CLS0231-L152

Overview

The CLS0231-L152 is a small-size, round magnetic speaker manufactured by Same Sky. It features an 8-ohm impedance and a rated power of 1 W, with a maximum power handling of 1.5 W. The unit delivers a sound pressure level of 89 dBA at 1W/500mm. Its frequency range spans from 520 Hz to 18 kHz, with a self-resonant frequency of 650 Hz. The speaker utilizes a paper cone and Nd-Fe-B magnet, offering top porting and solder lug termination. Physical dimensions include a 23.00 mm diameter and a maximum installation height of 5.70 mm.

Feature Summary

• Utilizes a paper cone diaphragm for acoustic performance
• Features top porting configuration for sound projection
• Equipped with Nd-Fe-B magnetic structure
• Provides solder lug termination for circuit integration

Applications

• Medical electronic devices requiring compact audio output
• General-purpose consumer electronics audio modules
• Industrial control panels with status indication needs

Procurement Notes

Verify the specific suffix L152 corresponds to the required lead wire length and termination style before ordering. Confirm that the 1 W rated power aligns with your system's drive capabilities. Ensure the 5.70 mm height fits within the designated enclosure constraints. Check RoHS3 compliance requirements against local regulatory standards. Validate the 8-ohm impedance matches the amplifier output specifications.

Selection Notes

Select this model when a balance between moderate sensitivity and extended high-frequency response is required. The 18 kHz upper limit supports clearer audio reproduction compared to narrower bandwidth alternatives. Consider the paper cone material if cost-effectiveness is prioritized over synthetic durability. The top port design simplifies acoustic housing integration without rear cavity requirements.

Part Context

This component belongs to the CLS series of miniature speakers from Same Sky. The series offers various impedances and power ratings tailored for space-constrained applications. The CLS0231 variant specifically targets designs needing reliable audio feedback in portable or embedded systems. It shares physical mounting dimensions with other models in the 23 mm diameter family.

Replacement Considerations

CLS0231MA-1-L152 serves as a direct substitute with identical electrical parameters but uses a PET cone instead of paper.
