Description

Technical Field

[0001] The utility model relates to the technical field of speaker sealing, and specifically relates to a speaker sealing structure. Background Technique

[0002] A speaker is a transducer that converts an electrical signal into a sound signal. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but for the audio effect, it is the most important component. There are many types of speakers, and the prices vary greatly. The audio electrical energy makes its paper cone or diaphragm vibrate through electromagnetic, piezoelectric or electrostatic effects and resonate (sympathize) with the surrounding air to emit sound. The speaker is a unit for converting electricity into sound. For the actual product to meet the relevant requirements for the optimal conversion of electricity into sound, the existing speaker needs absolute isolation and sealing inside to better restore the original sound. If there is a little leakage, it will affect the sound;

[0003] The existing method for sealing the speaker is to use a large amount of glue to seal it during the assembly process. However, the assembly process takes too long, and the glue is easy to remain in other irrelevant places and components. At the same time, the vibration generated by the speaker during operation may cause the displacement of the sealing rubber ring, resulting in a decrease in the sealing effect; Therefore, we need to propose a speaker sealing structure.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] The present invention provides: a speaker sealing structure, as Figures 1-4 shown, including a speaker housing 1 and a mounting plate 2. The mounting plate 2 is sealingly arranged on the upper surface of the speaker housing 1. A basket 10 is fixedly arranged inside the mounting plate 2. A paper cone 4 is arranged inside the basket 10 on the inner side of the mounting plate 2. A sealing rubber ring 3 is clamped between the mounting plate 2 and the paper cone 4, and a sealing groove 14 corresponding to the sealing rubber ring 3 is opened on the side surface of the mounting plate 2;

[0023] A plurality of groups of limiting components 5 for pressing and limiting the sealing rubber ring 3 are arranged on the upper surface of the mounting plate 2; the sealing rubber ring 3 is clamped inside the sealing groove 14, and then the tightening plate 13 is operated to move downward, and is fixed by the spring plunger 17 being inserted into the positioning hole 19, so that the upper surface of the sealing rubber ring 3 is tightened by the tightening plate 13, and then the sealing rubber ring 3 is fixed, avoiding the overflow of glue and at the same time avoiding the displacement of the sealing rubber ring 3 driven by the vibration of the speaker during operation.

[0024] Preferably, the limiting component 5 includes a fixed plate 11, a connecting plate 12, a tightening plate 13 and a clamping module. The fixed plate 11 is fixedly installed on the upper surface of the mounting plate 2. The connecting plate 12 is slidably arranged on the side of the fixed plate 11 close to the sealing rubber ring 3. The tightening plate 13 is fixedly installed on the side of the connecting plate 12 away from the fixed plate 11. The fixed plate 11 is fixedly connected to the mounting plate 2, and then the tightening plate 13 is driven to move on the side surface of the fixed plate 11 through the connecting plate 12. After the paper cone 4 is installed inside the mounting plate 2, the sealing rubber ring 3 is clamped inside the sealing groove 14. At this time, the protruding section of the sealing rubber ring 3 blocks the connection between the mounting plate 2 and the paper cone 4, and then the sealing rubber ring 3 is tightened by the tightening plate 13, so as to further ensure the sealing between the mounting plate 2 and the paper cone 4 and at the same time avoid dust from entering the basket 10.

[0025] Furthermore, the snap-fitting module includes extension rods 15, snap blocks 16, and spring plungers 17. There are two sets of both the extension rods 15 and the snap blocks 16. The two sets of extension rods 15 are fixedly installed on the side of the pressing plate 13 away from the sealing rubber ring 3. The two sets of snap blocks 16 are fixedly installed on the side of the extension rods 15 away from the sealing rubber ring 3. The spring plungers 17 are fixedly installed on the side of the pressing plate 13 away from the sealing rubber ring 3. By providing the extension rods 15, the snap blocks 16 are fixedly connected to the connecting plate 12, thereby ensuring that when the connecting plate 12 and the pressing plate 13 move, the snap blocks 16 and the spring plungers 17 move synchronously.

[0026] Furthermore, the extension rods 15 are each provided as convex blocks, and a snap groove 18 corresponding to the extension rods 15 is formed on the side of the fixing plate 11 close to the sealing rubber ring 3. The formation of the snap groove 18 enables the snap blocks 16 to move along the snap groove 18, and the extension rods 15 being provided as convex blocks ensures that the snap blocks 16 can only move in a straight line up and down along the snap groove 18, thereby ensuring that the pressing plate 13 moves in a straight line.

[0027] It should be noted that the spring plungers 17 are arranged between the two sets of extension rods 15, and a positioning hole 19 corresponding to the spring plungers 17 is formed on the side of the fixing plate 11 close to the sealing rubber ring 3. When the pressing plate 13 presses the sealing rubber ring 3 tightly, the spring plungers 17 are snapped into the positioning holes 19, thereby enhancing the stability of the pressing plate 13 in tightly pressing the sealing rubber ring 3.

[0028] Specifically, the sealing rubber ring 3 is arranged inside the sealing groove 14, and the lower surface of the pressing plate 13 is in contact with the upper surface of the sealing rubber ring 3. The sealing rubber ring 3 being snapped into the sealing groove 14 prevents the sealing rubber ring 3 from moving in the left-right direction, and the protruding sealing rubber ring 3 is provided with an extended section and contacts the paper cone 4 through the extended end, thereby sealing the connection between the mounting plate 2 and the paper cone 4.

[0029] In addition, a spider 6, a voice coil 7, a magnet 8, and a pole piece 9 are sequentially arranged below the mounting plate 2. The provision of the spider 6, the voice coil 7, the magnet 8, and the pole piece 9 ensures the normal operation of the speaker.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
