Description

Technical Field

[0001] This invention belongs to the field of acoustics, and specifically relates to a loudspeaker device and an electronic device. Background Technology

[0002] The hot plate welding machine adopts a pull-out plate structure. Heat is transferred from the heating plate to the welding surfaces of the upper and lower plastic heating parts via electric heating. This melts the surfaces, and the heating plate is then quickly withdrawn. The molten surfaces of the two heating parts fuse, solidify, and become one. The entire machine is a frame structure, composed of three main plates: an upper template, a lower template, and a hot template. It is also equipped with a hot mold and upper and lower plastic cold molds. The operation is pneumatically controlled. It is mainly suitable for welding plastic parts such as household appliances, car lights, and automotive containers. The heating power and mold size can be set according to the size of different plastic parts to achieve welding of various plastic workpieces. It is simple to operate and convenient to use.

[0003] In typical hot plate welding, the weld beads need to be squeezed against each other during the welding process. As a result, molten material overflows to the outside after the weld beads are welded. When the squeezing force is large, the molten material will splash to both sides, causing glue overflow after the product is hot-pressed, which affects the product's appearance. Summary of the Invention

[0004] The purpose of this invention is to provide a loudspeaker device and an electronic device to at least partially solve the problems in the prior art.

[0005] The first aspect of the present invention provides a loudspeaker device, comprising: A first housing, a second housing, and a speaker unit disposed inside the first housing and the second housing; The first housing is provided with a first welding rib and a first baffle wall forming a first overflow trough with the first welding rib at the position where it connects with the second housing; The second housing is provided with a second welding rib and a second baffle wall forming a second overflow trough with the second welding rib at the position where it connects with the first housing; The second welding rib and the first welding rib are welded together to connect the first shell and the second shell into one unit, and the first retaining wall and the second retaining wall are respectively located on the outer edge of the welding position.

[0006] The loudspeaker device provided by the present invention may also have the following additional technical features: In one specific embodiment of the present invention, the height of the first retaining wall is greater than that of the first welding rib; the height of the second retaining wall is greater than that of the second welding rib, and the first retaining wall and the second retaining wall are respectively located on both sides of the welding position; The welding method is hot plate welding.

[0007] In one specific embodiment of the present invention, the first retaining wall and the second shell form a first fracture, and the second retaining wall and the first shell form a second fracture.

[0008] In one specific embodiment of the present invention, the opposing surfaces of the first welding rib and the second welding rib are both inclined surfaces, and the inclined surfaces gradually expand from the outside of the speaker device to the inside of the speaker device.

[0009] In one specific embodiment of the present invention, the first retaining wall is located outside the first housing, the second retaining wall is located inside the second housing, and the second break is located above the welding position.

[0010] In one specific embodiment of the present invention, the outer edge of the second housing extends away from the second weld rib to form a stepped surface, and the stepped surface forms the first break with the first retaining wall.

[0011] In one specific embodiment of the present invention, the welding height of the first welding rib and the second welding rib is the same as the height of the first retaining wall or the second retaining wall.

[0012] In one specific embodiment of the present invention, the height difference between the inclined surfaces of the first welded rib and the second welded rib is 0.05-0.2 mm.

Detailed Implementation

[0020] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0021] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0022] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0023] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0024] like Figure 1-4 As shown, the first aspect of the present invention provides a loudspeaker device, the loudspeaker device including a first housing 10, a second housing 20, and a loudspeaker unit 30 disposed inside the first housing 10 and the second housing 20; The first housing 10 is provided with a first welding rib 101 and a first baffle 102 forming a first overflow trough 103 with the first welding rib 101 at the position where it connects with the second housing 20; The second housing 20 is provided with a second welding rib 201 and a second baffle 202 forming a second overflow trough 203 with the second welding rib 201 at the position where it connects with the first housing 10; The second welding rib 201 and the first welding rib 101 are welded together to connect the first shell 10 and the second shell 20 into one unit, and the first retaining wall 102 and the second retaining wall 202 are respectively located on the outer edge of the welding position.

[0025] In the above structure, the first welding rib 101 of the first housing 10 and the second welding rib 201 of the second housing 20 are correspondingly arranged and can be connected by welding, thereby connecting the first housing 10 and the second housing 20 to form a receiving cavity for accommodating the speaker unit 30. To prevent molten material from splashing from the first welding rib 101 and the second welding rib 201 during hot plate welding, the first housing 10 and the second housing 20 are also provided with a first baffle 102 and a second baffle 202. During welding, the first baffle 102 and the second baffle 202 are respectively located on both sides of the welding position, and can block the molten material splashed outward from the first welding rib 101 and the second welding rib 201 during welding, thereby preventing the molten material from flowing to the outside of the hot plate welding structure, reducing the difficulty of subsequent cleaning, and thus improving the aesthetics of the overall structure.

[0026] In one specific embodiment of the present invention, the height of the first retaining wall 102 is greater than that of the first welding rib 101; the height of the second retaining wall 202 is greater than that of the second welding rib 201, and the first retaining wall 102 and the second retaining wall 202 are respectively located on both sides of the welding position; The welding method is hot plate welding.

[0027] In the above structure, by limiting the height of the first baffle 102 and the second baffle 202, the first baffle 102 and the second baffle 202 can block the welding position throughout the welding process, thereby preventing molten material from splashing.

[0028] In one specific embodiment of the present invention, the first retaining wall 102 and the second housing 20 form a first break 104, and the second retaining wall 202 and the first housing 10 form a second break 204.

[0029] The first break 104 and the second break 204 are formed by the distance between the first baffle 102, the second baffle 202 and the corresponding first shell 10 and second shell 20 after welding. The above structure is suitable for avoiding the failure of hot pressing to be completed smoothly due to the formation of a sealed cavity between the first baffle 102 and the second shell 20, and between the second baffle 202 and the first shell 10, thereby ensuring the connection strength of the first shell 10 and the second shell 20.

[0030] In one specific embodiment of the present invention, the opposing surfaces of the first welding rib 101 and the second welding rib 201 are both inclined surfaces, which gradually expand from the outside of the speaker device to the inside of the speaker device. Specifically, the side of the top surface of the first welding rib 101 facing away from the first baffle 102 is higher than the other side, and the side of the top surface of the second welding rib 201 facing the second baffle 202 is higher than the other side. That is, in the inclined surfaces of the first welding rib 101 and the second welding rib 201, the protruding parts are arranged opposite each other and both face the second baffle 202. Therefore, when the first welding rib 101 and the second welding rib 201 are heated, the protruding parts in the inclined surfaces will melt and accumulate first, while the melt on the other side will be relatively reduced. Therefore, during the hot pressing process, the melt extruded to the side of the second baffle 202 will increase and flow into the second overflow groove, while the melt extruded to the side of the first baffle 102 will be relatively reduced, thereby reducing the amount of melt flowing out of the first break 104 and keeping the second shell 20 clean.

[0031] In one specific embodiment of the present invention, the first retaining wall 102 is located outside the first housing 10, the second retaining wall 202 is located inside the second housing 20, and the second break 204 is located above the welding position.

[0032] Specifically, the first break 104 formed by the first baffle 102 and the second housing 20 is located below the welding position, and the second break 204 formed by the second baffle 202 and the first housing 10 is located above the welding position. Although the first baffle 102 and the second baffle 202 can block the molten material splashed during hot pressing, a small amount of molten material will still flow downward along the second welding rib 201. By setting the first baffle 102 on the outside of the first housing 10 and the second baffle 202 on the inside of the second housing 20, the second break 204 above the welding position can be located inside the receiving cavity. This allows the material flowing downward on the inner side of the welding position to enter the second overflow groove, thereby preventing the material from flowing into the receiving cavity and sticking to other structures, thus ensuring the safety of the structure inside the receiving cavity.

[0033] In one specific embodiment of the present invention, the outer edge of the second housing 20 extends away from the second welding rib 201 to form a stepped surface, and the stepped surface forms the first fracture 104 with the first retaining wall 102. The inner edge of the first housing 10 extends away from the first welding rib 101 to form a stepped surface to form the second fracture 204 with the second retaining wall 202. By using the stepped surface to cooperate with the first retaining wall 102 and the second retaining wall 202 to form the first fracture 104 and the second fracture 204, the height of the first retaining wall 102 and the second retaining wall 202 can be guaranteed, thereby making the height of the first retaining wall 102 and the second retaining wall 202 basically equal to that of the first welding rib 101 and the second welding rib 201 after welding. This better shields the molten material during the hot pressing process, thus ensuring the aesthetics of the structure.

[0034] In one specific embodiment of the present invention, the height difference of the inclined surfaces in the first welding rib 101 and the second welding rib 201 is 0.05-0.2 mm. Preferably, the height difference of the inclined surfaces in the first welding rib 101 and the second welding rib 201 is 0.1 mm.

[0035] In one specific embodiment of the present invention, the first welding rib 101 and the second welding rib 201 are at the same height, the first retaining wall 102 and the second retaining wall 202 are at the same height, and the height difference between the first retaining wall 102 and the first welding rib 101 is 1-3 mm. Preferably, the height difference between the first retaining wall 102 and the first welding rib 101 is 2 mm.

[0036] In one specific embodiment of the present invention, the welding height of the first welding rib 101 and the second welding rib 201 is the same as the height of the first retaining wall 102 or the second retaining wall 202.

[0037] In one specific embodiment of the present invention, the width of the first welding rib 101 and the second welding rib 201 is not less than 2.5 mm, and the width of the first overflow groove 103 and the second overflow groove 203 is not less than 2 mm.

[0038] Preferably, the height of the first welding rib 101 and the second welding rib 201 is 3mm, the width is 2.5mm, the height difference of the inclined surfaces is 0.1mm, and the overlap height during welding is 1mm; the height of the first retaining wall 102 and the second retaining wall 202 is 5mm, the width is 1.2mm, and the width of the first overflow groove and the second overflow groove is 2mm.

[0039] In another aspect, the present invention provides an electronic device comprising the speaker device described in any one of the foregoing descriptions.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
