SP-1511S-1

Overview

The SP-1511S-1 is a rectangular dynamic speaker unit manufactured by Soberton Inc., designed for mobile telephone applications. It features an 8 Ohm impedance and operates within a frequency range of 400 Hz to 5 kHz. The component has a rated noise power of 700 mW and a maximum short-term power handling capacity of 900 mW when measured in a 1cc box. It delivers an average sound pressure level of 83 dB SPL at 1 kHz, measured with a baffle. The speaker utilizes a PEEK cone and Nd-Fe-B magnet, with dimensions of 15.00mm x 11.00mm and a maximum height of 4.00mm.

Feature Summary

• Rectangular form factor with top port configuration suitable for compact mobile device integration
• Utilizes PEEK cone material and Nd-Fe-B magnetic structure for acoustic performance
• Designed for general purpose audio output in mobile telephone environments

Applications

• Mobile telephone audio output
• General purpose dynamic speaker units
• Compact electronic devices requiring small form factor speakers

Procurement Notes

Verify the specific suffix designation (e.g., -1) against official Soberton documentation to confirm exact electrical parameters such as sensitivity and power ratings, as variations exist within the SP-1511S series. Ensure compatibility with target enclosure acoustics, particularly regarding the 1cc box measurement conditions specified for maximum power handling. Confirm package termination type matches assembly requirements.

Selection Notes

Select this model for applications requiring a small rectangular footprint with top-port orientation. Consider the 8 Ohm impedance and 700 mW rating for low-power mobile audio circuits. Evaluate the 400 Hz to 5 kHz frequency response against target audio fidelity requirements. Verify that the physical dimensions fit within the designated chassis space while allowing for the required mounting height.

Part Context

The SP-1511S-1 belongs to the SP Micro Speaker series from Soberton Inc., specifically engineered for mobile communication devices. This series emphasizes compactness and reliability for consumer electronics. The part represents a standard dynamic driver solution within the manufacturer's portfolio for portable audio applications.

Replacement Considerations

SP-1511S-3 and SP-1511S are related models within the same series but may differ in sensitivity or power ratings. Verify electrical equivalence before substitution.
