SP-2804L

Overview

The SP-2804L is a general-purpose dynamic speaker manufactured by Soberton Inc. It features a round shape with top port location and wire termination. The unit has an impedance of 4 ohms and supports input power ratings of 1.5 W or 2.0 W. It delivers a sound pressure level of 92 dB (+/- 3 dB) at a frequency of 450 Hz (+/- 20%). The cone material is polyester (PET), and the magnet is composed of Nd-Fe.

Feature Summary

• Round shape design with top port location
• Wire termination for connection
• Nd-Fe magnet construction

Applications

• General purpose audio output
• Embedded device speakers
• Consumer electronics audio modules

Procurement Notes

Verify the specific datasheet version to confirm if the rated power is strictly 1.5W or 2.0W, as sources vary. Ensure the 4-ohm impedance matches the amplifier output requirements. Confirm the wire termination type suits the assembly process. Check RoHS compliance status for regulatory adherence in target markets.

Selection Notes

Select this component when a compact, round speaker with 4-ohm impedance is required. The 92 dB sensitivity indicates moderate efficiency suitable for low-power applications. Consider the physical dimensions and mounting constraints associated with the round shape and top port configuration during PCB layout.

Part Context

This part belongs to the SP series of dynamic speakers from Soberton Inc. Similar models include the SP-2805, which shares the same manufacturer lineage. The series typically offers various impedance and sensitivity options for different audio application needs within embedded systems.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternatives based on matching 4-ohm impedance, similar sensitivity around 92 dB, and compatible physical dimensions. Verify that any replacement maintains the wire termination style and round form factor.
