What component did Jaap C. Haartsen's invention specifically NOT include?
Answer
The physical cone or magnet of the speaker unit
While Haartsen invented the technology that allowed the audio file to travel wirelessly to a speaker, the text makes a clear distinction that his contribution was the connection standard, not the physical apparatus that generates sound. His work covered the digital handshake and the wireless link, but it did not cover the physical aspects of speaker design, such as the enclosure, the magnets used for transduction, or the cone material itself. These physical elements of sound production predate the standardized wireless transmission method he developed.
