    • An apparatus and a method for testing a sound card are applicable for detecting whether a sound leakage problem occurs to a sounding interface of the sound card. The testing apparatus includes a switching circuit and a switching unit. The switching circuit is electrically connected to the sounding interface and a sound-receiving interface of the sound card respectively, and has a plurality of transfer paths. The switching circuit is used to receive a first and a second sound channel, and to connect the first and the second sound channel to corresponding transfer paths, so as to transmit the audio signal back to the sound-receiving interface. The switching unit is electrically connected to the sounding interface and the switching circuit, for receiving the first and the second sound channel. The switching unit alters the transfer paths in the switching circuit according to a first and/or a second switching audio signal.
    • 用于测试声卡的装置和方法适用于检测声卡的声音接口是否发生声音泄漏问题。 测试装置包括开关电路和开关单元。 开关电路分别电连接到声音接口和声卡的声音接收接口,并且具有多个传送路径。 开关电路用于接收第一和第二声道,并且将第一和第二声音通道连接到相应的传送路径,以将音频信号发送回声音接收接口。 开关单元电连接到探测接口和开关电路,用于接收第一和第二声道。 开关单元根据第一和/或第二切换音频信号来改变开关电路中的传输路径。

    • An electronic device with automatic switching input interfaces and a switching method thereof. The electronic device supports an Advanced Configuration Power Interface (ACPI), and includes a display unit, a storage unit, a memory unit, and an embedded controller. The display unit can be changed to a first position or a second position, and sends a signal to an embedded control unit when the display unit is at different positions. A management program running in the electronic device queries the ACPI and the embedded control unit to check the position and state of the display unit, so as to automatically load and run a corresponding program of a virtual input interface or a physical input interface into the memory unit, and remove the other program from the memory unit at the same time.

    • The present invention is to provide a magnetic lock mountable on an electronic device, which comprises an upper and a lower magnetic plates respectively formed on an upper and a lower housings of the electronic device, enabling the electronic device to be automatically locked due to the attraction between a plurality of magnetic members disposed on the corresponding positions of the upper and lower magnetic plates having different polarities when the upper housing is covered the lower housing. Alternatively, when the upper magnetic plate is moved a predetermined distance, the corresponding magnetic members on the upper and lower magnetic plates are in turn having the same polarity to repel with each other, enabling the upper and lower housings of the electronic device to be automatically unlocked.
    • 本发明提供一种可安装在电子设备上的磁性锁,其包括分别形成在电子设备的上壳体和下壳体上的上和下磁性板,使得电子设备能够由于吸引力自动地锁定 在上壳体被下壳体覆盖时,设置在具有不同极性的上磁板和下磁板的相应位置上的多个磁性构件之间。 或者,当上部磁性板移动预定距离时,上部和下部磁性板上的相应的磁性构件又具有相同的极性以相互排斥,使得电子装置的上部和下部壳体能够自动地 解锁。
