Built-in speaker: a configuration in which a speaker is placed inside a computer device.For example, the speaker is placed inside the display, and there are computers that place the speaker in the main case.Due to the dense electronic components inside the computer equipment, the built-in peaker is generally designed with electromagnetic shielding to prevent interference with other components in the computer.
Additional, because get the limitation of space inside computer, the volume of built-in speaker won't be very big, because this kind of speaker has diaphaneity of treble clear, medium not enough, bass inadequacy characteristic.The advantage of built-in speaker is that they take up no extra space, and there are no impedance matching problems between speakers and sound cards.
External hanging speakers: the volume of external hanging speaker is slightly bigger than built-in speaker, tone quality is better also.External speakers are usually attached to the sides of the monitor, resembling the ears of the monitor.Outside hang speakers with respect to appearance character, have a variety of shapes such as flat model, box, circle, art, but volume and weight are not quite big.
External hang speakers with respect to function, cent active sound box and have no source sound box two big kinds.The passive speaker is directly connected with the speaker output port of the sound card, which is characterized by simple connection, light weight and small output power.An active speaker has a power amplifier and is connected to the LINE OUT port of the sound card. It's characterized by a larger output power, more connections, and a certain weight.
