Dear Sir/madam,

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,

Yours truly,

Hayley Ho
