What is loudspeaker?
Loudspeaker is a small sound output device fitted into a mobile phone, or other communication device, which is used to produce sound. Smartphone audio depth and clarity are limited by small-sized speakers. Low-power amplifiers produce tinny or hollow sound, while many techniques that compress files to make them easy to store and stream also compromise the audio quality.
Loudspeakers are also used to take calls on hand-free mode or conference calls by reproducing voice calls out loud. If it is used for fun, conference calls or just for plain ringing, there is one single thing that’s important and that’s loudness.
