Using the 3" Sound Focusing Tube
Getting the most out of the speaker:
Without going into too much (boring) detail,
a bit of technical info should be helpful. Speakers create sound by rapidly moving their speaker cone which moves / vibrates the air in front of them (or behind), creating the sound that we hear. Inside the speaker is a small coil of wire attached to the base of the cone and positioned inside a magnet. Electricity produced by the sound module running through the coil causes this coil to vibrate which vibrates the speaker cone. Viola - sound! However… there’s a catch… Speakers have a front side… and a back. When the speaker cone is rapidly moving in and out to produce sound out of the front, it is also doing the same thing out the back side. Unfortunately, when one side is pushing air the other side is “pulling” air. This effect on the air surrounding the speaker has a self-cancelling effect known as being “out-of-phase”. Simply put: “Nature abhors a vacuum”. The air pulling effect tries to “reach around” the speaker and grab the air being pushed on the front side. The result is greatly reduced sound output from the speaker.
