摘要: Operating an electrostatic acoustic device simultaneously as a speaker and as a microphone. The electrostatic acoustic device includes a membrane and an electrode disposed proximate to the membrane. An input varying audio signal is input to the electrostatic acoustic device. The membrane is configured to respond mechanically to a varying electric field responsive to the varying audio signal input. A portion of the input varying audio signal is tapped to produce a reference signal. A signal is detected responsive to motion of the membrane, to convert the signal to an output varying voltage signal. The output varying voltage signal is compared to the reference signal to produce a microphone signal. The microphone signal is responsive to motion of the membrane induced by air pressure variations of ambient sound.

摘要: Capacitive, MEMS-type acoustic transducer, having a sound collection part and a transduction part. A substrate region surrounds a first chamber arranged in the sound collection part and open towards the outside; a fixed structure is coupled to the substrate region; a cap region is coupled to the fixed structure. A sensitive membrane is arranged in the sound collection part, is coupled to the fixed structure and faces the first chamber. A transduction chamber is arranged in the transduction part, hermetically closed with respect to the outside and accommodates a detection membrane. An articulated structure extends between the sensitive membrane and the detection membrane, through the walls of the transduction chamber. A fixed electrode faces and is capacitively coupled to the detection membrane. Conducive electrical connection regions extend above the substrate region, into the transduction chamber.

摘要: The present invention relates to a diaphragm for sound generating devices and a preparation method thereof, and a sound generating device. The diaphragm for sound generating devices comprises only one layer of a thermoplastic polyester elastomer film, wherein the thermoplastic polyester elastomer is formed by copolymerization of a polyester hard segment which is prepared by reacting an aromatic dicarboxylic acid with a dihydric alcohol and a soft segment containing an aliphatic polycarbonate, and the diaphragm has a thickness of 10-200 □m, and a loss factor of 0.1-0.3 at a temperature of 23° C. The thermoplastic polyester elastomer used for the diaphragm of the present invention is composed of the polyester hard segment and the aliphatic polycarbonate soft segment, and such material not only solves the problem that the existing thermoplastic elastomers have poor resistances to high temperatures and chemicals, but also improves sensitivity, and can also well achieve the basic properties such as stiffness, resilience and damping required by vibration of the diaphragm.
