Description
TIEFTON-BESCHALLUNGSEINRICHTUNG FÜR AUTOMOBILELOW-FREQUENCY AUDIO SYSTEM FOR AUTOMOBILES
Vornehmlich in Automobilen ohne Heckablage bedient man
sich aus Platzgründen gerne der Subwoofer—Satellitentechnik,
wobei vorzugsweise -für den Subwoofer Orte wie: Die Heckklappe, die Hohlräume in den Radkastenbereichen,die Fußbereiche unter
den Sitzen etc.genutzt werden.Mainly in cars without a rear shelf,
For reasons of space, the subwoofer is often used—satellite technology, with the preferred locations for the subwoofer being the tailgate, the cavities in the wheel arch areas, the foot areas under the seats, etc.
Neben der Tatsache,daß das Einbringen der Subwoo-f er lautsprecher
in die Heckklappe beim öffnen aus Gewichtsgründen Probleme bereiten kann oder der Schallaustritt aus den Radkästen-Hohlräumen
o-ftmals wegen der ungünstigen Reflektionsverhaltnisse
im Bereiche des Fahrersitzes zu Auelöschungen der Tiefstfrequenzen
nicht optimal ist,sind diese Verfahren ungünstig, weil die Schallintensität vom Bepackungsgrad der Ladefläche
abhängig ist.In addition to the fact that the installation of the subwoofer speakers in the tailgate can cause problems when opening due to weight reasons or the sound emission from the wheel arch cavities is often not optimal due to the unfavourable reflection conditions in the area of the driver's seat which cancel out the lowest frequencies, these methods are unfavourable because the sound intensity depends on the level of loading of the loading area.
depends on.
Des weiteren scheidet die Unterbringung des Subwoofers unter den Sitzen praktisch deshalb aus,weil dadurch Fußfreiheit genommen wird,oder weil einfach die Sitzbefestigungen die Unterbringung verhindern.Furthermore, placing the subwoofer under the seats is practically impossible because it would take up space for your feet, or because the seat mounts simply prevent it from being placed there.
Die Unterbringung in den Türbereichen oder unter dem Armaturenbrett
scheitert meist daran,daß vornehmlich in Neuwagen
Ausschnitte in den Verkleidungen nicht toleriert werden.
Die Erfindung vermeidet genannte Nachteile.
Sie nutzt den in aller Regel freien Kniekehlenbereich an
den Frontsitzen und sieht für den rechten und linken Stereokanal
vorzugsweise getrennte Subwoofersysteme in Miniaturausführung
vor,die deshalb so klein sind,weil eine in jedem Subwoofergehäuse befindliche öffnung mit definiertem
Querschnitt eine Tiefstbaßanhebeng erzeugt und mit geeigneter
Filterung für eine ausgewogene Subwoofercharakteristik
sorgt.The placement in the door areas or under the dashboard usually fails because, primarily in new cars,
Cutouts in the panels are not tolerated.
The invention avoids the above-mentioned disadvantages.
It uses the usually free back of the knee area
the front seats and provides for the right and left stereo channels preferably separate subwoofer systems in miniature design, which are so small because an opening in each subwoofer housing with a defined
Cross-section produces a deep bass boost and with suitable filtering for a balanced subwoofer characteristic
ensures.
Dieses Verfahren bringt es mit sich,daß die obere Grenzfrequenz unter anderem vom Boxenvolumen abhängig ist,so daß sie bei extremer Miniaturisierung im Bereich oberhalb der nichtortbaren Tonlagen,d.h.bei ca.300 Hz,angesiedelt sein kann.This method means that the upper limit frequency depends, among other things, on the volume of the speaker, so that in the case of extreme miniaturization it can be located in the range above the non-locatable pitches, i.e. at around 300 Hz.
Dies schränkt jedoch nicht die Verwendbarkeit für den Anwendungsfall ein,weil die Unterbringung der Subwoofer für rechts und links,den Sitzen getrennt zugeordnet ist.However, this does not limit the usability for the application, because the subwoofers for the right and left seats are located separately.
Es lassen sich natürlich auch Subwoofer einsetzen,die mit Verstärkern und Aktivweichen ausgestattet sind.Of course, subwoofers that are equipped with amplifiers and active crossovers can also be used.
Einen wichtigen Bestandteil der Erfindung bildet die Befestigung der Subwoofer an den Sitzen,so daß nach der Montage die Sitze und Subwoofer Einheiten bilden,die den gesetzlichen Bestimmungen für die Betriebssicherheit des Automobiles genügen.An important part of the invention is the attachment of the subwoofers to the seats, so that after assembly the seats and subwoofers form units that meet the legal requirements for the operational safety of the vehicle.
Diese Halterungen sind so ausgebildet,daß sie neben den Stabilitätsanforderungen die Wünsche nach universeller Anwendbarkeit und Vibrationsdämpfung erfüllen. Eine mögliche Ausführungsform wird in Fig.l gezeigt. Der Subwooferlautsprecher 1 sitzt in dem Gehäuse 2,das z.B.in dessen Rückseite 3 die definierte öffnung eingearbeitet ist.Seitlich am Gehäuse 2 sind die Rohrstücke 4 und S schwingungsgedämpft &zgr;.B.mittels Schwingmetal1teiIe befestigt.Die Winkelstücke 6 und 7 münden nach Lösen der Verschraubungen 8,9,10 und 11 in die Rohrstücke 15,16 ein. Die an den Rohrstücken 15,16 befestigten Schellen 17,18, 19 und 20 umgreifen die Rohrstücke 22,23,die zur Sitzkonstruktion gehören.These brackets are designed in such a way that, in addition to the stability requirements, they meet the requirements for universal applicability and vibration damping. A possible embodiment is shown in Fig. 1. The subwoofer loudspeaker 1 sits in the housing 2, which, for example, has the defined opening incorporated into the rear 3. The pipe sections 4 and 5 are attached to the side of the housing 2 in a vibration-damped manner, e.g. by means of anti-vibration metal parts. The angle pieces 6 and 7 open into the pipe sections 15, 16 after the screw connections 8, 9, 10 and 11 have been loosened. The clamps 17, 18, 19 and 20 attached to the pipe sections 15, 16 grip the pipe sections 22, 23, which are part of the seat structure.
Zur Verbesserung der Anpaßbarkeit können genannte Schellen auch als Einzelteile 25,26 die Rohre 15,16,22 und 23 ver— binden.To improve adaptability, the clamps mentioned can also be used as individual parts 25,26 to connect the pipes 15,16,22 and 23.
Die Rohrkonstruktion kann auch durch eine Konstruktion aus Flachmaterial 30,31 ausgeführt werden, wobei diese -für eine verbesserte Anpaßbarkeit vorzugsweise die Lochungen 32 enthalten. The tube construction can also be made from a flat material 30, 31, which preferably contains the holes 32 for improved adaptability.
Die Befestigung der Rohr-oder Flachmaterialhalterung 40 an Sitzen mit vertikal verlaufenden Standfüßen 42 kann auch mittels der Schelle 41 erfolgen.The pipe or flat material holder 40 can also be attached to seats with vertically running feet 42 using the clamp 41.
Fig.2 zeigt eine Haiterungsvariante,die dann vorteilhaft ist,wenn der Sitz vorne mit einem horizontal verlaufenden Rohr 50 ausgestattet ist.Der auf dem Träger 52 nach Lösen der Schraube 53 verschiebbare Winkel 51 umfaßt das Rohr 50 und verhindert die Abwärtsbewegung des Trägers 52. Der nach Lösen der Schraube 55 in der Horizontalen bewegliche Winkel 54 liegt ebenfalls am Rohr 50 an und verhindert die Bewegung des Tägers 52 über das Rohr 50 hinaus. Der Träger 52 ist an der Unterseite der Box 60 mittels der Schrauben 61 an der rechten Unterkante befestigt. An der linken Unterkante ist die gleiche Halterung 62 angebracht. Fig.2 shows a mounting variant that is advantageous if the seat is equipped with a horizontally running tube 50 at the front. The angle 51, which can be moved on the support 52 after loosening the screw 53, surrounds the tube 50 and prevents the support 52 from moving downwards. The angle 54, which can be moved horizontally after loosening the screw 55, also rests on the tube 50 and prevents the support 52 from moving beyond the tube 50. The support 52 is attached to the underside of the box 60 by means of the screws 61 on the right lower edge. The same bracket 62 is attached to the left lower edge.
Die Box 60 ist somit formschlüssig mit dem Rohr 50 verbunden und führt Vor-und Rückwärtsbewegungen des Sitzes mit aus. Das an der Boxenunterseite befestigte Rad 67 sorgt dabei für einen konstanten Abstand zum Fahrzeugboden.The box 60 is thus positively connected to the tube 50 and carries out forward and backward movements of the seat. The wheel 67 attached to the underside of the box ensures a constant distance from the vehicle floor.
In der Box 60 sitzt frontal der Lautsprecher 70 ,dessen Magnet 71 in die definierte öffnung 72 in der Boxenrückwand ragt, Das Rohr 50 kann auch ein anders geartetes Formteil sein.The loudspeaker 70 is located at the front of the box 60, the magnet 71 of which projects into the defined opening 72 in the rear wall of the box. The tube 50 can also be a different type of molded part.
