Technical Field

The utility model relates to the technical field of teaching equipment, in particular to a multimedia teaching device.

Background

The blackboard is one of the most common teaching aids in traditional teaching mode for the demonstration of writing, along with scientific and technological development, the teaching aid is constantly upgraded. In the facility configuration of a modern classroom, the use of an electronic blackboard is very common, and when audio and video playing is performed in the electronic blackboard, a corresponding sound device is required to perform audio playing.

Among the common multimedia teaching device in the market at present, the position of stereo set is most concentrated in bottom, top or both sides of equipment, and towards the place ahead and adopt ordinary stereo set design, ordinary stereo set not only occupation space is great, influences the pleasing to the eye degree of product, and the direction of making a sound also has the sound directive property of limitation moreover.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide the multimedia teaching device, which enables any position in a use space to have good sound effect, can also improve the squeaking phenomenon generated when a microphone is connected for use, and also improves the scientific and technological feeling of products.

In order to achieve the purpose, the utility model adopts the technical scheme that: a multimedia teaching apparatus comprising: install display writing unit and clipboard on the frame respectively, it sets up in the display at panel rear to show writing unit including the panel, install at least one resonance loudspeaker on the rear surface of clipboard, resonance loudspeaker is connected with the rear surface laminating of clipboard.

The technical scheme of further improvement in the technical scheme is as follows:

1. in the scheme, the writing board is a glass blackboard or an iron board.

2. In the scheme, the writing board comprises a wood board layer and an iron sheet layer attached to the front side surface of the wood board layer.

3. In the above scheme, the writing board comprises two iron sheet layers arranged in parallel and a foaming layer arranged between the two iron sheet layers.

4. In the above scheme, the panel is a glass panel.

5. In the above scheme, a rough surface layer is formed on the front surface of the panel through coating or etching.

6. In the above scheme, the resonance horn is connected with the writing board in an adhesive manner.

Comprises two writing boards which are respectively positioned at the left side and the right side of a display writing unit.

The back surface of the writing board is provided with 2 resonance horns at intervals.

Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages and effects:

the multimedia teaching device reduces the volume of sound on the device, releases the space occupied by a common loudspeaker, improves the utilization rate of the internal space of a product, enables the sound not to be restricted by the propagation direction any more, realizes 360-degree unimpeded propagation, enables any position in the use space to have good sound effect, can improve the squeaking phenomenon generated when the microphone is connected for use, and also improves the technological sense of the product on the basis of simultaneously meeting the requirements of traditional teaching and modern multimedia teaching.
