Description
Lautsprechendes Telephon. Die Erfindung betrifft ein sehr laut sprechendes Telephon ohne wesentliche Sprach- und Tonverzerrung. Gemäß derselben wird die Schalldose einer normalen Sprechmaschine benutzt, die mit einem von den Sprechströmen betätigten elektromagnetischen oder elektrostatischen System durcli die Schwerkraft oder die Reibung gekoppelt wird. Das die Sprechströme in mechanische Schwingungen umsetzende System beeinflußt unmittelbar den Stift der SprechmaschinenschaUdose.Loudspeaker telephone. The invention relates to a very loud speaker Telephone without significant speech and sound distortion. According to the same, the sound box becomes a normal speaking machine used with one of the speech streams actuated electromagnetic or electrostatic system by gravity or the Friction is coupled. That which converts the speech currents into mechanical vibrations System directly affects the pen of the speaking machine socket.
Zur Erläuterung der Erfindung dient die Zeichnung. Sch ist die Schalldose, H der Hebel, S der Stift und T der Trichter einer Sprechmaschine. A ist der mit einem geeigneten Ansatz versehene Anker eines Elektromagnetsystems. Wenn dieses von Sprechströmen, die beispielsweise durch das MikrophonM und die BatterieB geliefert werden, erregt wird, setzt es dieselben iii mechani5che Schwingungen um, die dadurch auf die Schalldose übertragen werden, daß diese mit dem StiftS auf den Ansatz des Ankers aufgesetzt wird. Das Elektromagnetsystem bildet somit einen Zusatzapparat, der die Benutzung einer vorhandenen Sprechmaschine als Lautsprecher beispielsweise in Verbindung mit einem Radioempfänger gestattet.The drawing serves to explain the invention. Sch is the sound box, H the lever, S the pen and T the funnel of a speaking machine. A is the armature of an electromagnet system provided with a suitable attachment. When this is excited by speech currents, for example supplied by the microphoneM and the batteryB, it converts the same mechanical vibrations that are transmitted to the sound box by placing it with the pinS on the attachment of the armature. The electromagnetic system thus forms an additional device that allows the use of an existing speaking machine as a loudspeaker, for example in connection with a radio receiver.
