Description
Technical Field
The present invention relates to a USB (universal serial bus) type earphone converter for a smart phone, and more particularly, to a USB type earphone converter for a smart phone, which can combine a sound source that can be played by the smart phone with a microphone sound of an earphone, and play the sound source through the connected earphone, so that it can feel as if singing in a song hall.
Background
Recently, the smart phones, which have been popularized in a large number of years, have been increasingly diversified in functions and utilization rate so as to be able to easily use DMB (digital multimedia broadcasting), music, video, movies, games, and the mobile internet, beyond the level of a simple telephone set that only performs a telephone call.
In order to listen to music, the smartphone 1 is used by connecting an earphone 2, as shown in fig. 1. The earphone (earphone)2 is composed of a speaker unit 3 to be inserted into the ear of the user and a cable 4 for connecting the speaker unit 3, and an earphone plug 6 for connecting to the smartphone 1 is provided at one end of the cable 4.
Therefore, the headphone plug 6 is connected to the smartphone 1, and music stored or played in the smartphone 10 is listened to through the speaker unit 3 of the headphone 2.
On the other hand, in the periphery of our living space today, a song hall (song hall operating place) can be easily found, and such a song hall is deeply bored in the mind of the morning. In such a concert hall, there are basically provided a song accompaniment system which provides accompaniment of a corresponding song if a user selects a desired song, a microphone for the user and accompanying the song, and a speaker system for outputting sounds collected through the microphone. Such a singing hall system is now widely spread not only in business places but also in ordinary households. In addition, in such a song hall system, a portable song accompanist has also been highlighted in consideration of portability and mobility.
However, the case of singing using the song hall system as described above is premised on the case of a person who receives the singing by other people in the periphery or the case of a song that can be freely singed in each room of the song hall, and for example, when a user walks on the street or during an electric train or bus, or is in a building, it is difficult to sing the song as if the user were free to sing the song in the song hall. This is because, even if the user sings his or her song due to a good mood or a depression, the singing voice becomes a noise nuisance to others. In addition, this is because, even if it is not a noise nuisance, the surrounding person regards the person singing as a mentally abnormal person.
Therefore, if there is an apparatus or means for minimizing noise pollution to others in the vicinity and freely singing a song at any time and place when the person wants to sing the song, the present invention can be usefully applied to various people who like going to a song hall at ordinary times, people who study vocal music specially, people who want to become singers, and the like, and the present invention has been developed by the inventor.
