[0054] Such as image 3 As shown, the device of the present invention is mainly divided into two parts: the first part is the main controller with keyboard, microphone and LCD display screen, and the second part is a group (6) of wireless devices attached to different parts of the body of the hearing impaired. Vibrating patch. The main controller is used to encode the voice input signal or keyboard input signal in Braille, and send the encoded 6-bit binary code information sequence to the target vibration patch through the ZigBee wireless network. The vibrating patch receives the information sequence sent by the main controller, and converts it into a control signal for the vibrator, so that the vibrator vibrates according to the information sequence. The hearing impaired understand the meaning of the message by sensing the vibrations of the individual patches.
[0055] Such as Figure 4 As shown, the main controller includes: a processor, a voice signal processing module, ...
