[已解决]行空板不能播放语音合成的文件音频

我发现我今天在用行空板使用aip的时候不能播放语音合成的音频，以下是错误信息：
pydub.exceptions.CouldntDecodeError: Decoding failed. ffmpeg returned error code: 1
record.mp3: Invalid argument
求大佬们帮我解决一下问题

错误行：
with open("record.mp3","wb") as fp:
  ->fp.write(json.dumps(text).encode())

这样也会报错：
with open("record.mp3","wb") as fp:
  ->fp.write(text)
TypeError: a bytes-like object is required, not 'dict'

错误信息是无法对record.mp3文件进行解码，完整程序发出来看看。

from unihiker import *
from pinpong.board import *
from aip import AipSpeech
import json


audio = Audio()
cilent = AipSpeech("","","")
text = cilent.synthesis("你好", "zh", 1, {"vol": 5,"spd": 5,"pit": 3,"per": 0})
with open("record.mp3","wb") as fp:
    fp.write(str(text).decode())
audio.play("record.mp3")
Board().begin()
pin1 = Pin(Pin.D24,Pin.IN)
dht = DHT11(pin1)
gui = GUI()
t = gui.draw_text(text=dht.temp_c(),x=0,y=0,color="#0000FF")
while True:
    t.config(text=dht.humidity())

代码发错了，第11行fp.write(str(text).encode())改成fp.write(json.dumps(text).encode())
