The miniature sound source 4 includes a plurality of miniature sound source units (not shown). One side of the micro sound source units is attached to the other side of the pressure-resistant glass 2, namely the lower pressure-resistant glass 21, by adopting a principle of concentric sound field concentration, so that the low-frequency propagation stability can be ensured, and the influence range is wide.
