[0001] This utility model relates to the field of speaker technology, specifically a small speaker with an arc-shaped sound wave diffusion panel. Background Technology

[0002] A speaker is a device that converts audio signals into sound. In simple terms, it refers to a speaker cabinet or subwoofer cabinet with a built-in power amplifier that amplifies the audio signal before playing the sound back from the speaker itself, making the sound louder. The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the audio system, responsible for converting electrical signals into sound signals for people to hear directly.

[0003] Current speakers typically emit sound directly without diffusing it, resulting in poor sound quality, inconvenience, and reduced practicality. To address this, we propose a small speaker with an arc-shaped sound wave diffusion panel. Summary of the Invention

[0004] The purpose of this invention is to provide a small speaker with an arc-shaped sound wave diffusion panel to solve the problem mentioned in the background art that when a speaker is used, it usually directly emits sound and cannot diffuse the emitted sound, resulting in poor sound quality, inconvenience in use, and reduced practicality of the device.

The adjusting diffusion mechanism includes a connecting shaft connected inside the arc groove, a diffusion plate fixed between the opposite sides of the two connecting shafts, and an adjusting disc fixed at the top of the top connecting shaft.

[0006] As a further description of the above technical solution: The adjusting diffusion mechanism also includes insertion holes evenly opened on the top of the adjusting plate, an L-shaped plate symmetrically fixed on the top of the mounting plate, an insertion rod sliding through the top edge of the L-shaped plate, a circular plate fixed at the bottom of the outer side wall of the insertion rod, a first spring fixed at the top of the circular plate, a pull plate fixed at the top of the insertion rod, a first fastening bolt threaded through the top edge of the pull plate, and a first screw hole opened on the top of the L-shaped plate.

[0007] As a further description of the above technical solution: The upper and lower sides of the diffuser plate are attached to the opposite sides of the two mounting plates, and the outer side wall of the connecting shaft is attached to the outer side wall of the arc groove.

[0008] As a further description of the above technical solution: The top of the first spring is fixedly connected to the top of the inner sidewall of the L-shaped plate, and the first spring is sleeved on the outer sidewall of the insertion rod.

[0009] As a further description of the above technical solution: The first fastening bolt is screwed into the inside of the first screw hole, and the diameter of the insertion rod is equal to the diameter of the insertion hole.

[0010] As a further description of the above technical solution: The storage mechanism includes U-shaped blocks symmetrically fixed to the outer wall of the top mounting plate. A shell is fixed to the top outer side of the diffuser plate. Slide rods are symmetrically fixed between the upper and lower sides of the inner cavity of the shell. A slide plate slides on the outer side of the slide rods. A second spring is symmetrically fixed to the bottom of the slide plate. A locking rod is fixed to the top center of the slide plate. A connecting seat is fixed to the bottom center of the slide plate. A rotating shaft is connected through one bottom side of the shell and is rotatably connected to the shell. A turntable is fixed to one end of the rotating shaft and a knob is fixed to the other end. A connecting rod is fixed to one side of the turntable. A connecting rod is rotatably connected to the outer wall of the connecting rod. A second screw hole is opened on one bottom side of the shell. A second fastening bolt is screwed through one side of the knob.

[0011] As a further description of the above technical solution: The bottom end of the second spring is fixed to the bottom of the inner cavity of the housing, and the second spring is sleeved on the outside of the slide rod.

[0012] As a further description of the above technical solution: The top end of the connecting rod rotates inside the connecting seat, the second fastening bolt is screwed into the inside of the second screw hole, the locking rod passes through the top of the housing, and the locking rod is slidably connected to the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This small speaker with an arc-shaped sound wave diffusion panel, by pulling the pull plate, moves the plug rod, causing the circular plate to move and compress the first spring, simultaneously moving the plug rod out of the socket. Rotating the diffusion plate adjusts the angle of the diffusion plate, aligning the plug rod with the socket. Loosening the pull plate, through the reset of the first spring, causes the plug rod to be embedded in the socket, thus fixing the diffusion plate. This facilitates adjustment of the diffusion plate's angle, making it easier to diffuse the sound emitted by the speaker, resulting in better sound effects. It also allows for easy adjustment according to the user's needs, enhancing the practicality of the device.

[0014] This small speaker with an arc-shaped sound diffusion panel works by removing the plug from the socket, causing the connecting shaft to move inside the arc groove. Then, by loosening the plug and turning the knob, the shaft rotates, causing the turntable to deflect the connecting rod, which in turn deflects the connecting rod, causing the connecting seat to descend. This lowers the sliding plate, compressing the second spring and simultaneously lowering the locking rod. Afterward, rotating the diffusion plate allows it to fit against the speaker body. Loosening the knob allows the second spring to reset, causing the sliding plate to reset the locking rod, which then embeds itself in the U-shaped block. This facilitates folding and storage of the diffusion plate, reducing its bulk during transport and improving the device's practicality. Attached Figure Description

[0020] This utility model provides a small speaker with an arc-shaped sound wave diffusion panel, which facilitates the diffusion of sound emitted by the speaker body, improving sound quality. It also allows for easy adjustment according to user needs, enhancing the practicality of the device. Please refer to [link / reference]. Figure 1 The speaker body 1 is included. Mounting plates 2 are fixed on the upper and lower sides of the speaker body 1. The top of the mounting plates 2 is symmetrically provided with arc grooves 3. Please refer to it again. Figure 1 The outer side of the speaker body 1 is symmetrically connected with an adjustment and diffusion mechanism 4, and the outer side of the speaker body 1 is connected with a storage mechanism 5. Please refer to it again. Figure 4 The adjusting diffusion mechanism 4 includes a connecting shaft 401 connected inside the arc groove 3, a diffusion plate 402 fixed between the opposite sides of the two connecting shafts 401, and an adjusting disc 403 fixed at the top of the top connecting shaft 401.

[0021] Please refer to it again. Figure 4 The regulating diffusion mechanism 4 also includes insertion holes 404 evenly opened on the top of the regulating plate 403, and L-shaped plates 405 are symmetrically fixed on the top of the top mounting plate 2. Insertion rods 406 slide through the top edge of the L-shaped plate 405. Please refer to it again. Figure 4 A circular plate 407 is fixed to the bottom of the outer side wall of the insertion rod 406, a first spring 408 is fixed to the top of the circular plate 407, and a pull plate 409 is fixed to the top of the insertion rod 406. Please refer to it again. Figure 4 The top edge of the pull plate 409 is threaded with a first fastening bolt 410, and the top of the L-shaped plate 405 is provided with a first screw hole 411.

[0022] In summary, by pulling the pull plate 409, the insertion rod 406 moves, causing the circular plate 407 to move and press the first spring 408. At the same time, the insertion rod 406 moves out of the insertion hole 404. By rotating the diffuser plate 402 and adjusting its angle, the insertion rod 406 is aligned with the insertion hole 404. Loosening the pull plate 409 allows the first spring 408 to reset, causing the insertion rod 406 to be embedded in the insertion hole 404, thus fixing the diffuser plate 402. This facilitates adjustment of the diffuser plate 402's angle, improves the diffusion of sound emitted by the speaker body 1, enhances the sound effect, and allows for easy adjustment according to the user's needs, improving the device's practicality.

[0023] Please refer to it again. Figure 1 The upper and lower sides of the diffuser plate 402 are attached to the opposite sides of the two mounting plates 2, and the outer side wall of the connecting shaft 401 is attached to the outer side wall of the arc groove 3.

[0024] Please refer to it again. Figure 4 The top of the first spring 408 is fixedly connected to the top of the inner side wall of the L-shaped plate 405, and the first spring 408 is sleeved on the outer side wall of the insert rod 406.

[0025] Please refer to it again. Figure 4 The first fastening bolt 410 is screwed into the inside of the first screw hole 411, and the diameter of the insertion rod 406 is equal to the diameter of the insertion hole 404.

[0026] Please refer to it again. Figure 5 and Figure 6The storage mechanism 5 includes a U-shaped block 501 symmetrically fixed to the outer wall of the top mounting plate 2; a housing 502 is fixed to the top outer side of the diffuser plate 402; a sliding rod 503 is symmetrically fixed between the upper and lower sides of the inner cavity of the housing 502; a sliding plate 504 slides on the outer side of the sliding rod 503; a second spring 505 is symmetrically fixed to the bottom of the sliding plate 504; a locking rod 506 is fixed to the top center of the sliding plate 504; and a connecting seat 507 is fixed to the bottom center of the sliding plate 504. A rotating shaft 508 is connected through one side of the bottom of the housing 502, and the rotating shaft 508 is rotatably connected to the housing 502. A turntable 509 is fixed at one end of the rotating shaft 508, and a knob 510 is fixed at the other end of the rotating shaft 508. A connecting rod 511 is fixed on one side of the turntable 509, and a connecting rod 512 is rotatably connected to the outer side wall of the connecting rod 511. A second screw hole 513 is opened on one side of the bottom of the housing 502, and a second fastening bolt 514 is screwed through one side of the knob 510.

[0027] Please refer to it again. Figure 5 The bottom end of the second spring 505 is fixed to the bottom of the inner cavity of the outer shell 502, and the second spring 505 is sleeved on the outside of the slide rod 503.

[0028] Please refer to it again. Figure 5 The top end of the connecting rod 512 rotates inside the connecting seat 507, the second fastening bolt 514 is screwed into the inside of the second screw hole 513, the locking rod 506 passes through the top of the housing 502, and the locking rod 506 is slidably connected to the housing 502.

[0029] In summary, by removing the insertion rod 406 from the insertion hole 404, the connecting shaft 401 moves within the arc groove 3. Then, by loosening the insertion rod 406 and rotating the knob 510, the rotating shaft 508 rotates, causing the turntable 509 to deflect the connecting rod 511, which in turn causes the connecting rod 512 to deflect, causing the connecting seat 507 to descend, and the sliding plate 504 to descend, pressing the second spring 505. Simultaneously, the locking rod 506 descends. Then, the diffuser plate 402 is rotated to fit against the speaker body 1. By loosening the knob 510 and resetting the second spring 505, the sliding plate 504 drives the locking rod 506 to reset, so that the locking rod 506 is embedded in the U-shaped block 501. This facilitates the folding and storage of the diffuser plate 402, avoiding the need for large volumes during movement and transportation, and improving the practicality of the device.

[0030] In practical use, when adjusting the sound diffusion effect of the speaker body 1, those skilled in the art pull the pull plate 409, causing the insertion rod 406 to move, which in turn moves the circular plate 407, compressing the first spring 408. Simultaneously, the insertion rod 406 moves out of the insertion hole 404. The diffuser plate 402 is rotated to adjust its angle, aligning the insertion rod 406 with the insertion hole 404. Loosening the pull plate 409 allows the first spring 408 to reset, causing the insertion rod 406 to be embedded in the insertion hole 404, thus fixing the diffuser plate 402. This facilitates adjusting the angle of the diffuser plate 402 and improves the diffusion of sound emitted by the speaker body 1. When it is necessary to retract the diffuser plate 402, the insertion rod 406 is removed. In the socket 404, the connecting shaft 401 moves inside the arc groove 3. Then, the plug rod 406 is loosened, and the knob 510 is turned to drive the rotating shaft 508 to rotate. This causes the turntable 509 to drive the connecting rod 511 to deflect, which in turn causes the connecting rod 512 to deflect, causing the connecting seat 507 to drop. This causes the sliding plate 504 to drop, pressing the second spring 505 and simultaneously causing the locking rod 506 to drop. Then, the diffuser plate 402 is rotated to fit against the speaker body 1. The knob 510 is loosened, and the second spring 505 resets, causing the sliding plate 504 to drive the locking rod 506 to reset. The locking rod 506 is then embedded in the U-shaped block 501, making it convenient to fold and store the diffuser plate 402.
