People search things like projector where does the sound come from because the sound setup is the most confusing part of home theater. Some assume the sound is built inside. Others think they need a speaker. The truth is simple. The source of sound depends on the projector model that you choose.
Projector sound can be internal or external. Many projectors have their own built in speakers. Most projectors also have output paths to external sound devices.
The most premium example inside the Boss collection is the Boss S7 4K Portable Projector. It has its own speaker system built inside. It also supports Bluetooth and WiFi which lets the user connect to external audio systems easily.
Why built in speakers exist in projectors
A built in speaker makes projection easy when someone is just trying to watch something quick without setup. For example a child playing cartoons in a bedroom. Or quick presentation audio in a small office.
The Boss S7 provides a speaker inside so the user can get a full media experience right away. They do not have to set up external hardware if they do not want to. They just power on the device and audio comes out from the projector housing.
Built in sound gives quick access and reduces frustration for new users. This has always been one of the top requested features inside entry home cinema setups.
Where exactly inside the projector is the sound system located
Most projectors hold speakers on the internal chassis near the rear airflow area. This is because the back of the projector is where port clusters usually sit. This also keeps speaker distance away from the optical path so heat and audio do not interfere.
In the Boss S7 unit the speaker system sits close to the internal board area and sound vents through shaped outlets in the shell. The audio output is directional. So the sound pushes outward instead of inside the housing.
Why Boss S7 produces better audio than many low end units
The Boss S7 uses a higher lumen output and advanced chipset. This is not directly audio related. But these features allow it to support higher bitrate video streaming from built in Android.
Higher bitrates mean more detailed audio source. So the quality of the sound signal itself is more stable.
Then the projector can output this audio through its internal speakers or through a Bluetooth connection. This is the reason users praise its clarity on small room use. BestBuy
External audio gives the biggest jump in quality
Even though a projector can produce sound inside its own body the best sound always comes from bigger speakers.
The Boss S7 output path lets you connect external speakers wirelessly or wired.
Bluetooth speakers are common.
Sound bars are common.
Full home theater speakers are common.
The projector audio signal will send sound data into the external speaker device and the sound will play through that device.
This is where most users get the complete cinema style feel. User often says adding bigger speakers feels like the picture finally meets the sound.
