[0030] The utility model provides a speaker housing 100. Figures 1 to 4 , Figure 1 It is a structural schematic diagram of an existing speaker; Figure 2 This is a three-dimensional structural diagram of an embodiment of a speaker housing 100 of the present utility model; Figure 3 It is a schematic diagram of a partially exploded structure of an embodiment of a speaker housing 100 of the utility model; Figure 4 It is a schematic diagram of the exploded structure of an embodiment of the speaker housing 100 of the present invention.
[0031] In the embodiment of the present utility model, Figures 2 to 4 As shown, the speaker housing 100 proposed by the utility model, the first circuit board and the second circuit board are arranged in the speaker housing 100, and the speaker housing 100 includes:
[0032] A protective shell 10, wherein the protective shell 10 is provided with an avoidance hole 11, and a first circuit board is arranged in the protective shell 10; and
[0033] The bracket 20 is installed in the avoidance hole 11. The bracket 20 is provided with a accommodating cavity 211 and an opening 221. The second circuit board is arranged in the accommodating cavity 211. The opening 221 is connected to the accommodating cavity 211 and extends in the direction of the first circuit board. The connecting line passes through the accommodating cavity 211 and the opening 221 to connect the first circuit board and the second circuit board.
[0034] The first circuit board and the second circuit board are arranged at different installation positions and installation directions of the speaker housing 100. Specifically, the first circuit board is arranged above the protective shell 10, and the second circuit board is arranged in the accommodating cavity 211 of the bracket 20. The connecting wire connects the first circuit board and the second circuit board to connect and conduct the first circuit board and the second circuit board. In one embodiment, the first circuit board can be a main board, and the second circuit board can be an audio input circuit board.
[0035] like Figure 1 As shown, the existing speaker has holes at the back of the bracket 20 and the top of the housing 10, and there is a large gap between the two holes. In order to prevent the connection wire from being exposed on the bracket 20 and being damaged by other parts, it is often necessary to use a wire duct 50 to connect the two holes, and the connection wire passes through the wire duct 50 to connect the first circuit board and the second circuit board. However, the wire duct 50 will occupy too much space in the speaker, and the installation of the wire duct 50 is relatively complicated. It is also very troublesome to pass the connection wire through the wire duct 50, which makes the operation of connecting the two circuit boards cumbersome.
[0036] In contrast, Figures 2 to 4 As shown, the technical solution of the utility model adopts a avoidance hole 11 provided on the protective shell 10 to facilitate the installation of the bracket 20, so that the bracket 20 can be directly installed on the protective shell 10. The bracket 20 is provided with an opening 221 facing the first circuit board, and the connecting wire on the second circuit board in the bracket 20 can directly pass through the inside of the bracket 20 and pass through the opening 221 to connect to the first circuit board. Since the connecting wire passes directly in the bracket 20, it is not easy to be worn and damaged by other components; there is no need to design and install a wire conduit, and the connecting wire can be connected to the first circuit board and the second circuit board, which is simpler and faster to operate.
[0037] In one embodiment, the avoidance hole 11 on the protective shell 10 is matched with the outer wall surface of the bracket 20, so that the bracket 20 is installed and fixed in the avoidance hole 11. In one embodiment, the top of the bracket 20 is provided with an opening 221, and the opening 221 is arranged toward the first circuit board. The connecting wire can directly pass through the opening 221 inside the bracket 20 and connect with the first circuit board. The connecting wire is not exposed to the outside of the bracket 20, and the connecting wire does not need to pass outside the bracket 20. Therefore, it is not necessary to design a wire conduit to protect the connecting wire, and then it is not necessary to install a wire conduit. The operation of connecting the first circuit board and the second circuit board with the connecting wire is simpler and faster.
[0038] like Figure 4As shown, in order to facilitate the installation of the bracket 20 on the protective shell 10, the protective shell 10 includes a top plate 12 and a side plate 13. The side plate 13 is bent relative to the top plate 12. The top plate 12 is provided with a first mounting hole 121, and the side plate 13 is provided with a second mounting hole 131. The first mounting hole 121 is connected to the second mounting hole 131 to form an avoidance hole 11.
[0039] In one embodiment, the first mounting hole 121 and the second mounting hole 131 on the protective shell 10 are connected to form an avoidance hole 11 for mounting the bracket 20. Since the first circuit board is mounted above the protective shell 10, the distance between the bracket 20 mounted on the protective shell 10 and the circuit board is reduced, and an opening 221 is provided on the top of the bracket 20, the opening 221 faces the first circuit board, and the connection line on the second circuit board in the bracket 20 can directly pass through the opening 221 to connect with the first circuit board.
[0040] Specifically, Figures 2 to 4 As shown, the bracket 20 includes a receiving portion 21 and a limiting portion 22. The receiving portion 21 is provided with a receiving cavity 211. The limiting portion 22 is extended toward the top plate 12. The limiting portion 22 is provided with an opening 221. The receiving portion 21 is installed in the first mounting hole 121, and the limiting portion 22 is installed in the second mounting hole 131.
[0041] In one embodiment, the accommodating cavity 211 of the bracket 20 is used to install the second circuit board. The limiting portion 22 of the bracket 20 is provided with an opening 221, the opening 221 is communicated with the accommodating cavity 211, and the opening 221 is arranged toward the first circuit board. The connection wires on the second circuit board in the accommodating cavity 211 can pass through the opening 221 without passing through the outside of the bracket 20 or the back of the bracket 20, and the operation is simpler and faster.
[0042] The limiting portion 22 can be configured as a cylindrical structure or a C-shaped structure with three sides closed. The limiting portion 22 can protect the connecting wires to prevent the connecting wires from being worn and damaged by other components located at the back of the bracket 20, and can also prevent the connecting wires from being exposed to the outside of the bracket 20 and contaminated by liquid.
[0043] like Figures 2 to 4 As shown, in order to limit the bracket 20 on the avoidance hole 11 of the protective shell 10, a blocking portion 222 is provided on the edge of the limiting portion 22. The blocking portion 222 extends in a direction away from the opening 221 and abuts against the top plate 12.
[0044] When the bracket 20 needs to be installed together with the protection, the bracket 20 is first placed in the avoidance hole 11, the blocking part 222 can be abutted against the top plate 12, and finally the blocking part 222 can be connected to the top plate 12 using the fastener 40 to limit and fix the bracket 20 in the avoidance hole 11.
[0045] Alternatively, if Figures 2 to 4 As shown, a pressing block 212 is protruding outwardly from the edge of the accommodating portion 21 . The pressing block 212 is extended in a direction away from the accommodating cavity 211 , and the pressing block 212 abuts against the side plate 13 .
[0046] In one embodiment, the pressing block 212 abuts against the side plate 13 , and the pressing block 212 and the side plate 13 may be connected together using a fastener 40 to firmly fix the bracket 20 in the avoidance hole 11 .
[0047] In order to prevent liquid from penetrating from the gap between the protective shell 10 and the bracket 20 , a sealing member 30 is interposed between the protective shell 10 and the bracket 20 .
[0048] In one embodiment, the bracket 20 is installed in the avoidance hole 11 of the protective shell 10. There is a gap between the bracket 20 and the protective shell 10. For this reason, a circle of sealing members 30 is sandwiched between the bracket 20 and the protective shell 10 to block the gap between the bracket 20 and the protective shell 10. Specifically, a circle of sealing members 30 is pasted under the bracket 20, and then the bracket 20 is installed in the avoidance hole 11. The sealing members 30 can be clamped by the bracket 20 and the protective shell 10. The sealing members 30 block the gap between the bracket 20 and the protective shell 10, thereby preventing liquid from penetrating from the gap between the protective shell 10 and the bracket 20. Among them, the sealing member 30 can be a sealant, and the sealant can adhere the protective shell 10 to the bracket 20.
[0049] In order to better fix the sealing member 30 , the speaker housing 100 further includes a fastener 40 . The bracket 20 is provided with a fixing hole 23 . The fastener 40 passes through the fixing hole 23 and is connected to the protective shell 10 , so that the protective shell 10 and the bracket 20 clamp the sealing member 30 .
[0050] In one embodiment, the bracket 20 is provided with a fixing hole 23, and the protective shell 10 is provided with a through hole corresponding to the fixing hole 23, and the fastener 40 passes through the fixing hole 23 and the through hole in sequence to connect the bracket 20 and the protective shell 10. The bracket 20 and the protective shell 10 are connected by the fastener 40, thereby limiting and clamping the seal 30. The seal 30 is clamped between the bracket 20 and the protective shell 10 to block the gap between the bracket 20 and the protective shell 10, thereby preventing liquid from penetrating from the gap between the protective shell 10 and the bracket 20. Among them, the fastener 40 can be a screw.
[0051] Furthermore, the fixing holes 23 and the sealing member 30 are staggered, and the fixing holes 23 are arranged at the outer edge of the sealing member 30, so that the fastener 40 is located at the outer edge of the sealing member 30, thereby preventing the sealing member 30 from being squeezed and extruded from the bottom of the bracket 20 when the fastener 40 is screwed into the bracket 20. In one embodiment, the bracket 20 is provided with a plurality of fixing holes 23, and the fasteners 40 are installed one by one with the fixing holes 23. The plurality of fasteners 40 are installed on the bracket 20, and the plurality of fasteners 40 are all located at the outer edge of the sealing member 30, so as to restrict the sealing member 30 between the bracket 20 and the protective shell 10.
[0052] In order to reduce the infiltration of liquid from the connection between the protective shell 10 and the bracket 20 , the sealing member 30 is a sealing ring structure, which is arranged around the edge of the bracket 20 .
[0053] Specifically, the sealing ring is provided with a side ring 31 and a top ring 32, the side ring 31 is connected to the top ring 32, the side ring 31 is sandwiched between the side plate 13 and the pressure block 212, and the top ring 32 is sandwiched between the top plate 12 and the blocking portion 222. And a plurality of fasteners 40 together with the outer wall of the accommodating portion 21 limit the side ring 31 between the pressure plate and the side plate 13 to prevent the side ring 31 from detaching from the pressure plate. Similarly, a plurality of fasteners 40 together with the outer wall of the limiting portion 22 limit the top ring 32 between the top plate 12 and the blocking portion 222 to prevent the top ring 32 from detaching from the blocking portion 222.
[0054] The utility model also proposes a speaker, including a first circuit board, a second circuit board and a speaker housing 100.
