What is a piezoelectric tweeter?
Piezoelectric tweeter is a type of audio speaker created to generate high -frequency sounds. This variety of speaker uses a special piezoelectric crystal that is connected to a movable diaphragm. Piezo Tweeters, as they are sometimes called, are usually used to create sounds between 2,000 Hertz (Hz) and 20,000 Hz frequencies. This sound is close to the upper range limit that can be detected by a human ear.
The word "tweeter" is an informal expression that has yet become a standard term among sound enthusiasts. This name comes from the high -frequency "tweet" noise that birds release. On the other hand, the "Woofer" has a low -frequency cortex or "woof" dog. Both both Tweets and Baso are often used to increase sound quality on extreme high and low audio strains.
In the piezoelectric tweeter there are physical vibrations that generate sound waves, created by means of piezoelectric material such as quartz. These types of crystals are onThere is a collection and a change in size when they are connected to an electric charge. This phenomenon was known in the 18th century; However, scientists did not create practical piezoelectric devices until the age of 20.
Although they were not known under this name, piezoelectric tweeteers were not used for music for the first time, but rather for Sonar. The high -frequency abilities of the piezoelectric speakers were used during the First World War to discourage sound waves underwater. Each echo was timed to determine the distance to the underwater object. Modern Piezo Tweeters use the same foundations of these early sonar converters.
When the sound signal passes through a piezoelectric crystal, the structure oscillates synchronization with an audio source. A membrane made of paper or other flexible material is connected to the piezoelectric tweeter crystal. This structure intensifies the crystal vibratioNS and creates vibrations in the surrounding air. These resulting sound waves are interpreted as high -frequency sounds. The faster the crystal and the membrane oscillate, the higher the sound pitch.
The piezoelectric tweeter is not in any sound settings. Some basic sound systems simply rely on a medium -sized speaker and create vibrations on the general frequency range. However, in sound installations with high loyalty, where the accurate sound and reproduction of music is important, tweeters help to improve the sound of generating the highest sound sound.
