In this specification, the terms "comprising ", or" comprising "and the like should not be construed as necessarily including the various elements or steps described in the specification, Or may be further comprised of additional components or steps. Also, the terms "part," " module, "and the like described in the specification mean units for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram schematically illustrating an internal configuration of a song half-pitcher according to an embodiment of the present invention, and FIG. 2 is a view for explaining pitch correction according to an embodiment of the present invention.

1 is a block diagram of a music playing apparatus 100 according to an embodiment of the present invention. The music playing apparatus 100 includes a microphone 110, a speaker 115, an input unit 120, a display unit 125, a signal processing unit 130, a memory 135 And a processor 140. As shown in FIG.

The microphone 110 is a means for receiving a voice signal.

That is, the microphone 110 according to an embodiment of the present invention may perform a function of an input device for inputting a control command to the song counter 100 instead of simply receiving a voice signal. For this, the microphone 110 according to an embodiment of the present invention may include a plurality of key buttons for key value setting, chord mode, and chord interval selection for pitch adjustment.

In another example, a key value for pitch control may be set according to the direction in which a certain area of the microphone 110 is rotated and the number of rotations. For example, when a part of the microphone 110 is rotated in the first direction, a pitch adjustment command according to the pitch key up may be generated. A key value for key-up may be set according to the number of rotations in the first direction. That is, when one rotation is made in the first direction, the pitch adjustment command including the key setting value may be generated so that one key is raised. On the other hand, when a part of the microphone 110 rotates in the second direction, a pitch adjustment command according to the pitch key down may be generated. Likewise, the key setting value can be set according to the number of rotations in the second direction.

The speaker 115 is a means for outputting a sound signal.

The input unit 120 is a means for receiving a user's control command.

The input unit 120 may receive a control command from the remote controller or the microphone 110 and output the control command to the signal processing unit 130 or the processor 140.

The display unit 125 is a unit for outputting data input to the song half-player 100 or data stored in the song half-player 100 in the form of time information.

For example, the display unit 125 may be a liquid crystal display.

The signal processing unit 130 is means for adjusting the pitch of a voice signal inputted through the microphone 110 according to a pitch adjustment command inputted through the microphone 110. [

In the present specification, a pitch control command is input through the microphone 110 in order to facilitate understanding and explanation. However, it is needless to say that the pitch control command may be inputted through a remote controller in addition to the microphone.

For example, the signal processing unit 130 may up-down or down-down a voice signal inputted through the microphone 110 according to a pitch control command and output it to the processor 140 or the speaker 115 . At this time, the key value of the voice can be up or down according to the key setting value included in the pitch control command at the time of key-up or key-down.

In addition, the signal processor 130 converts (adjusts) the pitch of the voice signal according to the pitch control command, converts the analog voice signal input through the microphone 110 into MIDI data can do. Then, the signal processor 130 may correct the pitch of the voice signal converted into the MIDI data according to the key setting value included in the pitch control command. At this time, the signal processor 130 may correct the pitch of the voice signal based on the reference pitch of the accompaniment data.

Further, in correcting the pitch of the voice signal according to the pitch control command, the signal processing unit 130 may correct the pitch of the voice signal by further considering the accompaniment data.

Will be described in more detail with reference to FIG.

As shown in FIG. 2, it is assumed that the pitch of the accompaniment data is equal to 210, and that the key value of the user's voice signal input through the microphone 110 is equal to 215 in FIG. Here, it is assumed that the pitch control command including the key setting value according to the 2 key-up from the microphone 110 is inputted. The signal processing unit 130 may correct the pitch of the voice signal inputted through the microphone 110 so that the key value of the voice signal inputted through the microphone 110 is 2-key-up according to the pitch adjustment command.

The signal processing unit 130 basically adjusts (corrects) the pitch of the voice signal according to the key setting value included in the pitch control command in adjusting the pitch of the voice signal. When the audio signal is corrected according to the key setting value included in the voice adjustment command, the signal processing unit 130 adjusts the pitch of the accompaniment data (melody data) If the voice signal does not coincide with the pitch of the accompaniment data, the signal processor 130 determines that the user has made a voice-out while singing through the microphone or that the user has determined that the voice is a voice, Additional corrections may be made to match.

2, it can be seen that the pitch of the voice signal corrected according to the key setting value according to the second key-up in the case of the first and second notes of FIG. 2 coincides with the accompaniment data. However, referring to the third and fourth notes of FIG. 2, it can be seen that the pitch of the voice signal corrected by the key setting value according to the two key-ups does not coincide with the accompaniment data. In this case, the signal processing unit 130 may perform additional correction so that the pitch of the corrected voice signal matches the pitch of the accompaniment data.

As a result, the accompaniment data is corrected so that only the user's voice signal is up-keyed up without signal processing, which is advantageous in attracting the user who uses the karaoke machine.

In addition, when the user inputs a pitch control command corresponding to the key-up or key-down through the microphone 110, the user may set all of the keys of the voice signal input through the microphone to the entire song to be corrected, The pitch may be variably adjusted only for the interval.

For example, when the user starts the accompaniment of the song, when the user operates the microphone 110 to input a pitch control command corresponding to the key-up or key-down, the song- Can be key-up or key-down according to the key setting value included in the pitch adjustment command.

For example, when a user operates the microphone 110 to input a pitch control command while singing a song, the song pitcher 100 transmits a voice signal to a predetermined section (e.g., one word, one measure, etc.) The pitch can be keyed up or keyed down according to the key set value included in the pitch control command.

Of course, the microphone 110 may be provided with a separate key button or switch for interval selection, for example, in order to improve the convenience of selecting the interval for pitch control. Accordingly, when a separate key button or switch for selecting a section is activated in the microphone 110, the song half-pitcher 100 may adjust the pitch for the corresponding section.

The signal processing unit 130 may generate a chord corresponding to the voice signal and output the chord to the speaker 115 or the processor 140 according to a chord adjustment command input from the microphone 110. [ Here, the chord adjustment command may include at least one of a chord mode and a chord interval.

Accordingly, the signal processor 130 generates a chord according to the chord mode included in the chord control command, and outputs the chord to the speaker 115 or the processor 140. Of course, the signal processor 130 may generate a chord only for a chord interval included in the chord adjustment command. Here, the chord mode may be at least one of, for example, 3 degrees, 5 degrees, high, low, high and low.

The memory 135 is a means for storing applications, algorithms, and various data derived in this process required to perform at least one of pitch adjustment and chord adjustment of the song half-pitcher according to an embodiment of the present invention.

Processor 140 may be coupled to internal components (e.g., microphone 110, speaker 115, input 120, display portion 125, signal (s)) of song counter 100 according to an embodiment of the present invention. Processing unit 130, memory 135, and the like).

3 is a flowchart illustrating a pitch adjustment method of a song half-pitcher according to an embodiment of the present invention.

In step 310, the song pitcher 100 receives a pitch adjustment command from the microphone 110. Here, the pitch adjustment command may include a key-up or key-down control command and a key setting value. The key setting value may be a key value for key-up or key-down based on the current key.

For example, when the key-up button provided on the microphone 110 is pressed once or rotated one time in the first direction, the key setting value may be set to one. Also, when the key down button provided on the microphone 110 is pressed once or rotated one time in the second direction, the key setting value may be set to -1.

In step 315, the song pitcher 100 corrects the pitch of the voice signal input from the microphone according to the pitch adjustment command by up or down.

For example, the song pitcher 100 can adjust the pitch of a voice signal input through the microphone 110 according to a key setting value included in the pitch adjustment command. Since this is the same as that described above with reference to FIG. 1 and FIG. 2, a duplicate description will be omitted.

In step 320, the song pitcher 100 outputs the voice signal whose pitch is corrected through the speaker.

In step 325, the song halfplayer 100 determines whether a chord addition command has been input. Here, the chord addition command may include at least one of a chord mode and a chord interval.

Depending on the implementation method, the chord interval may be input through a separate control command, unlike the chord addition command.

If no chord addition command is input, the process waits at step 325.

However, if a chord addition command is input, the song pitcher 100 generates a chord according to the chord mode included in the chord addition command in step 330. In generating a chord, the song pitcher 100 can generate a chord according to the corresponding chord mode based on the user's voice signal (corrected voice signal). At this time, the song halfplayer 100 can generate a chord according to the chord mode only for the chord interval.

In step 335, the song halfplayer 100 outputs the generated chord through the speaker.
