In the description of the present utility model, it should be noted that the terms "mounted," "connected," and "coupled" are to be construed broadly, as well as, for example, fixedly coupled, detachably coupled, or integrally coupled, unless otherwise specifically indicated and defined. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art. In the description of the embodiments, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.

In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the present embodiment, as shown in fig. 1, a speaker apparatus is designed, which includes a first housing 100, a second housing 200, and a speaker module 300.

The first housing 100 and the second housing 200 are combined to form a receiving cavity 400, and the speaker module 300 is mounted in the receiving cavity 400.

In the present embodiment, the side of the first housing 100 and the second housing 200 close to the speaker module 300 is the inner side, and the side far from the speaker module 300 is the outer side.

In the welding fusion process of the first housing 100 and the second housing 200, welding is performed by adopting a vibration fusion mode of a vibration machine. In the vibration fusion welding process, the generated glass fiber fragments overflow to two sides, and the glass fiber fragments overflow inwards and enter the accommodating cavity 400 formed by surrounding the first shell 100 and the second shell 200, so that the acoustic performance of the loudspeaker module 300 in the accommodating cavity 400 is caused. The glass fiber chips overflow outwards and can overflow out of the first shell 100 and the second shell 200, so that the attractiveness of the loudspeaker device is affected.

Therefore, in the present embodiment, it is necessary to avoid glass fiber fragments generated during the vibration fusion welding of the first housing 100 and the second housing 200 from entering into the accommodating cavity 400 or overflowing to the outside of the first housing 100 and the second housing 200.

In the present embodiment, as shown in fig. 2 and 3, the first housing 100 includes a first mating surface 110 and a plurality of first welding ribs 120 protruding from the first mating surface 110 toward the second housing 200.

The first mating surface 110 is an annular surface. The plurality of first welding beads 120 are vertically formed on the first mating surface 110.

The first welding bead 120 is an annular welding bead. The first welding rib 120 is disposed around the circumference of the first mating surface 110.

In this embodiment, the second housing 200 includes a second mating surface 210, and the second mating surface 210 is an annular surface. The second mating surface 210 has a groove 211, and the groove 211 is an annular groove. A plurality of annular second welding ribs 220 are formed in the groove 211, the second welding ribs 220 are arranged in the groove 211 in a surrounding mode, and protrude from the bottom of the groove 211 to the side of the first butt joint surface 110.

The second welding rib 220 is disposed around the circumference of the second mating surface 210.

The first plurality of welding beads 120 are in one-to-one correspondence with the positions of the second plurality of welding beads 220.

The first welding ribs 120 and the second welding ribs 220 at the corresponding positions are respectively subjected to vibration welding fusion, and a plurality of integral welding fusion ribs are formed after the first welding ribs 120 and the second welding ribs 220 are in one-to-one corresponding welding fusion. The welding fusion bead is ring-shaped, and the burr receiving cavity 600 is formed between two adjacent welding fusion beads.

Glass fiber scraps are generated during the shock welding fusion process of the first welding rib 120 and the second welding rib 220, and overflow to both sides. Glass fiber fragments can enter the accommodating cavity 400 when overflowing inwards, so that the acoustic performance is affected, and glass fiber fragments can overflow to the outside of the first shell 100 and the second shell 200 when overflowing outwards, so that the attractiveness is affected.

The flash accommodating cavity 600 is located between adjacent welding fusion ribs, and can accommodate glass fiber fragments that overflow inwards and outwards when the first welding rib 120 and the second welding rib 220 are in vibration welding fusion.

Since the flash accommodating cavity 600 is isolated from the accommodating cavity 400 and the first and second housings 100 and 200, glass fiber chips overflowing into the flash accommodating cavity 600 will not enter the accommodating cavity 400 and overflow out of the first and second housings 100 and 200, so that the acoustic performance and the aesthetic property of the speaker device will not be affected.

The glass fiber chips generated in the shock welding fusion of the first welding rib 120 at the middle position and the second welding rib 220 at the middle position may be received in the burr receiving chambers 600 at both sides thereof.

Only the inner side of the innermost welding fusion bead and the outer side of the outermost welding fusion bead may have the possibility that glass fiber chips enter the accommodating cavity 400 and the outer sides of the first and second cases 100 and 200.

And because all the welding fusion ribs are positioned in the groove 211, the groove 211 further plays a role of accommodating the overflowed glass fiber scraps.

Further, the welding fusion surface of the first welding rib 120 and the second welding rib 220 is located in the groove 211, so as to further improve the blocking effect of the groove 211 on overflowed glass fiber fragments.

As shown in fig. 1, in the present embodiment, the number of the first welding rib 120 and the second welding rib 220 is two. In this case, the number of burr receiving cavities 600 is one.

One half of glass fiber scraps generated by the shock welding fusion of the two first welding beads 120 and the two second welding beads 220 are contained in the flash containing cavity 600, and the other half of glass fiber scraps are contained in the grooves 211.

In this embodiment, in order to improve the capability of the groove 211 to block the glass fiber fragments from overflowing, the distance between the welding fusion surface 500 and the bottom surface of the groove 211 is smaller than the distance between the welding fusion surface 500 and the notch of the groove 211, i.e. the welding fusion surface is closer to the bottom surface of the groove 211, so as to improve the blocking effect of the groove 211.

In order to ensure that the welding fusion face 500 is closer to the bottom surface of the groove 211, the height of the first welding rib 120 needs to be greater than the height of the second welding rib 220.

And, under the premise of meeting the requirements of a vibration fusion welding process, the height of the first welding rib 120 is increased as much as possible, and the height of the second welding rib 220 is reduced, so that the welding fusion surface 500 is ensured to be closest to the bottom surface of the groove 211 to the greatest extent, and accordingly glass fiber fragments generated in the welding fusion process are contained in the groove 211 as much as possible.

In the embodiment, due to the limitation of space, the widths of the plurality of second welding ribs 220 formed in the groove 211 and the first welding rib 120 formed on the first mating surface 110 are relatively small, and the welding amount of the plurality of welding fusion surfaces 500 together can meet the welding process requirement.

Because the length of the first welding rib 120 is longer and the width is narrower, in order to ensure the strength of the first welding rib 120, the root portions of the plurality of first welding ribs 120 are connected to form an integral first welding rib base 121, which is beneficial to improving the structural strength of the first welding rib 120.

In this embodiment, in order to ensure that the burr-containing cavity 600 can contain glass fiber chips generated in the vibration fusion welding process of the adjacent first welding bead 120 and second welding bead 220, the height of the burr-containing cavity is required to be equal to or greater than the height of the portion of the first welding bead 120 extending to the first welding bead base 121. The width of the burr receiving chamber 600 is not smaller than the width of the first welding rib 120 and is not smaller than the width of the second welding rib 220. Such that the volume of flash receiving cavity 600 is greater than half the sum of the volumes of the adjacent two weld-melted amounts.

The welding fusion amount is the reduction amount of the sum of the volumes of the first welding rib 120 and the second welding rib 220 before the vibration welding fusion compared with the total volume of the first welding rib 120 and the second welding rib 220 after the vibration welding fusion molding in the vibration welding fusion process.

In this embodiment, the height of flash housing chamber 600 is not less than 1.5mm.

In the present embodiment, the groove 211 is surrounded by a first retaining wall 230 and a second retaining wall 240 formed on the second mating surface 210. In this embodiment, the first retaining wall 230 and the welding fusion rib located at the innermost side enclose to form the first flash accommodating groove 250. The second retaining wall 240 and the welding fusion rib located at the outermost side are surrounded to form a second flash accommodating groove 260. Namely, the inner side wall of the groove 211 and the innermost welding fusion rib enclose to form a first flash accommodating groove 250, and the outer side wall of the groove 211 and the outermost welding fusion rib enclose to form a second flash accommodating groove 260.

The first burr retaining groove 250 is formed with a first open end 251 adjacent to the first mating surface 110.

The second flash accommodating groove 260 is formed with a second open end 261 near the first mating surface 110.

The welding fusion face 500 is remote from the first and second open ends 251, 261, thereby reducing spillage of glass fiber chips during the shock welding fusion process.

In this embodiment, the first flash receiving groove 250 is used to receive the portion of the glass fiber chip that overflows to the inside during the shock fusion welding of the first welding bead 120 and the second welding bead 120.

The second flash accommodating groove 260 is used for accommodating the portion of the glass fiber scraps generated in the process of vibration fusion welding of the first welding rib 120 and the second welding rib 120, which overflows to the outside.

The first burr retaining groove 250 has the same volume as the second burr retaining groove 260.

In the process of vibration welding fusion of the first welding rib 120 and the second welding rib 220, the second butt joint surface 210 gradually approaches the first butt joint surface 110, and in order to avoid vibration fusion of the second butt joint surface 210 and the first butt joint surface 110, a gap 700 needs to be formed between the first butt joint surface 110 and the second butt joint surface 210 after the first welding rib 120 and the second welding rib 220 are formed by vibration fusion.

Since the groove 211 is formed on the second aligning surface 210, the gap 700 formed between the first aligning surface 110 and the second aligning surface 210 is a gap between the top surface of the first retaining wall 230 and the top surface of the second retaining wall 240 and the first aligning surface 110.

Namely, the height of the welded and fused formed first welding rib 120 and second welding rib 220 is greater than the height of the first retaining wall 230 and the second retaining wall 240.

However, in order to avoid the glass fiber scraps generated during the vibration fusion process of the first welding rib 120 and the second welding rib 220 from overflowing from the gap 700, the height of the gap 700 is not too large.

In this embodiment, the first housing 110 and the second housing 210 are disposed up and down, and the second housing 210 is located below the first housing 110, so that glass fiber scraps not only laterally overflows under the force action in the vibration welding fusion process, but also falls under the action of gravity, so that the amount of glass fiber scraps falling into the first flash accommodating groove 250 and the second flash accommodating groove 260 can be increased to a certain extent, and the glass fiber scraps are reduced from overflowing from the first opening end 251 and the second opening end 261.

For the first housing 110 and the second housing 210 that are disposed up and down, at this time, the second welding rib 220 serves as a support portion for vibration welding fusion, and the first welding rib 120 is placed on the second welding rib 220 for vibration welding fusion, so that the first welding rib 120 can be stably placed on the second welding rib 220, and the width of the second welding rib 220 needs to be greater than that of the first welding rib 120.

In another aspect, the present utility model further provides an electronic device, including a speaker device, where the structure of the speaker device is referred to in the embodiments of the speaker device of the present utility model and the descriptions of fig. 1 to 3, and are not repeated herein.
