Simple, speaker question.
All I want to do is create a very low, and reasonably audible hum or drone from this speaker ; about as loud as a person humming as hard as they can before their throat hurts and they start coughing.
Is it possible to avoid an amplifier and just run a voltage into it so that it just makes a single tone as described ?
I found this big broken speaker in the road.
As you can see, the Cone is missing a section, but the surround and spider are intact.
The cone is credit card thickness plastic.
Is it feasible to just patch it up with some similar plastic and contact adhesive; it does not have to be a good sound, just a drone.
I realise that my grasp of electronics is child like and readily accept the impending abusive comments and links to the Google homepage.
