speaker resonance

speaker resonance

speaker resonance

(OP)
What physically happens at resonance frequency ? Does the speaker oscillate around a nominal position? If yes, does it go on after suppressing the stimulus ?

RE: speaker resonance

Speakers are designed to have very high damping at the resoance frequency or the crossover network and filters are designed to ensure that the speaker does not see any input near its resonant frequency.

The exception is the woofer.  It can receive low frequency signals (bass sounds) and will therefore operate at or near its resonance frequency.

However because they are highly damped (both from the speaker enclosure design) and mechanical damping of the speaker cone, it should only vibrate several more cycles at its resonant frequency after the signal is removed.  That will make a drum beat sound muddy rather than a tight boom.

Hope this helps.
