Their core needs focus on balancing "stable use anytime, anywhere" and "compact storage".

[0003] However, existing portable English listening training devices generally lack a dedicated support structure design. When users are in scenarios without desktop support (such as during commutes or when studying outdoors while standing), they need to hold the device with one hand continuously. Prolonged use can easily lead to hand fatigue and affect concentration. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a portable English listening training device, which solves the problem that existing portable English listening training devices require one-handed holding in scenarios without desktop support, easily leading to hand fatigue.

[0005] To achieve the above objectives, this utility model provides a portable English listening training device, including a main body. A long, narrow storage groove is provided in the middle of the back of the main body. A support assembly is movably disposed inside the storage groove. The support assembly includes a metal hinge, a retractable support arm, and an arc-shaped silicone suction cup. One end of the metal hinge is fixed to the inner wall of one end of the storage groove by bolts, and the other end is fixedly connected to the retractable support arm. The arc-shaped silicone suction cup is installed at the end of the retractable support arm away from the metal hinge. An angle adjustment mechanism is provided between the retractable support arm and the main body.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Preferably, the telescopic support arm consists of a fixed section and a movable section, with one end of the fixed section having a through hole and one end of the movable section extending through the through hole into the interior of the fixed section.

[0008] Preferably, a key bar is fixedly provided on the outer surface of the movable section along the axial direction, and a first keyway is provided on the inner wall of the through hole for the key bar to pass through.

[0009] Preferably, the key bar has several slots evenly spaced along its length, and the fixed section is coaxially rotatably connected to a retaining ring at one end near the through hole. The retaining ring has a through hole, and the movable section slides through the through hole. The inner wall of the through hole has a second keyway for the key bar to pass through.

[0010] Preferably, the angle adjustment mechanism includes a positioning plate rotatably mounted inside the storage groove. A positioning protrusion is fixedly connected to the positioning plate. Multiple positioning holes that are adapted to the positioning protrusion are equally spaced along the axial direction on the side of the fixed section near the positioning plate. After the positioning protrusion engages with any positioning hole, a triangular support structure is formed between the positioning plate, the telescopic support arm, and the main body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The device is stably fixed on a smooth surface by a support component, freeing the user's hands, avoiding hand fatigue caused by prolonged holding, and improving learning concentration; The support components can be completely stored in the groove on the back of the main unit without increasing the size of the device, ensuring portability; at the same time, the telescopic support arm and angle adjustment mechanism support flexible adjustment of length and angle to adapt to diverse usage scenarios.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 As shown, this embodiment provides a portable English listening training device, including a main unit 1. The main unit 1 serves as the core carrier for the listening training function, integrating basic components such as audio playback and display interaction. To provide support, a long, narrow storage groove 101 is provided in the middle of the back of the main unit 1. This groove provides storage space when the support components are not in use, ensuring the overall compactness and portability of the device.

[0016] The storage recess 101 has a movable support assembly inside, which includes a metal hinge 2, a retractable support arm 3, and an arc-shaped silicone suction cup 4. One end of the metal hinge 2 is bolted to the inner wall of one end of the storage recess 101, and the other end is fixedly connected to the retractable support arm 3. The metal hinge 2 provides a pivot point for the retractable support arm 3, allowing it to flexibly rotate out of or retract from the storage recess 101. The retractable support arm 3 can be adjusted in length according to the usage scenario, improving support adaptability. The arc-shaped silicone suction cup 4 is installed at the end of the retractable support arm 3 away from the metal hinge 2. Utilizing the sealing and adsorption properties of the silicone material, it can stably fix the device to a smooth surface (such as a car window, wall, or tabletop), replacing hand grip.

[0017] In summary, the improvement of this embodiment lies in the fact that the support component enables the device to be stably fixed on a smooth surface, freeing the user's hands, avoiding hand fatigue caused by prolonged holding, and improving learning concentration.

[0018] Based on the above, other structures also need to be disclosed in detail, such as: To achieve the telescopic function of the support arm, the telescopic support arm 3 consists of a fixed section 301 and a movable section 305. One end of the fixed section 301 has a through hole 302, and one end of the movable section 305 extends through the through hole 302 into the interior of the fixed section 301. Length adjustment is achieved by sliding the movable section 305 within the fixed section 301. To prevent relative rotation between the movable section 305 and the fixed section 301, a key bar 306 is axially fixed to the outer surface of the movable section 305. The inner wall of the through hole 302 has a first keyway 303 for the key bar 306 to pass through. The key bar 306 and the first keyway 303 cooperate to form a guiding structure, ensuring stability during the telescopic process.

[0019] The key bar 306 has several equally spaced slots 307 along its length. A retaining ring 308 is coaxially rotatably connected to one end of the fixed section 301 near the through hole 302. The retaining ring 308 has a through hole 309, through which the movable section 305 slides. A second keyway 310 for the key bar 306 to pass through is formed on the inner wall of the through hole 309. Rotating the retaining ring 308 allows its inner wall to engage or disengage from the slots 307, locking or unlocking the length of the movable section 305 and the fixed section 301, facilitating quick and easy fixing of the support arm length.

[0020] To achieve angle adjustment of the main unit 1, an angle adjustment mechanism 5 is provided between the telescopic support arm 3 and the main unit 1. This mechanism includes a positioning plate 501 rotatably mounted inside the storage groove 101. A positioning protrusion 502 is fixedly connected to the positioning plate 501. Multiple positioning holes 304, which are adapted to the positioning protrusion 502, are equally spaced along the axial direction on the side of the fixed section 301 near the positioning plate 501. When the positioning protrusion 502 engages with any of the positioning holes 304, a triangular support structure is formed between the positioning plate 501, the telescopic support arm 3, and the main unit. The stability of the triangle ensures that the main unit 1 is stably placed at a set angle, allowing the user to select a suitable angle according to their line of sight, thus improving user comfort.

[0021] In summary, the workflow of this solution is as follows: When the support function is needed, manually rotate the retractable support arm 3 out of the storage groove 101 on the back of the main unit, and rotate the support arm through the metal hinge 2 until it is in an unfolded state with the main unit body 1.

[0022] In the initial state, the second keyway 310 of the retaining ring 308 coincides with the first keyway 303 of the fixed section 301, and the key bar 306 can slide freely along the two keyways. According to the space requirements of the usage scenario, the movable section 305 can be stretched or shortened. After adjusting to a suitable length, the retaining ring 308 is rotated to make the second keyway 310 and the first keyway 303 misaligned. At this time, the inner wall of the through hole 309 of the retaining ring 308 is engaged with the corresponding slot 307 on the key bar 306, and the key bar 306 is restricted from moving. The lengths of the movable section 305 and the fixed section 301 are fixed.

[0023] Rotate the positioning plate 501 in the storage groove 101 to make it contact the telescopic support arm 3. According to the user's line of sight height, insert the positioning protrusion 502 on the positioning plate 501 into the corresponding positioning hole 304 on the fixing section 301. At this time, the positioning plate 501, the telescopic support arm 3 and the main body 1 form a stable triangular support structure, and the angle of the main body 1 is fixed.

[0024] Press the curved silicone suction cup 4 onto the smooth surface to expel the air from the suction cup and use atmospheric pressure to achieve stable adsorption of the device.

[0025] After use, first peel the silicone suction cup off the surface; then move the positioning plate 501 to separate the positioning protrusion 502 from the positioning hole 304; rotate the retaining ring 308 in the opposite direction to make the second keyway 310 coincide with the first keyway 303 (unlock the support arm), and retract the movable section 305 into the fixed section 301 (shortest length); finally, put the support assembly completely into the storage groove 101 to complete the storage.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
