[embodiment]
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As depicted in figs. 1 and 2, mobile terminal of the present utility model, it comprises the screen sound-producing device and for the outside framework 3 of fixing described screen sound-producing device.Screen sound-producing device of the present utility model comprises for the screen 1 of vibration sounding and the drive unit 2 that drives described screen 1 vibration sounding.
Between drive unit 2 and described non-display area 11, be provided with for transmitting the drive disk assembly 4 of drive unit 2 actuating forces, described drive disk assembly 4 one ends are fixed in drive unit 2, its other end is fixed in non-display area 11, thereby power or the displacement that drive unit 2 can be produced pass to screen 1.The direction of vibration normal to screen 1 of this drive unit 2.In the present embodiment, described drive disk assembly 4 is a cylindrical piece, and certainly, in selectable other execution modes, drive disk assembly can be also other forms such as rectangular block.
As Fig. 3 to as shown in Fig. 5, outside framework 3 is for having the loop configuration of a receiving space (not label), it comprises the frame 31 of periphery and the limiting section 33 extended to receiving space from frame 31 inner surfaces, described screen 1 is overlapped on described limiting section 33, simultaneously, be connected to the inner surface of described frame 31, play the fixation of screen 1.Further, carry out the fixing of screen by modes such as gummed or screws.Certainly, its fixed form is not limited to this.
Comprise the fixed part 32 that is positioned at non-display area 11 belows on described limiting section 33, described fixed part 32 is positioned on the minor face of mobile terminal, is positioned at for the non-display area of sounding 11 times.Described fixed part 32 is provided with the accepting groove 30 connected with receiving space, and described drive unit 2 is accommodated and is fixed in described accepting groove 30.
Described drive unit 2 is piezoelectric vibrator, and it comprises sheet metal 20 and be attached at respectively the piezoelectric ceramic piece 21 of described sheet metal 20 both sides, and described sheet metal 20 slightly is longer than described piezoelectric ceramic piece 21.Certainly, this is only selectable a kind of execution mode, in fact, also can a side at sheet metal be provided with a piezoelectric ceramic piece, also can implement.Drive disk assembly 4 is attached at the surface near the piezoelectric ceramic piece 21 of screen one side, more excellent, is attached at the center on piezoelectric ceramic piece surface.Like this, the vibration that can pack drive unit is more stable, guarantees the performance of screen sounding.
Fixed part 32 is provided with the holddown groove 301 that is positioned at accepting groove 30 both sides and communicates with accepting groove 30, and the lower surface of these holddown groove 301 self-retaining sections 32 is to the depression of the direction near screen 1.The two ends of sheet metal 20 are accommodated respectively and are fixed in this holddown groove 301, have played the fixation of drive unit.Certainly, this is a preferably embodiment of the utility model, in selectable other embodiment, also can there is no holddown groove, and sheet metal extends to the accepting groove both sides and is directly fixed on fixed part, also can implement.Its fixed form can, for gummed, can be also other modes.
As shown in Figure 5, described viewing area 10 comprises glassy layer 100, display module layer (not indicating) and the touch sensitive layer between described glassy layer 100 and display module layer (not indicating), and described non-display area 11 comprises glassy layer 100.
As shown in Figure 1, described mobile terminal also comprises packing ring 5 and the bonnet 6 connect with described packing ring 5 lids.
Mobile terminal of the present utility model can be mobile phone or panel computer etc., certainly, can be also other electronic products.During mobile terminal work, after the conversation audio signal received is processed and being amplified, pass to the input of piezoelectric vibrator, piezoelectric vibrator vibrates and drives the screen vibration, the screen vibration can produce corresponding audio frequency, thereby has just realized the function as receiver.Therefore, without receiver separately is set under screen, so just can reduce the thickness of mobile terminal,, due to without receiver separately is set, also just can implement without the sound hole of offering on glass at screen simultaneously.
In addition, owing to having utilized outside framework 3 fixed drive devices 2, drive non-display area 11 vibrations, therefore without support system or suspension system are set, further reduced the thickness of mobile terminal, and performance is more stable.
Above-described is only better embodiment of the present utility model; at this, it should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
