[0025] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as a limitation of the utility model.
[0026] As Figure 1 and Figure 2As shown, the loudspeaker 100 of the embodiment of the utility model, including first casing 1 and connector, connector has the PCB board 2 and first connecting part 3 of connection, PCB board 2 is embedded in first casing 1, and at least part section of first connecting part 3 is located outside first casing 1 and forms connecting terminal.
[0027] It should be understood that the PCB board 2 in the connector is embedded in the first casing 1, so that the integration between the connector and the first casing 1 can be more effectively improved, so that the outer protrusion size of the connector arranged in the first casing 1 is smaller. With the above structure, there is no need to arrange a wire harness between the loudspeaker 100 and the connector, the problem of abnormal sound generated when the wire harness collides is solved, the process step of wrapping the wire harness with foam is also reduced, and the cost is saved. When assembling, the loudspeaker 100 of the embodiment of the utility model can adapt to a smaller assembly space, and the problem that the loudspeaker 100 is difficult to assemble due to limited space is solved.
[0028] In some embodiments, the PCB board 2 is connected with the first casing 1 by in-mold injection. Specifically, the PCB board 2 is assembled with the first casing 1 of the loudspeaker 100 by in-mold injection, and the in-mold injection connection of the PCB board 2 can be completed synchronously in the molding process of the first casing 1, the process step is more simplified, and the stability of the molded structure is better.
[0029] Further, the PCB board 2 and the first connecting part 3 are integrally arranged. It should be understood that the first connecting part 3 and the PCB board 2 are integrally arranged, the integration degree is higher, the size of the outer protrusion can be more effectively controlled, for example, the first connecting part 3 and the PCB board 2 form a PCI-E interface after being connected, at this time, the PCB board 2 can select a standard part with a PCI-E interface.
[0030] Optionally, the first connecting part 3 is a Pin needle 31, when the PCB board 2 and the first connecting part 3 are integrally arranged, the Pin needle 31 is integrated on the PCB board 2, without the need to customize the Pin needle 31, thereby reducing the cost.
[0031] In some embodiments, the PCB board 2 and the first connecting part 3 are separately arranged, and part of the first connecting part 3 is embedded in the first casing 1.
[0032] That is, the PCB board 2 and the first connecting part 3 are two relatively independent parts, when the first connecting part 3 and the PCB board 2 are embedded in the first casing 1, they are connected to each other, which can fix the relative position of the two and has better stability, and also can achieve the purpose of reducing the outer protrusion size.
[0033] Further, the first connecting component 3 is connected with the first shell 1 by in-mold injection. That is, the partial segment of the first connecting component 3 is fixed in the first shell 1 by in-mold injection, and the in-mold injection connection of the PCB board 2 and the first connecting component 3 can be completed synchronously during the molding of the first shell 1, the stability of the molded structure is good, and the external convex size can be reduced.
[0034] In some embodiments, the outer side of the first shell 1 is arched along a first direction and forms a convex portion 11, and at least partial segments of the PCB board 2 and the first connecting component 3 are arranged in the convex portion 11, and the first direction is the thickness direction of the first shell 1.
[0035] It should be understood that the loudspeaker 100 further comprises a second shell 4 connected with the first shell 1 and defining a containing cavity, and the outer side of the first shell 1 away from the second shell 4 is arched along a first direction and forms a convex portion 11, and at least partial segments of the PCB board 2 and the first connecting component 3 are arranged in the convex portion 11.
[0036] The containing cavity is used to arrange a transducing element of the loudspeaker 100, the transducing element is connected with the PCB board 2, and at least partial segments of the PCB board 2 and the first connecting component 3 are arranged in the convex portion 11, so that the connector is in-mold injection connected with the first shell 1 without affecting the containing space inside the containing cavity, the overall structure size of the loudspeaker 100 with the connector is reduced, and the assembly is facilitated.
[0037] In some embodiments, the first connecting component 3 comprises a plurality of Pin needles 31 arranged side by side. It should be understood that the plurality of Pin needles 31 are arranged side by side along a third direction, and the number of Pin needles 31 is determined according to the actual application needs, for example, the number of Pin needles 31 in the embodiment of the utility model is 2.
[0038] Further, the spacing between the adjacent two Pin needles 31 is not greater than 3.5 mm. That is, by integrally arranging the Pin needle 31 with the PCB board 2, or by in-mold injection connecting the Pin needle 31 with the first shell 1 together, the spacing between the adjacent Pin needles 31 can be further reduced, which is more conducive to miniaturization of the corresponding components and easier to realize platformization.
[0039] For example, the spacing C between the adjacent two Pin needles 31 is 3.5 mm, 3.4 mm, 3.3 mm, 3.15 mm, 2.94 mm, 2.7 mm, 2.63 mm, 2.5 mm or 2.47 mm. According to the space size requirement of the mounting position of the loudspeaker, by reducing the spacing between the adjacent two Pin needles 31, the connecting end connected therewith can also be miniaturized, which is more convenient for plug-in assembly between components.
[0040] In some embodiments, the protrusion 11 has a size in the first direction less than or equal to 10.85 mm, a size in the second direction less than or equal to 16.241 mm, and a size in the third direction less than or equal to 11.2 mm; wherein the third direction is the arrangement direction of the Pin needle 31, and the first direction, the second direction and the third direction are orthogonal to each other.
[0041] It should be understood that the first direction is the up-down direction shown in the figure, the second direction is the front-rear direction shown in the figure, and the third direction is the left-right direction shown in the figure. The size of the protrusion 11 in the first direction is the height of the protrusion 11 protruding from the first shell 1, and the reduction of the size of the protrusion 11 in the first direction can reduce the size of the entire loudspeaker 100 in the first direction.
[0042] The second direction is the insertion direction of the connection terminal of the connector in the loudspeaker 100 and the connection terminal of the wire end, and the reduction of the size of the protrusion 11 in the second direction can provide more operation space for the insertion and removal of the connection terminal of the wire end, facilitating disassembly and assembly work.
[0043] The reduction of the size of the protrusion 11 in the third direction can make the size of the connection terminal of the connector in the loudspeaker 100 smaller, and accordingly the size of the connection terminal of the wire end connected with the connector in the loudspeaker 100 can also be adaptively reduced, so as to miniaturize the size of the components and facilitate the installation of the loudspeaker 100 in a space-limited position.
[0044] For example, the size B of the protrusion 11 in the first direction is 10.85 mm, 10.7 mm, 10.2 mm or 9.7 mm.
[0045] For another example, the size D of the protrusion 11 in the second direction is 16.241 mm, 16 mm, 15.5 mm, 15.36 mm or 14 mm.
[0046] For another example, the size A of the protrusion 11 in the third direction is 11.2 mm, 11 mm, 10.6 mm, 9 mm, 8.35 mm, 7.5 mm or 7 mm.
[0047] The selection of the sizes of the protrusion 11 in the first direction, the second direction and the third direction is determined according to the space requirement of the installation position of the loudspeaker 100. When the installation space size is small and the operation is inconvenient when connected with other components, the size in the corresponding direction is reduced to ensure that no interference occurs between the components and normal disassembly and assembly connection with other components can be achieved. When the space in a certain direction is sufficient, the size limit of the protrusion 11 in the corresponding direction can be appropriately relaxed.
