The pole piece and the back plate are often made of one piece, called a pole plate or yoke. When an electrical signal is applied to the voice coil, a magnetic field is created by the electric current in the voice coil, making it a variable electromagnet. The coil and the magnetic system of the conductor work together in the same way as a solenoid and generate a mechanical force that moves the coil. The application of alternating current moves the cone back and forth, accelerates and reproduces the sound under the control of the applied electrical signal coming from the amplifier.
While this setting is usually better than a single full-range speaker, the tweeter mounted on the woofer prevents the woofer’s sound output. They are designed to be housed in a separate enclosure that is physically placed away from the main speaker that houses high, medium and low frequency range controllers. Electrostatic speakers use a high-voltage electric field to drive a statically charged thin diaphragm. Because they are driven over the entire membrane surface rather than from a small voice coil, they usually offer more linear, less deforming motion than dynamic controllers. They also have a relatively narrow scattering pattern that can accurately position the sound field. However, their optimal listening area is small and they are not very efficient speakers.
Because the thin membrane moves very little, it receives current from an amplifier, which creates sound. 3-way crossovers (divide the input signal into 3 output signals: low-frequency, mid-frequency and high-frequency signals and they are all sent to different controllers). 2- and 3-way crossovers are the most common types, but there are also speakers with 4 or more different drivers in a cabinet that require 4-way (or n-way) crossovers. Column Array speakers are also a popular choice for house or worship sound. Column speakers are composed of multiple small cone-like controllers arranged vertically in a tall but narrow housing, resulting in a narrow vertical dispersion and wide horizontal dispersion.
Wireless speakers are very similar to traditional speakers, but receive audio signals using radio frequency waves rather than audio cables. There is usually an amplifier built into the speaker cabinet because RF waves alone are not enough to propel the speaker. The manufacturers of these speakers design them to be as light as possible while producing the maximum amount of audio output efficiency.
These speakers work by relying on the interaction between the current of an amplifier and a magnetic field. In principle, the coil is placed centrally and evenly in a magnetic field. As the current from an amplifier flows through the coil, the coil begins to move due to the force generated in the magnetic field. The force creates movements in the coil which in turn cause the cone to vibrate accordingly to produce sound. To accurately reproduce very low bass tones without unwanted resonances, subwoofer systems must be solidly constructed and well-reinforced to prevent unwanted sounds of cabinet vibration. Many subwoofer systems include integrated power amplifiers and electronic subsonic filters, with additional controls relevant to low-frequency playback (e.g., a cross button and phase switch).
This type of subwoofer is self-contained and uses a speaker-to-amplifier configuration that optimally adapts to the functions and wraps them together. Essentially, an active subwoofer only needs a single cable connection from your home theater receiver or surround sound preamp output, and it’s powered by its own built-in amplifier. They are extremely easy to use with modern home theater receivers, as most receivers are equipped with one or two subwoofer preamp line outputs designed directly to connect your active subwoofer. Speaker drivers are the transducer elements of the speakers that are ultimately responsible for converting the audio signal into sound. While there are different types of drivers, pretty much all of them use a conductive element to move an aperture and produce sound.
However, it differs from the aforementioned dynamic and flat magnetic designs and is its own type of speaker driver. These speaker drivers are built with different design philosophies and often have different audio and power speaker rentals miami requirements than typical dynamic drivers. When we use the term driver, we usually refer to dynamic speaker drivers. The other types can be called controllers, although we can refrain from naming them to avoid confusion.
The sound quality depends on many factors: the quality of the components installed in the crossover, the configuration of the crossover, the quality and type of housing, etc. When the electrical signal from the amplifier is brought into the coil, the coil moves back and forth and, along with the coil, the diaphragm moves while attached to it. The diaphragm pushes and pulls the air in front of it, creating sound waves.
