Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone with a karaoke function.
[0002]
[Prior art]
FIG. 4 is a block diagram showing a conventional mobile phone described in, for example, Japanese Patent Application Laid-Open No. 11-112615. In FIG. 4, 31 is an input unit for inputting music data composed of beat, tempo, and scale data, 32 Is a display unit that displays various data, 33 is a storage unit that stores various data, 34 is a call control unit that receives the voice of the other party, 35 is a temporary storage unit that temporarily stores scale data, and 36 generates an audio signal. A sound source generating unit 37, a mixer for synthesizing the voice of the other party with the audio signal, and a speaker 38 for outputting the voice.
[0003]
Music data composed of beat, tempo, and scale data is input by the input unit 31 and displayed on the display unit 32 and stored in the storage unit 33. After that, the scale data is read from the storage unit 33 by the operation of the input unit 31 at a speed matching the tempo of the music data to be played, and temporarily stored in the temporary storage unit 35. The sound source generator 36 reads the scale data from the temporary storage 35, converts it into an audio signal, and outputs it to the mixer 37. In addition, the call control unit 34 receives the other party's voice and outputs it to the mixer 37. The mixer 37 synthesizes the voice of the other party and the audio signal, and outputs the synthesized voice from the speaker 38.
[0004]
[Problems to be solved by the invention]
Since the conventional mobile phone is configured as described above, for the purpose of BGM with respect to the voice of the other party, the voice of the other party and the audio signal are synthesized. It does not superimpose voice and melody.
Also, in mobile phones, there is a side path that outputs its own voice to the receiver as it is. However, such a side path reduces the volume of the side path so that it does not interfere with the other party's voice during a call. In addition, since the function is used only during a call, the volume level is fixed. Therefore, in order to perform karaoke, a volume level that allows recognition of one's own voice is required, and the volume is insufficient.
Further, since a side sound path during a call is also required as in the past, it is necessary to change the side sound level during a call and during karaoke, but there is a problem that it cannot be changed by a conventional circuit.
[0005]
The present invention has been made to solve the above-described problems, and an object thereof is to obtain a mobile phone with a karaoke function.
