Fig. 2 is the front view of loud speaker modification shown in Figure 1;
Fig. 3 is the LF-response curve chart of the loud speaker of Fig. 2;
Fig. 4 is the front view of second embodiment of the invention;
Fig. 5 is the LF-response curve chart of the loud speaker of Fig. 4;
Fig. 6 strides seat in the perspective view of room corner for loud speaker of the present invention; And
Fig. 7 is the plane graph of configuration shown in Figure 6.
In each figure, Fig. 1 particularly, it is universe resonance bending wave panel-form loudspeakers 1, be roughly WO 97/09842, WO 99/37121 or WO 99/52322 described pattern, all belong to NewTransducers Limited, this loud speaker is fit to be contained in wall 2 or similar place, for example, becomes a width of cloth picture loud speaker.This loud speaker 1 comprises one around sounding board 4 and be roughly the framework 3 of rectangle, and the suspension 5 around this plate 4 utilizes is contained in the framework.The vibration exciter 6 of an inertia power type is contained on the plate 4 near the middle position part, as WO 97/09842 instructs, audio signal in response to being added in by known manner on the exciter applies the bending wave energy to plate, makes its resonance and produces voice output.
This framework also supports a fixing backboard 7, so this loud speaker constitutes a shallow enclosure space 8, as WO 99/52322 instructs.Can utilize the traditional suspension wire that is fixed on the framework top, in the mode as picture frame this framework be hanged on the wall, the framework base leans against on the wall 2 with pearl 9, and the fulcrum that this pearl forms the level that is substantially leans on the wall for framework.
The top of framework 3 has a support 10 that puts in enclosure space 8, and an electronic vibration exciter 11 is housed on it, and this exciter passes the hole 12 on the backboard 7 backward and runs into wall so that drive contact.With flexible seal 13 position that exciter 11 passes backboard 7 is sealed on the backboard.In addition, with flexible seal 14, for example foamed plastic is sealed on the wall 2 around framework 3.This exciter can be with suitable binding element 15, and for example soft sticker is connected with wall, for example the sort of type of being sold under the RTM BLU-TACK of Britain Bostik Ltd company.When operation, apply an audio signal to exciter 6 and cause plate 4 resonance and produce a voice output, and pass to wall 2 is strengthened loud speaker to order about the wall vibration LF-response via exciter 11.Configurable a pair of such exciter 11 is respectively adorned one in two corners of frame roof.It is relevant that this wall drives the essence of constructing with wall, when wall is lightweight dry plastics plate and wooden or metal partition material, promptly, under the situation of soft structure, driver can be greater than wall resistance value condition with higher, and for example brick or brick are made the wall of dense materials such as structure, and be promptly hard structured.In the situation of hard wall, can produce the effect that drives loud speaker in the piston action mode, make LF-response obtain reinforcement again.
The speaker configurations of Fig. 2 is similar to Fig. 1, unique do not exist together for, in this situation, the exciter 6 that is used for excitation plate 4 is arranged in the top of plate, as WO 99/37121 instructs.This kind situation, this plate 4 can be the pattern of printing opacity and the part that this loud speaker can constitute visual displays.
As shown in Figure 3, dotted line is represented a LF-response curve of loud speaker shown in Figure 2; Solid line represents not have the response curve of wall driver 11.As seen wall drives the low frequency output that exciter 11 can be strengthened this loud speaker.
Fig. 4 and Fig. 5 are corresponding with Fig. 2 and Fig. 3, and at the embodiment of loud speaker shown in Figure 1 roughly, drive exciter 11 but four corners of its framework 3 all are equipped with wall.
In Fig. 6 and Fig. 7, roughly loud speaker as shown in Figure 1 stride the seat constitute an enclosed cavity 16 at the room corner, this enclosed cavity 16 resonates in the mode of Helmholtz resonator at low frequency and strengthens the low frequency performance of loud speaker, also can be provided with to become to resemble to drive wall aforementioned.
The good profile loud speaker of one design can be worked on most audiorange, and has that good sound distributes and distortion is very low.Yet, when lower audio frequency, the template formula of profile loud speaker, its size becomes similar with the size of plate, and this plate begins to move as an integral unit, and can not carry out the distribution pattern radiation.Therefore, the low-limit frequency that can under distribution pattern operation, reappear for this plate of the frequency of a little higher than this lower frequency.For the plate of most of stock size, this frequency is greatly in 100 to 200 hertz scope.
The one or more extra exciter of being installed in the loudspeaker assembly by the wall of being arranged to be equipped with said units drives, and makes dress profile loud speaker on the wall can reappear lower frequency.The advantage of this kind configuration is to have overcome the weakness that panel wall can weaken low frequency sound equipment fidelity originally.Panel wall (it is made that plastic plate is installed on timber or metal frame, is institute's employing in modern most of building) and the low-frequency sound of propagating in the room vibrate alternately.Absorption that wall produced as a result and reflection and the low frequency that needs cause interference.
Drive panel wall and can cause low-frequency sound synchrotron radiation in this wall and the desired room and overcome this restriction and provide the solution that itself comprises to be contained in the specially exciter of design in the loudspeaker assembly, and in general application, increase scope above an octave for the low-frequency range restriction of reduced size profile loud speaker.
The loudspeaker panel that low frequency will be strengthened can be the pattern that generally drives in the most suitable position of close central authorities, or the pattern that drives in edge.Can be at plate near the corner with a plurality of exciters, or impose the vibrational excitation of low frequency in the mass centre of loudspeaker assembly with single or multiple exciter.Mode in corner bass excitation can be fixed on actuator-magnet on the speaker frame assembly at an easy rate, and the additional mass of framework makes it possess inertial reference under the good low frequency.
Each low frequency stimulator can be installed in its voice coil loudspeaker voice coil front mode backward, be made this voice coil loudspeaker voice coil excitation produced be applied on the wall that loud speaker installs.Utilize the reaction inertia-activated wall of the quality of actuator-magnet or actuator-magnet and speaker frame unit (if this actuator-magnet be packed on the framework), the pushing away of low frequency stimulator-La effect makes wall produce the output of a distribution pattern.When low frequency, this may need to transmit enough strength to wall.
The method that low frequency stimulator is fixed on the wall is very important because must reach easily fixing, easily remove and solid, connect firmly to prevent noise and loss.Blu-Tack (RTM) makes a kind of connection media that is used to test, but if will fix more muchly, then needs to use as materials such as two-sided tapes.With the intensity that the two-sided tape strength of fixation surpass to need, may cause to be difficult for pulling down and can't to adjust the position.The method of another head it off is that a ganoid metal or plastics disc are fixed (for example, utilizing two-sided tape) on wall, on it, coat the viscous fluid shape that can not kill be heated can be softening compound, silicone grease etc.Loud speaker is hung when in place on the wall, and being contained in disc similar on the exciter will contact with the disc on the wall.The solid curable grip that can provide perpendicular to wall is provided for fluid that applies and the air that is formed between two thin slices, thereby can not produce noise, but adjustable position or it is taken off when needed.Can between exciter and one of them disc, assemble a hinge or general-purpose the joint with guarantee and wall surface correctly align.
For the given exciter application of force, the lighter or impedance lower (with respect to the fixed mass of loudspeaker assembly) of the quality of wall, the action of wall is bigger.The quality of loud speaker can be done more greatly, so can more effectively encourage the vibration of wall when low frequency.
The quality of wall is bigger or impedance is higher, and the action of wall is littler, the substitute is, and bigger piston type action takes place loudspeaker assembly integral body.In the case, the total quality reduction with loudspeaker assembly makes the power of exciter more can impose in the air load, rather than quality is quickened, and can be the favourable practice.For the plate that the low frequency under the hard wall situation is strengthened, it is favourable that such as shown in Figure 1 speaker frame and between the walls are done airtight processing.In two kinds of situations as herein described, to compare with the situation of not utilizing the wall excitation fully, low frequency output all has enhancing.
Therefore the invention provides a kind of simple method, can improve the bass response of the resonance panel-form loudspeakers that will adorn on the wall.
