摘要： PURPOSE: A headphone including a stereo function is provided to save the purchasing cost of a consumer by simplifying the architectural design of a headphone. CONSTITUTION: A speaker(3) installs inside each of two lid covers(2). A transmission forms a Helmholtz resonance inside the lid covers. A vent of the transmission is located in the outer case of the lid cover in order to improve the low frequency resonance of the headphone stereo. A connection line(1) of the plug(11) is electrically connected to the speaker. An audio power amplifier(6) is installed on the connection line of the plug. A switch(8) switches a headphone mode and a stereo mode by switching different audio output power signal.
摘要翻译：目的：提供一种包括立体声功能的耳机，通过简化耳机的建筑设计来节省消费者的购买成本。构成：扬声器（3）安装在两个盖子盖（2）的内部。传输在盖盖内形成亥姆霍兹共振。传动装置的通风口位于盖罩的外壳中，以改善耳机立体声的低频谐振。插头（11）的连接线（1）电连接到扬声器。音频功率放大器（6）安装在插头的连接线上。开关（8）通过切换不同的音频输出功率信号来切换耳机模式和立体声模式。

摘要： PURPOSE: A key top of a keyboard is provided to ergonomically design a keyboard and eliminate a wasted space in the keyboard. CONSTITUTION: The device comprises a main typing area(11). The main typing area(11) includes plural columns separated by four horizontal lines(L1, L2, L3, L4). The arrangement of keys in the keyboard has the same structure as that in the conventional keyboard. The main typing area(11) can be separated into a right hand side portion and a left hand side portion by the "Y" key and the "H" key. Each key top in the left hand side portion has a shape of a parallelogram whose upper side is shifted to the right direction more than the lower side. Conversely, each key top in the right hand side portion has the upper side which is shifted to the left direction more than the lower side. The upper side and the lower side of all the key tops are parallel to the horizontal lines(L1, L2, L3, L4). The "Y" key and the "H" key have the shape of a trapezoid.
摘要翻译：目的：提供键盘的顶部，以人体工程学设计键盘，并消除键盘浪费的空间。规定：设备包括主打字区域（11）。主打字区域（11）包括由四条水平线（L1，L2，L3，L4）分开的多列。键盘中键的配置与常规键盘具有相同的结构。主打字区域（11）可以通过“Y”键和“H”键分离成右手侧部分和左手侧部分。左侧的各个键顶部具有平行四边形的形状，该平行四边形的上侧比下侧更向右侧方向移动。相反，右手侧部分中的每个键顶部具有比下侧更多地向左方向移动的上侧。所有键顶的上侧和下侧平行于水平线（L1，L2，L3，L4）。 “Y”键和“H”键的形状为梯形。
