Description

Technical Field

[0001] This invention relates to the field of English reading instruction technology, and in particular to an English reading instruction device for English teaching. Background Technology

[0002] Currently, in the field of English teaching, English repetition is an important way to improve oral skills, but there are many deficiencies in related equipment.

[0003] Traditional pronunciation aids are mostly simple audio playback devices that can only provide standard pronunciations and cannot simulate the position and movement of the tongue when pronouncing different phonemes. Learners cannot intuitively feel the changes inside the oral cavity and cannot master pronunciation skills. Although most existing technologies focus on functions such as speech recognition, they are seriously lacking in the simulation of the movement of the speech organs, especially the tongue and the coordination of the teeth. This greatly affects learners' mastery of the correct pronunciation method, causing them to only imitate the sound and not fundamentally understand the principles of pronunciation, thus affecting the learning effect and efficiency.

[0004] Therefore, there is an urgent need for an English reading aloud device that can accurately simulate the movement of the tongue to fill the market gap and improve the quality of English teaching. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide an English reading aloud device for English teaching. By setting up a tongue-simulating mechanism in conjunction with a drive roller to control the contraction and release of a steel wire, the movement of the tongue tip is controlled. At the same time, a rotating seat driven by a motor adjusts the angle of the tongue root, and the movement of the lower and upper triangular bodies linked by a servo motor realizes the arching or deformation of the tongue body. It can accurately simulate the movement trajectory of the human tongue, such as raising, contracting, and arching, when pronouncing different phonetic symbols, thus solving the problem that existing English reading aloud devices cannot accurately simulate the tongue movement.

[0044] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0045] The English reading aloud device for English teaching provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0046] like Figures 1 to 23As shown, an embodiment of the present invention provides an English reading aloud device for English teaching, including a reading aloud simulation component 100 and a base 200. A sound-emitting device 210 is fixedly installed at the end of the base 200. The sound-emitting device 210 can emit international phonetic symbols or English words to facilitate learning. The sound-emitting device 210 can be used in conjunction with the reading aloud simulation component 100. The reading aloud simulation component 100 can simulate tongue phonetic symbols based on the sound emitted by the sound-emitting device 210 to facilitate correction of the pronunciation of the learner. The reading aloud simulation component 100 is composed of a lower bite part 110, a tongue imitation mechanism 120, a drive roller 180, and an upper bite part 190. The tongue imitation mechanism 120 cooperates with the lower bite part 110 and the upper bite part 190 to realize teaching. The drive roller 180 can drive the tongue imitation mechanism 120.

[0047] The tongue-simulating mechanism 120 consists of a tongue tip 130, a tongue body 140, and a tongue root 170. The tongue-simulating mechanism 120 can simulate the movement of the human tongue during vocalization. By controlling the movement of the tongue tip 130, tongue body 140, and tongue root 170 through the tongue-simulating mechanism 120, the position of the tongue during pronunciation can be simulated, for example:

[0048] When pronouncing the phonetic symbol / iː / , the tip of the tongue touches the lower teeth and the front of the tongue is raised as high as possible.

[0049] When pronouncing the phonetic symbol / ɪ / , the tip of the tongue touches the lower teeth, and the front part of the tongue rises to the palate;

[0050] ...When pronouncing the phonetic symbol / ʃ / , the entire tongue is raised, with the front of the tongue approaching the upper gum ridge...;

[0051] The lifting and lowering of the tongue tip 130 and the tongue body 140 can be controlled by the drive roller 180, and the lifting and lowering of the tongue root 170 can be controlled by the motor 173. At the same time, the arching of the tongue body 140 can be controlled by the servo motor 174. Thus, when the sound-producing device 210 produces English, the tongue-simulating mechanism 120 can simulate the movement state of the tongue when producing sound.

[0052] The lower occlusal portion 110 is rotatably connected to the top of the base 200. The lower gingival portion 111 is fixedly installed on the inner wall of the front end of the lower occlusal portion 110, and the lower tooth portion 112 is fixedly installed on the top of the lower gingival portion 111. The upper occlusal portion 190 is fixedly installed on the inner wall of the front end of the upper occlusal portion 191, and the upper tooth portion 192 is fixedly installed at the bottom of the upper gingival portion 191. A rubber mimic tongue 114 is provided inside the lower occlusal portion 110. The rubber mimic tongue 114 is sleeved on the outer end of the mimic tongue mechanism 120, and the inner wall of the rubber mimic tongue 114 is in contact with the mimic tongue mechanism 120. The lower occlusal portion 110, the lower gingival portion 111, the upper occlusal portion 190, and the upper gingival portion 191 are all made of transparent acrylic plates. The rubber mimic tongue 114 is made of red rubber. The upper tooth portion 192 and the lower tooth portion 112 are both made of colored transparent material. The color setting makes it easier for scholars to observe and learn.

[0053] In this embodiment, as Figures 17 to 23 As shown, the tongue body 140 includes a base 141. The front wall of the base 141 is rotatably connected to the end wall of the tongue tip 130. A square groove 142 is provided on the bottom surface of the middle part of the base 141. Slide rails 144 are fixedly installed on the inner walls of both ends of the square groove 142. The same lower triangular body 145 is slidably connected to the two sets of slide rails 144. A rail fastening plate 146 is fixedly installed at the four corners of the bottom of the lower triangular body 145, and the rail fastening plate 146 is engaged with the corresponding slide rail 144. The rail fastening plate 146 can ensure that the lower triangular body 145 can move linearly on the slide rail 144 without derailment. An upper triangular body 150 is provided on the top of the lower triangular body 145. The upper triangular body 150 is slidably engaged with the inclined wall of the lower triangular body 145. The inner walls on both sides of the base 141 are fixed. A slide rail 143 is installed, and the upper triangular body 150 is slidably connected to the base 141 through the slide rail 143. The slide rail 143 limits the movement of the upper triangular body 150. Both sides of the inclined wall of the upper triangular body 150 and the lower triangular body 145 are fixedly installed with mating plates 151. The inner walls of the mating plates 151 on both sides of the upper triangular body 150 are provided with inner sliding grooves 152. Multiple sets of ball bearings 153 are rotatably installed on the outer walls of the mating plates 151 on both sides of the lower triangular body 145. The multiple sets of ball bearings 153 on the same side cooperate with the corresponding inner sliding grooves 152. The cooperation between the ball bearings 153 and the inner sliding grooves 152 facilitates the relative movement between the upper triangular body 150 and the lower triangular body 145. An arched top block 160 is fixedly installed on the top of the upper triangular body 150.

[0054] In this embodiment, as Figures 14 to 16As shown, the tongue base 170 includes a rotating seat 172. A flexible plate 176 is fixedly installed on the front wall of the rotating seat 172. The front wall of the flexible plate 176 is rotatably connected to the end wall of the base 141. The flexible plate 176 is made of elastic rigid plastic. When lateral pressure is applied, the flexible plate 176 can deform slightly. An inclined support plate 113 is fixedly installed on the bottom inner wall of the lower biting part 110. The inclined support plate 113 can be made of transparent acrylic sheet, which can facilitate observation by the observer. Both sides of the top end of the inclined support plate 113 are fixedly installed with... The rotating base 172 has two sets of limit frames 171 on each side of its end, which are rotatably connected to the top of the limit frames 171. The limit frames 171 support the rotating base 172. A motor 173 is fixedly installed on the outer wall of the connection between the left limit frame 171 and the rotating base 172, and the output end of the motor 173 is fixedly connected to the rotating base 172. By driving the motor 173, the rotating base 172 can be rotated, thereby realizing the rotation of the tongue root 170. A servo motor 174 is fixedly installed on the inner wall of the bottom of the rotating base 172, and the servo motor 174 outputs... A rotating plate 175 is fixedly installed at the outlet. A rotating frame 147 is rotatably connected to the center of the bottom of the lower triangular body 145. A connecting plate 148 is slidably connected to the inner walls on both sides of the rotating frame 147. The other end of the connecting plate 148 is slidably connected to the inner walls on both sides of the rotating plate 175. In this invention, when it is necessary to control the tongue to lift, the servo motor 174 is driven to make the rotating plate 175 swing, so that the rotating plate 175 drives the connecting plate 148 to swing. Under the buffering effect of the rotating frame 147, the connecting plate 148 can drive the lower triangular body 145 to move inward. Under the limiting action of the slide 143, the lower triangular body 145 can push the upper triangular body 150 upward, causing the upper triangular body 150 to push the arched top block 160, which in turn forces the arched top block 160 to push the rubber mimic tongue 114, thus controlling the arching of the tongue. When the lower triangular body 145 moves to its limit position, the servo motor 174 continues to swing, which allows the lower triangular body 145 to apply pressure to the base 141, thereby causing the base 141 to deform the flexible plate 176, thus realizing the movement of the tongue.

[0055] As one implementation method in this embodiment, such as Figures 9 to 13As shown, the drive roller 180 is rotatably connected to the top end of the inclined support plate 113. A left spiral groove 181 is formed on the top outer wall of the drive roller 180, and a right spiral groove 182 is formed on the bottom outer wall of the drive roller 180. The right spiral groove 182 and the left spiral groove 181 are symmetrically arranged. When the drive roller 180 rotates, the right spiral groove 182 and the left spiral groove 181 rotate in opposite directions, thus the movement of the steel wire rope 183 within the spiral grooves is also opposite. Steel wire rope 183 is wound in both the right spiral groove 182 and the left spiral groove 181. The steel wire rope 183 in the left spiral groove 181 movably passes through the arched top block 160 and is fixedly connected to the right side of the top of the tongue tip 130. The steel wire rope 183 in the right spiral groove 182 movably passes through... The base 141 is fixedly connected to the bottom left side of the tongue tip 130. The bottom of the inclined support plate 113 is fixedly mounted with a second motor 184, and the output end of the second motor 184 is fixedly connected to the end wall of the drive roller 180. In this invention, the second motor 184 drives the drive roller 180 to rotate, thereby releasing or retracting the steel wire rope 183 on the drive roller 180, thereby causing the tongue tip 130 to lift or retract. When the tongue tip 130 is lifted or retracted to a certain position, the tongue body 140 is lifted or retracted, which conforms to the movement law of the tongue and realizes the control of the movement of the tongue tip and the tongue body. Similarly, the first motor 173 drives the rotating seat 172 to rotate, which can realize the control of the lifting or retraction of the tongue root.

[0056] As one implementation method in this embodiment, such as Figures 1 to 4 As shown, a second cylinder 193 is fixedly installed at the top end of the base 200, and the output end of the second cylinder 193 is fixedly connected to the bottom of the upper biting part 190. By controlling the second cylinder 193, the position of the upper biting part 190 can be changed. A first cylinder 115 is rotatably connected to the top front end of the base 200, and the output end of the first cylinder 115 is rotatably connected to the bottom front end of the inclined support plate 113. Similarly, by controlling the first cylinder 115, the lower biting part 110 can be rotated, thereby simulating the movement of the human jaw. In this invention, when controlling the simulated tongue... While the mechanism 120 is moving, it works in conjunction with the drive cylinders 115 and 193 to move the lower biting part 110 and the upper biting part 190, thereby changing the relative position of the lower teeth 112 and the upper teeth 192. Combined with the position of the rubber mimic tongue 114, it can simulate various phonetic symbols. For example, by driving the upper biting part 190 downward through the drive cylinder 193, while driving the lower biting part 110 upward through the drive cylinder 115, the lower teeth 112 can come into contact with the upper teeth 192.

[0057] The working principle of the technical solution provided by this invention is as follows: In English reading instruction, the sound-producing device 210 emits the English word to be learned (phonetic pronunciation), which drives the drive roller 180 to rotate via the drive motor 184, thereby releasing or retracting the steel wire rope 183 on the drive roller 180 (when the steel wire rope 183 in the left spiral groove 181 is retracted, the steel wire rope 183 in the symmetrically arranged right spiral groove 182 is released), thereby causing the tongue tip 130 to rise or retract. When the tongue tip 130 rises or retracts to a certain position, the tongue body 140 is raised or retracted (refer to the appendix of the instruction manual). Figure 11 This conforms to the movement pattern of the tongue, enabling control of the movement of the tongue tip and body. Similarly, by driving motor 173 to drive the rotating seat 172 to rotate, control the lifting or retraction of the tongue root.

[0058] When it is necessary to control the tongue to lift, the servo motor 174 is driven to make the rotating plate 175 swing, which in turn makes the connecting plate 148 swing. Under the buffering effect of the rotating frame 147, the connecting plate 148 can drive the lower triangular body 145 to move inward. Under the limiting effect of the slide rail 143, the lower triangular body 145 can push the upper triangular body 150 upward, which in turn pushes the arched top block 160, forcing the arched top block 160 to push the rubber mimic tongue 114, thus controlling the arching of the tongue. When the lower triangular body 145 moves to the limit position (i.e., in contact with the inner walls on both sides of the base 141), the servo motor 174 continues to swing, which can make the lower triangular body 145 apply pressure to the base 141, thereby causing the base 141 to drive the flexible plate 176 to deform, thus realizing the movement of the tongue.

[0059] While controlling the movement of the tongue-mimicking mechanism 120, in conjunction with the drive cylinder 115 and cylinder 2193, the lower biting part 110 and the upper biting part 190 can move, thereby changing the relative position of the lower teeth 112 and the upper teeth 192. In conjunction with the position of the rubber mimicking tongue 114, various different phonetic symbols can be simulated.
