Abstract

Bei einem akustoelektrischn Wandler mit einem Spulen­ windungen tragenden Tragkörper, insbesondere einem in sich schwingenden Hohlkörper mit gekrümmter Oberfläche, wie einer magnetostriktiven Kugel wird insbesondere zur Erzielung einer optimalen Verteilung der Modulations­ energie vorgeschlagen, daß die Spule als ein quer zur Laufrichtung in sich gewelltes Band (3) aus Flachmaterial auf den Tragkörper (2) aufgelegt ist.
