The variation in loudspeaker impedance is a consideration in audio amplifier design. Among other things, amplifiers designed to cope with such variations are more reliable. There are two main factors to consider when matching a speaker to an amplifier.
Dave Wilson of Wilson audio, used JansZen tweeters in his famous, WAMM, Wilson Audio Modulator Monitor. That speaker sold for $220,000 a pair when it was discontinued. The developers of the Tri-Ergon sound-on-film sound film system had developed a primitive design of electrostatic loudspeaker as early as 1919. David JansZen, son of Arthur ...
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 loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
Another specialised pole piece is the armature of an electromechanical solenoid, which produces work by being attracted by an electromagnet when the magnet is actuated. An electron lens contains two specialised pole pieces used to guide the electromagnetic field lines of the wire coils of the permanent magnet, these field lines guides the ...
The image above shows two ways in which the voice coil is immersed in the magnetic field. The most common method is the overhung design where the height of the voice coil is greater than the magnetic gap's height. The underhung design which is used mostly in high-end speakers has the coil's height smaller than the gap's. The differences ...
Loudspeaker acoustics is a subfield of acoustical engineering concerned with the design of loudspeakers. [1] It focuses on the reproduction of sound and the parameters involved in doing so in actual equipment.
A passive radiator speaker uses a second passive driver, or drone, to produce similar low-frequency extension, or efficiency increase, or enclosure size reduction, similar to ported enclosures. Small [28] [29] and Hurlburt [30] have published the results of research into the analysis and design of passive-radiator loudspeaker systems. The ...
