Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of acoustic component of the present utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
Fig. 1 is structural representation of the present utility model.As shown in Figure 1, the utility model provides a kind of mobile terminal, comprises fore shell 1, back cover 2, is arranged at acoustic component 3, printed circuit board 4(PCB-Printed Circuit Board between fore shell 1 and back cover 2) and conducting-heat elements 5.In the present embodiment, the bottom of back cover 2 is provided with the sound chamber 21 for holding acoustic component 3, sticks the foam 6 of restricted acoustic component 3 displacements in sound chamber 21, and the vibrating diaphragm face of acoustic component 3 attaches on foam 6.Between acoustic component 3 and printed circuit board 4, be provided with the spatial accommodation for holding conducting-heat elements 5.In the present embodiment, conducting-heat elements 5 is heat conductive silica gel in the form of sheets, and for the heat storage capacity that ensures that it is good, the thickness of heat conductive silica gel is about 0.1mm.Shown in Fig. 1, Fig. 2, conducting-heat elements 5 is arranged in the spatial accommodation that acoustic component 3 and printed circuit board 4 form, and the first surface of conducting-heat elements 5 is pasted and is connected with the magnetic texure surface 31 of acoustic component 3, and second contacts with the copper face 41 of PCB4 ground connection.In the present embodiment, in order to reach better heat-conducting effect, the first surface of conducting-heat elements 5 covers the magnetic texure surface 31 of acoustic component 3 completely.So, the heat that acoustic component 3 produced at work, can effectively conduct to PCB4 by conducting-heat elements 5, the mode of original heat loss through radiation is optimized for to the radiating mode of heat conduction, increase heat transference efficiency, the unfailing performance of acoustic component is promoted greatly, reduced the possibility that acoustic component damages.After assembling, under the extruding of back cover 2, acoustic component 3, conducting-heat elements 5, PCB4 are crimped on together successively, keep reliably contact.
In order further to improve radiating effect, the copper face 41 of PCB4 ground connection can contact with fore shell 1 by metallic support 8, so, the heat of acoustic component 3 conducts the Copper Foil to PCB4 by conducting-heat elements 5, by the higher Copper Foil of these thermal conductivitys, heat is disseminated to the surface of PCB4, again by metallic support 8, the dissipation of heat that acoustic component 3 is produced, to complete machine, has increased area of dissipation greatly, has improved rate of heat dissipation.
In the present embodiment, acoustic component 3 is an independent Speaker and the two-in-one device of Receiver.Acoustic component 3 also can be the Speaker and the Receiver that are positioned over respectively in upper and lower two sound chambeies, also can be three Speaker to meet audiophile's stereo experience.The material of conducting-heat elements 5 also can be selected graphite.Conducting-heat elements 5 itself has the performance that good springiness, heat-sinking capability are strong, the load-carrying ability that withstands shocks is large, not only can heat conduction, and can also control acoustic component 3 and be shifted, when receiving external impacts, mobile terminal protects acoustic component 3.
In the prior art; the protection of acoustic component is by sacrificing audio-frequency index or manufacturing original realization; and the present embodiment by having set up conducting-heat elements 5 between acoustic component 3 and PCB4; the heat that acoustic component 3 produces can be conducted on PCB4 uniformly by conducting-heat elements 5; the mode of original heat loss through radiation is converted into the radiating mode of heat conduction; Copper Foil on PCB4 is as hot good conductor; hole spreads on whole plate PCB4 heat uniformly ordinatedly; increase area of dissipation, strengthened the radiating effect of acoustic component 3.Then, then by metallic support 8, effectively heat is further spread to complete machine from PCB4, thus, the heat that acoustic component 3 produces is able to Quick diffusing, to recover normal temperature.Improvement of the present utility model has not only strengthened the reliability of acoustic component, has also increased the useful life of acoustic component and even complete machine simultaneously.
Above embodiment is only unrestricted in order to the technical solution of the utility model to be described, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spiritual scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
