Description

Technical Field

[0001] This utility model relates to the technical field of loudspeakers, and in particular to a speaker enclosure fixing and sealing structure and a speaker enclosure. Background Technology

[0002] A speaker enclosure typically consists of components such as a speaker enclosure, a speaker, and a crossover. The speaker and the crossover are both located inside the speaker enclosure. The speaker and the crossover require external power cables or audio cables, which are run through the speaker enclosure.

[0003] To maintain stable connections between the wires and the speaker and crossover, and to seal the wire penetration holes in the speaker enclosure to ensure optimal sound quality, the wires typically need to be secured relative to the enclosure. Currently, the common methods are: directly injecting glue into the flat end of the wire lead on the side of the enclosure, or creating a glue reservoir on the side of the wire lead. Due to the enclosure structure, these reservoirs are usually shallow. Glue is injected into the reservoir to secure the wires relative to the enclosure and to seal both the wires and the enclosure.

[0004] However, the above-mentioned fixing structure design has the following defects: First, due to insufficient space for the glue, the sealing and fixing effect of the glue is not good. The glue is easy to separate and fall off from the speaker shell during transportation or assembly, resulting in the speaker failing to meet the sealing requirements and affecting the sound quality of the speaker. Second, since the glue injection position is located on the side of the speaker shell where the wires are led out, the wires will twist during use. The twisted wires will generate torque on the glue, accelerating the process of the glue separating and falling off from the speaker shell. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a speaker shell fixing and sealing structure and a speaker shell, which can effectively reduce the risk of the colloid separating and falling off from the speaker shell.

[0006] To solve the above-mentioned technical problems, the speaker shell fixing and sealing structure provided by this utility model adopts the following technical solution:

[0007] A speaker enclosure fixing and sealing structure includes a lead wire side plate disposed on the speaker enclosure. The lead wire side plate is used to pass through the lead wire. A glue storage box is disposed on the inner side of the lead wire side plate. The lead wire passes through the glue storage box. One side wall of the glue storage box is open and the opening direction is perpendicular to the lead wire's exit direction. A glue injection hole is opened on the surface of the speaker enclosure near the opening of the glue storage box. The axial projection of the outline edge of the glue injection hole opening is located inside the glue storage box.

[0008] By adopting the above technical solution, glue is applied into the injection hole, flowing into the glue reservoir until it is full. The fluidity of the glue seals the wire insertion opening on the lead plate, ensuring a sealed speaker enclosure. Furthermore, the glue in the reservoir secures the wires, preventing twisting of the wire shell during use and ensuring stable connection between the wires and internal components. The glue reservoir and injection hole design, with the glue located inside the speaker enclosure, significantly reduces the risk of the glue separating from the enclosure due to wire twisting, thus improving the speaker's performance. Moreover, since the glue is injected from top to bottom through the injection hole, automated glue application and sealing can be achieved, improving efficiency.

[0009] Optionally, the cross-sectional profile of the inner wall of the injection hole is trapezoidal, and the small end of the injection hole faces the glue storage box.

[0010] By adopting the above technical solution, the flow direction and flow area of ​​the glue are guided and restricted by the trapezoidal contour of the glue injection hole, so that the glue flows into the center of the glue storage box and then disperses. This avoids the glue flowing to other parts through the edge of the glue injection hole and then falling down, which would cause the glue to fall outside the glue storage box or the edge of the opening. This achieves a large glue injection surface while ensuring the accuracy of glue injection and further improves glue injection efficiency.

[0011] Optionally, a boss is provided at the bottom of the glue storage box.

[0012] By adopting the above technical solution, the boss can support and limit the colloid in the colloid storage box, which can enhance the strength of the colloid and better resist the torque generated by the twisting of the wire, thereby reducing the risk of the colloid separating from the inner wall of the colloid storage box.

[0013] Secondly, the speaker shell provided by this utility model adopts the following technical solution:

[0014] A speaker enclosure includes the aforementioned speaker enclosure glue storage structure, a speaker upper shell, and a speaker lower shell that is mounted on and covered by the speaker upper shell. The lead wire side plate is a side plate on the speaker upper shell through which lead wires pass, and the glue injection hole is opened in the speaker lower shell.

[0015] Optionally, both the side wall of the glue storage box and the lead wire side plate are provided with placement openings, and the inner wall of the placement opening is U-shaped with the U-shaped opening facing the lower shell of the speaker.

[0016] By adopting the above technical solution, the wire is first placed in the placement port, and then the upper and lower shells of the speaker are covered and fused together, which improves the processing convenience of connecting and leading out the wire.

[0017] In summary, this utility model has at least one of the following beneficial technical effects:

[0018] 1. By designing the glue storage box and glue injection hole, the glue is located inside the speaker shell, which significantly reduces the risk of the glue separating from the speaker shell due to wire twisting, thereby improving the quality of the speaker's use;

[0019] 2. Because the glue is injected from top to bottom through the injection hole, the glue injection and sealing operation can be automated, thereby improving the glue injection efficiency;

[0020] 3. The flow direction and flow area of ​​the glue are guided and restricted by the trapezoidal contour of the glue injection hole, thereby preventing the glue from flowing to other parts through the edge of the injection hole and then falling back down, which would cause the glue to fall outside the glue storage box or the edge of the opening. This achieves a large glue injection surface while ensuring the accuracy of glue injection, and further improves glue injection efficiency. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0026] This utility model discloses a speaker shell, referring to... Figure 1 The speaker enclosure includes an upper speaker enclosure 5, a lower speaker enclosure 6, and a speaker enclosure fixing and sealing structure. The lower speaker enclosure 6 is covered and fused to the upper speaker enclosure 5.

[0027] Reference Figure 1 and Figure 2 The speaker enclosure's fixed sealing structure includes a lead wire side plate 1, which is the side plate of the speaker's upper shell 5 used for passing through the lead wires 8. A glue storage box 2 is provided on the inner side of the lead wire side plate 1. The glue storage box 2 is a hollow rectangular body, and the lead wires 8 pass through the two opposite side walls of the glue storage box 2.

[0028] Reference Figure 1 , Figure 2 and Figure 3The glue storage box 2 has an opening on one side wall facing the lower shell 6 of the speaker. The opening of the glue storage box 2 is perpendicular to the lead-out direction of the wire 8 and faces the lower shell 6 of the speaker. The lower shell 6 of the speaker has a glue injection hole 3, and the axial projection of the outline edge of the glue injection hole 3 is located inside the glue storage box 2.

[0029] Glue is applied into the injection hole 3, flowing into the glue reservoir 2 until it is full. The fluidity of the glue seals the opening for the wire 8 on the lead plate 1, ensuring a sealed speaker enclosure. The glue in the reservoir 2 also secures the wire 8, preventing it from twisting during use and affecting the connection stability between the wire 8 and internal components. The reservoir 2 and injection hole 3 ensure the glue is located inside the speaker enclosure, significantly reducing the risk of separation and detachment due to wire twisting, thus improving the speaker's performance. Furthermore, since the glue is injected from top to bottom through the injection hole 3, automated sealing can be achieved, improving injection efficiency.

[0030] Reference Figure 3 The inner wall of the injection hole 3 has a trapezoidal cross-sectional profile, with the smaller end of the injection hole 3 facing the glue storage box 2. The trapezoidal profile of the injection hole 3 guides and restricts the flow direction and flow area of ​​the glue, allowing the glue to flow into the center of the glue storage box 2 and then disperse. This prevents the glue from flowing to other parts along the edge of the injection hole 3 and then falling back down, thus avoiding the problem of glue falling outside the glue storage box 2 or onto the opening edge. This achieves a large injection surface while ensuring the accuracy of glue injection, further improving the glue injection efficiency.

[0031] Reference Figure 2 A boss 4 is provided at the bottom of the glue storage box 2. The boss 4 is located below the wire 8 and extends along the axis of the wire 8 in its length direction. The boss 4 can support and limit the glue in the glue storage box 2, which can enhance the strength of the glue and better resist the torque generated by the twisting of the wire 8 on the glue, thereby reducing the risk of the glue separating from the inner wall of the glue storage box 2.

[0032] Reference Figure 2 The storage box 2 and the lead wire side plate 1 both have placement openings 7. The inner wall of the placement opening 7 is U-shaped and the U-shaped opening faces the lower shell 6 of the speaker. The wire 8 is first placed in the placement opening 7, and then the upper shell 5 and the lower shell of the speaker are closed and fused together, which improves the processing convenience of connecting and leading out the wire 8.

[0033] The embodiment of this invention provides a speaker shell fixing and sealing structure and its implementation principle as follows: Adhesive is applied into the injection hole 3, flowing into the glue storage box 2. The glue storage box 2 is filled with glue, and the fluidity of the glue seals the through-hole of the wire 8 on the lead wire side plate 1, ensuring a sealed speaker. Furthermore, the glue in the storage box 2 can fix the wire 8, preventing the outer part of the wire 8 from twisting during use, which could affect the connection stability between the wire 8 and internal components. By using the glue storage box 2 and the injection hole 3, the glue is located inside the speaker shell, significantly reducing the risk of the glue separating from the speaker shell due to the twisting of the wire 8, thereby improving the speaker's performance.
