In other embodiment, also available other structure realizes driving the above-mentioned drive unit 2 that resonance speaker 3 moves up and down, as by a cylinder and a connecting rod are set, connecting rod one end is fixed on cylinder, the other end is connected with resonance speaker 3, promote connecting rod by cylinder and move up and down, move up and down thereby drive resonance speaker 3, to leave or to be positioned on dielectric-slab 11.
Dielectric-slab 11 can be made for materials such as plank, plastic plate, steel plate, glass.Because resonance speaker 3 is by the resonance sounding of dielectric-slab 11, thereby the thickness of dielectric-slab 11, size, the sound that material all can be sent resonance exerts an influence, playback effect for further prominent resonances sound equipment 3, the utility model is also analysed thickness to the medium of resonance speaker showcase of the present utility model, different and the different big or small resonance speaker showcases of material are installed identical resonance speaker 3, carry out audio-frequency test, followingly according to several more typical audio frequency correlation curve figure, further illustrate, thereby produce the resonance speaker showcase that can better show resonance speaker 3 voice effects:
Refer to Figure 13, the resonance speaker showcase that the dielectric-slab of three kinds of thickness is made, audio frequency correlation curve figure when resonance speaker is worked on dielectric-slab; The size of three kinds of resonance speaker showcases is long 50cm, wide 45cm, high 20cm; Dielectric-slab is plastic plate, and resonance speaker power is 5w.Audio curve when in figure, curve B 1 is 1mm for the dielectric-slab thickness of resonance speaker showcase; Curve B 2 is the audio curve while for the dielectric-slab thickness of resonance speaker showcase, being 2mm; Curve B 3 is the audio curve while for the dielectric-slab thickness of resonance speaker showcase, being 3mm.As can be seen from Figure, in the frequency range of 100-400Hz, when dielectric-slab thickness is 2mm, the decibel that resonance speaker shows is relatively the highest; When dielectric-slab thickness is 1mm, the decibel that resonance speaker shows secondly; When dielectric-slab thickness is 3mm, the resonance speaker decibel is relatively minimum.That is to say, dielectric-slab is 2mm when thick, better, thickening or attenuation, in the performance of this frequency range, all can descend then.But, in the frequency range of 400-600Hz, when dielectric-slab thickness is 2mm, the decibel numerical fluctuations that resonance speaker shows is obvious, trough occurs; In the frequency range of 400-600Hz, when dielectric-slab thickness is 1mm, the decibel numerical fluctuations that resonance speaker shows is obvious, trough occurs, and is that the trough of 2mm when thick is narrower than dielectric-slab; And dielectric-slab thickness is while being 3mm, to making the relative decibel value of resonance speaker playback relatively mild.As seen from the figure, dielectric-slab thickness increases, and can make this resonance speaker showcase milder to the performance of resonance speaker playback.Thereby the thickness of General Requirements dielectric-slab is more preferably greater than 1mm.
Refer to Figure 14, the resonance speaker showcase that the dielectric-slab of three kinds of materials is made, audio frequency correlation curve figure when resonance speaker is worked on dielectric-slab; The size of three kinds of resonance speaker showcases is long 50cm, wide 45cm, high 20cm; Dielectric-slab is that 3mm is thick, and resonance speaker power is 5w.In figure, the dielectric-slab material of curve C 1 correspondence is plastic plate, and the dielectric-slab material of curve C 2 correspondences is plank, and the dielectric-slab material of curve C 3 correspondences is steel plate.As seen from the figure, plastic plate is relatively more easily driven resonance by resonance speaker, and secondly, and the steel plate relative difficult is driven resonance by resonance speaker to plank.The audio curve big rise and fall that plastic plate is corresponding, the audio curve that plank is corresponding with steel plate is relative mild, thereby the dielectric-slab of resonance speaker showcase is better comparatively speaking while being plank.Certainly, the zone difference of the frequency of the sound of mainly playing according to resonance speaker, also can make dielectric-slab with other material.
Refer to Figure 15, the resonance speaker showcase of three kinds of sizes, audio frequency correlation curve figure when resonance speaker is worked on its dielectric-slab; The dielectric-slab of three kinds of resonance speaker showcases is plastic plate, and thickness is 3mm, and resonance speaker power is 5w; In figure, the resonance speaker showcase of curve D 1 correspondence is of a size of long 50cm, wide 45cm, high 20cm; In figure, the resonance speaker showcase of curve D 2 correspondences is of a size of long 40cm, wide 40cm, high 20cm; In figure, the resonance speaker showcase of curve D 3 correspondences is of a size of long 30cm, wide 30cm, high 20cm.As seen from the figure, the size of resonance speaker showcase is larger, and corresponding decibel value is higher, easier driven resonance.
By above enforcement, make a resonance sound equipment showcase, itself and existing resonance speaker be placed directly on desktop and work, more easily driven, playback is better, refers to Figure 16, when in figure, curve E1 is resonance speaker work, place it in the audio curve on this resonance speaker showcase, curve E2 is the audio curve placed it on ordinary desktop; This resonance speaker power is 5W, and the resonance speaker showcase is of a size of long 50cm, wide 45cm, high 20cm; Dielectric-slab is plank.As seen from the figure, curve E1 decibel (dB) is worth in effective frequency range apparently higher than curve E2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
