Abstract
The utility model discloses an electric device which connects a piano to a computer, the electric device comprises a sensor and a microcontroller, wherein the sensor comprises contact switches and key-press switch interfaces, the quantity of the contact switches and the key-press switch interfaces is the same with that of the keyboard of the piano, and the contact switches and the key-press switch interfaces can be mounted on the piano body, the contact switches are used to monitor the state of the key-presses of the piano and generate relative electrical signals, the microcontroller is formed by a main chip and a communication module, wherein the main chip is used to identify the electrical signals of the state of the key-presses of the piano, and the communication module is used to transmit data, the microcontroller is connected with the sensor, and the microcontroller can be connected with an external computer. The electric device can be obtained just needing to simply remodel a traditional common piano, and then, users can apply high-speed processing and real-time monitoring performance of computers to the creation and study of pianoforte music. Further, the electric device is simple in realizing mode and low in cost.
Description
Technical field
The utility model relates to computer peripheral, specifically is a kind of electronic installation that piano is connected with computing machine.
Background technology
Existing keyboard instrument comprises piano, mellotron, fender, midi keyboard.Piano is to knock string by the mechanical motion of key by gear train to produce vibration and sounding.Mellotron, fender, midi keyboard are to trigger electronic switch by key to produce electric signal via chip or Computer Processing, again by electronics software and hardware system sounding (being commonly called as " electroacoustic ").Piano is a kind of ancient musical instrument, though mellotron, fender, midi keyboard occur for many years, fails to shake the market position of piano always.Reason mainly is that the sense of touch of piano key is that electrophonic musical instrument is difficult to imitate, and the abundant musical expression that piano had also is that electrophonic musical instrument is difficult to substitute.But mellotron, fender, midi keyboard also have the unexistent function of a lot of pianos, particularly can connect computing machine, make that musician or music scholar can be with the high speed processing of computing machine, and the performance of monitoring applies in the creation and study of music in real time.
How combining both are simple and effective, that is, the advantage that mellotron, fender, midi keyboard can link to each other with computing machine is transplanted on traditional piano, is that technical matters to be solved is arranged.
The utility model content
For overcoming the problems referred to above, fundamental purpose of the present utility model provides the easy electronic installation that common piano and computing machine are coupled together of a kind of energy, so that common piano has the function of mellotron, fender, midi keyboard when keeping traditional advantage.
For solving above technical matters, a kind of electronic installation that piano is connected with computing machine of the present utility model comprises sensor and single-chip microcomputer, wherein: sensor comprises the contact switch and the keyswitch interface of the be installed on piano body suitable with fingerboard quantity, and described contact switch is used to monitor the state of key and produces corresponding electric signal; Single-chip microcomputer is made up of the communication module that is used to identify the master chip of key state electric signal and be used for Data transmission, and described single-chip microcomputer links to each other with sensor; This single-chip microcomputer can be connected with outer computer.
As a kind of improvement, a kind of electronic installation that piano is connected with computing machine of the present utility model can also comprise the light emitting diode of the inserted piano body suitable with fingerboard quantity, and described light emitting diode is connected to single-chip microcomputer.
As further improvement, above-mentioned light emitting diode is double color luminotron.
Adopt device provided by the utility model with common piano with after computing machine is connected, the key information that the user can be played is passed to computing machine, for computer programs process.The utility model only needs the common piano of tradition is simply reequiped, and musician or music scholar just can be with the high speed processing of computing machine, and the performance of monitoring applies in the creation and study of piano music in real time, and implementation is simple, and is with low cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural principle synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of electronic installation that piano is connected with computing machine of the present utility model mainly comprises sensor and single-chip microcomputer, wherein: sensor comprises the contact switch and the keyswitch interface of the be installed on piano body suitable with fingerboard quantity, described contact switch is used to monitor the state of key and produces corresponding key state electric signal, and is connected to single-chip microcomputer by the keyswitch interface; Single-chip microcomputer is made up of master chip that is used to identify key state electric signal and the communication module that is used for Data transmission, and its effect is analysis from the electric signal of sensor and sends to outer computer, for computer programs process.
In addition, in this embodiment, the light emitting diode that also comprises the inserted piano body suitable with fingerboard quantity, described light emitting diode is connected to single-chip microcomputer, like this, computing machine can send signal, passes to single-chip microcomputer, light corresponding color and play suggesting effect thereby handle the corresponding light emitting diode of relief, for example misdirection etc. through single-chip microcomputer.
In the present embodiment, light emitting diode is double-colored.Double-colored effect is that the prompting player is with the left hand or the right hand.
In fact, can also adopt other device to replace light emitting diode, also can for three looks or more polychrome point out more information, these conspicuous conversion all fall into protection domain of the present utility model.
Claims (3)
