Integrated sealing structure for speaker wall mounting holes

Abstract

This utility model relates to the field of speaker technology, and in particular to an integrated sealing structure for a wall-mounting hole of a speaker. It includes a speaker shell with a sound cavity, and a plastic baffle integrally injection-molded on the inner surface of the speaker shell. The plastic baffle and the inner surface of the speaker shell form a pull-out groove, which is not electrically connected to the sound cavity. The speaker shell has a wall-mounting hole penetrating its inner and outer surfaces at the pull-out groove location, and the wall-mounting hole is electrically connected to the pull-out groove. Compared with the prior art, by integrally injection-molding the plastic baffle on the inner surface of the speaker shell and forming a pull-out groove that is not electrically connected to the sound cavity; and by electrically connecting the wall-mounting hole to the pull-out groove but not to the sound cavity, it ensures that the wall-mounting hole is completely non-conductively connected to the sound cavity. This prevents sound leakage from the sound cavity through the wall-mounting hole, eliminates sound distortion and reduced sound propagation efficiency during speaker use, and ensures that the sound quality of the speaker is not degraded due to sound leakage, thus guaranteeing the reliability of the speaker and the user experience.

Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to an integrated sealing structure for wall mounting holes of speakers. Background Technology

[0002] In related technologies, the design of wall mounting holes for speakers or electronic products typically requires drilling holes in the casing, then designing the internal structure, adding a sealing cap and sealing it with screws, or using foam to cover the sealing groove and then applying adhesive for sealing. These additional parts (such as sealing caps, screws, foam, etc.) increase manufacturing costs. For speaker products, the installation and sealing of sealing caps may be unstable, and leaks are prone to occur. If sound leakage occurs from these poorly sealed wall mounting holes inside the speaker cavity, it will cause sound distortion and sound energy loss during speaker operation, seriously affecting the reliability of the speaker.

[0003] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an integrated sealing structure for wall mounting holes in speakers, effectively solving the technical defects of high manufacturing costs and sound leakage caused by wall mounting holes in the speaker housing in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated sealing structure for a wall mounting hole of a speaker, comprising a speaker housing with a sound cavity, wherein a plastic baffle is integrally injection molded on the inner surface of the speaker housing, the plastic baffle can form a core-pulling groove with the inner surface of the speaker housing, the core-pulling groove is not electrically connected to the sound cavity; the speaker housing is provided with a wall mounting hole penetrating its inner and outer surfaces at the position of the core-pulling groove, the wall mounting hole is electrically connected to the core-pulling groove.

[0006] The beneficial effect of the integrated sealing structure for wall mounting holes of speakers provided by this utility model is that, compared with the prior art, by integrally injection molding a plastic enclosure on the inner surface of the speaker shell and forming a core-pulling groove that is not electrically connected to the sound cavity, the wall mounting hole is electrically connected to the core-pulling groove, while the wall mounting hole is not electrically connected to the sound cavity. Firstly, by using an integrally injection-molded plastic enclosure as a sealing structure for the wall mounting hole, it can be ensured that the wall mounting hole is completely disconnected from the sound cavity, and the sound cavity will not leak sound from the wall mounting hole. This ensures that there will be no sound distortion or reduced sound propagation efficiency during the use of the speaker, and the sound quality of the speaker will not be reduced due to sound leakage, thus ensuring the reliability of the speaker and the user's experience. Secondly, since the plastic enclosure structure is directly injection molded, there is no need to add sealing parts to seal the wall mounting holes. This not only reduces the purchase cost of parts and the labor cost of assembly, but also improves the assembly efficiency of the speaker.

[0007] As a preferred embodiment, the speaker housing includes at least a rear plastic panel, an upper plastic panel integrally formed on top of the rear plastic panel, and a lower plastic panel integrally formed on bottom of the rear plastic panel, wherein the upper plastic panel and the lower plastic panel both extend forward and are arranged parallel to each other.

[0008] As a preferred embodiment, a left plastic plate is provided at the left end of the upper plastic plate, lower plastic plate and rear plastic plate, and a right plastic plate is provided at the right end of the upper plastic plate, lower plastic plate and rear plastic plate. The upper plastic plate, lower plastic plate, rear plastic plate, left plastic plate and right plastic plate enclose a sound cavity with the opening facing forward.

[0009] As a preferred embodiment, the plastic fencing is integrally injection molded on the front surface of the rear plastic panel. The bottom of the plastic fencing extends downward and is integrally formed with the upper surface of the lower plastic panel. The plastic fencing, the rear plastic panel, and the lower plastic panel form a core-pulling groove, which extends downward through the lower surface of the lower plastic panel to form a core-pulling opening.

[0010] As a preferred embodiment, the wall-mounting hole penetrates the front and rear surfaces of the rear plastic sheet and is connected to the core-pulling groove. The cross-sectional dimension of the wall-mounting hole is smaller than that of the core-pulling groove.

[0011] As a preferred embodiment, the wall mounting hole includes a small round hole portion and a large round hole portion, with the small round hole portion located at the upper end of the large round hole portion and the small round hole portion communicating with the large round hole portion.

[0012] As a preferred option, the thickness of the plastic fencing is less than the thickness of the rear plastic panel, and the front surface of the plastic fencing is parallel to the front surface of the rear plastic panel.

[0013] As a preferred embodiment, the thickness of the rear plastic sheet is the same as the thickness of the upper and lower plastic sheets, or the thickness of the rear plastic sheet is greater than the thickness of the upper and lower plastic sheets.

[0014] As a preferred option, there are two wall-mounting holes, with the two wall-mounting holes spaced horizontally on the rear plastic panel and at the same height; the plastic fencing is configured according to the number of wall-mounting holes.

[0015] As a preferred embodiment, the rear surface of the rear plastic panel is provided with an abutment protrusion that extends rearward and is located on the left or right side of the wall mounting hole. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 5 The integrated sealing structure 100 for wall mounting holes of a speaker, provided in the embodiments of this application, will now be described. The integrated sealing structure 100 for wall mounting holes of a speaker includes: a speaker housing 10.

[0025] The speaker housing 10 has a sound cavity 16 for installing the air duct and speaker assembly; the inner surface of the speaker housing 10 is integrally injection molded with a plastic baffle 20, which can form a core-pulling groove 21 with the inner surface of the speaker housing 10, and the core-pulling groove 21 is not electrically connected to the sound cavity 16; the speaker housing 10 has a wall-mounting hole 30 penetrating its inner and outer surfaces at the position of the core-pulling groove 21, and the wall-mounting hole 30 is electrically connected to the core-pulling groove 21.

[0026] Specifically, a plastic enclosure 20 is integrally injection molded on the inner surface of the speaker housing 10, forming a core-pulling groove 21 that is not electrically connected to the sound cavity 16; the wall mounting hole 30 is electrically connected to the core-pulling groove 21, while the wall mounting hole 30 is not electrically connected to the sound cavity 16. Firstly, by using the integrally injection-molded plastic enclosure 20 as a sealing structure for the wall mounting hole 30, it can be ensured that the wall mounting hole 30 is completely disconnected from the sound cavity 16, and the sound cavity 16 will not leak sound from the wall mounting hole 30. This ensures that there will be no sound distortion or reduced sound propagation efficiency during the use of the speaker, and the sound quality of the speaker will not be reduced due to sound leakage, thus ensuring the reliability of the speaker and the user's experience. Secondly, since the plastic enclosure 20 is directly injection molded, there is no need to add sealing parts to seal the wall mounting hole 30. This not only reduces the purchase cost of parts and the labor cost of assembly, but also improves the assembly efficiency of the speaker.

[0027] In some embodiments, the speaker housing 10 includes at least a rear plastic plate 11, an upper plastic plate 12 integrally formed on the top of the rear plastic plate 11, and a lower plastic plate 13 integrally formed on the bottom of the rear plastic plate 11. The upper plastic plate 12 and the lower plastic plate 13 both extend forward and are arranged parallel to each other. A left plastic plate 14 is provided at the left end of the upper plastic plate 12, the lower plastic plate 13, and the rear plastic plate 11, and a right plastic plate 15 is provided at the right end of the upper plastic plate 12, the lower plastic plate 13, and the rear plastic plate 11. The upper plastic plate 12, the lower plastic plate 13, the rear plastic plate 11, the left plastic plate 14, and the right plastic plate 15 enclose a forward-facing sound cavity 16.

[0028] Understandably, the speaker housing 10 also includes a front cover (not shown in the figure), which is installed on the front end of the sound cavity 16 to complete the installation of the entire speaker.

[0029] Specifically, the plastic enclosure 20 is integrally injection molded on the front surface of the rear plastic panel 11. The bottom of the plastic enclosure 20 extends downward and is integrally formed with the upper surface of the lower plastic panel 13. The plastic enclosure 20, the rear plastic panel 11 and the lower plastic panel 13 form a core-pulling groove 21. The core-pulling groove 21 extends downward through the lower surface of the lower plastic panel 13 to form a core-pulling opening 22.

[0030] Preferably, at least the surface of the core-pulling groove 21 is gradually widened from top to bottom, so that after the speaker housing 10 and the plastic enclosure 20 are integrally injection molded, the molded insert can smoothly exit from the core-pulling groove 21.

[0031] In other embodiments, the wall-mounting hole 30 penetrates the front and rear surfaces of the rear plastic sheet 11 and is conductively connected to the core-pulling groove 21. The cross-sectional dimension of the wall-mounting hole 30 is smaller than the cross-sectional dimension of the core-pulling groove 21, so that the wall-mounting hole 30 is only conductively connected to the core-pulling groove 21. The wall-mounting hole 30 includes a small circular hole portion 31 and a large circular hole portion 32. The small circular hole portion 31 is located at the upper end of the large circular hole portion 32, and the small circular hole portion 31 communicates with the large circular hole portion 32.

[0032] To suspend the speaker on the support, first, a hook is installed on the support. Then, the speaker is brought close to the hook, allowing the hook to first engage in the large round hole 32. As the speaker moves downwards, the hook eventually engages in the small round hole 31, thus completing the speaker suspension. The pull-out groove 21 provides clearance for the hook during insertion into the wall mounting hole 30, allowing it to snap into the inner surface of the rear plastic panel 11. At this point, the inner surface of the rear plastic panel 11 is actually behind the pull-out groove 21, which is enclosed by the plastic enclosure 20.

[0033] Preferably, the thickness of the plastic enclosure 20 is less than the thickness of the rear plastic panel 11, and the front surface of the plastic enclosure 20 is parallel to the front surface of the rear plastic panel 11. The thickness of the rear plastic panel 11 is the same as the thickness of the upper plastic panel 12 and the lower plastic panel 13, or the thickness of the rear plastic panel 11 is greater than the thickness of the upper plastic panel 12 and the lower plastic panel 13. This structure can reduce the thickness of the plastic enclosure 20, thus occupying a smaller area of ​​the sound cavity 16, which facilitates the miniaturization of the speaker housing 10.

[0034] In some embodiments, there are two wall-mounting holes 30, spaced apart on the left and right sides of the rear plastic panel 11, and both holes are at the same height. The plastic enclosure 20 is configured according to the number of wall-mounting holes 30. The rear surface of the rear plastic panel 11 is provided with an abutment protrusion 17, which extends rearward and is located to the left or right of the wall-mounting hole 30. The abutment protrusion 17 is preferably made of elastic plastic. After the hook is inserted into the wall-mounting hole, the abutment protrusion 17 continuously provides a forward elastic force to the speaker, allowing the hook to more securely hold the speaker and preventing it from falling off due to vibration during use.

[0035] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
