Microphones are used not only by professional musicians, but also by ordinary users for entertainment and communication. When choosing, the buyer is faced with a large assortment offered by manufacturers. One of the most popular and high-quality devices is a dynamic microphone. This article provides up-to-date information with a complete description of the accessory.
A dynamic microphone is used to convert acoustic oscillations into an electrical signal. It consists of a thin membrane, which is called the "diaphragm". A thin wire forms a coil, and a magnet creates a magnetic field. Acoustic fluctuations cause changes in air pressure, which contributes to the movement of the diaphragm. Due to this, the coil begins its movement in a magnetic field. These movements contribute to the rotation of the wire, thereby creating an electric current.
The main feature of a dynamic microphone is the ability to work without additional power. This distinguishes it from capacitor type devices. Such electroacoustic devices are suitable for so-called live concert performances or live broadcasts. Journalists prefer to use the dynamic type of the device, as they often have to report in emergency mode.
REFERENCE!The dynamic version of the microphone has a large size (when compared with other options).
Like any device, the dynamic type of microphone has advantages and disadvantages. When choosing a model, you must carefully familiarize yourself with the positive and negative features.
Benefits:
- relatively affordable cost;
- no need for additional nutrition;
- high rates of absorption and elimination of extraneous sounds;
- excellent ability to reboot;
- resistance to high humidity or temperature;
- resistance to mechanical damage.
In addition, this type of electro-acoustic device is suitable for recording very loud or low sounds. It is also an indispensable device when working with guitar amps or percussion instruments.
REFERENCE!A plus of a dynamic mechanism can also be called durability of work. The device is able to function for a long period without any deviations or sudden breakdowns.
Disadvantages:
- quite large size (this is due to the peculiarities of the mechanism);
- lower rates of purity and naturalness (compared with the condenser type);
- low frequency range;
- reduced tone transfer.
The microphone is necessary when conducting "live" vocal performances, various press conferences and reports - the scope is quite wide. By the choice of such an important device must be approached with special care, given its features.
