Description
Technical field
It is the present invention relates to speaker technology field, in particular to a kind of using the loudspeaker in HIFI speaker with gas-tight ring
And reinforce damping method.
Background technique
As small-sized portable speaker is universal, and require small-size sound box that can issue lower low-frequency sound wave, passively
Radiator formula is designed to first choice.Current design is commonly using as shown in Fig. 1 only with the plate spoke of outstanding side support
The oscillating plate of emitter seldom with conventional loudspeakers type as shown in Fig. 2, while having the passive radiation for playing wave and the support of outstanding side
Device.And in order to extend the response of low frequency, the tuned frequency of radiator is very low, thus the quality of radiator is larger, and such one
Come, the support and control of radiator is applied alone the support of outstanding side suspension just highly difficult, the irregular movement of radiator or waves more bright
Aobvious, replaying bass effect is general.Therefore big mass radiation device only just becomes a technological difficulties with outstanding side support and control, while
It is the hot spot studied at present.
In order to improve the support and damping of radiator, wherein as shown in Fig. 3, the Litovsky of Bose company is proposed
Improve the support and damping of radiator with the scheme of supporting beam, inhibits diaphagras.According to analysis of experiments, Litovsky is found
The design of support beam type have some improvement the effect of support, but it is unsatisfactory.And the rockingmode described in it, refer to
The irregular transverse movement of radiator, rather than the diaphagras of the oscillating plate of radiator that Litovsky thinks.The reason is that spoke
Emitter is only operated at low-frequency range.Even small-size sound box, the tuned frequency of radiator is also only 300 hertz or hereinafter, and spoke
Emitter only works near tuned frequency, thus the frequency range occurred far below the diaphagras of radiator oscillating plate.It is so-called
Rockingmode " rock and roll mode ", i.e. oscillating plate are because driving force is asymmetric, gravity and outstanding side are asymmetric, the factors such as non-linear are drawn
The irregular transverse movement risen.
Equally, in order to improve the support and damping of radiator, as shown in Fig. 4, Sahyoun proposes double suspension side scheme,
When being to solve single outstanding side, the upper half elastic force different by outstanding side from lower half is non-linear when radiator moves up and down
Problem.And the scheme that Philips is proposed is as shown in Fig. 5 multiple closed gas chamber rings to provide additional air-pressure damping
Improve the damping of radiator vibration, and then improves sound quality.Although gas chamber ring or tire the formula design of Philips can provide very well
Air damping effect, but improve support technical effect there are also to be strengthened.Reason is as follows:
The ideal movements of radiator are in by speaker under the control of air pressure, in the vertical direction perpendicular to radiator plane
It moves back and forth, this is catenary motion.And influenced by the factors such as gravity and the elastic-nonlinear on outstanding side, radiator is in vertical fortune
It is dynamic to add some lateral irregular movements simultaneously namely Litovsky claims Rockingmode " rock and roll mode ", and
Sahyoun is known as wobble and " waves ".In the scheme of philips, when radiator is to side transverse shifting, this side hangs side
It is compressed, the outstanding rim portion of opposite side is stretched, and the volume of gas chamber is generally speaking without significant change, so that the indoor air pressure of gas
Do not change, and air pressure having the same in entire gas chamber, the lateral power that gas chamber air pressure applies radiator periphery is each
To the same sex, it that is to say and offset each other.That is cyclic annular tire type gas chamber hangs side, the i.e. scheme of Philips, without obvious
The gas chamber inhibiting effect to the movement of radiator lateral oscillation, namely without apparent cross-brace improvement.The side of Sayhoun
Case is also identical with this, the effect improved without the apparent gas chamber supporting damping for laterally determining core.
