CMS-3520-18N

Speakers Overview

The CMS-3520-18N is a miniature general-purpose speaker manufactured by Same Sky. It features an oval rectangular frame design with dimensions of 35 x 20 mm and a depth of 18 mm. The component utilizes a neodymium magnet and has an impedance of 8 Ohms. It is rated for 1 W power handling and operates within a frequency range of 700 Hz to 10 kHz. The unit employs top porting for sound output and uses solder pads for electrical termination.

Speakers Feature Summary

• Compact oval rectangular frame construction suitable for space-constrained designs
• Top porting configuration for directed sound projection
• Neodymium magnet assembly for efficient magnetic flux

Speakers Applications

• Miniature audio devices requiring compact form factors
• General-purpose sound reproduction in small enclosures
• Portable electronic equipment with limited internal volume

Speakers Procurement Notes

Verify the specific acoustic performance metrics against your system requirements before procurement. Confirm that the 8 Ohm impedance matches your amplifier or driver circuit capabilities. Ensure the physical dimensions of 35 x 20 mm fit within the designated chassis space. Check for any RoHS compliance documentation if required by your manufacturing standards.

Speakers Selection Notes

Select this component when a low-profile, rectangular speaker is needed for general audio tasks. The 8 Ohm impedance is standard for many consumer electronics drivers. Consider the 1 W power rating for applications not requiring high-volume output. The top porting style may influence enclosure design compared to rear-port alternatives.

Speakers Part Context

This part belongs to the Same Sky CMS series of miniature speakers. The series offers various sizes and shapes to accommodate different design constraints. The CMS-3520-18N specifically addresses needs for rectangular footprints where circular speakers are unsuitable. It represents a balance between size, cost, and acoustic performance for basic audio functions.

Speakers Replacement Considerations

Direct substitutes must match the 35 x 20 mm footprint, 8 Ohm impedance, and top-port configuration. Verify that replacement units maintain similar frequency response characteristics from 700 Hz to 10 kHz. Ensure mechanical mounting holes align if panel mounting is required.
