Problems solved by technology

[0002] At present, when a display terminal, such as a mobile phone is in a handheld call, the sound from the mobile phone will leak from the gap between the auricle and the mobile phone to the back of the mobile phone during the process of entering the human ear, or part of the sound will pass through the head. Reflected to the back of the phone, causing sound leakage
In this way, when the user is talking in a relatively quiet public place (for example, in a conference room, in an elevator), the sound leakage of the mobile phone can easily leak the user's privacy, thereby reducing the user experience

example 1

[0072] In this example, if Figure 5 As shown, the first magnet assembly 31 includes a first magnet 310 and the second magnet assembly 32 includes a second magnet 320 . The third magnet assembly 33 includes a coil 330 . Wherein, the polarities of the first magnet 310 and the second magnet 320 are opposite. E.g Figure 5 Among them, the first pole (S) of the first magnet 320 and the first pole (S) of the second magnet 320 are both disposed close to the coil 330 . The second pole (N) of the first magnet 310 is disposed close to the display module 10 , and the second pole (N) of the second magnet 320 is disposed close to the casing 12 .

[0073] Alternatively, in some other embodiments, the second pole (N) of the first magnet 320 and the second pole (N) of the second magnet 320 are both disposed close to the coil 330 . The first pole (S) of the first magnet 310 is located close to the display module 10 , and the first pole (S) of the second magnet 320 is disposed close to the...

example 2

[0095] In this example, it is the same as Example 1, such as Figure 10a As shown, the first magnet assembly 31 includes a first magnetic frame 311 and a first magnet 310 disposed in a first groove 312 of the first magnetic frame 311 . The second magnet assembly 32 includes a second magnetic frame 321 and a second magnet 320 disposed in a second groove 322 of the second magnetic frame 321 . Wherein, the polarities of the first magnet 310 and the second magnet 320 are opposite. The third magnet assembly 33 includes a bracket 331 and a coil 330 disposed in a bracket slot 332 of the bracket 331 . In addition, a first through hole 120 is disposed on the supporting plate 110 of the above-mentioned middle frame 11 .

[0096] The difference from Example 1 is that, if Figure 10a As shown, at least a part of the coil 330 and the bracket 331 are disposed in the above-mentioned first through hole 120 . In this case, the groove wall of the bracket groove 332 can pass through the firs...

example 3

[0107] In this example, it is the same as Example 1 and Example 2, such as Figure 13a (along Figure 12 As shown in the cross-sectional view obtained by cutting along the dotted line E-E), the first magnet assembly 31 includes a first magnetic frame 311 and a first magnet 310 disposed in a first groove 312 of the first magnetic frame 311 . The second magnet assembly 32 includes a second magnetic frame 321 and a second magnet 320 disposed in a second groove 322 of the second magnetic frame 321 . Wherein, the polarities of the first magnet 310 and the second magnet 320 are opposite. The third magnet assembly 33 includes a bracket 331 and a coil 330 disposed in a bracket slot 332 of the bracket 331 . In addition, a first through hole 120 is disposed on the supporting plate 110 of the above-mentioned middle frame 11 .

[0108] The difference from the above example 1 and example 2 is that, if Figure 12 As shown, the third magnet assembly 33 further includes an iron core 40 di...

Abstract

The embodiment of the invention provides a display terminal, relates to the technical field of display, and is used for reducing the phenomenon of sound leakage of the display terminal in a handheld call scene. In the display terminal, a display module is connected with a middle frame, and a first containing cavity is formed between the display module and the middle frame. A shell is connected with the middle frame, and a second containing cavity is formed between the shell and the middle frame. A first magnet assembly is arranged in the first containing cavity and connected with the display module. A second magnet assembly is arranged in the second containing cavity and connected with the shell. The second magnet assembly and the first magnet assembly are oppositely arranged. A third magnet assembly is connected with the middle frame and arranged between the first magnet assembly and the second magnet assembly. In the direction perpendicular to the light emitting face of the display module, the third magnet assembly and the first magnet assembly are used for driving the display module to vibrate to generate first sound waves. The third magnet assembly and the second magnet assembly are used for driving the shell to vibrate to generate second sound waves, and the first sound waves and the second sound waves are opposite in phase.
