Class B Amplifier

Class B Amplifier advantages   The Class B Amplifier has a significant advantage over their Class A amplifier cousins in that no current flows through the transistors when they are in their quiescent state (i.e., with no input signal). Therefore, the output...

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...

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...
