[0025] The following will be combined with the drawings of the specific embodiments of the utility model to clearly and completely describe the exemplary scheme of the utility model. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be the common meanings understood by people with ordinary skills in the relevant field.
[0026] like Figure 1 and Figure 3 As shown, for the basic entry needs of braille learners, the intelligent braille learning machine of this embodiment mainly realizes the braille touch reading function, braille dictation test function and search function. The intelligent braille learning machine includes a shell 1, and the entire shell is arc-shaped, with smooth lines and beautiful appearance. A vibration motor 2 is arranged on the upper front of the shell 1. The number of vibration motors 2 is 12, and a group of six constitutes two braille characters. The vibration motor 2 mainly acts as a touchable braille point to give feedback to the learner through vibration. A braille button 3 is arranged on the lower front of the shell 1. The braille button 3 can adopt a six-foot self-locking switch. Pressing and lifting correspond to the 1 and 0 point sequence respectively. The number of braille buttons 3 is also 12, and a group of six constitutes two braille characters. The self-locking switch is used as the input braille point in the test function and the search function to realize the user's input operation; in the test function, the learner presses the corresponding point according to the broadcasted title text; in the search function, the learner presses the braille that he wants to query, and the learning opportunity broadcasts the pronunciation of the corresponding text. A TF card slot 4 is provided in the middle of the front side of the housing 1 for inserting a TF card. The main control module inserts a card through the TF card slot to regularly update the learning content.
[0027] like Figure 2As shown, the side of the housing 1 is provided with function buttons, including up and down selection buttons 5, confirmation buttons 6 and power button 7. The up and down selection buttons 5 are used by learners to select the touch reading function, test function or search function; the confirmation button 6 is used to confirm the selected function; the power button 7 serves as the power switch of the entire device. The side of the housing 1 is also provided with an earphone jack 8 for connecting wired earphones. The side of the housing 1 is provided with a plurality of heat dissipation ports 9 in parallel, which are used for air circulation inside and outside the housing 1, and are conducive to heat dissipation of the components inside the housing 1 when they are working.
[0028] A touch screen 10 is provided on the front of the housing 1 above the vibration motor 2. The touch screen 10 has the same function as the function keys, and is used by learners to perform function selection operations.
[0029] Preferably, the housing portion where the vibration motor 2, the touch screen 10 and the Braille buttons 3 are located is tilted to facilitate viewing and operation by users.
[0030] A mainboard is installed inside the housing 1, and the mainboard includes a main control module, a voice playback module and a power module. The main control module is respectively connected to the vibration motor 2, the Braille button 3, the function button, the TF card slot 4, the voice playback module, the touch screen 10 and the power module.
[0031] The main control module is used to control the voice broadcast, control the vibration motor 2 and identify the input of the self-locking switch. Preferably, the main control module uses a CH32V307 single-chip microcomputer, which is a 32-bit RISC core MCU based on the RISC-V instruction set and architecture design, and the working power supply is 3.3V.
[0032] like Figure 4 As shown, the voice playback module uses the ES8388 chip, and the working voltage is 2V ~ 3.6V; it is connected to the headphone jack 8, so as to realize human-computer voice interaction. In the touch reading function, the voice playback module broadcasts the text content to the learner; in the test function, the voice playback module broadcasts the question text; in the search function, the main control module recognizes the Braille dot sequence input by the learner, and controls the voice playback module to broadcast the pronunciation of the Braille.
[0033] Preferably, the power module adopts MP2225 power regulator, with an input voltage of 4.5-18V and an adjustable output voltage as low as 0.6V, to supply power to various electrical components of the learning machine and meet the power demand of the whole machine.
[0034] Here’s how it works:
[0035] After the user turns on the device, he or she selects a function using the up and down selection keys 5 and the confirmation key 6 or the touch screen 10 to enter each mode.
[0036] In the touch reading function, the voice playback module reads the text content. At the same time, the main control module controls the vibration motor 2 at the corresponding point to generate vibration feedback according to the text content, simulating the touch of the Braille point.
[0037] In the test function, the voice playback module reads the question text, and the learner needs to press the self-locking switch within 10 seconds according to the question. The main control module compares and determines whether it is correct or not. If it is wrong, the vibration motor 2 at the correct point will vibrate to help learners achieve efficient practice.
[0038] In the search function, the learner inputs the Braille that he wants to find through the self-locking switch, and the main control module controls the voice playback module to broadcast the pronunciation of the Braille, so that the learner can quickly master the pronunciation of the text.
[0039] The preferred embodiments for implementing the present invention have been described in detail above, but it should be understood that the role of these embodiments is only to exemplify, and is not intended to limit the scope, applicability or configuration of the present invention in any way. The protection scope of the present invention is defined by the attached claims and their equivalents. A person of ordinary skill in the art can make many changes to the above embodiments under the guidance of the present invention, and these changes all fall within the protection scope of the present invention.
