Embodiment 1

[0031] figure 2 A schematic structural diagram of a display device provided by an embodiment of the present invention, the device includes a screen 20 and a first exciter 21 and a second exciter 22 installed on the same surface of the screen 20, and also includes: a separate exciter 24 ;

[0032] The separate exciter 24 is installed on the screen 20, and the installation plane is the same as the first exciter 21 and the second exciter 22, wherein the separate exciter 24 is installed on the first exciter 21 and the second exciter 22 are used to offset the crosstalk vibration between the first exciter 21 and the second exciter 22 at the installation position of the separate exciter 24 .

[0033] The display device generally needs to be installed on the terminal. After the display device is installed on the terminal, one side of the screen 20 faces inward, that is, facing the terminal, and the other side faces outward, that is, for the user to use. Then the first actuator 21 an...

Embodiment 2

[0040] In order to allow the separation exciter 24 to offset the crosstalk vibration of the first exciter 21 and the second exciter 22 at the installation position of the separation exciter 24 on the screen, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, the The device also includes: a controller 23;

[0041] The controller 23 is connected with the separation actuator 24, and is used to send a target excitation signal to the separation actuator 24 according to the reverse transfer function of the separation actuator 24 stored in advance, so that the separation actuator 24 vibrating according to the target excitation signal.

[0042]The controller 23 controls the vibration of the separate exciter. In order to offset the crosstalk vibration of the first exciter 21 and the second exciter 22 at the installation position of the separate exciter 24 on the screen, the first exciter 21 and the second exciter 21 are counted through a large ...

Embodiment 3

[0046] In order to effectively remove the crosstalk vibration of the first exciter 21 and the second exciter 22 on the screen where the exciter 24 is installed separately, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, the display device may include There is one separating actuator 24 or at least two separating actuators 24 .

[0047] When a separate exciter 24 is included, the inverse transfer function of the separate exciter 24 is the inverse of the average transfer function of the vibrations of the first exciter 21 and the second exciter 22 at the first number of positions function obtained after.

[0048] When at least two separate exciters 24 are included, for each separate exciter 24, the inverse transfer function of the separate exciter 24 is the average vibration amplitude at the installation position of the separate exciter 24 and the first number of positions The ratio of the average vibration amplitude sum, and the prod...

Abstract

The invention discloses a display device and a terminal, which are used for solving the problem that a first exciter and a second exciter in the existing display device generate mutual crosstalk on ascreen. The display device comprises a separation exciter, wherein the separation exciter is installed on the screen, the installation plane of the separation exciter is the same as the installation plane of a first exciter and a second exciter, and the separation exciter is installed between the first exciter and the second exciter and used for counteracting crosstalk vibration of the first exciter and the second exciter at the installation position of the separation exciter, so that mutual crosstalk of the first exciter and the second exciter at the installation position during vibration iscounteracted, and the presentation effect of stereophonic sound can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a display device and a terminal. Background technique [0002] With the development of display technology, revolutionary changes have taken place in screen sound technology, and screen sound technology has become a development trend of display technology. Screen sound technology is based on the entire plane sound technology, it connects the exciter to one side of the screen, through the coupling between the exciter and the screen, the vibration of the exciter is transmitted to the screen, so that the screen vibrates accordingly, pushing the air to generate sound. Compared with traditional speakers, because the sound is emitted from the front, the sound from the screen can obtain crisper treble than traditional speakers. [0003] However, the left and right channels of traditional speakers are separated from the left and right, so there is no crosstalk between the sound ...
