Abstract
Abstract A sounding note board for music instruction is disclosed, comprising conductor bars being arranged below the board surface. The bars are connected with on/off switching means, each of them being arranged to switch a separate sound generator which is assigned to one particular bar. The output terminals of all sound generators are connected with the input of a common amplifier which feeds a speaker. The switching means are designed to form proximity switches, controlled by the respective bars. The proximity switches are operable by a person touching the board surface above the particular bar. The board provided with an ordinary writing layer may comprise an iron or magnetic layer which is arranged at such a distance from the writing surface that attachable magnetic or iron platelets adhere to the writing surface.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
167 words
Sounding note board means for music instruction, comprising a plurality of tone generator means for generating predetermined sound frequencies, a board, a plurality of conductor bars positioned below a surface of the board, switching means operatively connecting said conducting bars and said tone generator means for selective actuation of the latter in accordance with selection of particular ones of said bars by a player, said conductor bars constituting portions of proximity switch means operable by a player touching the board surface at desired locations of a note pattern, whereby touching of said surface by a body portion of a player in the operating vicinity of a conductor bar causes its associated proximity switch means to be actuated causing said switching means to actuate a predetermined portion of said plurality of tone generator means, said board being provided with a writing layer and an iron or magnetic layer arranged at such a distance from the writing surface that attachable magnetic or iron platelets adhere to the writing surface.
Claim 2
Dependent Claim
167 words
Sounding note board means for music instruction, comprising a plurality of tone generator means for generating predetermined sound frequencies, a board, a plurality of conductor bars positioned below a surface of the board, switching means operatively connecting said conducting bars and said tone generator means for selective actuation of the latter in accordance with selection of particular ones of said bars by a player, said conductor bars constituting portions of proximity switch means operable by a player touching the board surface at desired locations of a note pattern, whereby touching of said surface by a body portion of a player in the operating vicinity of a conductor bar causes its associated proximity switch means to be actuated causing said switching means to actuate a predetermined portion of said plurality of tone generator means, said board being provided with a writing layer and an iron or magnetic layer arranged at such a distance from the writing surface that attachable magnetic or iron platelets adhere to the writing surface.
Claim 3
Dependent Claim
36 words
Note board means as set forth in claim 1, including an alternating voltage generator, establishing an ambient field that is coupled to the operating vicinity of said tone bars by a body portion of a player.
Claim 4
Dependent Claim
87 words
Note board means as set forth in claim 1, in which the switching means includes a section associated with each of said conductor bars, each of said sections of said switching means including at least one electronic switch connected by a bias circuit to the associated conductor bar in such a manner that the electronic switch is cut off in its idle state and opens when the board surface in the operating vicinity of the associated conductor bar is touched by a body poRtion of a player.
Claim 5
Dependent Claim
23 words
Note board means as set forth in claim 3 in which each of the electronic switches includes means for adjusting the sensitivity thereof.
Claim 6
Dependent Claim
33 words
Note board means as set forth in claim 1, also including an individual plug operatively connected in circuit at a point between each of said proximity switches and its associated tone generator means.
Claim 7
Dependent Claim
48 words
Note board means as set forth in claim 1, in which there are associated with each of said tone generator means half-tone generators which oscillate at a half-step lower and higher, respectively, than the associated tone generator means, and additional switches for selectively switching on said half-tone generators.
Claim 8
Dependent Claim
38 words
Note board means as set forth in claim 1, comprising noise generator means operatively connected to the tone generators and tone generator means which superimposes distortions on normally sinusoidal outputs of said tone generators and tone generator means.
Claim 9
Dependent Claim
26 words
Note board according to claim 1, characterized in that the iron or magnetic layer as viewed from the writing surface is arranged below the conducting bars.
Claim 10
Dependent Claim

Note board means as set forth in claim 1, in which the board includes layers in the following sequence: a. writing layer b. insulating layer c. layer bearing the conducting bars d. second insulating layer e. adhesive layer f. iron or permanently magnetized layer g. adhesive layer h. supporting layer.
Claim 11
Dependent Claim
28 words
Note board means as set forth in claim 1, in which the board is provided with staff lines formed by raised ridges on the surface of the board.
Claim 12
Dependent Claim
16 words
Note board means as set forth in claim 1, in which the attachable platelets are color-coded.
Claim 13
Dependent Claim
19 words

Claim 14
Dependent Claim
57 words
Note board means as set forth in claim 1, in which the conductor bars are vertical in the board as viewed by a player, and that there are markers associated with the conductor bars forming protrusions in front of the board surface so as to be detectable by touch by a player feeling over the board surface.
Claim 15
Dependent Claim
19 words
Note board means as set forth in claim 1, in which the board is constructed entirely of flexible material.
