What is a transistor radio?
Transistor radio is a compact, portable radio that uses a transistor radio receiver to receive and amplify radio sound waves. The development of the transistor radio at the end of the 1940s and 1950s revolutionized radio electronics. Previously, all types of radio consisted of fragile glass vacuum pipes located in large, heavy and cumbersome cases. This radio consists of a small, solid status semiconductor chip that receives and amplifies sound waves from radio stations and other broadcasting devices. Thanks to the small size of the transistor radio associated with its durability and long battery life, the device made the first portable radio that affected modern culture and the development of smaller, faster electronic devices.
After World War II, scientists and electronic developers were looking for ways to improve radio and radar communication for the United States Army. Scientists in Bell Labs have developed a unique set of semiconductors consisting of SENdvičs from Germania crystals and metal. These interconnected semiconductors, called transistor, accepted and transmitted radio waves to larger capacity AS greater clean than the vacuum tube device. This new technology has created the development of modern telephony and computers, but has not yet been a large -scale consumer for several years.
In 1954, Regency Electronics and Texas Instruments transistor incorporated into the first portable transistor radio. Radio Regency TR-1 was a slim five-inch tall, plastic boxes with a large round radio dial and smaller volume dialing. Regency sold transistor radios in various colors and consumers invented radios within months. However, American radio companies slowly adopted these radios into mass production. The Japanese company called Tokyo Tsushin Kogyo filled the vacuum for the production of transistor radio. Changing their name Subject to send outThe villa more pronounced Sony, which has devoted its entire production to American consumers to create transistor radios.
Transistor radio has created messages, information and music immediately mobile. Small radio fits perfectly in your pocket and 22.5 V (22.5 W/Ampre) has expanded almost 24 hours. American society was prepared for transistor radio: Prosperity and one -off income after World War II grew to exponentially high levels and population explosions and the interest in faster and more efficient devices and devices grew with it. Most importantly, young Americans with a greater consumer influence found that this radio provided them with more liberal music separated from a traditional family vacuum tube and created an era of modern rock music.
While transistor radios eliminated for later development, such as boom boxes 80.Radio as the head of a modern electronic age. Microsoft founder Bill Gates pointed to transistor as the predecessor of a personal computer. Fortune The magazine claimed that the transistor was "the most important invention of the 20th century". This radio, as small as it was, also embodied the massive postwar power of the American consumer.
