[0039] Please refer to the following: Figures 1 to 7 The present application will now describe the plug-in board structure for a speaker according to several embodiments. The plug-in board structure for a speaker includes: a plug-in board 10 and a cover plate 20.

[0040] The plug board has multiple plug interfaces for connector assembly, and a cover plate 20 is mounted on the front surface of the plug board 10. The cover plate 20 has a number of clearance openings equal to the number of plug interfaces and capable of exposing the plug interfaces; or, the cover plate 20 has one or more clearance openings for exposing the plug interfaces and a covering part for covering one or more plug interfaces.

[0041] Specifically, by providing a cover plate 20 on the front surface of the plug-in board 10, the cover plate 20 can be configured to expose the plug interface or cover the plug interface according to actual needs, so that the plug-in board 10 only exposes the required plug interface, thus presenting a plug-in board structure with different plug interfaces to adapt to the use of different specifications of speakers, thereby improving the versatility and compatibility of the plug-in board 10; moreover, this method of changing the different specifications of the plug-in board 10 does not require changing the structure of the injection mold or adding a corresponding injection mold, which can further reduce the manufacturing cost of the plug-in board structure.

[0042] First Embodiment

[0043] Please refer to the following: Figures 1 to 3 This is the specific structure of the plug-in board structure for a speaker provided in the first embodiment of this application.

[0046] It should be noted that the circuit board can also be assembled and fixed by using a snap-fit ​​protrusion and a snap-fit ​​groove, or by using adhesive.

[0047] More specifically, the cover sheet 20 is a PC sheet, with a thickness between 0.5 cm and 2.0 cm.

[0054] Specifically, the circuit board 30 is provided with a DC connector 31 that can be exposed to the DC connector 11, an AUX-R connector 32 that can be exposed to the AUX-R connector 12, an AUX-L connector 33 that can be exposed to the AUX-L connector 13, a LINE connector 34 that can be exposed to the LINE connector 14, an OPTICAL connector 35 that can be exposed to the OPTICAL connector 15, and an ARC connector 37 that can be exposed to the ARC connector 17.

[0055] Understandably, when the plug board is equipped with the second cover plate 202, the plug board structure belongs to the second specification plug board structure. The second specification plug board structure can expose the DC connector 31, AUX-R connector 32, AUX-L connector 33, LINE connector 34, OPTICAL connector 35 and ARC connector 37.

[0056] Third Embodiment

[0057] Please refer to the following: Figures 6 to 7 This is a specific structure of the plug-in board structure for a speaker provided in the third embodiment of this application. The structure of the third embodiment of this application is generally the same as that of the first embodiment, except that the cover plate is a third cover plate 203.

[0058] In the third embodiment of this application, the third cover 203 is provided with a DC clearance opening 21 for exposing the DC connector 11, an AUX-R clearance opening 22 for exposing the AUX-R connector 12, a LINE clearance opening 24 for exposing the LINE connector 14, an OPTICAL clearance opening 25 for exposing the OPTICAL connector 15, a USB clearance opening 26 for exposing the USB connector 16, an ARC clearance opening 27 for exposing the ARC connector 17, and a second cover portion 29 for covering the AUX-R connector 12.

[0059] DC clearance 21, AUX-R clearance 22, LINE clearance 24, OPTICAL clearance 25 and ARC clearance 27 all penetrate the front and rear surfaces of the third cover plate 203.

[0060] Specifically, the circuit board is provided with a DC connector 31 that can be exposed in the DC interface 11, an AUX-R connector 32 that can be exposed in the AUX-R interface 12, a LINE connector 34 that can be exposed in the LINE interface 14, an OPTICAL connector 35 that can be exposed in the OPTICAL interface 15, a USB connector 36 that can be exposed in the USB interface 16, and an ARC connector 37 that can be exposed in the ARC interface 17.

[0061] Understandably, when the plug board is equipped with the third cover plate 203, the plug board structure belongs to the third specification plug board structure. The third specification plug board structure can expose the DC connector 31, AUX-R connector 32, LINE connector 34, OPTICAL connector 35, USB connector 36 and ARC connector 37. The circuit board is a third specification circuit board equipped with the DC connector 31, AUX-R connector 32, LINE connector 34, OPTICAL connector 35, USB connector 36 and ARC connector 37.

[0062] Therefore, the speaker plug-in board structure provided in this application can form a first-specification plug-in board structure based on the combination of the first cover plate 201 and the plug-in board, a second-specification plug-in board structure based on the combination of the second cover plate 202 and the plug-in board, and a third-specification plug-in board structure based on the combination of the third cover plate 203 and the plug-in board. In fact, the number and specifications of each plug-in interface of the first-specification plug-in board structure, the second-specification plug-in board structure, and the third-specification plug-in board structure are the same. Only by changing the position of the avoidance hole of the first cover plate 201, the second cover plate 202, and the third cover plate 203 and adding the setting of the cover part, the exposure or non-exposure of the plug-in hole can be changed, thereby realizing multiple plug-in board structures. This multiple plug-in board structure does not require the addition of injection molds or changes to the specific structure of injection molds, which can reduce manufacturing costs and improve the versatility of plug-in boards.
