ACOUSTIC WAVES IN A RESONANT CAVITY

The resonant frequency depends on the dimensions of the cavity and on the properties of the medium it contains. The magnitude of the displacement of the mylar is very small, so the volume of the cavity may be accurately treated as constant. Think! How

Building Resonance: Structural stability during earthquakes

All buildings have a natural period, or resonance, which is the number of seconds it takes for the building to naturally vibrate back and forth. The ground also has a specific resonant frequency. Hard bedrock has higher frequencies softer sediments. If the period of ground motion matches the natural resonance of a building, it will undergo the largest oscillations possible and suffer the

Resonant Circuits and Soft Switching

Basically, a resonant circuit comprises a coil (L) and a capacitor (C). There are two types of resonant circuits, depending on their topology: parallel and series resonant circuits. At the resonant frequency, parallel resonant circuits have effectively infinite

Inductance, capacitance and resistance

• Resonance is when the frequency is such that a capacitor in series with an inductor cancel each other's reactance. • Similar resonance in a parallel circuit with an inductor and capacitor will have infinite resistance at a resonant frequency.

Understanding Audio Frequency Range in Audio Design

Our blog on resonance and resonant frequency covers this topic in greater detail. When designing an enclosure, you need to ensure that the enclosure itself does not have a natural resonant frequency in the same range as the expected audio output or the speaker itself will have both a non-linear output and unwanted harmonics.

14.4 Sound Interference and Resonance

The phenomenon of driving a system with a frequency equal to its natural frequency is called resonance, and a system being driven at its natural frequency is said to resonate.

15.5 Resonance in an AC Circuit

For example, in radios, the receiver is tuned to the desired station by adjusting the resonant frequency of its circuitry to match the frequency of the station. If the tuning circuit has a high Q, it will have a small bandwidth, so signals from other stations at frequencies even slightly different from the resonant frequency encounter a high impedance and are not passed by the circuit.
