Abstract

Erfindungsgemäß wird eine Schwingspulenanordnung und ein Herstellungsverfahren für eine Schwingspulenanordnung angegeben, wobei die Schwerpunkte auf der Gewichtsreduzierung und der kostengünstigen Herstellung liegen.
Ausgehend vom Stand der Technik werden Schwingspulenanordnungen so ausgebildet, daß die Lötpunkte 21, welche die Spulendrähte 19 mit den Litzen 22 leitend verbinden, über eine separate Klebenaht mit der Membran 28 oder dem Schwingspulenträger 13 verbunden werden. Unabhängig davon, daß die dauerhafte Fixierung der Lötpunkte 21 gewichtserhöhend wirkt, sind in Abhängigkeit von der gewählten Verfahrensführung weitere Gewichtserhöhungen notwendig.
Erfindungsgemäß wird daher angegeben, die Lötpunkte 21 gleichzeitig in der Klebenaht 26 anzuordnen, mit welcher die Zentriermembran 10 mit dem Schwingspulenträger 13 verbunden ist. Dazu ist der erste Bereich 12 der Zentriermembran 10 so ausgebildet, daß sich dieser Bereich 12 in Richtung zum oberen Ende 16 Schwingspule 18 öffnet. Sind die Lötpunkte 21 in der Klebenaht 26 angeordnet, ist eine Schwingspulenanordnung geschaffen, welche sich durch eine geringe Bauhöhe, eine gute Belastbarkeit und eine ausgezeichnete Höhenwiedergabe auszeichnet.

According to the invention, a voice coil arrangement and a production method for a voice coil arrangement are specified, the emphasis being on the weight reduction and the cost-effective production.
Starting from the prior art voice coil assemblies are formed so that the solder pads 21, which connect the coil wires 19 conductively connected to the strands 22, are connected via a separate adhesive seam with the membrane 28 or the voice coil bobbin 13. Regardless of the fact that the permanent fixation of the soldering points 21 acts to increase the weight, further weight increases are necessary depending on the chosen process control.
According to the invention, it is therefore specified to arrange the soldering points 21 simultaneously in the adhesive seam 26, with which the centering membrane 10 is connected to the voice coil bobbin 13. For this purpose, the first region 12 of the centering diaphragm 10 is formed so that this region 12 opens in the direction of the upper end 16 voice coil 18. If the soldering points 21 are arranged in the adhesive seam 26, a voice coil arrangement is created, which is characterized by a low overall height, a good load capacity and an excellent height reproduction.
