Abstract:

The invention relates to a signal horn upon which external influences have an effect which is as minor as possible. The inventive signal horn comprises a control circuit for adaptively modifying an operating variable in order to bring it into line with a predefinable set-point value. A switch (6);controlled by a pulse generator (6); is used to control an excitation current (I) flowing through the signal horn in relation to the pulse frequency and/or pulse-scan ratio. Switching means (11) which detect one or several characteristic variables of the excitation current (I) are provided, in addition to other switching means (12) which provide one or several manipulated variables for the pulse generator (6) from the deviation between the characteristic variable(s) derived from the excitation current (I) and one or several set-point values.
