CMR-2353-2032SP

Overview

The CMR-2353-2032SP is a miniature round speaker manufactured by Same Sky. It features a 23 mm diameter frame with a depth of 5.3 mm. The unit utilizes a neodymium magnet and a PET cone to deliver audio output. It has a nominal impedance of 32 Ohms and a power handling capacity of 20 mW (0.02 W). The frequency response range spans from 20 Hz to 3.4 kHz. Electrical connections are provided via solder pads, facilitating surface mounting in compact electronic assemblies.

Feature Summary

• Compact physical dimensions suitable for space-constrained designs
• High magnetic flux density neodymium magnet construction
• Durable polyethylene terephthalate (PET) diaphragm material

Applications

• Miniature consumer electronics enclosures
• Portable personal communication devices
• Small form-factor alarm systems

Procurement Notes

Verify the specific impedance and power rating requirements against the system design specifications before procurement. Confirm that the solder pad termination method aligns with the intended assembly process. Ensure the operating frequency range meets the application's acoustic needs. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a small footprint is critical due to its 23 mm diameter and 5.3 mm depth. Consider the 32 Ohm impedance for compatibility with standard low-power audio drivers. Evaluate the 20 mW power limit to ensure it suffices for the required sound pressure level. The solder pad interface requires appropriate PCB layout considerations for reliable connection.

Part Context

This speaker belongs to the miniature category produced by Same Sky, formerly known as CUI Devices. The product line focuses on providing high-performance audio transducers in reduced physical sizes. These components are engineered for integration into modern portable devices where space optimization is a primary design constraint.

Replacement Considerations

The SP-3530A and SP-3530B are listed as substitutes in distributor databases, though they are audio plugs rather than speakers. Verify functional equivalence carefully as these are different component types.
