The Regency model TR-1 contained four transistors. Texas Instruments Designs the Regency TR-1, the First Commercial Transistor Radio, and the First Widely Sold Tranistorized Product.
TRANSISTOR RADIO PORTABLE
Work began in earnest in the spring of 1954, and this first Regency transistor radio was in stores for the Christmas season later that year.

Planning began in 1951 between Idea and Texas Instruments, supplier of the transistors. In 1994 Saro-Wiwa was imprisoned by order of the dictator Sani Abacha. The modern radio uses transistor since it is smaller in size. Nigerian television producer, writer of satirical novels, childrens tales, and plays. Radio is a device which transmit and amplifies signals. In 1953 hearing aids became the first commercial product to use transistors.Ī small, portable radio seemed a good opportunity, and a company called Idea Incorporated designed and produced the Regency. What is the difference between transistor and radio A transistor is a semiconductor device used in electronic circuits as to function as on and off switching and amplifying device in the electronic circuits.
TRANSISTOR RADIO HOW TO
As engineers learned how to use the new invention, plans were made for commercial products that could take advantage of the transistor's small size, energy efficiency, and rugged design.
TRANSISTOR RADIO LICENSE
Bell publicly announced the new invention on 30 June 1948.Īt first the US military bought all the transistors Bell Labs could make, and the company agreed to license other manufacturers. AM FM Battery Operated Portable Pocket Radio - Best Reception and Longest Lasting. Generally, the most collectable and historic transistor radios are those made in Japan from 1956 to 1963 and America from 1955-60. The first laboratory demonstration took place on 23 December 1947. Transistor Radio(1000+) AM FM Radio - Best Reception and Longest Lasting. Building on war-time research, John Bardeen and Walter Brattain, working with group leader William Shockley, developed a device they called a transistor. By the end of the 1960s, the transistor radio helped people throughout the world keep in touch with news and opinions. One goal was to find a replacement for fragile and energy-wasting vacuum tubes.
