SPKM.28.8.A

Overview

The SPKM.28.8.A is a general-purpose dynamic audio speaker manufactured by Taoglas Limited. It features an 8-ohm impedance and a power handling capacity of 1 watt, with an RMS rating of 0.5 watts. The unit has a round shape with a diameter of 28 mm and a height of 5.1 mm. Its frequency response ranges from 10 Hz to 11 kHz, while other sources specify a range of 100 Hz to 10 kHz. The speaker utilizes neodymium magnet material and offers a sound pressure level (efficiency) of 89 dB when tested at 500 mW/100 mm.

Feature Summary

• Compact round design with 28 mm diameter and 5.1 mm height for space-constrained integration
• Neodymium magnet construction for efficient acoustic performance
• General-purpose dynamic driver suitable for standard audio output applications

Applications

• Electronic devices requiring miniature audio output
• Internet of Things (IoT) hardware
• Portable consumer electronics

Procurement Notes

Verify the specific datasheet version to confirm if the frequency response is rated at 10 Hz or 100 Hz lower limit, as documentation varies. Confirm the exact power rating context (1 W vs 0.5 W RMS) against the target application requirements. Ensure the 8-ohm impedance matches the amplifier output stage. Check for RoHS compliance status in the latest manufacturing data.

Selection Notes

Select this component for designs prioritizing low profile and small footprint over wide-bandwidth fidelity. The 8-ohm impedance requires matching with compatible audio drivers. Consider the 89 dB sensitivity for volume requirements. Evaluate if the 28 mm diameter fits within the enclosure constraints. Verify thermal management capabilities given the 1 W maximum power handling.

Part Context

This model belongs to Taoglas Limited's dynamic audio speaker portfolio, specifically designed for miniaturized applications. It serves as a compact alternative to larger speakers in IoT and portable device sectors. The product line emphasizes high efficiency and robust construction using neodymium magnets to deliver clear audio in restricted spaces.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must verify mechanical dimensions and electrical parameters when considering alternatives from other manufacturers.
