    • There is provided an electronic component excellent in moisture resistance capable of ensuring electrical connection between electrodes and hermeticity of a sealed region including a vibrating part and suppressing an increase in size. An electronic component including a piezoelectric element provided with a vibrating part and a first electrode on one face of a piezoelectric substrate and a printed circuit substrate having a second electrode is constituted by including: a bump provided in advance on one of the first electrode and the second electrode and connected to the other of the first electrode and the second electrode; an annular first metal layer surrounding the vibrating part; and a solder material with a solidus temperature lower than the bump, sealing a space between the first metal layer and the printed circuit substrate to make a placement region of the vibrating part a hermetic space, whereby moisture permeation into the hermetic space and the outward spread of the solder material can be suppressed, and a space for the bump to spread by being melted can be omitted. Moreover, the electrical connection between the electrodes and the sealing of the placement region can be performed in separate processes, so that high hermeticity can be obtained.
    • 提供了一种能够确保电极之间的电连接和包括振动部分的密封区域的密封性并且抑制尺寸增加的耐湿性优异的电子部件。 包括在压电基板的一个表面上设置有振动部分和第一电极的压电元件的电子部件和具有第二电极的印刷电路基板包括:预先设置在第一电极和第二电极之一上的凸块 第二电极,并连接到第一电极和第二电极中的另一个; 围绕所述振动部的环状的第一金属层; 以及固体线温度低于凸点的焊料,密封第一金属层与印刷电路基板之间的空间,使振动部的放置区域成为密封空间,由此水分渗入密封空间和向外扩展 可以抑制焊料材料,并且可以省略通过熔化扩散的凸起的空间。 此外,电极之间的电连接和放置区域的密封可以在单独的工艺中进行,从而可以获得高密封性。

    • Electronic keyboard instrument is provided with a leg section supporting thereon a keyboard in such a manner that the keyboard is located at a height falling within a range from 350 mm to 500 mm. Namely, the leg section supports thereon the keyboard at a suitable height that is substantially equal to an average height of ordinary low tables designed on the assumption that they are generally used when users are in a comfortable position. Namely, the “height falling within a range from 350 mm to 500 mm” is derived from survey results of heights of low tables. Thus, when the user sits in front of the keyboard instrument, the user can take a comfortable position as when sitting in front of a low table, and, even in such a comfortable position, the keyboard is located at a right height for playing. With such arrangements, the user is allowed, at any desired time, to readily enjoy playing the instrument in a natural playing posture.
    • 电子键盘乐器设有支撑键盘的腿部,键盘位于350mm至500mm范围内的高度。 也就是说,腿部在其上以适当的高度支撑键盘,该适当的高度基本上等于在使用者处于舒适的位置时通常使用的普通低表的平均高度。 也就是说,“高度在350mm至500mm的范围内的高度”是根据低表的高度的测量结果得出的。 因此,当用户坐在键盘乐器的前面时,使用者可以坐在低桌子前方的舒适位置,即使在这样舒适的位置,键盘位于正确的高度进行播放。 通过这样的布置,用户可以在任何期望的时间容易地以自然的演奏姿势欣赏乐器的演奏。
