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...

LFO (Low-Frequency Oscillation)

  What is LFO?   LFO or Low-frequency oscillation is an electronic frequency which is usually below 20 Hz or at the bottom of the audio range. So, the human ear cannot hear it. It creates a rhythmic pulse or sweep and is often used to modulate synthesizers,...

Bending Wave Speakers

The principle of Bending Wave Speakers   One of the ways to illustrate the basic principle of how bending wave speakers operate, the following image could be helpful. By throwing a stone into the lake, the water surface is being destabilized by its impulse. This...

Monitor Isolation Pads

What are monitor isolation pads?   Music producers and sound engineers use various devices to decouple the monitors from the surface. Accordingly, most widespread are monitor isolation pads made of dense acoustic foam and metal spikes on which the speakers rest....

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...
