, video booths, audio equipment, audio and video converters and other electronic products, which is convenient for lecturers to give lectures to learners. [0003] In the prior art, the traditional lectures are directly uttered, the transmission distance is short, and the sound quality is not clear. The sound is transmitted through the earphones. Not only is the earphone uncomfortable to wear, but the sound transmitted is relatively noisy, easy to lose voice, and affects the quality of teaching. Contents of the invention [0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a teaching podium to solve the problem of direct sounding in traditional lectures, sho...
