摘要： An ear piece to be detachably attached to a sound tube protruding from a housing of an earphone has a base portion with a through hole. The through hole has an inner wall with a first, a second, and a third portion continuously provided in order when viewed from the housing. The first portion protrudes inwardly and has a first distance from a protruding inner surface of the first portion to an axis line passing through the cross section of the base portion and the through hole. The second portion has a circumferential inner surface having a second distance longer than the first distance to the axis line. The third portion is formed continuously with the second portion, having a circumferential inner surface with a third distance longer than the second distance to the axis line.

摘要： A headphone housing has a first and a second summit in cross section. A sound emitter protrudes from the housing in side section. In the cross section, the first summit protrudes as being away from a point of intersection of an axis line of the sound emitter, that is horizontal and vertical to the side and cross sections, respectively, and a first straight line going through a cord guide located in an outer edge of the cross section, in a first side with respect to the first line and in a second side far from the cord guide with respect to a second straight line going through the point and intersecting with the first line. The second summit protrudes as being away from the point in the second side and in a third side, the opposite of the first side with respect to the first line.
摘要翻译：耳机壳体具有第一和第二顶部横截面。声音发射器从侧面部分的壳体突出。在横截面中，第一峰顶分别突出于远离声发射器的轴线的交点，水平和垂直于侧面和横截面，以及穿过帘线导向件的第一直线位于所述横截面的外边缘中，在相对于所述第一线的第一侧和相对于穿过所述点并与所述第一线相交的第二直线的远离所述绳索引导件的第二侧中。第二顶点突出为远离第二侧和第三侧的点，相对于第一线相对于第一侧。

摘要： An earphone includes a cylindrical portion having an opening in one end and an audio output unit which outputs sound from one face. The audio output unit is fixed to the cylindrical portion such that another face is in contact with an end face of the one end of the cylindrical portion. The audio output unit and the cylindrical portion are insertable at least partially in the external auditory canal of a human being. The earphone further includes a thin-wall part provided in the cylindrical portion and a ring, made of a material of a greater specific gravity than the cylindrical portion, which is fixed to the inner surface. The ring is fixed in a position such that the ring overlaps in the axial direction of the cylindrical portion with respect to the thin-wall part.
摘要翻译：耳机包括在一端具有开口的圆柱形部分和从一个面输出声音的音频输出单元。音频输出单元固定到圆柱形部分，使得另一个面与圆柱形部分的一端的端面接触。音频输出单元和圆柱形部分至少部分地可插入人的外耳道中。耳机还包括设置在圆筒形部分中的薄壁部分和由比固定在内表面上的比圆柱形部分更大比重的材料制成的环。环被固定在使得环相对于薄壁部在圆筒部的轴向上重叠的位置。

摘要： An earphone has a main body, a first tube portion that protrudes from the main body in a first direction, a speaker unit provided at a protruding top of the first tube portion, and a second tube portion that protrudes from the main body in a second direction that is different from the first direction. The second tube portion communicates with the first tube portion through the main body. The speaker unit is provided with a space at one side thereof. The space is formed in the first and second tube portions and extends from the protruding top of the first tube portion to a protruding top of the second tube portion through the main body.
