Acousto-optic embedding plate and control method thereof

Abstract

The invention provides an acousto-optic embedding plate. The acousto-optic embedding plate is characterized by comprising a cover plate (1), an embedding block (2), a magnet (3), an LED display screen (4), a base (5) and a magnetic switch (6). A power switch (9), a loudspeaker (10) and a mode switching button (11) are arranged in the base (5). The LED display screen (4) is installed in the base (5) in a buckling or binding mode. The cover plate (1) is installed on the base (5) in a buckling mode. A handle (7) is installed on the embedding block (2) through threads. The magnet (3) is installed between the handle (7) and the embedding block (2). The magnetic switch (6) is installed on the lower portion of the LED display screen (4) in a bonding mode. According to the acousto-optic embedding plate, by means of rich sound, light and image visual stimulation, an effective path is provided for hand operation of children with low vision, and the possibility is provided for the children with the low vision to complete hand-eye coordination training; meanwhile, in combination with corresponding cognition and speech training, vision recovery can be promoted effectively.

Description

technical field [0001] The invention belongs to the field of function-promoting toys, and relates to a visual development toy for low-vision children, in particular to an acousto-optic mosaic board and a control method thereof. Background technique [0002] Visual impairment has become a serious public health problem in my country and even in the world. The phenomenon of blindness caused by eye diseases is gradually spreading to young children, which should arouse the great attention of parents and society. The World Health Organization regards childhood blindness and low vision as one of the five priorities of "Vision 2020 - Enjoying the Right to See" to eliminate avoidable blindness globally. However, there are few low-vision toys in the domestic market, especially those targeted at developing low-vision children's vision, which cannot meet the needs of low-vision children's growth and seriously hinder the development of low-vision children's vision. For children with lo...

Problems solved by technology

However, there are few low-vision toys in the domestic market, especially for the development of low-vision children's vision, which cannot meet the needs of low-vision children's growth and seriously hinders the development of low-vision children's vision.

For children with low vision, the existing fine beads, enlarged word cards, and audio books have a single stimulation mode and are not very interesting. The development of function and the development of functional vision rehabilitation training
