Der elektromagnetische Vibrator besteht aus einem Gehäuse von Ebonit oder ähnlichem Stoff von angenähert pilzförmiger Gestalt. Sein Stiel α ist derart ausgebildet, daß er in den äußeren Kanal des Ohres oder eine andere Öffnung des Körpers eingeführt werden kann, und umschließt einen weichen Eisenkern b, der mit seinem Gewindeende c in dem einen Ende des Stiels einstellbar sitzt und sich der Länge nach durch eine Spule mit einer Wicklung d von feinem isolierten Draht erstreckt. Eine zwischen der Spule d und der Wand des Stieles α eingeschaltete Eisenhülle e, welche aus einem gespaltenen Rohr oder aus dünnem, die Spule umschließendem Metallblech zur Bildung eines Längsschlitzes e¹ bestehen kann (Fig. 4), bildet ein äußeres ringförmiges Polstück für den Magneten. Das innere Ende der Hülle stützt sich gegen eine Eisenscheibe f, welche auf dem Boden oder inneren Ende der Bohrung des röhrenförmigen Stiels ruht und eine mittlere Öffnung zum Durchtritt des Kerns b besitzt, um Kontakt mit' der Scheibe herzustellen.The electromagnetic vibrator consists of a housing made of ebonite or similar material of approximately mushroom shape. Its stem α is designed so that it can be inserted into the outer canal of the ear or another opening in the body, and encloses a soft iron core b, which sits adjustable with its threaded end c in one end of the stem and extends lengthwise extending through a coil with a winding d of fine insulated wire. An iron sheath e inserted between the coil d and the wall of the stem α , which can consist of a split tube or of thin sheet metal enclosing the coil to form a longitudinal slot e ¹ (Fig. 4), forms an outer ring-shaped pole piece for the magnet . The inner end of the sheath rests against an iron disc f which rests on the bottom or inner end of the bore of the tubular stem and has a central opening for the passage of the core b to make contact with the disc.

Der feste Kern b erstreckt sich nicht durch die ganze Länge der Spule d, deren äußeres Ende vielmehr durch einen besonderen Kern g ausgefüllt wird, der sowohl den Anker des Elektromagneten als auch den beweglichen Kern des aus der Spule bestehenden Solenoids bildet.The fixed core b does not extend through the entire length of the coil d, the outer end of which is rather filled by a special core g , which forms both the armature of the electromagnet and the movable core of the solenoid consisting of the coil.

Das äußere Ende dieses Kernankers sitzt an einer stählernen Blattfeder h, welche einen Hohlraum in dem erweiterten pilzförmigen Kopf j des Gehäuses überbrückt und an einem Ende k durch einen Stift 0. dgl. an einem aus leitendem Material bestehenden, die Mündung des Gehäuses umgebenden Ring I befestigt ist. Das andere Ende m der Feder ist zwischen dem Ring I und dem Rande des pilzförmigen Kopfes / lose eingeklemmt, so daß der Kernanker g genügende Bewegungsfreiheit hat. Der Ring /, welcher durch in Aussparungen I² an dem Rande des pilzförmigen Kopfes j eintretende Ansätze Z¹ auf seiner Unterseite gegen Drehung gesichert ist, wird durch den Deckel η in seiner Lage gehalten. The outer end of this core armature sits h to a steel leaf spring which j a cavity in the expanded mushroom-shaped head bridges of the housing and at one end of the housing k the like by a pin 0.. At one made of conductive material, the orifice ring surrounding I is attached. The other end m of the spring is clamped loosely between the ring I and the edge of the mushroom-shaped head / so that the core anchor g has sufficient freedom of movement. The ring /, which is secured against rotation on its underside by lugs Z ¹ entering into recesses I ² on the edge of the mushroom-shaped head j , is held in its position by the cover η.

Durch den Ring I wird der Strom von der Feder h durch den Draht 0 nach dem einen Ende der Wicklung geleitet (Fig. 5), während ihr anderes Ende an die Klemme fi ange-The current from the spring h is passed through the ring I through the wire 0 to one end of the winding (Fig. 5), while its other end is connected to the terminal fi .

Claims

is closed, which is connected to one pole of the energy source. On the outside of the bridge spring h there is an auxiliary or buffer spring q, which is lined with non-oxidizable metal at the point r and forms the movable member of the interrupter, the other or stationary member of which consists of a set screw s which is inserted into a nut thread of the conductive, in the ίο head j attached arm sits t. The arm t is conductively connected by a metal plate t1 to the terminal u, to which the second pole of the energy source is connected. To increase the flywheel mass, a relatively thick, disk-like piece of iron v sits at the outer end of the core armature g. The buffer spring q, the bridge spring h and the piece ν are jointly attached to the core anchor g by a nut v1. As a result of the arrangement of the auxiliary or buffer spring q, the core armature g can perform a longer stroke, while the space between the successive closing and interruption of the circuit is increased, so that the force of the oscillations generated by the inhibition of the core armature vibrations is considerable every time the current is interrupted grows because the core anchor has a greater moment than would otherwise be possible. The core anchor stroke can be achieved by turning its threaded end c by means of the slot located in it with a screwdriver .0. Like. Be regulated. The head of the adjusting screw s is accessible through an opening w2 of the cap η held in its position by screws n1, so that the adjusting screw can easily be adjusted if necessary. It should be noted that the use of an electrical interrupter for the purpose of generating a continuous series of mechanical vibrations for transmission to the body is not new, but the present invention makes it possible to generate vibrations which are devoid of any hardness and are non-irritating, i.e. properties which are practically inseparable from vibrations generated by apparatus in which the armature of the electromagnet acts like a rigid hammer hitting a rigid anvil. The absence of any hardness in the generated vibrations is due, on the one hand, to the buffer effect of the buffer spring q during the movement of the metal masses g and ν in one direction and, on the other hand, to the fact that the core anchor g does not rest on the when the masses move in the other direction Hit the core b of the coil d and the metal mass ν cannot come into contact with the outer pole piece β, since the effect of the masses g and ν is inhibited and canceled by the bridge spring h alone. It can be seen that the stem α of the mushroom-shaped housing is very suitable for insertion into any opening in the body, but the relatively wide and flat cap is more suitable for acting on eyeballs or other limbs where a wider contact surface is desirable. This ability of the instrument to be used reversed or in any position or direction is based on the fact that the entire mass of the housing vibrates intensively, but nevertheless not visibly, as a result of the rapid oscillation of the inner movable masses. The vibrator thus differs from the apparatus in which an external member, fulfilling the function of a hammer, moves in relation to the other parts of the instrument and is consequently only suitable for transmitting the vibrations to the patient's body. The current can be taken from a weak battery w (Fig. 5), which is carried in the pocket and has an off switch w1, so that the vibrator easily undercuts after connecting the terminals u, fi to the poles of the battery by wires u1, ft1 can be used in any circumstance without paying attention to any quotes.
