Then, fix the connecting ring 24 in the installation groove 111 through the assembly bolt 241 to realize the combined fixation of the broadcasting casing 2 on both sides of the main body casing 11.
[0034] Refer to Figure 2 , through holes are formed on the surface of the broadcasting casing 2, and the through holes include a first broadcasting port 211 and a second broadcasting port 212. The first broadcasting port 211 is partially opened on the side wall of the broadcasting casing 2, and the second broadcasting port 212 is opened at the end of the broadcasting casing 2. Speakers can be assembled at the first broadcasting port 211 and the second broadcasting port 212 respectively. When the customer uses it, the customer can directly play through the speaker at the first broadcasting port 211, or can perform dual-channel playback through the speaker at the second broadcasting port 212. The customer can choose multiple modes for audio playback to improve the auditory effect.
[0035] Refer to Figure 3 And Figure 4 , a dust-proof cloth 3 is arranged on the broadcasting casing 2. The dust-proof cloth 3 is adapted to the shape of the broadcasting casing 2 and is sleeved on the outer surface of the broadcasting casing 2. Six fastening grooves 22 are symmetrically opened on the outer side wall of the broadcasting casing 2. Hook buckles 221 are fixedly arranged on the bottom walls of all the fastening grooves 22, and the tops of the hook buckles 221 are bent away from the dust-proof cloth 3. Six convex edges 31 are integrally formed at the end of the dust-proof cloth 3, and hook holes 311 are opened on the convex edges 31. The hook holes 311 are sleeved on the hook buckles 221.
[0036] Refer to Figure 3 And Figure 4 , when the customer installs the dust-proof cloth 3, the dust-proof cloth 3 is sleeved on the broadcasting casing 2, and the hook holes 311 are sleeved on the hook buckles 221 and pressed to the bottom of the fastening grooves 22. All the convex edges 31 together tighten and fix the dust-proof cloth 3 on the broadcasting casing 2. The dust-proof cloth 3 simultaneously covers the first broadcasting port 211 and the second broadcasting port 212 on the broadcasting casing 2 to prevent dust from entering the inside of the casing through the broadcasting port. When the customer removes the dust-proof cloth 3 for cleaning or replacement, the hook holes 311 are removed from the hook buckles 221, and the dust-proof cloth 3 can be detached from the broadcasting casing 2. Without using other tools, the customer can remove or install the dust-proof cloth 3 for cleaning or replacement.
[0037] In order to prevent the flange 31 from loosening and detaching from the hook 221 as much as possible, refer to Figure 3 and Figure 4 A clamping cover 23 is hingedly provided on the side wall of the fastening groove 22. The inner wall of the clamping cover 23 can abut against the convex edge 31. The outer surface of the clamping cover 23 is flush with the outer surface of the broadcasting shell 2.

A friction pattern 2321 is provided on the outer surface of the shifting block 232, which helps to increase the friction force when the shifting block 232 is shifted. The shifting block 232 is fixedly connected to the locking tongue 231. A locking groove 222 is opened and closed on the side wall of the fastening groove 22. The locking tongue 231 can be inserted into the locking groove 222 and abut against the locking groove 222. The clamping cover 23 is rotated, and the clamping cover 23 further presses the convex edge 31 into the fastening groove 22. Next, the shifting block 232 is shifted, and the shifting block 232 drives the locking tongue 231 to be inserted into the locking groove 222, and the pressing cover 23 is locked in the fastening groove 22. In this way, the convex edge 31 is prevented from loosening and disengaging from the hook 221 as much as possible.
[0038] In order to improve the appearance of the shell, refer to Figures 1 to 3 The outer surface of the dustproof cloth 3 is covered with a shielding shell 4, and a through hole 41 is opened on the shielding shell 4. The through hole 41 and the first broadcasting hole 211 are arranged at two locations corresponding to the first broadcasting hole 211.

The shielding shell 4 shields the fastening groove 22 inside, which improves the flatness and aesthetics of the outer shell. A rubber layer 25 is coated and fixed on the surface of the end of the broadcasting shell 2, and the inner wall of the end of the shielding shell 4 presses the dustproof cloth 3 against the rubber layer 25. The rubber layer 25 increases the friction between the shielding shell 4 and the dustproof cloth 3, and tries to avoid the dustproof cloth 3 from sliding on the surface of the shielding shell 4.
[0039] The implementation principle of a high-quality sound injection molded housing in the embodiment of the present application is as follows: when the customer installs the dustproof cloth 3, first put the dustproof cloth 3 on the outside of the broadcast shell 2. Then pull the convex edge 31 into the corresponding fastening groove 22, so that the hook hole 311 is sleeved on the hook buckle 221 and pressed to the bottom of the fastening groove 22. At this time, all the convex edges 31 together tighten and fix the dustproof cloth 3 on the outer surface of the broadcast shell 2, and completely cover the broadcast port on the broadcast shell 2. Then cover the pressing cover 23 and lock the pressing cover 23 in the fastening groove 22. Finally, put on the shielding shell 4 to ensure that the through opening 41 of the side wall of the shielding shell 4 is aligned with the first broadcast port 211, so that the shielding shell 4 is clamped and fixed on the broadcasting shell 2. The shielding shell 4 shields the fastening groove 22 inside, which improves the flatness and aesthetics of the shell appearance.
[0040] When the customer needs to remove the dust-proof cloth 3 for cleaning or replacement, pull out the shielding shell 4 and open the pressing cover 23, remove the hook hole 311 from the hook 221, the convex edge 31 can be disengaged from the fastening groove 22, and the dust-proof cloth 3 can be removed from the outer surface of the sound box shell 2. In this way, without using any tools, the customer can remove or install the dust-proof cloth 3 for cleaning or replacement, minimizing the adhesion of a large amount of dust on the dust-proof cloth 3 and ensuring the sound quality of the speaker.
[0041] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
