A portable electronic device includes a housing, a substrate, a radiation conductor and a short circuit conductor. The housing defines an accommodating space and includes a frame that has a body portion and a radiation portion. The substrate is disposed in the accommodating space, is surrounded by the frame, and has a grounding portion. The radiation conductor is disposed in the accommodating space, is electrically coupled to the radiation portion, and includes a feed-in point. The short circuit conductor is electrically coupled between one end of the radiation portion and the grounding portion.

Portable electronic device

A structure for playing MIDI messages including a main-control element, a buffer memory, a MIDI synthesizer, and a pre-processor is provided. The main-control element receives tone colors and the MIDI messages, and loads at least part of the tone colors to the buffer memory. The main-control element transmits the MIDI messages to the pre-processor. The pre-processor coupled to the main-control element and the buffer memory, is used for analyzing the MIDI messages. In addition, the pre-processor dynamically determines at least part of the tone colors to be saved in the buffer memory based on the capacity of the buffer memory.
