Abstract

The invention discloses a braille reading device, and belongs to the technical field of special reading equipment. The braille reading device comprises a housing which wraps an air cavity; at least one air hole is formed in the surface of one side of the housing; a valve layer for controlling air flowing out is arranged between the air hole and the air cavity. The braille reading device can effectively solve the problem that the existing braille cannot be recycled and the resource is seriously wasted.

Description

technical field [0001] The invention relates to the technical field of special reading equipment, in particular to a braille reading device. Background technique [0002] The reading method of the visually impaired mainly uses Braille. A standard Braille character is composed of a dot matrix of 2*3 dots, and different meanings are expressed by the presence or absence of protrusions at different dots. Displaying Braille characters requires controlling the raised points of different dots. [0003] Traditional braille displays are usually achieved by making raised dot symbols on paper. Because braille display is realized by destroying paper, it is difficult to repeatedly use the same piece of paper to make eminence point symbols in existing braille display, thus causing serious waste of resources. Contents of the invention [0004] In order to solve the problem that existing braille displays cannot be reused and serious waste of resources exists, an embodiment of the presen...
