Description

T e l e f o n v e r s t ä r k e r Die Erfindung bezieht sich auf einen Telefonverstärker, der vom Fernsprechgerät getrennt in einem eigenen Gehäuse angeordnet ist. T e l e f o n v e rstärk e r The invention relates to a telephone amplifier, which is separated from the telephone device in its own housing is arranged.

Bekannte Geräte dieser Art sind mit einem Lautsprecher ausgestattet, der das in dem Fernsprechgerät ankommende Gespräch verstärkt hörbar macht.Well-known devices of this type are equipped with a loudspeaker, which makes the incoming call in the telephone set audible.

Ein Nachteil dieser bekannten Ausführungsform besteht darin, dass die Verstärkung besonders bei Gesprächen über weite Entfernungen nicht mehr ausreichend ist, weil, noch ehe der gewünschte Verstärkungsgrad erreicht wird, eine unliebsame akustische Rückkopplung einsetzt.A disadvantage of this known embodiment is that the reinforcement is no longer sufficient, especially when talking over long distances is because, before the desired level of gain is reached, an unpleasant one acoustic feedback sets in.

Der Neuerung liegt der Gedanke zugrunde, diesen Nachteil zu beseitigen und das ankommende Gespräch wahlweise über den Lautsprecher und/oder über einen Kopf-bezw. Ohrhörer erheblich verstärkt zu übertragen.The innovation is based on the idea of eliminating this disadvantage and the incoming call either via the loudspeaker and / or via a Head or Transmit earphones significantly amplified.

Der Betrieb bei Telefonverstärkern gemäss Erfindung kann also wechselweise und gleichzeitig über Lautsprecher bezw. Kopf-oder Ohrhörer erfolgen.Operation in telephone amplifiers according to the invention can therefore alternate and at the same time via loudspeaker respectively. Headphones or earphones can be made.

Im nachstehenden wird ein Ausführungsbeispiel des Gegenstandes der Erfindung unter Bezugnahme auf die Zeichnung näher beschrieben.In the following an embodiment of the subject matter of Invention described in more detail with reference to the drawing.

Es zeigen : Fig. 1-einen Telefonverstärker in beispielhafter Ausführung und in perspektivischer Darstellung ; Fig. 2-die Anordnung der Lautsprechers im Gehäuse, zusammen mit der Steckvorrichtung für einen Ohrhörer und den daran angeschlossenen Ohrhörer.1 shows an exemplary embodiment of a telephone amplifier and in a perspective view; Fig. 2-the arrangement of the loudspeakers in Housing, together with the connector for an earphone and the connected to it Earphones.

Das in Figur 1 gezeigte Gerät mit einem Gehäuse aus beliebigem Material zeigt den Lautsprecher 1, den Lautstärkeregler 2 und das Anschlusskabel für den Telefonapparat 3, sowie das Tastenaggregat für Ein-und Ausschaltung 4.The device shown in Figure 1 with a housing made of any material shows the loudspeaker 1, the volume control 2 and the connection cable for the Telephone set 3, as well as the key unit for switching on and off 4.

Figur 2 zeigt in Form eines Schnittes die Anordnung des Lautsprechers 1 und eine Steckvorrichtung 5 für die Aufnahme eines Steckers 6 an der Zuleitung zu einem Kopf-bezw. Ohrhörer 7.FIG. 2 shows the arrangement of the loudspeaker in the form of a section 1 and a plug device 5 for receiving a plug 6 on the supply line to a head or Earbuds 7.

In der beispielhaft gezeigten Ausführung wird bei Einstecken des Ohrhörers der Lautsprecher abgeschaltet.In the embodiment shown as an example, when the earphone is plugged in the loudspeaker is switched off.

Natürlich fällt es in den Rahmen der Erfindung, wenn man beispielsweise Lautsprecher und Ohr-bezw. Kopfhörer gleichzeitig betreiben würde.Of course, it falls within the scope of the invention if, for example Loudspeaker and ear or Headphones would operate at the same time.

Ferner zeigt das Ausführungsbeispiel eihen Ohrhörer, was aber nicht die Reichweite der Erfindung einengen soll, denn ebensogut könnte man einen Kopfhörer nehmen.Furthermore, the embodiment shows an earphone, but what not to narrow the scope of the invention, because you could just as well use headphones to take.

Schliesslich ist noch zu bemerken, dass die Form und Konstruktion des Gehäuses, wie es in der Zeichnung gezeigt wird, die Reichweite der Erfindung nicht einengen soll.Finally, it should be noted that the shape and construction of the housing as shown in the drawing, the scope of the invention should not constrict.

Ein derartiger Telefonverstärker ist in den verschiedensten Formen und Konstruktionen des Gehäuses möglich.Such a telephone amplifier is in the most varied of forms and constructions of the housing are possible.
