    • An audio signal measurement method for a speaker and an electronic apparatus having the speaker are provided. The electronic apparatus further has a processing circuit and a power amplifier. The processing circuit is coupled to the speaker and configured to execute a time domain to frequency domain transform according to a voltage value of an audio signal and a current value of current feedback from the speaker so as to obtain a frequency response curve. The power amplifier is coupled to the speaker and configured to drive the speaker according the voltage value of the audio signal. The processing circuit is capable of determining whether the frequency response curve is located within a predetermined area such that the processing circuit generates a signal when the frequency response curve is located out of the predetermined area. Thereby, the electronic apparatus may measure its transducer distortion and acoustic box leakage.
    • 提供了一种用于具有扬声器的扬声器和电子设备的音频信号测量方法。 电子设备还具有处理电路和功率放大器。 处理电路耦合到扬声器,并且被配置为根据音频信号的电压值和来自扬声器的电流反馈的当前值执行时域到频域变换,以获得频率响应曲线。 功率放大器耦合到扬声器并且被配置成根据音频信号的电压值来驱动扬声器。 处理电路能够确定频率响应曲线是否位于预定区域内,使得当频率响应曲线位于预定区域之外时处理电路产生信号。 因此,电子设备可以测量其换能器失真和声箱泄漏。

    • A portable electronic apparatus and a connection method therefore are disclosed. The portable electronic apparatus comprises a connector, a processing circuit, and a switch module. After a plug is plugged into the connector, the processing circuit reads a voltage value of the plug via the switch module. When determining that the voltage value of the plug is within a first voltage range, the processing circuit outputs switch signals to the switch module, so that an input signal of the plug is able to be transmitted to the processing circuit via the connector and the switch module. When determining that the voltage value of the plug is within a second voltage range, the processing circuit outputs other switch signals to the switch module, so that an output signal of the processing circuit is able to be transmitted to the plug via the switch module and the connector.
    • 因此,公开了一种便携式电子设备和连接方法。 便携式电子设备包括连接器,处理电路和开关模块。 插头插入连接器后,处理电路通过开关模块读取插头的电压值。 当确定插头的电压值在第一电压范围内时,处理电路将开关信号输出到开关模块,使得插头的输入信号能够经由连接器和开关发送到处理电路 模块。 当确定插头的电压值在第二电压范围内时,处理电路向开关模块输出其他开关信号,使得处理电路的输出信号能够通过开关模块传送到插头, 连接器。
