Motherboard beep-code speaker

This pair of miniature speakers plugs directly into a 2.54 pitch 4-pin header on a desktop motherboard. They provide the audible POST codes that indicate hardware status during boot. The short 6 cm red and black leads keep internal cabling neat. Builders and technicians who need basic diagnostic audio will find them suitable.

2.54 pitch 4-pin header connection

The supplied connector matches the standard motherboard speaker header, so no adapters or soldering are required. Each unit arrives ready to install, letting you restore or add beep-code feedback in seconds. The two-piece pack gives a spare for a second system or a replacement if one fails.

Compact buzzer for POST diagnostics

The speaker produces the simple tones used for memory, graphics and CPU error codes during power-on self-test. It is not designed for music, voice or continuous alarm volumes. Systems that already have an onboard piezo or that rely solely on visual debug LEDs will not benefit from this addition.

Questions about this item

Will the 2.54mm pitch 4-pin female header need to be replaced after repeated plugging?

The connector is a standard 2.54mm pitch 4-pin female header designed for motherboard speaker pins; it is rated for typical insertion cycles and does not require scheduled replacement.

What limits continuous operation of the beep buzzer?

The buzzer is intended for brief POST beep codes and alarm signals, not for sustained audio output; prolonged activation can overheat the piezoelectric element.

How much heat or noise does the mini speaker produce when powered all day?

During normal beep-code use the speaker emits only short audible tones with negligible heat; continuous power is not a supported operating mode.
