SP570408-1

Overview

The SP570408-1 is a dynamic speaker manufactured by DB Unlimited, designed for flush mounting applications. It features an 8 Ohm impedance and a nominal power rating of 500 mW to 800 mW. The unit operates within a frequency range starting at 420 Hz, delivering a sound pressure level of 101 dBA. Physical dimensions include a height of 16.5 mm to 20.5 mm, with an operating temperature range spanning from -30°C to +60°C.

Feature Summary

• Dynamic transducer technology for audio output
• Flush mount installation style for integrated designs
• Round shape construction with paper cone material

Applications

• Consumer electronics requiring compact audio solutions
• Industrial control panels with limited space
• Medical equipment needing reliable flush-mounted speakers

Procurement Notes

Verify the specific datasheet version for exact power ratings, as sources indicate variations between 500 mW and 800 mW. Confirm physical height requirements against design constraints due to reported dimensions of 16.5 mm and 20.5 mm. Ensure compatibility with 8 Ohm circuits. Check RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement.

Selection Notes

Select this component when a round, flush-mount dynamic speaker is required. The 8 Ohm impedance suits standard low-voltage audio drivers. Consider the 420 Hz minimum frequency response for applications not requiring deep bass. Verify thermal limits against the intended environment, noting the -30°C to +60°C operational range specified in official documentation.

Part Context

DB Unlimited produces a wide array of speakers in various shapes and sizes. The SP series includes round, oval, and rectangular options. This model belongs to the dynamic speaker category, distinct from MEMS or piezoelectric alternatives. It is part of a broader portfolio offering different frequency ranges and power ratings for diverse audio needs.

Replacement Considerations

SP570408-2 is a related model with similar dimensions but different acoustic parameters, including a lower sound pressure level of 85 dBA and a higher self-resonant frequency of 400 Hz. Verify electrical and mechanical compatibility before substitution.
