1、前言

无线耳机是中间的线被电波代替,是从电脑的音频出口连接到发射端,再由发射端通过电波发送到接受端的耳机中,接受端就是相当于是一个收音机。主要分为三种类型: 蓝牙耳机、红外线耳机、2.4G 耳机。无线耳机分为三个部分:第一部分是发声源,第二部分是接受器,第三部分是耳机部分,这部分的功能主要是用来将手机或接收器传送来的信号转化为声音再传到人的耳朵里。

2、方案概述

Ameya360 无线耳机解决方案采用数字化主动降噪技术,将 ANC 与智能控制技术、智能材料和光纤技术结合起来,既提高了主动降噪系统的性能,又保证系统控制的性能。主要由充电接口电路、电池电路、蓝牙收发模块、音频组件、按键电路、受话电路、状态灯、
电池、紧扣外壳等部件组成。耳机上有一个外置麦克风,但不是用来通话。这枚麦克风会进行外部的收音,在经过 DSP 信号处理器以及手机上 App 选项配套算法的处理之后,移除一些声波,将特定声波形变或加强来改变原来的声音成果。在原声和附加信号汇聚,在整合起来输出给耳朵。

无线耳机全程选用无线连接,拥有蓝牙自动连接功能,配套多样尺寸耳塞。六小时续航能力,一小时充满。通过耳机能大幅度降低一些特定噪音的音量,换句话说,戴上智能耳机,你不但能轻松忽视周遭不想听到的噪音,也有助于你听清楚想听到的内容。
