Embodiment Construction

[0024] Hereinafter, preferred embodiments of a microspeaker with an air adsorbent according to the present invention will be described in detail with reference to the accompanying drawings. In the description, some reference numerals may be omitted for the readability of the drawings in the case where an equivalent structure or the same configuration in the drawings can be easily recognized.

[0025] figure 1 is a schematic cross-sectional view of a microspeaker 10 with an air adsorbent according to an embodiment of the present invention. The micro speaker 10 may include a speaker unit 100 , a cabinet 200 , and an air adsorbent that may be located in a resonance space R defined between the speaker unit 100 and the cabinet 200 . The speaker unit 100 is housed in the case 200 to protect the speaker unit 100 from external influences. The speaker unit 100 for receiving an electric signal and generating sound may include, for example, a diaphragm, a voice coil, and a magnet.

Abstract

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 the air adsorbent.

Description

technical field [0001] The present invention relates to a microspeaker used in small electronic devices, and more particularly, to a microspeaker having a cabinet applied thereto and having an air adsorbent capable of improving low-frequency sound quality. Background technique [0002] The speaker converts electrical energy into mechanical energy to produce sound according to Fleming's left hand rule using a voice coil existing in an air gap. Recently, with the widespread spread of small electronic devices such as smartphones that require small internal speakers, the demand for small and elongated microspeakers has gradually increased. [0003] Since microspeakers are limited in size, shape, location of sound emission holes, etc., structures for obtaining high sound quality in a limited space have been considered. In particular, the box-type micro speaker module has the advantage that the micro speaker is provided in a box case serving as a resonance space, the box case is ...
