[0032] 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.

[0033] Please also read Figures 1 to 6Now, the bracket assembly applicable to the speaker provided in the embodiment of the present application is described. The bracket assembly applicable to the speaker comprises: a plastic inner shell 10 and a plastic bottom shell 20 .

[0034] The plastic bottom shell 20 is coated on the outer surface of the plastic inner shell 10, and the plastic inner shell 10 is installed with a PCB board 11, and the PCB board 11 is provided with a connector socket 12; the plastic bottom shell 20 is provided with a plug-in area 201, and the plug-in area 201 is inlaid with a metal bracket 21; the plastic bottom shell 20 is provided with a first plug-in interface 202 that penetrates the plastic bottom shell 20 and the metal bracket 21 in the plug-in area 201. When the plastic bottom shell 20 is coated on the plastic inner shell 10, the metal bracket 21 abuts against the upper and lower surfaces of the PCB board 11, and the front end of the connector socket 12 is inserted into the first plug-in interface 202. When the connector plug and the connector socket 12 are plugged in and out, the connector plug is aligned with the first plug-in interface 202, and inserted into the plug-in interface of the connector socket 12 from the first plug-in socket, so that the plug-in connection between the connector plug and the connector socket 12 can be realized.

[0035] Specifically, by providing a plastic bottom shell 20 inlaid with a metal bracket 21, when the plastic bottom shell 20 is covered with the plastic inner shell 10, the upper and lower surfaces of the PCB board 11 can be supported, and the connector socket 12 can be inserted into the first plug interface 202; such a structure can support and limit the connector socket 12 and the PCB board 11, and it is not easy to move the connector socket 12 and the PCB board 11 during plug-in connection, and prevent the connection between the connector socket 12 and the PCB board 11 from being broken due to external force, thereby improving the service life and reliability of the speaker. At the same time, because the metal bracket 21 can effectively support the PCB board 11, there is no need to glue and fix the metal bracket 21 and the connector socket 12 later; it can not only reduce the production defect rate, but also improve production efficiency.

[0036] In some embodiments of the present application, the plastic inner shell 10 includes a main body shell 101 and a front shell 102 mounted on the upper surface of the main body shell 101, and the PCB board 11 is screwed and connected to the bottom of the front shell 102. A plurality of first plug-in protrusions 1011 are evenly spaced on the edge of the main body shell 101, and a plurality of first plug-in slots 1021 are evenly spaced on the edge of the front shell 102. When the front shell 102 is mounted on the main body shell 101, the plurality of first plug-in protrusions 1011 are inserted into the plurality of first plug-in slots 1021 one by one.

[0037] Specifically, two stoppers 103 are provided on one side of the main shell 101 facing the plug-in area 201, and the two stoppers 103 are arranged at intervals to form a first limiting notch 104; after the plastic bottom shell 20 covers the outer surface of the plastic inner shell 10, the connector socket 12 is located in the first limiting notch 104. The two stoppers 103 are arranged to surround the first limiting notch 104, which can limit the left and right position of the connector socket 12, so as to ensure that the connector socket 12 will not be moved left and right during subsequent plug-in and unplug connections, so as to improve the connection stability between the connector socket 12 and the PCB board 11, and the connection between the connector socket 12 and the PCB board 11 is not prone to breakage.

[0038] Further, the main shell 101 is provided with a first support column 105, and the first support column 105 is located on the side of the stopper 103 away from the first limiting notch 104; the top of the first support column 105 is provided with a first screw hole 106, and the metal bracket 21 is provided with a first through hole 215. When the first through hole 215 and the first screw hole 106 are coaxially arranged, the first through hole 215 can be screwed into the first screw hole 106 by passing a screw through the first through hole 215. Preferably, the metal bracket 21 includes a main body 211, a first bent portion 212 bent backward at the bottom of the main body 211, and a second bent portion 213 bent forward at the top of the main body 211, and the first bent portion 212 and the second bent portion 213 are used to be embedded in the plastic of the plastic bottom shell 20. By arranging the first bending portion 212 and the second bending portion 213 to be embedded in the plastic of the plastic bottom shell 20, the strength of the plugging area 201 of the plastic bottom shell 20 is improved to ensure that the first plugging interface 202 can provide reliable support force to the front end of the connector socket 12, thereby further improving the limiting effect of the connector socket 12, ensuring that the connector socket 12 is not easily displaced by external force during plugging and unplugging, thereby improving the connection firmness and reliability between the connector socket 12 and the PCB board 11, and preventing the connector between the connector socket 12 and the PCB board 11 from breaking.

[0039] In more detail, the left and right sides of the top of the main body 211 are bent backward to form first folded ears 214, and the first through hole 215 runs through the upper and lower surfaces of each first folded ear 214; the bottom of the first folded ear 214 and the top of the first support column 105 correspond to the top and bottom surfaces of the PCB board 11. The cross section of the first support column 105 is circular, and the top of the first support column 105 is provided with a first limiting protrusion 1051, and the diameter of the first limiting protrusion 1051 is smaller than the diameter of the first support column 105; the PCB board 11 is provided with a first limiting opening 111, and the first limiting protrusion 1051 can be inserted into the first limiting opening 111. Such a structure can not only limit the position of the PCB board 11 in the up and down direction, but also limit the position of the PCB board 11 in the left and right direction, thereby improving the assembly stability of the PCB board 11 and the connector, and preventing deviation.

[0040] Preferably, the first folded ear 214 and the first bent portion 212 are arranged in parallel with each other at a vertical distance, the bottom surface of the first folded ear 214 abuts against the top surface of the PCB board 11, and the top surface of the first bent portion 212 abuts against the bottom surface of the connector socket 12. The main body 211 is provided with two first via holes 2111 penetrating through its front and rear surfaces, and the two first via holes 2111 are arranged one by one corresponding to the two sides of the first plug interface 202. When the metal bracket 21 and the plastic bottom shell 20 are inlay-molded, the plastic of the plastic bottom shell 20 can be embedded in the first via holes 2111 to improve the connection firmness between the metal bracket 21 and the plastic bottom shell 20.

[0041] It can be understood that the bracket assembly suitable for speakers provided in the present application can be applied to flat-panel speakers or box-type speakers. By providing a metal bracket 21, a plastic inner shell 10 and a plastic bottom shell 20, the PCB board 11 and the connector socket 12 can be limited and locked, thereby eliminating the gluing operation, improving the connection firmness, reducing production costs, and shortening production time.

[0042] In some other embodiments of the present application, a cover 22 is disposed on the top of the plastic bottom shell 20, and the plastic inner shell 10 is covered by the cover 22. The PCB board 11 can produce sound through the speaker assembly by welding the speaker assembly.
