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...

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...

Transparent Ionic Conduction Speaker

What is a Transparent Ionic Conduction Speaker?   A transparent ionic conduction speaker is a relatively new form of technology. In 2013, a research team from Harvard University introduced transparent ionic conduction speakers to the public. Jeong-Yun Sun and...

Heil Air-Motion Speakers

What are Heil Air-Motion Speakers?   People often confuse Air-Motion Speakers’with ribbon loudspeakers when they see the folded diaphragms set in the shorthorn. But they are quite different. A ribbon radiates the sound by the whole diaphragm moving backward...

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...
