WSP-7704

Overview

The WSP-7704 is a general-purpose electromagnetic speaker manufactured by Soberton Inc. It features a square shape with a top port location and an IP65 ingress protection rating, ensuring dust-tight and waterproof performance on the face. The unit has an AC impedance of 4 ohms at 1000Hz and a resonant frequency of 330Hz. Rated input power is 3.0 watts, with a maximum input power of 4.0 watts. The sound pressure level is specified at 102 dB. Physical dimensions include a length of 77.2mm and a height of 21mm.

Feature Summary

• IP65 rated waterproof and dust-tight construction for reliable operation in harsh environments
• Top port design integrated into a square frame structure
• Electromagnetic transducer technology for general audio output applications

Applications

• Industrial equipment requiring water-resistant audio signaling
• Outdoor electronic devices needing dust protection
• General purpose audio output in consumer electronics

Procurement Notes

Verify the specific datasheet edition (A/2017) when sourcing to ensure compatibility with current manufacturing standards. Confirm that the 4-ohm impedance matches the amplifier output requirements of the target system. Check physical mounting constraints against the 77.2mm length and 21mm height specifications to ensure proper enclosure fitment before finalizing procurement orders.

Selection Notes

Select this component when a ruggedized speaker solution is required for environments where moisture or dust exposure is likely. The 3-watt rated power provides sufficient volume for general announcements or alerts without excessive energy consumption. Ensure the application can accommodate the 4-ohm load and that the top-port orientation aligns with the acoustic design of the host device.

Part Context

This model belongs to the WSP series of waterproof speakers from Soberton Inc., designed specifically for durability. The series emphasizes environmental sealing alongside standard acoustic performance metrics. This particular variant utilizes a rectangular frame geometry distinct from other circular designs in the manufacturer's lineup.

Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement. Verify mechanical footprint and electrical impedance compatibility if considering alternative manufacturers.
