The present invention relates to a mobile communication terminal (mobile communication terminal), in particular to provide a mobile communication terminal of the speaker device which is provided in the mobile communication terminal by providing a complex opening and closing method of a combination of a folding type opening and closing type opening and closing method By eliminating the restrictions and providing a speaker device having a higher capacity, it is possible to prevent a decrease in the output of the voice signal due to the limitation of the installation space, and by providing a high capacity speaker device having a larger output capacity in the installation space of the expanded speaker device. The present invention relates to a mobile communication terminal having a high-capacity speaker device capable of providing a speaker device having a richer tone without additional structures or devices for improving sound quality.

In general, a mobile communication terminal is a wireless communication device that allows a user to carry a voice call with a specific person, and transmits a call message including a unique number of a receiver mobile communication terminal through a base station call channel to call a specific mobile communication terminal. After that, when a response is received from the mobile communication terminal, the system is configured to enable a call between the sender and the receiver.

The above-described mobile communication terminal is composed of a system for enabling a call between a sender and a receiver when a response is received from the mobile communication terminal after transmitting a call message including a unique number of the other mobile communication terminal through a base station call channel. It is.

However, due to the rapid development of the electronic and telecommunications industry, the mobile communication terminal is not only a simple voice call, which is the main function of the above-described conventional mobile communication terminal, but also a game and a video on demand, an electronic dictionary, an MP3 player, a photo, and the like. The latest functions such as video shooting and TV watching are being added.

In order to use the latest functions as described above, in the conventional mobile communication terminal, the image display unit outputs the image signal output when the above-described various functions are implemented, and the audio signal accompanying the various functions is implemented. A speaker device is provided, and the type of the conventional mobile communication terminal and the form having an image display unit and a data input unit will be described with reference to FIG. 1.
