The cone cone speaker is generally composed of three parts:

1. Magnetic circuit system (magnet, T-iron, washer).

2. Vibration system (vibration plate <paper cone, sound film>, voice coil).

3. Supporting auxiliary system (centering support <elastic wave>, basin frame, cushion edge, terminal board).

Specific introduction to the above three major systems:

1. Voice coil: The voice coil is the driving unit of the cone paper cone speaker. It is made of very thin copper wire (copper wire / aluminum wire) in two layers (four layers) around the bone and added (paper tube / aluminum sheet / Film, etc.), generally around dozens of turns, placed in the magnetic gap formed by the magnetic core and the magnetic plate. The voice coil and the paper cone are fixed together. When the dynamic and static current signals pass through the voice coil, the vibration of the voice coil drives the paper cone to vibrate.

2. Paper cone (drum paper): There are many varieties of materials used in the cone diaphragm of the cone cone speaker. There are generally two types of natural fibers and artificial fibers. Natural fibers often use cotton, wood, wool, silk, etc., and artificial fibers just use rayon, nylon, glass fiber, etc. Because the paper cone is the dynamic and static radiation equipment of the speaker, it determines the sound emission function of the speaker to a large extent. .

3. Folding ring (edge flange): The folding ring is set to ensure that the paper cone moves along the axial direction of the speaker and restricts the lateral movement, and together plays a role in preventing the paper cone from daring to circulate in front and back. In addition to the commonly used paper cone materials, the material of the folding ring also uses plastic, natural rubber, etc., and is bonded to the paper cone after hot pressing.

4.The rigidity or gentleness of the hanging edge and the elastic wave will affect the movement speed of the cone.For the full and gentleness of the speaker, the elastic wave supply is about 80%, the hanging edge supply is about 20%, and the hanging edge There are two functions, its original job is to stick the voice coil to the center of the gap of the pole piece, however

5. Regarding the vibration mode of the cone's margin, the damping effect formed by the overhang is very important. The thickness of the overhang and the choice of materials change the response of the horn dramatically, damping the cone distortion and preventing the cone The ability of the sound waves reflected from the back can change the combination of the amplitude and phase of the misinterpretation mode, making it an indispensable element of the cone and something that can respond.

6. Centering piece (elastic wave): The centering piece is used to support the joint of the voice coil and the paper cone to ensure that it is vertical and not inclined. There are many concentric rings on the centering support piece, so that the voice coil can move up and down freely in the magnetic gap without lateral movement, to ensure that the voice coil does not collide with the magnetic conductive plate. The dust cover on the centering support is to prevent external dust from falling into the magnetic gap, to prevent the formation of dust and friction with the voice coil, and to cause abnormal movement of the speaker.

(Centering piece) The elastic wave has some functions. Its second function is to insist that the voice coil is centered in the gap. At the same time, it also submitted an application to prevent foreign gray particles from intruding into the gap. The primary restoring force of the monomer, however, the rigidity of the elastic wave also affects the resonance of the speaker (FO). The resonance of the speaker is a function of euphemism and quality.
