SP-4510

Overview

The SP-4510 is a general-purpose dynamic speaker unit manufactured by Soberton Inc. It features a round shape with a top port location and solder pad or eyelet termination options. The component operates within a frequency range of 700 Hz to 6 kHz, with a self-resonant frequency of 700 Hz. It has an impedance of 16 Ohms and an efficiency of 82 dBA. The maximum input power is rated at 300 mW (0.3 W), with a peak handling capacity of 3.0 W. The seated height is approximately 10.00 mm.

Feature Summary

• General purpose dynamic speaker design suitable for standard audio applications
• Top port location for directed sound output
• Round physical form factor with magnetic technology

Applications

• Consumer electronics requiring compact audio output
• Industrial control panels with status indication needs
• Embedded systems with limited space constraints

Procurement Notes

Verify the specific suffix variant (e.g., SP-4510-1) against your schematic requirements, as termination types such as solder pads or eyelets may differ between sub-models. Confirm that the 16 Ohm impedance matches your amplifier output stage to ensure proper power transfer and prevent damage. Check RoHS compliance documentation if environmental regulations apply to your manufacturing process. Ensure the 300 mW continuous power rating aligns with your system's operational duty cycle.

Selection Notes

Select this component when a small, round speaker with top-porting is required for general audio signaling. The 16 Ohm impedance is standard for many low-power audio circuits. Consider the 82 dBA efficiency for volume requirements in enclosed spaces. Verify mechanical dimensions, specifically the 10.00 mm height, to ensure fit within the enclosure. Compare against other Soberton SP series units if different frequencies or impedances are needed.

Part Context

The SP-4510 belongs to Soberton Inc.'s SP Dynamic Speaker Unit series. This line includes various models differentiated by impedance, frequency response, and termination style. The SP-4510-1 is a common variant featuring 16 Ohm impedance and eyelet terminations. These speakers are designed for cost-effective integration into mass-produced electronic devices requiring reliable acoustic performance.

Replacement Considerations

Direct substitutes include other Soberton SP series speakers with matching 16 Ohm impedance and similar frequency ranges. Verify mechanical compatibility, particularly the mounting hole pattern and overall diameter. Ensure the replacement unit supports the same power handling capabilities to maintain system reliability.
