Abstract

Die Erfindung betrifft einen Schallwandler (10), mit einem Abzweigungsglied (11,11',11''), das mit einer Abgasanlage einer Brennkraftmaschine (1), insbesondere eines Kraftfahrzeuges, zur Abzweigung von Abgaspulsationen verbunden ist, und mit einem Schallwandlerkopf (15,15a,15b,15c), über den basierend auf den Abgaspulsationen Luftschall zumindest in den Raum der Brennkraftmaschine abstrahlbar ist.

Figure 00000001
The invention relates to a sound transducer (10) with a branching element (11, 11 ', 11'') which is connected to an exhaust system of an internal combustion engine (1), in particular a motor vehicle, for branching off exhaust gas pulsations, and with a sound transducer head (15 , 15a, 15b, 15c), via which airborne sound can be radiated at least into the space of the internal combustion engine based on the exhaust gas pulsations.
