What are dynamic headphones?
There are many ways to categorize headphones, whether it is style, strength, brand or sound quality. However, all headphones fall into one of the two basic categories: dynamic or electrostatic. These categories set up headphones on the type of technology used to create their sound. The difference between the two types is in the converter's principle used; This is how the headphones convert an electrical signal from the media player to sound waves that can be heard.
Dynamic headphones work just like two miniature speakers. The signal is transmitted by connection to the standard connector. Once the electrical signal reaches the headphone, the magnet forces a voice coil that quickly vibrates inside the diaphragm-papers, a fibrous or plastic conical object. The inner works are then raised up and down like a piston, often faster than the eye. This quick vibration is what mixes the air and creates vibration called sound waves, which are then picked up by our ear drums.
Dynamic headphones are by far the most common type used by the average listener of music, musicians and professional studio blends. The most popular manufacturers in the music industry all create dynamic headphones, including Sony, Bose and Audio-Technica. They may cost $ 8 or $ 800 USD (USD) and can be involved or wireless, open -air or closed, ear buds or quality of study.
Electrostatic headphones on the other hand require an amplifier to create an electric field. The field forces air through perforation in sandwich metal plates surrounding a thin plastic membrane. As a result of metal plating, electrostatic phones often have a rectangular shape, unlike a common round shape of dynamic headset.
Most experts agree that electrostatic phones can actually produce better sound than dynamic headphones. Reason whyThey are not more popular, it is that they are much more expensive, starting with about $ 1,000 and reaching almost $ 15,000 for the best industry.
both of these headphones - sometimes called "cans" or "ears" by those who are in the disk and the radio industry - are far from the original designs that date back to use with radio and phones from the beginning of the 20th century. However, although materials and electrical signal are newer development, the system of magnet and the coil of dynamic headphones was used at the turn of the 20th century.
