Portable electronic device with loudspeaker assembly
2012
A portable electronic device with a loudspeaker assembly comprises a first shell, a second shell, a circuit board, the loudspeaker assembly and an antenna assembly. The circuit board is clamped between the first shell and the second shell. The face, facing the circuit board, of the first shell is provided with two containing grooves in a spaced and protruding mode. A first through hole is formed in the bottom wall of each containing groove. Two second through holes are formed in the positions, adjacent to the containing grooves, of the first shell. The two sides of the first shell are provided with sound outlets respectively. The loudspeaker assembly comprises two loudspeakers. The loudspeakers corresponding to the sound outlets respectively are installed on one surface of the circuit board in a spaced mode and contained in the two containing grooves correspondingly. The containing grooves are communicated with the sound outlets to be used as front sound cavities of the loudspeakers. The circuit board is provided with third through holes aligned to the second through holes. The antenna assembly corresponding to the loudspeakers is installed on the other surface of the circuit board. The antenna assembly is provided with groove-shaped space. The first through holes, the second through holes, the third through holes, the groove-shaped space and the sound outlets are sequentially communicated to be used as rear sound cavities of the loudspeakers.
