Abstract

The invention belongs to the technical field of electronic teaching, and discloses an interconnected blackboard with a playback function and a system thereof. The interconnected blackboard comprises an installation outer shell, a touch screen and a movable adjustment device; the touch screen and the movable adjustment device are arranged at one side of the installation outer shell, the touch screen is embedded in the installation outer shell, and the touch screen comprises a display area and a writing and recording area; sliding grooves are formed in the positions, located on the two sides ofthe touch screen, of the outer wall of one side of the outer shell, the movable adjusting device comprises a movable push rod, and the two ends of the movable push rod are located in the two sliding grooves respectively and slide along the sliding grooves; the display area and the writing and recording area are located on the two sides of the push rod respectively, and when the push rod moves, thearea of the display area and the area of the writing and recording area change accordingly. In conclusion, the adjustable display area and the writing and recording area are arranged on the interconnected blackboard, so that playback use and writing use of the interconnected blackboard can be realized at the same time, and the size of the corresponding area can be adjusted according to actual userequirements.

Description

technical field [0001] The invention belongs to the technical field of electronic teaching, and in particular relates to an interconnected blackboard with a playback function and a system thereof. Background technique [0002] With the development of modern society, electronic teaching is gradually replacing traditional teaching; currently, most commonly used electronic teaching is the cooperation of terminal computer and projection device, but this electronic teaching method can only carry out teaching with fixed courseware, and the interactive teaching effect is poor. [0003] Based on the above problems, a blackboard that can record teaching blackboard writing is proposed in the prior art. On the blackboard, written interactive teaching can be performed, and specified courseware or blackboard writing can be displayed and played, so as to improve the teaching effect of electronic teaching. ; [0004] However, in the prior art, the above-mentioned blackboard cannot realize...
