Voice coil loudspeaker voice coil is constituted with dust cap.Voice coil loudspeaker voice coil is positioned and secured in the middle of the magnetic gap of magnetic circuit system by vibrating diaphragm and centring disk, operationally,
The voice coil loudspeaker voice coil of electric signal is received to be driven diaphragm oscillations by magneticaction and promote air and then realize electric energy magnetic energy to acoustic energy
Conversion.It can be seen that vibrating diaphragm is most important for loudspeaker.
In existing senior loudspeaker, such as application such as aluminium, titanium, beryllium, ceramics, carbon fiber braiding of some new diaphragm materials is more next
Wider, the high plasticity simultaneously of these elasticity modulus of materials is good, can be made thin very light, but internally-damped deficiency, medium-high frequency
Diaphagras is easily produced during vibration and the flatness of harmful harmonic vibration influence frequency response curve makes tonequality degenerate.It is existing
Ring is single line strip (cross section angle), with vibrating diaphragm it is glued after, in junction also because different material characteristics are also easy to produce greatly point
Cut and vibrate and producing intermediate frequency paddy problem makes tonequality degenerate.
Utility model content
For the drawbacks described above and problem that loudspeaker frequency response curve traditional in the prior art is uneven, tonequality is bad, sheet
The purpose of utility model embodiment is to provide integral type compound loudspeaker vibrating diaphragm, effectively suppresses to exist in these new material vibrating diaphragms
Different type diaphagras and unwanted harmonics vibrate, improve frequency response curve flatness and after prolong transient response and then
Lift tonequality.
In order to achieve the above object, the utility model embodiment provides following technical scheme：
Integral type compound loudspeaker vibrating diaphragm, is made up of ring, Damping material layer, vibrating diaphragm layer, wherein：
Damping material layer, vibrating diaphragm layer are combined with each other, and external margin is surrounded with the material of ring, Damping material layer and ring
It is identical and be integrally formed；
The Damping material layer, vibrating diaphragm layer are combined with each other as inverted cone, raised spherical arc body or circle
Covered with Damping material layer in plane, and the outer surface of vibrating diaphragm layer.
In above-mentioned technical proposal, the section shape of the ring be raise up hemisphere face arc, half to lower recess
Sphere arc, " V " font, plane, or each bending place of inverted " W " shape and " W " shape is arc.
As the preferred of above-mentioned technical proposal, the material of the ring is rubber, fabric, foam and or PU materials group
Close.
As the preferred of above-mentioned technical proposal, the material of the vibrating diaphragm layer is aluminium, titanium, beryllium, ceramics, the list of carbon fiber braiding
Layer material.
Compared with prior art, the beneficial effects of the utility model are：
It is combined one layer of damping material again on the basis of vibrating diaphragm, and the damping layer is connected as a single entity with ring, compensate for novel-section
Expect the internally-damped not enough, vibrating diaphragm of vibrating diaphragm and the skimble-scamble shortcoming of ring junction Thickness Strength, effectively reduce vibrating diaphragm in middle height
Diaphagras and unwanted harmonics during frequency vibration, improve the flatness lifting medium-high frequency tonequality of frequency response curve；Improve simultaneously
After prolong transient response, improve low frequency tonequality.
