Description
Technical Field
[0001] The utility model relates to the technical field of tuners, in particular to a novel Huobusi tuner. Background Art
[0002] Huobusi (pinyin: huǒbùsī) is a Mongolian plucked string instrument. The traditional Huobusi is shaped like a rice spoon, with a long neck and a small resonance box. Because the sound box is covered with a membrane, the tone is full of grassland flavor.
[0003] Traditional Huobusi tuners measure the vibration frequency by picking up sound wave signals, which are easily interfered by the environment. When tuning in a noisy environment, due to the presence of multiple sound sources, while the traditional Huobusi tuner picks up the vibration sound waves of the tuned strings, other interfering sound waves will also be picked up by the Huobusi tuner. This interference will greatly reduce the accuracy of the Huobusi tuner in measuring the string frequency. In serious cases, it may even be impossible to detect and the tuner cannot be used for tuning. Therefore, a new Huobusi tuner is needed to improve the above problems. Utility Model Content
