Therefore, they cannot be understood as limitations on the present invention.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4, a combined surround ceiling speaker that is easy to disassemble and replace, including a ceiling speaker body 1 and a ceiling 2. The ceiling speaker body 1 is a long strip design. Multiple long strip ceiling speaker bodies 1 are combined to form a surround sound environment with a stronger sense of stereo. It has rich usage scenarios and can be used as background music with a stronger sense of stereo. The upper end of the center position of the ceiling speaker body 1 is fixedly connected with a mounting base 3. Two L-shaped mounting blocks 4 are placed on the ceiling 2. Two expansion screws 5 are penetrated on the horizontal sections of the two L-shaped mounting blocks 4. Several expansion screws 5 are fixedly connected to the ceiling 2. The two L-shaped mounting blocks 4 are set close to the ceiling 2. The two expansion screws 5 penetrate the horizontal sections of the L-shaped mounting blocks 4 and then screwed into the ceiling 2 for fixation. The two L-shaped mounting blocks 4 are fixed on the opposite side walls. It is connected to a buffer pad 6, which is provided with a circular wire groove 7. The mounting base 3 is inserted between the two L-shaped mounting blocks 4 and contacts the buffer pad 6. The upper end of the mounting base 3 near the outer wall is fixedly connected with four columnar plug blocks 8, and the lower end of the buffer pad 6 is provided with four columnar slots 9. The four columnar plug blocks 8 are respectively inserted into the four columnar slots 9. The columnar plug blocks 8 and the mounting base 3 are integrated into a molded arrangement. The four columnar plug blocks 8 and the four columnar slots 9 are all cross-distributed. The mounting base 3 at the upper end of the ceiling speaker body 1 is inserted between the two L-shaped mounting blocks 4, so that the four cross-distributed columnar plug blocks 8 at the upper end of the mounting base 3 are respectively inserted into several columnar slots 9 at the lower end of the buffer pad 6, effectively limiting the mounting base 3 between the two L-shaped mounting blocks 4.

[0023] The mounting base 3 is provided with positioning components on the left and right side walls close to the ceiling speaker body 1, and the positioning components are clamped with the vertical side walls of the two L-shaped mounting blocks 4. The positioning components include circular grooves 10 provided on the left and right side walls of the mounting base 3. The two circular grooves 10 are provided close to the upper end of the ceiling speaker body 1. Springs 11 are fixedly connected to the opposite inner walls of the two circular grooves 10. The ends of the two springs 11 away from the inner walls of the circular grooves 10 are fixedly connected to columnar positioning blocks 12. Circular positioning holes 13 are provided on the opposite side walls of the vertical sections of the two L-shaped mounting blocks 4. The mounting base 3 at the upper end of the ceiling speaker body 1 is inserted between the two L-shaped mounting blocks 4, so that the columnar positioning blocks 12 at the left and right ends of the mounting base 3 are in contact with the two L-shaped mounting blocks 4. At this time The arcuate end surface of the columnar positioning block 12 is subjected to force against the side wall of the L-shaped mounting block 4, so that the columnar positioning block 12 shrinks into the circular groove 10 and compresses the spring 11. When the columnar positioning block 12 moves along the L-shaped mounting block 4 to face the circular positioning hole 13, the compressed spring 11 drives the columnar positioning block 12 to pass through the circular positioning hole 13, effectively clamping and positioning the ceiling speaker body 1 and the mounting base 3 between the two L-shaped mounting blocks 4. It has a small size and is easy to install, disassemble and maintain. It can be used in combination according to the needs of different spaces, and has good overall consistency. The two columnar positioning blocks 12 are both provided with arcuate end surfaces at one end of the circular groove 10, and the two columnar positioning blocks 12 are respectively passed through the two circular positioning holes 13. The buffer pad 6 and the columnar positioning block 12 are both made of rubber.

[0024] When the present invention is in use, the two L-shaped mounting blocks 4 are set close to the ceiling 2, and the two expansion screws 5 are screwed into the ceiling 2 after passing through the horizontal section of the L-shaped mounting block 4 to fix it. The mounting base 3 on the upper end of the ceiling speaker body 1 is inserted between the two L-shaped mounting blocks 4, so that the columnar positioning blocks 12 at the left and right ends of the mounting base 3 are in contact with the two L-shaped mounting blocks 4. At this time, the arc-shaped end surface of the columnar positioning block 12 is subjected to force against the side wall of the L-shaped mounting block 4, so that the columnar positioning block 12 is contracted into the circular groove 10 and the spring 11 is compressed until the four cross-shaped columnar plug-in blocks 8 on the upper end of the mounting base 3 are respectively inserted into the several columnar slots 9 at the lower end of the buffer pad 6. At this time, the mounting base 3 The cylindrical positioning block 12 is moved to face the circular positioning hole 13, and the compressed spring 11 drives the cylindrical positioning block 12 to pass through the circular positioning hole 13, effectively clamping and positioning the ceiling speaker body 1 and the mounting base 3 between the two L-shaped mounting blocks 4. When disassembling, you only need to press the cylindrical positioning block 12 to separate from the circular positioning hole 13, and pull the ceiling speaker body 1 to separate the cylindrical plug 8 from the cylindrical slot 9. It has a small size and is easy to install and disassemble and maintain. It can be used in combination according to the needs of different spaces. The overall consistency is good. Multiple long-strip ceiling speaker bodies 1 are combined to form a surround sound environment with a stronger sense of stereo. It has rich usage scenarios and can be used as background music with a stronger sense of stereo.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
