According to the embodiment be shown specifically in Fig. 3, the first driver element 200 comprises the front end that cylindrical mounting 201, two drivers 210,220 are fitted to this cylindrical mounting coaxially.According to such inventive concept, driver element can comprise the driver of any amount.First driver element 200 can be configured to comprise an only driver naturally.But according to a preferred embodiment, the first driver element 200 comprises two coaxial revolvers 210,200, and the second driver element 300 comprises single driver.Within this context, term " front " and " afterwards " represent direction, and wherein " forward direction " means sound wave from loud speaker mainly to the direction that it is propagated, and namely motion of membrane is near the direction of the sound reception person of supposition.On the contrary, " backward directions " represent with forwards in the opposite direction.Outer driver is mid-driver 220, and inner driver is high frequency driver 210.In publication WO/2009/109228, disclose the structure of preferred Driven by Coaxial cell arrangement, and this structure is incorporated herein by reference.Driver 210,220 is preferably installed to mounting 201, and make the rotationally symmetric axis of the acoustic axis 202 of driver 210,220 and the first driver element 200 coaxial, this is useful to the Design and manufacture of casing 100.Because the first driver element 200 and driver 210,220 share acoustic axis 202, so casing 100 especially can be configured to have correct directivity in concordant installation application.Within this context, the direction of the average rotationally symmetric axis of the first driver element 200 is called as axial direction.The axial direction with the driver element in asymmetrical cross section is the central axis of this unit substantially, and this central axis is preferably coaxial with the acoustic axis of driver.Correspondingly, orthogonal relative to axial direction direction is called as radial direction.

Driver element mounting 201 surrounds driver 210,220, and provides the foundation for modular event driven unit, can reproduce in various applications to the installation of this modular event driven unit by only using the driver element of a type.The interior inclusion of mounting 201 support drive unit 200, the magnet of described interior inclusion such as driver 210,220 and supporting construction.The cylindrical mounting 201 of driver element 200 has been provided with at least three sealing surfaces 204.As shown in Figure 3, the rear plate of mounting 201 and header board have outer ring-like sealing surfaces, and rear axial damper and front axle fit on this outer ring-like sealing surfaces between installation erecting stage to damper.Similarly, the outer cover of mounting 201 is provided with the groove (Fig. 1) for holding radial damper.Hereinafter described damper is described in more detail.These sealing surfaces 204 of driver element mounting 201 serve as the mounting points of specific embodiment described herein.As content of the discussions after a while, different driver elements can have different mounting points.In general, therefore the point that driver element is fixed to casing from it is regarded as mounting points.In conventional drive unit, mounting points will be positioned on the inner surface of flange, and the driver element of this flange is connected to the front surface of casing.

First driver element 200 is arranged in the first driver element capsule 110, and this capsule embeds in described casing 100.Capsule 110 can be independently housing, but capsule 110 preference is as integrally made by the molded remainder with casing 100 structure as shown in Figure 4.Capsule 110 comprises housing 111, and the inner mold of this housing is designed to receive driver element 200.Capsule 110 is therefore, it is possible to be regarded as the device for driver element 200 being fixed to casing 100.As previously mentioned, for manufacture reason, the preferable shape for the inner mold of housing 111 is cylindrical.After circular, plate 112 adapts to the rear end of housing 111, for the rear end of sealed enclosure 110.According to a fixing aspect of the first driver element, the device for driver element 200 being fixed to casing 100 is arranged to outwards install driver element 200 from the inside of casing 100.Contribute to fluid-tight engagement, rear plate 112 is provided with through hole, and the rear surface of housing 111 is provided with the corresponding screwed hole for holding screw attachment.Described joint adopts as lower seal further or adopts conventional annular seal and O type ring to seal: the seal can be connected with the rear axial damper described after a while and be provided.Correspondingly, the front end of capsule 110 is closed by the inner surface portion of the neighboring of the opening 101 of casing 100.In other words, the opening 101 in the front end around tank 100 of capsule 110, the inner surface of this casing forms flange thus, and this flange forms the ring-type header board 113 of driver element capsule 110.

Ring-type header board 113 is used for the front end of driver element 200 being installed to capsule 110 and being therefore installed to casing 100.The inner surface of imperfect front panel 113 is suitable for engaging to damper 412 with the front axle shown in Fig. 1.According to an embodiment, front axle is ring-shaped rubber seals to damper 412, and the front surface of driver element mounting 201 is sealed to the inner surface of the ring-type header board 113 of capsule 110 by this rubber seal.Front axle also can be arranged by replacement device to damper 412, the axial damper of small cylindrical of multiple such as coils that described replacement device is such as opened along the spatial dispersion between driver element 200 and ring-type header board 113.In general, axially suspension can realize in every way.

Front axle forms a part for the suspending apparatus 410 between the first driver element 200 and casing 100 to damper 412.The rear axial damper 411 of first suspending apparatus 410 is strengthened, and this rear axial damper 411 adapts between the inner surface of the rear end of driver element 200 and the rear plate 112 of housing 110.Rear axial damper 411 is preferably shaped to and makes it between rear plate 112 and housing 111 and between rear plate 112 and driver element 200, provide sealing.Such shape by have be similar to front axle to damper 412 but have additional after flange shape raised structure obtain, this projection is configured as the match surface sealing rear plate 112 and housing 111.Alternately, these two kinds of seals can with such as independently O type ring provide.Generally speaking, rear axial damper 411 and front axle form axial suspending apparatus to damper 412, this axial suspending apparatus be suitable for from mounting 201 below and driver element mounting 201 is flexibly suspended casing 100 above, for allowing the suspension in forward and backward both direction.Within this context, suspension motion is considered to occur from the resting position of driver element.In other words, known suspending apparatus only provides suspension in one direction, because depart from return motion not from the resting position of driver element but from the extreme position departed from.

Driver element erecting device according to the present invention has elastic mounting device, and this elastic mounting device provides the elastic mounting from the both sides of driver element mounting points to rigid box 100 substantially.Within this context, term " elasticity " represents that object expection is surrendered between its conventional operating period.Such as, casing 100 is designed under normal Sound reproducing sight unyielding, is just considered to be the namely stiff of rigidity within this context.Except previously described axially suspension (damper 411,412), according to one embodiment of present invention, driver element 200 is provided with rear radial damper 413 and front radial damper 414, and described rear radial damper and front radial damper form the radial component of suspending apparatus 410.Radial damper 413,414 is simple O type ring preferably, to fit on the inner surface of housing 111 and the outer cover of driver element mounting 201 between corresponding groove (Fig. 1).Alternately, radial other device suspending the multiple string parts (string pieces) placed by the outer cover such as along driver element mounting 201 provides.The size of groove is preferably to admit of end-play between radial damper 413,414 and mounting 201.In other words, groove is enough wide makes radial damper 413,414 move freely in groove and work with the principle of bearing.Therefore, radial damper 413,414 provides radial suspension and the axial freedom between driver element 200 and casing 100.

Damping structure benefits from resonance frequency and the poised state of different sub-systems, and it is reached together with the suitable isolation of use and erecting device by adjustment force vector (by quality, magnetic force, electric current).Based on acoustical behavior and the body structure of expection, define to damper by using such as Newton interpolation algorithm and equivalent mass-spring and the method for electromechanical analogy and relevant parameter is installed.These imply that the following fact: the displacement amplitude of each subsystem has maximum under resonance frequency.In addition, if effect force vector thereon important and be zero, then whole system such as the first driver element reaches poised state and keeps static.Because some components of power are frequency dependents, so utilize broad frequency band damper preferably by the loss factor of damping adjusting device and elasticity.Like this, can adjust damper (such as O type ring) and the installation be associated or accommodating mechanism thus minimize the displacement amplitude of whole system.Therefore, quality and frequency dependent or variable excitation force and motion speed eliminate by selecting the elastic damping device with suitable loss.This together with for resilient attachment part mechanical dimension design and housing suitable Machine Design by vibration compensation to expectation level.Consider above-mentioned factor, in one embodiment of this invention, in order to realize the acoustical behavior of expecting, the elastomeric O-rings with 3mm diameter of section and 144.5mm overall diameter is favourable.

Because on the one hand the first driver element 200 is fixed to casing 100 and suspends relative to this casing, so driver element 200 is isolated with the remainder of inside of the casing 100 with driver element capsule 110 on the other hand.Should be used in the embodiment of realization at described driver element erecting device with multichannel loudspeaker, isolation provides protection first driver element 200 from the benefit because of the pressure caused by the second driver element motion.If do not have capsule 110 as under conventional speakers situation, so the oscillating movement of the diaphragm of the second driver element and bass drivers produces back pressure in casing, and this back pressure affects other driver being exposed to described pressure oscillation on rear side of it.In other words, the motion of the first driver element diaphragm is subject to the obstruction of the back-pressure cutting edge of a knife or a sword (counter pressure front) produced by the second driver element, and the performance of this back-pressure cutting edge of a knife or a sword to the first driver element has reduction effect.This problem solves at the auxiliary lower of above-mentioned capsule 110.Therefore, can carry out independent of described effect the design of the second driver element 300.Thus the ventilation of diaphragm and sound ring frame can be designed out and out, thus avoid the pressure initiation under diaphragm, thus also improve the performance of the second driver element preferably bass drivers.

As shown in Figure 2, driver element erecting device principle is also applicable to install more conventional driver element, simultaneously from the angle of unexpected conduction vibration, is gone to connect by driver element from casing 100.According to an embodiment, the second driver element 300 of loud speaker is arranged in the second driver element capsule 120, and this second driver element capsule embeds in the second opening 102 of casing.Alternately, the second opening 102 can be only mounting points in single driver element device together with the second driver element capsule 120.Correspondingly, there is multiple second driver element 300 and do not have, in the application of single or multiple first driver element 200, casing 100 can have more than one such mounting points.But in the embodiment of Fig. 2 and Fig. 5, the second driver element 300 is made up of a Low frequency drivers 310, wherein they share mounting 311.According to another embodiment, the second driver element 300 is Driven by Coaxial unit, and it comprises two or more nested drivers.

As illustrated in detail in figure 6, the second driver element capsule 120 being embedded into the second opening 102 of casing 100 comprises relatively narrow housing 121, and this housing is suitable for flange and second suspending apparatus 420 of accommodation second driver element mounting 311.According to an embodiment, the second suspending apparatus 420 comprise fit in mounting 311 both sides on axial damper, namely mounting 311 fits in rear axial damper 421 and front axle between damper 422.Axial damper 421,422 can be simple ring-shaped rubber plate, and its front surface and rear surface are provided with for improvement of flexible annular recess.Alternately, axial damper 421,422 can construct by simply suspending elastic component, and described elastic component such as has the rubber ring of internal circumferential groove, and the flange of mounting 311 fits in this inner groovy, as shown in Figure 6.As seen, single rubber ring also forms radial damper 423, and this radial damper is suitable for providing resilient radial to suspend between the second driver element 300 and casing.Therefore the flange of mounting 311 and the contact point of axial damper are the mounting points of the second driver.The flange of axial damper 421,422 and mounting 311 is preferably from the support of inner surface of neighboring of the second opening 102 being subject to casing above.This inner surface forms flange, and this flange forms the ring-type header board (annular plate 113 see the first capsule 110) of the second driver element capsule 120.By using the front supporting member of the fixing part of casing as the second capsule 120, the front surface of casing can avoid because of such as head of screw cause discontinuous.The front supporting member of the second driver element capsule also can be provided with can fixed head.

As further shown in Figure 6, the rear support of the second driver element capsule 120 is provided with rear plate 122, and this rear plate has the medium pore of the parts for the second driver element 300, the magnet of described parts such as Low frequency drivers 310 and supporting construction thereof.According to a fixing aspect of the second driver element 300, the device for driver element 300 being fixed to casing 100 is arranged to outwards install driver element 300 in casing 100.The difference of the rear plate 122 of the second capsule 120 and the rear plate 112 of the first capsule 110 is, the former is 122 by capsule 120 internal insulation with casing 100.The rear sound wave produced by the diaphragm 312 of Low frequency drivers 311 is therefore, it is possible to be directed to the inside of casing 100.But this sound wave can not affect the performance of the first driver element 200, because it is arranged in the first driver element capsule 110 of isolation.Joint between the rear plate 122 of the second capsule 120 and housing 121 can be arranged to be similar to the such of the first capsule 110.

As depicted, the new ideas of installing driver element can be applied to various different capsule.A preferred embodiment is installed to speaker enclosure, but be also favourable by this application of installation in wall-embedded loud speaker.Wall-embedded loud speaker is normally embedded into the driver element in wall, is provided with dimple for receiving driver element in wall.In conventional wall-embedded loud speaker, driver element is connected to wall from flange bolt, screw transparent walls surface.By applying erecting device similar as shown in Figure 1, installation can significantly improve.In a wall-embedded application (not shown), receiving dimple and power-supply wiring and audio frequency wiring are set to wall, and driver element is above-mentioned first driver element 200(Fig. 3 and Fig. 7 preferably) be embedded in this dimple.With header board similar as shown in Figure 1, driver element is sealing into dimple, this header board has the circular port for appearing driver element.Adopt the suitable means of such as screw that header board is fixed to wall.Driver element is suspended wall by the suspending apparatus adopting above-mentioned reference diagram 1 and Reference numeral 410 to describe in greater detail.Axial damper and the radial damper of this unit front and back provide multiaxis to suspend, and thus unexpected vibration is prevented from being transmitted to wall thus produces too much resonating surface.
