K 57 C - 8 OHM

Speakers Overview

The Visaton K 57 C - 8 OHM is a miniature electromagnetic speaker featuring an 8-ohm impedance and a 2-watt power rating. It utilizes a transparent Mylar diaphragm and a neodymium magnet to achieve a sound pressure level of 87 dB. The unit operates within a frequency range of 350 Hz to 6.8 kHz, with a resonant frequency at 350 Hz. Its compact oval design measures 57 mm in length, 17 mm in width, and 17 mm in depth, weighing approximately 4 grams. The component supports panel mounting via solder pads and functions reliably between -25°C and +70°C.

Speakers Feature Summary

• Features a waterproofed transparent Mylar membrane for durability
• Incorporates a lightweight neodymium magnet for efficient performance
• Designed with a low installation height for space-constrained applications

Speakers Applications

• Signal output in industrial machines
• Compact audio devices requiring minimal depth
• Equipment needing waterproofed acoustic components

Speakers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct impedance and terminal configuration. Confirm that the package type matches your assembly requirements, as bulk packaging may require separate handling procedures. Cross-reference the RoHS compliance status with local regulatory standards before finalizing procurement orders.

Speakers Selection Notes

Select this model when a flat profile and water resistance are critical constraints. The neodymium magnet offers higher efficiency compared to standard ferrite alternatives in similar form factors. Ensure the driving circuit can handle the 8-ohm load without exceeding the 2-watt thermal limit during continuous operation.

Speakers Part Context

This component belongs to the Visaton K series of miniature speakers. It is engineered for integration into tight spaces where traditional speakers cannot fit. The design prioritizes mechanical robustness and acoustic clarity in small enclosures, serving as a direct replacement for legacy plastic-diaphragm units in modern electronic assemblies.

Speakers Replacement Considerations

The K 57 FL - 8 Ohm serves as a functional substitute, sharing identical dimensions and electrical characteristics but utilizing a metal basket instead of a plastic frame. Verify that the mounting hole patterns align perfectly to avoid structural modifications during installation.
