  2. Electromagnetic acoustic transducer - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_acoustic...

    An electromagnetic acoustic transducer (EMAT) is a transducer for non-contact acoustic wave generation and reception in conducting materials. Its effect is based on electromagnetic mechanisms, which do not need direct coupling with the surface of the material.

  3. Exciter (audio transducer) - Wikipedia

    en.wikipedia.org/wiki/Exciter_(audio_transducer)

    An Exciter is an electroacoustic transducer. [1] Exciters differ from the more common loudspeaker in that they have no cone and rely on being connected to a surface or object that can be used as a resonator via a mechanical connection. They have been used in several projects with novel resonators [2] and are readily available from several supplies.

  4. Acoustical measurements and instrumentation - Wikipedia

    en.wikipedia.org/wiki/Acoustical_measurements...

    Data acquisition hardware for acoustic measurements typically utilizes 24-bit analog-to-digital converters (ADCs), anti-aliasing filters, and other signal conditioning. This signal conditioning may include amplification, filtering, sensor excitation, and input configuration. Another consideration is the frequency range of the instrumentation.

  5. Tonpilz - Wikipedia

    en.wikipedia.org/wiki/Tonpilz

    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 (underwater acoustic receiver).

  6. Interdigital transducer - Wikipedia

    en.wikipedia.org/wiki/Interdigital_transducer

    An interdigital transducer (IDT) is a device that consists of two interlocking comb-shaped arrays of metallic electrodes (in the fashion of a zipper). These metallic electrodes are deposited on the surface of a piezoelectric substrate , such as quartz or lithium niobate , to form a periodic structure.

  7. Acousto-electronics - Wikipedia

    en.wikipedia.org/wiki/Acousto-electronics

    The term 'acousto-electronics' is often understood in a wider sense to include numerous practical applications of the interactions of electro-magnetic fields with acoustic waves in solids. In particular, these are signal processing devices using surface acoustic waves (SAW), different sensors of temperature, pressure, humidity, acceleration, etc.

  8. Category:Transducers - Wikipedia

    en.wikipedia.org/wiki/Category:Transducers

    A transducer is a device, usually electrical, electronic, electro-mechanical, electromagnetic, photonic, or photovoltaic that converts one type of energy to another for various purposes including measurement or information transfer (for example, pressure sensors). In a broader sense, a transducer is sometimes defined as any device that converts ...
