Is there any patent on the instrument itself?

Or is it a national cultural property?

[Intellectual Property Rights]: Erhu is a traditional musical instrument. The instrument itself belongs to existing technology, so there is no patent dispute.

But improvements to the existing erhu still exist.

For example, an applicant in Canada has obtained the corresponding patent right, which mainly improves the sound quality of the Erhu sound and increases the sound quality of the Erhu by changing the direction of the sound window at the end of the Erhu barrel to reflect the Erhu sound upward (or in other directions).

The volume allows the erhu players to hear their own performance more clearly. At the same time, in the actual performance in the concert hall, the sound window that reflects upward or in other directions directly sends the sound to the top reflector of the concert hall stage or other

Reflectors in different directions are reflected to the auditorium through reflectors on the top of the stage or reflectors in other directions, so that the audience can hear more clearly and loudly.
