K 20.40 - 8 OHM

Speakers Overview

The Visaton K 20.40 - 8 OHM is a miniature loudspeaker designed for audio reproduction in compact electronic devices. It features an 8-ohm nominal impedance and a 20 mm diaphragm diameter, allowing for integration into space-constrained enclosures. The unit has a rated power handling capacity of 0.1 W and delivers a sound pressure level of 73 dB measured at one watt and one meter distance. With a resonance frequency of approximately 1.5 kHz and a total height of 6.5 mm, this component provides efficient acoustic output suitable for small-scale applications requiring clear mid-range performance.

Speakers Feature Summary

• Compact physical dimensions facilitate installation in tight spaces
• Paper cone construction ensures balanced acoustic characteristics
• Low profile design supports integration into slim device housings

Speakers Applications

• Miniature portable audio equipment
• Small intercom systems
• Compact alarm devices

Speakers Procurement Notes

Verify the specific suffix codes on the datasheet to confirm exact impedance and mechanical tolerances before ordering. Ensure that the required mounting configuration matches the available terminal types. Cross-reference the manufacturer's latest documentation to confirm current availability status and any potential supply chain constraints affecting lead times.

Speakers Selection Notes

Choose this model when space limitations restrict the use of larger drivers and low power consumption is critical. Evaluate the enclosure volume against the speaker's Thiele-Small parameters to ensure adequate bass response. Consider the operating temperature range and environmental exposure requirements to determine if additional protective measures are necessary for long-term reliability.

Speakers Part Context

This component belongs to Visaton's series of miniature dynamic loudspeakers engineered for consumer electronics. These units typically utilize paper cones and ferrite magnets to achieve high efficiency within minimal footprints. The product line focuses on providing reliable audio solutions for devices where size and weight are primary design constraints rather than high-fidelity music reproduction.

Speakers Replacement Considerations

Direct substitutes must match the 8-ohm impedance and 20 mm diameter to maintain circuit compatibility and fit. Verify that alternative models offer similar sensitivity ratings to preserve volume levels. Check mechanical mounting hole patterns and depth restrictions to ensure seamless integration without modifying the existing chassis.
