4511

Overview

The Visaton 4511 is an electromagnetic miniature speaker from the K 14.25 series, designed for compact audio applications. It features a plastic diaphragm and operates at a nominal impedance of 8 Ohms with a power rating of 1 W. The unit measures 25 mm in length, 14 mm in width, and 5.3 mm in depth, weighing 2.5 g. It delivers a sound pressure level of 72 dBA and has a resonant frequency of 950 Hz. Operating within a temperature range of -25 °C to +70 °C, it offers IP64 protection and utilizes solder pad termination for panel mounting.

Feature Summary

• Electromagnetic transducer design optimized for small enclosures
• IP64 rated enclosure providing dust and water resistance
• Flat profile construction suitable for space-constrained installations

Applications

• Miniature electronic devices requiring integrated audio output
• Compact alarm systems and signaling units
• Small consumer electronics with limited internal volume

Procurement Notes

Verify the specific impedance variant required, as the K 14.25 series includes both 4 Ohm and 8 Ohm options. Confirm that the solder pad termination style matches your PCB or wiring harness design. Ensure the operating environment stays within the specified -25 °C to +70 °C range to maintain performance integrity and prevent damage to the plastic diaphragm.

Selection Notes

Select this component when a low-profile, ruggedized speaker is needed for harsh environments due to its IP64 rating. Compare against other K 14.25 variants if higher sensitivity or different impedance matching is required. Consider the 1 W power handling limit for continuous operation scenarios and ensure the 950 Hz resonance does not interfere with the target frequency response requirements.

Part Context

This part belongs to the Visaton K 14.25 series of miniature speakers. These components are characterized by their oval shape and plastic diaphragm construction. The series is engineered for high-volume production in compact audio applications where size constraints are critical. The 4511 designation specifically identifies the 8 Ohm impedance version within this family.

Replacement Considerations

Direct substitutes include other Visaton K 14.25 series models with identical dimensions but differing impedances, such as the 4 Ohm variant. Cross-brand replacements must match the 25x14x5.3 mm form factor and 8 Ohm impedance to ensure mechanical and electrical compatibility without circuit modification.
