Timeline Of The Telephone ... It is disputed if this is an electromagnetic telephone, but is said to involve direct transmission of electricity into the user's body. 1854: Charles Bourseul publishes a description of a make-break telephone transmitter and receiver in L'Illustration, (Paris) but does not construct a working instrument 1854: Antonio Meucci demonstrates an electric voice operated device in New York, but it is not clear what kind of device he demonstrated...

List Of United States Telephone Companies ... Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first US patent for the telephone in 1876...

Telephone ... All modern telephones have a microphone to speak into, an earphone (or 'speaker') which reproduces the voice of the other person, a ringer which makes a sound to alert the owner when a call is coming in, and a keypad (or on older phones a telephone dial) to enter the telephone number of the telephone to be called...

Voice Over IP ... Internet telephony refers to communications services —voice, fax, SMS, and/or voice-messaging applications— that are transported via the Internet, rather than the public switched telephone network (PSTN). The steps involved in originating a VoIP telephone call are signaling and media channel setup, digitization of the analog voice signal, encoding, packetization, and transmission as Internet Protocol (IP) packets over a packet-switched network...

History Of The Telephone ... A different device, the tin can telephone, or 'lover's phone', has also been known for centuries. It connected two diaphragms with a taut string or wire, which transmitted sound by mechanical vibrations from one to the other along the wire, and not by a modulated electrical current...

Reis Telephone ... The distinction between smartphones and feature phones can be vague and there is no official definition for what constitutes the difference between them... One of the most significant differences is that the advanced application programming interfaces (APIs) on smartphones for running third-party applications can allow those applications to have better integration with the phone's OS and hardware than is typical with feature phones... In comparison, feature phones more commonly run on proprietary firmware, with third-party software support through platforms such as Java ME or BREW...

Johann Philipp Reis ... Meucci set up a form of voice communication link in his Staten Island home that connected its second floor bedroom to his laboratory. He submitted a patent caveat for his telephonic device to the U. S...

Membranophone ... The entries in this timeline are mass products, technologies and single objects, mostly falling into the two categories: Indigenous inventions, either having worldwide importance (like arc welding, assault rifle, satellite) or more local significance (like onion dome, khokhloma, ushanka); Products and objects with unique superlative characteristics and records associated with them (like Tsar Cannon, AK-47, Arktika class icebreaker). This timeline includes products and technologies introduced by any citizens and peoples of Russia and her predecessor states, regardless of ethnicity, and including inventions of naturalized immigrant citizens...

History Of Mobile Phones ... Mobile phone history is often divided into generations (first, second, third and so on) to mark significant step changes in capabilities as the technology improved. Pioneers of radio telephony By 1930, telephone customers in the United States could place a call to a passenger on a liner in the Atlantic Ocean...

Elisha Gray ... Gray is also considered to be the father of the modern music synthesizer, and was granted over 70 patents for his inventions. Biography and early inventions Born into a Quaker family in Barnesville, Ohio, Gray was brought up on a farm...

Sony Mobile Communications ... Most membranophones are drums. Hornbostel-Sachs divides drums into three main types: struck drums, where the skin is hit with a stick, the hand, or something else; string drums, where a knotted string attached to the skin is pulled, passing its vibrations onto the skin; and friction drums, where some sort of rubbing motion causes the skin to vibrate (a common type has a stick passing through a hole in the skin which is pulled back and forth)...

Alexander Graham Bell ... Later he managed to get his automaton to play any piece performed by a musician on an organ by muting the organ's keys and connecting them to the automaton's fingers. A complex automaton was described in the same 1865 news article that described Manzetti's telephone...

Innocenzo Manzetti ... At the end of his fourteenth year, Reis was accepted to a Hassel Institute, at Frankfurt am Main, where he learned Latin and Italian. A love of science became apparent, and his guardians were recommended to send him to the Polytechnic School of Karlsruhe...
