All speaker drivers have a means of electrically inducing back-and-forth motion. Typically there is a tightly wound coil of insulated wire (known as a voice coil) attached to the neck of the driver's cone. In a ribbon speaker, the voice coil may be printed or bonded onto a sheet of very thin paper, aluminum, fiberglass or plastic.
A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal . [ 1 ] It is commonly applied to sonar , radar , and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum ).
The output pattern of an industrial loudspeaker shown using spherical polar plots taken at six frequencies. Loudspeaker measurement is the practice of determining the behaviour of loudspeakers by measuring various aspects of performance.
The other attempts to arrange the listening room to be 'dead' acoustically, leaving indirect sound to the dispersion of the speakers need only be sufficient to cover the listening positions. A dead or inert acoustic may be best, especially if properly filled with 'surround' reproduction, so that the reverberant field of the original space is ...
The term loudspeaker may refer to individual transducers (also known as drivers) or to complete speaker systems consisting of an enclosure and one or more drivers.. To adequately and accurately reproduce a wide range of frequencies with even coverage, most loudspeaker systems employ more than one driver, particularly for higher sound pressure level (SPL) or maximum accuracy.
A typical sound reinforcement system consists of; input transducers (e.g., microphones), which convert sound energy such as a person singing into an electric signal, signal processors which alter the signal characteristics (e.g., equalizers that adjust the bass and treble, compressors that reduce signal peaks, etc.), amplifiers, which produce a ...
Several generic digital data connection standards are designed to carry audio/video data along with other data and power: USB was designed as a single connector to support all needs, including any generic data, audio/video, power, and more; DisplayLink is its most successful Audio+Video protocol. Until the 3.0 revision, very low data rates ...
Advantages of electrostatic loudspeakers include: the very low mass of the diaphragm, which is driven across its whole surface; exemplary frequency response (both in amplitude and phase) [citation needed] because the principle of generating force and pressure is almost free from resonances unlike the more common electrodynamic driver.
