konisäteilijästä

Konisäteilijä, also known as a conical radiator or cone radiator, is a type of loudspeaker driver designed to reproduce sound over a wide frequency range. Its distinctive feature is a cone-shaped diaphragm, typically made from paper, plastic, or metal. This cone is attached to a voice coil, which is suspended in a magnetic field. When an electrical audio signal passes through the voice coil, it causes the coil and the attached cone to vibrate. These vibrations move the surrounding air, creating sound waves that we perceive as audio.

The conical shape of the diaphragm is crucial to its acoustic performance. It allows for pistonic motion at lower frequencies, where the entire cone moves in and out uniformly, producing bass sounds. As the frequency increases, the cone can exhibit more complex vibration modes, which can contribute to the reproduction of mid-range and treble frequencies. However, these higher-order modes can also lead to distortion at very high frequencies if not carefully controlled through design and material selection.

Konisäteilijä are widely used in various audio applications, from home stereo systems and car audio to public address systems and musical instrument amplifiers. Their relatively simple design, robustness, and ability to produce a broad spectrum of sound make them a versatile and cost-effective choice for many audio reproduction needs. The size of the cone can vary significantly, with larger cones generally better suited for producing lower frequencies due to their ability to displace more air.
