RE: Read The Patent.

Posted by DrChaos on March 2, 2017 at 23:21:56:
That stuff is illustrative but has no legal force. Only the claims matter:
Clam 1, in totality: "A speaker comprising: a transducer configured to reproduce a sound generated by a moving and sound-generating portion of a musical instrument, the transducer comprising a moving element, wherein the moving element is limited in mass to approximate the mass of the moving and sound-generating portion of the musical instrument."
As written, it's super vague, and either covers nothing, or almost all speakers.
How do you determine if a transducer is "configured to reproduce a sound generated by a moving and sound-generating portion of a musical instrument"?
What is the 'sound generating portion of the musical instrument'? Let's take a clarinet. Is this the reed? Or the body of the clarinet? Or the mass of the air inside
What about a piano? Is this mass the string? What about the hammer, that's pretty important to the sound-generating, and it moves. What about the wood body, that's also important to making the sound. Which mass is this?
If you find a transducer of mass x and an instrument with 'sound generating portion' of nearly mass 'x', and you can play that sound through the transducer, does the patent cover it?
If so, it would cover all speakers, just need to find one instrument to match a transducer's mass.
Or it covers nothing because speakers aren't "configured" to reproduce a sound generated by a musical instrument, they are configured to reproduce an electrical signal in sound pressure.
