The present invention provides a kind of Self-sounding module and electronic equipment, to make the purpose of the present invention, technical scheme and effect more
Add clear, clear and definite, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.It is it should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
Below in conjunction with the accompanying drawings, by the description to embodiment, the content of the invention is described further.
A kind of Self-sounding module is present embodiments provided, as shown in Figure 1,2 and 3, it includes：It include display unit 1 with
And sound-producing device, the sound-producing device are arranged on the display unit 1, and display unit 1 is driven to vibrate make it that display is single
First sounding.The sound-producing device includes rigid connector 2 and vibrator 3, the side of rigid connector 2 and display unit 1
It is connected, opposite side is connected with the vibrator 3, i.e., described rigid connector 2 connects the display unit 1 and the vibration
Device 3, and the vibration of the vibrator 2 is transferred to the display unit 1, to drive the display unit 1 to vibrate so that
The sounding of display unit 1.The present embodiment connects the vibrator and display unit by using rigid connector, it is possible to reduce
The energy loss during display unit is transferred to by vibrator is vibrated, thereby may be ensured that the sound that display unit is sent
Tonequality and loudness.
Further, the vibrator 1 is preferably piezoelectric vibrator, and the shape of the piezoelectric vibrator and number can be with
Different settings is carried out according to the difference of the electronic equipment of Self-sounding module application.For example, piezoelectric vibrator for it is circular,
Square and polygon etc., the number of piezoelectric vibrator is 1,2,3 etc..
In the present embodiment, as shown in figure 1, the number of the vibrator 1 is 1, it is shaped as circle.The vibrator
3 are arranged at the center of the display unit, and its direction of vibration is perpendicular to the display unit, to cause sound from institute
The center for stating display unit is sent.Certainly, the vibrator can also set the other positions with display unit, such as show
Base, top margin or side of unit etc..
In a variant embodiment of the present embodiment, the number of the vibrator is 2, and it is shaped as square.It is described
Two vibrators are symmetricly set on the display unit, and the line at two vibrator centers is the symmetry axis so that two
Individual vibrator vibrates to the symmetrical position of display unit, can so enable a user to listen to and arrive real stereophone
