Unidirectional Dynamic Microphone

Unidirectional Microphone

A unidirectional dynamic microphone is one of the cheapest microphones in the market and is very popular. They are creatively designed and are very durable. One of their biggest advantages is that this type of unidirectional microphone is very resistant to moisture and can therefore be used in moist conditions. Since a unidirectional microphone only picks up sound from one direction (its front), the unidirectional dynamic microphone is very effective in undertaking recordings in a studio or a laboratory. It can also be used on a stage where there is the potential of background sound resonating back.

A unidirectional dynamic microphone features an induction coil that is positioned in a magnetic field. The magnetic field is attached to the mic’s diaphragm that receives sound wave. The sound wave that the diaphragm receives makes it vibrate and while it vibrates, the induction coil within the magnetic field moves. The movement of the induction coil results in varying current within the coil. This current or voltage comes out as sound through a speaker.

One of the most common and the most preferred type of unidirectional dynamic microphone is the cardioid dynamic microphone. This microphone is highly effective in capturing both musical and vocal sounds. This is whether the mic is used for recording or on stage. This type of unidirectional dynamic microphone provides for very clean and clear sound output as it avoids any sound from either its sides or the rear. This microphone is the most popular worldwide and is used not only by professionals but also with dignitaries in delivering speeches.

The following reasons can be attributed to the popularity of the unidirectional dynamic microphone:

  1. Durability – The unidirectional dynamic microphone is very durable compared to other types of microphones. The microphone is able to operate for years without breaking down and may only need regular servicing. This is so long as the microphone is handled well and stored appropriately when not in use.
  2. Uniformity – The dynamic microphone has a uniform cardioid sound pick up pattern that ensures smooth performance.
  3. Wide frequency – The unidirectional dynamic microphone has a wide sound frequency of between 40 to 15,000 Hz, wide enough to capture varied sounds.
  4. Cost – A dynamic microphone is reasonably priced in the market and is therefore very affordable.
  5. Quality – A unidirectional dynamic microphone produces very high quality and clear sound, whether in recording or when used on stage.
  6. Availability – A unidirectional microphone is widely and readily available from local musical instrument stores. Online stores offer them as well.

Any type of microphone, the unidirectional dynamic microphone included, has vital accessories. A dynamic microphone requires a microphone stand for support and positioning the microphone. A microphone holder is also important, as it is the piece that is screwed onto a microphone stand and which holds the microphone. Despite the fact that a unidirectional dynamic microphone will only pick up sound only from its front part, it still becomes necessary to have microphone covers that enhance the microphone’s performance and offer protection.

There are varied unidirectional microphone manufacturers producing high quality unidirectional dynamic microphones for use by consumers, especially in the entertainment industry. These manufacturers also manufacture high quality microphone accessories that go along with their microphones. Trusted online musical instrumental stores have become the main outlets for musical instruments.
