CMS-151103-16SP

Speakers Overview

The CMS-151103-16SP is a miniature rectangular speaker manufactured by Same Sky. It features a 6 Ohm impedance and a rated power of 700 mW, with a maximum power handling capacity of 1 W. The device operates within a frequency range of 100 Hz to 20 kHz and delivers a sound pressure level of 92 dBA when tested at 700 mW/100mm. Its physical dimensions are 15.00 mm in length, 11.00 mm in width, and a maximum installation height of 3.00 mm. The unit utilizes a polyester (PET) cone and an Nd-Fe-B magnet, offering top porting for acoustic output.

Speakers Feature Summary

• IP67 rated enclosure providing dust and waterproof protection for reliable operation in harsh environments.
• Top port design facilitates direct acoustic coupling and efficient sound projection from the upper surface.
• Constructed with a neodymium iron boron magnet and polyester diaphragm for consistent audio performance.

Speakers Applications

• Electronic components for medical applications
• Waterproof audio solutions requiring sealed enclosures
• General purpose miniature speaker integration

Speakers Procurement Notes

Verify the specific suffix configuration against the official Same Sky datasheet to ensure correct impedance and sensitivity ratings. Confirm RoHS compliance status through the manufacturer's environmental documentation prior to finalizing component selection for regulated markets.

Speakers Selection Notes

Select this model when IP67 sealing is required for audio output in compact spaces. The 6 Ohm impedance suits standard low-voltage driver circuits. Ensure mechanical clearance accommodates the 3.00 mm height limit and verify that the 100 Hz lower frequency response meets application requirements.

Speakers Part Context

This component belongs to the CMS-151103 series of miniature speakers from Same Sky, formerly CUI Devices. The series focuses on small form factor audio solutions suitable for portable electronics and embedded systems where space constraints and environmental sealing are critical design factors.

Speakers Replacement Considerations

Cross-reference with CMS-15113-076SP-67 for similar dimensional and electrical characteristics. Verify mounting hole patterns and terminal types before substituting to ensure mechanical compatibility.
