Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present invention.
The percussion melody instrument emits sound by beating a beating area such as keys made of a vibrating material. Correspondingly, the design of the electronic percussion melody instrument can also simulate the sound effect of the corresponding percussion melody instrument by processing the vibration signal and the position signal at the key. In order to collect signals during performance, the electronic percussion melody instrument may be provided with various types of sensors for detecting vibration signals and position signals in a striking area (e.g., a key area) so as to simulate the sound effects of different instruments according to the detected performance signals. Specifically, by detecting the striking process of the striking area, the sensor can convert mechanical energy generated by the striking into electrical energy in the form of electrical current. Here, the magnitude of the current may be different depending on the strength of the tap. Thereafter, the controller in the electronic percussion melody instrument can determine sound source data corresponding to the struck region from the current signal, and generate and output a corresponding sound effect through the playback device.
As known to those skilled in the art, current percussion melodic instruments are of a variety of types including, for example, xylophone, tremolo, marabaphone, and chime. The number of keys of each percussion melody instrument is also different, and there are at least 6 cases in the case of maraba, but the number of keys of xylophone, tremolo, etc. is also different from that of maraba. In addition, some electronic percussion melody instruments are also provided with structures such as resonance tubes, fan blades and rotators, so that the percussion melody instrument is large in size and inconvenient to carry. In view of the foregoing, it is desirable for a player to realize a performance experience and performance sound effect of playing one of a plurality of electronic percussion melodies on one electronic percussion melody. In this way, on the one hand, the player does not need to purchase different instruments separately for playing different electronic percussion melody instruments, thereby significantly reducing the cost of the playing operation. On the other hand, since a plurality of electronic percussion melody instruments are not required, the player can set only one electronic percussion melody instrument, thereby facilitating arrangement of the instruments and significantly reducing the occupation space.
To this end, the present invention proposes an apparatus for an electronic percussion melody instrument to realize a multifunctional electronic percussion melody instrument. Specifically, the user can control the body of the electronic percussion melody instrument by using the man-machine interface in the apparatus of the invention, for example, to select the performance mode. Further, in the selected performance mode, the controller may determine sound source data corresponding to the performance signal from the received performance signal of the electronic percussion melody instrument and instruct the output device to play, thereby achieving a performance effect of one of a plurality of electronic percussion melody instruments on one electronic percussion melody instrument.
Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic view showing the composition of an apparatus 100 for an electronic percussion melody instrument according to an embodiment of the present invention.
As shown in fig. 1, the apparatus 100 may include a human-machine interface 110 and a controller 120. In one embodiment, the human-machine interface 110 may be connected to the electronic percussion melody instrument 200 so as to achieve human-machine interaction with the electronic percussion melody instrument 200. In particular, the human-machine interface 110 may include at least a mode option for selecting a performance mode of the electronic percussion melody instrument 200, and wherein different performance modes of the electronic percussion melody instrument may simulate sound effects of different percussion melody instruments. In one embodiment, the controller 120 may be configured to receive a user selection of a performance mode of the electronic percussion melody instrument via a mode option. Further, in response to a performance signal received from the electronic percussion melody instrument 200, the aforementioned controller 120 may determine sound source data corresponding to the performance signal according to a selected performance mode so as to obtain sound effects of the simulated electronic percussion melody instrument using the sound source data.
As for the above mode options, according to different application scenarios, the man-machine interface 110 of the present embodiment may be provided with a mode option for selecting the sound effect of an electronic percussion melody instrument such as a xylophone, a tremolo or a marban. Before playing, the user can select any one of the foregoing mode options as desired. Taking a marlin musical instrument as an example, when playing, the controller 120 determines the sound source data of the marlin musical instrument corresponding to the playing signal according to the playing signal received from the electronic percussion melody musical instrument 200 and the mode option of the marlin musical instrument selected by the controller, so that the subsequent electronic percussion melody musical instrument 200 can simulate the sound effect of the marlin musical instrument according to the determined sound source data. The performance signal here may include information on the strength, position, time, etc. with which the key is pressed or struck. In various application scenarios, the aforementioned performance signal may be acquired by one or more sensors arranged in an electronic percussion melody body (described later) of the present invention.
In order to connect the apparatus 100 of the present invention with the electronic percussion melody instrument 200, the present invention may be further configured with a transmission interface 130 as shown in fig. 2 in the foregoing apparatus 100. In one embodiment, as shown in fig. 2, the transmission interface 130 is configured to enable the controller 120 to be connected to the electronic percussion melody 200 in a wireless or wired manner so as to control the electronic percussion melody 200. In one embodiment, the aforementioned transmission interface 130 may be a wired transmission interface, and the wired transmission interface may include one or more of a music device digital interface ("Musical Instrument Digital Interface, abbreviated as MIDI"), a General-purpose I/O interface ("General-purpose input/output, abbreviated as GPIO"), a high-speed serial computer expansion bus interface ("Peripheral Component Interconnect Express, abbreviated as PCIE"), a serial peripheral interface ("Serial Peripheral Interface, abbreviated as SPI"), a universal asynchronous receiver/Transmitter ("Universal Asynchronous Receiver/Transmitter, abbreviated as UART"), and an optical fiber interface. In one application scenario, the user establishes a connection between the wired transmission interface configured in the above-mentioned apparatus 100 and the wired transmission interface in the electronic percussion melody instrument 200 through a transmission line, thereby establishing a control connection relationship between the apparatus 100 for an electronic percussion melody instrument and the electronic percussion melody instrument 200 in the present invention.
In some embodiments, the transmission interface 130 may be a wireless transmission interface, corresponding to the transmission interface 130 being a wired transmission interface. The wireless transmission interface may be one or more of interfaces such as a bluetooth interface, an infrared interface, and a WIFI interface. By the arrangement of the wireless transmission interface, the apparatus 100 of the present invention can be arranged separately from the body of the electronic percussion melody 200. This separate arrangement makes the installation of the above-described device 100 with the aforementioned electronic percussion melody instrument 200 more flexible and convenient for the user to transport and carry. In one implementation scenario, a wireless transmission interface is configured in the apparatus 100 for an electronic percussion melody instrument of the present invention, and the wireless transmission interface is exemplified as a bluetooth interface, so that a user can implement remote control of the electronic percussion melody instrument 200 through the foregoing apparatus 100. In another implementation scenario, if the wireless transmission interface is configured as a WiFi interface, the apparatus 100 for an electronic percussion melody instrument can overcome the spatial limitation, and realize remote control of the electronic percussion melody instrument 200.
In one exemplary implementation scenario, the human-machine interface 110 of the present invention may comprise a graphical user interface. In this scenario, the aforementioned mode option of the present invention may be at least one graphical element in a graphical user interface. To facilitate a better understanding of the human-machine interface 110, the following description will be made in connection with the human-machine interface 110 shown in fig. 3 and 4. As shown in fig. 3, in one implementation scenario, the graphical user interface may be implemented through a touch screen, and the user selects the performance mode by clicking on a mode option displayed on the touch screen. When the touch screen is used for selecting the graphic elements in the graphic user interface, the graphic elements of the mode options can be one graphic element formed by combining one or more mode options of xylophone, tremolo or marban. When the user clicks the mode option, a mode of repeated clicking can be adopted to switch different performance modes. Or setting a next sub-menu for the graphic element of the mode option, and further selecting a required playing mode by selecting the mode option in the next sub-menu after the user selects the mode option.
Further, the layout, color collocation and typesetting patterns of the graphic elements in the aforementioned graphic user interface may take various forms, and the graphic elements include, but are not limited to, one or more of window, key, menu, etc. In one implementation scenario, the graphic elements may be moved as desired by the user, with the commonly used graphic elements being placed in a more apparent location or in a location that is easier to click. Additionally or alternatively, the user may set different graphic elements to different colors or to different shapes for better distinguishing the graphic elements, thereby providing a more flexible and friendly human-computer interaction experience for the user.
In another implementation scenario, as shown in fig. 4, the human-machine interface 110 may be implemented by means of a display 401 and a key 402 (or a mouse), and the user inputs the performance mode selected by the user into the controller 120 by pressing a key associated with the mode option and selecting the mode option on the display using the key. In the human-machine interface 110, the keys 402 in the graphical user interface setting may be arranged in two columns or may be arranged in three columns. In some application scenarios, the keys may be set to different sizes, and the frequently used keys are set to be larger and the less frequently used keys are set to be smaller according to the frequency of use. In practical applications, a plurality of different layout forms can be provided according to the use habit of the user.
In one embodiment, the graphical user interface may also include a function menu graphical element. In one embodiment, the aforementioned function menu graphical elements may be in the form as shown in FIG. 5. As shown in fig. 5, the function menu graphic elements may include graphic elements associated with one or more of volume selection, sound effect switch, recording switch, metronome switch. Further, the function menu graphic elements can also comprise corresponding graphic elements such as up, down, selection or exit, and the user can configure the function menu graphic elements according to actual needs. In some scenarios, the aforementioned functional menu graphical elements may also be increased or decreased. Many functional menu graphic elements can be integrated into one graphic element or can be in a form of separated arrangement. In addition, a functional menu graphic element can be set as a main graphic element, and then a sub-element can be set for the functional menu graphic element, wherein the sub-element at least can comprise one or more associated graphic elements of volume selection, sound effect switch, recording switch and metronome switch.
In addition to the graphic elements of the mode options, the function menu graphic elements, and the like described above, in order to further enrich the functions of the foregoing apparatus 100, a graphic element for selecting a performance area may be provided in the graphic user interface of the present invention. In one embodiment, the above graphical user interface may further include a graphical element for setting a performance area of the electronic percussion melody instrument 200, wherein each performance mode corresponds to at least one performance area setting. In order to more visually describe the graphic element setting of the playing area of the present invention, the following is a detailed description in connection with graphic element setting diagrams of the playing area and the playing area setting on the electronic percussion melody instrument 200 shown in fig. 6-8.
In one embodiment, the human-machine interface of the present invention may also be arranged as shown in fig. 6, i.e., may further include graphic elements (performance areas 1 and 2 as exemplarily shown in the drawings) provided with respect to the performance area. In the following, a selection of a performance area using the man-machine interface shown in fig. 6 will be described by taking a marabase musical instrument as an example. As described above, the martins may have different numbers of keys according to different performance scenes. According to the aspect of the present invention, different playing areas can be divided on the electronic percussion melody instrument of the present invention for these different key numbers so as to correspond to the different key numbers of the martinbaqin, respectively. According to the number of keys of the maraba musical instrument described above, the performance areas may include six different performance area settings of the performance area 1 corresponding to 49 keys, the performance area 2 corresponding to 52 keys, the performance area 3 corresponding to 56 keys, the performance area 4 corresponding to 61 keys, the performance area 5 corresponding to 66 keys, and the performance area 6 corresponding to 69 keys. After selecting the marban in the mode options corresponding to each playing mode, the user can further select a proper playing area according to the requirement, so that the controller can call the sound source data according to the playing mode and the playing area.
In an exemplary implementation scenario, taking as an example two of the performance areas of different styles of maraba, these two performance areas correspond to the performance area 1 shown in fig. 7 (the portion 701 included in the broken line in the drawing) and the performance area 2 shown in fig. 8 (the portion 801 included in the broken line in the drawing), respectively. After the user selects the performance mode and the performance area, the controller 120 in the aforementioned apparatus 100 responds to the performance signal generated when the user performs on the electronic percussion melody 200, and the controller 120 in the apparatus 100 determines the sound source data corresponding to the performance signal according to the selected performance mode and performance area. In one scenario, if a key is included in both the playing area 1 and the playing area 2, the controller 120 may generate different tone outputs when the controller simulates the tone effect of a percussion melody by calling that the source data is not the same when the user taps the same key due to the difference in the selected playing areas. In one scenario, after the user selects a performance area, the controller may also choose not to do any further processing if a key in a performance area other than the performance area is struck. It is understood that the performance area in the above-described drawings shows only a partial, not an entire, performance area of the electronic percussion melody for the purpose of illustration only. In addition, the above-described setting of the performance area is exemplary and not restrictive, and those skilled in the art can set other different forms of performance areas according to different application scenes or actual conditions.
In one embodiment, in response to receiving the performance signal from the electronic percussion melody instrument 200, the controller 120 may be further configured to determine sound source data corresponding to the performance signal according to the selected performance mode and the set performance area so as to obtain the sound effect of the simulated electronic percussion melody instrument 200 using the sound source data. For example, in one implementation scenario, the user selects a martins as needed and sets the performance area 1. When performing on the electronic percussion melody instrument 200, the controller 120 of the aforementioned apparatus 100 determines sound source data corresponding to a performance signal according to a selected maraba musical performance mode and a set performance area 1 in response to receiving the performance signal from the electronic percussion melody instrument 200, thereby facilitating a subsequent process of simulating the sound effect of the electronic percussion melody instrument 200 using the sound source data. If the user selects the performance area 2, the controller 120 of the apparatus 100 in the present embodiment determines sound source data corresponding to a performance signal according to the selected martins performance mode and the set performance area 2 in response to receiving the performance signal from the electronic percussion melody 200 while performing on the electronic percussion melody 200. It will be appreciated that the sound source data of the present invention has a one-to-one correspondence with the different playing areas described above, which can be expressed by a mapping table, for example. Based on the mapping relationship, the controller 120, upon receiving the performance signal from the electronic percussion melody instrument 200, may call the corresponding sound source data according to the position information in the performance signal in combination with the performance mode and the performance area selected by the user.
In one embodiment, the apparatus 100 of the present invention further comprises a storage structure arrangement. In one implementation scenario, the apparatus 100 of the present invention includes at least an internal memory 140 and an external memory 150 as shown in FIG. 9. The internal memory is connected to the controller 120 and configured to store sound source data of different electronic percussion melody instruments. Depending on the application scenario, internal memory 140 may be one or more of registers, cache, and main memory, among other storage devices. Based on such an arrangement, the user can write desired sound source data in advance in the internal memory of the device 100 in the present embodiment, so that the controller 120 calls out sound source data of the corresponding key according to the performance signal and the performance mode.
In addition to the above-described manner of setting the internal memory 140 to store sound source data, an external memory interface for connecting an external memory storing sound source data of different electronic percussion melody instruments may be provided in the present embodiment. In some scenarios, the external memory may be a hard disk, floppy disk, ZIP disk, U-disk, tape, or the like. Through the setting of the external memory interface, a user can update the sound source data at any time according to the requirements, and can select the sound source data of different types of percussion melody instruments to store according to the requirements, so that the user experience is effectively improved.
In one embodiment, the sound source data includes sound source data for one or more of xylophone (xylophone), tremolo (vibraphone), marimba (marimba), delphine (celesta), and glockenspiel (glockenspiel). In order to facilitate understanding of sound source data, the present embodiment is described by a sound source data storage schematic diagram as shown in fig. 10. The sound source data [0] to sound source data [ n ] represent waveform data, wherein the sound source data [0] is waveform data of the lowest sound, the sound source data [ n ] is waveform data of the highest sound, the sound source data corresponds to keys one by one, and the value of n depends on the quantity of the keys. In addition, the sound source data also includes note numbers, tone parameters and sound effects, wherein the tone parameters include waveform addresses, frequency data, envelope data, and the like. When a user plays, the controller 120 in the apparatus 100 calls the corresponding sound source data to output by analyzing the information of the key position, the vibration intensity, the signal generation time, etc. in the playing signal, so that the electronic percussion melody instrument simulates the tone signal in the corresponding playing mode.
In one embodiment, the human-machine interface 110 may be disposed at an electronic percussion melody, a smartphone, a computer, and/or a cloud server. In one application scenario, the human-machine interface 110 may be disposed at the electronic percussion melody instrument 200, including disposing the human-machine interface 110 on the electronic percussion melody instrument 200, or integrating the human-machine interface 110 with a control panel of the electronic percussion melody instrument 200 and directly connected to a control chip of the electronic percussion melody instrument 200. In yet another application scenario, the human-computer interface 110 may be installed in a smart phone by means of APP, or the human-computer interface 110 may be implemented in a computer or a cloud server by means of corresponding software and a web page, and a connection is established between the human-computer interface 110 and the electronic percussion melody instrument 200 by means of wireless communication, so that a space limitation on a control process of the electronic percussion melody instrument is overcome, and a better application effect can be achieved in multiple application scenarios such as online teaching and remote training. And the manufacturer does not need to specially produce the corresponding hardware device for man-machine interaction any more, thereby facilitating the mass production of the device 100.
The operation of the device of the present invention will be further described below taking as an example the control of different performance effects of maraba and xylophone on one electronic percussion melodic instrument. And the user selects a playing mode of the Martinbaqin from mode options of a human-computer interface so as to control the electronic percussion melody instrument body to work in the playing mode of the Martinbaqin. The player plays in the beating area of the electronic beating melody instrument body, and various playing signals generated in the playing process are sensed by the detecting device on the electronic beating melody instrument body, wherein the playing signals at least comprise the playing signals such as the position signals, the force signals and the beating time of the keys. The detecting means then converts the performance signal into a corresponding electrical signal and outputs it after detecting it. In the device for the electronic percussion melody instrument, the controller is in communication connection with the electronic percussion melody instrument, so that the electric signal corresponding to the playing signal is obtained. After receiving the playing signal, the controller in the device of the invention retrieves the corresponding sound source data of the key from the memory (the internal memory or the external memory) according to the playing mode selected by the user through the man-machine interface, thereby determining the received sound source data corresponding to the playing signal. After specific sound source data are determined, the sound effect of the Marinbred musical instrument can be conveniently simulated by using the sound source data.
Further, since there are at least the aforementioned 6 cases in the number of keys of the maraba, the maraba is correspondingly provided with at least 6 different performance area settings. After the user selects the playing mode of the martinbaqin in the mode options of the man-machine interface, before confirming that the setting is completed, the user can further select a proper playing area according to the playing requirement, and if the playing area 3 corresponding to the 56 keys is selected, the controller controls the electronic percussion melody instrument according to the selected playing mode, and also controls the electronic percussion melody instrument in combination with the selected playing area. Specifically, the specific process of determining the sound source data by the controller according to the selected performance mode and performance area is described in detail in the foregoing embodiments, and will not be described herein.
In addition to the above-described selection of the performance mode of the maraba, if the user wants to switch to the performance effect of the xylophone, the electronic percussion melody instrument is switched to the performance mode of the xylophone by switching the mode option on the man-machine interface, thereby controlling the electronic percussion melody instrument to switch to the sound effect of the xylophone. When a player plays with the electronic percussion melody instrument, the controller determines that the playing signal corresponds to the sound source data of the xylophone according to the received playing signal formed by the player in the striking area and the selected playing mode of the xylophone, so as to simulate the playing sound effect of the xylophone and output the sound effect through the playing device.
Further, the human-machine interface of the present invention can also provide different performance area settings in different performance modes. According to the preference of the user, different playing areas in the xylophone playing mode can be set through a human-computer interface. The performance area may, for example, select an area which is easier to be struck by the user in the entire key area. It will be appreciated that the sound source data stored in the internal memory or the external memory and the different playing areas described above have a one-to-one correspondence relationship, which can be expressed by a map table, for example, and the map table can be stored in the internal memory or the external memory together with the sound source data described above. When playing, the controller may call corresponding sound source data according to the position information in the performance signal and in combination with the performance mode and the performance area selected by the user after receiving the performance signal from the electronic percussion melody instrument.
Based on the device for the electronic percussion melody instrument provided by the scheme, a user selects a required playing mode through a human-computer interface, and the controller determines sound source data corresponding to the playing signal according to the selected playing mode and the received playing signal of the electronic percussion melody instrument, so that the playing effect of multiple percussion melody instruments can be supported on one electronic percussion melody instrument. Through the arrangement of the electronic percussion melody instrument, a user can control the electronic percussion melody instrument through different selections on a human-computer interface and adjust the playing mode of the electronic percussion melody instrument, so that different percussion melody instruments such as a xylophone, a tremolo, a marinbred musical instrument and the like are simulated.
In addition, the scheme of the invention also provides an electronic percussion melody instrument. For convenience of understanding, the internal composition of the electronic percussion melody instrument of the invention is explained in detail in the structure shown in fig. 11. In one embodiment, the electronic percussion melody instrument may include an electronic percussion melody instrument body and the apparatus 100 for an electronic percussion melody instrument described above. The electronic percussion melody instrument may be provided with a striking area, and the striking area is capable of generating a performance signal when played. The apparatus 100 for an electronic percussion melody may control the body of the electronic percussion melody via the man-machine interface 110 so that the electronic percussion melody simulates sound effects of different electronic percussion melodies in different performance modes.
It should be understood that the electronic percussion melody body should also have a general outline configuration of the electronic percussion melody, and may include a body with a surface on which a plurality of keys may be arranged. The modules such as keys of the electronic percussion melody instrument are not limited to special wood, can be made of metal or composite materials, and are more convenient for industrial production. The aforementioned electronic percussion melody body should further include a playing device for outputting a tone signal. The playback device may be a speaker including a power amplifier so that the outputted musical sound signal is amplified and played back in the form of sound. Further, the body may include a cavity that may house the power module and other accessory circuit board modules therein. The outer surface of the body is also provided with various external transmission interfaces, so that the connection with other external devices is convenient.
In addition, the electronic percussion melody instrument body may be provided with a detecting device for detecting a performance signal generated by striking the striking area, for sensing a physical response of a player to a key stroke and converting the physical response into an electric signal. In one implementation scenario, the detection device may be a magnetic induction area disposed in the striking area, where the magnetic induction area may be disposed under the key in a close contact manner, and generate a corresponding detection signal by using an electromagnetic signal sensed during playing. Specifically, the magnetic induction region is set as a striking region of a key of an electronic percussion melody instrument, thereby realizing non-contact triggering to generate a corresponding detection signal. In some other implementation scenarios, the detection device may also be provided with one or more of a pressure sensor, a vibration sensor, a position sensor, a capacitance sensing circuit, an ultrasonic sensor, and other detection devices at a position close to the key, so as to detect the performance signal formed in the striking area. When the key receives the pressure signal, the pressure is transmitted to the sensors, so that the sensors generate corresponding electric signals according to the magnitude of the pressure signal as performance signals, and the controller in the device of the invention can conveniently perform corresponding processing according to the performance signals. The types, the number and the layout modes of the detection devices can be flexibly configured according to actual needs and application scenes. In addition, the detection device can further comprise corresponding sound absorbing materials, a filtering module and the like, so that more accurate performance signals can be conveniently obtained, and user experience is improved.
