Main Types Of Speakers (2)

Speakers are divided into internal speakers and external speakers, with external speakers generally referring to speakers. The built-in speaker refers to the MP4 player having a built-in speaker, so that users can not only listen to the sound emitted by the MP4 player through the headphone jack, but also through the built-in speaker. The MP4 player with built-in speakers eliminates the need for an external speaker and avoids the inconvenience of wearing headphones for a long time.
