Description

Elektrodynamischer Lautsprecher Bei den in neuerer Zeit verwendeten elektrodynamischen Lautsprechern wird zur Erregung des Systems eine Wicklung an ein Gleichstromlichtnetz oder an einen gleichgerichteten Wechselstrom angeschlossen.Electrodynamic loudspeaker Among those used in recent times electrodynamic loudspeakers, a winding is used to excite the system a direct current lighting network or connected to a rectified alternating current.

Die Erfindung geht nun von dem Gedanken aus, diese an sich vorhandene Einrichtung noch zu einem anderen Zweck auszunutzen, und zwar als Teil eines Netzanschlußgerätes. Zu diesem Zweck wird erfindungsgemäß die Erregerwicklung des elektrodynamischen Lautsprechers mit Anzapfungen versehen, so daß sie dadurch zugleich als Spannungsteiler dient. Es wird also mit dieser Einrichtung der Vorteil erzielt, daß man an der Erregerwicklung die verschiedenen Gleichspannungen abgreifen kann, ohne hierfür einen besonderen Spannungsteiler im Netzanschlußgerät verwenden zu müssen. Die sonst bei Netzanschlußgeräten üblichen Kapazitäten, Drosselspulen und Vorschaltwiderstände sind ebenfalls erforderlich, also auch die in an sich bekannter Weise zwischen den Anzapfungen eines Spannungsteilers liegenden Ausgleichskapazitäten. Auch ist es vorteilhaft diese Apparateteile gleichzeitig mit in dem Gehäuse des elektrodynamischen Lautsprechers unterzubringen. Dadurch wird der Vorteil erzielt, daß ein Zusammenfassen des Netzanschlußgerätes mit dem Lautsprecher erfolgt und nur ein Netzanschluß nötig ist. Die Spannungen lassen sich unmittelbar von den Steckanschlüssen, die an dem Lautsprechergehäuse vorgesehen sind, abgreifen.The invention is based on the idea that this is present in itself To use the facility for another purpose, namely as part of a power supply unit. For this purpose, according to the invention, the excitation winding of the electrodynamic The loudspeaker is provided with taps so that it also functions as a voltage divider serves. So it is achieved with this device, the advantage that you can work on the excitation winding can tap the various DC voltages without having to use a special one To have to use voltage divider in the power supply unit. The otherwise with power supply units Usual capacities, reactors and series resistors are also required, thus also in a manner known per se between the taps of a voltage divider lying compensation capacities. It is also advantageous to have these parts of the apparatus at the same time to be accommodated in the housing of the electrodynamic loudspeaker. Through this the advantage is achieved that a combination of the power supply unit with the Loudspeaker takes place and only a power connection is necessary. The tensions let go directly from the plug connections provided on the loudspeaker housing are, tap.
