Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

As shown in fig. 1:

a double-loudspeaker symmetrical sound box comprises a sound box body, wherein the sound box body comprises a machine shell 1, a rear cover 2, a left loudspeaker 3, a right loudspeaker 4 and a circuit board 5, a mobile phone containing groove 11 is arranged in the middle of the front end of the machine shell 1, a first mounting area and a second mounting area are respectively arranged on two sides of the mobile phone containing groove 11, the left loudspeaker 3 is positioned in the first mounting area, a first dust-proof net 12 is further arranged on the end surface of the first mounting area, the right loudspeaker 4 is positioned in the second mounting area, a second dust-proof net 13 is further arranged on the end surface of the second mounting area, a plurality of grooves 111 are arranged on the bottom surface of the mobile phone containing groove 11, the inner side surface of the mobile phone containing groove 11 is an inclined surface, two insertion holes 112 are further formed in the inclined surface, two USB female seats 6 are further fixed on the back surface of the inclined surface, one end of each USB female seat 6 is fixed in the insertion hole, the effect that is equivalent to cell phone stand, and the roughness of the bottom surface that the bar groove 111 can improve cell-phone storage tank 11 prevents the cell-phone landing, and when the user need carry out the cell-phone and charge, usable USB connecting wire inserts the USB plug end of USB connecting wire in female seat 6 of USB, and the other end is connected with the interface that charges of cell-phone, realizes the cell-phone function of charging, brings splendid experience for the user and feels.
