Abstract: An electro-acoustic transducer is disclosed. The electro-acoustic transducer includes an electret diaphragm, an orifice plate and a plurality of dividing structures. Each of the dividing structures, disposed between the electret diaphragm and the orifice plate, includes at least one main portion, and the number of the main portion is a positive integer. When the number of the main portion is larger than one, the main portions are respectively connected to a center and extended radially from the center.

Abstract: An electronic device is provided, including a conductive substrate, an electret diaphragm, a plurality of spacers, a first electrode, and two second electrodes. The conductive substrate has a plurality of openings. The spacers are disposed between the conductive substrate and the electret diaphragm to define an acoustic projecting portion and two acoustic receiving portions on the electret diaphragm. The first electrode is disposed on the acoustic projecting portion and coupled with the conductive substrate for generating an acoustic signal. The second electrodes are disposed on the acoustic receiving portions and coupled with the conductive substrate, wherein the acoustic receiving portions receive the acoustic signal and vibrate to vary an electrical field between the second electrodes and the conductive substrate.

Abstract: The present invention relates to a user device: a processor (20) configured to process an audio signal to derive a first driving signal and a second driving signal, such that the first driving signal comprises only components of the audio signal having frequencies higher than a threshold frequency and such that the second driving signal comprises components of the audio signal having frequencies above and below the threshold frequency; wherein the processor is configured to simultaneously provide the first driving signal and the second driving signal; a first speaker (30), being configured to generate sound based on the first driving signal; and a second speaker (40), being configured to generate sound based on the second driving signal. Furthermore, the present invention also relates to a corresponding method, a computer program, and a computer program product.
