All sound transducers and absorbing/reflecting surfaces have a natural resonant frequency depending on their mass and compliance, which is analogous to the resonant frequency of an LC circuit. The natural resonant frequency of a mechanical system like a mass on a spring is given by the same equation as the resonant frequency of an LC circuit: f = 1/2π√(k/M), where k is the spring constant, M is the mass, and f is the resonant frequency.

2. Basics
 All sound transducers have mechanical parts capable of
vibrating.
 All these systems have a natural resonant frequency
depending on its mass and compliance of the vibrating system.
 Similarly, the absorbing and reflecting surfaces can have a
natural resonant frequency.

3. Mechanical to Electrical Analogy
In LC oscillation, natural resonant frequency is given by
 So, If we go by Force voltage analogy, to translate mechanical coordinate to
electrical and visa versa.
 So as per force to voltage analogy, mass M is equivalent to inductance L
and spring constant k is equivalent to 1/C capacitance. So natural resonance
is given by
