Product Description
This motherboard internal speaker is a compact, high-performance component designed for desktop computers. It consists of three key parts:

Buzzer Module: Injection-molded plastic housing (protects the internal speaker unit for consistent sound).
2-Pin Connector: Labeled "SPEAKER" for easy identification, compatible with all standard motherboard headers.
6.5cm Cable: Flexible, insulated wires (red/black) for secure connection and placement in PC cases.

It's engineered to provide reliable BIOS post beep codes, helping users quickly diagnose hardware problems (e.g., unrecognized RAM, faulty GPU) during system startup. The plug-and-play design makes it suitable for both novice builders and professional technicians.

Important Notes
No Polarity Restriction: The 2-pin plug works regardless of orientation—no need to worry about reversed connections.

Avoid Physical Damage: Do not squeeze the buzzer or cable between case hardware (e.g., graphics cards, hard drives) during installation to prevent sound failure. Reference BIOS Beep Codes: Beep patterns (e.g., 1 long + 2 short) vary by motherboard brand—check your motherboard manual for error interpretations.
Correct Interface Only: Connect exclusively to the motherboard's "SPEAKER" header; do not plug into power/fan ports to avoid hardware damage.
