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...

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...

Planar Magnetic Speakers

What are Planar Magnetic Speakers?   The planar magnetic speaker is a type of speaker closely related to the electrostatic speaker. It is nearly identical in radiation concept to an electrostatic loudspeaker, having a large, thin, vertically orientated plastic...

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...
