2948

Overview

The Visaton 2948 is an electromagnetic mini speaker with a diameter of 22 mm and a depth of 8.5 mm. It features an impedance of 8 Ohms and a power rating of 500 mW. The unit has a frequency response starting at 530 Hz and a sound pressure level of 74 dBA. It utilizes solder lug termination and supports panel mounting. The operating temperature range spans from -20 C to +65 C, and it carries an IP64 rating for dust and water resistance.

Feature Summary

• Compact round design suitable for space-constrained installations
• Integrated four-hole mounting pattern for secure panel attachment
• Robust construction with IP64 ingress protection rating

Applications

• Miniature audio output devices
• Portable electronic equipment speakers
• Industrial control panel indicators

Procurement Notes

Verify the specific impedance variant required, as the model number may correspond to different resistance values in some catalogs. Confirm that the solder lug termination style matches the target circuit board or wiring harness interface. Ensure the enclosure design accommodates the 22 mm diameter and 8.5 mm depth dimensions while maintaining the necessary acoustic clearance for proper sound projection.

Selection Notes

Select this component when a small form factor is critical alongside moderate acoustic output requirements. The 8 Ohm impedance aligns with standard low-power amplifier outputs. Consider the IP64 rating if the application involves exposure to dust or occasional water splashes. The wide operating temperature range ensures reliability in varied environmental conditions without requiring additional thermal management.

Part Context

This part belongs to the Visaton K 23 SQ series of miniature speakers. The series is characterized by compact dimensions and robust electromagnetic transducer designs intended for general-purpose audio applications. The 2948 designation specifically identifies the 8 Ohm impedance variant within this product line, distinguishing it from other resistance options available in the same physical package.

Replacement Considerations

Check for Visaton parts sharing the K 23 SQ series designation but with different impedance ratings if electrical matching allows. Verify dimensional compatibility with existing mounting holes before substituting with non-Visaton brands.
