Embodiment
Describe the utility model below with reference to the accompanying drawings and in conjunction with the preferred embodiments in detail.
Fig. 1 shows the structural representation according to the upturning lid 10 of the utility model mobile phone, wherein, is provided with the loud speaker of sound chamber sealing in this upturning lid.Here, term " sealing of sound chamber " refers to the sealing in sound chamber behind the loud speaker, and the sound chamber can not seal before the loud speaker, leaves opening 11 on the fore shell 1 of upturning lid, so that the sound that is sent of loud speaker spreads out of from opening 11 places uniquely.
Fig. 2 shows the STRUCTURE DECOMPOSITION schematic diagram of upturning lid 10 shown in Figure 1.As shown in the figure, upturning lid 10 comprises fore shell 1, screw 2, sound chamber cap assemblies 3, loud speaker 4, back cover 5.Wherein, have accommodation space 51 on the back cover 5, this accommodation space 51 is by 3 sealings of sound chamber cap assemblies.Sound chamber cap assemblies 3 is installed on the back cover 5 by screw 2, simultaneously loud speaker 4 is pressed in the accommodation space 51.Fore shell 1 and back cover 5 utilize screw 6 and other screw (not shown) to be screwed onto together, form the upturning lid of mobile phone.
Fig. 3 shows the STRUCTURE DECOMPOSITION schematic diagram of the sound chamber cap assemblies 3 shown in Fig. 2.As shown in the figure, sound chamber cap assemblies 3 comprises sound chamber lid 31, is adhered to the sound insulating pad 32,33 that the sound chamber is covered the sound insulating pad 34,35 of 31 inboards, is pasted on sound insulating pad 31 outsides.Have sound openings 31A on the sound insulating pad 31, near sound openings 31A, have via hole 31B, run through for the screw post in the spatial accommodation 51 of back cover 5.Sound insulating pad 31 also has part 31G and the 31H that extends in spatial accommodation 51 outsides, has screw base hole 31C, 31D and location hole 31E and 31F on this part 31G and the part 31H, so that sound chamber cap assemblies can and be spirally connected fixing with respect to back cover 5 location.
In the present embodiment, sound insulating pad 32,33 and sound insulating pad 34,35 are made by the foam material, sound insulating pad 34,35 is made of the first foam pad 34 around the sound openings 31A that is attached to sound chamber lid 31 and the second foam pad 35 that is attached to the first foam pad, 34 peripheries, and the certain first foam pad and the second foam pad also can be formed and not separated by a monoblock foam pad. Sound insulating pad 32,33 can be made of the 4th foam pad 33 that sticks on the 3rd foam pad 32 around the sound openings 31A and stick on around the via hole 31B, can certainly be formed and not separated by a monoblock foam pad.
It can also be seen that from Fig. 3 the size of sound insulating pad 35 is greater than the size of sound insulating pad 34, this sound insulating pad 35 is corresponding with the edge of the accommodation space 51 of back cover 5, shows the sectional area in loud speaker sound chamber.Here mentioned " loud speaker sound chamber " is construed as formed sealing sound chamber, sealed back, sound chamber behind the loud speaker.In addition, expect easily that sound insulating pad also can not be pasted on the sound chamber and cover, and when assembling, use separately.
Fig. 4 shows the scheme of installation of sound chamber cap assemblies, and Fig. 5 shows the structural representation of the upturning lid for the treatment of screw lock.As shown in Figure 4 and Figure 5, be provided with screw post 53 in the accommodation space 51 of loud speaker, after turning over back cover 5 on loud speaker 4 is packed into, push down loud speaker 4 with sound chamber cap assemblies 3, wherein foam pad 34 and foam pad 35 will work, and the continuous pad 34 of bubble separates the preceding sound chamber and the sound chamber, back of loud speaker 4 under the stress deformation of screw 2 lockings, and foam pad 35 is supported by back cover 5 corresponding ribs 52, stressed back foam pad 35 is compressed, thereby the position separates the sound chamber, back and the external world in this section.
The screw via hole 31B of sound chamber cap assemblies 3 is used to place screw post 53, has foam pad 33 around this via hole 31B, this foam pad 33 seals sound chamber, back when screw 6 (Fig. 2) is locked fore shell 1 and back cover 5 fully, compresses sound chamber cap assemblies 3 simultaneously, prevents sound chamber lid stress deformation and warpage.This warpage appears on two angles of not establishing the screw base hole of sound chamber cap assemblies usually.In addition, by steeping continuous pad 32, can come out from the front of loud speaker 4 and be unlikely to side leakage to produce quaver by enable voice like this being closed of the side, preceding sound chamber of loud speaker 4.
By above description as can be seen,, only need a small amount of thickness (setting up due to the lid of sound chamber) that increases upturning lid, can on the basis in big sound chamber, realize the sealing in sound chamber according to the utility model.The loud speaker sound chamber enclosed construction that is comprised in the above-mentioned mobile phone can also be applied in other electronic equipment, for example is applied in MP3, MP4, game machine or the palmtop PC, to improve the tonequality of loud speaker.
Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
