SP-1003

Overview

The SP-1003 is a dynamic electromagnetic speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a rated power of 300 mW. The device operates within a frequency range of 300 Hz to 8 kHz, with a resonant frequency of 1.35 kHz. Its physical dimensions include a diameter of 10 mm and a height of 2.9 mm. The unit utilizes a top round port configuration and provides a sound pressure level of 80 dB.

Feature Summary

• General purpose dynamic electromagnetic construction
• Top round port location for acoustic output
• Compact circular form factor with wire leads

Applications

• Consumer electronics audio output
• Portable device speakers
• General purpose acoustic signaling

Procurement Notes

Verify the specific datasheet version to confirm active status and exact dimensional tolerances. Ensure compatibility with driving circuits regarding the 8-ohm impedance and 300 mW power rating. Confirm that the 300 Hz to 8 kHz frequency response meets application requirements. Check for lead-free compliance if environmental regulations apply.

Selection Notes

Select this component when a compact, low-power speaker is required for general audio applications. The 10 mm diameter suits space-constrained designs. Consider the limited high-frequency extension above 8 kHz when evaluating audio fidelity needs. The top-port design influences mounting orientation and enclosure integration strategies.

Part Context

This component belongs to the SP Micro Speaker series from Soberton Inc., designed for small-scale electronic devices. It represents a standard dynamic driver solution for budget-conscious or size-limited projects requiring basic audio reproduction capabilities without complex amplification requirements.

Replacement Considerations
