CMS-15113-076SP-67

Overview

The CMS-15113-076SP-67 is a rectangular micro speaker manufactured by Same Sky. It features a 6 Ohm impedance and a 700 mW power rating, with a maximum capacity of 1 W. The device delivers a sound pressure level of 92 dBA at 700mW/100mm. Its self-resonant frequency is 600 Hz, and it operates within a frequency range of 100 Hz to 20 kHz. Dimensions are 15.00 mm in length, 11.00 mm in width, and 3.00 mm in height. It utilizes solder pad termination and offers IP67 protection against dust and water.

Feature Summary

• IP67 rated for dust and water resistance
• Top port acoustic design
• Nd-Fe-B magnet construction
• PET diaphragm material

Applications

• Consumer electronics requiring sealed audio components
• Medical devices needing moisture-resistant speakers
• Industrial equipment with dust exposure risks
• Portable gadgets demanding compact form factors

Procurement Notes

Verify the specific suffix -67 to confirm IP67 sealing capabilities, as standard variants may lack this rating. Ensure the PCB layout accommodates the 15mm x 11mm footprint and solder pad termination style. Confirm that the operating environment stays within the specified temperature range and does not exceed the 700 mW continuous power rating to maintain reliability.

Selection Notes

Select this component when environmental sealing is critical for the audio output stage. The top port configuration allows for flexible mounting orientations where side ports might be obstructed. Consider the 6 Ohm impedance for amplifier matching and verify that the 92 dBA efficiency meets the required volume levels for the intended application space without excessive power draw.

Part Context

This model belongs to the CMS series of micro speakers from Same Sky. It represents a specialized variant designed for harsh environments compared to standard open-back speakers. The integration of IP67 sealing distinguishes it from basic audio components, making it suitable for applications where standard speakers would fail due to ingress of liquids or particulates.

Replacement Considerations

Direct substitutes must match the 15x11mm dimensions, 6 Ohm impedance, and IP67 rating. Verify that alternative models support the same solder pad termination and top port orientation. Check if competitor parts offer equivalent PET diaphragm materials and Nd-Fe-B magnets to ensure similar acoustic performance and durability.
