INSTRUCTIONS: 1. Technical Field of the Invention The present invention relates to a sound chamber structure, and more particularly to a sound cell structure of a mobile phone. [Prior Art] The η octet cavity of the existing mobile phone is usually integrally molded with the casing. ❹Because of the low strength of the plastic material, the injection-molded structure of the remaining sound chamber and the casing also has the disadvantage of low strength. If it is considered to increase the strength of the integral structure of the racquet chamber and the casing, the method commonly used is to increase the thickness of the injection molding. However, the method of increasing the thickness of the injection molding will inevitably increase the thickness of the mobile phone product, which is not conducive to the thin and light design of the mobile phone. © [Summary of the Invention] In view of the above, it is necessary to provide a thinned sound chamber structure having high strength. A sound chamber structure includes a metal body and a metal cavity. The metal cavity includes a bottom surface and side walls extending vertically along both sides of the bottom surface, and the side end edges and the top edge of the side walls form at least one cavity connecting surface. The metal body includes a first frame, a second frame, and a beam that vertically connects the frames. The first frame forms a first body connecting surface at a cavity connecting surface corresponding to the end edge of the first frame. The connecting portion of the second frame at the end corresponding to the top edge of the cavity extends in a direction parallel to the beam 201021581 to extend a connecting portion, the connecting portion ^ ^ , the connecting surface. The first body connecting surface and the bottom end == the cavity i of the library and the body connecting surface of the first side of the body and the cavity connecting surface are respectively fixed to each other, and forming an injection molding on the surface of the metal cavity Pieces.

And forming an injection molded part on the metal body and the metal cavity surface layer which are fixed to each other to strengthen the strength of the entire sound cavity structure. The use of the higher strength metal material to manufacture the sound cavity structure can relatively reduce the product thickness under the same strength condition. 'Conducive to the product's thin and light design. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. As shown in FIG. 1 , a sound cavity structure provided by an embodiment of the present invention includes a metal body 1 相互 and a metal cavity 12 connected to each other. The metal cavity 12 includes a bottom surface 120 and sidewalls 122 extending vertically upward along both side edges i2〇a of the bottom surface 120. The top edge 124 and the side edge edge 125 of the side wall 122 extend outwardly and are bent to form a cavity connecting surface 128. The top edge 124 of the side wall 122 is further provided with a plurality of first auxiliary engaging structures, such as a first hook 130, a first engaging flange 131 or a first engaging opening 132, and the like. The first auxiliary snap-fit structure is used to effect the connection between the metal cavity 12 and other structures, such as a sound chamber cover, to enhance the functionality of the metal cavity 12. The metal body 10 includes a first side 棺1〇1 and a 201021581 边框 second frame 102 which are parallel to each other, and a beam 104 that vertically connects the first frame 1〇1 and the second frame 102. The first frame 1〇1 extends outwardly at a cavity corresponding to the cavity connecting surface 128 of the side edge edge 125 and is bent to form a first body connecting surface 1 corresponding to the cavity connecting surface 128. 〇 8. The second frame 102 extends at a distal end of the cavity connecting surface 128 corresponding to the top edge 124 in a direction parallel to the beam 1〇4, and a connecting portion 106 is formed at the end of the connecting portion 106. The cavity connecting surface 128 corresponds to the second body connecting surface 1〇9. The first frame 101, the second frame 102, and the beam 1〇4 are further provided with a plurality of first-level snap-fit structures, such as a second hook 150 and a second slot 151t to form an opening 152 to implement the The connection between the metal body 1〇 and other structures' enhances the functionality of the metal body 1〇. As shown in FIG. 2, the first body connecting surface 1〇8 of the metal body 1〇 and the second body connecting surface 1〇9 of the metal body 10 and the cavity connecting surface on the side end edge 125, respectively. The cavity connection faces 128 on the 128 and top edges 124 are secured to each other by laser spot welding. As shown in FIG. 3, after the metal body 10 and the metal cavity 12 are fixed, the injection molding member 14 covering the metal metal cavity 12 is formed by the method of forming a plastic molding, thereby further improving the installation. The overall strength of the 曰 cavity, 1 structure 1 is described. Because the injection molded part 14 only plays the role of overall reinforcement and protection without the need to support the entire cavity cavity, the thickness can be made thinner to balance the sound cavity structure thinning in the present invention. The material of the body 1 and the metal cavity 12 is a metal material of a strong strength, such as a domain alloy, to increase the impact strength of the structure 1 of the sound cavity 201021581. The material of the injection molded part 14 is a polycarbonate containing glass fiber to reduce the water shrinkage of the injection molded part 14, thereby providing a better fixing effect. Compared with the prior art, the sound chamber structure provided by the present invention can form the mating body connecting surface and the cavity connecting surface on the joint portion of the metal body and the metal cavity, so that the metal body and the metal cavity can be welded. The method is fixed to each other's and through the method of insert molding _ forming an injection molded part on the metal body and the metal cavity surface layer which are fixed to each other to increase the strength of the entire sound cavity structure. The use of a higher strength metal material to make the cavity structure relatively reduce the product thickness under the same strength conditions is advantageous for the thin and light design of the product. In addition, those skilled in the art can also make other people in the spirit of the present invention, and variations made in accordance with the spirit of the present invention should be included in the scope of the present invention.
