SP570308-1

Overview

The SP570308-1 is a dynamic micro speaker manufactured by DB Unlimited. It features an 8 Ohms impedance and a nominal power rating of 250 mW. The unit delivers a sound pressure level of 105 dBA at a distance of 10cm, with a resonant frequency of 330 Hz. Physically, the speaker measures 19.5 mm in height and utilizes flush mounting. It operates within a temperature range of -20°C to +70°C.

Feature Summary

• Flush mount rectangular design for space-constrained applications
• Dynamic speaker technology for audio output
• Low profile construction suitable for compact devices

Applications

• Consumer electronics requiring compact audio solutions
• Portable communication devices
• Embedded audio systems in small form factor hardware

Procurement Notes

Verify the specific datasheet version from DB Unlimited or authorized distributors to confirm current manufacturing status and exact electrical tolerances. Ensure that the operating environment remains within the specified -20°C to +70°C range to maintain performance integrity. Cross-reference the 8 Ohms impedance and 250 mW power rating with system amplifier capabilities to prevent damage or distortion during integration.

Selection Notes

Select this component when a low-profile, flush-mount dynamic speaker is required for compact enclosures. The 8 Ohms impedance and 250 mW rating suit low-power audio circuits. Consider the 105 dBA sensitivity and 330 Hz resonance for applications prioritizing mid-range clarity over deep bass reproduction in small spaces.
