CMS-34348N

Speakers Overview

The CMS-34348N is a general-purpose miniature loudspeaker manufactured by Same Sky. It features a square frame design with dimensions of 34.00 mm x 34.00 mm and a maximum installation height of 14.50 mm. The unit utilizes a polyurethane cone material and a neodymium iron boron magnet for efficient sound reproduction. It operates at an impedance of 8 Ohms with a rated power of 3 W and a maximum power handling of 4 W. The frequency response ranges from 304 Hz to 10 kHz, with a self-resonant frequency of 380 Hz. The speaker delivers an efficiency of 80 dBA when tested at 1 W/500mm and includes top porting for acoustic output.

Speakers Feature Summary

• Square frame construction with top porting for directional sound projection
• Polyurethane cone diaphragm paired with a neodymium magnet assembly
• General-purpose audio transducer suitable for standard electronic enclosures

Speakers Applications

• Consumer electronics requiring compact audio output
• Industrial control panels with limited space constraints
• Medical devices needing reliable miniature speakers

Speakers Procurement Notes

Verify the specific datasheet version for the CMS-34348N to confirm current manufacturing status and RoHS compliance details. Ensure that the required solder termination type matches your PCB layout, as this model uses solder lugs. Cross-reference the physical dimensions against your enclosure design to guarantee proper fitment within the 34x34 mm footprint and 14.50 mm depth limit.

Speakers Selection Notes

Select this component when a square form factor is required for aesthetic or spatial reasons in small enclosures. The 8 Ohm impedance is compatible with many standard audio amplifier outputs. Consider the 80 dBA sensitivity for applications where moderate volume levels are sufficient without excessive power consumption. The top-port design may influence internal cavity pressure requirements compared to rear-ported alternatives.

Speakers Part Context

This part belongs to the Same Sky CMS series of miniature speakers, which offers various sizes and configurations for embedded audio solutions. The manufacturer, formerly known as CUI Devices, provides these components for integration into portable and stationary electronic systems. The series emphasizes reliability and consistent acoustic performance across different environmental conditions.

Speakers Replacement Considerations

Direct substitutes must match the 34x34 mm square frame, 8 Ohm impedance, and 3 W power rating. Verify that alternative models support top porting if directional sound is critical. Check compatibility with existing mounting holes and solder terminal spacing to ensure seamless integration without redesigning the host circuit board.
