  2. Electromagnetic acoustic transducer - Wikipedia

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

    Using piezoelectric transducer, the wave propagation angle in the test part is affected by Snell's law. As a result, a small variation in sensor deployment may cause a significant change in the refracted angle. Easier to generate SH-type waves. Using piezoelectric transducers, SH wave is difficult to couple to the test part.

  3. Enhanced Acoustic Simulator for Engineers - Wikipedia

    en.wikipedia.org/wiki/Enhanced_Acoustic...

    Enhanced Acoustic Simulator for Engineers (EASE) is an engineering design and analysis software for optimizing acoustics. [1] The full product is licensed and copy protected. It can perform complex analysis in three-dimensional space. There is a free-to-use web-based version available for two-dimensional analysis with limited geometry options. [2]

  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. 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 ...

  6. Fessenden oscillator - Wikipedia

    en.wikipedia.org/wiki/Fessenden_oscillator

    A Fessenden oscillator is an electro-acoustic transducer invented by Reginald Fessenden, with development starting in 1912 at the Submarine Signal Company of Boston. [1] It was the first successful acoustical echo ranging device.

  7. 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.

  8. Electrodynamic speaker driver - Wikipedia

    en.wikipedia.org/wiki/Electrodynamic_speaker_driver

    This loudspeaker enclosure or speaker box isolates the acoustic energy from the front of the cone from that of the back of the cone. A horn may be employed to increase efficiency and directionality. A grille , fabric mesh , or other acoustically neutral screen is generally provided to cosmetically conceal the drivers and hardware, and to ...

  9. Air Motion Transformer - Wikipedia

    en.wikipedia.org/wiki/Air_Motion_Transformer

    The Air Motion Transformer (AMT) is a type of electroacoustic transducer.Invented by Oskar Heil (1908–1994), it operates on a different transduction principle from other loudspeaker designs, such as moving coil, planar magnetic or electrostatically-driven loudspeakers, and should not be confused with planar or true ribbon loudspeakers.
