SP-1813S

Overview

The SP-1813S is a dynamic electromagnetic speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a rated power handling capacity of 500 mW. The device operates within a frequency range of 200 Hz to 3.4 kHz, with a resonant frequency of 800 Hz. The physical construction includes a rectangular form factor with a top port location and spring-type termination for electrical connection.

Feature Summary

• Electromagnetic transducer design suitable for general audio output applications
• Rectangular housing configuration with top-port acoustic orientation
• Spring-type termination mechanism for simplified circuit integration

Applications

• Mobile phone audio output units
• General purpose electronic devices requiring compact speakers
• Embedded systems with limited space constraints

Procurement Notes

Verify the specific datasheet version from Soberton Inc. to confirm exact mechanical dimensions and tolerance levels. Ensure compatibility with spring-type termination methods during PCB assembly. Check RoHS compliance status if required for specific regional regulations. Confirm that the 500 mW rating aligns with the target application's power supply capabilities.

Selection Notes

Select this component when a rectangular form factor and top-port sound projection are required. The 8-ohm impedance matches standard low-voltage amplifier outputs. Consider the 200 Hz to 3.4 kHz frequency response limits for voice or limited-bandwidth audio needs rather than full-range music reproduction. Verify that the spring termination method fits the available board layout.

Part Context

This part belongs to the SP series of dynamic speakers designed primarily for mobile communication devices. The series typically includes various sizes and impedance options tailored for portable electronics. The SP-1813S specifically addresses the need for compact, cost-effective audio solutions in handheld devices where space is at a premium.

Replacement Considerations

Check for direct substitutes such as the SP-1813 variant if minor mechanical differences exist. Compare impedance and frequency response against other Soberton models like the SP-1810 to ensure functional equivalence. Verify that any replacement maintains the same spring-type termination and rectangular footprint.
