The present invention relates to a micro-speaker for use in a small electronic device, and more particularly, to a micro-speaker having an enclosure applied thereto and having an air adsorbent which can improve the low frequency sound quality. According to the present invention, it is possible to provide a micro-speaker which shows excellent improvement in the low frequency characteristics, regardless of a mass ratio of silicon to aluminum of an air adsorbent, and also possible to provide a micro-speaker which shows excellent improvement in the low frequency characteristics at a low cost, by reducing a mass ratio of silicon to aluminum, as compared with the conventional micro-speaker having an air adsorbent.

Micro-speaker having an air adsorbent

The present invention aims to provide a microspeaker with enhanced low frequency characteristics, by arranging an adsorbent for adsorbing the air in a resonance space and defining a virtual back volume by the air adsorption of the adsorbent. According to an aspect of the present invention, there is provided a microspeaker enclosure with an air adsorbent, including a microspeaker, an enclosure with the microspeaker provided therein, the enclosure defining a resonance space, and an air adsorbent applied to the resonance space of the enclosure, wherein an air adsorption mole ratio per unit volume of the air adsorbent based on a change in the unit pressure is 40.6 mol/m&#xb7;atm.
