Embodiment
Present by detailed reference embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein, identical label indicates identical parts all the time.Below by referring to accompanying drawing, described embodiment will be described, to explain the present invention.
Fig. 3 shows the sectional perspective schematic diagram of the electro-acoustic element hermetically-sealed construction of the electronic equipment according to the embodiment of the present invention; Fig. 4 shows the partial side schematic view of the assembling process of the electronic equipment of Fig. 3; Fig. 5 shows the partial side schematic view after the electronic equipment assembling of Fig. 3.
With reference to Fig. 3 to Fig. 5, show the electro-acoustic element hermetically-sealed construction of electronic equipment according to an embodiment of the invention.Described electro-acoustic element hermetically-sealed construction comprises sealing shroud 60 and projection 70, sealing shroud 60 surrounds electro-acoustic element 50 and defines the sounding passage 62 of electro-acoustic element 50, projection 70 is given prominence to from the side surface (left surface Fig. 4) of fore shell 10, and contiguous sealing shroud 60 and back cover 20 are arranged, the protuberate of projection 70 higher than or flush the outstanding surface of sidepiece in sealing shroud 60 from fore shell 10, make first to contact with projection 70 when back cover 20 assembles with fore shell 10, with the back cover 20 of conflicting in assembling process.That is, projection 70 and sealing shroud 60 from the part that the sidepiece of fore shell 10 is given prominence to flush mutually or than sealing shroud 60 from the outstanding part of the sidepiece of fore shell 10 more outwardly, make when back cover 20 assembles with fore shell 10, back cover 20 first contacts with projection 70, and the end face of the sealing shroud 60 that can stagger and first not contacting with sealing shroud 60, like this, can not make sealing shroud 60 due to the assembling between front and rear casing intentional deformation, and then cause sealing shroud 60 poor sealing, occur that sound interference or gross distortion even block the phenomenon of vocal hole.
Preferably, projection 70 can form with fore shell 10.The shape of sealing shroud 60 is not limited to have the square of a fillet shown in Fig. 3, can have arbitrary shape according to actual needs.Projection 70 can be two projections 70 with circular arc shown in Fig. 2, and is arranged in the both sides of sealing shroud 60 asymmetrically according to the practical structures of fore shell 10.But quantity and the frame mode of projection 70 are not limited thereto, such as, multiple projections 70 of the surrounding being centered around sealing shroud 60 respectively can be had, or two projections 70 are arranged in the both sides of sealing shroud 60 symmetrically, and the projection 70 of both sides is all set to the edge's (right side projection as in Fig. 2) near back cover 20.The shape of projection 70 is not limited to the circular arc projection shown in Fig. 3-5, it can also be spherical other suitable shape such as grade of semicircle, as long as projection 70 has round and smooth shape, back cover 20 can be made to flush with the outside of sealing shroud 60 with between fore shell 10 erecting stage or keep certain intervals, thus back cover 20 can not make sealing shroud 60 intentional deformation, do not hinder again the assembling of back cover 20 and fore shell 10 simultaneously and be separated.
In addition, the material of sealing shroud 60 can be silica gel or foam.The material of back cover 20 can be plastic cement.In addition, the hardness being formed with the hardness ratio back cover 20 of the fore shell 10 of projection 70 is large, thus when back cover 20 assembles, and projection 70 can by back cover 20 supporting deformation, to reduce the extruding that back cover 20 pairs of sealing shrouds 60 may cause.In addition, back cover 20 also can be provided with the groove 80 mated with projection 70, after being assembled to fore shell 10 at back cover 20, holding projection 70.Like this, as in Figure 3-5, because projection 70 is arranged near the upper end of sealing shroud 60, and the size of projection 70 is less than the size of sealing shroud 60, therefore after fore shell 10 and back cover 20 assemble, overlapping portion 61 is still there is, to guarantee the sealing of hermetically-sealed construction to electro-acoustic element 50 between back cover 20 and sealing shroud 60.
In addition, in the electronic equipment that motherboard shown in electro-acoustic element hermetically-sealed construction according to the present invention can be arranged on as shown in Figure 1, Figure 2 or the contiguous fore shell 10 of circuit board 40 are arranged, namely, sounding passage 62 is positioned at the electronic equipment of the top of electro-acoustic element 50, also can be arranged in the electronic equipment of contiguous back cover 20 setting of motherboard 40 as shown in Fig. 3 to Fig. 5, that is, sounding passage 62 is positioned at the electronic equipment of the below of electro-acoustic element 50.
Preferably, having according to the electronic equipment of the electro-acoustic element hermetically-sealed construction of the embodiment of the present invention can be portable mobile termianl, such as, and mobile phone, panel computer, handheld device, digital player etc.Use the electro-acoustic element of electro-acoustic element hermetically-sealed construction can for being positioned at loud speaker (Speaker) on the upper and lower side of electronic equipment or left and right side or microphone (MIC) etc.
The housing that electro-acoustic element hermetically-sealed construction according to the present invention can effectively reduce electronic equipment in assembling process to the extruding of sealing shroud, the poor sealing preventing sealing shroud from producing because of crimp and then the sound interference phenomenon occurring between electro-acoustic element, or cause due to crimp the problem blocking vocal hole, and structure is simple, anti-extrusion Be very effective.
Although show and described exemplary embodiments more of the present invention, but those skilled in the art should understand that, when not departing from by the principle of the present invention of claim and its scope of equivalents thereof and spirit, can change these embodiments.
