一种具有助听功能的手机

Abstract

本实用新型公开了一种具有助听功能的手机,包括机壳,安装在机壳内的主处理芯片,所述机壳内还安装有第一MIC、第二MIC、MIC降噪芯片和耳机功率放大芯片,所述第一MIC、第二MIC通过MIC降噪芯片与主处理芯片连接,所述主处理芯片与耳机功率放大芯片连接。本实用新型通过在手机内安装MIC降噪芯片和耳机功率放大芯片,以实现对输入音频信号中的背景噪音进行降噪过滤处理,并输出清晰的语音通话音频信号,并通过耳机功率放大芯片对该语音通话音频信号进行放大,由高频放大耳机直接输入。与现有技术相比,本实用新型结构简单、实现容易,能够有效解决听力存在障碍的用户使用手机的不便。
The utility model discloses a mobile phone with a hearing aid function, comprising a shell as well as a main processing chip, a first MIC, a second MIC, an MIC noise reduction chip and an earphone power amplifying chip which are installed in the shell. The first MIC and the second MIC are connected with the main processing chip through the MIC noise reduction chip, and the main processing chip is connected with the earphone power amplifying chip. In the utility model, through the MIC noise reduction chip and the earphone power amplifying chip which are installed in the mobile phone, noise reduction and filtering processing are carried out on background noise in input sound signals, and clear voice conversation audio signals are output. In addition, the voice conversation audio signal is amplified through the earphone power amplifying chip, and the amplified signals are directly input through a high-frequency amplification earphone. Compared with the prior art, the utility model has simple structure, is easy to realize, can effectively solve the problem that users who have dysaudia are inconvenient to use mobile phones.
