example 1

[0156] In this example, if Figure 6 As shown, the above-mentioned first magnet 21 is a coil 211 , and the second magnet 22 is a main magnet 2210 .

[0157] In this case, the coil 211 is disposed on the back of the display module 10 , and the main magnet 2210 is disposed on the middle frame 11 .

[0158] or, Figure 7 As shown, the above-mentioned first magnet 21 is the main magnet 2210 , and the second magnet is the coil 211 .

[0159] In this case, the above-mentioned main magnet 2210 is disposed on the back of the display module 10 , and the coil 211 is disposed on the middle frame 11 .

[0160] Also, in this example, a part of the main magnet 2210 is embedded in a closed area where the wires of the coil 211 are wound.

[0161] In order to make the second magnet 22 (for example Figure 6 main magnet 2210 as shown, or Figure 7 The illustrated coil 211 ) can be disposed on the middle frame 11 .

[0162] In some embodiments of the present application, such as Figure 6...

example 2

[0194] In this example, if Figure 10 As shown, the above-mentioned first magnet 21 is a coil 211 , and the second magnet 22 is a main magnet 2210 .

[0195] A part of the main magnet 2210 is embedded in the closed area where the wire of the coil 211 is wound.

[0196] In addition, the difference from Example 1 is that if Figure 10 As shown, the vibrator 201 further includes at least one auxiliary magnet 2211 located around the main magnet 2210 .

[0197] The auxiliary magnet 2211 is located on the same side as the main magnet 2210 . In this case, if Figure 10 As shown, when the main magnet 2210 is arranged on the middle frame 11 through the bracket 223 , the auxiliary magnet 2211 is also arranged on the middle frame 11 . Alternatively, when the main magnet 2210 is disposed on the back of the display module 10 through the support piece 212 , the auxiliary magnet 2211 is also disposed on the back of the display module 10 .

[0198] In addition, there is a gap between the...

example 3

[0206] In this example, if Figure 13 As shown, the above-mentioned first magnet 21 is a coil 211 , and the second magnet 22 is a main magnet 2210 .

[0207] In this case, the coil 211 may be disposed on the back of the display module 10 , and the main magnet 2210 may be disposed on the middle frame 11 .

[0208] or, as in Figure 14 As shown, the above-mentioned first magnet 21 is the main magnet 2210 , and the second magnet 22 is the coil 211 .

[0209] In this case, the above-mentioned main magnet 2210 may be disposed on the back of the display module 10 , and the coil 211 may be disposed on the middle frame 11 .

[0210] In this example, the top view structure of the coil 211 can be adopted Figure 11 Or the annular structure shown in 12.

[0211] In addition, the difference from Example 1 is that the main magnet 2210 is located outside the closed area formed by the wires of the coil 211 . The opposing surfaces of the main magnet 2210 and the coil 211 are parallel.

Abstract

The invention provides a mobile terminal. The mobile terminal comprises a middle frame, and a shell and a display module which are arranged on two sides of the middle frame, the display module is connected with the middle frame, and an accommodating space is formed between the display module and the middle frame; the mobile terminal further comprises a first magnet and a second magnet, and at least one part of the first magnet and at least one part of the second magnet are arranged in the containing space. The first magnet is arranged on the back face of the display module, the second magnet is arranged on the middle frame, and the first magnet and the second magnet are oppositely arranged. Wherein the first magnet is a coil, and the second magnet is a main magnet; or the first magnet is amain magnet, and the second magnet is a coil; the main magnet is a Halbach array, and a unilateral magnetic field is generated on the side, opposite to the coil, of the main magnet. According to thetechnical scheme, when the mobile terminal adopts the screen to produce sound, relatively large sound is produced through screen vibration, so that the screen sound production effect is improved.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular, to a mobile terminal. Background technique [0002] With the development of mobile terminal technology, in order to obtain a larger screen-to-body ratio, more and more mobile terminals cancel the sound output hole provided on the front of the screen, and use the screen sound technology to transmit sound. [0003] The principle of screen sound technology is to drive the screen through the vibration and sound module inside the mobile terminal, use the screen as a vibrating body, and use the screen vibration to generate sound waves that are transmitted to the human ear, so that the mobile terminal can cancel the earpiece design. [0004] Existing screen sound solutions generally have the problem of insufficient thrust of the vibration sound module, resulting in low screen sound and poor screen sound effects. Contents of the invention [0005] The present application...
