Description

Technical Field

[0001] This utility model relates to the field of screen sound generation, specifically to a screen sound generation device. Background Technology

[0002] A screen speaker is a technological component that enables a screen to emit sound. Its purpose is to transmit sound while reducing the number of openings at the top of the screen, thereby helping to increase the screen-to-body ratio and meet the design requirements of devices such as full-screen phones.

[0003] Chinese Patent Publication No. CN221728496U discloses a screen sound-generating device, specifically relating to the field of screen sound generation technology. The device includes a screen with a central frame at its bottom. Inside the central frame is an exciter body for driving screen vibration to generate sound, the vibration direction of which is perpendicular to the screen. Inside the central frame is a mounting mechanism for mounting the exciter body. The mounting mechanism includes a mounting plate fixedly installed at the bottom of the exciter body. A fixing plate is fixedly installed inside the central frame, and the mounting plate is inserted into the fixing plate. Two first connecting plates are fixedly installed on both sides of the mounting plate. An I-shaped mounting block is fixedly connected to the bottom of each of the first connecting plates. The fixing plate has a fixing mechanism for fixing the I-shaped mounting block. This invention not only has fewer installation steps and is simple to operate, but also prevents the mounting plate from shaking during vibration.

[0004] The above-mentioned device also has the following problems when in use: the above-mentioned device requires a second operation to make the installation and connection between the mounting plate and the fixing plate secure, which makes the overall installation process more complicated, and the sound generator parts are small, making it inconvenient to pull the handle afterwards.

[0005] Therefore, it is necessary to invent a screen sound-emitting device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a screen sound-generating device to solve the problem mentioned in the background art that the device requires secondary operation to ensure a firm connection between the mounting plate and the fixing plate, which makes the overall installation process cumbersome, and the small size of the sound-generating parts makes it inconvenient to pull the handle afterwards.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a screen sound-emitting device, comprising an exciter body, an installation plate mounted on the bottom of the exciter body, the installation plate and a fixed plate being movably mounted, and the fixed plate being connected to a middle frame, an installation block being fixedly connected to the outer wall of the installation plate, and an arc-shaped groove being pre-set inside the installation block, further comprising:

[0008] The snap-fit ​​mounting assembly has a mounting cavity inside the fixing plate, which is movably connected to the mounting block. The mounting cavity is connected to a columnar groove, and the snap-fit ​​block is movably mounted inside the columnar groove by a spring. The end of the snap-fit ​​block matches the arc-shaped groove, ensuring the matching installation of the exciter body and the middle frame and facilitating subsequent disassembly. The installation process does not require the use of screws or glue, making installation convenient and quick.

[0009] Preferably, the mounting block consists of a square block and a transverse columnar block fixedly connected to the lower end of the square block. The two ends of the columnar block are spherical, and the spherical ends of the columnar block are attached to the inner sidewall of the mounting cavity to achieve a sliding connection, ensuring the smooth matching and installation of the mounting block and the mounting cavity.

[0010] Preferably, there are two mounting blocks, and the two mounting blocks are symmetrically distributed with reference to the central axis of the mounting plate.

[0011] Preferably, the arc-shaped groove is set inside the square block in the mounting block, and the lower end of the arc-shaped groove is seamlessly connected to the end spherical surface of the columnar block. This allows the mounting block to descend smoothly and match the snap-fit ​​block when the mounting plate is pressed down, thus completing the installation of the exciter body.

[0012] Preferably, the snap-fit ​​block consists of a rod and a hemispherical block fixedly connected to the end of the rod, and the outer surface of the hemispherical block is in contact with the arc groove and the spherical surface of the end of the columnar block in the mounting block to achieve a sliding connection.

[0013] Preferably, the two ends of the spring are fixedly connected to the inner wall of the columnar groove and the end of the snap-fit ​​block without the hemispherical block, respectively. The force applied by the spring makes the snap-fit ​​block match the arc groove, thereby completing the movable connection between the mounting plate and the fixing plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention uses a pressing mounting plate to lower the mounting block and make it contact with the snap-fit ​​block, thus pressing the snap-fit ​​block against the columnar groove. As the mounting block continues to descend, the spherical end of the mounting block leaves the hemispherical end of the snap-fit ​​block. The descent of the mounting block causes the position of the arc-shaped groove to correspond to the position of the hemispherical end of the snap-fit ​​block. At this point, the spring is no longer under external pressure and thus undergoes a reset movement, pressing against the snap-fit ​​block and matching it with the arc-shaped groove. In this way, the mounting plate and the fixing plate are installed. The matching of the arc-shaped groove and the snap-fit ​​block ensures that the snap-fit ​​block is positioned above the transverse columnar block in the mounting block, thus ensuring that the mounting block and the mounting cavity are matched and connected in one step and are more secure.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The screen sound-emitting device shown includes an exciter body 1, a mounting plate 2 installed at the bottom of the exciter body 1, and the mounting plate 2 and the fixing plate 3 are movably mounted. The fixing plate 3 is connected to the middle frame. A mounting block 4 is fixedly connected to the outer wall of the mounting plate 2, and the mounting block 4 has a pre-set arc-shaped groove 5. The device also includes:

[0026] The snap-fit ​​mounting assembly 6 has a mounting cavity 601 inside the fixing plate 3, and the mounting cavity 601 is movably connected to the mounting block 4. The mounting cavity 601 is connected to a columnar groove 602, and the snap-fit ​​block 603 is movably mounted inside the columnar groove 602 by a spring 604. The end of the snap-fit ​​block 603 matches the arc-shaped groove 5, ensuring the matching installation of the exciter body 1 and the middle frame and facilitating subsequent disassembly. Moreover, the installation process does not require the use of screws or glue, making the installation convenient and quick.

[0027] The mounting block 4 consists of a square block and a transverse columnar block fixedly connected to the lower end of the square block. The two ends of the columnar block are spherical, and the two spherical ends of the columnar block are attached to the inner sidewall of the mounting cavity 601 to achieve a sliding connection, ensuring the smooth matching and installation of the mounting block 4 and the mounting cavity 601.

[0028] There are two mounting blocks 4, and the two mounting blocks 4 are symmetrically distributed with reference to the central axis of the mounting plate 2.

[0029] The arc-shaped groove 5 is set inside the square block in the mounting block 4, and the lower end of the arc-shaped groove 5 is seamlessly connected to the end spherical surface of the columnar block. In this way, when the mounting plate 2 is pressed down, the mounting block 4 moves down smoothly and matches the snap-fit ​​block 603 to complete the installation of the exciter body 1.

[0030] The snap-fit ​​block 603 consists of a rod and a hemispherical block fixedly connected to the end of the rod. The outer surface of the hemispherical block is in contact with the arc groove 5 and the spherical surface of the end of the columnar block in the mounting block 4 to achieve a sliding connection.

[0031] The two ends of the spring 604 are fixedly connected to the inner wall of the columnar groove 602 and the end of the snap-fit ​​block 603 without the hemispherical block, respectively. The force applied by the spring 604 makes the snap-fit ​​block 603 match the arc groove 5, thereby completing the movable connection between the mounting plate 2 and the fixing plate 3.

[0032] Working principle: When using a screen sound-generating device, firstly, when it is necessary to install the exciter body 1 and the fixing plate 3, the lower end spherical surface of the mounting block 4 on both sides of the mounting plate 2 is aligned with the cavity opening of the mounting cavity 601, and the mounting plate 2 is pressed down. The mounting block 4 moves down synchronously with the mounting plate 2. The downward movement of the mounting block 4 first contacts the end hemisphere of the locking block 603, and then pushes the locking block 603 towards the interior of the columnar groove 602. At this time, the spring 604 is squeezed by the force generated by the movement of the locking block 603. During the deformation and continuous descent of the mounting block 4, the spherical end of the mounting block 4 leaves the hemispherical end of the snap-fit ​​block 603. As the mounting block 4 descends, the position of the arc groove 5 corresponds to the position of the hemispherical end of the snap-fit ​​block 603. At this time, the spring 604 is no longer subjected to external pressure and thus undergoes a reset movement to abut against the snap-fit ​​block 603 and match the movement of the arc groove 5. After the snap-fit ​​block 603 matches the arc groove 5, it directly abuts against the top of the end of the transverse columnar block in the mounting block 4. In this way, the mounting plate 2 and the fixing plate 3 are installed and the installation is relatively firm, without the need for accessories such as glue and screws.

[0033] When it is necessary to separate the mounting plate 2 from the fixing plate 3, the mounting plate 2 is pushed upwards and the mounting block 4 moves upwards simultaneously. The arc groove 5 in the mounting block 4 is seamlessly connected to the end spherical surface of the mounting block 4. This ensures that the mounting block 4 moves upwards smoothly through the end hemispherical block of the elastic snap-fit ​​block 603, and the separation is also more convenient.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
