Advantages of audio control board


1. The directivity is very good.

2, the sound attenuation is small. With traditional speakers, when you get too close, you will find the sound is loud, and when you are a little farther away, you will feel that the sound is much smaller.

3. The fidelity of the sound is high. Generally, the traditional horn is in the shape of a sound cone. When it vibrates and emits sound, it tends to concentrate the sound in the throat, compress it, and then spread it out. The sound people hear is the sound that has been compressed and deformed. .

4. The shape is ultra-thin and does not take up space. Due to the special structure of the flat-panel speakers, the formed speakers can be placed in any position, unlike traditional speakers, the effect of hearing is also very different due to the different placement positions.

Technical indicators


Its technical indicators mainly include six items: frequency response, signal-to-noise ratio, dynamic range, distortion, transient response, stereo separation, and stereo balance.

1. Frequency response: The so-called frequency response refers to the frequency range of the audio equipment and the relationship between the amplitude of the sound wave and the frequency.

2. Signal-to-noise ratio: The so-called signal-to-noise ratio refers to the ratio of the playback sound of the audio system to the new noise generated by the entire system. The noise mainly includes thermal noise, humming noise, mechanical noise and so on.

3. Dynamic range: Dynamic range refers to the logarithmic value of the ratio of the maximum undistorted output power of the audio system to the system noise output power when it is static, in decibels (dB).

4. Distortion: Distortion means that after the audio system replays the audio signal, some parts of the original audio signal (waveform, frequency, etc.) have changed.

5. Stereo balance: Stereo balance indicates the difference between the gain of the left and right channels in the stereo playback system. If the imbalance is too large, the sound image positioning of the reproduced stereo will be offset.
