SP-4005S

Overview

The SP-4005S is an active general-purpose dynamic speaker manufactured by Soberton Inc. It features a round shape with a 40mm diameter and utilizes magnetic technology for sound reproduction. The component operates within a frequency range of 500 Hz to 20 kHz, with a self-resonant frequency of 500 Hz. It has an impedance of 8 Ohms and a rated power of 1 W. The efficiency is specified at 93 dBA when tested at 100mW/100mm. Termination is provided via spring type connections, and the port is located on the top.

Feature Summary

General purpose dynamic speaker design utilizing magnetic technology
Top-mounted port location for directional sound output
Spring-type termination method for connection

Applications

General audio signal indication
Low-power consumer electronic devices
Basic sound output in compact enclosures

Procurement Notes

Verify part number accuracy against official Soberton Inc. documentation before purchase. Confirm that the spring-type termination matches your assembly requirements. Ensure the 8 Ohm impedance and 1 W power rating align with your circuit design constraints. Check for any specific packaging or handling instructions provided by the supplier.

Selection Notes

Select this model when a small form factor 40mm speaker is required. Consider the 500 Hz lower frequency limit for applications not needing deep bass. The 93 dBA efficiency indicates good sensitivity for low-power operation. Verify compatibility with available mounting space and electrical interface constraints.

Part Context

This component belongs to the SP series of speakers from Soberton Inc., which includes variants like SP-4005-1 and SP-4005-3Y. These parts share similar physical dimensions but may differ in termination style or specific electrical characteristics. The SP-4005S specifically denotes the version with spring-type termination and defined 8 Ohm impedance.

Replacement Considerations

SP-4005-1 is a related variant from the same manufacturer family. Verify if the solder eyelet termination of the SP-4005-1 is compatible with your existing board layout, as it differs from the spring-type termination of the SP-4005S.
