PROBLEM TO BE SOLVED: To provide an electromechanical transducer which can correct or compensate a fluctuation in the transmission/reception characteristics of an elastic wave transmitting/receiving means due to applied pressure.SOLUTION: The electromechanical transducer 102 which transmits/receives elastic waves such as ultrasound includes the elastic wave transmitting/receiving means 201 for transmitting/receiving the elastic waves, a pressure detecting means 203 for detecting pressure that is applied to the elastic wave transmitting/receiving means, and a correcting means 202, 204. Based on pressure information which is detected by the pressure detecting means, the correcting means performs at least one of a correction of elastic wave transmitted/received signals relevant to the elastic wave transmitting/receiving means and a correction of the transmission/reception characteristics of the elastic wave transmitting/receiving means.COPYRIGHT: (C)2011,JPO&INPIT【課題】加わる圧力による弾性波送受信手段の送受信特性の変動を補正ないし補償することができる電気機械変換装置を提供する。【解決手段】超音波などの弾性波の送受信を行う電気機械変換装置102は、弾性波を送受信する弾性波送受信手段201と、弾性波送受信手段に加わる圧力を検出する圧力検出手段203と、補正手段202、204と、を有する。補正手段は、圧力検出手段により検出された圧力情報を基に、弾性波送受信手段に係る弾性波送受信信号の補正と弾性波送受信手段の送受信特性の補正との少なくとも一方の補正を行う。【選択図】図1
