Abstract
The present invention relates to a downhole tool () to be submerged into a well fluid from a top of a well, comprising a first tool section (), a tool housing () having an inner face (), a downhole communication module () for communicating through a well fluid in a downhole well to operate the downhole tool, comprising a piezoelectric transceiver () having a first face () and a second face () and being arranged in the tool housing, wherein an element () is arranged between the piezoelectric transceiver and the tool housing, and the element is arranged in abutment with the first face of the piezoelectric transceiver and the inner face of the housing, so that the tool housing acts as a transducer when the piezoelectric transceiver is activated and enlarges in a radial direction of the tool housing, forcing the tool housing outwards and sending a signal through the well fluid. The present invention also relates to a downhole system and a communication method.
