Projectors basically have their own speakers, but the power of the speakers may be different. The sound quality of most projectors is not as good as that of professional audio equipment, and can only play sound. Therefore, if you pursue sound quality effects, It is recommended to use an external speaker.

Of course, there are also a small number of projectors with built-in high-quality audio, and also support the Bluetooth audio function, which can be connected to a mobile phone to play music from the mobile phone.

At the beginning, the projector was just an image terminal in audio-visual equipment, but with the continuous development of science and technology, more and more functions were added, and accessories such as built-in intelligent system and high-quality audio were added. The higher the price of a projector, the better the picture and the better the built-in speaker. If you feel that the projector’s audio can not meet your needs, you can connect an external audio or power amplifier device through HDMI cable, audio cable or Bluetooth function.
