RCA Photophone
RCA Photophone was the trade name given to one of four major competing technologies that emerged in the American film industry in the late 1920s for synchronizing electrically recorded audio to a motion picture image. RCA Photophone was an optical sound, "variable-area" film exposure system, in which the modulated area (width) corresponded to the waveform of the audio signal. The four other major technologies were the Warner Bros. Vitaphone sound-on-disc system, as well as three "variable-density" sound-on-film systems, Lee De Forest's Phonofilm, and Fox- Case's Movietone, and the German system Tri-Ergon. When Joseph P. Kennedy and other investors merged Film Booking Offices of America (FBO) with the Keith-Albee-Orpheum theater chain and Radio Corporation of America; the resulting movie studio RKO Radio Pictures used RCA Photophone as its primary sound system. In March 1929, RKO released ''Syncopation'', the first live-recorded film made with RCA Photophone. His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woofer
A woofer or bass speaker is a technical term for a loudspeaker driver designed to produce low frequency sounds, typically from 50 up to 200 Hz. The name is from the onomatopoeic English word for a dog's deep bark, " woof" (in contrast to a '' tweeter'', the name used for loudspeakers designed to reproduce high-frequency sounds, deriving from the shrill calls of birds, " tweets"). The most common design for a woofer is the electrodynamic driver, which typically uses a stiff paper cone, driven by a voice coil surrounded by a magnetic field. The voice coil is attached by adhesives to the back of the loudspeaker cone. The voice coil and the magnet form a linear electric motor. When current flows through the voice coil, the coil moves in relation to the frame according to Fleming's left hand rule for motors, causing the coil to push or pull on the driver cone in a piston-like way. The resulting motion of the cone creates sound waves, as it moves in and out. At ordinary sound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression Driver
A compression driver is a small specialized diaphragm loudspeaker which generates the sound in a horn loudspeaker. It is attached to an horn (acoustic), acoustic horn, a widening duct which serves to radiate the sound efficiently into the air. It works in a "compression" mode; the area of the loudspeaker diaphragm is significantly larger than the throat aperture of the horn so that it provides high sound pressures. Horn-loaded compression drivers can achieve very high efficiencies, around 10 times the efficiency of direct-radiating cone loudspeakers. They are used as midrange driver, midrange and tweeter drivers in high power Sound reinforcement system, sound reinforcement loudspeakers, and in reflex or folded-horn loudspeakers in megaphones and public address systems. History In 1924 C. R. Hanna and J. Slepian were the first to discuss the benefits of using a large radiating diaphragm with a horn of smaller throat area as a means of increasing the efficiency of horn lo ...

John Kenneth Hilliard
John Kenneth Hilliard (October 1901 – March 21, 1989) was an American acoustical and electrical engineer who pioneered a number of important loudspeaker concepts and designs. He helped develop the practical use of recording sound for film and won an Academy Award in 1935. He designed movie theater sound systems, and he worked on radar as well as submarine detection equipment during World War II. Hilliard collaborated with James B. "Jim" Lansing in creating the long-lived Altec Voice of the Theatre speaker system. Hilliard researched high-intensity acoustics, vibration, miniaturization and long-line communications for NASA and the Air Force. Near the end of his career, he standardized noise-control criteria for home construction in California, a pattern since applied to new homes throughout the U.S. Education Born in October 1901 in Wyndmere, North Dakota, Hilliard received his B.S. degree from Hamline University in St. Paul, Minnesota at 24 years of age.
