Tactile Transducer
A tactile transducer or "bass shaker" is a device which is made on the principle that low bass frequencies can be felt as well as heard. They can be compared with a common loudspeaker, just that the diaphragm is missing. Instead, another object is used as a diaphragm. A shaker transmits low-frequency vibrations into various surfaces so that they can be felt by people. This is called tactile sound. Tactile transducers may augment or in some cases substitute for a subwoofer. One benefit of tactile transducers is they produce little or no noise, if properly installed, as compared with a subwoofer speaker enclosure. Applications A bass-shaker is meant to be firmly attached to some surface such as a seat, couch or floor. The shaker houses a small weight which is driven by a voice coil similar to those found in dynamic loudspeakers. The voice-coil is driven by a low-frequency audio signal from an amplifier; common shakers typically handle 25 to 50 watts of amplifier power. The voice coi ...

Bassline
Bassline (also known as a bass line or bass part) is the term used in many styles of music, such as blues, jazz, funk, Dub music, dub and electronic music, electronic, traditional music, traditional, or classical music for the low-pitched Part (music), instrumental part or line played (in jazz and some forms of popular music) by a rhythm section instrument such as the bass guitar, electric bass, double bass, cello, tuba or keyboard (piano, Hammond organ, electric organ, or synthesizer). In unaccompanied solo performance, basslines may simply be played in the lower register (music), register of any instrument while melody and/or further accompaniment is provided in the middle or upper register. In solo music for piano and pipe organ, these instruments have an excellent lower register that can be used to play a deep bassline. On organs, the bass line is typically played using the pedal keyboard and massive 16' and 32' bass pipes. Riffs and grooves Basslines in Pop music, popular m ...

Low-frequency Effects
The low-frequency effects (LFE) channel is a band-limited audio track that is used for reproducing deep and intense low-frequency sounds in the 3–120 Hz frequency range. This track is normally sent to a subwoofer—a loudspeaker designed to reproduce very low frequencies. LFE channels originated in Dolby Stereo 70 mm film, but in the 1990s and 2000s they became common in home theater systems in order to reproduce film soundtracks found on DVDs and Blu-ray discs. Types Low-pitched musical arts LFEs include both low-pitched musical notes and low-pitched sound effects. The musical soundtrack for many films includes bass instruments that produce very low notes. Until the 1970s, most of the low-pitched instruments were natural, acoustic instruments, such as the double bass or the pipe organ's pedal keyboard. After the 1980s, film scores increasingly used synthesized instruments, including synth bass keyboards, which incorporated very low-pitched notes. Sound ...

Special Effects
Special effects (often abbreviated as SFX, F/X or simply FX) are illusions or visual tricks used in the theatre, film, television, video game, amusement park and simulator industries to simulate the imagined events in a story or virtual world. Special effects are traditionally divided into the categories of mechanical effects and optical effects. With the emergence of digital film-making a distinction between special effects and visual effects has grown, with the latter referring to digital post-production and optical effects, while "special effects" refers to mechanical effects. Mechanical effects (also called practical or physical effects) are usually accomplished during the live-action shooting. This includes the use of mechanized props, scenery, scale models, animatronics, pyrotechnics and atmospheric effects: creating physical wind, rain, fog, snow, clouds, making a car appear to drive by itself and blowing up a building, etc. Mechanical effects are also often inco ...

Video Game Accessories
A video game accessory is a distinct piece of hardware that is required to use a video game console, or one that enriches the video game's play experience. Essentially, video game accessories are everything except the console itself, such as controllers, memory, power adapters (AC), and audio/visual cables. Most video game consoles come with the accessories required to play games out of the box (minus software): one A/V cable, one AC cable, and a controller. Memory is usually the most required accessory outside of these, as game data cannot be saved to compact discs. The companies that manufacture video game consoles also make these accessories for replacement purposes (AC cords and A/V cables) as well as improving the overall experience (extra controllers for more players, or unique devices like light guns and dance pads). There is an entire industry of companies that create accessories for consoles as well, called third-party companies. The prices are often lower than those made ...

Transducers
A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.). The process of converting one form of energy to another is known as transduction. Types * Mechanical transducers, so-called as they convert physical quantities into mechanical outputs or vice versa; * Electrical transducers however convert physical quantities into electrical outputs or signals. Examples of these are: ** a thermocouple that changes temperature differences into a small voltage; ** a linear variable differential transformer (LVDT), used to measure displacement (position) changes by means of electrical signals. Sensors, actuators and transceivers Transducers can be categorized by whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Tudor
David Eugene Tudor (January 20, 1926 – August 13, 1996) was an American pianist and composer of experimental music. Life and career Tudor was born in Philadelphia, Pennsylvania. He studied piano with Irma Wolpe and composition with Stefan Wolpe and became known as one of the leading performers of avant garde piano music. He gave the first American performance of the '' Piano Sonata No. 2'' by Pierre Boulez in 1950, and a European tour in 1954 greatly enhanced his reputation. Karlheinz Stockhausen dedicated his ''Klavierstück VI'' (1955) to Tudor. Tudor also gave early performances of works by Morton Feldman, Earle Brown, Christian Wolff and La Monte Young. The composer with whom Tudor is particularly associated is John Cage; he gave the premiere of Cage's ''Music of Changes'', ''Concert For Piano and Orchestra'' and the notorious ''4' 33"''. Cage said that many of his pieces were written either specifically for Tudor to perform or with him in mind, once stating "what you ...

Loudspeaker
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such ...

Subwoofer
A subwoofer (or sub) is a loudspeaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass, lower in frequency than those which can be (optimally) generated by a woofer. The typical frequency range for a subwoofer is about 20–200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems. Subwoofers are never used alone, as they are intended to ''augment'' the low-frequency range of loudspeakers that cover the higher frequency bands. While the term "subwoofer" technically only refers to the speaker driver, in common parlance, the term often refers to a subwoofer driver mounted in a speaker enclosure (cabinet), often with a built-in amplifier. Subwoofers are made up of one or more woofers mounted in a loudspeaker enclosure—often made of wood—capable of withstanding air pressure while resisting deformation. Subwoofer enclosures come in a variety of designs, including bass reflex (wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Actuator
A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer Peripheral, peripherals such as disk drives and printers, in Valve, valves and Damper (flow), dampers, and in many other places where linear motion is required. Hydraulics, Hydraulic or Pneumatics, pneumatic cylinders inherently produce linear motion. Many other mechanisms are used to generate linear motion from a rotating motor. Types Mechanical actuators Machine, Mechanical linear actuators typically operate by conversion of rotary motion into linear motion. Conversion is commonly made via a few simple types of mechanism: * Screw (simple machine), Screw: leadscrew, screw jack, ball screw and roller screw actuators all operate on the principle of the simple machine known as the screw. By rotating the actuator's nut, the screw shaft moves in a line. * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
