Electrodynamic loudspeaker cone shape mostly , dome -shaped ; cone speaker (cone speaker) structure.

Speaker cone structure can be divided into three parts:
1 > vibration system Bluetooth Speaker including the diaphragm , voice coil, dampers , dust cover , etc.
2 > of the magnet system comprises a magnetic plate , magnetic columns, the magnetic plate , a magnet , etc.
3 > auxiliary systems including frames, blank , wiring racks, phase plug strip .
According to Faraday 's law , when a current-carrying conductor through the magnetic field , an electromotive force Multimedia Speaker will be in a direction in line with Fleming 's left hand rule , force and current, the magnetic field direction perpendicular to each other , and the current size of the force , the length of the wire , a magnetic flux density proportional . When the voice coil audio input alternating current, alternating coil is subjected to a driving force alternating movement, led cone vibration, repeatedly pushing the air and sound.
