SP-1504

Overview

The SP-1504 is a dynamic speaker manufactured by Soberton Inc. It features an elliptical shape with dimensions of 30.00mm x 20.00mm and a maximum height of 5.20mm. The unit utilizes a paper cone and Nd-Fe-B N40 magnet. It has an impedance of 8 ohms and operates within a frequency range of 300 Hz to 8 kHz, with a self-resonant frequency of 500 Hz. The sound pressure level is 85 dB SPL. Rated power is 1.5 W with a maximum power handling of 2 W. It uses wire leads for termination and functions between -20°C and 60°C.

Feature Summary

• Utilizes a paper cone diaphragm and Nd-Fe-B N40 magnetic system for acoustic output.
• Features an elliptical physical form factor designed for compact integration.
• Employs wire lead termination for direct circuit connection.

Applications

• General purpose audio reproduction
• Compact electronic device integration

Procurement Notes

Verify the specific manufacturer datasheet to confirm exact electrical tolerances and mechanical drawings. Ensure the wire lead configuration matches the target PCB or harness design. Confirm that the operating temperature range of -20°C to 60°C aligns with the intended environmental conditions. Validate the 8-ohm impedance requirement against the amplifier output specifications.

Selection Notes

Select this component when a small elliptical footprint is required. The 8-ohm impedance suits standard low-voltage audio drivers. The 1.5W rating indicates suitability for low-power applications. Consider the paper cone material characteristics for specific tonal requirements. Verify space constraints against the 5.20mm maximum height limit.

Part Context

This part belongs to the SP Micro Speaker series from Soberton Inc. The series focuses on compact dynamic speakers for mobile and portable devices. The SP-1504 represents a specific size variant within this lineup, distinguished by its elliptical geometry and paper cone construction compared to other rectangular or circular models in the family.
