Description
Die Erfindung betrifft einen elektrischen Tonabnehmer mit seitlich der Polschuhe angeordneten, aus nicht magnetischem Material bestehenden Ankerlagern.' Bei bekannten Tonabnehmern dieser Art bestehen die Lager aus mehreren Einzelteilen, wie z. B. Brücken, die gesondert hergestellt und bei dem Zusammenbau auch unter sich genau einjustiert werden müssen. Um die Herstellung und den Zusammenbau zu erleichtern, bildien daher erfindungsgemäß die Lagerkörper einen geschlossenen Ring.The invention relates to an electric pickup with the side of the pole pieces, armature bearings made of non-magnetic material. ' In known pickups of this type, the bearings exist from several individual parts, such as B. Bridges that are manufactured separately and during assembly must also be precisely adjusted among themselves. To facilitate manufacture and assembly, therefore, form according to the invention the bearing body has a closed ring.
Auf der Zeichnung ist inThe drawing shows in
Abb. ι in einer teilweise geschnittenen Vorderansicht und inFig. Ι in a partially sectioned front view and in
Abb. 2 in einer Draufsicht ein Ausführungsbeispiel dargestellt.Fig. 2 shows an embodiment in a plan view.
Bei der Ausführungsform nach den Abb. 1 und 2 ist der von der nicht dargestellten Spule umgebene Anker r mit seinen Lagerzapfen 2, 3 in dem aus nicht magnetischem Material bestehenden Lagerkörper 4, welcher ringförmig ausgebildet ist, gelagert. Der Lagerkörper 4 ist auf der Oberseite der unteren Polschuhflanschen 5,6 der Polschuhe 7,8 a5 angeordnet und derart ausgebildet, daß die eigentlichen Lagerstellen des Lagerkörpers 4 für die Zapfen 2, 3 seitlich der Polschuhe liegen. Das obere Ende des Ankers 1 ragt in den Luftspalt zwischen den oberen Flansehen 9, 10 der Polschuhe 7, 8, welche mit dem Magneten 11 verbunden sind, während der untere Teil des Ankers in dem Luftspalt zwischen den unteren Polschuhflanschen 5,6 schwingt. Die Feststellschraube 12 zum Festhalten der nicht dargestellten Abtastnadel wird zweckmäßig innerhalb des Zapfens 3 in einem Gewinde angeordnet.In the embodiment according to FIGS. 1 and 2, the armature r, which is surrounded by the coil (not shown), is supported with its bearing journals 2, 3 in the bearing body 4, which is made of non-magnetic material and is annular. The bearing body 4 is arranged on the upper side of the lower pole piece flanges 5,6 of the pole pieces 7,8 a 5 and is designed such that the actual bearing points of the bearing body 4 for the pins 2, 3 are to the side of the pole pieces. The upper end of the armature 1 protrudes into the air gap between the upper flanges 9, 10 of the pole pieces 7, 8, which are connected to the magnet 11, while the lower part of the armature swings in the air gap between the lower pole piece flanges 5, 6. The locking screw 12 for holding the scanning needle (not shown) is expediently arranged within the pin 3 in a thread.
