Because the speaker microphone in this embodiment has the bass radiator 11, considering that the negative sound of the two speakers 7 can still push the bass radiator 11 to work after being cancelled, the two speakers 7 cannot be symmetrically arranged in the speaker cavity 13. Therefore, in this embodiment, the two speakers 7 are asymmetrically arranged by making the included angles between the central axes of the two speakers 7 and the horizontal line different. Specifically, a sectional view of the sound box cavity 13 is used for illustration, the two speakers 7 are respectively installed at the left and right sides of the sound box cavity 13, a first included angle is formed between the central axis of the speaker 7 located at the left side and the horizontal line, a second included angle is formed between the central axis of the speaker 7 located at the right side and the horizontal line, and the first included angle and the second included angle are different in value. Through the asymmetric arrangement of the two loudspeakers 7, the projections of the back surfaces of the two loudspeakers 7 on the right vertical surface have non-overlapping parts, so that the negative sounds of the two loudspeakers 7 cannot be completely cancelled, and the parts which are not cancelled can effectively push the bass radiator 11.

Simultaneously, have different inclination through making two loudspeaker 7 for the horizontal plane in this application and improve bass radiator 11's work efficiency, for other dislocation mode, reduced loudspeaker 7 vertically ascending occupation space in audio amplifier cavity 13, reduced audio amplifier cavity 13's volume, reduced manufacturing cost. According to the structure of the actual product, in order to make the bass radiator 11 work normally and stably, the bass radiator 11 is installed in the cavity 13 of the sound box and is located at a different side from the speaker 7.

This embodiment reaches and makes two loudspeaker 7 have the dislocation on inclination, reduces the purpose that the negative direction sound of loudspeaker 7 was offset in the audio amplifier cavity 13 to realized improving the work efficiency that 7 negative direction air currents of loudspeaker promoted bass radiation 11, promote the low frequency, reduce the distortion, the technological effect of the true sound of better reduction, and then solved 11 work efficiency low of bass radiation in the audio amplifier microphone among the correlation technique, the relatively poor problem of bass effect.
