Do Projectors Have Sound?

We live in a world where the use of projectors is no longer limited to boring business presentations.

The said forgiving electronic device has been now used to play video games, watch TV, movies, and listen to music.

Frankly, these are just a few typical uses. Projectors these days have become so advanced that we are using them for all kinds of educational and entertainment purposes.

Most basement projectors back in the day used to have no sound. The unavailability of sound limited the use to business projections only.

As the world moved ahead, advancement also got the projector industry under the spell.

We began connecting speakers and using these electronic devices for purposes we have never used before.

Projectors have a variety of uses these days. Yet commonly they are hired for watching movies, Roku, playing games, and projecting business presentations.

Business presentations rarely need sound, however, movies and games can never be fun without sound.

The old projectors used to lack the sound feature or they have to be connected to a speaker to produce sound.

Since now we have been watching movies and playing games on projectors mostly without any speakers, the question arises “do today’s projectors have sound?” Here’s the truth;

Do Projectors Have Sound?

Yes, but not all projectors have sounds. Only a few projectors built for the home theater have a powerful inbuilt sound system. Since these projectors are designed to play movies and broadcast games, they come with a sound feature.

On the other hand, the projectors that are specifically designed and engineered to display business presentations, spreadsheets, and other such stuff usually do not have the inbuilt sound feature. However, these projectors do allow you to connect speakers in the hour of need.

If you take a stroll in the market, you would find a few countable pieces that come with an inbuilt sound system. It may take a few more years to have all projectors with the inbuilt sound feature.

Why Do All Projectors Not Have Sound?

Projectors are not supposed to produce sound, they are meant to project a bigger brighter picture. An inbuilt sound system is a plus, therefore, only a few projectors have this feature. Whether the projectors have an inbuilt sound system or not, they support additional speakers. So, if not directly you can get the sound from the projector indirectly.

How to Get Sound from the Projector?

If the projector does not have an inbuilt sound system, you can connect the additional projector speaker and get the sound from the projector by following the below-mentioned step-by-step guide;

  • Switch off the devices – Turn off the projector and the speaker 
  • Spot the relevant ports – Find the HDMI port on the speaker and the projector HDMI
  • Connect the projector and the speaker – Plug in one end to the projector’s HDMI port and the other end to the speaker’s HDMI port
  • Turn on the devices – Plug in your projector and the speakers in a reliable power source
  • You are done – Select the appropriate input source and enjoy high-quality sound

This works for almost all projectors with HDMI ports. If the projector does not have an HDMI port, you have to get sound from the projector via an audio cable.

  • Switch off the devices – Turn off and unplug the projector and the speaker
  • Connect the audio cable to the devices- Plug one end of the audio cable into the speaker and the other end into the projector in the appropriate ports
  • Connect miniplug cable – Now take the miniplug cable and plug it into the AUX jack on both devices
  • Switch on the projector – Plugin the projector into a power source and turn on the projector by pressing the power button
  • Get the sound – Select an appropriate source on your projector and there you have your little theater
