Claim 11:
12. A massager, comprising:
a rigid housing, comprising:
a sucking part, defining a first sucking opening and a sucking axis;
a first side part;
a second side part, arranged symmetrically with the first side part along the sucking axis;
a receiving part, received in the first side part and defining a first receiving space communicated with the first sucking opening; and

a driving assembly, comprising:
a piston, movably received in the first receiving space, the piston defines a reciprocation axis substantially parallel with the sucking axis; and
a driving element, at least partially received in the second side part and connected with the piston, the driving element is configured to drive the piston to reciprocate in the first receiving space to periodically generate a negative pressure and a positive pressure at the first sucking opening;

wherein the sucking part defines a first through hole configured to communicate the first sucking opening with the first receiving space; and a center line of the first through hole is parallel to and spaced apart from the sucking axis.
