Description

  The present invention relates to a two-fold type mobile phone which is particularly useful for listening to music or music media distributed in recent years even with a mobile phone which has been widely used.

  Recent mobile phones can receive TV, have a navigator function for directions, receive music, and many other functions. In addition, in the case of a two-fold mobile phone, the structure has been sufficiently considered so that the lids do not deviate from each other.

  When listening to music, a connector that can be connected to a mobile phone is inserted to listen to music via a cord. This code is very disturbing and you should avoid adopting it if possible.

However, it is popular to use chords when listening to reliable stereo. Therefore, since the characteristics of recent speakers have been remarkably improved, the present inventors have focused on whether cordless and stereo music can be enjoyed on a mobile phone.
