如何使用Pyqt5 QtMultimedia播放声音？

pip install PyQt5

from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton
from PyQt5.QtMultimedia import QSoundEffect
import sys

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("Sound Player")
        self.setGeometry(100, 100, 300, 200)

        self.button = QPushButton("Play Sound", self)
        self.button.setGeometry(100, 80, 100, 30)
        self.button.clicked.connect(self.play_sound)

        self.sound_effect = QSoundEffect(self)
        self.sound_effect.setSource(QUrl.fromLocalFile("path/to/sound/file.wav"))

    def play_sound(self):
        self.sound_effect.play()

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())
