Description

Technical Field

[0001] The present invention relates to the technical field of loudspeakers, and in particular to a speaker shell fixing and sealing structure and a speaker shell. Background Art

[0002] A speaker is usually composed of a speaker shell, speakers, a crossover and other components. The speakers and the crossover are both arranged inside the speaker shell. The speakers and the crossover require external power cords or audio cables and other wires, which are passed through the speaker shell.

[0003] To maintain the stability of the wire connection with the speaker and crossover, and to seal the wire holes on the speaker housing to ensure the speaker's sound quality, the wires usually need to be fixed to the speaker housing. Currently, the conventional fixing method is to directly inject glue into the flat end surface of the speaker housing where the wires are led out, or to create a glue storage groove on the side of the speaker housing where the wires are led out. Due to the structure of the speaker housing, the glue storage groove is usually shallow. Glue is injected into the glue storage groove to fix the wires to the speaker housing and seal the wires and the speaker housing.

[0004] However, the design of the above-mentioned fixing structure has the following defects: First, due to insufficient space for the colloid, the sealing and fixing effect of the glue is poor, and the colloid is easily separated 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, because 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, and the twisting wires will generate torque on the colloid, accelerating the process of the colloid separating and falling off relative to the speaker shell. Summary of the Invention

[0005] The technical problem to be solved by the present invention 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] In order to solve the above technical problems, in the first aspect, the speaker shell fixing and sealing structure provided by the present invention adopts the following technical solutions: A speaker shell fixed sealing structure includes a lead side panel arranged on the speaker shell, the lead side panel is used to pass the lead-out wires, a glue storage box is provided on the inner side of the lead side panel, the wires are also passed through the glue storage box, one side wall of the glue storage box is open and the opening direction is perpendicular to the lead-out direction of the wires, a glue injection hole is provided on the plate surface of the speaker shell near the opening of the glue storage box, and the axial projection of the contour edge of the glue injection hole opening is located inside the glue storage box.

[0007] By adopting the above technical solution, glue is injected into the glue injection hole, and the glue flows from the glue injection hole into the glue storage box, filling the glue storage box with glue, and the fluidity of the glue seals the wire insertion opening on the lead side panel to ensure the sealing of the speaker; and the colloid in the glue storage box can fix the wire to prevent the outer part of the wire from twisting during use, which affects the connection stability between the wire and the internal device. Through the setting of the glue storage box and the glue injection hole, the colloid is located inside the speaker shell, which significantly reduces the risk of the colloid separating and falling off relative to the speaker shell due to the twisting of the wire, thereby improving the quality of use of the speaker. In addition, since the glue is injected from top to bottom through the glue injection hole, the glue injection and sealing operation can be automated, thereby improving the glue injection efficiency.

[0008] Optionally, the cross-sectional profile of the inner wall of the glue injection hole is trapezoidal, and the small end of the glue injection hole faces the glue storage box.

[0009] By adopting the above technical solution, the flow direction and flow area of ​​the glue are guided and restricted through the trapezoidal glue injection hole, so that the glue flows into the center of the glue storage box and then disperses, thereby avoiding the glue flowing through the edge of the glue injection hole to other parts and then falling, causing the glue to fall outside the glue storage box or the edge of the opening. While achieving a larger glue injection surface, the accuracy of glue injection is guaranteed, and the glue injection efficiency is further improved.

[0010] Optionally, a boss is provided at the bottom of the glue storage box.

[0011] By adopting the above technical solution, the boss can support and limit the colloid in the glue storage box, thereby enhancing the strength of the colloid and better resisting the torque generated by the twisting of the wire on the colloid, thereby reducing the risk of the colloid separating from the inner wall of the glue storage box.

[0012] In a second aspect, the speaker housing provided by the present invention adopts the following technical solutions: A speaker shell comprises the above-mentioned speaker shell glue storage structure, a speaker upper shell and a speaker lower shell covered and installed on the speaker upper shell, the lead side panel is a side panel of the speaker upper shell through which the lead wires are passed, and the glue injection hole is opened in the speaker lower shell.

[0013] Optionally, the side walls of the glue storage box and the side panels of the lead wires are provided with placement openings, the inner wall contour of the placement openings is U-shaped and the U-shaped opening faces the lower shell of the speaker.

[0014] By adopting the above technical solution, the wires are first placed in the placement opening, and then the upper shell and the lower shell of the speaker are covered and welded, which improves the convenience of connecting and leading out the wires.

[0015] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The glue storage box and glue injection hole are designed to keep the glue inside the speaker housing, significantly reducing the risk of the glue separating from the speaker housing due to twisting of the wires, thereby improving the quality of the speaker. 2. Since 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; 3. The flow direction and flow area of ​​the glue are guided and restricted by the trapezoidal glue injection hole, thereby preventing the glue from flowing through the edge of the glue injection hole to other parts and then falling, causing the glue to fall outside the glue storage box or the edge of the opening. While achieving a larger glue injection surface, it ensures the accuracy of glue injection and further improves the glue injection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is combined with Figure 1-3 The present invention is described in further detail.

[0021] The embodiment of the present invention discloses a speaker shell, referring to Figure 1 The speaker shell includes an upper speaker shell 5, a lower speaker shell 6 and a speaker shell fixed sealing structure, and the lower speaker shell 6 covers and is welded to the upper speaker shell 5.

[0022] Reference Figure 1 and Figure 2 The speaker shell fixed sealing structure includes a lead side plate 1, which is a side plate of the speaker upper shell 5 for passing the lead wire 8. A glue storage box 2 is provided inside the lead side plate 1. The glue storage box 2 is a hollow rectangular body, and the wire 8 is passed through the two opposite side walls of the glue storage box 2 at the same time.

[0023] Reference Figure 1 、 Figure 2 and Figure 3The side wall of the glue storage box 2 facing the lower shell 6 of the speaker is open, and the opening direction 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 is provided with a glue injection hole 3, and the axial projection of the outline edge of the opening of the glue injection hole 3 is located inside the glue storage box 2.

[0024] Glue is applied to the glue injection hole 3, and the glue flows into the glue storage box 2 from the glue injection hole 3, filling the glue storage box 2 with glue, and the flowability of the glue seals the opening for the wire 8 on the lead side panel 1 to ensure the sealing of the speaker; and the colloid in the glue storage box 2 can fix the wire 8 to prevent the outer part of the wire 8 from twisting during use, which affects the connection stability between the wire 8 and the internal components. Through the arrangement of the glue storage box 2 and the glue injection hole 3, the colloid is located inside the speaker shell, which significantly reduces the risk of the colloid separating and falling off relative to the speaker shell due to the twisting of the wire 8, thereby improving the quality of use of the speaker. In addition, since the glue is injected from top to bottom through the glue injection hole 3, the glue injection and sealing operation can be automated, thereby improving the glue injection efficiency.

[0025] Reference Figure 3 The cross-sectional profile of the inner wall of the glue injection hole 3 is trapezoidal, with the small end of the glue injection hole 3 facing the glue storage box 2. The trapezoidal glue injection hole 3 guides and restricts the flow direction and flow area of ​​the glue, so that the glue flows into the center of the glue storage box 2 and then disperses, thereby preventing the glue from flowing through the edge of the glue injection hole 3 to other parts and then falling, causing the glue to fall outside the glue storage box 2 or the edge of the opening. This ensures a larger glue injection surface while ensuring the accuracy of glue injection, further improving the glue injection efficiency.

[0026] Reference Figure 2 The bottom of the glue storage box 2 is provided with a boss 4, which is located below the wire 8 and extends along the axis of the wire 8. The boss 4 can support and limit the colloid in the glue storage box 2, thereby strengthening the strength of the colloid and better resisting the torque generated by the twisting of the wire 8 on the colloid, thereby reducing the risk of the colloid separating from the inner wall of the glue storage box 2.

[0027] Reference Figure 2 The side wall of the glue storage box 2 and the lead side plate 1 are both provided with a placement opening 7. The inner wall contour of the placement opening 7 is U-shaped and the U-shaped opening faces the lower shell 6 of the speaker. First, the wire 8 is placed in the placement opening 7, and then the upper shell 5 and the lower shell of the speaker are covered and welded, which improves the processing convenience of connecting and leading out the wire 8.

[0028] The implementation principle of a speaker shell fixing and sealing structure and a speaker shell according to an embodiment of the present invention is as follows: glue is injected into the glue injection hole 3, and the glue flows from the glue injection hole 3 into the glue storage box 2, and the glue storage box 2 is filled with glue. The fluidity of the glue seals the opening for the wire 8 on the lead side panel 1 to ensure the sealing of the speaker; and the colloid in the glue storage box 2 can fix the wire 8 to avoid the outer part of the wire 8 from twisting during use, which affects the connection stability between the wire 8 and the internal device. By setting the glue storage box 2 and the glue injection hole 3, the colloid is located inside the speaker shell, which significantly reduces the risk of the colloid separating and falling off relative to the speaker shell due to the twisting of the wire 8, thereby improving the quality of use of the speaker.

[0029] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
