[0002] In the process of English teaching, in order to train students' listening skills, English materials are played through listening training instruments. By listening to the English materials and refining them, students can answer questions on the test paper to achieve the purpose of listening training. The existing listening training instruments still have certain defects when used, such as;

[0003] The sound of traditional listening training devices when playing English materials is relatively empty. When used in larger classrooms, the sound emitted by the built-in speakers of the listening training devices is too scattered, causing the sound to be easily distorted. Utility Model Content

[0004] The utility model discloses a hearing training instrument, which aims to solve the technical problem that the sound of the traditional hearing training instrument is relatively empty when playing English materials, and when used in a larger classroom, the sound transmitted by the hearing training instrument through the built-in speaker is too scattered, resulting in easy distortion of the sound.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hearing training instrument comprises a player and four groups of legs fixedly arranged at the lower end of the player, two groups of speaker dust covers are embedded and connected at the front end of the player, a handle is installed at the upper end of the player, and also comprises: a sound gathering mechanism: the sound gathering mechanism comprises a rotating shaft rotatably connected to the front end of the speaker dust cover, a T-shaped threaded rod is fixedly arranged at the front end of the rotating shaft, a push plate is threadedly connected to the T-shaped threaded rod, a pushing member is fixedly arranged at the lower end of the push plate, a baffle plate is fixedly arranged at the lower end of the pushing member, a support frame is fixedly arranged at the front end of the player near the bottom of the speaker dust cover, and the rear end of the baffle plate is rotatably connected in the support frame; a dust cleaning mechanism: the dust cleaning mechanism is fixedly arranged on the outer circumferential surface of the rotating shaft, and the dust cleaning mechanism is used to clean the accumulated dust on the speaker dust cover.

[0007] In this solution, by setting up a T-threaded rod, when the T-threaded rod is manually rotated, the four groups of pushing members can push the four groups of baffles outward or inward, adjust the space formed by the four groups of baffles, and then adjust the sound concentration as needed, and when the T-threaded rod rotates, its cleaning mechanism can clean the dust accumulated on the dust cover of the speaker.

[0008] In a preferred embodiment, the pushing member includes a first connecting frame fixedly arranged at the lower end of the push plate, a support plate is rotatably connected in the first connecting frame, one end of the support plate is rotatably connected to a second connecting frame, and the second connecting frame is fixedly arranged at the upper end of the enclosure plate.

[0009] By setting up the first connecting frame, one end of the support plate will be driven to move while following the movement of the push plate. When one end of the support plate moves, the inclination angle will change because the other end is rotatably connected to the second connecting frame. When the inclination angle of the support plate changes, the enclosure plate will be pushed to rotate in the support frame.

[0010] In a preferred embodiment, the dust cleaning mechanism includes a pad fixedly arranged on the outer peripheral surface of the rotating shaft, a brush is fixedly arranged on one side of the pad close to the speaker dust cover, and a dust attracting part for collecting dust is fixedly arranged at the front end of the player close to the lower end of the brush, and the dust attracting part includes a dust attracting belt fixedly arranged at the front end of the player, one end of the dust attracting belt is fixedly arranged on the upper end of the baffle plate, an dust collecting groove is opened on the baffle plate near one end of the dust attracting belt, a collecting frame is installed at the lower end of the baffle plate close to the dust collecting groove, and a lower end plate is installed at the lower end of the collecting frame through a hinge.

[0011] The provided pad drives the brush to rotate along with the rotation of the rotating shaft, thereby sweeping off the dust on the dust cover of the speaker. Part of the swept away dust falls into the collection frame along the curved and smooth dust guiding belt under the action of gravity, making it easier to clean the dust.

[0012] The present invention provides a hearing training device through improvement, which has the following improvements and advantages compared with the prior art:

[0013] First: The utility model can drive the push plate to move in different directions by manually rotating the T-shaped threaded rod counterclockwise or clockwise. When the push plate moves, the pushing member will simultaneously push the four groups of baffle plates to rotate outward or gather inward at the same time, thereby being able to adjust the gathering of sound as needed without increasing the volume, reducing energy consumption and sound distortion.

[0014] Second, in the utility model, when the T-shaped threaded rod rotates, the backing plate is driven to rotate at the same time, and when the backing plate rotates, the brush is driven to pass over the outer surface of the speaker dust cover, thereby facilitating the cleaning of dust accumulated on the speaker dust cover.

[0022] The utility model discloses a hearing training instrument which mainly applies the traditional hearing training instrument. When playing English materials, the sound is relatively empty. When used in a larger classroom, the sound emitted by the hearing training instrument through the built-in speaker is too scattered, resulting in a scene where the sound is easily distorted.

[0023] Reference Figure 1 and Figure 2A hearing training instrument comprises a player 1 and four groups of supporting feet 2 fixedly arranged at the lower end of the player 1, two groups of speaker dust covers 3 are embedded and connected at the front end of the player 1, and a handle 4 is installed at the upper end of the player 1. It also includes: a sound gathering mechanism: the sound gathering mechanism comprises a rotating shaft 5 rotatably connected to the front end of the speaker dust cover 3, a T-shaped threaded rod 6 is fixedly arranged at the front end of the rotating shaft 5, a push plate 7 is threadedly connected to the T-shaped threaded rod 6, a pushing member is fixedly arranged at the lower end of the push plate 7, a baffle plate 11 is fixedly arranged at the lower end of the pushing member, a support frame 12 is fixedly arranged at the front end of the player 1 near the bottom of the speaker dust cover 3, and the rear end of the baffle plate 11 is rotatably connected in the support frame 12; a dust cleaning mechanism: the dust cleaning mechanism is fixedly arranged on the outer circumferential surface of the rotating shaft 5, and the dust cleaning mechanism is used to clean the dust accumulated on the speaker dust cover 3.

[0024] In this solution, four sets of legs 2 are provided to provide a stable support for the player 1, the speaker dust cover 3 is used to isolate dust and protect the speaker, the handle 4 provides a force fulcrum for easy carrying, and the position of the push plate 7 is changed by manually rotating the T-threaded rod 6, pushing the baffle plate 11 to rotate outward or inward, adjusting the sound concentration as needed, and the dust accumulated on the speaker dust cover 3 is cleaned through the cleaning mechanism.

[0025] Among them, four groups of pushing members, baffle plates 11 and support frames 12 are arranged in a circular array with the T-shaped threaded rod 6 as the center. The frame formed by the four groups of baffle plates 11 can gather the sound, and by controlling the inclination angle of the baffle plates 11, the gathering of the sound can be adjusted as needed.

[0026] Reference Figure 2 and Figure 4 In a preferred embodiment, the pushing member includes a first connecting frame 8 fixedly arranged at the lower end of the push plate 7, a support plate 9 is rotatably connected to the first connecting frame 8, one end of the support plate 9 is rotatably connected to a second connecting frame 10, and the second connecting frame 10 is fixedly arranged at the upper end of the enclosure plate 11.

[0027] When the push plate 7 moves along the T-threaded rod 6, it will push the first connecting frame 8. Since the two ends of the support plate 9 are respectively connected to the first connecting frame 8 and the second connecting frame 10 by rotation, when the first connecting frame 8 is pushed, the inclination angle of the support plate 9 will also change, and then it will push or pull the baffle plate 11 to rotate outward or inward, so as to adjust the sound gathering.

[0028] Reference Figure 2 and Figure 3 In a preferred embodiment, the cleaning mechanism includes a pad 13 fixedly arranged on the outer peripheral surface of the rotating shaft 5, a brush 14 is fixedly arranged on one side of the pad 13 close to the speaker dust cover 3, and a dust collecting member for collecting dust is fixedly arranged at the front end of the player 1 close to the lower end of the brush 14.

[0029] Furthermore, the distance between the pad 13 and the speaker dust cover 3 is equal to the thickness of the brush 14, so that the brush 14 can fit on the front end of the speaker dust cover 3. When the rotating shaft 5 drives the pad 13 to rotate, the brush 14 will pass over the front end of the speaker dust cover 3 and sweep away the accumulated dust thereon, thereby achieving the technical effect of facilitating the cleaning of the accumulated dust on the speaker dust cover 3.

[0030] Reference Figure 2 and Figure 3 In a preferred embodiment, the ash guiding member includes an ash guiding belt 15 fixedly arranged at the front end of the player 1, one end of the ash guiding belt 15 is fixedly arranged at the upper end of the enclosure plate 11, an ash collecting groove 16 is opened at the enclosure plate 11 near one end of the ash guiding belt 15, a collecting frame 17 is installed at the lower end of the enclosure plate 11 near the ash collecting groove 16, and a lower end plate 18 is installed at the lower end of the collecting frame 17 through a hinge.

[0031] It is worth noting that the edge of the dust guiding belt 15 is set to an inwardly curved arc structure, and the material of the dust guiding belt 15 is leather. The surface of the dust guiding belt 15 is smooth. When the accumulated dust on the speaker dust cover 3 is swept away, part of the dust will slide into the collecting frame 17 along the dust guiding belt 15 under the traction of gravity to collect the dust. In addition, the leather is relatively elastic. When the baffle plate 11 is pushed and rotated outward, the leather will stretch and will not hinder the rotation of the baffle plate 11.

[0032] Working principle: When in use, manually rotate the T-threaded rod 6 counterclockwise or clockwise. While the T-threaded rod 6 rotates, its push plate 7 moves forward or backward according to the direction of rotation of the T-threaded rod 6. While the push plate 7 moves, the four groups of pushers simultaneously push the four groups of baffle plates 11 to rotate outward or inward, thereby expanding outward or contracting inward the gathering space formed by the four groups of baffle plates 11, and then being able to adjust the gathering nature of the sound as needed without increasing the volume, reducing energy consumption while also reducing sound distortion.

[0033] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method steps, or a complete technical solution. Equivalent replacement or changes based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
