[0023] like Figure 1 and Figure 2 As shown, the acoustic sealing structure described in the utility model includes an acoustic body 1, on the top surface of which a control button 11 is arranged. To achieve the purpose of the invention of the utility model, the structure also includes a transparent soft rubber cover 2, which can be detachably mounted on the upper end of the acoustic body 1, and the control button 11 is covered in the soft rubber cover 2.

[0024] In the sealing structure of the speaker, a transparent soft rubber cover 2 is used to cover the upper end of the speaker body 1, and the control button 11 is covered in the soft rubber cover 2. The soft rubber cover 2 is not only convenient for covering, but also convenient for the user to observe and operate the control button 11 through the soft rubber cover 2, and the soft rubber cover 2 can provide a very good shielding and protection for the control button 11, thereby preventing dust and water from entering the gap between the control button 11 and the speaker housing, which is not only convenient for cleaning and maintenance, but also reduces the aging speed of the control button 11, and can greatly reduce the probability of damage to the internal electrical components of the speaker, thereby helping to extend the service life of the speaker.

[0025] By detachably mounting the soft rubber cover 2 on the upper end of the audio body 1 , the soft rubber cover 2 can be easily removed for cleaning and maintenance separately, which helps to improve the convenience of cleaning and maintenance of the soft rubber cover 2 .

[0026] like Figure 1 As shown, the sound outlet 10 of the speaker body 1 is located on its lower end, and the soft rubber cover 2 is not covered on the sound outlet 10. This can prevent the soft rubber cover 2 from affecting the sound of the speaker, so that the sound sealing structure can still meet normal use requirements.

[0027] like Figures 1 to 6 , Figure 8 As shown, a convex ring portion 21 is provided on the outer edge of the cover opening of the soft rubber cover 2. The convex ring portion 21 can not only enhance the structural strength of the soft rubber cover 2, but also be grasped by fingers, so that it is convenient for users to put on and remove the soft rubber cover 2, thereby helping to improve the convenience of installing and removing the soft rubber cover 2. When water falls on the soft rubber cover 2, the convex ring portion 21 can play a certain shielding role to reduce the probability of water flowing on the sound body 1, thereby further reducing the impact of water on the sound.

[0028] like Figure 6 and Figure 8As shown, the convex ring portion 21 is a conical convex portion that bulges obliquely downward, and the convex ring portion 21 is gradually away from the speaker body 1. This not only makes it easier to hold with fingers, but also plays a better role in blocking and guiding water, thereby helping to further improve the convenience of installing and removing the soft rubber cover 2, and can further reduce the impact of water on the speaker.

[0029] like Figure 6 and Figure 8 As shown, the convex ring portion 21 and the soft rubber cover 2 are an integrally formed soft TPU plastic structure or a soft silicone structure or a soft silicone rubber structure. This allows the soft rubber cover 2 to have a very soft characteristic, which not only facilitates the operation of the control button 11, but also makes the contact very comfortable, and facilitates the assembly and disassembly of the soft rubber cover 2, and ensures that the soft rubber cover 2 is more stable, which helps to further improve the reliability and applicability of the acoustic sealing structure.

[0030] like Figure 3 and Figure 4 As shown, at least one air guide groove 23 is provided on the cavity wall of the inner cavity 22 of the soft rubber cover 2, and the two ends of the air guide groove 23 extend to the cavity bottom of the inner cavity 22 and the edge of the cover opening of the soft rubber cover 2, respectively. When the soft rubber cover 2 is installed, the air inside can be quickly discharged through the air guide groove 23, thereby helping to further improve the convenience of installing the soft rubber cover 2. When the soft rubber cover 2 is removed, the air can quickly enter the soft rubber cover 2 through the air guide groove 23, which can avoid excessive negative pressure in the soft rubber cover 2 and affect the removal, thereby further improving the convenience of removing the soft rubber cover 2.

[0031] like Figure 1 and Figure 2 As shown, at least one sound pickup hole 12 is provided on the speaker body 1, and the sound pickup hole 12 is covered in a soft rubber cover 2. When a microphone is provided in the speaker body 1, the sound pickup hole 12 allows sound to pass through the sound pickup hole 12 and act on the microphone. The sound pickup hole 12 is covered in the soft rubber cover 2, which can provide a good shielding effect on the sound pickup hole 12, thereby preventing dust and water from entering the speaker body 1 through the sound pickup hole 12, and further helping to further improve the reliability and service life of the speaker sealing structure. Although the soft rubber cover 2 has a certain influence on the sound pickup of the microphone, since the sound pickup hole 12 is provided on the speaker body 1, this influence is not great, and it can still meet people's normal use.

[0032] like Figures 1 to 3 As shown, the outer opening of the sound pickup hole 12 is connected to the air guide groove 23. In this way, the sound can penetrate into the sound pickup hole 12 through the air guide groove 23, which can reduce the amount of sound attenuation, thereby better meeting the actual use requirements.

[0033] like Figures 5 to 7As shown, the sound pickup hole 12 is located on the top surface of the sound body 1, and a convex tube portion 24 connected to the sound pickup hole 12 is provided on the top surface of the soft rubber cover 2, and a cover cap 25 is provided on the outer cover of the convex tube portion 24, and a first sound passing gap 26 is reserved between the cover cap 25 and the outer wall of the soft rubber cover 2, and a second sound passing gap 27 connected to the first sound passing gap 26 and the inner hole 241 of the convex tube portion 24 is reserved between the cover cap 25 and the convex tube portion 24. This can improve the sound pickup performance of the sound pickup hole 12 while preventing dust and rain from directly entering the sound pickup hole 12, which helps to further improve the reliability and applicability of the sound sealing structure.

[0034] The utility model provides two kinds of soft rubber covers 2, which are: the first kind is a soft rubber cover 2 without a convex tube portion 24 and a covering cap 25, such as Figures 1 to 4 The second type is a soft rubber cover 2 with a convex tube portion 24 and a covering cap 25, such as Figures 5 to 8 shown.

[0035] like Figure 6 and Figure 7 As shown, a plurality of convex pillars 28 are arranged on the top surface of the soft rubber cover 2, and each convex pillar 28 is arranged around the convex tube 24. The height of the convex pillar 28 is lower than that of the convex tube 24, and the bottom of the cover cap 25 is connected to the top of each convex pillar 28. This can help improve the stability of the installation and positioning of the cover cap 25, so that the cover cap 25 can have a better covering and protective effect.

[0036] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
