Description

一种终端设备及调节音量的方法
技术领域
本发明涉及终端设备技术领域， 尤其涉及一种调节音量的方法及终端设 备。
背景技术
目前很多终端设备上釆用了距离感应器， 主要用于在拨打电话时， 熄灭 触摸屏幕， 以减少误操作。
距离感应器也称位移传感器， 原理是利用各种元件检测对象物的物理变 化量， 通过将该变化量换算为距离， 来测量从传感器到对象物的距离位移。 根据使用元件不同， 分为电感式传感器、 电容式传感器、 霍尔式传感器、 光 学式位移传感器、 线性接近传感器和超声波位移传感器等。
电感式传感器也叫涡流式传感器， 由三大部分组成： 振荡器、 开关电路 及放大输出电路。 振荡器产生一个交变磁场， 当金属目标接近这一磁场， 并 达到感应距离时， 在金属目标内产生涡流， 从而导致振荡衰减， 以至停振。 振荡器振荡及停振的变化被后级放大电路处理并转换成开关信号， 触发驱动 控制器件， 从而达到非接触式的检测目的。
光电式传感器利用的是光电效应。 将发光器件与光电器件按一定方向装 在同一个检测头内。 当有反光面 （被检测物体）接近时， 光电器件接收到反 射光后便在信号输出， 由此便可 "感知" 有物体接近。
线性接近传感器是一种属于金属感应的线性器件， 接通电源后， 在传感 器的感应面将产生一个交变磁场， 当金属物体接近此感应面时， 金属中则产 生涡流而吸取了振荡器的能量， 使振荡器输出幅度线性衰减， 然后根据衰减 量的变化来完成无接触检测物体的目的。

工业实用性
本实施方式通过电容式传感器感知人手的移近， 激活位于终端设备左侧 或右侧中部偏上位置的触控单元， 用户在触控单元上进行上下滑动操作， 触 控单元产生用户操作的触控信号， 将触控信号传输到音量调节器进行音量的 转换和放大处理， 得到控制信号， 处理器按照控制信号调节音量， 本实施方 式在终端设备上不设置音量按键的情况下， 实现对音量的调节。
利用上述技术方案， 在人手距离触控单元一定距离时， 激活触控单元， 通过触控单元方便地调节音量， 极大地提升了用户体验满意度。
