Description

一种助听装置 技术领域
本发明涉及一种助听装置。
背景技术
现有的助听器由麦克风、微型扬声器和声音信号处理单元、电池等组成。由于人耳负荷的原因，助听器不能做的太过庞大，否则人耳不堪重负，另一方面，助听器做的稍微大一点，还就可能会给佩戴者造成佩戴歧视，所以现有助听器设备都尽可能做的小，这就限制了其信号处理***的能力不能太强，并且电池也选用高端的金属空气电池，能耗也不能太高，这样的妥协结果使得这种助听效果非常有限，经常出现噪声严重，听觉畸变等问题。
发明内容
本发明的发明目的在于提供一种助听装置，使用方便，有效提高助听效果。
实现本发明目的的技术方案：
一种助听装置，包括麦克风、微型扬声器和声音信号处理单元，其特征在于：麦克风和微型扬声器组成耳机，麦克风和微型扬声器之间设有隔离腔；还包括助听终端，声音信号处理单元设置于助听终端内，麦克风的信号输出端经ADC模块接声音信号处理单元的信号输入端，声音信号处理单元的信号输出端经DAC模块接微信扬声器。
所说的助听终端可以为手机。
声音信号处理单元与DAC模块之间设有声音测量模块。
声音信号处理单元、ADC模块、DAC模块、声音测量模块均位于助听终端内，助听终端与耳机有线连接。
声音信号处理单元、声音测量模块位于助听终端内，ADC模块、DAC模块设置于耳机上，助听终端与耳机无线连接，耳机和助听终端上均设有无线发送模块和无线接收模块。

本发明具有的有益效果：
本发明将麦克风和微型扬声器组成耳机形式，方便佩戴使用，有效避免了佩戴歧视。本发明由于将麦克风和微型扬声器组成耳机，可将声音信号处理单元单独设置于助听终端上，具有更强的声音处理能力，获得更佳的助听效果。本发明声音信号处理单元与DAC模块之间设 有声音测量模块，在用户首次使用时，该模块通过耳机播放不同频率不同响度的基准信号，来测试用户耳朵的听力能力曲线，在后续的助听过程中就可以借助该听力能力曲线进行听力补偿，获得更佳的助听体验。本发明助听终端与耳机可实现有线或无线连接，进一步方便使用。本发明助听终端可以是手机，将声音信号处理单元、ADC模块、DAC模块、声音测量模块设置于手机内，实现一机多用，使用方便。
