Description
Technical field
The present invention relates to the ribbon speaker of one of dynamic loudspeaker in stereo set, belong to electroacoustic techniques field, this hair
Bright more particularly to a kind of ribbon speaker vibrating diaphragm of non-wide segmentation.
Background technology
Famous semiconductor science person Walter Schottky（Walter Schottky）With Siemens Halske（West
The sub- Ha Er Coases of door）Nineteen twenty-three has invented ribbon high pitch loudspeaker, due to can not find magnetic very strong magnet at that time, vibrating diaphragm
Impedance and power very little is born, cause inefficiency, so at that time using not extensively.Later people utilize aluminum vibrating diaphragm simultaneously
Magnetic circuit and vibrational system matching are formed with more ferromagnetic material, obtain preferable efficiency and tonequality, ribbon high pitch loudspeaker
Start gradually to popularize in high-end speakers systematic difference.
Common ribbon speaker tweeters diaphragms have several forms：
Fine aluminium vibrating diaphragm：Such as CN 98246922：Vibrating diaphragm is made of a whole aluminium foil, and such vibrating diaphragm impedance is very low, it is also necessary to one
Transformer as impedance conversion is connected with power amplifier.Since vibrating diaphragm described in stress concentration is highly susceptible to impact or because of gold
Belong to fatigue and tear；Intensity vibrating diaphragm to strengthen its width is also pressed into wave-like, and original intention is to ensure that vibrating diaphragm in width
Being synchronized with the movement on direction, but often on a specific frequency aluminium strip because various unbalance factors and be distorted deformation and then hair
Go out strong metallic sound.In addition such vibrating diaphragm keeps some tension by contraction that itself undaform embosses, but because aluminium
Resilience is poor, it is easy to which, because impact is permanently deformed, positioning accuracy of the aluminium strip in magnetic circuit is not high.
Compound vibrating diaphragm：Such as CN200420023548, conductive metal foil significantly increases vibrating diaphragm with organic film recombination energy
Intensity and increase its internal damping, but still need impedance-matching transformer.
Compound printing vibrating diaphragm as disclosed in CN201310300212, passes through quarter on the aluminium foil that organic film is base material
Etching technique produces the vibrating diaphragm with specified impedance, and such vibrating diaphragm can be directly driven by Conventional power amplifiers, it is no longer necessary to be become
Depressor carries out impedance matching.More comprehensively, only with respect to fine aluminium vibrating diaphragm, composite bed adds vibrating diaphragm to such diaphragm performance
Quality, efficiency slightly reduces, and the base material in addition manufacturing this vibrating diaphragm often accumulates certain stress in laminating production process,
The uneven of stress also results in diaphragm deformation, and the planarization of sound film is still improved space, and the stress uniformity of diaphragm is for system
It is particularly important to make even uniform of the Large size Aluminium with high pitch for example aluminium strip tweeters diaphragms that length reaches 1 meter.
Fabric strip vibrating diaphragm, such as CN200510036972, such sound film have preferably itself damping, but more than
Its production difficulty of the vibrating diaphragm of type is higher, because to be woven, it is necessary to use accurate weaving machinery to come really to fine silk of knitting
The dimensional accuracy and uniformity coefficient of sound film after weaving are protected, operation difficulty is big, and cost is higher.
It follows that existing vibrating diaphragm its because magnetic gap intrinsic inductance it is uneven, the diaphragm deformation as caused by Ampere force loses
True problem affects the use quality of vibrating diaphragm.
The content of the invention

Quality（Contain unit width line paper tinsel sole mass and the air additional mass of corresponding drive area）.
By formula（1）As long as it can know the size of current for adjusting each subdivision conducting wire paper tinsel width or each subdivision conducting wire paper tinsel（It can pass through
Each sufficient size of current of foreign current distributor circuit adjustment is realized）Or corrdinated adjustment, making formula establishment that can carve makes vibrating diaphragm in width
Spend synchronous vibration on direction.
It will be above-mentioned（1）Formula deforms to obtain：
（2）
As preferred scheme, each subdivision conducting wire paper tinsel is connected so that electric current is equal, while controls the uniform quality of vibrating diaphragm i.e.It is identical to get to：
（3）
By above-mentioned formula（3）It can obtain, control each subdivision conducting wire paper tinsel width and the average magnetic induction intensity of residing magnetic gap position proportional
Example relation, can be consistent by the Acceleration Control of vibrating diaphragm each several part on magnetic gap width, so that vibrating diaphragm is in magnetic gap
Synchronous vibration.
