[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a mobile terminal 100, which includes a housing 1, a screen 2, a speaker box 3, and a driving motor 4. The screen 2 is covered on the shell 1 and forms an accommodating space 10 together with the shell 1.

Specifically, the housing 1 includes a bottom wall 11, a side wall 12 extending from the periphery of the bottom wall 11 in a bending manner, an opening 13 penetrating the side wall 12, and a sound emitting slideway 14 extending from the bottom wall 11 and formed in the accommodating space 10.

The screen 2 is covered and supported on the side wall 12, and only a part of the structure of the screen 2 is shown in fig. 2.

The speaker box 3 is mounted in the housing space 10. Specifically, the speaker box 3 includes a lower cover 31, an upper cover 32, a sound outlet 33, a sound generating unit 34, and a damper 35.

The lower cover 31 and the upper cover 32 together enclose a box space 30.

The sound outlet 33 penetrates the upper cover 32. The sound outlet 33 is used to transmit sound to the outside. In the present embodiment, the sound outlet 33 opens toward the screen 2, thereby forming a screen-side sound emission structure.

Preferably, in the present embodiment, the sound emitting direction of the sound emitting port 33 is perpendicular to the screen 2.

The sound generating unit 34 is accommodated in the case space 30. The sounding unit 34 is used for generating sound by vibration.

The sound generating unit 34 and the upper cover 32 together form a front cavity 301, and the front cavity 301 is used for improving the high-frequency acoustic performance of the speaker box 3. The sound outlet 33 communicates the front cavity 301 with the outside to form a front sound production structure, the sound production structure enables the mobile terminal 100 to be free from the limitation of the size of a narrow gap of the whole mobile terminal, the stereo effect is improved, the problem of stereo piano sound noise produced by the narrow gap is avoided, and the overall performance is better.

The sound generating unit 34, the upper cover 32 and the lower cover 31 together enclose a rear cavity 302, and the rear cavity 302 is used for improving the low-frequency acoustic performance of the speaker box 3. The front cavity 301 and the rear cavity 302 together constitute the box space 30.

Specifically, the sound generating unit 34 includes a diaphragm 341 for generating sound by vibration. The diaphragm 341 and the upper cover 32 together form the front cavity 301; the diaphragm 341, the upper cover 32 and the lower cover 31 together enclose the rear cavity 302. The sound outlet 33 falls on the diaphragm 341 in the forward projection of the diaphragm 341 to the sound generating unit 34 along the vibration direction of the diaphragm 341. The vibration sounding of the vibrating diaphragm 341 is directly transmitted to the outside through the sound outlet 33, that is, a front sounding structure is formed, the sounding structure improves the stereo effect, and the overall performance is better.

The damping piece 35 is fixed to the damping piece 35 of the upper cover 32 in an adhering manner, and the damping piece 35 completely covers the sound outlet 33. The damping member 35 not only makes the vibration sound of the sound generating unit 34 transmitted to the outside, but also prevents foreign matter or water from directly entering the front cavity 301, which is advantageous for improving the reliability of the speaker box 3.

The driving motor 4 is installed in the accommodating space 10. In this embodiment, the driving motor 5 is a stepping motor, and has high sensitivity and good controllability.

The driving motor 4 is connected to the speaker box 3 for driving the speaker box 3 to move, and the sound outlet 33 is extended out of the accommodating space 10 or retracted into the accommodating space 10 through the opening 13. Preferably, in this embodiment, the driving motor 4 drives the speaker box 3 to move linearly, which is more beneficial to make the mobile terminal 100 compact in structure, small in size, and small in size.

That is to say, when the speaker box 3 works, the driving motor 4 drives the speaker box 3 to move and drives the sound outlet 33 to extend out of the accommodating space 10, namely, the sound outlet 33 extends out of the accommodating space 10 to realize sound production, and the sound outlet 33 faces the screen 2, so that a screen-side sound production structure is realized, a narrow slit does not need to be formed on the screen, namely, the sound outlet 33 is not limited by the narrow slit of the whole screen, and a full-screen structure is realized. Please refer to fig. 7, wherein a is a graph of the acoustic performance of the mobile terminal of the present invention, and b is a graph of the acoustic performance of the mobile terminal of the prior art. Fig. 7 shows that the acoustic performance of the mobile terminal 100 of the present invention is stable.

When the speaker box 3 does not work, the driving motor 4 drives the speaker box 3 to move and drives the sound outlet 33 to retract into the accommodating space 10, the damping member 35 can abut against the screen 2, that is, at this time, the upper cover 32 and the lower cover 31 abut against the screen 2 and the bottom wall 11 of the housing 1, respectively. The structural design can enable the loudspeaker box 3 and devices such as a camera to be fused together and realize a complete machine comprehensive screen structure.

The sound emitting slideway 14 mainly serves as a guide structure for the movement of the loudspeaker box 3, and improves the reliability of extension and retraction of the loudspeaker box. In this embodiment, the sound emitting slideway 14 and the opening 13 are arranged right, the speaker box 3 is accommodated in the sound emitting slideway 14, and the driving motor 4 drives the speaker box 3 to slide along the axial direction of the sound emitting slideway 14, so that the stability is improved.

Preferably, when the sound outlet 33 is retracted into the accommodating space 10, the sound outlet 33 is completely accommodated in the sound outlet slideway 14, and one side of the speaker box 3 close to the opening 13 is flush with the opening 13, so as to improve the overall aesthetic feeling of the appearance of the mobile terminal 100.

The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.
