    • 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.

    • 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.

    • 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).
    • 在休息室(70)中分别位于地板(FF)上的五个扬声器(SC,SL,SR,SBL,SBR)和位于天花板(WU)上的平板扬声器(SF) 围绕观看者(P)。 音频特征控制装置(10)执行滤波处理,该滤波处理在五个扬声器(MD)中对信号(MD C)中的衰减(W RH)的波段(P RH)进行衰减,处理扬声器(SC) SC,SL,SR,SBL,SBR),其作为目的地在观看者(P)的前方,并且经由来自扬声器(SF)的滤波处理的信号(MD SF)作为平面波发射。 经受衰减的频带(W RH)被视为具有对观看者(P)的头部传递函数(H)中的高度方向的取向具有影响的特征值的频带。
