HEADPHONE AND ACOUSTIC CHARACTERISTIC ADJUSTMENT METHOD

摘要

[Problem] To enable acoustic characteristics to be further improved. [Solution] The provided headphone is equipped with: a driver unit having a diaphragm; a housing that houses the driver unit and forms a sealed front air chamber to the front of the driver unit where the diaphragm is disposed, said front air chamber being spatially blocked off from the outside except at a sound output opening part; and an acoustic tube that directly connects to a first air hole at one end and spatially connects a rear air chamber of the driver unit to the outside of the driver unit via a tube, said first air hole being formed in a frame of the driver unit, and said rear air chamber being formed between the frame and the diaphragm.
