The term tonpilz or "acoustic mushroom" may refer to a certain type of underwater electro-acoustic transducer. By sandwiching active (i.e. piezoelectric or magnetostrictive) materials between a light, stiff radiating head mass and a heavy tail mass, the transducer can effectively operate as either a projector (source) or a hydrophone ...

The tonpilz (sound mushroom) piezoelectric transducer is a transducer for relatively low frequency, high power sound emission. The transducer consists of piezoceramic rings stacked between massive ends and pre-stressed by a central bolt.

To achieve a desired sound pressure level (SPL) and beam pattern, twelve Tonpilz transducers in a dual-array configuration, with one array of seven and the other with five transducers was assembled.

Dec 1, 2021 · This paper describes the designing and optimization of tonpilz type transducers based on number of layers, width and thicknesses and type of active materials, dimensions of head and tail mass by exploiting finite element models for their effective and optimized usage in underwater SONAR applications.

In this study, a simple design is proposed to improve the bandwidth of a multimode Tonpilz transducer by using a non-uniform drive section that consists of piezoelectric stacks of various thicknesses.

Mar 20, 2025 · Tonpilz acoustic emission transducers offer advantages such as high power, stable performance, easy array deployment, compact size, and high sensitivity. These features make them widely used in various fields, including underwater communication, positioning and navigation, marine resource assessment, and unmanned underwater vehicle (UUV) search ...

In contrast to the horn that leverages the Langevin’s energy into a high vibrational velocity tip for mechanical work, the Tonpilz transmission scheme is aimed at getting 100% of the Langevin’s output into broadcasting acoustic waves from one end and 0% off the other.

The tonpilz transducer is one of the most popular types of sonar transducer, and its low cost, simplicity, and good performance are well known. The typical con- guration of a tonpilz transducer is shown in Fig. 1.

A tonpilz transducer, such as the one shown in Figure 1, is used for relatively low frequency, high power sound emission. It is one of the popular transducer configurations for sonar applications.

Jul 1, 2019 · Low-medium frequency Tonpilz-type transducers are highly important for underwater sonar technologies to generate and receive sound waves. This study covers designing, manufacturing and characterization of Tonpilz-type transducers which is intended to be used in currently-utilized hull mounted sonar systems.
