SPKM.15.8.A

Overview

The SPKM.15.8.A is a miniature dynamic speaker manufactured by Taoglas Limited, designed for high-fidelity audio applications in compact enclosures. It features an 8-ohm impedance and a power handling capacity of 0.7W (700mW), with official specifications citing a sensitivity of 85dBA at 1kHz/1W/10cm. The frequency response spans from 100 Hz to 11 kHz, ensuring clear reproduction across the audible spectrum. Physically, it measures 15 mm in diameter by 3.7 mm in height, utilizing a neodymium magnet system. The component employs a top-port design with round wire leads, facilitating straightforward integration into space-constrained electronic devices while maintaining distortion-free performance.

Feature Summary

• Miniature form factor with 15mm diameter and 3.7mm height for tight spatial integration
• High sensitivity output delivering clear audio fidelity with low distortion
• Neodymium magnet construction providing efficient magnetic flux density
• Top-port acoustic design optimized for directional sound projection

Applications

• Portable consumer electronics requiring small footprint speakers
• Medical devices needing reliable audio feedback components
• Industrial control panels with limited internal volume
• Smart home IoT devices requiring integrated audio output

Procurement Notes

Verify the specific suffix configuration against your schematic requirements, as Taoglas may offer variations in lead type or mounting style within the SPKM series. Confirm that the 8-ohm impedance aligns with your amplifier output stage to prevent mismatch issues. Ensure the mechanical dimensions fit within your enclosure constraints, particularly the 3.7mm height profile. Check for any RoHS compliance documentation if required by your regional regulations. Always reference the latest manufacturer datasheet for pinout and acoustic center details before finalizing the bill of materials.

Selection Notes

Select this component when space is severely restricted but high audio quality is mandatory. The 15mm size offers a balance between portability and acoustic performance compared to smaller 10mm alternatives. Consider the top-port design if directional sound is preferred over omnidirectional dispersion. The 8-ohm impedance is standard for many low-power audio amplifiers, simplifying driver selection. Evaluate the 11 kHz upper frequency limit to ensure it meets the treble requirements of your specific application, noting that it may not cover ultra-high frequencies beyond this range.

Part Context

The SPKM.15.8.A belongs to Taoglas's SPKM series of miniature dynamic speakers. This series is engineered for applications demanding high sensitivity and low total harmonic distortion in minimal package sizes. The SPKM line typically includes variants ranging from 10mm to larger diameters, allowing designers to scale audio output based on available space. These components are positioned as general-purpose audio transducers suitable for modern portable and embedded systems where traditional speakers are too bulky.

Replacement Considerations

Direct substitutes must match the 15mm diameter, 8-ohm impedance, and similar frequency response range. Verify that alternative components support the same 0.7W power rating and utilize neodymium magnets for comparable efficiency. Ensure the replacement maintains the top-port acoustic architecture if directional sound is critical. Cross-reference mechanical drawings to confirm height compatibility, as even minor deviations can affect enclosure fitment.
