Class D Amplifier

What is a Class D Amplifier?   A class D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches. They do not operate as linear gain devices as in other amplifiers....

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...

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...
