). Dopyera had seen an amplified Stroh stick violin nearby with a small flat diaphragm and long attached horn. He used that initial idea, but with a large spun conical inverted speaker to create his patented multiple resonator designs. Dopyera was assisted with his nephews Paul and Carl Barth spinning the first aluminum diaphragms on wooden bucks. They first experimented with their novel ampli-phonic design in a large walnut console instrument. Soon afterwards the first German silver Hawaiian guitar was built by John and Rudolph Dopyera. This guitar, #101 was later modified with a mahogany Spanish neck for regular guitar playing. Beauchamp had suggested to Dopyera the need for a guitar loud enough to play a melody over brass and other wind instruments. In 1927, National produced the first resonator instruments and sold them under their ''National'' brand. They had metal bodies and a ''tricone'' resonator system, with three aluminium cones joined by a T-shaped aluminium ''spider''. Brother Rudolph Dopyera, who previously worked with Weissenborne, hand built the original tri-cone models with diamond holes, prior to the second production stamped metal bodies by engineer Adolph Rickenbacher. They built metal resophonic mandolins, tenor guitars and ukuleles, some of which were ornately engraved with rose, lily of the valley and chrysanthemum designs. Wooden-bodied Triolian and Trojan single resonator models eventually followed once the Dopyera brothers departed, based on inexpensive

Dobro

In 1928, Dopyera left National, and with four of his brothers formed the Dobro Manufacturing Company to produce a competing single resonator design, with the resonator cone inverted. John Dopyera continued to hold stock in National. The ''Dobro'' design was both cheaper to produce and louder than the tricone. National soon introduced their own single resonator design, the "biscuit", which Dopyera claimed to have designed before leaving, though the patent was registered by Beauchamp. National also continued to produce tricone designs, which some players preferred. In their 1930 catalog, National list eight key ''associates'', including
