* This invention is designed for MP3 player with low sound vibration conversion function and LED character display.

More specifically, when listening to music using an MP3 player,

You can listen to music with your ears, and at the same time have instruments such as drums and drums

Detects frequencies below 300Hz, analyzes them, converts them into vibrations,

You can feel it, and the LED character display device allows the user to listen to music

The present invention relates to a device that enables various productions.

In general, MP3 player is easy to carry (size, weight) and reduces power consumption.

Have been developed with focus, or technology has advanced, on the other hand

It is installed in various mobile devices (e.g. mobile phone, PDA, PMP, etc.)

It is true that only role could be played.

Especially for small music players like MP3 players, large audio

Hyun-hyeon had the disadvantage of not expressing the thrill of the bass at all.

In terms of audio theory, the lower the frequency of the sound,

The loudspeakers must be large and the sound in this frequency band has no directivity.

To refer to the expression of feeling in the body rather than listening.

The bass portion of the audio is quite important.

So a speaker that is in the range below 300Hz is called a super woofer

In terms of power and power, it is different from existing small speakers.

Therefore, up to now, large-scale audio is not available in small music player.

It seems almost impossible to express the thrill of losing bass

It is true.

In an effort to make up for some of these drawbacks,

The vibration speed of the mobile phone is changed to match the level of music.

Although attempts have been made to simplify this approach,

It is estimated that due to the increase in power consumption caused by copper, it is insufficient in terms of effectiveness.

I am getting it.

Also, I want to express my personality even on small devices like MP3 players.

The need for a product that meets the expectations of the younger generation

It is recognized as part of the item.

Therefore, the present invention is a low-frequency drive signal of less than 300Hz to the MP3 player

And then the solenoid is driven to vibrate the bass

In addition to the function to deliver to the information and the MP3 file currently being played

Sentence, emoticon, icon, equalizer, current time, stop

Device including LED character display device that can display various information such as watch

To provide.
