手机700还可包括至少一种传感器750，比如光传感器、运动传感器以及其他传感器。在一个实施例中，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板741的亮度，接近传感器可在手机移动到耳边时，关闭显示面板741和/或背光。运动传感器可包括加速度传感器，通过加速度传感器可测量各个方向上加速度的大小，静止时可测量出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏切换)、振动识别相关功能(比如计步器、敲击)等。此外，手机还可配置陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器等。
音频电路760、扬声器761和传声器762可提供用户与手机之间的音频 接口。音频电路760可将接收到的音频数据转换后的电信号，传输到扬声器761，由扬声器761转换为声音信号输出；另一方面，传声器762将收集的声音信号转换为电信号，由音频电路760接收后转换为音频数据，再将音频数据输出处理器780处理后，经阵列天线710可以发送给另一手机，或者将音频数据输出至存储器720以便后续处理。
处理器780是手机的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器720内的软件程序和/或模块，以及调用存储在存储器720内的数据，执行手机的各种功能和处理数据，从而对手机进行整体监控。在一个实施例中，处理器780可包括一个或多个处理单元。在一个实施例中，处理器780可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等；调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器780中。
手机700还包括给各个部件供电的电源790(比如电池)，优选的，电源可以通过电源管理系统与处理器780逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
在一个实施例中，手机700还可以包括摄像头、蓝牙模块等。
本申请所使用的对存储器、存储、数据库或其它介质的任何引用可包括非易失性和/或易失性存储器。合适的非易失性存储器可包括只读存储器(ROM)、可编程ROM(PROM)、电可编程ROM(EPROM)、电可擦除可编程ROM(EEPROM)或闪存。易失性存储器可包括随机存取存储器(RAM)，它用作外部高速缓冲存储器。作为说明而非局限，RAM以多种形式可得，诸如静态RAM(SRAM)、动态RAM(DRAM)、同步DRAM(SDRAM)、双数据率 SDRAM(DDR SDRAM)、增强型SDRAM(ESDRAM)、同步链路(Synchlink)DRAM(SLDRAM)、存储器总线(Rambus)直接RAM(RDRAM)、直接存储器总线动态RAM(DRDRAM)、以及存储器总线动态RAM(RDRAM)。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
