Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Referring to Fig.1, the structural block diagram of one of embodiment of the present invention screen sounding device is shown.Described device packet
It includes:
At least one temperature detecting module (102/103), vibration module 104, vibratory drive module 109, control module
108, screen 101；
The vibration module 104 and at least one described temperature detecting module (102/103) are bonded with the screen 101；
Wherein, the distance between the vibration module 104 and any one of temperature detecting module (102/103) be no more than it is default away from
From；The temperature detecting module (102/103) is used to detect the temperature value of the screen 101；
The control module 108 is connect by the vibratory drive module 109 with the vibration module 104；
The control module 108 is also connect at least one described temperature detecting module (102/103)；
The control module 108 is used for, and in the case where the vibration module 104 work, obtains the temperature detection mould
The temperature value that block (102/103) detects；And according to the temperature value, determine the input to the vibratory drive module 109
Power, so that the vibratory drive module 109 drives the vibration module 104 to vibrate according to the input power.
It should be noted that inventor passes through a large amount of experiment and research, why discovery will vibrate mould in the prior art
Block is arranged on center, is because can give out a large amount of heat when vibration module vibrates, and screen usually has strictly heat
It is required that screen may be damaged more than display unit after certain temperature, such as phenomena such as flower screen or stain occur, so
Vibration module cannot be directly attached on screen in the prior art, lead to that preferable vibrating effect cannot be generated.Based on above-mentioned
It was found that it is contemplated that the embodiment of the present invention it is above-mentioned vibration module can be bonded on the screen, screen that sounding effect is good
Curtain sounding device.
