Description

Microphone type music accompaniment apparatus having function for playing music video and contents}

The present invention relates to a microphone-type song group cycle having a music video and learning content playback function, and more specifically, a music file capable of playing a large-capacity music video by receiving a large video file using an external memory card or an external hard disk. The present invention relates to a microphone-type singing cycle having video and learning content playback functions.

In general, a music accompaniment apparatus is a device that allows a user to sing along by playing back an accompaniment recorded on a recording medium to a user. Such song cycles are typically used in conjunction with a video system that displays video or subtitles that change with the progress of the song in order to provide a better presence. In addition, the user is provided with a score evaluation device that evaluates the degree of volume, beat status, etc. according to the user's song so that the user can objectively know his singing ability.

There is a microphone-type karaoke cycle in which a song accompaniment function is built in the microphone, and a song accompaniment function is performed by connecting to a display device such as a TV in a wired or wireless manner. Such a microphone-type karaoke cycle has the advantage of not needing a separate device by embedding a configuration that can simultaneously output images, subtitles, accompaniment signals in the microphone body. In addition, the microphone type karaoke cycle has been used a lot because of the advantage that it can be conveniently used in the home or outdoors, not a place prepared in advance, such as karaoke.

However, such song cycles have no choice but to output only images or accompaniment signals stored in memory. In particular, in the case of a video file including a music video, there is a limit to store a large number in the memory provided in the song half cycle because of the large capacity. In addition, it is inconvenient that it is difficult for a user to reproduce various videos or accompaniment signals, including a video, a music video, and an MP3 file, which are produced by the user. In addition, since most of the learning content is provided in a large capacity, there is an inconvenience in the case of using the conventional song class cycle as a portable learner.

Accordingly, an object of the present invention is to provide a music video having a music video playback function and a microphone-type song half cycle having a learning content playback function capable of overcoming the above problems.

It is another object of the present invention to provide a microphone-type karaoke cycle having a music video and learning content playback function capable of playing various types of video or audio.

Additionally, the memory unit 140 and the wired / wireless output unit 130 may be provided.

The voice input unit 180 receives a user's voice and converts it into an electrical signal. Originally a microphone feature.

The command input unit 170 includes a plurality of input buttons 172 on the outside, and displays the selective menus on an external display device (not shown) connected to the microphone-type karaoke period by wire or wirelessly by the input buttons. And a command for selecting and controlling the displayed optional menus is input.

The command input unit 170 includes input buttons for inputting various commands for controlling the singing cycle period 100. For example, as shown in FIG. 3, only a few buttons that are essentially required, such as a menu button (MENU), a shandong button (+/-), a select button (SEL), and a play button (play / stop), are used. It can be provided. The power on / off button (173 of FIG. 2) may be separately provided, and any one of a menu button (MENU), a shandong button (+/-), a selection button (SEL), and a play button (play / stop) may be used. Long or short press can replace the power on / off button.

The menu button MENU sequentially stores a plurality of song title lists corresponding to a plurality of song files, a title list of learning contents corresponding to the learning contents, and a sound control list related to volume or sound effects through the external display device. Button to display. As an example, FIG. 4 shows a list of learning content titles. 5 illustrates the sound control list.

The Shanghai East button (+/-) is selected from the song title list and the learning content title list displayed through the menu button (MENU), the desired song title or learning content title, or volume and sound effects related sound control This button is used to move up and down the list to select the desired sound control menu from the menu list.

For example, the learning content title list of FIG. 4 moves up and down to any one learning content title. For example, you can move to Chapter 2.

The selection button SEL is any one of the song titles that are moved through the Shanghai Dong button (+/-) of the song title list, the learning content title list, or the sound control list displayed through the menu button MENU. This button is used to select a learning content title or a sound control menu. For example, select the menu ('Chapter2') moved by the Shanghai East button (+/-).

The play button (play / stop) is a button for controlling play, stop, pause, etc. of a song or learning content corresponding to the selected song title or learning content title. In another embodiment, the selection button SEL and the play button stop / play may be integrated into one button. In this case, it will have a structure that is directly reproduced by selection.
