Abstract

An electronic device includes a casing, a speaker enclosure and an actuating and sensing module. The casing has an opening. The speaker enclosure is disposed within the casing to enclose a speaker, in communication with the opening of the casing and divided into a first speaker compartment and a second speaker compartment by a partition plate disposed corresponding to the opening, so that the opening of the casing is in communication with the first speaker compartment and the second speaker compartment. The actuating and sensing module is disposed within the first speaker compartment. The speaker is disposed within the second speaker compartment. The actuating and sensing module comprises a fluid transportation device and a sensor. The fluid transportation device is driven to transport a fluid from outside the casing into the first speaker compartment through the opening of the casing to make the fluid sensed by the sensor.
