    • There are provided an oscillation device that outputs a sound wave; a recognition unit that recognizes a direction in which sound output targets (80), for which a sound is to be output, are located; a selection unit that selects at least one of the sound output targets (80) ; a distance calculation unit that calculates a distance to the sound output target (80) ; and a control unit that controls the oscillation device to adjust sound pressure of the sound wave. The oscillation device outputs an ultrasonic wave for a sensor and a sound wave for sound reproduction. The distance calculation unit calculates a distance between the oscillation device and an object to be selected (82) by detecting the ultrasonic wave for a sensor reflected from the object to be selected (82) selected by the selection unit. The control unit adjusts the magnitude of the output of the sound wave for sound reproduction on the basis of the calculated distance between the oscillation device and the object to be selected (82).
    • 提供了一种输出声波的振荡装置; 识别单元,其识别声音将被输出的声音输出目标(80)所处的方向; 选择单元,其选择所述声音输出目标(80)中的至少一个; 距离计算单元,其计算到所述声音输出目标(80)的距离; 以及控制单元,控制振荡装置以调节声波的声压。 振荡装置输出用于传感器的超声波和用于声音再现的声波。 距离计算单元通过检测由选择单元选择的待选对象(82)反射的用于传感器的超声波来计算振荡装置与待选对象(82)之间的距离。 控制单元基于计算出的振荡装置和待选对象之间的距离(82)来调整用于声音再现的声波的输出的大小。

    • An input apparatus (for example, a mobile terminal apparatus (100)) includes a display unit (60) that displays a plurality of operation position displays (for example, operation position displays (61 to 66)); and a detection unit that contactlessly detects an operation which corresponds to an operation position set in a specific space of a front of the input apparatus in correspondence to each of the plurality of operation position displays. The detection unit includes a first piezoelectric element (an oscillation piezoelectric element (31)) that oscillates ultrasound toward the front space of the input apparatus; a second piezoelectric element (a reception piezoelectric element (21)) that detects the ultrasound which is oscillated by the first piezoelectric element; and a determination unit that determines whether or not an operation is performed on a certain operation position based on a result of detection performed by the second piezoelectric element.
    • 输入装置(例如便携式终端装置(100))具有显示多个操作位置显示(例如操作位置显示(61〜66))的显示部(60)。 以及检测单元,其对应于所述多个操作位置显示器中的每一个,以非接触方式检测与在所述输入装置的前方的特定空间中设定的操作位置相对应的操作。 检测单元包括朝向输入设备的前部空间振动超声波的第一压电元件(振荡压电元件(31)); 检测由第一压电元件振荡的超声波的第二压电元件(接收用压电元件(21)); 以及确定单元,其基于由第二压电元件执行的检测结果来确定是否对特定操作位置执行操作。
