acoustic resonator

The most familiar examples of acoustic resonators are in musical instruments.

Musical instruments use acoustic resonators that produce sound waves of specific tones.

Modeling of acoustic resonators often occurs with equivalent electrical circuits.

Ring-down as a method to interrogate acoustic resonators was established in 1954.

The resonance frequency of acoustic resonators depends on temperature, pressure, and bending stress.

Indeed some of the earliest ideas for filters were acoustic resonators because the electronics technology was poorly understood at the time.

Its form is usually a hollow, cup-shaped acoustic resonator, which vibrates upon being struck.

The exceptionally high Q-factors of acoustic resonators are linked to their weak coupling to the environment.

The resonance is disturbed by the addition or removal of a small mass due to oxide growth/decay or film deposition at the surface of the acoustic resonator.

One application is an RF filter used in mobile phones called a thin film bulk acoustic resonator (FBAR).

For a vibrating component, Agilent replaces Dr. Nguyen's tuned element with a floating internal membrane in what it calls a "film bulk acoustic resonator."

The PAS System uses a special acoustic resonator that is designed to detect an acoustic signal generated by the photoacoustic effect in an open-field.

The exhaust pipes in automobile exhaust systems are designed as acoustic resonators that work with the muffler to reduce noise, by making sound waves "cancel each other out"[1].

A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs (tines) formed from a U-shaped bar of elastic metal (usually steel).

"The paint cans, which are acoustic resonators, amplify the sounds," said Douglas H. Quin, curator of music at the Washington Project for the Arts in Washington, which is sponsoring the concert.

A thin-film bulk acoustic resonator (FBAR or TFBAR) is a device consisting of a piezoelectric material sandwiched between two electrodes and acoustically isolated from the surrounding medium.

The film bulk acoustic resonator was made of piezoelectric material, so that as it oscillated its changing shape created a changing electric signal, and conversely an electric signal could affect its oscillations.

The engine has twin balance shafts and specially designed cam cover to improve NVH, while optimized compressor geometry, acoustic resonators and overall air handling help reduce noise by 2 dB.

RF & Microwave - Including Thin Film Bulk Acoustic Resonator (FBAR) filters, GPS filter-LNA module, and Power Amplifiers for mobile phones.

Two main variants of BAW filters are making their way into devices, Thin film bulk acoustic resonator or FBAR and Solid Mounted Bulk Acoustic Resonators.
