Loudspeaker box

一种音箱

Abstract

The utility model provides a loudspeaker box, which comprises a box body and a loudspeaker, wherein a board body aslant arranged at the rear part of the loudspeaker and made from a material used to manufacture the loudspeaker is arranged in and fixedly connected with the box body. The board body, which is aslant arranged at the rear part of the loudspeaker, enables an audio signal emitted from the loudspeaker to be subject to refraction. According to the utility model, although the wavelength of the low-frequency sound signal is long and the distance between the board body and the loudspeaker is short, the aslant arranged board body refracts the low-frequency sound signal emitted from the loudspeaker, and the phase and the time of the low-frequency sound signal are both spaced out. Therefore the low-frequency sound signal emitted from the loudspeaker can not be counteracted too much, and the depletion is greatly reduced accordingly.
本实用新型提供了一种音箱,包括箱体和扬声器,在所述箱体内设有位于扬声器后部的倾斜布置的板体。所述板体与箱体固定连接。板体由制造音响所用的材料制成。扬声器的后部倾斜布置的板体使得扬声器发出的声频信号产生折射,这样,尽管低频声信号的波长长和该板体离扬声器的距离短,但由于扬声器发出的低频声信号被该倾斜放置的板体折射了,其相位和时间都被拉开。因此。扬声器发出的低频声信号将不会被抵消很多,从而其损耗将大大减少。
