[0034] like Figure 1-5 As shown, an embodiment of this utility model provides a speaker enclosure that integrates a grille and a front shell, including a front shell 1, a speaker 2, and a rear shell 3. The front shell 1 is a hollow structure, with a first mounting base 4 on its inner side. One side of the first mounting base 4 forms a sound-permeable grille 5, and the other side forms a sound guide 6. The speaker 2 is securely mounted to the first mounting base 4, with its opening facing the sound-permeable grille 5 and its front end face pressed against the sound guide 6. The rear shell 3 is securely connected to the front shell 1 and forms a sound chamber 7, with the speaker 2 located inside the sound chamber 7. By integrating the front shell and grille into a single design with a sound-permeable grille 5 in the front shell 1, the speaker enclosure and grille are reduced in size, reducing production and installation steps. This not only lowers the speaker's production cost but also maximizes the acoustic cavity space required for sounding, thereby improving the speaker's sound quality.

[0035] Specifically, in this embodiment, such as Figure 1 and 3As shown, the front housing 1 is a semi-enclosed hollow shell structure with an opening on its rear side. The front housing 1 can be integrally injection molded from plastic. A first mounting base 4 is provided on the inner side of the front housing 1. The first mounting base 4 is used to securely mount the speaker 2, which is used for sound production in the speaker enclosure. Multiple first threaded posts 8 are provided on the first mounting base 4, arranged evenly around the circumference. Multiple first through holes 9 are provided on the speaker 2 corresponding to the first threaded posts 8. Screws pass through the first through holes 9 and are fastened to the first threaded posts 8, thereby securing the speaker 2 to the first mounting base 4. The outer side of the first mounting base 4 forms a sound-permeable mesh frame 5, and the inner side forms a sound guide portion 6. The sound-permeable mesh frame 5 has a mesh structure, and the sound guide portion 6 has a tubular structure. When the speaker 2 is mounted on the first mounting base 4, the opening of the speaker 2 faces the sound-permeable mesh frame 5, and the front end face of the speaker 2 is pressed against the end face of the sound guide portion 6. The sound guide portion 6 and the sound-permeable mesh frame 5 guide the sound from the speaker 2 through the sound-permeable mesh frame 5 to propagate the sound outside the speaker enclosure. Furthermore, such as Figure 1 and 4 As shown, the rear housing 3 has a cover structure. The rear housing 3 can also be integrally injection molded from plastic. Multiple first countersunk holes 10 are symmetrically arranged on the rear housing 3. Multiple second threaded posts 11 are provided on the front housing 1 corresponding to the first countersunk holes 10. Screws pass through the first countersunk holes 10 and are fastened to the second threaded posts 11, thereby securing the rear housing 3 to the rear side of the front housing 1 and sealing the front housing 1 to form a sound chamber 7. The speaker 2 is located inside the sound chamber 7, which is used to adjust the sound quality of the speaker. Generally speaking, speakers with a larger sound chamber 7 have better sound quality. The speaker of this invention integrates the front housing and grille design of conventional speaker technology into a single component, namely, a front housing 1 with a sound-permeable grille 5. The integration of the front housing and grille reduces the volume and manufacturing and installation processes, not only lowering the production cost of the speaker but also maximizing the acoustically required sound chamber space, i.e., increasing the volume of the sound chamber 7 and improving the sound quality of the speaker.

[0036] Furthermore, in this embodiment, as Figure 1As shown, the speaker also includes sealing cotton 12. A first receiving groove 13 is provided at the rear end of the front housing 1. The sealing cotton 12 is embedded in the first receiving groove 13 for installation, and the rear housing 3 presses the sealing cotton 12 against it. Preferably, the rear housing 3 is provided with a pressing groove 14, which is engaged with the first receiving groove 13 to press the sealing cotton 12 against it. Specifically, to better seal the speaker, a sealing cotton 12 is used to seal the assembly of the front housing 1 and the rear housing 3. The rear end of the front housing 1 has an annular first receiving groove 13 into which the sealing cotton 12 is embedded. The front side of the rear housing 3 has an annular pressing groove 14, which functions as a surrounding panel. When the rear housing 3 is assembled, the pressing groove 14 engages with the first receiving groove 13 to press the sealing cotton 12 against it, thereby achieving a complete seal of the speaker with good sealing effect and preventing sound leakage.

[0037] Furthermore, in this embodiment, as Figure 1 and 5 As shown, the speaker also includes a silicone wire clip 15. A second mounting base 16 is provided at the rear end of the front housing 1. The second mounting base 16 is located on the first receiving groove 13. The silicone wire clip 15 is embedded in the second mounting base 16 for installation. The rear housing 3 simultaneously presses the silicone wire clip 15 with a pressing groove 14. Preferably, the pressing groove 14 is provided with an opening groove 17, and the silicone wire clip 15 is provided with a relief groove 18. The opening groove 17 is engaged with the relief groove 18 to press the silicone wire clip 15. Specifically, the speaker generally needs to be connected to the speaker 2 with wires, and the position where the wires pass through the speaker housing also needs to be sealed. In order to better seal the speaker, the speaker is also equipped with a silicone wire clip 15. The silicone wire clip 15 is provided with a wire hole 19. The wires pass through the wire hole 19 and enter the sound chamber 7 and are electrically connected to the speaker 2. The wires are tightly assembled with the silicone wire clip 15. A second mounting base 16 is provided on the first receiving groove 13 of the front housing 1. The shape of the second mounting base 16 is adapted to the shape of the silicone wire clip 15, and the silicone wire clip 15 is stably installed on the second mounting base 16. The pressing part 14 has an opening groove 17 corresponding to the position of the second mounting base 16. A relief groove 18 is provided around the silicone wire clip 15. When the rear housing 3 is fastened to the front housing 1, the edge of the opening groove 17 is inserted into the relief groove 18 and presses the silicone wire clip 15. After being pressed, the silicone wire clip 15 will produce a certain deformation and compress the wire hole 19. The silicone wire clip 15 further clamps the wire to form a seal, thereby achieving an overall seal of the speaker. The sealing effect is good and prevents sound leakage.

[0038] Furthermore, in this embodiment, as Figure 1 and 2As shown, the speaker also includes a dustproof film 20, which is attached to the outer surface of the front housing 1. Specifically, to improve the speaker's appearance, the speaker is equipped with a dustproof film 20, which can be made of an elastic fabric material. The dustproof film 20 covers the outer surface of the front housing 1. When the rear housing 3 is installed, the rear housing 3 and the front housing 1 simultaneously clamp the dustproof film 20, so that the dustproof film 20 can be firmly attached to the outer surface of the front housing 1 and can be moved slightly, which can effectively improve the speaker's appearance and enhance the user experience.

[0039] Furthermore, in this embodiment, as Figure 1 and 4 As shown, the rear housing 3 has a support leg 21 extending from the lower end of the rear housing 3, supporting the speaker. Preferably, the support leg 21 has an L-shaped structure, including a bent portion 22 and a horizontal portion 23. The bent portion 22 extends into the lower part of the front housing 1, and the horizontal portion 23 supports the speaker. Specifically, to facilitate speaker support, a support leg 21 extends from the bottom of the rear housing 3, integrally formed with the rear housing 3, allowing the support leg 21 to stably support the rear housing 3 and thus the speaker. The support leg 21 has an L-shaped structure, with the upper part being the bent portion 22 and the lower part being the horizontal portion 23. The interiors of the bent portion 22 and the horizontal portion 23 are hollow structures. The bent portion 22 connects to the lower end of the rear housing 3 and extends towards the front of the rear housing 3, allowing the bent portion 22 to extend into the lower rear side of the front housing 1, which is beneficial for miniaturizing the speaker. The bottom surface of the horizontal part 23 is flat and arranged in a horizontal direction. The horizontal part 23 is used to support the rear housing 3. When the speaker is placed on the table, the horizontal part 23 contacts the table and supports the speaker. In this embodiment, the L-shaped hollow structure of the support foot 21 makes the speaker look stylish and beautiful, and saves materials used in the production of the support foot 21.

[0040] The speaker that implements this utility model integrates the mesh frame and the front shell into one, and designs the front shell and the mesh frame into a front shell 1 with a sound-permeable mesh frame 5. After the front shell and the mesh frame are integrated, the volume is reduced, the production and installation steps are reduced, which can not only reduce the production cost of the speaker, but also maximize the acoustic cavity space required for acoustics, improve the sound quality of the speaker, and have better market benefits.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
