[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Please also read Figures 1 to 7 Now, the speaker quick self-locking structure 10 provided in the embodiment of the present application is described. The speaker quick self-locking structure 10 comprises: a main body shell 11, a sound cavity shell 12 and a speaker assembly 13.

[0036] The speaker assembly 13 is installed in the sound cavity shell 12, and the sound cavity shell 12 is installed in the main body shell 11; the main body shell 11 is provided with a first positioning column 111, and the top of the first positioning column 111 is provided with an elastic locking piece 112; the side of the sound cavity shell 12 is provided with a first positioning seat 121, and the first positioning seat 121 is provided with a first locking hole 122 running through its upper and lower surfaces; when the sound cavity shell 12 is installed in the main body shell 11, the elastic locking piece 112 is inserted into the first locking hole 122 from bottom to top.

[0037] Specifically, the sound cavity shell 12 is set up, and after the speaker is installed in the sound cavity shell 12, the sound cavity shell 12 is then installed in the main body shell 11; with such a structure, there is no need to change the first positioning columns 111 of the main body shell 11, and speakers of different specifications and sizes can be installed, thereby improving the installation versatility of the main body shell 11 to adapt to speakers of different specifications and sizes; at the same time, the first positioning column 111 is provided with an elastic locking piece 112, and the side of the sound cavity shell 12 is provided with a first locking hole 122 for the elastic locking piece 112 to lock and install. When assembling the sound cavity shell 12, the tedious operation of screw tightening can be avoided, thereby shortening the production cycle of the product and further improving the production efficiency of the product.

[0038] In some embodiments of the present application, there are at least three elastic locking members 112, and at least three elastic locking members 112 are arranged in a circular array with equal spacing on the top of the first positioning column 111 to form a circular convex hull structure. The elastic locking member 112 includes a main body 1121 and a supporting portion 1122, one end of the main body 1121 is integrally formed on the top of the first positioning column 111; the supporting portion 1122 is integrally formed on the other end of the main body 1121, and the supporting portion 1122 extends outward to form a first supporting plane 1123; when the elastic locking member 112 is inserted into the first locking hole 122, the supporting portion 1122 is exposed on the top of the first positioning seat 121, and the first supporting plane 1123 is against the upper surface of the first positioning seat 121 to lock the sound cavity shell 12.

[0039] Specifically, when assembling the sound cavity shell 12, first align the elastic locking piece 112 with the first locking hole 122; then move the sound cavity shell 12 downward so that the elastic locking piece 112 is inserted into the first locking hole 122; at this time, since the abutment 1122 abuts against the inner side surface of the first locking hole 122, when the sound cavity shell 12 continues to be moved downward, multiple abutment 1122 can be synchronously moved toward the center direction of the first locking hole 122; when the elastic locking piece 112 is fully inserted into the first locking hole 122, multiple abutment 1122 can be exposed at the top of the first positioning seat 121. At this time, since the force on the abutment 1122 is cancelled, the multiple abutment 1122 move away from each other to lock on the first positioning seat 121, thereby locking the sound cavity shell 12.

[0040] In more detail, the bottom of the first locking hole 122 is provided with a first guiding slope 1221, and the first guiding slope 1221 is inclined from bottom to top toward the center direction of the first locking hole 122; the top of the side of the abutting portion 1122 is provided with a second guiding slope 1124 adapted to the first guiding slope 1221, and when the elastic locking member 112 is inserted into the first locking hole 122, the second guiding slope 1124 and the first guiding slope 1221 abut against each other to cause the plurality of abutting portions 1122 to move toward the center direction. When the abutting portion 1122 is inserted from the bottom of the first locking hole 122 and moves upward to be exposed on the upper surface of the first positioning seat 121, the force acting on the abutting portion 1122 will be cancelled, and the elastic force of the main body 1121 will be used to cause the plurality of abutting portions to move away from each other, so that the first abutting plane 1123 can abut against the upper surface of the first positioning seat 121, thereby completing the locking of the sound cavity housing 12.

[0041] In other embodiments of the present application, the sound cavity housing 12 includes a base shell 1201 and a rear cover 1202 installed on the rear side of the base shell 1201. The base shell 1201 is provided with a first installation cavity 1203 that runs through its front and rear surfaces, and the speaker assembly 13 is fixedly installed in the first installation cavity 1203. The rear side surface of the base shell 1201 is provided with a first assembly groove 1204, and the front surface of the rear cover 1202 is provided with a first assembly ridge 1205, and the first assembly ridge 1205 can be inserted into the first assembly groove 1204; such a structure can improve the firmness of the assembly between the rear cover 1202 and the base shell 1201, and it is not easy to get loose.

[0042] Specifically, the sound cavity shell is provided with a plurality of screw holes, and the speaker assembly is fixedly installed by screwing the speaker assembly into the screw holes. Since the sound cavity shell is provided with a first installation cavity, a plurality of speaker assemblies of different specifications and sizes can be installed in the first installation cavity; subsequently, the sound cavity shell can be directly installed on the main body shell without changing the position of the first positioning column of the main body shell.

[0043] Preferably, the first positioning seat 121 is arranged on the left and right sides of the base shell 1201 and the rear side of the rear cover 1202. At least three first positioning posts 111 are provided, and the three first positioning posts 111 are arranged at intervals in a triangle, and one first positioning post 111 is adapted for use with one first positioning seat 121. By providing the first positioning posts 111 arranged at intervals in a triangle, the stability of the sound cavity housing 12 being assembled to the main body shell 11 can be improved, and shaking is not likely to occur.

[0044] The main shell 11 is any one of a TV shell, a radio shell or a projector shell. A sound hole 113 is provided on the side of the main shell 11. After the sound cavity shell 12 is installed on the main shell 11, the speaker assembly 13 is arranged facing the sound hole 113.

[0045] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
