Loud Speaker

• What is a speaker?Mylar Speakers?

  Loudspeaker is a kind of energy conversion device that converts electrical signal into acoustic signal. The performance of loudspeaker has a great impact on sound quality.Miniature speaker is the weakest device in audio equipment, and it is the most important component for audio effect. There are many kinds of Intercom Speaker, and the prices vary greatly. Audio electric energy makes its paper basin or diaphragm vibrate and resonate with the surrounding air through electromagnetic, piezoelectric or electrostatic effects.

  FBelec general Multimedia speakers is composed of magnet, frame, centering support, die folding ring and conical paper basin.

  Basic features:

  (1) alnico-type Mylar speaker has two terminals (two leads). When a single speaker is used, the two pins do not have positive and negative polarity. When multiple speakers are used at the same time, the two pins have polarity.

  (2) SMD Type Speaker has a paper basin. Its color is usually black or white.

  (3) The shapes of speakers include round, square and oval.

  (4) There is a magnet on the back of the speaker paper basin. When the external magnetic speaker contacts the magnet with a metal screwdriver, it will feel the existence of magnetism; there is no such feeling in the internal magnetic speaker, but there is a magnet inside the shell.

  (5) The loudspeaker is installed on the machine panel or in the speaker box.

  FBelec's loudspeakers are of good quality and low price. They are sold to the United States, Germany and South Africa
