Speakers structure

Our most common electric cone speaker cone . Electric cone speaker that in the past , we often say that the speaker cone , although it is still the cone diaphragm -based, but there have been many polymer diaphragm material , metal diaphragm, with cone speakers Car Speaker call it a truly a . Tapered cone speakers generally by the magnetic loop system ( permanent magnet , core columns , magnetic board ) , vibration system ( cone, voice coil ) and supporting auxiliary systems ( dampers , frames, mats side ) and other three parts.
1 . Coil : coil tapered cone speaker drive unit , which is a very thin layers of copper wire wound on a paper tube , there is generally about several circles, known as coils, placed on the guide column and the core magnetic plate magnetic suspect gap . Voice coil and cone fixed together , when the current signal is passed through the voice coil , the coil vibration led the cone vibration.
2 . Cone : cone cone cone Bluetooth Speaker speaker diaphragm materials are used in many types of natural and synthetic fibers are generally two categories . Often used natural fiber , cotton, wood , wool , silk , etc., just using rayon rayon, nylon, glass fiber or the like . As the voice of the speaker cone is a radiation device , to a large extent determines the burst performance of the speaker, so no matter what kind of cone, but also the rigid requirements of both light and good , not because of the ambient temperature and humidity changes and deformation .
3 . Fold ring: Ring is guaranteed fold axial movement along the cone speaker , set the limit lateral movement , but acts as a barrier around the cone empty 'm circulation effect. In addition to the materials used off cone ring material also use plastic , natural rubber, and pressing the adhesive through the cone .
4 . Damper : dampers used to support voice coil and cone binding site , to ensure its vertical rather skewed. There are many concentric ring damper , the voice coil in a magnetic gap that is free to move up and down without moving laterally , to ensure not collide with the magnetic coil plate . Dust damper on the outside in order to prevent dust off the magnetic gap , the voice coil to avoid dust and friction , leaving the speaker to produce unusual sounds .
