SP-1813S-1

Overview

The SP-1813S-1 is an electromagnetic dynamic speaker unit manufactured by Soberton Inc., designed for mobile phone applications. It features a rectangular top-port configuration with wire lead installation. Key electrical parameters include an impedance of 8 ohms and a rated power of 500 mW. The frequency range spans from 200 Hz to 3.4 kHz, with a resonant frequency of 800 Hz. Efficiency is specified at 91 dBA when tested at 800 mW over a distance of 100 mm.

Feature Summary

• Electromagnetic dynamic construction optimized for compact mobile devices
• Top rectangular port design for directional sound projection
• Wire lead termination for flexible circuit integration

Applications

• Mobile phone audio output
• Portable communication devices
• Compact consumer electronics speakers

Procurement Notes

Verify the specific suffix '-1' against official Soberton documentation to confirm exact efficiency and dimensional tolerances, as datasheets may vary between revisions. Ensure compatibility with 8-ohm driver circuits. Confirm RoHS compliance status through current manufacturer certificates before final procurement decisions.

Selection Notes

Select this component for applications requiring a small form factor with moderate power handling. The 8-ohm impedance matches standard audio amplifier outputs. Consider the 200 Hz lower frequency limit for voice-centric applications rather than full-range music reproduction. Verify physical mounting constraints due to the rectangular shape.

Part Context

This model belongs to Soberton's series of dynamic speakers intended for portable electronics. It shares the general electromagnetic architecture with other models in the SP-18xx series but differs in specific tuning and efficiency metrics. The product line focuses on cost-effective solutions for mass-market mobile devices.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate generic 8-ohm, 500 mW rectangular speakers with similar frequency ranges only after verifying mechanical fit and acoustic performance requirements.
