CMS-160925-078S

Speakers Overview

The CMS-160925-078S is a general-purpose rectangular speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 700 mW, with a maximum power handling capacity of 1 W. The device delivers a sound pressure level of 90 dBA at 700 mW/100mm. Its frequency response ranges from 100 Hz to 20 kHz, with a self-resonant frequency of 550 Hz. The physical dimensions are 16.00 mm in length, 9.00 mm in width, and a maximum installation height of 2.50 mm. Top porting is utilized for acoustic output.

Speakers Feature Summary

• Rectangular form factor with top port design for directional sound projection
• Utilizes Nd-Fe-B magnetic structure for efficient audio conversion
• Polyester (PET) cone material ensures durability and consistent performance
• Spring-type termination facilitates rapid mechanical integration

Speakers Applications

• General purpose audio indication in consumer electronics
• Audible alerts in industrial control panels
• Status signaling in medical devices
• Feedback mechanisms in home appliances

Speakers Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm exact acoustic and electrical tolerances. Ensure that the spring-type termination method aligns with the target assembly process. Confirm RoHS3 compliance status if required by regional regulations. Cross-reference the 16x9mm outline dimensions with the enclosure design to ensure proper fitment and acoustic sealing.

Speakers Selection Notes

Select this component when a compact rectangular speaker with top porting is required. The 8 Ohm impedance suits standard low-voltage driver circuits. The 700 mW rating provides adequate volume for proximity-based alerts. Consider the 100 Hz lower frequency limit when designing for bass-heavy applications, as this unit is optimized for mid-to-high frequency reproduction.

Speakers Part Context

This model belongs to the CMS series of speakers from Same Sky, formerly CUI Devices. The series offers various sizes and configurations for embedded audio needs. The CMS-160925 variant specifically denotes the 16x9mm footprint. This series is designed for cost-effective mass production while maintaining reliable acoustic performance in space-constrained electronic assemblies.

Speakers Replacement Considerations

AS01608MS-SC9-WP-R by PUI Audio is documented as a similar alternative. Verify impedance, SPL, and dimensional compatibility before substitution.
