【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Music from a predetermined sound source is input to the graphic equalizer 2 via an amplifier, amplified by the power amplifier 7 and output from the speaker 9. The voice from the microphone is also input to the digital echo circuit 4 via the amplifier, delayed for a predetermined time, and output from the speaker 9 via the power amplifier 7 along with the music via the microphone sound quality circuit 3. ing. In this embodiment, a super bass function is provided, and the output from the graphic equalizer 2 is input to the low pass filter 5 via the super bass on / off switch 12 and amplified by the power amplifier 6 for low frequency amplification to produce a super bass speaker. The low frequency range is output from 8.

The graphic equalizer 2 is controlled by the microcomputer 1, and in response to a command from the sound quality character switch 10, the types of KARAOKE songs such as “enka” and “pops”, “movies” when watching a movie, and music. You can select "Music" mode for listening to music and "Night" mode for listening to music at night. The selected mode is displayed on the sound quality character LED 11. The microcomputer 1 is configured to send data to the graphic equalizer 2 corresponding to each mode and set the frequency characteristics shown in FIG.

The microphone sound quality circuit 3 is also controlled by the microcomputer 1, and the micro computer 1 switches the microphone sound quality circuit 3 in accordance with each mode to set the frequency characteristic shown in FIG. ing.

The microcomputer 1 further controls the digital echo circuit 4, and the delay time is set as follows in correspondence with each mode. "Enka" "Pop" "Movie" "Music" "Night" …………………………………………………………………………………………………… Delay time 200ms 150ms 200ms 200ms 200ms

In this embodiment, the super bus on / off switch 12 is further controlled by the microcomputer 1, and the super bus on / off switch 12 is turned off at the time of “night”. .

The operation will be described with reference to FIG. The operation content of the sound quality character switch 10 is read (step 40), it is determined whether or not the mode is different from the present mode (step 41), and if the mode is different, the sound quality character LED 11 is cleared (step 42), and "night" is selected. It is determined whether the mode is set (step 43). In the case of the "night" mode, the super bus on / off switch 12 is turned off and the mute is turned on (steps 45 and 47). If it is not the "night" mode, it is judged whether or not it is the super bus mode (step 44), and if it is the super bus mode, the super bus on / off switch 12 is turned on (step 46).

When the mute is turned on, the sound quality character mode is determined (step 48). In the case of "Enka", the sound quality character LED 11 is set to "Enka" (step 49), the graphic equalizer 2 is controlled to set the frequency characteristic of "Enka" (step 50), and the microphone sound quality circuit 3 is set to " The frequency characteristic of "enka" is set (step 51), and the delay time of the digital echo circuit 4 is set to 200 ms (step 64). Finally, the mute is turned off and the process ends (step 56).

In the case of “pops”, the sound quality character LED 11 is set to “pops” (step 52), and the graphic equalizer 2 is controlled to set the frequency characteristics of “pops” (step 53). Is set to the "pops" frequency characteristic (step 54), and the delay time of the digital echo circuit 4 is set to 150 ms (step 55). Finally, the mute is turned off and the process ends (step 56).

In the case of “movie”, the sound quality character LED 11 is set to “movie” (step 57) and the graphic equalizer 2 is controlled to set the frequency characteristic of “movie” (step 58). 3 is set to normal (step 63), and the delay time of the digital echo circuit 4 is set to 200 ms (step 64). Finally, the mute is turned off and the process ends (step 56).

In the case of "music", the sound quality character LED 11 is set to "music" (step 59), and the graphic equalizer 2 is controlled to set the frequency characteristic of "music" (step 60). 3 is set to normal (step 63), and the delay time of the digital echo circuit 4 is set to 200 ms (step 64). Finally, the mute is turned off and the process ends (step 56).

In the case of “night”, the sound quality character LED 11 is set to “night” (step 61), the graphic equalizer 2 is controlled to set the frequency characteristic of “night” (step 62), and the microphone sound quality circuit 3 Is set to normal (step 63), and the delay time of the digital echo circuit 4 is set to 200 ms (step 64). Finally, the mute is turned off and the process ends (step 56).
