SP-1511S-6

Overview

The SP-1511S-6 is a dynamic speaker unit manufactured by Soberton Inc., designed for mobile telephone applications. It features an 8 Ohm impedance and a rated power of 500 mW, with a maximum short-term power of 800 mW. The device delivers an efficiency of 82 dBA SPL at 100 mW/10cm. Its frequency range spans from 300 Hz to 5 kHz. The physical dimensions are 15.00 mm in length, 11.00 mm in width, and a maximum installation height of 4.00 mm. The speaker utilizes a PEEK cone and Nd-Fe-B magnet, with spring-type termination.

Feature Summary

• Utilizes a polyether ether ketone (PEEK) cone for diaphragm construction
• Incorporates neodymium iron boron (Nd-Fe-B) magnetic technology
• Features top port location on a rectangular housing
• Employs spring-type termination for circuit connection

Applications

• Mobile telephone audio output
• General purpose sound reproduction
• Embedded microcontroller audio interfaces

Procurement Notes

Verify the specific suffix designation against official Soberton documentation to confirm exact electrical tolerances and mechanical fit. Ensure the spring-type termination matches the target PCB layout requirements. Confirm that the 8 Ohm impedance aligns with the driving circuit's output capabilities. Cross-reference the 500 mW rated power with thermal management constraints in the final assembly.

Selection Notes

Select this component when a compact rectangular form factor is required for mobile devices. The 8 Ohm impedance suits standard low-voltage audio drivers. The 82 dBA efficiency provides adequate volume for personal listening. Consider the 300 Hz to 5 kHz frequency response for voice-centric or limited-bandwidth audio needs rather than full-range music reproduction.

Part Context

This part belongs to the SP-1511S series of dynamic speakers from Soberton Inc. The series is engineered specifically for portable electronics where space is constrained. The model number indicates specific variations within the family, primarily differing in suffix codes which may denote minor manufacturing revisions or packaging differences without altering core acoustic performance.

Replacement Considerations

Direct substitutes include other models within the SP-1511S series, such as SP-1511S-4 or SP-1511S-5, provided they share identical mounting dimensions and impedance characteristics. Verify that any replacement maintains the same spring-type termination style to ensure compatibility with existing board designs.
