A speaker set (20) for an electronic product (100) includes a hollow shell
(60), and a loudspeaker (50) accommodated in the shell. The shell
includes at least a spacing plate (68) which divides an inner space of
the shell into a first resonance chamber (61a) and a second resonance
chamber (61b). The loudspeaker includes first tone holes (52)
communicating with the first resonance chamber and second tone holes (54)
communicating with the second resonance chamber. The second resonance
chamber communicates with the first resonance chamber via at least an
inverted hole (69) defined in the at least a spacing plate. The first
resonance chamber communicates with a surrounding environment so that
sound emitted from the first and second tone holes of the loudspeaker can
be transferred to the surrounding environment.
