How to avoid the interference of mobile signals on sound?
In order to solve the noise caused by the interference of mobile phone signals, most people take the way of keeping their mobile phones away from the speakers, but this way is unrealistic, especially for consumers who use computer speakers, because many people need to use their mobile phones at any time at work. Therefore, here we suggest using shielding method to solve it. In fact, in the internal design of the speaker, there are more or less shielding functions in the aspects of plate structure, circuit board wiring, signal line layout, magnetic shielding treatment, etc., but the performance of different grades of speakers in shielding mobile phone signal interference is also very different. The audio amplifier inside the speaker can be shielded by copper wire, so as to reduce the gain value of the power amplifier circuit and reduce the interference of mobile phone signals.
The reasons why mobile signals interfere with sound:
In the course of life, almost everyone has encountered the problem of cell phone signal interference. The mobile phone is placed next to the speaker, and the speaker will make noise when there is an incoming call or a text message. Even if there is no text message sometimes, the speaker will make a sound inexplicably. This is actually caused by the working principle of the mobile phone itself: under normal circumstances, the mobile phone will send a small signal to keep in touch with the wireless network base station, and once an incoming call or text message comes, the mobile phone signal will be instantly enhanced to ensure the signal strength of the call. The audio amplifier in the speaker will amplify the pulse signal of the mobile phone again, so there will be noise in the speaker.
