CDS-4837-54SP

Overview

The CDS-4837-54SP is a general-purpose loudspeaker manufactured by Same Sky. It features a square frame design with dimensions of 48 x 48 x 30.3 mm. The unit utilizes a Neodymium (Nd-Fe-B) magnet and a cone composed of PU and paper materials. It has a nominal impedance of 4 Ohms and a power rating of 5 Watts. The frequency response ranges from 136 Hz to 20 kHz, with a sound pressure level of 84 dB.

Feature Summary

• Square frame construction for compact mounting
• Neodymium magnet system for efficient output
• PU and paper composite cone material

Applications

• General purpose audio output devices
• Industrial equipment signaling
• Consumer electronics enclosures

Procurement Notes

Verify the specific dimensional tolerance and acoustic performance curves against the official Same Sky datasheet before integration. Confirm that the solder pad termination style matches the target PCB layout. Ensure the operating temperature range aligns with the environmental conditions of the final assembly to guarantee long-term reliability.

Selection Notes

Select this component when a square form factor is required for space-constrained designs. The 4-ohm impedance suits standard amplifier outputs. Consider the 5W power handling for moderate volume applications. The 84 dB sensitivity provides adequate audibility without excessive drive current requirements in typical consumer or industrial settings.

Part Context

This speaker belongs to the CDS series of transducers from Same Sky. It is designed as a direct replacement for legacy CUI Devices components. The product line emphasizes standardized dimensions and reliable acoustic performance for mass-produced electronic goods requiring integrated audio feedback.

Replacement Considerations

Check mechanical fitment against existing mounts. Verify electrical compatibility with the driving circuit. Compare frequency response curves to ensure acoustic similarity. Note that variations in cone material or magnet type may affect sound quality.
