OWS-3117TA-4

Speakers Overview

The OWS-3117TA-4 is a general-purpose electromagnetic speaker manufactured by Ole Wolff Electronics Inc. It features a 31mm diameter and a top port configuration. The unit has a nominal impedance of 4 Ohms and a rated power handling capacity of 2 Watts, with a maximum power rating of 2.5 Watts. The frequency response spans from 100 Hz to 20 kHz, while the self-resonant frequency is specified at 240 Hz. The device offers an efficiency of 100 dBA and has a maximum seated height of 16.80 mm.

Speakers Feature Summary

• Top port acoustic design for directional sound projection
• Electromagnetic transduction technology for audio reproduction
• High efficiency output capability relative to input power

Speakers Applications

• General purpose audio signal reproduction
• Low-frequency resonance applications requiring specific resonant characteristics
• Compact audio devices requiring top-port mounting configurations

Speakers Procurement Notes

Verify the exact physical dimensions and terminal connection types against the official datasheet before integration. Confirm that the operating environment does not exceed the maximum power rating of 2.5 Watts to prevent thermal damage. Ensure the mounting space accommodates the 16.80 mm maximum height and 31mm diameter constraints. Cross-reference the impedance specifications with the driving circuit requirements to ensure proper matching and performance stability.

Speakers Selection Notes

Select this component when a compact electromagnetic speaker with a top port is required for general audio tasks. The 4 Ohm impedance and 2 Watt rating suit low-power consumer electronics. Consider the 240 Hz self-resonant frequency if bass response or specific resonance behavior is critical. Verify compatibility with available mounting structures due to the specific form factor and port location.

Speakers Part Context

This model belongs to the Ole Wolff Electronics Inc speaker lineup, characterized by electromagnetic construction. It is designed as a standalone audio transducer element rather than a complete assembly. The product series typically includes variations in impedance and power handling, but this specific part number defines the unique combination of 4 Ohm impedance, 2 Watt rating, and top port geometry.

Speakers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires verifying identical electrical parameters (4 Ohm, 2W) and mechanical dimensions (31mm diameter, 16.80mm height). Top port orientation must be matched to maintain acoustic performance.
