OWS-151540S-8

Speakers Overview

The OWS-151540S-8 is a rectangular micro speaker manufactured by Ole Wolff Electronics Inc. It features an 8-ohm impedance and a maximum power handling capacity of 800 mW. The device operates within a frequency range of 100 Hz to 20 kHz, with a self-resonant frequency of 800 Hz. It delivers a sound pressure level of 92 dB and utilizes top porting for acoustic output. The physical dimensions are 15.0 mm x 15.0 mm with a seated height of 4.00 mm.

Speakers Feature Summary

• Rectangular miniature form factor designed for space-constrained IoT applications
• Top ported acoustic design for directional sound projection
• General-purpose audio reproduction capability

Speakers Applications

• IoT devices
• Miniature electronic equipment
• General purpose audio output modules

Speakers Procurement Notes

Verify the specific suffix (e.g., -DG) against the required datasheet revision when ordering. Confirm that the 800 mW power rating aligns with the target application's drive requirements. Ensure the 4.00 mm height constraint fits the mechanical enclosure. Cross-reference the 92 dB SPL specification with acoustic testing needs.

Speakers Selection Notes

Select this component for applications requiring a compact rectangular speaker with top porting. The 8-ohm impedance suits standard low-voltage drivers. Consider the 100 Hz to 20 kHz frequency response for general voice or alert tones rather than high-fidelity music. Verify mechanical fitment due to the 4.00 mm maximum seated height.

Speakers Part Context
