Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one
Please refer to Fig. 1, Fig. 2 and Fig. 3, there is shown a kind of closed loudspeaker cavity for mobile terminal that the utility model embodiment one provides, for convenience of explanation, illustrate only the part relevant to the utility model embodiment, details are as follows:
The present embodiment be provided for mobile terminal closed loudspeaker cavity comprise upper cover plate 1 and lower cover 2, described upper cover plate 1 is fixedly connected with lower cover 2 and surrounds the hollow cavity with enclosure space, also comprise and be arranged at loud speaker 3 in described enclosure space and circuit board 4, the shell foot of described loud speaker 3 and the routing region 41 of described circuit board 4 are electrically connected, described lower cover 2 is provided with hardware 5, described circuit board 4 to be installed on lower cover 2 and to be electrically connected with described hardware 5, described hardware 5 has contact jaw 51, described lower cover 2 is provided with the through hole adapted with contact jaw 51, contact jaw 51 stretches out from this through hole.
Wherein, what circuit board 4 adopted is FPC flexible circuit board, described lower cover 2 is provided with the mounting groove 6 holding described loud speaker 3, one end of FPC flexible circuit board is pasted onto on this mounting groove 6 by the mode of gum, the FPC flexible circuit board other end is communicated with hardware 5 by the mode of welding, below just can guarantee that loud speaker 3 and hardware 5 are conductings, the contact jaw 51 of hardware 5 stretches out from the through hole that lower cover 2 adapts and contacts with the shell fragment on Mobile terminal main board, thus ensure the mainboard conducting of whole loudspeaker and mobile terminal, preferably, in order to strengthen the electric conductivity of contact jaw 51, gold-plated on contact jaw 51.
Flexible circuit board is that the one made for base material with polyimides or polyester film has height reliability, excellent flexible printed circuit.Have the advantages that distribution density is high, lightweight, thickness is thin, bending property is good.
FPC flexible circuit board, by being fixed on the positioning with under type, offers location hole 42 on the circuit board 4, and the position of the corresponding described location hole 42 of described lower cover 2 is provided with positioning convex 7.Thus FPC flexible circuit board is located, then be fixed by the mode of one end gum other end welding.
In the present embodiment, one end of described upper cover plate 1 and lower cover 2 is that strip forms seal audio cavity, described hardware 5 is arranged in sealing sound chamber, and the other end of described upper cover plate 1 and lower cover 2 is the those widened sections being provided with described mounting groove 6, and then forms an asymmetric cavity body structure.
Known by reference to the accompanying drawings, the seal audio cavity that one end of described upper cover plate 1 and lower cover 2 is formed is irregular strip; Described those widened sections is rectangle, this those widened sections with one of seal audio cavity long be total to while, the another side of described those widened sections protrudes from another long limit of described seal audio cavity.
Be understandable that, for a kind of closed loudspeaker cavity for mobile terminal of the utility model, seal audio cavity also can adopt the strip of other shape, and those widened sections can not adopt rectangle equally and adopt other shape, if those widened sections relative to seal audio cavity side for widening shape.
In the present embodiment, upper cover plate 1 and lower cover 2 are fixedly connected with by the mode of ultrasonic bonding.Ultrasonic bonding is the high-tech technology of welding thermoplastic articles, and various thermoplastic cement part all can use ultrasonic fusing process, and does not need solubilizer, bonding agent or other supplement.Its advantage is increase many times of productivity ratio, reduces costs, and improves the quality of products and keeps the safety in production.By upper weldment, ultrasonic energy is sent to welding zone, because the welding zone i.e. interface place acoustic resistance of two welding is large, therefore can produces localized hyperthermia.Again due to plastics poor thermal conductivity, can't distribute in time for the moment, be gathered in welding zone, cause the contact-making surface of two plastics to melt rapidly, after adding certain pressure, make it be fused into one.After ultrasonic wave fails, allow pressure durations a few second, make its coagulation forming, so just form a firm strand, reach the object of welding, weld strength can close to raw material intensity.
This kind that the present embodiment provides is for the structural form of the closed loudspeaker cavity of mobile terminal, both perfect audio quality can have been ensured, can reduce costs again, universal standard part loud speaker is used to realize the loudspeaker cavity of closed, without the need to doing formulation part, optimize structural manufacturing process simultaneously, structural manufacturing process is simpler, overall structure can be done thinner relative to traditional integral type loudspeaker cavity on thickness, be applicable to variously have on the electronic product of audio playing function, to adapt to pursue more and more thinner fashion trend for electronic product thickness at present.
