SP-3020S

Overview

The SP-3020S is a general-purpose electromagnetic speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a rated power of 1 W, with a maximum power handling of 2 W. The device delivers a sound pressure level (SPL) of 100 dBA at 1W/10cm. Its frequency range spans from 300 Hz to 5 kHz, with a self-resonant frequency of 800 Hz. The physical dimensions are 30.00 mm x 20.00 mm x 6.50 mm max height. It utilizes a polyethylene cone and NdFeB N40 magnet, operating within a temperature range of -20°C to 60°C.

Feature Summary

• High sensitivity output of 100 dBA for efficient audio reproduction
• Compact rectangular form factor suitable for space-constrained designs
• Top port location facilitates direct sound projection
• Spring-type termination allows for rapid wire lead connection

Applications

• General purpose audio output in consumer electronics
• Portable electronic devices requiring compact speakers
• Industrial control panels with audio feedback needs
• Educational toys and learning devices

Procurement Notes

Verify the specific suffix 'S' against the required datasheet, as Soberton offers variants like SP-3020 with different SPL ratings. Confirm that the 1W rating and 100 dBA efficiency match the system requirements, distinguishing it from the 1.5W/85dB SP-3020 model. Ensure the spring-type termination is compatible with the assembly process. Check environmental specifications for operation within -20°C to 60°C.

Selection Notes

Select this component when high acoustic efficiency is prioritized over raw power handling. The 100 dBA SPL makes it suitable for applications where volume is critical despite lower wattage. Compare against the SP-3020 if higher power (1.5W) is needed, accepting lower sensitivity. Ensure the 8-ohm impedance matches the amplifier output stage. The polyethylene cone material offers durability for general use cases.

Part Context

The SP-3020S belongs to Soberton's SP Micro Speaker series, designed for cost-effective audio solutions. It shares the same footprint as other models in the series but differs in magnetic strength and cone material to achieve its specific 100 dBA performance. This variant is distinct from the SP-3020, which offers higher power but lower sensitivity.

Replacement Considerations

Direct substitutes include the SP-3020 if the application can tolerate lower sensitivity (85 dBA) but requires higher power (1.5W). Verify that any replacement maintains the 8-ohm impedance and similar dimensions (30x20mm) to fit existing enclosures without mechanical modification.
