DETAILED DESCRIPTION

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. 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 1-5 A long strip-type combined surround ceiling speaker includes a rectangular mounting base 1 and two ceiling speaker bodies 2. The rectangular mounting base 1 is provided with a rectangular annular protrusion 3 on the side wall facing the ceiling speaker body 2. The right side of the two ceiling speaker bodies 2 is provided with the same rectangular fixing base 4, which is inserted into the rectangular annular protrusion 3. An adhesive layer 8 is filled between the side wall of the rectangular fixing base 4 and the inner wall of the rectangular annular protrusion 3. The material of the adhesive layer 8 is water-based polyurethane adhesive. The rectangular fixing base 4 is inserted into the rectangular annular protrusion 3 and fixed with the adhesive layer 8 to improve the sealing effect of the connection.

[0023] Two circular through slots 5 are provided on the rectangular fixing seat 4, and the two ceiling speaker bodies 2 are respectively arranged opposite the two circular through slots 5. Two symmetrically distributed positioning blocks 6 are fixedly connected to the side walls of the two ceiling speaker bodies 2 opposite the rectangular fixing seat 4. Four positioning slots 7 are provided on the side walls of the rectangular fixing seat 4 opposite the ceiling speaker body 2. The four positioning blocks 6 are respectively inserted into the four positioning slots 7 and snap-fitted for positioning. The four positioning slots 7 are respectively provided with rectangular protrusions 9 on the inner walls of the positioning blocks 6. The four positioning blocks 6 are respectively provided with rectangular card slots 10 on the side walls opposite the positioning slots 7. The rectangular protrusions 9 are inserted into the rectangular card slots 10. Circular grooves 11 are provided on the opposite side walls of the two positioning blocks 6 on the same side. Springs 12 are fixedly connected to the opposite inner walls of the two circular grooves 11, and the two springs 12 are away from the inner walls of the circular grooves 11 One end of each is fixedly connected to a circular limit block 13, and the two circular limit blocks 13 are provided with a cylindrical protrusion 14 on the end away from the spring 12. The two rectangular slots 10 are provided with a cylindrical slot 15 on the inner wall of the circular slot 11. The two cylindrical protrusions 14 are respectively inserted into the two cylindrical slots 15. Pressing the cylindrical protrusion 14 on the positioning block 6 drives the circular limit block 13 to move along the circular slot 11 and compress the spring 12 until the four positioning blocks 6 on the two ceiling speaker bodies 2 can be respectively inserted into the four positioning slots 7 on the rectangular fixing seat 4. At this time, the compressed spring 12 elastically resets and drives the cylindrical protrusion 14 on the circular limit block 13 to be inserted into the cylindrical slot 15, so that the spring 12 in the circular slot 11 cooperates with the circular limit block 13 to press the cylindrical protrusion 14 tightly and position it in the cylindrical slot 15.

[0024] The cylindrical protrusion 14 is integrally formed with the circular limit block 13, the rectangular protrusion 9 is integrally formed with the rectangular fixing seat 4, and the rectangular annular protrusion 3 is integrally formed with the rectangular mounting seat 1. According to claim 4, a long strip-type combined surround ceiling speaker is characterized in that a plurality of cylindrical slots 15 are provided with strip openings 16 on the inner wall facing the ceiling speaker body 2, and the strip openings 16 are connected with the positioning slots 7. The four cylindrical protrusions 14 are provided with rectangular slots 17 on the annular side walls facing the strip openings 16. When disassembling, it is only necessary to pull the cylindrical protrusion 14 and the cylindrical slot 15 apart through the strip opening 16 and the rectangular slot 17, and pull the ceiling speaker body 2 to separate the positioning block 6 from the positioning slot 7, which is convenient for disassembly and maintenance.

[0025] When the utility model is in use, the cylindrical protrusion 14 on the pressing positioning block 6 drives the circular limiting block 13 to move along the circular groove 11 and compress the spring 12 until the four positioning blocks 6 on the two ceiling speaker bodies 2 can be respectively inserted into the four positioning slots 7 on the rectangular fixing seat 4. At this time, the compressed spring 12 elastically resets and drives the cylindrical protrusion 14 on the circular limiting block 13 to be inserted into the cylindrical card groove 15, so that the spring 12 in the circular groove 11 cooperates with the circular limiting block 13 to press the cylindrical protrusion 14 into the cylindrical card groove 15, and the rectangular protrusion 9 on the positioning slot 7 is inserted. In the rectangular slot 10 on the positioning block 6, the two ceiling speaker bodies 2 are effectively clipped and fixed on the rectangular fixing seat 4. When disassembling, it is only necessary to pull the cylindrical protrusion 14 and the cylindrical slot 15 apart through the strip opening 16 and the rectangular slot 17, and pull the ceiling speaker body 2 to separate the positioning block 6 from the positioning slot 7, which is convenient for disassembly and maintenance. Then, the rectangular fixing seat 4 is inserted into the rectangular annular protrusion 3 and fixed with the adhesive layer 8 to improve the sealing effect of the connection, and the rectangular fixing seat 4 is tightly attached to the side wall of the rectangular mounting seat 1, which is convenient for the combined use of the ceiling speaker body 2 and improves the sound quality.
