[utility model content]
In view of the deficiency of prior art, the main purpose of the utility model is that the bass that a kind of passive radiator is provided and has passive radiator strengthens combination, but this passive radiator is that elasticity adjustment tonequality is reinforced.This passive radiator is through the flexible variation of mass quality, but the tonequality of elasticity adjustment low-frequency range.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of passive radiator comprises framework, outstanding limit and vibrating diaphragm, is connected through said outstanding limit realization between said vibrating diaphragm and the said framework and fixes, wherein,
Said vibrating diaphragm is the high strength vibrating diaphragm, and the centre position of said vibrating diaphragm is formed with the chamber of placing mass, and the adjustable mass of quality is arranged in the inside of said chamber.
Wherein more excellently, between the outer wall of said chamber and said framework, be provided with the bullet ripple.
Wherein more excellently, said bullet ripple is that annular is wavy.
A kind of bass with passive radiator strengthens combination, comprises loud speaker and passive radiator, but wherein said passive radiator is the above-mentioned reinforced passive radiator of elasticity adjustment tonequality.
The passive radiator that the utility model provided also diminishes obvious reduction of operating frequency and distortion through the improvement to internal structure, thereby makes the low frequency performance of loud speaker better.On the other hand, through the flexible variation of mass quality, but elasticity is adjusted the operating frequency of this reinforced passive radiator, thereby further improves the tonequality of low-frequency range.

[embodiment]
For making the utility model above-mentioned purpose, characteristic and advantage more obviously understandable, hereinafter is special lifts the utility model preferred embodiment, and conjunction with figs., elaborates as follows.Moreover, the direction term that the utility model is mentioned, for example " on ", D score, " preceding ", " back ", " left side ", " right side ", " interior ", " outward ", " side " etc., only be direction with reference to annexed drawings.Therefore, the direction term of use is in order to explanation and understands the utility model, but not in order to restriction the utility model.
The utility model is the acoustics law that the vibration area is bigger, frequency is low more by sound; And the acoustics law that vibration velocity is slower, frequency is low more; Add the more little experimental result of the solid more distortion of vibrational structure; Through the architecture advances inner, let and use the loud speaker bass effect of this reinforced passive radiator better passive radiator.
For this reason, as shown in Figure 3, in the passive radiator that the utility model provided, a technical characterstic that is showing is that vibrating diaphragm 11 has used the high strength vibrating diaphragm that is difficult for deformation, the preferably, and said vibrating diaphragm 11 is high duty metal vibrating diaphragm or highstrenghtpiston's vibrating diaphragm.Realize being connected through outstanding limit 10 between this vibrating diaphragm 11 and the framework 9 and fix.But different is with the passive radiator of tradition, be formed with the chamber 13 of placing mass in the centre position of vibrating diaphragm 11, and mass 12 is placed on chamber 13 inside, and certain gap is left in the centre.In addition, also be provided with annular wavy bullet ripple 8 between the outer wall of this chamber 13 and the framework 9.
Owing to used the high strength vibrating diaphragm 11 that is difficult for deformation in this passive radiator; Chamber 13 outer walls of in addition placing mass 12 are provided with bullet ripple 8 and realize being connected with framework 9; The vibration area of therefore participating in sounding is showing and is enlarging, and the obviously more traditional passive radiator of vibrational structure is more solid.Like this, the operating frequency of this passive radiator obviously reduces and distortion also diminishes, and can let the low frequency performance of loud speaker better, and it is not enough for associated loudspeaker product bass to satisfy consumers in general, and requires to have the demand of more basses.
