Abstract

Mehrere Wandlerelemente aus piezoelektrischen Keramikkörpern (13) mit Front- (14) und Rückmasse (10) nach Art eines Tonpilzes werden als Wandleranordnung zusammen auf einenTräger montiert. Um eine federnde Verbindung zwischen Träger und Front- und/oder Rückmasse des Wandlerelements zu vermeiden, weisen alle Wandlerelemente erfindungsgemäß eine gemeinsame Rückmasse mit einem Biegewellenabsorberaufbau (101,102,103) auf, die fest mit dem Träger mechanisch verbunden ist. Der Keramikkörper (13) besteht aus dünnen Keramikscheiben und gewährleistet eine Leistungsanpassung an die speisende Spannungsquelle ohne Anpaßtransformator. Durch einen Vollumguß (17) aus Elastomer ist die Wandleranordnung wasserdicht. Die erfindungsgemäße Wandleranordnung ist mit Vorteil vorzugsweise über Steckverbindungen (18,19) als Stave für eine Zylinderbasis eine Hufeisenbasis oder ebene Basis zum Senden und/oder Empfangen von Schallwellen einsetzbar.

Figure 00000001
Several transducer elements made of piezoelectric ceramic bodies (13) with front (14) and rear mass (10) in the manner of a clay mushroom are mounted together on a carrier as a transducer arrangement. In order to avoid a resilient connection between the carrier and the front and / or rear mass of the transducer element, all transducer elements according to the invention have a common back mass with a flexible shaft absorber structure (101, 102, 103) which is mechanically connected to the carrier. The ceramic body (13) consists of thin ceramic disks and ensures a power adjustment to the supplying voltage source without a matching transformer. The transducer arrangement is watertight due to a full encapsulation (17) made of elastomer. The transducer arrangement according to the invention can advantageously be used, preferably via plug connections (18, 19), as a stave for a cylinder base, a horseshoe base or a flat base for transmitting and / or receiving sound waves.
