70094

Overview

The MISCO 70094 is a general-purpose voice speaker with an 83 mm (3.3-inch) diameter, housed in a plastic enclosure. It features a high-power neodymium magnet and a treated cone for environmental resistance. The unit operates at an impedance of 8 Ohms with a rated power of 4 Watts and a maximum of 8 Watts. The frequency range spans from 500 Hz to 9 kHz, with a sensitivity of 84 dB measured at 2.83 V input at one meter.

Feature Summary

Integrated design combining a treated cone and high-power neodymium magnet within a protective plastic enclosure
Environmentally resistant construction suitable for demanding conditions
All-in-one product configuration eliminating the need for separate housing assembly

Applications

Voice range audio output in embedded systems
USB-powered audio devices requiring compact speakers
Industrial equipment needing environmentally resistant audio components

Procurement Notes

Verify the specific frequency response requirements against the 500 Hz to 9 kHz range before ordering. Confirm that the 8-ohm impedance matches the amplifier output capabilities. Ensure the physical dimensions of the 83 mm enclosure fit the designated space. Check if the USB-powered variant aligns with the system's power supply architecture.

Selection Notes

Select this model when a compact, environmentally resistant speaker is required for voice applications. The neodymium magnet provides high efficiency in a small form factor. Consider the 8-ohm impedance and 4-watt rating for compatibility with existing audio circuits. The plastic enclosure offers durability without significant weight increase.

Part Context

This component belongs to the MISCO OEM speaker series, designed for integration into various electronic devices. It represents a standard solution for voice-range audio reproduction where size and environmental resilience are critical factors. The part is built to order, indicating availability based on production schedules rather than immediate stock.
