I am doing a project on the loudspeaker for a design and technology
coursework. I have to find out how it works where and why it was invented,
what materials they are made of and why, and the production methods involved
in producing this product. If you are able to provide me with diagrams of the
inside of the loudspeaker, or provide me with any good web sites and
information, I would be very grateful.
Thankyou for your time,
