Nanotube Speakers

  What are Cabron Nanotubes?   Carbon nanotubes (CNTs) are tubes that consist of carbon with diameters typically measured in nanometers. Additionally, carbon nanotubes often refer to single-wall carbon nanotubes (SWCNTs) with diameters in the range of a...

Flat Panel Loudspeakers

Flat panel speakers 101   Engineers investigated flat panel speakers in terms of structural vibration and acoustic radiation. A panel speaker primarily consists of a panel and an inertia exciter. Contrary to conventional speakers, they have flexural resonance and...

Thermoacoustic Speakers

What are Thermoacoustic speakers?   Thermoacoustic speakers are speakers that generate sound waves from temperature fluctuations. They rapidly heat and cool conducting materials. Unlike conventional voice-coil speakers, thermoacoustic speakers do not rely on...

Plasma Arc Speakers

What are the Plasma speakers?   Plasma speakers or ionophones are a form of a loudspeaker which varies air pressure via a high-energy electrical plasma instead of a solid diaphragm. Connected to the output of an audio amplifier, plasma speakers vary the size of a...

Ribbon Speakers

Ribbon speakers diaphragm   The diaphragm of a ribbon loudspeaker is conductive and it is positioned in a transverse magnetic field. It is also supported at each end. Current flowing along the diaphragm creates a force perpendicular to it. The mechanism produces...

Magnetostrictive Speakers

Magnetostriction   Magnetostriction (cf. electrostriction) is a property of ferromagnetic materials that causes them to change their shape or dimensions during the process of magnetization. The variation of materials’ magnetization due to the applied...
