Hello, there are several possibilities: 1. It may be that when the sound is turned on, the sound membrane voice coil in the speaker vibrates greater, which can just hit a foreign object somewhere inside, resulting in a squeaky noise. When the sound is on, the amplitude of the voice coil of the voice membrane is small, and the sound is normal if the foreign body cannot be touched.

2. The parameters and specifications of the speaker are incorrect. Did you go outside in the middle of the time to fix the speakers? Either the speaker parameters are wrong, or the noise of the portable shrine speaker is bad (it is also bad to open a loud sound and have noise).

3. Internal interference, the mobile phone seems to have a detection signal after a period of time, put the mobile phone on the side of the speaker, sometimes it will ring a few times, but your mobile phone may interfere with your own speaker. 4. When the mobile phone is turned on and used, the internal circuit of the machine is working, and there will be a slight sail alternating current sound. I hope my answer is helpful to you, and I wish you good health and a happy mood!
