如果文件是.wav，则只需使用qsound：

import os
import sys

from PyQt5 import QtCore, QtMultimedia

CURRENT_DIR = os.path.dirname(os.path.realpath(__file__))

def main():
    filename = os.path.join(CURRENT_DIR, "beal.wav")

    app = QtCore.QCoreApplication(sys.argv)

    QtMultimedia.QSound.play(filename)

    # end in 5 seconds:
    QtCore.QTimer.singleShot(5 * 1000, app.quit)

    sys.exit(app.exec_())

if __name__ == "__main__":
    main()

如果要播放更多格式，则应使用qmediaplayer：

import os
import sys

from PyQt5 import QtCore, QtMultimedia

CURRENT_DIR = os.path.dirname(os.path.realpath(__file__))

def main():
    filename = os.path.join(CURRENT_DIR, "sound.mp3")

    app = QtCore.QCoreApplication(sys.argv)

    player = QtMultimedia.QMediaPlayer()

    def handle_state_changed(state):
        if state == QtMultimedia.QMediaPlayer.PlayingState:
            print("started")
        elif state == QtMultimedia.QMediaPlayer.StoppedState:
            print("finished")
            QtCore.QCoreApplication.quit()

    player.stateChanged.connect(handle_state_changed)

    url = QtCore.QUrl.fromLocalFile(filename)
    player.setMedia(QtMultimedia.QMediaContent(url))
    player.play()

    sys.exit(app.exec_())

if __name__ == "__main__":
    main()
