Problems solved by technology

[0019] In such a thin speaker, the mutual magnetic induction between the voice coil and the magnetic object is weak, so it is difficult to generate high-quality sound pressure
Therefore, the efficiency of the loudspeaker is compromised
[0020] Especially, when in small devices, such as mobile terminals, the above-mentioned speaker with the voice coil printed on the diaphragm is adopted, because the diameter of the speaker is about 15 mm, the efficiency of the speaker is low, and high performance cannot be obtained. quality reproduced sound

Abstract

The present invention provided a speaker for mobile terminal capable of realizing high sound quality after establishing wide frequency characteristics and good high frequency distortion characteristics.

Description

technical field [0001] The present invention generally relates to a speaker for a mobile terminal and a manufacturing method thereof, and more particularly to a speaker for a mobile terminal having a thin structure and having wide-band characteristics and good high-frequency distortion characteristics, thereby obtaining good sound quality, and the speaker Manufacturing method. Background technique [0002] Recently, as multimedia functions are rapidly provided to terminals of mobile telecommunication, good sound quality has become available. Further, as the thickness of products continues to decrease, space-efficient designs with thin housings are more attractive. [0003] As the size of liquid crystal display (LCD) windows grows, the space available to accommodate speakers that serve as sound outlets decreases. Therefore, it is required to develop a new loudspeaker that has good sound quality and has a slim structure. [0004] In general, a loudspeaker is a sound-generat...
