SPKM.36.4.B

Overview

The SPKM.36.4.B is a miniature dynamic audio speaker manufactured by Taoglas Limited, designed for integration into electronic and IoT devices. It features a 36mm diameter form factor with a 4 Ohm impedance rating and a power handling capacity of 1W RMS. The unit operates within a frequency range of 100 Hz to 10 kHz and achieves an IP67 ingress protection rating, ensuring dust tightness and waterproofing capabilities. Termination is provided via wire leads, facilitating connection to standard audio circuits.

Feature Summary

• Compact 36mm design suitable for space-constrained electronics
• IP67 rated for dust and water resistance
• Dynamic audio transducer technology

Applications

• Internet of Things (IoT) devices
• Electronic equipment requiring sealed audio output
• General purpose miniature speaker applications

Procurement Notes

Verify the specific termination style and lead length requirements against your assembly drawings before ordering. Confirm that the 4 Ohm impedance aligns with your amplifier output specifications to ensure optimal performance and prevent damage. Ensure the IP67 rating meets the environmental exposure standards required for your final product deployment scenario.

Selection Notes

Select this component when a robust, sealed audio solution is required in a compact footprint. The 1W RMS power handling supports moderate volume levels for general notification or voice playback. Consider the IP67 rating if the device will be exposed to moisture or dust. Verify compatibility with available mounting space given the 35.70mm diameter dimension.

Part Context

This part belongs to Taoglas Limited's portfolio of miniature speakers engineered for modern electronics. It represents a specialized audio transducer category distinct from RF antennas, focusing on acoustic output rather than signal transmission. The series targets applications demanding reliability and environmental sealing in small form factors.

Replacement Considerations

Check for alternative models within the same manufacturer series that may offer different impedance values or power ratings. Ensure any substitute maintains the required IP67 rating and physical dimensions to fit existing enclosures without modification.
