Candlestick Telephone
The candlestick telephone (or pole telephone) is a style of telephone that was common from the late 1890s to the 1940s. A candlestick telephone is also often referred to as a desk stand, an upright, or a stick phone. Candlestick telephones featured a mouth piece (transmitter) mounted at the top of the stand, and a receiver (ear phone) that was held by the user to the ear during a call. When the telephone was not in use, the receiver rested in the fork of the switch hook protruding to the side of the stand, thereby disconnecting the audio circuit from the telephone network. Design and features Candlestick telephones were designed with varying features. Most recognizable, candlesticks featured a base with a vertical cylindrical neck extending upright for up to in length. At the top of the stand was mounted a carbon microphone (''transmitter'') to speak into, and a switch hook extending sideways upon which an ear piece (''receiver'') was hung. To make or answer a telephone call, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Shack
RadioShack, formerly RadioShack Corporation, is an American retailer founded in 1921. At its peak in 1999, RadioShack operated over 8,000 worldwide stores named RadioShack or Tandy Electronics in the United States, Mexico, United Kingdom, Australia, and Canada. Outside of those territories, the company licensed other companies to use the RadioShack brand name in parts of Asia, North Africa, Latin America, and the Caribbean.

Ericofon
The Ericofon is a one-piece plastic telephone created by the Ericsson Company of Sweden and marketed through the second half of the 20th century. It was the first commercially marketed telephone to incorporate the dial and handset into a single unit. Because of its styling and its influence on future telephone design, the Ericofon is considered one of the most significant industrial designs of the 20th century by Phaidon. It is in the collection of the Museum of Modern Art in New York City. In Sweden, the Ericofon is known as the cobra telephone for its resemblance to a coiled snake. History The Ericofon was designed in the late 1940s by a design team including Gösta Thames, Ralph Lysell, and Hugo Blomberg. The two major components of the telephone, the handset and the dial, are combined in a single unit. This one-piece design anticipated the evolution of the typical cordless phone and cell phone by several decades. Serial production began in 1954. Early models were sold only ...

Megaphone
A megaphone, speaking-trumpet, bullhorn, blowhorn, or loudhailer is usually a portable or hand-held, cone-shaped acoustic horn used to amplify a person's voice or other sounds and direct it in a given direction. The sound is introduced into the narrow end of the megaphone, by holding it up to the face and speaking into it, and the sound waves radiate out the wide end. A megaphone increases the volume of sound by increasing the acoustic impedance seen by the vocal cords, matching the impedance of the vocal cords to the air, so that more sound power is radiated. It also serves to direct the sound waves in the direction the horn is pointing. It somewhat distorts the sound of the voice because the frequency response of the megaphone is greater at higher sound frequencies. Since the 1960s the voice-powered ''acoustic megaphone'' described above has been replaced by the ''electric megaphone'', which uses a microphone, an electrically-powered amplifier and a folded horn loudsp ...

Hush-A-Phone
''Hush-A-Phone v. United States'', 238 F.2d 266 (D.C. Cir. 1956) was a seminal ruling in United States telecommunications decided by the D.C. Circuit Court of Appeals. Hush-A-Phone Corporation marketed a small, cup-like device which mounted on the speaking party's microphone, reducing the risk of conversations being overheard and increasing sound fidelity for the listening party. At the time, AT&T had a near-monopoly on America's phone system, even controlling the equipment attached to its network. In this era, Americans had to lease equipment from " Ma Bell" or use approved devices. At this time Hush-A-Phone had been around for 20 years without any issues. However, when an AT&T lawyer saw one in a store window, the company decided to sue on the grounds that anything attached to a phone could damage their network. AT&T, citing the Communications Act of 1934, which stated in part that the company had the right to make changes and dictate "the classifications, practices, and regula ...

Sidetone
Sidetone is audible feedback to someone speaking or otherwise producing sound as an indication of active transmission. Sidetone is introduced by some communications circuits and anti-sidetone circuitry is used to control its level. Sidetone is expected behavior for telephone systems. Absence of sidetone can cause users to believe the call has been dropped or cause them to speak loudly. Too much sidetone can cause users to speak softly. Telephony In telephony, sidetone is the effect of sound picked up by the telephone's transmitter (mouthpiece) and instantly introduced at a low electronic signal level into the receiver (earpiece) of the same handset, a form of electrical feedback through the telephone hybrid.AT&T, ''Bell System Practices'', Section C30.001 Issue 1 (March 16, 1932) ''Common Battery Anti-Sidetone Stations'' Sidetone in early 19th century telephones was strong due to the type of circuit used in instruments. Anti-sidetone circuitry in the telephone hybrid brought sideto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model 202 Telephone
The Western Electric hand telephone sets comprise a series of telephones that were produced from 1927 by the Western Electric Company for the American Telephone and Telegraph Company (AT&T) and the Bell System. The series features the mouthpiece (''transmitter'') and the earpiece (''receiver'') combined into a hand-held unit, originally named a ''hand telephone'', or ''handset''. The handset would be held against the ear and in front of the mouth simultaneously, in contrast to earlier telephones in the Bell System where only the receiver was held against the ear, while the user spoke into a fixed transmitter mounted on a telephone stand or wall telephone. Hand telephone sets consist of three principal parts: the ''handset'', a ''handset mounting'', and an apparatus box, called variously ''desk set box'', ''bell box'', ''subscriber set'', or just ''subset''. This box is typically mounted on a wall or desk-side, and contains an electromagnetic bell ringer and a speech transformer, ...

Retro
Retro style is imitative or consciously derivative of lifestyles, trends, or art forms from history, including in music, modes, fashions, or attitudes. In popular culture, the "nostalgia cycle" is typically for the two decades that begin 20–30 years ago. Definition The term ''retro'' has been in use since 1972 to describe on the one hand, new artifacts that self-consciously refer to particular modes, motifs, techniques, and materials of the past. But on the other hand, many people use the term to categorize styles that have been created in the past. Retro style refers to new things that display characteristics of the past. Unlike the historicism of the Romantic generations, it is mostly the recent past that retro seeks to recapitulate, focusing on the products, fashions, and artistic styles produced since the Industrial Revolution, the successive styles of Modernity. The English word ''retro'' derives from the Latin prefix ''retro'', meaning backwards, or in past times. In Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
