SP-1605

Overview

The SP-1605 is a dynamic speaker unit designed for mobile phone applications. It features an 8 Ohm impedance and a top port configuration with a round shape. The component supports an input power of 0.5 to 0.8 watts, delivering a sound pressure level of 87 dB. Its frequency response is centered around 900 Hz with a tolerance of plus or minus 20%. Termination is achieved via wire connections.

Feature Summary

• Dynamic speaker unit construction
• Top port acoustic design
• Wire termination method

Applications

• Mobile phone audio output
• General purpose speaker systems
• Portable electronic devices

Procurement Notes

Verify the specific suffix variant (e.g., -5) against the required datasheet parameters, as specifications such as sound pressure level and frequency may differ between versions. Confirm wire termination compatibility with the target circuit board layout. Ensure the 8 Ohm impedance matches the amplifier output requirements. Check for RoHS compliance status in the official documentation before finalizing procurement.

Selection Notes

Select this component when a compact dynamic speaker with wire termination is required for mobile or portable electronics. The 8 Ohm impedance suits standard low-voltage audio amplifiers. Consider the top port design for acoustic coupling constraints. Verify that the 0.8W power handling meets the system's peak volume demands without distortion.

Part Context

This part belongs to Soberton Inc.'s SP series of dynamic speakers. The series includes variants like SP-1605-5, which share similar form factors but may have distinct electrical characteristics. These units are engineered for integration into space-constrained consumer electronics requiring reliable audio reproduction.

Replacement Considerations

Direct substitutes must match the 8 Ohm impedance, wire termination style, and physical dimensions. Variants within the SP-1605 family, such as SP-1605-5, may serve as alternatives if their specific SPL and frequency responses align with the design requirements.
