摘要： A speaker system that includes an audio signal-receiving interface, a modulating circuit, a phase-control circuit, and a number of speaker units. The audio signal-receiving interface is configured to receive an audio signal, and the modulating circuit is coupled with the audio signal-receiving interface. The modulating circuit is configured to modulate a low frequency component of the audio signal and to generate a modulated signal. The phase-control circuit is coupled with the modulating circuit and the audio signal-receiving interface. The phase-control circuit is configured to receive the modulated signal and a high-frequency component of the audio signal and to control a phase of the modulated signal, a phase of the high-frequency component of the audio signal, or both. The speaker units are coupled with the phase-control circuit and configured to generate sound waves based on signals supplied by the phase-control circuit.

摘要： An ultrasound transducer has a cup-shaped casing. The cup-shaped casing has a sidewall. A cross section of an inner surface of the sidewall being perpendicular to a central axis of the ultrasound transducer substantially shows a dumbbell-shaped contour. The dumbbell-shaped contour has a pair of opposite straight-line sections being substantially parallel to a longitudinal axis of the dumbbell-shaped contour and a pair of opposite arc sections being located respectively at two ends of the longitudinal axis of the dumbbell-shaped contour and respectively forming two enlarged portions of the dumbbell-shaped contour. Two ends of each arc section of the dumbbell-shaped contour respectively joint the straight-line sections through two curve sections and each curve section is connected to one end of the arc section and one straight-line section. At least one enlarged area of a dumbbell-shaped surface of an inside bottom surface has a recessed portion.
摘要翻译：超声波换能器具有杯形壳体。杯形壳体具有侧壁。垂直于超声换能器的中心轴线的侧壁的内表面的横截面基本上呈现哑铃状轮廓。哑铃形轮廓具有一对相对的直线部分，其基本上平行于哑铃形轮廓的纵向轴线，并且一对相对的弧形部分分别位于哑铃形轮廓的纵向轴线的两端并且分别形成哑铃形轮廓的两个扩大部分。哑铃形轮廓的每个弧形部分的两端分别通过两个曲线部分连接直线部分，并且每个曲线部分连接到弧形部分的一端和一个直线部分。内底面的哑铃形表面的至少一个放大区域具有凹部。
