摘要： Ultrasonic transducers that are capable of generating increased levels of ultrasound, as well as receiving ultrasonic waves with increased sensitivity. The ultrasonic transducers include a back cover, a protective front cover, a backplate, and a vibrator film layer disposed between the backplate and the protective front cover. The backplate includes a plurality of grooves formed on a surface thereof facing the vibrator film layer. Each groove includes upper edges having cross-sectional contours that gradually tend toward the deepest part of the groove to allow a larger area of the backplate to be closer to the vibrator film layer, thereby increasing the resulting electric field, and, consequently, increasing the output power and sensitivity of the ultrasonic transducer.

摘要： The invention is directed to a folded electrostatic speaker. An exemplary speaker comprises: a first membrane; a first electrode; a second membrane, at least a portion of the first membrane being connected to at least a portion of the second membrane; a second electrode; and a first opening defined between at least a portion of the first and second membranes for receiving and releasing air. At least a portion of the first membrane and at least a portion of the second membrane move substantially perpendicularly to at least a portion of the first opening. At least a portion of the first membrane moves towards at least a portion of the second membrane or away from at least a portion of the second membrane.

摘要： Techniques described herein generally relate to generating an audio signal with a speaker. In some examples, a speaker device is described that includes a membrane and a shutter. The membrane can be configured to oscillate along a first directional path and at a first frequency effective to generate an ultrasonic acoustic signal. The shutter can be positioned about the membrane and configured to modulate the ultrasonic acoustic signal such that an audio signal can be generated.

摘要： In a sitting room (70) are five speakers (SC, SL, SR, SBL, SBR) which are positioned upon a floor (FF), and a flat speaker (SF) which is positioned upon the ceiling (WU), so as to surround a viewer (P). An audio characteristic control device (10) executes a filter process which attenuates a peak (P RH ) of a band subject to attenuation (W RH ) in a signal (MD C ), treating the speaker (SC), among the five speakers (SC, SL, SR, SBL, SBR), which is in front of the viewer (P) as the destination thereof, and radiates a signal (MD SF ) via the filter process from the speaker (SF) as a plane wave. The band subject to attenuation (W RH ) is treated as a band which has a feature value which has an impact on the orientation of the height direction in a head part transfer function (H) of the viewer (P).

摘要： A electrostatic speaker (ESL) system may include a damping screen placed adjacent an outside surface of at least one of its stators. The damping screen reduces distortion of acoustic output rendered by the speaker's diaphragm. The distortion includes effects of resonance of the diaphragm. A resilient excursion limiter may be placed adjacent an inside surface of at least one of the stators to prevent contact of the diaphragm with the stator. A conductive portion of the diaphragm may be printed with a conductive ink layer that includes conductive nanofibers. The speaker system may include a dipole-radiating ESL element, an unbaffled or partially baffled dynamic speaker and a baffled monopole-radiating dynamic speaker (subwoofer), all essentially co- planar. The unbaffled or partially baffled dynamic speaker provides a smooth transition in sound between the dipole-radiating ESL element and the monopole-radiating subwoofer. The ESL system may include two or more invertedly-driven ESL elements of different sizes, each element handling a different range of frequencies.
