Abstract: A karaoke apparatus and the method thereof are provided, which guarantees the pitch of the karaoke music conforms to the pitch of the user. The apparatus comprises an audio input unit, a scale detector, a memory unit, a processor and a scale control unit. The audio input unit receives a test sound. The scale detector analyzes at least one test step of the test sound. The memory unit stores a plurality of standard steps. The processor finds out the highest step among the test steps, compares the highest step with the standard steps, and obtains a target step from the comparison; wherein, the target step is the standard step closest to the highest step. Finally, the scale control unit adjusts the pitch of the karaoke music so that the pitch is lower than that of the target step.

Abstract: A voice control method is provided, which includes the following steps. First, a sound signal is received, wherein the sound signal includes a voice signal and a predetermined signal. Next, and electronic device is used to filer the predetermined signal to acquire the voice signal from the sound signal. Next, the voice signal is compared with several sample signals. Finally, the electronic device implements a corresponding action according to the result of the voice comparison. When the voice comparison is successful, the electronic device implements a corresponding control command according to the corresponding sample signal of the voice signal. On the other hand, when the voice comparison fails, the electronic device displays a predetermined string on the frame.

Abstract: An audio/video device is provided. The audio/video device includes a first locking part, a first sound-transmitting unit, a second locking part, a second sound-transmitting unit and an amplifier. The first sound-transmitting unit outputs an audio signal. The second sound-transmitting unit and the first sound-transmitting unit output the same audio signal. The amplifier has a joint part and a speaker unit. The joint part is jointed with the first locking part or the second locking part. When the joint part is jointed with the first locking part, the speaker unit is electrically connected to the first sound-transmitting unit for broadcasting an audio signal. When the joint part is jointed with the second locking part, the speaker unit is electrically connected to the second sound-transmitting unit for broadcasting an audio signal.

Abstract: An LVDS switch control device for a portable apparatus is disclosed, which has an LVDS transducer, which transforms the image information for the portable apparatus into LVDS signals; a buffer receiving the LVDS signals transmitted by the connection pedestal as the portable apparatus is assembled on the connection pedestal; a detector producing a correct assembling signal as the portable apparatus is correctly assembled on the connection pedestal; and an LVDS switcher having a first input end, a second input end and an output end, wherein the first input end connects with the detector. When the detector produces the correct assembling signal, the output end of the LVDS switcher will produce a signal that disables the LVDS transducer and enables the buffer so that the LVDS signals outputted by the connection pedestal will be transmitted to a display panel of the portable apparatus.

Abstract: An auxiliary device for operating both M-DOC series flash memory and non-X86 system processor in synchronism is provided. The auxiliary device comprises a first logic circuit enabled by a first address line of the non-X86 system processor for changing output thereof from a first level to a second level, a delay circuit for delaying the second level output of the first logic circuit a predetermined period of time prior to clearing the first logic circuit for changing output thereof from a second level to a first level, and a second logic circuit for performing a logical operation on the output of the first logic circuit and a CS pin of the non-X86 system processor prior to coupling to a CS pin of the M-DOC series flash memory. The M-DOC series flash memory thus can be used as both a power on memory and a typical memory.

Abstract: A portable electronic device capable of protecting a specific block of flash memory chips thereof is disclosed. It comprises at least one flash memory chip, a processor, and a programmable logic device. The flash memory chip stores a bootstrap, an embedded OS, and applications. The processor executes the bootstrap, the embedded OS, and the applications. The programmable logic device decodes address lines, write signals, and read signals of the processor so that when the processor is about to write data into the predetermined block of the flash memory chip, the programmable logic device neither generates a RDY# signal nor sends the RDY# signal to the processor for representing a write failure, and a write signal into the flash memory chip is masked so that the block of the flash memory chip is protected.
