WSPM-3020W

Overview

The WSPM-3020W is a general-purpose oval speaker from the WSPH series by Soberton Inc. It features an 8-ohm impedance and a rated input power of 1.5 watts. The device operates within a frequency range of 1.75 kHz to 20 kHz, with a self-resonant frequency of 1.75 kHz. It delivers a sound pressure level of 99 dB and utilizes NdFeB magnetic material. Physical dimensions are 30mm x 20mm x 7.5mm, offering an IP67 ingress rating for environmental protection.

Feature Summary

• IP67 ingress protection rating for environmental sealing
• Oval shape design with top port configuration
• NdFeB magnetic material construction

Applications

• Wide-spectrum audio applications requiring high sensitivity
• Enclosed speaker box assemblies
• General purpose sound output devices

Procurement Notes

Verify the specific suffix (e.g., W) against official Soberton documentation to confirm connector type and wire length specifications. Ensure the IP67 rating aligns with the intended environmental exposure requirements. Confirm that the 1.5W power rating meets the system's thermal and electrical constraints before finalizing procurement.

Selection Notes

Select this component when a compact oval form factor is required alongside high acoustic efficiency. The 99dB sensitivity supports loud output in small enclosures. Verify that the 1.75kHz lower frequency limit suits the application, as it may not reproduce deep bass frequencies effectively without additional processing or larger drivers.

Part Context

This model belongs to the WSPH series, which emphasizes ruggedness and environmental sealing. Soberton Inc. manufactures electromagnetic switching components and sound devices, including magnetic transducers and speakers. This specific unit represents their general-purpose line designed for integration into various electronic assemblies.

Replacement Considerations

Direct substitutes must match the 30x20mm oval footprint, 8-ohm impedance, and IP67 rating. Check datasheets for compatible models within the WSPH series or equivalent oval speakers from other manufacturers that meet the 1.5W power and 99dB SPL requirements.
