Overview
The CDS-4553-16-SP is a general-purpose round frame loudspeaker manufactured by Same Sky. It features a 45 mm diameter with a 1 W power handling capacity and a nominal impedance of 16 Ohms. The unit utilizes a neodymium magnet and a PET cone for acoustic performance. Key electrical parameters include a resonant frequency range of 400 Hz to 6 kHz and a sound level of 80 dB. The mounting depth is specified at 2.9 mm, making it suitable for compact audio applications requiring reliable transducer output.
Feature Summary
- Utilizes a neodymium magnet structure for efficient magnetic flux generation within a compact form factor.
- Incorporates a PET (Polyethylene Terephthalate) cone material designed for balanced acoustic response and durability.
- Features a round frame design optimized for standard mounting configurations in consumer electronics.
Applications
- General purpose audio output devices
- Compact electronic enclosures requiring low profile speakers
- Consumer electronics audio modules
Procurement Notes
Verify the specific impedance and power rating requirements against your circuit design before procurement. Confirm that the 45 mm diameter and 2.9 mm mounting depth fit within the mechanical constraints of the target enclosure. Ensure compatibility with the 16 Ohm load for amplifier matching. Check current availability status as component lifecycles may change.
Selection Notes
Select this model when a 16 Ohm impedance is required for the audio output stage. The 1 W power rating suits low-volume or indicator audio signals rather than high-fidelity music reproduction. Consider the 80 dB sound level adequacy for the intended listening environment. The 400 Hz to 6 kHz frequency range defines the audible bandwidth limitations for voice or simple tone applications.
Part Context
This component belongs to the Same Sky speaker series, specifically designed for general-purpose audio transduction. It represents a standard solution for integrating audio capabilities into small form-factor devices where space is limited but basic sound output is necessary.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify mechanical dimensions and electrical specifications carefully if considering alternative manufacturers.
