CMS-3118-38E

Speakers Overview

The CMS-3118-38E is a square frame speaker manufactured by Same Sky (Formerly CUI Devices). It features a 31.6 mm body diameter and an 8 Ohm impedance with a 3 W power rating. The unit utilizes a neodymium magnet and a composite cone made of rubber and aluminum. Its self-resonant frequency is specified at 380 Hz, with a frequency response range extending from 304 Hz to 20 kHz.

Speakers Feature Summary

• Square frame design for compact integration
• Neodymium magnet construction for efficient magnetic field generation
• Composite cone material combining rubber and aluminum for durability

Speakers Applications

• General purpose audio output devices
• Compact electronic enclosures requiring small form factor speakers
• Consumer electronics with limited internal space

Speakers Procurement Notes

Verify the specific acoustic parameters against the official datasheet before procurement. Confirm that the 8 Ohm impedance and 3 W power handling align with the target amplifier or driver circuit capabilities. Ensure the square frame dimensions fit the mechanical constraints of the final assembly.

Speakers Selection Notes

Select this component when a square profile is required for aesthetic or spatial reasons. The 380 Hz self-resonant frequency indicates suitability for mid-range audio reproduction rather than deep bass applications. Consider the composite cone material if environmental resistance is a priority.

Speakers Part Context

This part belongs to the miniature speaker category within the Same Sky portfolio. It is designed for applications where standard circular speakers do not fit the available footprint. The square geometry allows for tighter packing in rectangular device housings compared to round alternatives of similar area.
