SP-2805

Overview

The SP-2805 is an electromagnetic dynamic speaker manufactured by Soberton Inc. It features a round shape with a diameter of 28mm and utilizes contact termination. The component has an impedance of 8 ohms and a rated power handling capacity of 300mW. It delivers a sound pressure level of 91dB and operates within a frequency range starting at 600Hz. The design incorporates top porting for acoustic output.

Feature Summary

• Electromagnetic dynamic transducer technology
• Top port acoustic configuration
• Round physical form factor

Applications

• General purpose audio output devices
• Embedded electronic systems requiring compact speakers

Procurement Notes

Verify the specific datasheet revision, as Soberton Inc. documents indicate edition A/2016. Confirm that the required sound pressure deviation tolerance aligns with the specified ±3dB limit from initial values. Ensure the application environment supports the 8-ohm impedance and 300mW power rating without exceeding thermal or electrical limits defined in the official specifications.

Selection Notes

Select this component when a compact 28mm round speaker is required for general-purpose applications. The 8-ohm impedance and 300mW rating suit low-power embedded designs. Verify that the 600Hz lower frequency limit meets the acoustic requirements, as this model does not cover full-range bass frequencies below this threshold.

Part Context

This part belongs to the Soberton Inc. speaker series, which includes variants such as the SP-2805-1. These components are classified as dynamic speakers designed for reliable performance in consumer electronics. The SP-2805 specifically emphasizes standard impedance and moderate power handling for typical signal amplification stages.

Replacement Considerations

The SP-2805-1 is a documented variant from the same manufacturer. Verify if the -1 suffix denotes identical electrical characteristics or specific mechanical differences before substitution.
