State compression sensor component 1 to be made up of 88 compression sensors, the compression sensor component 1 is connected on bus circuit plate 2,
The bus circuit plate 2 is connected to data processing equipment 3 by Electric Wires ＆ Cables 6, and the data processing equipment 3 is responsible for processing pressing
The signal of sensor cluster 1, the power supply 5 is responsible for the power supply of whole detection means.
It is illustrated in figure 1 compression sensor component 1 and is arranged on the upper surface of piano key body 7, the size shape of compression sensor
Shape is basically identical and more slightly smaller with the size of piano key body 7, is so conducive to installing laminating.
More specifically, the compression sensor can be single soft-touch type thin film switch.
More specifically, the compression sensor can be single thin-film pressure sensor.
More specifically, bus circuit plate 2 is used to connect each compression sensor and data processing equipment 3, using connecting wire
Or flexible PCB, it is provided with the electric interfaces being connected with each part.
More specifically, data processing equipment 3 includes sensor signal conditioning circuit and processor circuit, it is responsible for pass in real time
Various kinds of sensors signal is converted into corresponding data message in sensor arrangement, is then in real time sent data by communicator 4
To the application software customized in external equipment, data of the application software as needed further to collecting are made relevant treatment and are answered
With.
More specifically, also including communicator 4, the communicator 4 is adopted and wirelessly or non-wirelessly communicated, the communicator
4 can be the functional module being integrated in data processing equipment 3, it is also possible to used as individual components, and connect with data processing equipment 3
It is logical.
More specifically, the power supply 5 is general dry battery or rechargeable batteries or external power supply, it is responsible for whole
Device provides reliable and stable working power.
With reference to Fig. 2, Fig. 3, second and the 3rd specific embodiment of the present utility model are described in detail, but not to this practicality
New claim does any restriction.
As shown in Figure 2 and Figure 3, compression sensor component 1 is arranged on the lower section of piano key body 7, according to industry standard file
Piano composition element size and shape specified in QB/T 2444-2010, in order to be able to allow cotter pilotage part 10 to be normally embedded steel
In key body 7, so the shape of compression sensor is an annulus, size dimension is identical with washer part 9.
As shown in figure 3, second specific embodiment is arranged on the lower section of piano key body 7 for the compression sensor component 1,
The lower section of the piano key body 7 is specially the lower surface of piano key body 7 and (illustrates the shadow part of the lower surface of piano key body 7
Point)；3rd specific embodiment is that the compression sensor component 1 is arranged on the front part 8 of the lower section of piano key body 7
(illustrating the dash area of the upper surface of front part 8), with the accuracy in pitch of real-time detection piano playing.
More specifically, the compression sensor can be single soft-touch type thin film switch.
More specifically, the compression sensor can be single thin-film pressure sensor.
More specifically, the compression sensor can be made up of multiple soft-touch type thin film switches.
Different according to the function that the installation site difference and needs of compression sensor are realized, compression sensor is divided into three kinds
Type：
If it is which piano key is pressed the 1, to only need to detection, only needs to single soft-touch type thin film switch and constitute i.e.
Can, now compression sensor may be installed under the upper surface of piano key body 7 or the lower surface of piano key body 7 or piano key body 7
On the front part 8 of side；
If the 2, also needing to know pressing dynamics while confirming which piano key is pressed, needing will be single light
Touch thin film switch changes single thin-film pressure sensor into, and now compression sensor may be installed the upper surface of piano key body 7
Or on the front part 8 of the lower surface of piano key body 7 or the lower section of piano key body 7；
3rd, cannot inspecting force and thin-film pressure sensor is expensive asks in view of single soft-touch type thin film switch
Topic, this utility model have also been devised another replacement scheme, i.e., replace single soft-touch type thin with multiple soft-touch type thin film switches
Membrane switch or single thin-film pressure sensor, realizing can detect pressing dynamics, while price is again suitable, it is adaptable to big rule
Mould is produced.Lever principle is met based on the motion of piano key, so piano key body 7 exists and certain inclines when piano key is pressed
Rake angle.Using this angle of inclination, by the of different sizes and piano key body 7 of piano playing dynamics and the stress of washer part 9
Afterwards the of different sizes of contact area is corresponded, and the little then contact area of dynamics is little, conversely, great efforts then contact area is big.
Using this simple corresponding relation, single soft-touch type thin film switch or single thin-film pressure sensor can be changed into many
Individual soft-touch type thin film switch, the thin film switch quantity that piano key body 7 is pressed when little with the contact area of washer part 9
It is just few, conversely, the thin film switch quantity being pressed when contact area is big is just more.Although this mode can not be detected continuously
The dynamics value of property, but the dynamics value that the cooperation of software algorithm detects segmentation is can be by, both realize piano playing dynamics
The detection of grade, while and greatly reducing production cost.Now compression sensor may be installed the lower surface of piano key body 7 or
On the front part 8 of the lower section of piano key body 7.
In sum, piano playing accuracy in pitch detection means of the present utility model, can be with by arranging compression sensor component
The dynamics order of magnitude which key is pressed and presses when detecting piano playing, by data processing equipment to sensor
Component carries out data collection and analysis process, and accuracy in pitch during piano playing can be accurately identified.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and not
The technical scheme being limited to described by this utility model embodiment, it will be understood by those within the art that, without departing from
In the case of the spirit and scope that claim is limited, this utility model can be modified or equivalent, to reach
Identical technique effect, but all within protection domain of the present utility model.
