摘要： This invention relates to acoustic drivers with stationary and moving coils. Time varying signals are applied to the moving and stationary coils to control the movement of a diaphragm, which produces audible sound. The time varying signals correspond to an input audio signal such that the sound corresponds to the input audio signal. Some of the described embodiments include multiple moving coils, multiple stationary coils or both. Some embodiments include feedback for adjusting one or more of the signals based on a characteristic of the acoustic driver. Various compensation and other features of the invention are also described in relation to various embodiments.

摘要： System, device, and method of sound isolation and signal enhancement. A hybrid device, or hybrid microphone, or a directional hybrid acoustic-and-optical microphone device, includes: a laser microphone to transmit a laser beam towards a sound-source, and to receive optical feedback reflected from a vibrating surface of the sound-source; an acoustic microphone to capture an acoustic signal which includes (i) sounds produced by the sound-source, and (ii) other concurrent sounds produced externally to the sound-source; a processing unit (a) to process the received optical feedback, and (b) to dynamically enhance the acoustic signal based on the received optical feedback. The processing unit includes or utilizes a digital filter constructor module to dynamically construct, based on the received optical feedback and based on the acoustic signals captured by the acoustic microphone, a digital filter to filter the other concurrent noises from the acoustic signal.

摘要： The invention relates to a MEMS loudspeaker (1) for generating sound waves in the audible wavelength spectrum, with a carrier substrate (2) that features a sub-strate cavity (6) with two substrate openings (7, 8), which are formed on two opposite sides of the carrier substrate (2), an actuator structure (3), in particular a piezoelectric actuator structure, which is arranged in the area of one of the two substrate openings (7, 8) and is connected to the carrier substrate (2) in its edge area, and a membrane (4) anchored in its edge area, which, by means of the actuator structure (3), can be set into vibration for generating sound waves. In accordance with the invention, in a cross-sectional view of the MEMS loudspeaker (1), the membrane (4) is spaced at a distance from the actuator structure (3), such that an intermediate cavity (13) is formed between these two. Furthermore, the MEMS loudspeaker (1) features a coupling element (13) arranged in the intermediate cavity (13), which connects the actuator structure (3) to the membrane (4) and may vibrate with this with respect to the carrier substrate (2).

摘要： The invention relates to a MEMS sound transducer (2) for generating and/or detecting sound waves in the audible wavelength spectrum with a membrane carrier (40), a membrane (30) that is connected in its edge area (37) to the membrane carrier, and may vibrate along the z-axis (50) with respect to the membrane carrier, and a stopper mechanism (60), which limits the vibrations of the membrane in at least one direction (51). In accordance with the invention, the MEMS sound transducer is characterized by the fact that the stopper mechanism at least features one reinforcing element (31) that is arranged on one side of the membrane, and an end stop (61) opposite to the reinforcing element, which is spaced at a distance from it in a neutral position of the membrane and against which the reinforcing element abuts at a maximum deflection.
