LOUDSPEAKER AND AUDIO PLAYBACK DEVICE HAVING SAME

WIPO Patent Application WO/2014/059837

A1

The present invention provides a loudspeaker which can be arranged in a loudspeaker box and generate sound waves. The loudspeaker comprises at least two basin rack structures which are mutually coaxial and connected in a parallel mode, and each basin rack structure has a basin rack and a paper cone which is pasted to the basin rack and used for generating the sound waves. Each basin rack is in a cylindrical shape, a gap used for transmitting the sound waves out from the corresponding basin rack is formed on the sidewall of the basin rack, and the orientation directions of the gaps on two adjacent basin racks are opposite. According to the loudspeaker of the present invention, multiple basin rack structures are connected in the parallel mode, the gap used for transmitting the sound is formed on the basin rack of each basin rack structure by employing a pedestal and a baffle plate, and the orientation directions of the gaps on the two adjacent basin rack structures are opposite, so that the phase difference between the sound waves generated by the paper cones of the two adjacent basin rack structures is 180 degrees. Thus, interference occurs to enhance the sound transmission effect when two sound waves are overlapped, and the acoustic short circuit phenomenon can be improved.
