Application in refer to the inward flange of outer membrane.
As it is shown in figure 1, there is loudspeaker assembly base 11 according to the nested type compound loudspeaker of the present invention, raise one's voice
Device unitized substructure 11 accommodates the functional part of speaker and is connected to speaker housings (not shown).In short
It, unitized substructure 11 and supplementary structure element thereof accommodate the high frequency driver 8 being nested in Low frequency drivers 18,
Thus the barrier film 7 of high frequency driver 8 be positioned at Low frequency drivers 18 barrier film 4 outer peripheral after.
Loudspeaker assembly base 11 accommodates supplementary structure element, and described supplementary structure element is for providing required sound
The multiple function element replicated provide rigid body.These structural details include magnetic circuit yoke plate (magnetic
Circuit yoke plate) 14, it is attached in the rear flange of loudspeaker assembly base 11.Magnetic circuit yoke plate
14 have opening in centre, and pole shoe 10 has been fitted in this opening, and pole shoe 10 has hole 16 in centre,
Hole 16 extends through whole pole shoe.Shoulder, magnetic circuit backboard (magnetic circuit is had in the rear end of pole shoe 10
Back plate) 15 it is assembled on shoulder.Magnetic circuit backboard 15 and yoke plate 14 are served as reasons together with pole shoe 10 with holes
The magnetic field that permanent magnet 13 produces provides required magnetic structure, and permanent magnet 13 is assemblied in magnetic circuit yoke plate 14 and backboard
Between 15.
As in figure 2 it is shown, supplementary structure element also includes that high frequency driver installs adapter 12, high frequency driver is pacified
Adapter cartridge 12 is attached to the front end of pole shoe 10 from rear end.High frequency driver installs adapter 12 from front end
Being attached on high frequency adapter 2, high frequency adapter 2 accommodates high frequency driver 8.High frequency driver 8 includes height
Frequently driver diaphragm 7, the second sound coil windings is attached to the outward flange of high frequency driver barrier film 7 with the most embedding
The second permanent magnet 21 being enclosed within high frequency adapter 2 interacts.
The function element of speaker includes Low frequency drivers 18 and high frequency driver 8 and permanent magnet 13.Low frequency
Driver 18 includes barrier film 4, and barrier film 4 is attached to set of speakers from exterior slots by elastomeric outer suspension 5
Part base 11.Suspension 5 is made up of elastic lossy material (such as plastic, rubber).Rubber 5 is advantageously fabricated as
The most smooth, damage the unnecessary high portion of the frequency response of loudspeaker or discontinuous to avoid causing diffraction
Portion.It is said that in general, outer membrane 4 required skew yardstick is the least, the profile of the external suspension frame of generation is the least.This
Outward, dissipation factor is preferably selected so that the bending wave advanced on barrier film 4 terminates in suspension 5.
According to the first embodiment of the present invention, the inward flange of barrier film 4 has Low frequency drivers adapter 1, low
Frequently driver adapter 1 is also connected to sound coil frame 6.At Low frequency drivers adapter 1 and high frequency driver
There is gap 3 between adapter 2, thus allow Low frequency drivers adapter 1 together with sound coil winding 9 one
Rise and experience sound generation skew relative to high frequency driver adapter 2.Saying in a broad sense, gap 3 represents high frequency
Driver adapter 2 and around its element (that is, in the application that need not Low frequency drivers adapter 1,
Described element can also be the inward flange of barrier film 4) between the space that stays.
The front surface of high frequency driver adapter 2 and Low frequency drivers adapter 1 and barrier film 4 is tangent, thus
The sound launched from high frequency driver 8 can be advanced in the case of not reflected by the obstacle described surface.By
It is suitable for together with sound coil winding 9, bobbin 6 and barrier film 4 moving in Low frequency drivers adapter 1,
Thus be advantageously made up of solid light material (such as, plastics, aluminum or magnesium), in order to make sound coil 6
The moving mass increased minimizes.This has the impact of improvement to the response of driver.Sound coil frame 6 will
Low frequency drivers adapter 1 is connected to sound coil winding 9, and sound coil winding 9 is positioned at magnetic circuit yoke plate 14 He
In space between pole shoe 10.Aforementioned interspace between magnetic circuit yoke plate 14 and pole shoe 10 is sound coil winding 9
Move forward and backward when providing unimpeded away from (clear headway).Thus, it is conducted to sound line at alternating current
During circle winding 9, the magnetic field of sensing makes sound coil winding 9 together with the magnetic field prevailing that permanent magnet 13 produces
Forwardly and rearwardly offset.This moves and is transferred to barrier film 4 via sound coil frame 6, and barrier film 4 is suitable for axially
Change position.This moves and can be transferred to barrier film 4 directly or through Low frequency drivers adapter 1.Drive at high frequency
There is similar phenomenon, wherein, its driving means 19 (including permanent magnet and sound coil windings) in dynamic device 18
By Mobile Transmission axially back and forth to barrier film 7.
During sound coil frame 6 is supported by sound coil compliance suspension 17 (commonly referred to tripod) and is determined.Sound
Sound coil compliance suspension 17 is attached to the side of sound coil frame 6 and is attached to support from the other end from one end
Bar.On the front side of the rear flange that support bar is fixed to loudspeaker assembly base 11.Sound coil compliance suspension 17
Including two the coaxial rings connected by the sheet material with annular ripple.It supports sound coil winding 9, sound line
Coil 6 and barrier film 4, thus described mechanism keep with magnetic circuit 10,13,14,15 the most concentric, and thus sound
Sound coil windings 9 does not contacts with the parts 14,10 around its space that can be movable within.Due to barrier film 4
Supported well by sound coil compliance suspension 17, thus it can stand big axial dipole field and thus notable
Low frequency.Owing to Low frequency drivers can replicate low frequency, cross point can as little as 800Hz to 5kHz.At this
Aspect, is considered low frequency less than all frequencies in cross point, and will be considered to high frequency higher than its frequency.
As it is shown on figure 3, according to the first embodiment of the present invention, Low frequency drivers adapter 1 and high frequency driver
The gap 3 that adapter 2 is arranged so that between adapter is not circular but polygon.Along with Low frequency drivers
Adapter 1 and actually barrier film 4 be caused and move relative to high frequency driver adapter 2, raises and declines
Low frequency drivers adapter 1 causes discontinuously on the front surface of combo drive.If gap 3 has circle
Shape, then the sound forward produced in each radial direction by high frequency driver 8 will arrive the most simultaneously described in not
Place continuously.This will cause significantly weakening in the frequency response of speaker, thus damages it the most neutrally
Replicate the ability of sound.
In order to overcome, the consistent radial distance r's of the discontinuous place acoustic centres away from high frequency driver 8 is unfavorable,
The outward flange 20 of gap 3 is made with different distance r around driver 8, thus is such as shaped as polygon.Fig. 3
Shown polygon has eight angles, thus every an angle be about 180 degree, and every an angle be about
90 degree.Precisely, every an angle more than 180 degree, and every an angle less than 90 degree.
Polygon can also have difformity.Can be tetragon, triangle or even have starlike,
As shown in Figure 9.Under any circumstance, it is critical that the fewest sound forward arrive simultaneously described discontinuously
Portion.Tube shape is not how, and Low frequency drivers adapter 1 and high frequency driver adapter 2 must have correspondence
Shape, it means that sound coil frame 6 may also must be consistent with this shape in its front end.Such as, if shape
Shape is starlike, and sound coil frame 6 will have starlike shape and have in rear end round-shaped, such as Figure 10 in front end
Shown in.Thus, starlike sound coil frame 6 would be attached on the inward flange of star Low frequency drivers adapter 1.
Alternatively, as shown in Fig. 9 and 12, sound coil frame 6 can be as one man circular, and wherein, it will be attached
On the rear surface of low frequency barrier film 4 or driver adapter 1, this rear surface can be starlike shape.In a word,
The different settings for sound coil frame 6 being attached to outer membrane 4 are elaborated in Figure 11 is to 13.
As shown in Figs. 4-6, according to the second embodiment of the present invention, in each radial direction α away from high-frequency drive
The discontinuous principle of front surface making speaker at each distance r of the acoustic centres of device 8 can also be passed through will
Two drivers 8,18 arrange prejudicially and perform.Advantageously manifest unsymmetry along vertical axis, wherein erect
Straight axis has less audition impact than along horizontal axis.Accordingly, there are symmetrical horizontal acoustics to propagate, simultaneously
Due to the most small skew, the most eccentric sound source only causes border distortion.
Compared with first embodiment, the second embodiment introduces the asymmetric high frequency slightly offset along vertical axis and drives
Dynamic device adapter 2.Can also slightly offset along horizontal axis, but will not result in similar for above-mentioned reasons
Significantly result.In not sharing due to high frequency driver adapter 2 and remaining structure (such as, pole shoe bore 16)
Mandrel line, thus, the front surface of adapter 2 each direction α not with around barrier film 4 tangent, such as basis
The situation of first embodiment is such.But, described surface (is erected at least one direction α in this concrete example
Tangent the most in downward direction).Another difference is that Low frequency drivers adapter 1 not directly requirement.This be because of
For high frequency driver adapter 2, not there is the polygonal shape that neighbouring barrier film 4 will must be appropriate for.Thus, adaptive
Device 2 can have round-shaped at outer periphery, thus be allowed to unnecessary and be equipped with low to the inward flange of low frequency barrier film 4
Frequently driver adapter 1.In this case, sound coil frame 6 is directly connected to the rear surface of barrier film 4
Or inward flange.
As shown in FIG. 7 and 8, it is critical that, the acoustic centres axis of high frequency driver 8 and by Low frequency drivers
Distance r between the discontinuous portion 20 that the axial dipole field that the innermost edge of 18 produces causes is in different radial direction
α is different.From Fig. 7 it will be apparent that the offset of vertical of high frequency driver 8 makes α, r curve fluctuate, thus
Curve is not that level, i.e. distance r persistently change according to the function of radial direction α of high frequency driver 8.
Thus, the curve shown in Fig. 7 and 8 is considered as such function: distance r is the radial direction of high frequency driver 8
The function of direction α.Depending on the shape at the function edge of Low frequency drivers, α, r curve can be obeyed various
Different functions.Function can be continuous or discontinuous；Have one or more cycle periodic,
Acyclic or the most random.
From Fig. 8 it will be apparent that despite sawtooth curve, but the polygonal shape in gap 3 provides similar
Effect.But, at center equidistance r of high frequency driver 8, there are certainly multiple point, but logical
Cross the most less sound forward of this mode as in conventional application, arrive discontinuous place simultaneously.
As discussed, in different radial direction α, the variability of distance r is crucial.The shortest (rmin) and the longest
(rmax) distance (r) between difference be typically 5%-20%, be advantageously 10%-15%.This scope is also
Can be bigger, but optimum obtains by the difference of about 15%.Under any circumstance, with conventionally fabricated public affairs
Difference (generally in the range of 0.5 to 1mm or about 1% to 2%) is compared, and difference has different sizes
Magnitude.It should be noted that, in order to realize desired effects, the difference of distance r is deliberately made perceptible,
That is, the natural difference caused due to manufacturing tolerance is excluded, in order to eliminate deficiently by the one of internal sound source
Cause the weakening discontinuously caused of distance.Additionally, difference disclosed herein can be combined in the scope of the present invention
Feature has the compound loudspeaker in radially irregular discontinuous portion to produce.Raise one's voice for example, it is possible to structure is compound
Utensil has starlike shape clearance 3 and has the high frequency driver 8 of offset of vertical.Skilled artisan also recognize that
Other combination is feasible.
