Who invented the first computer speaker
Alongside a scientific career, Ada Lovelace right had three children. The mathematician Anna Siffert left believes that balancing a family with a research career is still a challenge for many women scientists today. Shortly after her birth, her parents' marriage is already over. Out of fear that Ada might inherit the stormy and unpredictable temper of her poet father, the mathematically talented Annabella, once called 'the princess of parallelograms' by Byron, makes sure that her daughter receives a scientific education.

What is a Speaker?
A loudspeaker is an electroacoustic transducer; a device which converts an electrical audio signal into a corresponding sound. The first crude loudspeakers were invented during the development of telephone systems in the late s, but electronic amplification by vacuum tube beginning around made loudspeakers truly practical. By the s they were used in radios, phonographs, public address systems and theatre sound systems for talking motion pictures.
The most popular speaker used today is the dynamic speaker, invented in by Edward W. Kellogg and Chester W. The dynamic speaker operates on the same basic principle as a dynamic microphone, but in reverse, to produce sound from an electrical signal. When an alternating current electrical audio signal input is applied through the voice coil, a coil of wire suspended in a circular gap between the poles of a permanent magnet, the coil is forced to move rapidly back and forth due to Faraday's law of induction, which causes a diaphragm usually conically shaped attached to the coil to move back and forth, pushing on the air to create sound waves.
Besides this most common method, there are several alternative technologies that can be used to convert an electrical signal into sound. Where high fidelity reproduction of sound is required, multiple loudspeakers may be used, each reproducing a part of the audible frequency range.
Miniature loudspeakers are found in devices such as radio and TV receivers, and many forms of music players. Larger loudspeaker systems are used for music, sound reinforcement in theatres and concerts, and in public address systems. Speakers are typically housed in an enclosure which is often a rectangular or square box made of wood or sometimes plastic.
Johann Philipp Reis installed an electric loudspeaker in his telephone in ; it was capable of reproducing clear tones, but also could reproduce muffled speech after a few revisions. Alexander Graham Bell patented his first electric loudspeaker capable of reproducing intelligible speech as part of his telephone in , which was followed in by an improved version from Ernst Siemens. Nikola Tesla reportedly made a similar device in , but he was not issued a patent.
During this time, Thomas Edison was issued a British patent for a system using compressed air as an amplifying mechanism for his early cylinder phonographs, but he ultimately settled for the familiar metal horn driven by a membrane attached to the stylus. In , Horace Short patented a design for a loudspeaker driven by compressed air; he then sold the rights to Charles Parsons, who was issued several additional British patents before However, these designs were significantly limited by their poor sound quality and their inability to reproduce sound at low volume.
Variants of the system were used for public address applications, and more recently, other variations have been used to test space-equipment resistance to the very loud sound and vibration levels that the launching of rockets produces. The modern design of moving-coil also called dynamic drivers was established by Oliver Lodge in The first practical application of moving-coil loudspeakers was established by Danish engineer Peter L. Jensen and Edwin Pridham, in Napa, California. Jensen was denied patents.
Being unsuccessful in selling their product to telephone companies, in they changed strategy to public address, and named their product Magnavox.
Jensen was, for years after the invention of the loudspeaker, a part owner of The Magnavox Company. The moving-coil principle commonly used today in direct radiators was patented in by Chester W. Rice and Edward W. The key difference between previous attempts and the patent by Rice and Kellogg is the adjustment of mechanical parameters so that the fundamental resonance of the moving system is below the frequency where the cone's radiation impedance becomes uniform.
About this same period, Walter H. Schottky invented the first ribbon loudspeaker together with Dr. Erwin Gerlach. These first loudspeakers used electromagnets, because large, powerful permanent magnets were generally not available at a reasonable price. The coil of an electromagnet, called a field coil, was energized by current through a second pair of connections to the driver. This winding usually served a dual role, acting also as a choke coil, filtering the power supply of the amplifier that the loudspeaker was connected to.
AC ripple in the current was attenuated by the action of passing through the choke coil. However, AC line frequencies tended to modulate the audio signal going to the voice coil and added to the audible hum. In the s, loudspeaker manufacturers began to combine two and three bandpasses' worth of drivers in order to increase frequency response and sound pressure level.
In , the first film industry-standard loudspeaker system, "The Shearer Horn System for Theatres" a two-way system , was introduced by Metro-Goldwyn-Mayer. It used four 15? At the New York World's Fair, a very large two-way public address system was mounted on a tower at Flushing Meadows.
The eight 27? High-frequency drivers were likely made by Western Electric. Altec Lansing introduced the , which became their most famous coaxial Duplex driver, in It incorporated a high-frequency horn that sent sound through the middle of a inch woofer for near-point-source performance. Altec's "Voice of the Theatre" loudspeaker system arrived in the marketplace in , offering better coherence and clarity at the high output levels necessary in movie theaters.
The Academy of Motion Picture Arts and Sciences immediately began testing its sonic characteristics; they made it the film house industry standard in In , Edgar Villchur developed the acoustic suspension principle of loudspeaker design in Cambridge, Massachusetts.
This allowed for better bass response from loudspeakers mounted in smaller cabinets. He and his partner Henry Kloss formed the Acoustic Research company to manufacture and market speaker systems using this principle. Subsequently, continuous developments in enclosure design and materials led to significant audible improvements.
The most notable improvements in modern speakers are improvements in cone materials, the introduction of higher-temperature adhesives, improved permanent magnet materials, improved measurement techniques, computer-aided design, and finite element analysis.

Invention of First Laptop Computer
That same year in Germany, engineer Konrad Zuse built his Z2 computer, also using telephone company relays. Their first product, the HP A Audio Oscillator, rapidly became a popular piece of test equipment for engineers. In , Bell Telephone Laboratories completes this calculator, designed by scientist George Stibitz. Stibitz stunned the group by performing calculations remotely on the CNC located in New York City using a Teletype terminal connected via to New York over special telephone lines. This is likely the first example of remote access computing. The Z3, an early computer built by German engineer Konrad Zuse working in complete isolation from developments elsewhere, uses 2, relays, performs floating point binary arithmetic, and has a bit word length. The Z3 was used for aerodynamic calculations but was destroyed in a bombing raid on Berlin in late
The Best Computer Speakers
A speaker is a term used to describe the user who is giving vocal commands to a software program. A computer speaker is an output hardware device that connects to a computer to generate sound. The signal used to produce the sound that comes from a computer speaker is created by the computer's sound card. Speakers are made up of a cone, an iron coil, a magnet, and housing case. When the speaker receives electrical input from a device, it sends the current through the causing it to move back and forth. This motion then vibrates the outer cone, generating sound waves picked up by our ears. When computers were initially released, they had onboard speakers built into the chassis that generated a series of different tones and beeps. The first internal computer speaker was invented by IBM in and produced basic, low quality sound. As technology progressed, onboard speakers moved into the computer monitor and acquired the ability to produce voices, music, and other sound effects.
Computer speakers
Sonos basically invented the multi-room category of home audio, starting as a software company in the early s before integrating its Wi-Fi-enabled network into hardware a few years later. Its first amplifier which became the Connect:Amp and subsequent speakers were great, but the real beauty of Sonos is its ecosystem of audio products that make listening to music at home really easy. The magic of Sonos is the ability to group any number of Sonos speakers together, provided they are all connected to the same Wi-Fi network, and have them all playing in sync through out the house. Alternatively, they can all be playing different tunes if you'd like. And it's all controlled through a smartphone app.

The very first form of loudspeaker came to be when telephone systems were developed in the late s. But it was in that loudspeakers really became practical -- due in part to electronic amplification by a vacuum tube. By the s, they were used in radios, phonographs , public address systems and theater sound systems for talking motion pictures. By definition, a loudspeaker is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. The most common type of loudspeaker today is the dynamic speaker.
