These two speakers v / er the neoen and: -r or in another design also coaxial in- arranged one another. The latter execution can be brought together Build and therefore expensive, while the first type has the disadvantage that an unsyraKietrical sounddTuck field is created.Hs ict aich ekaolit, z-Lin! in and to arrange several loudspeakers one above the other and to columns- föraicn hcrpcr to vereiiien; such an eoilde is his elongated parts are suitable for installation in devices and net. The aim of this is a more favorable and also '/ irt- more socially north now. multiple speakers. arei or uehr loudspeakers on one common Jchailwand arranged along a journey in such a way that their membrane baskets come as close as possible to each other and another], High frequency speakers are preferred by radiating tweeters in the middle of this tour. This loudspeaker arrangement tion generates a largely symmetrical Jchaildruckfeld and is in it both the columnar summary of several phonetic speak as well as the division of a high and a 'Jjiefton loudspeaker, ie has each coaxial in- u IL Li Li nested high-and-low speaker systems ID Advantage of a simpler and cheaper manufacture and is in- ' folje of the division of the lower-tone hiederabe au: several phonetic Speakers-JyBteme not only with regard to the sound distribution cheaper, but contrary to all expectations due to the use of smaller and therefore mass-produced woofers also cheaper in terms of manufacturing costs than an arrangement with only one woofer correspondingly greater power and a tweeter.

In der Zeichnung ist der Gegenstand der Neuerung schematisch dargestellt. Mit 1,2,3,4,sind die Membrankörbe von vier beispielsweise elektrodynamischen. Lautsprechern bezeichnet, deren Mittelpunkte längs eines Kreises 5 von einem solchen Durchmesser gleichmässig verteilt sind, dass die Ränder der Membrankörbe einander möglichst nahekommen. Im Mittelpunkt des Kreises @ ist der Hochton-Lautsprecher 6 angeordnet, für. dessen kleinere Abmessungen der von den Membran-Körben 1 bis 4 freigelassene Raum völlig ausreicht.In the drawing, the subject of the innovation is shown schematically. With 1,2,3,4, the membrane baskets of four, for example, are electrodynamic. Speakers denotes whose centers along a circle 5 of such a diameter are evenly distributed so that the edges of the membrane baskets each other as possible to come close. The tweeter loudspeaker 6 is arranged in the center of the circle @, for. its smaller dimensions that of the membrane baskets 1 to 4 released Space is completely sufficient.

Sämtliche Lautsprechersysteme sind auf einer Schallwand 7 befestigt.All loudspeaker systems are attached to a baffle 7.

Anstelle von vier Tiefton-Lautsprechern können auch drei oder mehr als vier vorgesehen werden. Aus der Zeichnung ist ohne weiteres er- 0 CD sichtlich, dass das von dieser Lautsprecher-Anordnung erzeugte Schalldruckfeld weitgehend symmetrisch und wegen der Zusammendrängung der Membrankörbe auch weitgehend einheitlich ist. Um die Schallstrahlung noch mehr zusammen zu halten, können die Achsen der Tiefton-Lautsprecher um einen kleinen Winkel von wenigen Win- kelgraden gegen die Mitte geneigt werden. ZD Um dem Hochton-Lautsprecher nur diejenige Leistung zuzuführen, zu deren Abstrahlung er bevorzugt geeignet ist, erfolgt die Speisung der Lautsprecher-Anordnung zweckmässig unter Einschaltung eines IIochpass-Filters 3 : n der Weise, dass nur die höheren Frequenzen des wiederzugebenden Klangbildes zum Hochtonlautsprecher gelangen, während die Tiefton-Lautsprecher mit dem ganzen Frequenz- ; spektrum beaufschlagt werden.'' ? Um das Klangbild willkürlich beeinflussen und beispielsweise bei der Wiedergabe von Schallplatten das im hohen Frequenzbereich liegende Nadelgeräusch schwächen zu können, ist es empfehlenswert, einen Regler für die dem Hochtonlautsprecher zuzuführende Leistung vorzusehen.Instead of four woofer speakers you can use three or more can be provided as four. From the drawing it is easy to see 0 CD It is evident that the sound pressure field generated by this loudspeaker arrangement is largely symmetrical and, because of the crowding together of the membrane baskets, is also largely uniform. In order to keep the sound radiation together even more, the axes of the woofers can be turned around a small angle of a few wind- degrees to be inclined towards the center. ZD In order to only supply the high-frequency loudspeaker with the power that it is preferred to emit, the loudspeaker arrangement is expediently fed with the inclusion of a high-pass filter 3: in such a way that only the higher frequencies of the sound image to be reproduced reach the high-frequency loudspeaker, while the woofer with the whole frequency; spectrum can be applied. ''? In order to be able to arbitrarily influence the sound image and, for example, to be able to weaken the needle noise in the high frequency range when playing records, it is advisable to provide a regulator for the power to be supplied to the tweeter.
