How to deal with the projector without its own sound?

Projector is a commonly used imaging device, which can project the contents of computers, mobile phones and other devices onto a big screen through an optical lens, so that the audience can see the picture more clearly. But some projectors don't have their own sound. What should we do at this time? Here are some possible solutions.

1. External speakers: The easiest way is to add sound to the projector through external speakers. Just plug the audio cable of the speaker into the audio output port of the projector. This method is suitable for using projectors in a small area, such as watching movies or playing courseware at home.

2. External power amplifier: If you need to use the projector in a large range, such as meeting rooms, lecture halls and other places, it is recommended to use an external power amplifier. The external power amplifier can amplify the audio signal output by the projector and play it through the sound box or speaker, making the sound clearer and more realistic.

3. Connect directly to the TV or stereo: If you have a TV or stereo at home, you can also connect the projector directly to these devices, so that you can not only get better sound effects, but also enjoy greater screen effects. Just plug the audio cable output by the projector into the audio input port of the TV or stereo.

4. Use headphones: If you need to use the projector in a quiet environment, such as watching movies in the library at night, you can use headphones to listen to the sound. Just plug headphones into the audio output port of the projector, and you can get more private and clear sound effects.

In a word, it's not a problem that the projector doesn't have its own sound. Just choose a suitable scheme to add sound. The specific method can be selected according to factors such as site, equipment and budget. Only the perfect combination of sound and painting can get better audio-visual enjoyment.
