电子设备及基于MICRO-USB接口的外接功率放大模块识别方法
摘要：
一种电子设备，包括MICRO-USB接口、外接功率放大模块、数字逻辑检测模块、模拟信号检测模块、电源信号输出模块、声音信号输出模块以及控制模块，控制模块在数字逻辑检测模块获取的数字逻辑为0时，判定有外接模块插入至MICRO-USB接口中，并进一步控制模拟信号检测模块获取ID端的模拟电压值，在模拟电压值不为0V时，判定外接模块为外接功率放大模块，并控制电源信号输出模块输出电源信号至外接功率放大模块，控制声音信号输出模块输出声音信号至外接功率放大模块。本发明进一步提供一种基于MICRO-USB接口的外接功率放大模块识别方法。通过以上方式，本发明所提供的技术方案可在节约成本的同时亦简化了电路结构。
摘要（英）：

The invention provides electronic equipment which comprises an MICRO-USB interface, an external power amplification module, a digital logic detection module, an analog signal detection module, a power supply signal output module, a sound signal output module and a control module, wherein when digital logic acquired by the digital logic detection module is 0, the control module determines that an external module is plugged into the MICRO-USB interface and then controls the analog signal detection module to acquire an analog voltage value of an ID end; and when the analog voltage value is not 0V, the control module determines that the external module is the external power amplification module, controls the power supply signal output module to output a power supply signal to the external power amplification module, and controls the sound signal output module to output a sound signal to the external power amplification module. The invention also provides a method for identifying the external power amplification module based on the MICRO-USB interface. By using the electronic equipment and the method in the technical scheme, the cost can be saved and a circuit structure can be simplified at the same time.
