Sound amplification asks for device and energy to boost volume, such as in powered loud speakers. Smartphones and portable music players let you play music stored in your device on active and powered speakers. However, a way simpler alternative is a passive speaker (preferably non-electric). These speakers are mostly portable and utilize qualities of matter, design, and shape to amplify a sound. Some of them offer a low amplification of 10-20 decibels, while some others can add up to 60 decibels.
