MUSICAL INSTRUMENTS; ACOUSTICS
 G10

Note(s)

  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.
 G10B
ORGANS; HARMONIUMS (mouth organs or accordions G10D; aspects of automatic actuation G10F; combinations of microphones, pick-ups or amplifiers with musical instruments, electronic organs G10H)

 G10C
PIANOS (non-musical aspects of toy pianos A63H 5/00; aspects of automatic actuation G10F; combinations of microphones, pick-ups or amplifiers with musical instruments G10H)

 G10D
MUSICAL INSTRUMENTS NOT OTHERWISE PROVIDED FOR (aspects of automatic actuation G10F; combinations of microphones, pick-ups or amplifiers with musical instruments G10H; sound-producing devices not regarded as musical instruments or parts thereof G10K)

 G10F
AUTOMATIC MUSICAL INSTRUMENTS (non-musical aspects of toy instruments A63H 5/00; sound-recording or reproducing G11B; associated working with recording or reproducing apparatus G11B 31/02)
 G10F

Note(s)

This subclass does not cover aspects of musical instruments which are independent of the automatic actuation, which are covered by subclass G10B, G10C or G10D.


 G10G
AIDS FOR MUSIC (metronomes G04F 5/02; teaching music G09B 15/00)

 G10H
ELECTROPHONIC MUSICAL INSTRUMENTS (electronic circuits in general H03)
 G10H

Note(s)

This subclass covers musical instruments in which individual notes are constituted as electric oscillations under the control of a performer and the oscillations are converted to sound-vibrations by a loud-speaker or equivalent instrument.


 G10K
SOUND-PRODUCING DEVICES (sound-producing toys A63H 5/00; musical instruments or parts thereof, see the relevant subclass, e.g. G10D); ACOUSTICS NOT OTHERWISE PROVIDED FOR (generating or transmitting mechanical vibrations of infrasonic, sonic or ultrasonic frequency for performing mechanical work B06B; direction-finding, locating, distance or velocity measuring by means of infrasonic, sonic or ultrasonic waves G01S; generating seismic energy G01V 1/02; signalling or calling arrangements, alarm arrangements G08B; electromechanical transducers H01L, H04R; transmission systems using infrasonic, sonic, or ultrasonic waves H04B 11/00)
 G10K

Note(s)

This subclass covers also the production of sounds which may not be audible to human beings but which are audible to animals.


 G10L
SPEECH ANALYSIS OR SYNTHESIS; SPEECH RECOGNITION (measurement of sound waves in general G01H; frequency spectrum analysis of electric signals in general G01R 23/16; electrophonic musical instruments G10H; sound-producing devices other than musical instruments G10K; information storage, e.g. sound storage, G11; coding, decoding or code conversion, in general H03M)
