# 蜂鸣器含义（Pixhawk系列）
[Pixhawk-series flight controllers](../flight_controller/pixhawk_series.md) use audible tones/tunes from a [buzzer](../getting_started/px4_basic_concepts.md#buzzer) and colours/sequences from a [LED](../getting_started/led_meanings.md) to indicate vehicle state and events (e.g. arming success and failure, low battery warnings).
下面列出一组标准蜂鸣器声音。
:::info
**Developers:** Tunes are defined in [/lib/tunes/tune_definition.desc](https://github.com/PX4/PX4-Autopilot/blob/main/src/lib/tunes/tune_definition.desc) and can be tested using the [tune-control](../modules/modules_system.md#tune-control) module.
You can search for tune use using the string `TUNE_ID_name`(e.g. \`TUNE_ID_PARACHUTE_RELEASE)
