CLS0231MP-1

Overview

The CLS0231MP-1 is a miniature top-port speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 100 mW, with a maximum power handling of 200 mW. The device delivers a sound pressure level of 72 dBA at 100 mW/500mm. Its frequency range spans from 384 Hz to 20 kHz, with a self-resonant frequency of 480 Hz. The circular unit measures 23.00 mm in diameter and 5.00 mm in height, utilizing a PET diaphragm and Nd-Fe-B magnet.

Feature Summary

• Top-port acoustic design for direct sound projection
• Compact circular form factor suitable for space-constrained enclosures
• PET diaphragm construction for consistent audio performance
• PC pin termination for straightforward circuit board integration

Applications

• Portable consumer electronics requiring small audio output
• Medical devices needing compact acoustic signaling
• Industrial control panels with limited internal volume
• Automotive infotainment subsystems

Procurement Notes

Verify the specific suffix MP-1 against official datasheets to confirm the 100 mW rating and PET diaphragm material. Ensure compatibility with 8 Ohm amplifier outputs. Check RoHS3 compliance status for current regulatory requirements. Confirm PC pin spacing matches the target PCB footprint before ordering.

Selection Notes

Select this component when a low-profile, top-emitting speaker is required for general audio applications. The 72 dBA efficiency is moderate; higher sensitivity models exist within the same series if louder output is needed. Consider enclosure design carefully as top-port speakers rely on front cavity resonance for optimal bass response.

Part Context

This part belongs to the CLS series of miniature speakers from Same Sky. The series offers various sizes and power ratings. The CLS0231MP-1 represents the smaller 23 mm diameter option with lower power handling compared to larger variants like the CLS0301 series.

Replacement Considerations

Direct substitutes include other 23 mm top-port speakers with similar 8 Ohm impedance. Verify diaphragm material and mounting dimensions. Cross-reference with CLS0231 for higher power options, though physical dimensions remain comparable.
