Abstract: An optical engine device is formed by a lamp base, a thermally conductive block, an LED lamp panel, a lens module and a fixing ring. The lamp base has a positioning opening, and after the LED lamp panel is installed to the thermally conductive block, the thermally conductive block may be embedded into the positioning opening, such that the thermally conductive block is exposed from the lamp base, and the heat generated by the LED lamp panel is conducted to the bottom of the lamp base by the thermally conductive block and dispersed in air to achieve the heat dissipation effect, and the thermally conductive block may be made of a material with a thermal conductivity corresponsive to the power of the LED lamp panel, so as to improve the heat dissipation effect.

Abstract: A multimedia disk box has a housing and a chip used to input, output, and save a signal such as speech or multimedia data. In addition to the function of holding a multimedia disk, the multi-media disk box provides other functions of added value, including recording, playing, and providing encryption/decryption.

Abstract: “A portable MP3 player has two operation modes. In a first mode, the portable MP3 player operates independently. A controller in the MP3 player reads first MP3 files from internal memory and a MP3 decoder is utilized for decoding the MP3 files. In addition, the audio data are output to an earphone or a speaker. In a second mode, a ducking station is provided for placing the portable MP3 player, which has an extended memory device, e.g. CD-ROM, for storing second MP3 files. The controller of the portable MP3 player accesses the second MP3 files via interfaces that are connected when the portable MP3 player is placed on the ducking station. The MP3 decoder of the portable player is also utilized to decode the second MP3 files and the corresponding audio data are output through the ducking station.

Abstract: The present invention discloses an MP3 player with large storage. In the proposed MP3 player, a traditional MP3 player is located on a ducking station, wherein the ducking station is provided with a power supply. The traditional MP3 reads audio data from the ducking station through the interface between them, and then decodes the audio data and feeds them into an audio signal generator. The output of the audio signal generator is fed to an earphone or a speaker. When the MP3 player is programmed, the interface of the traditional MP3 player is locked and bypassed to the interface of the ducking station. Similarly, when the MP3 player plays, the output of the audio signal generator in the traditional MP3 player is locked, and bypassed to the earphone or the speaker of the ducking station.
