CMS-160925-078L100A

Speakers Overview

The CMS-160925-078L100A is a miniature electromagnetic speaker manufactured by Same Sky. It features a rectangular frame measuring 16 mm x 9 mm with a height of 2.50 mm. The unit operates at an impedance of 8 Ohms and has a rated power of 0.7 W, with a maximum power handling of 1 W. It utilizes a Neodymium Iron Boron (NdFeB) magnet and a PEEK cone material. The self-resonant frequency is 550 Hz, and it provides a sound pressure level of 90 dBA. Electrical connection is achieved via wire leads equipped with a connector.

Speakers Feature Summary

• Utilizes a high-strength neodymium magnet for efficient acoustic output in a compact form factor.
• Features a durable PEEK cone material designed to withstand thermal stress and mechanical fatigue.
• Incorporates integrated wire leads with a connector for simplified assembly and reduced wiring complexity.

Speakers Applications

• Portable electronic devices requiring low-profile audio output
• Medical equipment needing reliable acoustic signaling
• Industrial control panels for status indication

Speakers Procurement Notes

Verify the specific connector type and wire lead length required for your application, as these are critical integration parameters. Confirm that the 8 Ohm impedance matches your amplifier or driver circuit capabilities. Ensure the operating temperature range aligns with your device's environmental conditions. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the physical dimensions against your enclosure design constraints.

Speakers Selection Notes

Select this component when a rectangular footprint is necessary to maximize surface area usage. The PEEK cone offers superior durability compared to standard Mylar cones in high-temperature environments. The integrated connector simplifies the bill of materials by eliminating separate header requirements. Consider the 90 dBA output sufficient for general alerting but verify audibility needs for noisy environments.

Speakers Part Context

This model belongs to the CMS series of miniature speakers from Same Sky. It shares the same 16x9mm rectangular frame geometry as other variants like the CMS-160925-078S. The primary distinction lies in the termination method; this variant uses wire leads with a connector instead of spring terminals. It serves as a specialized option for automated assembly processes where plug-in connections are preferred over soldering or press-fit methods.

Speakers Replacement Considerations

The AS01608MS-SC9-WP-R from PUI Audio is listed as a similar replacement. Verify dimensional compatibility and electrical specifications before substitution. Note that the original CMS-160925-078S uses spring terminals, which differs from the wire lead connector of this model.
