The audio port, commonly known as the headphone jack or audio jack, does not have a single inventor. Its development is attributed to several innovations in audio technology over the years, particularly the 1/4-inch (6.35 mm) and 1/8-inch (3.5 mm) connectors that became standard in the mid-20th century. The 3.5 mm audio jack, which is widely used today, was popularized by companies like Sony in the 1970s.
