COM-19102

Speakers Overview

The SparkFun COM-19102 is a large surface transducer designed to convert mechanical vibrations into sound. It features a round shape with a 50mm diameter and stands 31mm tall. The unit operates at an impedance of 4 Ohms and has a power handling capacity of 10W. Its frequency range spans from 58 Hz to 20 kHz, with a self-resonant frequency of 58Hz. The device provides an efficiency of 85 dB when tested at 10W/1m.

Speakers Feature Summary

• Converts various surfaces into audible speakers through vibration transmission
• Round design suitable for mounting on diverse material types
• High efficiency output relative to input power

Speakers Applications

• Interactive art installations requiring unconventional audio sources
• Educational demonstrations of sound wave propagation
• Custom DIY speaker projects using non-traditional enclosures

Speakers Procurement Notes

Verify the specific supplier listing for current availability as stock levels fluctuate. Confirm that the 4 Ohm impedance matches your amplifier or driver circuit requirements. Ensure the mounting method supports the physical weight and vibration forces generated during operation. Check regional shipping restrictions if applicable.

Speakers Selection Notes

Choose this component when standard enclosed speakers are unsuitable due to aesthetic or spatial constraints. It is ideal for projects where the vibrating surface itself acts as the radiating element. Consider the mass and rigidity of the target surface, as these factors significantly influence sound quality and volume output compared to free-air performance.

Speakers Part Context

This part belongs to SparkFun's collection of general-purpose audio components. Surface transducers differ from conventional loudspeakers by lacking a traditional cone and enclosure. They rely on direct contact with a resonant body to produce sound, offering unique sonic characteristics and form factor flexibility for creative electronics applications.

Speakers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should evaluate other surface transducers based on matching impedance (4 Ohms), frequency response (58 Hz - 20 kHz), and physical dimensions (50mm diameter) if this specific model is unavailable.
