Abstract

See full text

Provided is an electroacoustic transducer in which a decrease in sound pressure in a high sound band is suppressed and power consumption can be reduced, in an electroacoustic transducer in which a plurality of vibrators are arranged on a vibration plate. The electroacoustic transducer includes a vibration plate and a vibrator group consisting of a plurality of piezoelectric vibrators arranged on one surface of the vibration plate, in which the plurality of piezoelectric vibrators each belong to any one of a first group to an n-th group, an upper limit frequency of a frequency band of an input signal input to the piezoelectric vibrator is different for each group, and in a case where upper limit frequencies for each group are denoted by f1 to fn, the upper limit frequencies gradually decrease from the upper limit frequency f1 in the first group to the upper limit frequency fn in the n-th group.
