I saw the SONY ECM-C10 clip microphone, but this is a recording microphone, I don't know if it can be used on portable speakers
What an expert! That's the problem, because the microphone's sensitivity is very high. The problem may be more than a whine. And what you say, the sound that comes out goes into the microphone again, so that the amplifier expands the incoming sound and may cause an echo or something like that. About the sensitivity of the recording microphone, want to say a bit, in the recording, three meters outside people speak softly can distinguish sound, I was using PC-K200 capacitor wheat test. As for the clip capacitor, wheat has not been used, it is not clear.Of course, the above is the result of logical analysis. The actual sensitivity is not as high as expected. As long as the capacitance of the wheat line is not too short, not the microphone directly to the speaker's horn, this whistling sound is not.As for the actual situation, there is no real experience, not clear. But still can try, personal feeling can use.I'm sorry to have failed to solve your problem.
First of all, make sure, as long as the microphone socket is the same can be used. Interfaces are generally generic 3.5mm.I also have a "new online" guide microphone, the use of the microphone was bought when the recording pen to send the clip microphone, the effect is good.First of all, whether electret microphone or ECM-C10, this dedicated condenser recording microphone, the interface is generally universal 3.5mm, so you can use.But since the microphone positioning is used in recording, loudspeakers are put fine timber to petty use. Use the tape recorder for the best.
Recording microphones, microphones, and speakers have the same interface as they can be used.Many speakers have mono channels and different interfaces to ordinary microphones. Some can be used and some are not available.Ordinary computer recordings, microphones, microphones are stereo, and some are not sound on loudspeakers, so it's better to try or use a microphone instead of a microphone.
