Plasma speaker. Plasma speakers or ionophones are a form of loudspeaker which varies air pressure via an electrical plasma instead of a solid diaphragm. The plasma arc heats the surrounding air causing it to expand. Varying the electrical signal that drives the plasma and connected to the output of an audio amplifier, the plasma size varies ...
Bi-amping - An active crossover with two amplifiers. Bi-amping and tri-amping is the practice of using two or three audio amplifiers respectively to amplify different audio frequency ranges, with the amplified signals being routed to different speaker drivers, such as woofers, subwoofers and tweeters. With bi-amping and tri-amping, an audio ...
Acoustic suspension. An acoustic suspension loudspeaker is a type of speaker enclosure in which a loudspeaker driver is mounted in a cabinet with a closed back and no ports or vents. Acoustic suspension is a loudspeaker cabinet design that uses one or more loudspeaker drivers mounted in a sealed box. Acoustic suspension systems reduce bass ...
Directional Sound refers to the notion of using various devices to create fields of sound which spread less than most (small) traditional loudspeakers. Several techniques are available to accomplish this, and each has its benefits and drawbacks. Ultimately, choosing a directional sound device depends greatly on the environment in which it is ...
Use This Trick to Make Your Phone Speaker Louder. Easier than making cereal for breakfast. Step 1 - Take a bowl. Step 2 - Throw your phone into it. The shape of the bowl will work as an amplifier ...
A full-range loudspeaker drive unit is defined as a driver which reproduces as much of the audible frequency range as possible, within the limitations imposed by the physical constraints of a specific design. The frequency range of these drivers is maximized through the use of a whizzer cone and other means. Most single driver systems, such as ...
Granted, it might not have the same oomph as a full-fledged 'bar, but it'll certainly sound better than your TV's built-in speakers. (For the record, Apple's HomePod can do this as well, but only ...
In an electrodynamic loudspeaker, a diaphragm is the thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap, vibrating the diaphragm, and producing sound. It can also be called a cone, though not all speaker diaphragms are cone-shaped. Diaphragms are also found in headphones . Quality midrange and bass drivers are ...
