IPC 7 English version
Class G10

SECTION G – PHYSICS

G 10MUSICAL INSTRUMENTS; ACOUSTICS

Notes

(1)This class covers all sound-emitting devices, in general, whether or not they may be considered as being musical.

(2)In this class, the following expression is used with the meaning indicated:

 –"musical instrument" does not exclude devices emitting a single sound signal.

(3)The following Class Index is given in place of subclass indexes, to show the grouping of the elaborations belonging to different subclasses, under the following three fundamental types:

 –wind instruments;

 –string instruments;

 –percussion instruments,

 which relate clearly to the majority of instruments.

(4)There are of course some instruments of which the principle of operation belongs less clearly to one of the three types mentioned in Note (3). They correspond to groups G10D 17/00 or G10K 7/00, G10K 9/00 or G10K 15/04, all the other groups normally finding a definite place.
