SP-1508S

Overview

The SP-1508S is a general-purpose dynamic speaker manufactured by Soberton Inc. It features an 8 Ohm impedance and an efficiency of 86 dBA. The rated power is 600 mW, with a maximum short-term power of 1.0 W. The frequency range spans from 300 Hz to 5 kHz. The unit utilizes a top port location and has a rectangular shape. Dimensions are approximately 15.00mm x 11.00mm in size with a maximum installation height of 4.00mm. Termination is provided via solder pads.

Feature Summary

• Rectangular form factor with top port configuration for mobile telephone applications
• Dynamic speaker construction using Nd-Fe-B magnet technology
• PEEK cone material for durability and acoustic performance

Applications

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

Procurement Notes

Verify the specific impedance tolerance and efficiency values against the latest manufacturer datasheet, as variations may exist between production batches. Confirm that the solder pad termination method aligns with your assembly process requirements. Ensure the rectangular dimensions fit within the designated enclosure space without interference from adjacent components or housing structures.

Selection Notes

Select this component when a compact rectangular speaker with top porting is required for mobile devices. The 8 Ohm impedance suits standard audio driver outputs. Consider the 86 dBA efficiency for adequate volume levels in small enclosures. Verify that the 300 Hz to 5 kHz frequency response meets the specific audio bandwidth needs of the target application.

Part Context

This part belongs to the SP series of micro speakers from Soberton Inc., designed primarily for mobile telephone use. The series includes various models with differing impedances and power ratings. The SP-1508S represents a general-purpose option within this lineup, balancing size constraints with acceptable acoustic performance for voice and low-fidelity audio applications.

Replacement Considerations

The SP-1508 is a related model with similar specifications but may differ in impedance (7 Ohms) and efficiency (85 dB). Verify dimensional compatibility and electrical characteristics before substitution. Other SP series variants may offer different power handling or frequency responses.
