Problems solved by technology

However, limited by the thickness of the mobile phone, it is difficult to further increase the size of the above-mentioned vibrator along the thickness direction of the mobile phone.
This will cause the displacement of the driver to drive the screen to be small, and the volume of the screen's sound will be insufficient

example 1

[0083] In this example, the first drive assembly 22 in the above-mentioned first vibrator 20 may include, for example, Figure 4At least one first telescoping assembly 200 is shown. The first telescopic assembly 200 may include a first telescopic rod 201 , a first electrode 301 and a second electrode 302 .

[0084] The first telescopic rod 201 is in a direction parallel to the display surface of the display module 10 (for example, Figure 2a shown in the Y direction), arranged in the first fixed frame 21 . The first electrode 301 is connected to the first end of the first telescopic rod 201 and the inner surface of the first fixing frame 21 . The second electrode 302 is connected to the second end of the first telescopic rod 201 and the inner surface of the first fixing frame 21 .

[0085] In this case, the material constituting the above-mentioned first telescopic rod 201 may include an electrostrictive material, for example, a piezoelectric ceramic material. The material...

example 2

[0104] In this example, as in Example 1, the first vibrator 20 may include a first fixing frame 21 and a first driving assembly 22 disposed in the first fixing frame 21 . The difference from Example 1 is that the first drive assembly 22 includes, for example, Figure 11aThe first telescopic rod 201 , the second telescopic rod 221 , the first magnet 231 , the second magnet 232 , the third magnet 233 , the fourth magnet 234 , the first magnetic conductive rod 241 , and the second magnetic conductive rod 242 are shown. In addition, the first driving assembly 22 further includes a first coil 251 spirally surrounding the first telescopic rod 201 , and a second coil 252 spirally surrounding the second telescopic rod 221 .

[0105] like Figure 11b As shown, the first telescopic rod 201 is parallel to the display surface of the display module 10, that is, the first telescopic rod 201 is parallel to the display surface of the display module 10. Figure 11b The Y directions shown are...

example 3

[0115] In this example, as in Example 1, the first vibrator 20 may include a first fixing frame 21 and a first driving assembly 22 disposed in the first fixing frame 21 . The difference from Example 1 is that the above-mentioned first driving assembly 22 may include Figure 12a A first support rod 261 , a second support rod 262 and at least one second vibrator 40 are shown. The first end of the first support rod 261 is connected to the inner surface of the first fixing frame 21 . The first end of the second support rod 262 is connected to the inner surface of the first fixing frame 21 . The second vibrator 40 is disposed in the first fixing frame 21 and located between the first support rod 261 and the second support rod 262 . The second vibrator 40 is connected with the first support rod 261 and the second support rod 262 .

[0116] The above-mentioned second vibrator 40 may include, for example, Figure 12b The second fixed frame 41 and at least one second drive assembly...

Abstract

An embodiment of the present application provides a mobile terminal, which relates to the technical field of screen sound production, and is used to improve the problem of insufficient volume in the process of realizing screen sound production by the mobile terminal. The mobile terminal includes a middle frame, at least one first vibration. The display module is connected with the middle frame, and a accommodating cavity is formed between the display module and the middle frame. The first vibrator is arranged in the accommodating cavity. The first vibrator includes a first fixed frame and a first drive assembly. The first fixed frame is connected with the display module and the middle frame. The first driving component is disposed in the first fixing frame along the direction parallel to the display surface of the display module. Both ends of the first driving component are connected with the inner surface of the first fixing frame. The distance between the surface of the first fixing frame close to the display module and the first driving component is smaller than the length of the first driving component. The first driving component is stretched and deformed along the length direction of the first driving component, so that the first fixing frame drives the display module to vibrate up and down in a direction perpendicular to the display surface of the display module.

Description

technical field [0001] The present application relates to the technical field of screen sound generation, and in particular, to a mobile terminal. Background technique [0002] Users have higher and higher requirements on the screen ratio of mobile terminals, such as mobile phones. In order to increase the overall screen ratio of the mobile phone, a driver can be arranged on the back of the display screen of the mobile phone to drive the display screen to vibrate up and down in the direction of the thickness of the mobile phone. In this case, the display screen can be used as a diaphragm to push the air to generate sound during the vibration process, so as to realize the sound of the screen. In this way, there is no need to punch holes on the front of the mobile phone and install the earpiece, so that the purpose of increasing the screen ratio of the mobile phone can be achieved. [0003] It can be seen from the above that the driver inside the mobile phone can drive the d...
