Abstract
The utility model provides a mobile terminal increasing the size of a sound cavity of a loudspeaker. The mobile terminal comprises a first shell and a circuit board. The circuit board is arranged inside the first shell. The circuit board is provided with the loudspeaker and an element lower than the loudspeaker. A height difference space of the loudspeaker and the element is taken as an expanding sound cavity of the loudspeaker. According to the mobile terminal provided by the utility model, the height difference space of the loudspeaker and the element is taken as the expanding sound cavity of the loudspeaker so that the size of the sound cavity of the loudspeaker is enlarged and the sound effect of the loudspeaker is improved.
Description
Technical field
The utility model relates to field of mobile terminals, particularly relates to a kind of portable terminal that increases loudspeaker sound cavity volume.
Background technology
Along with the development of society and the progress of science and technology, portable terminal, for example mobile phone has become instrument indispensable in people's daily life, and therefore, the user is also more and more higher to the requirement of performance, structure and the outward appearance of mobile phone.
The sound chamber all is to be pressed on the circuit board by foam to be sealed to form behind the general loudspeaker, like this, will reserve very big space on the circuit board and paste foam, and be subjected to spatial limitation, and volume big components and parts can not be piled up in the inside.Under many circumstances, piled up restriction, foam can only be attached to around the speaker body, and the loudspeaker sound cavity volume of Xing Chenging is not up to standard in this manner, may cause the loudspeaker performance bad.
The utility model content
The utility model provides a kind of portable terminal that increases loudspeaker sound cavity volume, to solve loudspeaker sound cavity volume problem not up to standard in the prior art.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of portable terminal that increases loudspeaker sound cavity volume is provided, comprises:
First housing; And
Circuit board is located in described first housing, and described circuit board is provided with loudspeaker and short in the element of described loudspeaker;
Wherein, utilize the difference in height space of described loudspeaker and described element as described expansion sound chamber.
According to the utility model one preferred embodiment, described first housing comprises:
Described loudspeaker are accommodated in the first sound chamber, and by forming sealing between foam and the described circuit board;
Described element below is located in the second sound chamber, is connected with the described first sound chamber, and seals by cover plate.
According to the utility model one preferred embodiment, described foam is bonded between the described first sound chamber and the described circuit board by gum.
According to the utility model one preferred embodiment, described cover plate is bonded on the described second sound chamber by gum.
According to the utility model one preferred embodiment, described element is radome or connector.
The beneficial effects of the utility model are: be different from the situation of prior art, the utility model provides difference in height space that portable terminal utilizes loudspeaker and element as expansion sound chamber, has increased the sound cavity volume of loudspeaker, has promoted the audio of loudspeaker.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1 to Fig. 3, wherein, Fig. 1 is the perspective view of the portable terminal of the utility model one preferred embodiment, and Fig. 2 is the internal structure schematic diagram of the portable terminal shown in Fig. 1, and Fig. 3 is Fig. 2 structural representation that explodes.
As shown in Figure 1 to Figure 3, the utility model provides a kind of portable terminal 10, and these portable terminal 10 inside comprise first housing 110 and circuit board 120.
Wherein, circuit board 120 is located in first housing 110, and circuit board 120 is provided with loudspeaker 121 and short in the element 122 of loudspeaker 121, this element 122 can be radome or connector etc., certainly, also be provided with the element that is higher than loudspeaker 121 on the circuit board 120, as camera, motor etc.
The utility model utilizes the difference in height space of loudspeaker 121 and element 122 as expansion sound chamber.
Particularly, first housing 110 comprises the first sound chamber 111 and the second sound chamber 112.
Wherein, loudspeaker 121 are accommodated in the first sound chamber 111, and by forming sealing between foam 123 and the circuit board 120.
Wherein, foam 123 can be bonded between the first sound chamber 111 and the circuit board 120 by gum, and cover plate 124 can be bonded on the second sound chamber 112 by gum.
To sum up, those skilled in the art hold understanding, and the utility model provides difference in height space that portable terminal utilizes loudspeaker 121 and element 122 as expansion sound chamber, has increased the sound cavity volume of loudspeaker 121, has promoted the audio of loudspeaker 121.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
