Description
Das Patent 336088 betrifft eine Einrichtung, bei welcher ein Mikrophon eines mit einer Membran versehenen Schallempfängers mit dieser Membran oder sonstigen zwischen ihr und dem Mikrophon vorhandenen Schwingungsgebilden durch rohrartige, ineinandergeschobene Körper erheblichen Querschnitts und geringer Höhe verbunden ist.The patent 336088 relates to a device in which a microphone has one a membrane provided sound receiver with this membrane or other between you and the microphone existing vibration structures through tubular, nested Body of considerable cross-section and low height is connected.
Die vorliegende Erfindung betrifft eine weitere Ausbildung einer derartigen Einrichtung, die insbesondere den Zweck verfolgt, die Festigkeit der Verbindung der einzelnen Teile der Kopplungsvorrichtung untereinander und mit den angrenzenden Teilen gegenüber Zugbeanspruchungen zu erhöhen. Die Erfindung besteht zunächst darin, daß die ineinandergefügten Kopplungsglieder, also beispielsweise die rohrartigen Teile, derart konisch ausgebildet oder mit Einschnürungen versehen sind, daß sie von der Membran aus nach dem Detektor (Mikrophon) zu oder in umgekehrter Richtung sich in ihrem Querschnitt verjüngen. Dadurch wird einmal erreicht, daß durch das Anziehen derThe present invention relates to a further embodiment of such a device, which in particular pursues the purpose of ensuring the strength of the connection between the individual Parts of the coupling device with each other and with the adjacent parts opposite To increase tensile loads. The invention consists first in that the nested coupling members, thus for example the tubular parts, designed in such a conical manner or with constrictions are provided that they move from the membrane to the detector (microphone) or in the opposite direction taper their cross-section. This once achieved that by tightening the
as auf dem äußeren Kopplungsteile befindlichen Klemmvorrichtung sämtliche inneren Kopplungsteile aneinander herangeholt werden, wodurch eine bessere und festere dauernde Verbindung zwischen den zusammenwirkenden Gebilden hervorgebracht wird. Weiterhin wird eine Erhöhung der Festigkeit der Kopplung gegen in Richtung ihrer Längsachse wirkende Zugbeanspruchung erzielt und mit Sicherheit verhindert, daß die ineinandergesteckten Teile durch derartige Kräfte auseinandergezogen werden. Weiterhin besteht die Erfindung darin, daß die an den übrigen Bestandteilen des Empfängers (beispielsweise an dem Detektor) angreifenden Teile der Kopplungsvorrichtung durch Verschrauben oder Ineinanderfalzen o. dgl. derart mit diesen verbunden sind, daß sie sich Zugbeanspruchungen gegenüber gegenseitig" sperren.as located on the outer coupling parts Clamping device all inner coupling parts are brought together, whereby a better and stronger permanent connection between the cooperating Forms is produced. Furthermore, an increase in the strength of the Coupling achieved against tensile stress acting in the direction of its longitudinal axis and certainly prevents the nested parts from being affected by such forces be pulled apart. Furthermore, the invention consists in that the to other components of the receiver (for example on the detector) attacking Parts of the coupling device by screwing or folding into one another or the like are connected to these that they are mutually resistant to tensile stresses " lock.
In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt.In the drawing, an embodiment of the invention is shown as an example.
Es bezeichnet 1 die Membran eines Schallempfängers, 2 das Mikrophon, 3 einen äußeren, rohrförmigen Körper des Verbindungsgliedes, 4 einen inneren, ebenfalls rohrförmigen Körper, 5 einen geschlitzten Ring aus Isoliermaterial, welcher beide Körper voneinander trennt, und 6 eine Schelle zur Zusammenziehung des äußeren Kupplungsteiles.It denotes 1 the diaphragm of a sound receiver, 2 the microphone, 3 an outer, tubular body of the connecting member, 4 an inner, likewise tubular body, 5 a slotted ring of insulating material, which separates the two bodies, and 6 a clamp for contracting the outer one Coupling part.
Der Teil 4 ist, wie aus der Zeichnung ersichtlich, mit seiner Kröpfung in den BodenThe part 4 is, as can be seen from the drawing, with its offset in the ground

des Mikrophons 2 eingefalzt. Diese Maßnahme dient ebenfalls zur Erhöhung der Festigkeit der Einrichtung gegen Zttgbeanrspruchungen, da es leicht vorkommen kann, daß bei einfachem Auflöten oder Aufkleben dieses Teiles auf den Boden des Mikrophons letzteres von dem Verbindungsglied abreißt. Die Steigung der Seitenlinie des Konus bzw. der Pyramide kann steiler sein, wie sie in der Zeichnung dargestellt ist. Es genügt ein Neigungswinkel von wenigen Graden ge-, gen die Längsachse. Die Grenze ist in der Regel dadurch gegeben, daß der äußere und der innere Teil der Befestigungsvorrichtung bequem ineinanderschiebbar sein müssen.of the microphone 2 folded in. This measure also serves to increase the Resistance of the device to tensile stresses, because it can easily happen that with simple soldering or gluing this part to the bottom of the microphone tears the latter off the connecting link. The slope of the side line of the cone or pyramid can be steeper, as they are is shown in the drawing. An angle of inclination of a few degrees is sufficient, gen the longitudinal axis. The limit is usually given by the fact that the outer and the inner part of the fastening device must be conveniently telescopic.
