    • A headset of the invention can achieve high-quality sound reproduction over a wide band while allowing sound from the outside to be sufficiently heard. The headset includes at least one vibrator configured to vibrate in accordance with an electric signal. The headset also includes at least one diaphragm each being associated with the respective vibrator. The headset also includes a holding unit that, when worn on a head of a user, holds the diaphragm such that at least part of the diaphragm is spaced from a side surface of the head by a predetermined distance. When the headset has two diaphragms, the holding unit may also function as a linking member that links the two diaphragms.
    • 本发明的耳机可以在宽带上实现高质量的声音再现,同时可以充分地听到来自外部的声音。 耳机包括至少一个被配置为根据电信号振动的振动器。 耳机还包括至少一个隔膜,每个隔膜与相应的振动器相关联。 耳机还包括保持单元,该保持单元当佩戴在用户的头部上时,保持隔膜,使得隔膜的至少一部分与头部的侧表面间隔预定距离。 当耳机具有两个隔膜时,保持单元还可以用作连接两个隔膜的连接构件。

    • A spindle device of machine tool includes a pressure sensor (31) that detects a pressing force to a rod (18) by a drive (25), a displacement sensor (32) that detects displacement of the rod (18), a tool clamping-force detector (33) that detects a clamping force to a tool (19) by a collet (20) based on the pressing force to the rod (18) and the displacement of the rod (18), and a spring-replacement-timing determining unit (36) that determines a replacement timing of disc springs (24) based on the tool clamping force and a preset biasing force characteristic value of the disc springs (24), thereby allowing highly accurate determination of a replacement timing of a biasing unit by appropriately detecting a tool clamping force.
    • 机床的主轴装置包括:压力传感器(31),其通过驱动器(25)检测对杆(18)的按压力;位移传感器(32),其检测杆(18)的位移;工具夹紧 力检测器(33),其基于对所述杆(18)的按压力和所述杆(18)的位移,通过夹头(20)检测到对工具(19)的夹紧力,以及弹簧 - 定时确定单元(36),其基于所述工具夹紧力和所述盘簧(24)的预设偏置力特性值来确定盘簧(24)的更换定时,由此允许高精度地确定偏置的更换定时 通过适当地检测工具夹紧力来实现。
