What will interfere with high-power stereo?

The methods to interfere with high-power audio are as follows:

1, making phone calls, receiving short messages, answering phones, electromagnetic waves interfere with sound;

2. The sound close to high-power household appliances will also interfere with the sound;

3. Use the WiFi router to communicate a lot of data at close range. At this time, the sound will be broken;

4. Need a radio transmitter, whose electromagnetic energy will interfere with the audio amplification circuit of the stereo or the unshielded connection loop of the external speaker.

Sound sound refers to other sounds besides human language and music, including the sounds of natural environment, animals, machines and tools, and all kinds of sounds made by human actions.

The loudspeaker consists of electromagnet, coil and horn diaphragm. The speaker converts the current frequency into sound. According to the principle of physics, when an electric current passes through a coil to generate an electromagnetic field, the direction of the magnetic field is the right-hand rule. Suppose the speaker plays the key C, and its frequency is 256Hz, that is, it vibrates 256 times per second. The speaker outputs 256Hz alternating current, and the current changes 256 times per second, emitting a C-tone frequency. When the electric coil vibrates with the loudspeaker diaphragm, it pushes the surrounding air to vibrate and the loudspeaker produces sound.

Integrated Circuit In the early 1960s, the United States first introduced the integrated circuit, which is a new member of audio technology. In the early 1970s, integrated circuits were gradually recognized by the audio industry because of their high quality, low price, small size and many functions. So far, thick film audio integrated circuits and operational amplifier integrated circuits have been widely used in audio circuits.
