Overview
The SP-4022 is a general-purpose dynamic speaker manufactured by Soberton Inc. It features a rated input power of 5.0/6.0 W and an impedance of 4 Ohms with a tolerance of plus or minus 15%. The device produces a sound pressure level of 80 dB, measured with a tolerance of plus or minus 3 dB. Its operating frequency is specified at 350 Hz, allowing for plus or minus 20% variation. The component utilizes a pad termination method for surface mounting.
Feature Summary
- Dynamic speaker design suitable for general-purpose audio output applications
- Surface mount construction utilizing pad terminations for circuit board integration
- Operates at a nominal impedance of 4 Ohms to match standard amplifier outputs
Applications
- General-purpose audio signal reproduction in consumer electronics
- Integration into devices requiring surface-mounted acoustic transducers
- Audio feedback systems in industrial control panels
Procurement Notes
Verify the specific datasheet version for the SP-4022 to confirm exact mechanical dimensions and soldering profile requirements. Ensure that the receiving equipment supports the 4 Ohm impedance load and can deliver the required 5.0/6.0 W power rating without distortion. Confirm that the pad termination style matches the target PCB layout design before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, surface-mount dynamic speaker is required for general audio tasks. The 4 Ohm impedance and 80 dB sensitivity make it suitable for standard voltage-driven applications. Consider the 350 Hz frequency response as a baseline for mid-range audio reproduction needs within compact electronic assemblies.
Part Context
The SP-4022 belongs to the SP Series of speakers from Soberton Inc., which focuses on dynamic transducer solutions. This model represents a standard general-purpose audio output device designed for reliable performance in various electronic products. It complements other components in the series by offering a balance of power handling and acoustic output.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints and electrical requirements if considering alternative suppliers.
