CLS0301

Overview

The CLS0301 is a miniature electromagnetic speaker manufactured by Same Sky. It features an 8-ohm impedance and a rated power of 1 W, with a maximum power handling capacity of 2 W. The device utilizes a paper cone and a Neodymium Iron Boron (NdFeB) magnet to produce sound through a top-ported design. It delivers a sound pressure level of 86 dBA when driven at 1 W from a distance of 500 mm. The self-resonant frequency is specified at 550 Hz, and the operational frequency range extends from 550 Hz to 20 kHz. The unit employs a circular shape with solder pad termination for board mounting.

Feature Summary

• Top-ported acoustic design for directed sound output
• Miniature form factor suitable for space-constrained applications
• Electromagnetic transduction using NdFeB magnet technology

Applications

• Medical electronic devices requiring compact audio feedback
• Industrial control panels and instrumentation
• General-purpose consumer electronics with limited internal volume

Procurement Notes

Verify the specific manufacturing origin and compliance certifications against current regulatory requirements before integration. Confirm that the solder pad termination style matches the target PCB layout and assembly process capabilities. Ensure the operating environment remains within the specified thermal limits to maintain performance integrity and component longevity during deployment.

Selection Notes

Select this model when a low-profile, high-efficiency audio solution is required for small enclosures. The 86 dBA sensitivity provides adequate volume for alert or voice feedback in close-proximity applications. Consider the paper cone material properties regarding environmental resistance and the top-port configuration for directional sound projection needs compared to rear-vented alternatives.
