摘要： In an electro-acoustic transducer 100 which is an oscillator device, center positions of principal surfaces of piezoelectric elements 130 that are positioned on both surfaces of an elastic member 120 are different from each other. As such, since the two piezoelectric elements 130 are disposed asymmetrically on the upper and lower sides in the electro-acoustic transducer 100, it is possible to prevent vibrations of reversed phases at the time of divided vibration in which the reversed phases overlap with each other. In other words, since it is possible to prevent the generation of sound waves due to the vibration of local reversed phases, the sound pressure level can be improved.

摘要： An object is to provide an audio circuit in which flow of excessive current through a capacitive speaker and a drive circuit thereof can be prevented while degradation of sound quality of high-pitched tones is suppressed. The audio circuit for driving a capacitive speaker includes: a weighting circuit for performing weighting in conformity with frequency components of an audio signal; and a signal-voltage limiting compression circuit for compressing a signal, which is input to the drive amplifier or which has been output from the drive circuit, at a prescribed compression ratio in accordance with a difference voltage between the output signal of the weighting circuit and a preset threshold voltage when the weighted signal exceeds the threshold voltage. Alternatively, the audio circuit is provided with a signal-voltage limiting compression circuit for passing, with amplitudes unchanged, signal components below a prescribed frequency contained in the signal reproduced by the capacitive speaker and compressing amplitudes of signal components not less than the prescribed frequency at a prescribed compression ratio.

摘要： A mobile phone (100) detects at least a direction of an utterance position of a user from the voice input to a plurality of microphones (121,122) and controls an output direction of a voice out of a speaker unit (110) to match the detected utterance position.

The microphones may form a matrix together with piezoelectric vibrators that form a speaker unit, or may be formed separately from the speaker unit.
