Tweeter Speakers

Tweeter speakers are audio drivers contained in a speaker system. They are considered a type of electromechanical loudspeaker which produces both sound and music at high frequencies. Hence, these devices are capable of producing the upper range of a sound. Tweeter speakers are usually small, they produce small wave-length audio, and have a small cone.…

Coaxial Speakers

A coaxial speaker system is a system in which the individual driver unit emits a sound from the same point of axis.  There are two main types of coaxial speakers: the compact coaxial speaker and the two-way high-power coaxial speaker. The compact coaxial speaker is frequently used for in-car audio and it includes two or…

Moving Iron Speaker

A moving iron speaker, also known as a moving-coil loudspeaker, is one of the earliest types of speakers. The moving iron speaker is an essential part of small size speakers because of their size and low-cost. The design of the moving-iron speaker involves a ferrous-metal diaphragm, a permanent magnet and an insulated wire. The coil…

Piezoelectric Speaker

A piezoelectric speaker, also known as piezo, buzzer, and crystal loudspeaker, is a device that uses a piezoelectric effect to produce a sound. The sound is generated by applying a voltage to a piezoelectric material that creates a mechanical motion. Resonators and diaphragms often transform the mechanical motion into an audible sound. It’s worth mentioning…

Magnetostatic Loudspeaker

A magnetostatic loudspeaker is a dipole loudspeaker that has many similarities with the electrostatic loudspeaker. Magnetostatic loudspeakers use high currents and its construction involves permanent magnets which function as a static magnetic field. The construction of magnetostatic loudspeakers also includes wires that carry the audio frequency currents. These wires are attached to a thin diaphragm.…

Magnetostrictive Speakers

In simple terms, magnetostrictive is a general property of ferromagnetic materials that causes them to change their shape or dimensions during the process of magnetization. The variation of the materials’ magnetization is due to the applied magnetic field changes of the magnetostrictive strain. Eventually, it reaches its saturation value, which is λ. The magnetostrictive effect…

Electrostatic Speakers

The electrostatic principle has many advantages which can be applied to the construction of electrostatic speakers. The construction of loudspeakers based on the electrostatic principle helps to create speakers with better transient response, lower coloration, as well as lower non-linear distortion. The radiation qualities tend to work better with room acoustics.  The electrostatic loudspeaker includes…

Ribbon Speakers

The diaphragm of a ribbon speaker is conductive, positioned in a transverse magnetic field and supported by both ends. When an air current passes through the diaphragm, a perpendicular force is created. This generates an even trust on the diaphragm which is typically thin and light.  Ribbon speakers and electrostatic speakers have many things in…

Planar Magnetic Speakers

The planar magnetic speaker is a type of speaker that is similar to the electrostatic speaker. These devices are nearly identical since they both have a large, thin, vertically oriented plastic diaphragm that operates as a vibrating element. Planas magnetic speakers are based on traditional magnetic principles. In essence, the thin wires from a plastic…

Bending Wave Speakers

Bending wave speakers operate based on a basic principle. For a moment, imagine throwing a stone into a lake. When the stone falls, the surface of the water suffers a destabilization caused by an impulse. The wave produced tends to spread evenly on each side. This basic principle can be applied to bending wave loudspeakers…
