Description

Technical Field

[0001] The utility model relates to the technical field of sound boxes, in particular to a speaker top cover installation structure. Background Art

[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it refers to a speaker box or a subwoofer box with a built-in power amplifier, which amplifies the audio signal and then plays it back by the speaker itself, making the sound louder. The speaker is the main component of the sound system.

[0003] Traditional aluminum tube speakers such as Figure 4 and Figure 5 As shown, the fixing method of the shell and the top cover is:

[0004] 1. Use adhesive tape to temporarily fix the top cover to the aluminum tube shell;

[0005] 2. Pour glue into the speaker hole;

[0006] 3. After the glue is cured, tear off the adhesive tape to complete the bonding;

[0007] The disadvantages of this fixing method are that it is difficult to apply glue, it is difficult for the glue to spread all around the bonding points in the pipe, and there is a risk of air leakage or vibration. At the same time, the glue may flow out of the surface and cause poor appearance. Utility Model Content

[0008] The utility model aims to solve the shortcomings of the prior art that it is difficult to apply glue, it is difficult for glue to spread all around the bonding points in the tube, and there may be risks of air leakage or vibration, and proposes a speaker top cover installation structure.

[0012] A speaker mounting hole is provided in the aluminum tube housing for mounting a speaker;

[0013] A blocking cloth, wherein a receiving groove is provided in the top cover, and the blocking cloth is arranged in the receiving groove to shield dust from the installed speaker, and a set of reset components is arranged in the receiving groove, and the reset components are arranged in the receiving groove to store the blocking cloth in the receiving groove;

[0014] A positioning component is used to position the cloth when the cloth is used to protect the loudspeaker.

[0015] In a possible design, the reset assembly includes a fixed rod fixed in a receiving groove, a clockwork spring is sleeved on the surface of the fixed rod, a rotating cylinder rotates in the receiving groove, the baffle cloth is wrapped and fixed on the surface of the rotating cylinder, one end of the clockwork spring is fixed to the surface of the fixed rod, the other end of the clockwork spring is fixed to the inner wall of the rotating cylinder, and a connecting rod is fixed to the side end of the baffle cloth.

[0016] In a possible design, the positioning assembly includes a fixed card plate fixed to the top of the top cover, and a fixed card slot matching and engaging with the fixed card plate is formed in the connecting rod.

[0017] In a possible design, both ends of the connecting rod protrude outward.

[0018] In a possible design, a non-slip pad is provided at the bottom end of the base plate.

[0019] In a possible design, both of the top covers are made of MDF material.

[0020] In a possible design, the two top covers may also be made of HDF, ABS, plastic or metal materials.

[0021] In the present application, when the speaker needs to be protected, the connecting rod is pulled outward through the extending parts at both ends of the connecting rod, and the connecting rod drives the baffle cloth to extend outward, and the connecting rod is pulled upward and the fixed slot in the connecting rod is aligned with the fixed card plate to clamp the connecting rod, fix the connecting rod and the connecting rod to the position of the baffle cloth, and the elasticity of the clockwork spring straightens the baffle cloth so that the baffle cloth can effectively protect the speaker. When the speaker needs to be used, the connecting rod can be removed from the fixed card plate, and the reset property of the clockwork spring can be used to pull the baffle cloth and the connecting rod to reset, thereby exposing the speaker.

[0022] Beneficial Effects

[0023] In the utility model, in the technical scheme, an inner partition is added to the top of the aluminum tube shell, and the edge of the inner partition has a uniform inclined glue groove, and the fixing steps are: the inner partition is clamped on the top of the inside of the aluminum tube shell and is flush with the top of the aluminum tube; glue is added to the glue groove at the edge of the inner partition to allow the inner partition and the aluminum tube shell to be fully bonded and completely sealed; glue is evenly applied to the top surface of the inner partition, and then the top cover is placed and temporarily fixed with adhesive tape, and the adhesive tape is torn off after the glue is cured. When installing the bottom plate, the aluminum tube shell is inverted and the above steps are repeated. Since the glue is applied in a circle around the bonding front, the operation is simple and the bonding seal is reliable, which completely solves the problem of air leakage or vibration and increases the structural strength of the speaker. Since there is a glue groove around the partition, the glue will not overflow from the surface. BRIEF DESCRIPTION OF THE DRAWINGS
