Abstract
The utility model provides a mobile terminal. The mobile terminal comprises a shell, a main board arranged inside the shell and a loudspeaker connected with the main board. The mobile terminal further comprises expandable sound cavities; an opening is formed on two side walls of the shell respectively; the positions of the sound cavities are matched with the positions of the openings, such that the sound cavities can protrude out from the shell through the openings in utilization; each sound cavity comprises an expandable side wall, a top wall which is matched with the opening, and an expandable supporting rod used for supporting the sound cavity in usage; the supporting rod is arranged inside the sound cavity; and one end of the supporting rod is fixed inside the mobile terminal, and the other end of the supporting rod is fixed on the inner surface of the top wall of the sound cavity. By means of the above technical schemes, the miniaturization of the mobile terminal can be ensured, and at the same time, large enough sound cavities can be provided, such that a sound effect can be ensured.
Description
Technical field
The utility model relates to electronic technology field, relates in particular to a kind of portable terminal.
Background technology
Along with the development of electronic technology, the development trend of portable terminal is miniaturization and multifunction, and increasing user wishes that portable terminal can provide better sound effect to realize the function of music phone.As everyone knows, want to allow loudspeaker realize that better effect needs enough large resonator, and this point exactly run in the opposite direction with the requirement of portable terminal miniaturization.Therefore how can either satisfy the portable terminal miniaturization can provide again better tonequality to become the focus that industry is paid close attention to.
Summary of the invention
For the defective that exists in the prior art and deficiency, the purpose of this utility model is to propose a kind ofly can to satisfy the miniaturization requirement greatly resonator can be provided again enough, and portable terminal simple in structure.
In order to achieve the above object, the utility model proposes a kind of portable terminal, comprise shell, be arranged at the mainboard in the described shell, the loudspeaker of the described mainboard of connection; Also comprise with telescopic sound chamber; Be respectively equipped with opening on two sidewalls of wherein said shell, the position in described sound chamber and described opening are suitable so that described shell is stretched out from described opening in use in described sound chamber; Wherein said sound chamber comprise telescopic sidewall and with the suitable roof of described opening, also comprise for the telescopic support bar that supports in use described sound chamber; Described support bar is arranged in the described sound chamber, and an end is fixed in the described portable terminal, and the other end is fixed on the roof inner surface in described sound chamber.
Preferred as technique scheme, the sidewall in described sound chamber and be bow font telescopic extension.
The beneficial effect of the technical scheme that the utility model embodiment provides is: such scheme can be when guaranteeing the portable terminal miniaturization, can provide enough again large sound chamber with the assurance sound effect.
Description of drawings
Fig. 1 is the structural representation of the portable terminal of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment one is described further.
The utility model embodiment has proposed a kind of portable terminal, comprises shell 1, is arranged at the mainboard in the described shell 1, the loudspeaker of the described mainboard of connection; Also comprise with telescopic sound chamber 2.As shown in Figure 1, be respectively equipped with opening on two sidewalls of wherein said shell 1, the position in described sound chamber 2 and described opening are suitable so that described shell 1 is stretched out from described opening in use in described sound chamber 2.As shown in Figure 1, wherein said sound chamber comprise telescopic sidewall 21 and with the suitable roof 22 of described opening, also comprise for the telescopic support bar that supports in use described sound chamber; Described support bar is arranged in the described sound chamber, and an end is fixed in the described portable terminal, and the other end is fixed on the roof inner surface in described sound chamber.Wherein, the sidewall 21 in described sound chamber 2 is bow font telescopic extension.
Certainly; the utility model also can have other embodiment; in the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of claim of the present utility model.
