SP-2040

Overview

The SP-2040 is a general-purpose dynamic micro speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a maximum power handling capacity of 1 watt, with some sources indicating up to 2 watts. The device operates within a frequency range of 650 Hz to 6 kHz, centered around a self-resonant frequency of 650 Hz. It delivers an efficiency of 86 dBA and utilizes a top port design for sound output. The component has a seated height of approximately 8.40 mm (0.331 inches) and employs magnetic technology for operation.

Feature Summary

• Top port rectangular design for directional sound projection
• General-purpose dynamic driver construction
• High acoustic efficiency rating

Applications

• Embedded audio systems
• Microcontroller peripheral audio output
• General purpose electronic devices requiring compact speakers

Procurement Notes

Verify the specific datasheet version from Soberton Inc. to confirm exact power ratings, as sources vary between 1W and 2W maximum power. Ensure the top port orientation aligns with the mechanical enclosure design. Confirm active status and availability through authorized distributors, noting that packaging details such as tray quantities may vary by supplier.

Selection Notes

Select this component for applications requiring a compact, low-profile speaker with moderate frequency response. The 8-ohm impedance matches standard amplifier outputs. Consider the 650 Hz lower frequency limit when designing for bass-heavy content, as it is not suitable for full-range audio reproduction. Verify mechanical clearance for the 8.40 mm height constraint.

Part Context

The SP-2040 belongs to the SP Micro Speaker series from Soberton Inc., designed for embedded and portable electronics. It serves as a cost-effective solution for basic audio notification or voice playback in space-constrained environments. The series typically offers various impedance and size options to suit different circuit requirements.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. When replacing, match the 8-ohm impedance, 650 Hz-6 kHz frequency range, and similar physical dimensions. Verify that alternative components support the required 1W power handling and top port configuration if directional output is critical.
