MUSICAL INSTRUMENTS; ACOUSTICS
 G10

Note(s)

  1. This class covers generally all sound-emitting devices, whether or not they may be considered as being musical.
  2. The term "musical instrument", used in this class, should not be understood as excluding devices emitting a single sound signal.
  3. For the convenience of users, the following Class Index is given in place of Sub-class Indexes, to show the grouping of the elaborations belonging to different sub-classes, under the 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 these three types. They correspond to groups G10D 17/00 and G10K 7/00, G10K 9/00, G10K 10/00, 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 and reproducing G11B; associated working with recording or reproducing apparatus G11B 31/02)
 G10F

Note(s)

Aspects of musical instruments which are independent of the automatic actuation are covered by the relevant sub-classes G10B, G10C, 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 sub-class deals with 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 sub-class, 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 sub-class covers also the production of sounds which may not be audible to human beings but which are audible to animals.


 G10L
ANALYSIS OR SYNTHESIS OF SOUND WAVES; RECORDING WAVE-FORMS OF SOUND WAVES, e.g. SPEECH (measurement of mechanical vibrations G01H, e.g. G01H 3/08; electrophonic musical instruments G10H)
