SP-4018

Overview

The SP-4018 is a general-purpose dynamic speaker manufactured by Soberton Inc. It features an 8 Ohm impedance and a rated power of 2 W, with a maximum power handling capacity of 2.5 W. The device delivers a sound pressure level (SPL) of 84 dB and operates within a frequency range of 3 kHz to 5 kHz, with a self-resonant frequency of 350 Hz. Designed for top porting, the speaker utilizes a magnetic technology and includes a round shape configuration.

Feature Summary

• General-purpose dynamic speaker design suitable for broad audio applications
• Top ported acoustic output configuration for directional sound projection
• Magnetic transducer technology utilizing neodymium or similar magnet materials

Applications

• Consumer electronic audio devices requiring compact sound output
• Industrial control panels needing audible status indicators
• General purpose intercom or communication systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required termination styles and mounting configurations. Confirm that the 8 Ohm impedance aligns with the target amplifier output specifications to prevent mismatch issues. Check for any recent revisions in the mechanical dimensions to ensure proper fit within the intended enclosure space.

Selection Notes

Select this component when a standard 8 Ohm impedance and 2 W power rating are required for general audio tasks. Consider the 84 dB SPL efficiency for applications needing moderate volume levels without excessive power consumption. Evaluate the physical dimensions and top-port orientation to ensure integration into the final product housing allows for unobstructed sound propagation.

Part Context

The SP-4018 belongs to Soberton Inc.'s lineup of electromagnetic switching components and sound devices. This series includes various dynamic speakers, piezo buzzers, and microphones designed for industrial and consumer electronics. The part represents a standard solution for basic audio reproduction needs within compact form factors.

Replacement Considerations

Direct substitutes may include other 8 Ohm, 2 W general-purpose speakers from Soberton such as the SP-4018-S variant if different packaging is needed. Cross-reference with other manufacturers' equivalent ratings, ensuring impedance, power handling, and dimensional constraints match the original design requirements.
