Problems solved by technology

But once you switch to the left hand, the position of the human ear will be more in the C area, and because the C area is far from the A area, the loudness during the call will decrease, which will affect the call effect

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as image 3 As shown, a screen sound producing system 100 includes a screen 101 and an exciter 102 attached to the screen 101 for driving the screen 101 to produce sound. In this preferred embodiment, there are two exciters 102, which are arranged on the upper side of the screen 101 at intervals, and the number of exciters 102 can be more. In any position, there are exciters near the human ear. It is worth noting that, for space considerations, the size of the exciter should be as small as possible. Although the vibration of the exciter with a smaller size will be lower than that of the normal size, due to the increase in the number of exciters, the excitation The loss of loudness caused by the reduced size of the amplifier will be compensated accordingly.

[0022] In addition, the screen sound system 100 further includes a control device...

Abstract

The invention provides a screen sounding system which comprises a screen and exciters glued to the screen and used for driving the screen to sound. The screen sounding system further comprises a control device and a detection sensing device which is used for detecting the noise amplitude of an external environment and the positions of human ears and is electrically connected with the control device. At least two exciters are coupled to the screen, and the at least two exciters are electrically connected with the control device. According to the screen sounding system of the invention, at least two exciters are glued to the screen, and the control device decides whether the exciters work or simultaneously work according to the noise amplitude of external environment and the positions of the human ears, detected by the detection sensing device, which enables higher call loudness and higher call quality to be obtained no matter where the human ears are located.

Description

【Technical field】 [0001] The invention relates to the field of screen sound generation, in particular to a screen sound generation system and a control method thereof. 【Background technique】 [0002] Screen sound technology refers to the technology of placing the exciter behind the display screen, through the coupling of the exciter and the display screen, the vibration of the exciter is transmitted to the display screen, and the sound is emitted through the vibration of the display screen. Such as figure 1 As shown, the screen sound technology in the related art only uses an exciter 12 placed behind the display screen 11 to drive the screen to make sound. During the application of this technology, some problems will arise: [0003] For example, when encountering size constraints, the exciter 12 will compete for space with other devices, such as cameras, USB interfaces, earphone jacks, etc. At this time, the exciter 12 will be placed on the edge (such as figure 2 shown)....
