The loudspeaker converts the current signal into sound signal only when the signal current acts on it, so it is realized through energy conversion.PA Loudspeaker refers to an electroacoustic transducer that converts current signals into sound signals. Therefore, the power of power amplifier and loudspeaker horn should be configured according to what standard.First, confirm the installation size range with the customer, know what size, and know what horn speakers to recommend.
Secondly, determine what products to install on (car speakers, subwoofers, toys, etc.). These require very different sound quality and volume of speakers
Third, determine the impedance and power of the power amplifier. After that, determine how to configure the power supply of the speakers, which is the focus of our article. If the power of the loudspeaker is much greater than that of the power amplifier board, the power amplifier board may be burnt. The power of the power amplifier is larger than that of the loudspeaker, and the control of the loudspeaker is good. It is easy to control, calm and comfortable, which is conducive to fully tapping the potential of speakers, and the sound sounds natural and comfortable. The disadvantage is that too much volume may burn the speaker, so you should be careful to control the volume.
If the power ratio of the power amplifier is less than the loudspeaker, a small horse will pull a large car. It's hard to push the speaker. The sound is small and weak, which makes people feel reluctant and uncomfortable. The quality of the loudspeaker will not be fully utilized, and the power amplifier is easy to burn.
