diskcones

Diskcones are a type of specialized acoustic transducer. They are characterized by a conical diaphragm that is driven at its apex by a voice coil. The conical shape of the diaphragm is designed to radiate sound over a wide angle, making diskcones suitable for applications where broad dispersion is desired.

The design of a diskcone is relatively simple, often consisting of a motor structure (magnet and voice coil) and the conical diaphragm. The diaphragm itself is typically made from lightweight yet rigid materials such as paper, plastic, or metal to ensure efficient sound reproduction and durability. The apex of the cone is attached to the voice coil, which moves back and forth when an electrical audio signal is applied. This movement causes the cone to vibrate, displacing air and creating sound waves.

Diskcones are commonly found in public address systems, musical instrument amplifiers, and some types of car audio speakers, particularly older designs. Their wide dispersion pattern is advantageous in environments where listeners are spread out, as it helps to ensure that sound reaches all areas evenly without significant loss of clarity. While they may not offer the same level of high-fidelity reproduction as some other speaker designs, their cost-effectiveness and robust construction have contributed to their enduring presence in various audio applications.
