SPK-I-81368

Overview

The SPK-I-81368 is a rectangular bone conduction transducer manufactured by ISL Products International. It operates with a nominal impedance of 4 Ohms and handles a power rating of 3 Watts. The device features a frequency range spanning from 800 Hz to 2 kHz and delivers a sound pressure level of 95 dB. Unlike conventional speakers, this component utilizes magnetic voice coil pulses to generate vibrations without a moving cone. It is supplied in bag packaging and maintains an active product status.

Feature Summary

• Bone conduction technology eliminates the need for a traditional moving cone structure
• Rectangular form factor designed for specific mounting configurations
• Magnetic drive mechanism generates vibration through voice coil current pulses

Applications

• Audio devices requiring direct skeletal transmission
• Hearing assistance equipment utilizing bone conduction principles
• Specialized communication headsets

Procurement Notes

Verify the exact part number SPK-I-81368 against official ISL Products International documentation before procurement. Confirm that the 4 Ohm impedance and 3W power rating match your circuit requirements. Ensure compatibility with the specified 800 Hz to 2 kHz frequency response for your application. Check for any specific handling instructions related to the rectangular transducer design.

Selection Notes

Select this component when bone conduction audio transmission is required rather than air-conducted sound. The 4 Ohm impedance suits low-voltage driver circuits. The 3W power handling capability defines the maximum input signal limits. The rectangular shape influences mechanical integration and available surface area for attachment to the target medium.

Part Context

This transducer belongs to the category of magnetic bone conduction speakers. It differs from standard dynamic drivers by transmitting sound via physical vibration rather than air pressure waves. The rectangular package distinguishes it from circular counterparts. It serves niche applications where direct bone coupling is necessary for audio delivery.

Replacement Considerations

No publicly confirmed substitute part numbers are available for this specific model. Replacement requires matching the 4 Ohm impedance, 3W power rating, and rectangular form factor. Verify that alternative components support the same bone conduction technology and 800 Hz to 2 kHz frequency range.
