“变调器”是改变伴奏音乐音调的设备。由于每个音域的不同,要求演唱时的伴奏音乐的音调亦不尽相同,通过变调器,可以使演唱者在合适的音域演唱。经过变调器升调的声音显得悦耳,音量似乎大了一些。这是因为频率升高后,人耳对高音较敏感的缘故;降调后显得低音丰满,音量也会略显小些。变调器是通过电子线路对音乐中的乐音频率进行升调和降调处理的。其 “Tuner” is a device that changes the pitch of accompaniment music. Due to the difference of each range, the tone of accompaniment music required when singing is also different. Through the tuner, the singer can make a concert in a suitable range. After the tune-up tone sounds sweet, the volume seems a bit larger. This is because the frequency of the human ear after the treble is more sensitive to the reason; lowered tone appears full bass, the volume will be slightly smaller. Transducer is through the electronic circuit on the music tone frequency up and down processing. its
