Abstract
The utility model provides an acoustics chamber on a mobile terminal. The acoustics chamber comprises a loudspeaker, an upper cover and a lower cover. The upper cover and the lower cover are fixedly connected together to form an accommodation space. The loudspeaker is installed in the accommodation space so as to form a front chamber and a rear chamber. The front chamber and the rear chamber are spaced apart from each other through sealing materials. According to the technical scheme of the utility model, due to the adoption of novel materials for preparing the upper cover and the lower cover, a novel structure and a novel preparation process, the entire thickness of the acoustics chamber is effectively reduced.
Description
Technical field
The utility model relates to mobile terminal device, more particularly relates to the portable terminal acoustic cavity of a kind of New Type Material and structure.
Background technology
In recent years, the portable terminal product is more and more thinner, use traditional in the past acoustic cavity structure can't satisfy the lightening requirement of product, in order to realize the lightening of portable terminal product, need to reduce the thickness of loam cake and lower cover, upper cover plate and lower cover that present technology generally adopts metal material to make replace original plastic material, thereby reduction product thickness, yet because the conductive characteristic of metal material, tend to antenna is affected, so adopt the cover plate up and down of metal material can not satisfy the lightening requirement of portable terminal product, be badly in need of a kind of new material and replace original material.Original structure also needs to make the change of a little simultaneously.
Summary of the invention
In order to address the above problem, a kind of portable terminal acoustic cavity that the utility model provides, comprise loudspeaker, also comprise a loam cake and a lower cover, described loam cake and lower cover are fixedly connected to form an accommodation space, described loudspeaker are installed in the described accommodation space and form an ante-chamber and a back cavity, separate by encapsulant between described ante-chamber and the described back cavity.
Preferably, described loam cake comprises a upper cover plate and a loam cake body that is connected with described upper cover plate, and described lower cover comprises a lower cover and a lower cover body that is connected with described lower cover.
Preferably, described upper cover plate and described lower cover adopt non-conducting material respectively.
Preferably, described non-conducting material is zirconia, aluminium oxide, glass reinforcement plate, pottery, contains the composite material of zirconia material or contain the composite material of aluminium oxide.
Preferably, the minimum thickness of the minimum thickness of described upper cover plate and described lower cover is respectively 0.1mm.
Preferably, described upper cover plate and lower cover comprise with the connected mode of described loam cake body and lower cover body that embedding and injection molding, glue are bonding respectively, hot melt, adhesive tape paste.
Preferably, one of two of described loam cake and lower cover or two are provided with perforate or fluting.
Preferably, described loam cake comprises a upper cover plate and a loam cake body that is connected with described upper cover plate, and described lower cover only comprises the loam cake body.
Preferably, described lower cover comprises a lower cover and a lower cover body that is connected with described lower cover, and described upper cover plate only comprises the loam cake body.
The upper cover plate that the utility model provides and lower cover adopt non-conductive high-strength material separately respectively, make described upper cover plate and lower cover minimum thickness separately can reach 0.1mm respectively, and non-conducting material can reduce the influence to antenna, and adopted new structure and technology, effectively reduced the integral thickness of portable terminal acoustic cavity.
Description of drawings
The structural representation of the embodiment that Fig. 1 provides for the utility model;
The structural representation of another embodiment that Fig. 2 provides for the utility model.
Embodiment
Referring to the accompanying drawing that the utility model embodiment is shown, hereinafter the utility model will be described in more detail.Yet the utility model can be with many multi-form realizations, and should not be construed as the restriction of the embodiment that is subjected in this proposition.On the contrary, it is abundant and complete open in order to reach proposing these embodiment, and makes those skilled in the art understand scope of the present utility model fully.In these accompanying drawings, for clarity sake, may amplify size and the relative size in layer and zone.
Embodiment one
As shown in Figure 1, a kind of novel portable terminal acoustic cavity that the utility model provides, comprise loudspeaker 5, it also comprises a loam cake and a lower cover, described loam cake and lower cover are fixedly connected to form an accommodation space, loudspeaker 5 are installed in the described accommodation space and form ante-chamber 4 and back cavity 3, separate by encapsulant 7 between ante-chamber 4 and the back cavity 3, and the back cavity 3 after separating is a seal chamber.
Wherein said loam cake comprises upper cover plate 1 and the loam cake body 8 that is connected with upper cover plate 1, and described lower cover comprises lower cover 2 and the lower cover body 9 that is connected with lower cover.Wherein the shape of upper cover plate 1 and lower cover 2 is not limited to the shape that the present embodiment accompanying drawing is given, specifically according to the needs design upper cover plate 1 of product and the shape of lower cover 2.
Embodiment two
As shown in Figure 1, a kind of novel portable terminal acoustic cavity that the utility model provides, comprise loudspeaker 5, it also comprises a loam cake and a lower cover, described loam cake and lower cover are fixedly connected to form an accommodation space, loudspeaker 5 are installed in the described accommodation space and form ante-chamber 4 and back cavity 3, separate by encapsulant 7 between ante-chamber 4 and the back cavity 3, and the back cavity 3 after separating is a seal chamber.
Wherein said loam cake comprises upper cover plate 1 and the loam cake body 8 that is connected with upper cover plate 1, and lower cover includes only lower cover body 9.
Embodiment three
As shown in Figure 1, a kind of novel portable terminal acoustic cavity that the utility model provides, comprise loudspeaker 5, it also comprises a loam cake and a lower cover, described loam cake and lower cover are fixedly connected to form an accommodation space, loudspeaker 5 are installed in the described accommodation space and form ante-chamber 4 and back cavity 3, separate by encapsulant 7 between ante-chamber 4 and the back cavity 3, and the back cavity 3 after separating is a seal chamber.
Wherein said lower cover comprises lower cover 2 and the loam cake body 9 that is connected with lower cover 2, and loam cake includes only loam cake body 8.
The upper cover plate 1 of Chu Xianing and lower cover 2 are connected with lower cover body 9 to combine with loam cake body 8 respectively and form loam cake and lower cover in the above-described embodiment, and its connected mode can be that embedding and injection molding, glue are bonding, hot melt, adhesive tape stickup etc.;
Because antenna 6 is attached to this acoustic cavity surface, upper cover plate 1 and lower cover 2 will reduce the influence to antenna performance as far as possible, also to keep frivolous characteristic simultaneously, so upper cover plate 1 and lower cover 2 adopt non-conductive high-strength material to make separately respectively in this example, described non-conductive high-strength material can be materials such as zirconia, aluminium oxide, glass reinforcement plate, the composite material that contains zirconia material, the composite material that contains aluminium oxide, pottery; What the thickness of the upper cover plate 1 of Xing Chenging and lower cover 2 can be controlled like this is very low, minimumly can reach 0.1mm, also very little to the influence of antenna 6 simultaneously.
