PIEZOELECTRIC MICRO BLOWER

摘要

A piezoelectric micro blower includes a blower body that includes a first wall and a second wall. An opening is provided at a portion of the first wall that faces an area of the approximate center of a driver of the piezoelectric micro blower. An opening is provided at a portion of the second wall. A central space that is in communication with the openings is provided between the first and second walls. Inlet passages through which the central space is in communication with the outside are provided between the first and second walls. Bottleneck portions are provided at regions at which the inlet passages are connected to the central space. The driver vibrates when a voltage is applied to a piezoelectric element. The first wall vibrates in a corresponding manner as the driver vibrates.
