发明名称 Ocarina
摘要 An improved ocarina for providing improved tonal quality with better maintenance of said tonal quality. Ocarinas are generally oval in shape with finger holes on one side and thumb holes on the other side of the ocarina, with a windway and a sound hole called a “voicing”. A user blows into the voicing, creating a tone which varies depending on whether the fingers and thumbs are over the finger holes or thumb holes. Partitions are placed inside of said ocarina between said thumb hole and said sound hole which are customarily located on the same side of the ocarina. Partitions are located close to the thumb holes and distal from the sound hole. In the improved ocarina, a user may open the thumb hole without significant loss of tonal quality, unlike a standard ocarina where opening of the thumb holes ordinarily results in a decreased tonal quality.
