DETAILED DESCRIPTION

[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0054] It should be noted that the present application involves directionality indication, such as front and back, up and down, left and right, etc., which refers to the relative positional relationship between each component in the normal wearing posture, for example, the shell is towards the end of the face as the rear end, and the end away from the face as the front end, etc. If the posture changes, the directionality indication will also change accordingly; if the present application involves the description of "first", "second", etc., the description of "first", "second", etc. is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features.

[0055] By Figures 1 to 3 The embodiment of the present application discloses a kind of temple structure, including temple body 1, temple body 1 includes metal composite shell 11 and inner shell 12 that are buckled together;Metal composite shell 11 and inner shell 12 at least enclose a closed first installation cavity, speaker 2 is provided in the first installation cavity, and the front vibration end of speaker 2 is towards inner shell 12;Speaker 2 separates first installation cavity into mutually independent front cavity 13 and rear cavity 14, and front cavity 13 corresponds with the front vibration end;Sound hole 15 that is communicated with front cavity 13 and sound hole that is communicated with rear cavity 14 are provided on inner shell 12 or metal composite shell 11;Metal composite shell 11 includes metal shell 111 made of high damping metal material and first plastic shell 112 arranged on the inner side of metal shell 111.

[0056] The sound hole is not only set to reduce weight, but also can improve the volume of rear cavity 14 (communicate with external), improve low-frequency performance;Rear cavity sound wave generated by speaker 2 itself will be reflected to the metal composite shell 11 opposite to rear cavity 14, since the metal shell 111 in the metal composite shell 11 is made of high damping metal material, it has good vibration absorption performance, without additional complex damping structure, it can reduce the resonance and resonance of sound, maintain the resolving power and clarity of sound, and improve the overall acoustic performance.

[0057] Wherein, high damping metal material includes lead, tin, magnesium copper alloy or magnesium lithium alloy material, preferably magnesium lithium alloy material with lighter weight, which can further reduce weight.

[0058] In an embodiment, metal composite shell 11 and inner shell 12 also enclose a second installation cavity independent of the first installation cavity, and mainboard module 3 or battery is installed in the second installation cavity;Relief opening 18 is provided on the first plastic shell 112 corresponding to the second installation cavity, and the heating device in the mainboard module 3 or the battery is abutted with the metal shell 111 through the relief opening 18 (preferably, conductive silicone grease is provided between the heating device and the metal shell 111 to improve heat transfer efficiency);The top end and the bottom end of the inner shell 12 or the metal composite shell 11 are respectively provided with sound hole communicated with the rear cavity 14. Figure 2As shown in the figure, the sound leakage hole arranged at the top end of the inner shell 12 is the first sound leakage hole 16, and the sound leakage hole arranged at the bottom end of the inner shell 12 is the second sound leakage hole 17. The heat generated by the heat generating device or the battery in the mainboard module 3 is transferred to the metal shell 111, and part of the heat of the metal shell 111 is transferred to the outside space through heat conduction, and the other part is transferred to the rear cavity 14 through heat conduction. With the increase of working time, a high-temperature area is formed in the rear cavity 14, that is, a temperature difference is formed, and cold air will enter from the second sound leakage hole 17 at the bottom, generating a thrust on the hot air inside the rear cavity 14, and the hot air will be transferred from the first sound leakage hole 16 at the top to the outside space, forming a micro-convection, and improving the heat dissipation of the whole machine. By setting in this way, without additional heat dissipation module, the heat dissipation can be realized only by the two sound leakage holes and the metal composite shell 11, which is conducive to further meeting the development needs of light weight, thin and small size of the product.

[0059] In another embodiment, a hollow mounting frame 123 is arranged on the inner wall of the inner shell 12 corresponding to the first mounting cavity, and an annular limiting step surface (i.e. a stepped structure) is arranged at the opening end of the mounting frame 123. The loudspeaker 2 is sealingly mounted at the opening end of the mounting frame 123, and the edge portion of the front vibrating end abuts against the annular limiting step surface. The front vibrating end, the inner shell 12 and the mounting frame 123 form the front cavity 13, and the remaining first mounting cavity is the rear cavity 14. Preferably, an adhesive layer is coated on the annular limiting step surface, which can ensure the sealing of the front cavity 13 after the loudspeaker 2 is mounted. A sealing ring 19 is arranged between the parts of the inner shell 12 and the metal composite shell 11 for enclosing the first mounting cavity. In this way, the sealing of the first mounting cavity can be further improved.

[0060] In another embodiment, the first plastic shell 112 includes a first connecting segment 1121 and a first hanging ear segment 1122, and the metal shell 111 is buckled on the outer side of the first connecting segment 1121 (the first hanging ear segment 1122 is located outside the metal shell 111). The inner shell 12 includes a second plastic shell 121 and a carbon fiber shell 122. The second plastic shell 121 includes a second connecting segment 1211 for buckling with the first connecting segment 1121 and a second hanging ear segment 1212 for buckling with the first hanging ear segment 1122. The carbon fiber shell 122 is buckled on the side of the second connecting segment 1211 away from the metal composite shell 11 (the second hanging ear segment 1212 is located outside the carbon fiber shell 122). In this way, the weight of the hanging ear portion can be reduced, the elasticity of the hanging ear portion can be ensured, and the comfort of wearing can be improved. This is conducive to further meeting the development needs of light weight, thin and small size and comfort of the product.
