Description

无源耳机
本实用新型涉及一种耳机,特别是一种无源耳机。
耳机是将音频电流信号输入到扬声器的发声装置,人们听音乐、听广播或接听电话常使用耳机。目前的耳是将扬声器置于耳塞中,使用时将耳塞放入人们耳孔中,实际上是将扬声器直接放入了入耳中,因此耳机听久了人们会觉得头昏脑涨,音质沉闷,加上扬声器耳塞的外壳材料通常是ABS等硬质塑料制作,耳朵有涨痛感。
本实用新型的目的在于提供一种声音清晰,不会产生痛昏脑涨,耳朵无涨痛感的无源耳机。
本实用新型的目的是这样实现的,一种无源耳机,包括扬声器、信号引线、插塞,其特点是中空软管的一端接有采用软质材料制作的听筒,中空软管的另一端接有扬声器罩,扬声器罩内腔与扬声器啮合。
插塞接入的音频电流信号使扬声器发出声音,扬声器发出的声音通过中空软管,经软管中的空气传输,将声音经插入耳朵的软质材料听筒传递给人的大脑,使人们听到音乐和声音,耳朵内不再塞入扬声器。
按本实用新型提供的无源耳机,声音清晰,与平时人们生活中的交谈声音无差别,不会产生头昏脑涨,而且耳朵不发涨,无涨痛感。
本实用新型的附图为无源耳机的结构示意图。
