Abstract

A frame for a loudspeaker unit used, for example, in a television receiver, has provisions for optionally fastening one type of loudspeaker to the frame by a positively-locking fastening arrangement or another type of loudspeaker by screw fastening. Specifically, the frame includes both a positively-locking click-stop arrangement for snap-in fastening, and also clip elements for holding the loudspeaker during a screwing operation.

Description

Eine Lautsprechereinheit besteht im allgemeinen aus einem als Schallführung dienenden Rahmen mit einer Schalldurch­trittsöffnung und einem daran befestigten Lautsprecher. Der Rahmen kann z.B. der Frontrahmen eines Fernsehempfängers, die Vorderwand einer Lautsprecherbox, die Wand eines Rund­funkgerätes oder das Armaturenbrett eines Autos sein.A loudspeaker unit generally consists of a frame serving as a sound guide with a sound passage opening and a loudspeaker attached to it. The frame can e.g. the front frame of a television receiver, the front wall of a loudspeaker box, the wall of a radio or the dashboard of a car.

Es ist bekannt, den Lautsprecher an dem Rahmen über eine forschlüssige Rastverbindung, ein sogenanntes snap-in, zu befestigen. Dabei kann die Befestigung durch eine reine Translationsbewegung des Lautsprechers erfolgen, was insbe­sondere für einen Einbau mit Automaten vorteilhaft ist. Au­ßerdem werden bei dieser Lösung keine Schrauben benötigt, die zusätzliche Bauteile darstellen und den Befestigungsvor­gang verlängern. Eine solche Verbindung ist insbesondere für Lautsprecher vorteilhaft, die einen Korb aus Kunststoff auf­weisen.It is known to fasten the loudspeaker to the frame by means of a positive snap-in connection. The attachment can be done by a pure translational movement of the speaker, which is particularly advantageous for installation with machines. In addition, this solution does not require screws that represent additional components and extend the fastening process. Such a connection is particularly advantageous for loudspeakers that have a plastic basket.

Es ist andererseits bekannt und in manchen Fällen notwendig, den Lautsprecher an dem Rahmen mit Schrauben zu befestigen. Diese Lösung wird insbesondere bei Lautsprechern mit einem Metallkorb bevorzugt, weil dafür eine snap-in-Befestigung weniger vorteilhaft ist. In manchen Geräten werden wahlweise Lautsprecher mit einem Kunststoffkorb und mit einem Metall­korb verwendet, so daß es erforderlich sein kann, unter­schiedliche Befestigungsarten vorzusehen.On the other hand, it is known and in some cases necessary to attach the speaker to the frame with screws. This solution is particularly preferred for loudspeakers with a metal basket, because snap-in fastening is less advantageous for this. In some devices, speakers with a plastic basket and a metal basket are optionally used, so that it may be necessary to provide different types of mounting.

Der Erfindung liegt die Aufgabe zugrunde, einen Rahmen für einen Lautsprecher so auszubilden, daß an demselben Rahmen wahlweise Lautsprecher über eine formschlüssige Rastverbin­dung und eine Schraubverbindung automatengerecht befestigt werden können.The invention has for its object to provide a frame for a loudspeaker in such a way that loudspeakers can optionally be attached to the same frame using a positive locking connection and a screw connection.

Diese Aufgabe wird durch die im Anspruch 1 beschriebene Er­findung gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.This object is achieved by the invention described in claim 1. Advantageous developments of the invention are described in the subclaims.

Durch die erfindungsgemäße Lösung werden beide Befestigungs­arten, nämlich die mittels einer formschlüssigen Rastverbin­dung ohne Schrauben und die mit Schrauben an demselben Rah­men optimiert. Für beide Befestigungsarten kann daher dersel­be Rahmen verwendet werden, was insbesondere für die Herstel­lung und die Lagerhaltung des Rahmens vorteilhaft ist. Beide Befestigungsarten können durch eine reine Translationsbewe­gung des Lautsprechers erfolgen, also eine Bewegung, bei der sich alle Punkte des Lautsprechers auf einer geraden Linie bewegen. Das ist insbesondere vorteilhaft für den Einbau des Lautsprechers mit Automaten.The solution according to the invention optimizes both types of fastening, namely that by means of a positive locking connection without screws and that with screws on the same frame. The same frame can therefore be used for both types of fastening, which is particularly advantageous for the manufacture and storage of the frame. Both types of attachment can be done by a translational movement of the speaker, i.e. a movement in which all points of the speaker move in a straight line. This is particularly advantageous for installing the speaker with machines.

Die Erfindung wird im folgenden anhand der Zeichnung erläu­tert. Darin zeigen

  • Fig. 1 den Ausschnitt aus dem Frontrahmen eines Fernsehempfängers von der Rückseite und
  • Fig. 2 eine Draufsicht auf die Fig. 1, teilweise im Schnitt.
The invention is explained below with reference to the drawing. Show in it
  • Fig. 1 shows the detail from the front frame of a television receiver from the back and
  • Fig. 2 is a plan view of FIG. 1, partly in section.

Fig. 1 zeigt den Frontrahmen 1 eines Fernsehempfängers mit der Schalldurchtrittsöffnung 2 für einen Ovallautsprecher. An diametral gegenüberliegenden Stellen der Öffnung 2 ist jeweils ein starrer Vorsprung 3 mit einer Öffnung 4 vorgese­hen, der mit dem Rahmen 1 ein Kunststoff-Spritzteil bildet.Fig. 1 shows the front frame 1 of a television receiver with the sound passage opening 2 for an oval speaker. At diametrically opposite points of the opening 2, a rigid projection 3 is provided with an opening 4, which forms a molded plastic part with the frame 1.

Außerdem ist an diametral gegenüberliegenden Stellen der Öffnung 2 je ein aus der Ebene des Rahmens 1 hervorragender Vorsprung 5 vorgesehen, der durch einen Schlitz 6 in Rich­tung der Ebene des Rahmens 1 federnd ausgebildet ist und an seinem oberen Ende einen widerhakenartigen Ansatz 7 mit ei­ner Schräge aufweist. Der Rahmen 1 ist außerdem mit vier Gewindebohrungen 8 zur Aufnahme von selbstschneidenden Schrauben versehen.In addition, a projection 5 is provided at diametrically opposite points of the opening 2, which protrudes from the plane of the frame 1, is formed resiliently by a slot 6 in the direction of the plane of the frame 1 and has a barb-like projection 7 with a bevel at its upper end . The frame 1 is also four Provide threaded holes 8 for receiving self-tapping screws.

Für die Befestigung eines Lautsprechers mit Kunststoffkorb im Sinne einer formschlüssigen Rastverbindung ohne Schrauben wird der Lautsprecher in Richtung senkrecht zur Ebene des Rahmens 1 auf den Rahmen aufgesetzt. Dabei werden federnde Vorsprünge an dem Korb des Lautsprechers durch die Vorsprünge 3 ausgelenkt, bis schließlich widerhakenartige Enden der Vorsprünge am Lautsprecher in die Öffnungen 4 der Vorsprünge 3 einrasten. Der Lautsprecher ist dann an dem Rahmen 1 formschlüssig und spielfrei gehaltert. Die Vorsprünge 5 an dem Rahmen 1 werden dabei nicht benötigt und haben für die Halterung des Lautsprechers keine Bedeutung. Eine Befestigung eines Lautsprechers über eine formschlüssi­ge Rastverbindung, ein sogenanntes snap-in, ohne Schrauben an dem Frontrahmen eines Gehäuses eines Fernsehempfängers ist beschrieben in dem DE-GM 84 02 128.For the attachment of a loudspeaker with a plastic basket in the sense of a positive locking connection without screws, the loudspeaker is placed on the frame in the direction perpendicular to the plane of the frame 1. Resilient projections on the basket of the loudspeaker are deflected by the projections 3 until barb-like ends of the projections on the loudspeaker finally snap into the openings 4 of the projections 3. The loudspeaker is then held on the frame 1 in a form-fitting manner and without play. The projections 5 on the frame 1 are not required and are of no importance for the mounting of the loudspeaker. The attachment of a loudspeaker via a positive locking connection, a so-called snap-in, without screws to the front frame of a housing of a television receiver is described in DE-GM 84 02 128.

Für die Befestigung eines Lautsprechers mit Metallkorb wird der Lautsprecher ebenfalls in Richtung senkrecht zur Ebene des Rahmens 1 aufgesetzt. Der Flansch des Lautsprechers trifft dabei zunächst auf die Ansätze 7 und bewirkt eine Aus­lenkung der federnden Vorsprünge 5 radial zur Öffnung 2. In der Endstellung greift der Flansch des Lautsprechers in die Schlitze 6 ein, und der Lautsprecher ist jetzt durch die Vorsprünge 5 an dem Rahmen 1 gehaltert. Diese Halterung ist keine endgültige Befestigung, sondern dient nur für eine La­gefixierung, auch pre-fixation genannt, in einer Lage, in der Löcher des Flansches des Lautsprechers mit den Gewindebohrungen 8 übereinstimmen. Der Lautsprecher braucht für den Schraubvorgang dann nicht mehr gehalten zu werden, so daß der Bedienende beide Hände für den Schraubvorgang frei hat oder der Schraubvorgang mit Automaten erfolgen kann. Nach dieser Vor-Befestigung oder Lage-Fixierung des Lautsprechers werden zwei oder vier Schrauben durch die Boh­rungen im Flansch des Lautsprechers manuell, mit einem Hand­schrauber oder mit Automaten in die Gewindebohrungen 8 einge­dreht, wodurch die endgültige Befestigung des Lautsprechers an dem Rahmen 1 erfolgt. Die zur vorübergehenden Lage-Fixie­rung und Halterung dienenden Vorsprünge 5 haben dann für die Befestigung des Lautsprechers keine Bedeutung mehr. Die Vorsprünge 3 haben bei dieser Art der Befestigung an sich keine Bedeutung. Sie können allenfalls zusätzlich zur Füh­rung und als Anschlag für den Flansch des Lautsprechers die­nen.To attach a loudspeaker with a metal basket, the loudspeaker is also placed in the direction perpendicular to the plane of the frame 1. The flange of the loudspeaker first meets the lugs 7 and causes the resilient projections 5 to deflect radially to the opening 2. In the end position, the flange of the loudspeaker engages in the slots 6, and the loudspeaker is now on the frame through the projections 5 1 held. This bracket is not a final attachment, but is only used for a position fixation, also called pre-fixation, in a position in which holes in the flange of the loudspeaker correspond to the threaded bores 8. The loudspeaker then no longer needs to be held for the screwing process, so that the operator has both hands free for the screwing process or the screwing process can be carried out with automatic machines. After this pre-attachment or location fixation of the Loudspeaker two or four screws are screwed through the holes in the flange of the loudspeaker manually, with a hand screwdriver or with automatic machines into the threaded bores 8, as a result of which the loudspeaker is finally attached to the frame 1. The projections 5 used for temporarily fixing and holding the position are then no longer of importance for fastening the loudspeaker. The projections 3 are of no importance in this type of attachment. They can also serve as a guide and as a stop for the flange of the speaker.

Die Vorsprünge 3,5 liegen gegenüber der langen Achse der ovalförmigen Öffnung 2 um einen Winkel von etwa 15° ver­setzt. Das hat folgenden Vorteil: Wenn die Vorsprünge genau in Richtung der langen Achse liegen, wäre der Raumbedarf in Richtung dieser langen Achse größer. Das ist besonders nach­teilig bei einem Fernsehempfänger, in dem der Platz für die Anbringung des Lautsprechers beengt ist. Durch die versetzte Lage gegenüber der langen Achse kann ein Raumgewinn erzielt werden. Das bedeutet, daß der Abstand der beiden Vorsprünge 3 oder 5 voneinander in Richtung der langen Achse A verkleinert wird.The projections 3, 5 are offset from the long axis of the oval-shaped opening 2 by an angle of approximately 15 °. This has the following advantage: If the protrusions lie exactly in the direction of the long axis, the space requirement in the direction of this long axis would be greater. This is particularly disadvantageous in the case of a television receiver in which the space for mounting the loudspeaker is limited. The offset position in relation to the long axis allows space to be gained. This means that the distance between the two projections 3 or 5 from each other is reduced in the direction of the long axis A.
