Since the first guide wall 143 extends along the outer circumference of the diaphragm 12 and the second guide wall 144 is opposite to the diaphragm 12, the flow of the bass gas generated by the vibration of the diaphragm 12 is limited by the first guide wall 143 and the second guide wall 144 and can only flow to the user through the first guide port 142, thereby enhancing the bass effect of the above-mentioned gas flow guide audio 10.
As shown in fig. 3, in a further detailed manner, the housing 11 is provided with a third flow guiding wall 145 connected to the first flow guiding wall 143 and the second flow guiding wall 144 and used for changing the flow direction of the bass airflow, a flow guiding space 146 communicated with the first guiding space 141 is formed between the third flow guiding wall 145 and the housing 11, the third flow guiding wall 145 is provided with a flow guiding opening 147, and the flow guiding opening 147 is oriented in the same direction as the through hole 112. Thus, the bass air flow generated by the vibration of the diaphragm 12 will pass through the first guide space 141, then the guide space 146, and finally flow out through the guide opening 147. Since the flow guide opening 147 is oriented in the same direction as the through hole 112, the bass air flow is guided to the sound emission direction of the horn, and therefore, the bass effect of the air flow guide sound 10 is enhanced.
In detail, as shown in fig. 4, the first guiding opening 142 is a plurality of first guiding holes 148 uniformly distributed on the first guiding wall 143. In this way, bass airflow will be directed towards the user through the evenly distributed first baffle holes 148, the first baffle structure 14 being directed towards the user in use.

Of course, as shown in fig. 6 to 10, the number of the shells 11 may be two, the two shells 11 have the same structure, the two shells 11 are respectively provided with a diaphragm 12 and a speaker assembly 13, the two shells 11 are connected into a whole through the first diversion structure 14, the two diaphragms 12 are oppositely disposed, and the first guide space 141 is formed between the two diaphragms 12. Thus, the bass airflow is concentrated to the first guide space 141 by the vibration of the two diaphragms 12 and flows to the user through the first guide port 142, thereby enhancing the bass effect of the airflow guide sound 10.
Of course, it is also possible that the inner cavities 111 of the two housings 11 are communicated, and the first flow guiding structure 14 is a partition wall 16 respectively connecting the two diaphragms 12 and separating the first guiding space 141 from the inner cavity 111. Thus, the cavities 111 of the two housings 11 are communicated with each other, so that the vibration sound cavities of the two horn assemblies 13 are communicated with each other, thereby enlarging the volumes of the vibration sound cavities and further enhancing the bass sound.
The present invention should be considered as limited only by the preferred embodiments and not by the specific details, since modifications, equivalents, and improvements made within the spirit and scope of the invention are intended to be included within the scope of the invention.
