2840

Overview

The Visaton 2840 is a miniature loudspeaker driver featuring a 40 mm diameter and an 8 Ω nominal impedance. It utilizes a paper cone with a rectangular plastic basket and incorporates a neodymium magnet to achieve compact dimensions of approximately 40 mm in diameter and 4.5 mm in height. Designed for general purpose applications, it supports a power handling capacity of 1 W. The frequency response typically spans from 350 Hz to 6 kHz, making it suitable for mid-range reproduction tasks.

Feature Summary

• Compact physical profile enabled by neodymium magnet technology
• Paper cone diaphragm construction for acoustic performance
• Rectangular plastic basket housing for structural support

Applications

• Miniature speaker assemblies
• General purpose audio reproduction
• Speech transmission systems

Procurement Notes

Verify the specific electrical parameters against the manufacturer's current datasheet before integration. Confirm mechanical mounting requirements match the design constraints. Ensure the 8 Ω impedance aligns with the amplifier output stage. Check for any recent revisions to the component specifications that may affect compatibility.

Selection Notes

Select this component when space constraints are critical due to its small form factor. Consider the 1 W power rating for low-volume applications. The 350 Hz to 6 kHz range defines its suitability for mid-range frequencies rather than full-range or bass-heavy roles. Evaluate the paper cone characteristics for desired tonal qualities.

Part Context

This model belongs to Visaton's series of miniature speakers designed for tight spatial environments. It represents a balance between acoustic output and physical size, leveraging advanced magnetic materials to reduce depth while maintaining necessary drive capabilities for small enclosures.

Replacement Considerations

Direct substitutes must match the 40 mm diameter, 8 Ω impedance, and similar frequency response. Verify mechanical mounting hole patterns and depth constraints. Alternative models with different magnet types may require circuit adjustments.
