Diatone was a Japanese subsidiary of Mitsubishi Electric and manufactured loudspeakers and radios. History
In the 1940s, Mitsubishi Electric successfully developed a "hard-ferrite" OP magnet (permanent magnet), laying the foundation for commercial production of magnets based on hard magnetic ferrites. The OP magnet was a key component in Diatone's loudspeaker design. Diatone gained international recognition for the first time.
The first Diatone loudspeaker was developed in 1945 at Mitsubishi Electric's Ofuna factory. Its creation resulted from the recycling of old stock magnets. World War II was over and an understandable shortage of materials made it necessary to make purchases from other manufacturers. At the time, loudspeaker technology had not advanced very far. The production of loudspeakers was very limited.
After supplies improved and strong demand for electronic products began, the prospect of a promising future market, Mitsubishi Electric began to make great strides with comprehensive speaker development. At that time, Mitsubishi Electric obtained innovative technical assistance from the Nippon Hoso Kyokai Technical Research Laboratory. This relationship continued for many years to the benefit of both.
In 1947, Mitsubishi Electric invented the adjustable resonance cone. In combination with an OP magnet, the dynamic loudspeaker P-62 16-Cm-F-type (the forerunner of the P-610) was created. A development that can still be found in loudspeaker design today. In the 1940s, virtually all loudspeaker diaphragms were made of unlined paper and installed together with a cone. Mitsubishi Electric's speakers, on the other hand, used a special paper for the cone made from Japanese washi paper, pressed into a conical shape. This speaker delivered era-defining performance (power handling) for the time.
Although this development was started in 1947, it took until 1950 for the speaker to gain recognition and formal acceptance as a monitor speaker for broadcasting. It was the first step into a market dominated by foreign products. The name Diatone was registered as a trademark in September 1946.
Diatone loudspeakers were used by the Japanese public radio station NHK-Radio as monitor loudspeakers.
Diatone manufactured loudspeakers up to 1.60 m in diameter with the D-160.[1]
Production for radio sets began around 1945 with 4-tube receivers at the factory in Itami, in 1999 the factory was closed.
