Embodiment 1

[0043] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a screen sound generating device 10, figure 1 A schematic diagram of the three-dimensional structure of the screen sound generating device 10, figure 2 It is a schematic diagram of the three-dimensional structure of the screen sound device.

[0044] In the embodiment of the present invention, the screen sound generating device 10 includes a screen 11, a back cover 12, and a middle frame 13 placed between the screen 11 and the back cover 12, and the screen 11 and the back cover 12 are respectively fixed on both sides of the middle frame 13. Two cavities are formed, one cavity is the space formed between the middle frame 13 and the rear cover 12 , and the other cavity is the space formed between the middle frame 13 and the screen 11 .

[0045] The middle frame 13 is provided with an exciter 131 fixed on the screen 11. When the exciter 131 vibrates, the screen 11 which has a fixed...

Embodiment 2

[0054] The embodiment of the present invention shows each module unit and the function of each module related to the calculation of the second driving signal in the signal processor of the first embodiment above.

[0055] In the embodiment of the present invention, the signal processor may include a signal calculation module and a signal sending module, and in the embodiment of the present invention, the drive signal input to the actuator is used as the first drive signal, and the drive signal input to the vibrator is used as the second drive signal. driving signal, the functions of the signal calculation module and the signal sending module are as follows:

[0056] A signal calculation module, configured to set a second drive signal input to the vibrator according to the first drive signal input to the exciter;

[0057] a signal sending module, configured to send the second drive signal to the vibrator,

[0058] In a specific application, the relationship between the first d...

Embodiment 3

[0075] The embodiment of the present invention proposes the structure of another screen sound emitting device 20 based on the first embodiment above, including a screen 21, a rear cover 22, a middle frame 23 placed between the screen 21 and the rear cover 22, and an exciter 231 and vibrator 232.

[0076] In the embodiment of the present invention, the positional relationship between the screen 21, the back cover 22, the middle frame 23 and the exciter 231 is the same as that in the first embodiment, and will not be described in detail, but the middle frame 23 is not fixed with the exciter. The part includes a plurality of target positions 233, the vibrator 232 is placed on the target position 233, and the signal generator 234 is connected with each vibrator 232, each vibrator 232 is responsible for the modeling and control of a target position 233 respectively, each vibration The application method of the device 232 is the same as that in the first embodiment.

Abstract

The invention is applicable to the technical field of acoustic equipment, and provides screen sounding equipment and a screen sounding method. The equipment comprises a screen, a rear cover and a middle frame arranged between the screen and the rear cover, and the screen and the rear cover are respectively fixed at two sides of the middle frame to form a cavity; the middle frame is provided with an exciter fixed on the screen, the middle frame is also fixedly provided with a vibrator and a signal processor electrically connected with the vibrator, and the vibrator is arranged between the middle frame and the rear cover; and when the exciter vibrates to cause the screen to vibrate and produce sound, the signal processor processes a driving signal in the vibrator, so that the vibrator and the exciter vibrate synchronously and reversely to counteract the vibration of the middle frame and / or the rear cover. Redundant vibration caused by vibration of the rear cover can be reduced, and the comfort of holding a mobile terminal for a long time by a user is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of acoustic equipment, in particular to a screen sound generating equipment and method. 【Background technique】 [0002] Existing screen sound generating devices use an exciter to drive the structure of the device to vibrate and generate sound. The structure can be the panel of the device, the back cover, etc. When the exciter is working, it drives the screen to vibrate and make sound, and while driving the screen to vibrate, it will also give a driving force to the middle frame of the mobile terminal, causing the middle frame of the mobile terminal to vibrate, and the vibration of the middle frame is transmitted to the back cover. , will also cause relatively obvious vibration of the rear cover, therefore, the user can clearly perceive this vibration when holding the mobile terminal. [0003] However, when a user holds a mobile terminal, the vibration sense transmitted from the back cover to the user's ha...
