Model:

This is a replica model with accurate measurements from a real product.

It's rigged using an armature and ready to be animated.

You can animate the cone movements of both speakers individually and all of the buttons.

All of the objects make use of the Subdivision Modifier.

Addon:

Stereo Speakers Auto-Animator is a tool that allows you to automatically generate keyframes by directly importing frames from the waveform of an audio file.

This addon's purpose is to mostly aid in animating the drivers from stereo speaker systems, however, it's versatile enough to be used in varied ways, specially when applied to geometry or material nodes.
