移动终端以及移动终端切换接听模式的方法  Mobile terminal and method for switching mobile terminal to answer mode
【技术领域】  [Technical Field]
本发明涉及移动通信技术， 特别是涉及一种移动终端以及移动终端切换接 听模式的方法。  The present invention relates to mobile communication technologies, and in particular, to a mobile terminal and a method for a mobile terminal to switch a listening mode.
【背景技术】 【Background technique】
诸如手机等移动终端， 已经成为人们比必可少的通信工具， 当人们在室外 吵杂的地方用移动终端通话时， 如果听筒声音不够大， 则需要打开移动终端的 扬声器进行通话， 回到安静的地方时， 又需要使用听筒通话。 或者是通话过程 中， 身边有其他人需要一起通话时， 就要打开移动终端的扬声器进行通话， 当 不需要他人参加通话时， 又需要使用听筒通话。 应对这些繁杂的操作， 传统做 法是： 在通话过程中， 通过使用移动终端上设置的按键（可以是硬件按钮也可 以使软件按钮） 进行切换， 这样使用起来非常的不方便。 而且现有技术中只通 过检测移动终端与使用者头部的距离来切换听筒和扬声器。 当用户不想进行切 换， 而移动终端与使用者头部又已经形成一定距离时， 就会造成误判。  Mobile terminals such as mobile phones have become less common communication tools. When people use mobile terminals to talk in a noisy place outdoors, if the handset sound is not loud enough, you need to open the speaker of the mobile terminal to make a call and return to the quiet. When you are in a place, you need to use the handset to talk. Or during a call, when someone else needs to talk together, you should open the speaker of the mobile terminal to make a call. When you do not need others to participate in the call, you need to use the handset to talk. To deal with these complicated operations, the traditional method is: During the call, it is very inconvenient to use by using the buttons set on the mobile terminal (which can be hardware buttons or software buttons). Moreover, in the prior art, the earpiece and the speaker are switched only by detecting the distance between the mobile terminal and the user's head. When the user does not want to switch, and the mobile terminal has formed a certain distance from the user's head, it will cause a false positive.
