SP-2811N

Overview

The SP-2811N is a general-purpose magnetic speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a rated power handling capacity of 2 watts. The device operates within a frequency range of 380 Hz to 20 kHz, with a self-resonant frequency of 380 Hz. It delivers an efficiency of 84 dBA and utilizes a top port configuration. The physical dimensions are 28.00 mm x 28.00 mm x 11.20 mm, suitable for compact audio applications.

Feature Summary

• Top square design with top port configuration
• General-purpose magnetic speaker construction
• Compact form factor suitable for space-constrained assemblies

Applications

• Consumer electronics audio output
• General purpose sound signaling
• Compact audio devices requiring standard impedance matching

Procurement Notes

Verify the specific datasheet version from Soberton Inc. or authorized distributors to confirm mechanical tolerances and thermal ratings. Ensure the application environment stays within the specified operating temperature range. Confirm that the 8-ohm impedance matches the driving circuit requirements. Check for any RoHS compliance documentation if required for your region.

Selection Notes

Select this component when a compact, low-cost speaker with standard 8-ohm impedance is needed. The 2-watt rating suits low-to-moderate volume applications. Consider the 84 dBA efficiency for system gain calculations. The top port design may influence enclosure acoustic tuning compared to rear-port alternatives.

Part Context

This part belongs to Soberton Inc.'s general-purpose speaker lineup. These components are typically used in mass-market electronics where cost and size are primary drivers. The series offers standardized mounting and electrical characteristics to simplify integration into various consumer products without custom acoustic engineering.

Replacement Considerations

Direct substitutes must match the 8-ohm impedance, 28mm x 28mm footprint, and similar sensitivity. Verify that alternative speakers maintain comparable frequency response and power handling. Mechanical mounting hole alignment should be confirmed before substitution.
