SP-1511L

Overview

The SP-1511L is a general-purpose dynamic speaker manufactured by Soberton Inc., designed for mobile telephone applications. It features an 8 Ohm impedance and a frequency range of 300 Hz to 5 kHz. The unit has a rated power of 700 mW and a maximum short-term power of 1.0 W. Efficiency is specified at 83 dBA SPL, measured at 10 cm with a baffle. The physical dimensions are rectangular, measuring 15.00 mm in length and 11.00 mm in width, with a maximum seated height of 3.00 mm. Termination is provided via wire leads.

Feature Summary

• Rectangular top-port design suitable for compact mobile device integration
• Utilizes magnetic technology for dynamic sound reproduction
• Wire lead termination for straightforward circuit connection

Applications

• Mobile telephone audio output
• General purpose electronic devices requiring small form factor speakers
• Portable consumer electronics

Procurement Notes

Verify the specific suffix (e.g., L, L-1, L-2) as these denote variations in power handling, frequency response, or termination type. Confirm mechanical fit against the 15.00mm x 11.00mm footprint and 3.00mm height limit. Ensure the 8 Ohm impedance matches the amplifier output requirements. Request the official datasheet for the exact variant to confirm electrical tolerances and acoustic performance metrics before finalizing procurement.

Selection Notes

Select this component when a low-profile rectangular speaker is required for mobile applications. The 8 Ohm impedance is standard for many portable audio circuits. Consider the 300 Hz to 5 kHz frequency range for voice-centric or limited-bandwidth audio needs. Compare variants like SP-1511L-1 or SP-1511L-2 if different power ratings or extended frequency responses are necessary. Ensure the wire lead termination style fits the assembly process.

Part Context

The SP-1511L belongs to Soberton's SP series of micro speakers. This series focuses on compact, high-efficiency units for handheld devices. The model shares the same physical envelope as other SP-1511 variants but differs in electrical specifications such as power handling and frequency response based on the suffix. It represents a standard solution for cost-sensitive mobile audio modules.

Replacement Considerations

Direct substitutes include SP-1511L-1 and SP-1511L-2 from Soberton, which share similar dimensions but differ in power and frequency specs. Cross-manufacturer replacements must match the 15x11mm footprint, 8 Ohm impedance, and wire lead termination. Verify that alternative models support the required 300Hz-5kHz bandwidth and 83dBA efficiency level.
