Pink Apple: Sound _ Speaker Characteristics

Speaker Components

1) Cone Paper

The speaker cone is attached to the voice coil and to the outer ring of the speaker support with a frame. Because there is a definite "home" or equilibrium position for the speaker cone and there is elasticity of the mounting structure, there is inevitably a free cone resonant frequency like that of a mass on a spring

2) Edge

The edge is the outmost of the cone paper that supports the cone paper so that the body of the cone paper can vibrate vertically without changing the moving direction, which introduce sound distortion.

3) Dust cap

Circular piece inserted into a speaker diaphragm or speaker cone near the bottom, small part of the cone covering the voice coil.

4) Damper

The damper supports the connection between the voice coil and the cone.

It becomes the most part of the stiffness of a cone speaker.

5) Magnet

Magnet is the core of the magnetic circuit part, which induces the vertical movement of the voice coil according to Fleming's left-hand rule.

6) Bottom plate

The role of the bottom plate is the path of the magnetic flux without the loss of flux in air. We use steel for the bottom plate.

7) Voice coil

A voice coil is the coil of wire attached to the apex of the moving cone of a loudspeaker. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

8) Frame

The frame decides the size and shape of the speaker. This becomes the framework that supports the vibration part (cone, damper, voice coil, wire) and the magnetic circuit part (plate, magnet, bottom).

9) Gasket

Gasket plays a role of both suppressing the resonance with the metallic part when the frame and baffle were fixed and preventing the aberration of the edge by the vibration of cone paper.
