In the related art, negative sounds in the sound cavity are mutually offset by the loudspeakers in the sound box microphone in a symmetrical arrangement mode, and the arrangement mode can play a role in vibration elimination. However, when a bass radiator is installed in a sound box microphone for obtaining a better bass effect, because the negative sounds are mutually counteracted by symmetrically arranged loudspeakers, the air flow in the sound cavity is slowed down, so that the bass radiator cannot work efficiently, and the bass effect is reduced.

To solve the above technical problem, as shown in fig. 1, an embodiment of the present application provides a speaker microphone, including: a sound box cavity 13, a loudspeaker 7 and a bass radiator 11; wherein,

the two loudspeakers 7 are oppositely arranged in the sound box cavity 13, and the included angles between the central axes of the two loudspeakers 7 and the horizontal line are different, so that the two loudspeakers 7 are arranged in an asymmetric manner;

the bass radiators 11 are arranged in two opposite positions in the sound box cavity 13, and the two bass radiators 11 and the loudspeaker 7 are positioned on different sides.

In this embodiment, the sound box cavity 13 is a hollow structure, which may be a regular polygon structure or a special-shaped structure. Loudspeaker 7 and bass radiator 11 are all installed in audio amplifier cavity 13, and the sound production end of loudspeaker 7 is towards the outside of audio amplifier cavity 13. Still need consider when using this audio amplifier microphone and slowing down the problem of audio amplifier cavity 13 vibration, consequently this embodiment loudspeaker 7 sets up to two of relative setting, and the negative-going sound that two loudspeaker 7 produced in audio amplifier cavity 13 can offset partly each other to the vibration that slows down audio amplifier cavity 13 and produce because of negative-going sound.

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 have different values. 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. In order to enable the bass radiator 11 to work normally and stably according to the structure of the actual product, the bass radiator 11 is installed in the cabinet cavity 13 and located at a different side from the horn 7 in the present embodiment.

Furthermore, since no additional electronic devices are required to be installed on the ring side of the cavity 13 of the sound box in this embodiment, after the two speakers 7 are installed, the two sides still have installation spaces. Therefore, to further enhance the bass effect of the product, the bass radiators 11 are arranged in two and oppositely arranged at the other two sides of the cavity 13 of the sound box. For example, two speakers 7 are installed on the left and right sides of the cabinet cavity 13, and two bass radiators 11 are installed on the front and rear sides of the cabinet cavity 13.

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.

As shown in fig. 1, the installation of the horn 7 is limited by the structure of the cavity 13, and in order to enable the horn 7 to be normally and stably installed on the cavity 13 and reduce the structural change of the cavity 13, the inclination angle of the horn 7 is not too large, so that the included angle between the central axis of the horn 7 and the horizontal line is 0-20 ° in this embodiment. For example, the central axis of the right horn 7 is parallel to the horizontal, and the central axis of the left horn 7 is at an angle of 0-20 °, which may be 10 °,15 °, 18 °, or 20 °. It will be appreciated that alternatively the central axis of the left horn 7 may be angled at 5 ° to the horizontal and the central axis of the right horn 7 may be angled at 15 ° to the horizontal.
