摘要： The earphone is an earphone including a speaker unit configured to electroacoustically transduce an audio signal into a sound wave, and a housing configured to define an acoustic space on at least one side of a diaphragm of the speaker unit, the speaker unit being attached to the inside of the housing. The housing includes a nozzle portion forming an acoustic path communicating with the acoustic space to guide the sound wave to the ear canal of the user. The nozzle portion includes a base member made of a first metal material and defining an outer shell of the nozzle portion, and a tubular member of which outer wall surface is fixed to an inner wall surface of the base member to form the acoustic path on the inside and which is made of a second metal material different from the first metal material.
摘要翻译：耳机是耳机，其包括被配置为将声音信号电声转换成声波的扬声器单元以及被配置为在扬声器单元的振动膜的至少一侧上限定声学空间的壳体，扬声器单元被附接到在房屋内。壳体包括形成与声学空间连通的声学路径的喷嘴部分，以将声波引导到用户的耳道。喷嘴部包括：由第一金属材料制成并且限定喷嘴部的外壳的基部构件;以及管状构件，其外壁表面固定到基部构件的内壁表面以在第二构件上形成声学路径内部并且由不同于第一金属材料的第二金属材料制成。

摘要： There are provided headphones and a speaker unit having proper acoustic properties and exhibiting excellent reproduced sound quality even in the case of providing air holes at a damping member. The headphones include a speaker unit having a diaphragm and a frame supporting an outer peripheral portion of the diaphragm, a housing configured to house the speaker unit, and a damping member made of a material exhibiting air permeability and attached to cover an opening of the frame through which a sound wave emitted from the diaphragm passes and/or an opening of the housing. The damping member has one or more air holes formed by removal of the material forming the damping member. A secondary damping member is attached to an annular edge portion defining each air hole, thereby reducing vibration of the edge portion.
