Description
[technical field]
The utility model relates to a kind of acoustical generator, specifically refers to a kind of screen acoustical generator that is applied in the intelligent mobile device.
[background technology]
Along with the arrival in mobile Internet epoch, the quantity of intelligent mobile device constantly rises and progressively develops towards slimming and large-screen.The intelligence mobile device requires to have high-quality sound-playing function usually, and acoustical generator is one of essential condition that realizes this high-quality music function.Traditional mobile device adopts the minisize electromagnetic loud speaker to realize music playback function, but this kind constructed products more complicated and limited the slimming development of mobile phone.The appearance of screen acoustical generator provides extra selection for manufacturer and consumer.Thereby the driving screen vibration that the screen acoustical generator generally includes screen, be positioned at the screen below makes the driver of screen sounding and the toroidal support that connects screen and driver.The existence one of strutting piece can be for screen provides restoring force, and two can guarantee the sealing of cavity, and therefore the acoustic efficiency to screen generator has very big influence.Usually, we wish to improve the sound pressure sensitivity of screen acoustical generator under certain specific frequency, can reduce by first resonance frequency of screen acoustical generator simultaneously.
Therefore, be necessary to provide a kind of novel screen acoustical generator to solve the problems referred to above.
[utility model content]
The purpose of this utility model is to provide a kind of screen acoustical generator simple in structure.
A kind of screen acoustical generator, it comprises screen, drives the driver and the strutting piece that is connected described screen and driver respectively of screen vibration, it is characterized in that: described strutting piece comprises the upper surface that links to each other with screen, with described upper surface opposing lower surface, be connected the sidewall of upper and lower surface respectively, and described strutting piece is provided with the hollow bulb of excavating the part material.
Preferably, described hollow bulb is that the downward surface direction depression of upper surface forms.
Preferably, described hollow bulb is the through hole that runs through upper and lower surface.
Preferably, described sidewall comprises inner surface and outer surface on the other side, and described hollow bulb connects described inner surface.
Preferably, described strutting piece comprise two major axis limits, with vertical two minor axis limits and the fillet that is connected described major axis limit and minor axis limit, described major axis limit.
Preferably, described hollow part is on the major axis limit.
Preferably, described hollow bulb comprises first hollow bulb that is positioned on the major axis limit and second hollow bulb that is positioned on the minor axis limit.
Preferably, described hollow bulb is arranged at the position of amplitude maximum under the mode of oscillation of correlated frequency.
The beneficial effects of the utility model are: the strutting piece of the utility model screen acoustical generator is provided with the hollow bulb of excavating the part material, can reduce the rigidity of strutting piece, improves sensitivity, thereby improves the acoustical behavior of screen acoustical generator.

Fig. 1 is the exploded view of the utility model screen acoustical generator;
Fig. 2 is the schematic diagram of the strutting piece of the utility model screen acoustical generator.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, be screen acoustical generator 100 of the present utility model, thereby it comprises screen 1, drives the strutting piece 12 that screen 11 vibrations make the driver 13 of screen 11 sounding and connect described screen 11 and driver 13 respectively.Described screen can also can be the outside screen that has vocal function respectively and the double-deck screen with inboard screen of Presentation Function for the screen of individual layer, and in the present embodiment, described screen is that display screen and sounding screen are the individual layer screen of one.Described driver 13 can be in piezoelectric actuator, moving-coil type driver and the moving-magnetic type driver a kind of.
As shown in Figure 2, described strutting piece 12 is made by elastomeric material, as silicon rubber, foam etc.Described strutting piece 12 can guarantee the sealing of internal cavity when certain restoring force is provided for screen.Described strutting piece 12 comprises the upper surface 121 that links to each other with screen, the lower surface (not label) and the sidewall that be connected described upper surface and lower surface (not label) that with driver link to each other relative with described upper surface 121.Described sidewall comprise the inner surface 126 that is positioned at screen acoustical generator inside and with described inner surface 126 opposed outer surface 127.Described strutting piece 12 comprises two major axis limits 123, with vertical two minor axis limits 124, described major axis limit 123 be connected the fillet 125 of described major axis limit 123 with minor axis limit 124.
Described strutting piece 12 is provided with the hollow bulb 122 of excavating the part material.Described hollow bulb 122 is the through hole that runs through upper and lower surface and be through to described inner surface 126.Described hollow bulb 122 is positioned at the position of amplitude maximum under the mode of oscillation of correlated frequency.Mode of oscillation is the natural vibration characteristic of structure, and common described screen has different mode of oscillations under different frequency.Because the product difference of using, the correlated frequency of the required concern of different screen acoustical generator are also different.Usually being applied to the correlated frequency that the screen acoustical generator on the electronic product need pay close attention to is middle and high frequency.The position of amplitude maximum can obtain by the limited element analysis technique of prior art under the correlated frequency.As shown in Figure 2, described hollow bulb 122 comprises first hollow bulb 1221 and second hollow bulb 1222 that is positioned on the minor axis limit 124 that is positioned on the major axis limit 123.Described hollow bulb 122 is symmetrical structure.
By hollow bulb is being set, excavate the part material, can effectively reduce the rigidity at this place, thereby improve the sound pressure sensitivity under correlated frequency, reach better acoustical behavior.In addition, hollow bulb and upper surface connect as described, also can reduce the contact area of screen and strutting piece, thereby reduce by first resonance frequency.Need to prove, described hollow bulb is not limited only to said structure, can be for the through hole that connects upper and lower surface, only connect the slotted eye of upper surface or have the decorative pattern of certain depth, so long as excavate a part of material, reduced rigidity, having reduced the contact area of upper surface and screen, namely is to reach the purpose of this utility model.In addition, if do not pursue the purpose that reduces by first resonance frequency, described hollow bulb can not connect with any one surface yet, only excavates material in strutting piece inside, forms hollow structure, is to reach the purpose that improves sound pressure sensitivity yet.
Certainly, more than only be more excellent execution mode, in the enforcement, the distribution of hollow bulb can be at random and be not limited in this, can only be positioned on the major axis limit, also can be positioned on the minor axis limit, even be positioned on the fillet, also be can reach to reduce by first resonance frequency, improve the purpose of sensitivity.
The strutting piece of the utility model screen acoustical generator is provided with the hollow bulb of excavating the part material, can reduce the rigidity of strutting piece, improves sensitivity, thereby improves the acoustical behavior of screen acoustical generator.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, 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.
