本申请要求于2021年5月10日申请的，申请号为2021105064616，名称为“用于电子打击旋律乐器的装置和电子打击旋律乐器”的中国专利申请的优先权。
技术领域
本发明一般地涉及乐器领域。更具体地，本发明涉及一种用于电子打击旋律乐器的装置和电子打击旋律乐器。
背景技术
传统的打击旋律乐器是通过敲打乐器本体而发出声音的。具体来说，通过演奏者对乐器本体的敲打，打击旋律乐器能够产生节奏、旋律和合声等各种音效。根据演奏场景和听众的偏好，表演者可以选择演奏木琴、颤音琴或马林巴琴等打击旋律乐器。如本领域技术人员所知，就琴键数目而言，不同的打击旋律乐器可以布置有不同数目的琴键。以马林巴琴为例，其键数可以是49键、52键、56键、61键、66键或69键。就结构而言，一些电子打击旋律乐器还带有共鸣管、扇叶、转动器等结构。以颤音琴为例，颤音琴中在各支管顶上加装有可转动的扇叶，并且琴键下方设置有共鸣管。尽管目前的打击旋律乐器丰富多样，但是却无法在一个打击旋律乐器上实现多种打击旋律乐器的演奏特点，从而导致在一个打击旋律乐器上无法实现丰富多样的演奏效果。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
打击旋律乐器是通过敲打由振动材料制成的琴键等击打区域而发出声音的。对应地，电子打击旋律乐器的设计也可以通过检测琴键处的振动信号和位置信号，从而通过处理这样的信号来模拟出相应打击旋律乐器的音效。为了在演奏过程中采集信号，电子打击旋律乐器在击打区(例如琴键区)可以设置有相应的检测振动信号和位置信号等各种类型的传感器，以便根据检测到的演奏信号来模拟出不同乐器的音效。具体地，通过对击打区域的敲击过程的检测，传感器可以将敲击所产生的机械能转换为电流形式的电能。这里，电流的大小可以依敲击力度的不同而不同。此后，电子打击旋律乐器中的控制器可以根据该电流信号来确定与敲击区对应的音源数据，并且生成对应的音效并通过播放设备来输出。
如本领域技术人员所知，当前的打击旋律乐器类型丰富，包括例如木琴、颤音琴、马林巴琴和钟琴等。每种打击旋律乐器的琴键数量也不相同，单就马林巴琴而言，其键数就有至少6种情况，而木琴、颤音琴等与马林巴琴的键数也不相同。另外，有的电子打击旋律乐器还带有共鸣管、扇叶、转动器等结构，使得打击旋律乐器体积偏大而不便于携带。鉴于打击旋律乐器存在前述的情形，演奏者期望在一个电子打击旋律乐器上就能实现演奏多种电子打击旋律乐器之一的演奏体验和演奏音效。这样，一方面，演奏者无需为演奏不同的电子打击旋律乐器而分别购买不同的乐器，从而显著减小演奏操作的成本。另一方面，由于不需要多个电子打击旋律乐器，演奏者可以仅安置一个电子打击旋律乐器，从而方便乐器的布置并且明显减小占地空间。
为此，本发明提出用于电子打击旋律乐器的装置，以实现多功能的电子打击旋律乐器。具体地，用户可以通过利用本发明装置中的人机界面对电子打击旋律乐器本体进行控制，例如选择演奏模式。进一步，在选择的演奏模式中，控制器可以根据接收到的电子打击旋律乐器的演奏信号来确定对应于演奏信号的音源数据并且指示输出装置进行播放，从而实现在一个电子打击旋律乐器上获得多种电子打击旋律乐器之一的演奏效果。
下面将结合附图对本发明的多个实施例进行详细地描述。
图1是示出根据本发明实施例的用于电子打击旋律乐器的装置100的组成示意图。
如图1所示，装置100可以包括人机界面110和控制器120。在一个实施例中，该人机界面110可以与电子打击旋律乐器200进行连接，从而实现与电子打击旋律乐器200之间的人机交互。具体地，人机界面110至少可以包括用于选择电子打击旋律乐器200的演奏模式的模式选项，并且其中电子打击旋律乐器不同的演奏模式可以模拟不同打击旋律乐器的音效。在一个实施例中，控制器120可以配置用于接收用户经由模式选项对电子打击旋律乐器演奏模式的选择。进一步地，响应于接收到的来自电子打击旋律乐器200的演奏信号，前述控制器120可以根据选择的演奏模式来确定对应于该演奏信号的音源数据，以便使用音源数据来获得模拟的电子打击旋律乐器的音效。
就上文的模式选项而言，根据不同的应用场景，本实施例的人机界面110中可以设置 有用于选择木琴、颤音琴或马林巴琴等电子打击旋律乐器的音效的模式选项。在演奏前，用户可以根据需要选择任意一种前述的模式选项。以马林巴琴为例，在进行演奏时，控制器120根据接收到的来自电子打击旋律乐器200的演奏信号和前述选择的演奏模式为马林巴琴的模式选项，确定该演奏信号对应的马林巴琴的音源数据，方便后续电子打击旋律乐器200根据确定的音源数据模拟出马林巴琴的音效。此处的演奏信号可以包括琴键被按压或击打的力度、位置和时间等信息。在不同的应用场景中，前述的演奏信号可以由布置于本发明的电子打击旋律乐器本体(下文稍后描述)中的一个或多个传感器来采集。
为了将本发明的装置100同电子打击旋律乐器200建立连接，本发明在前述的装置100中还可以配置如图2中所示出的传输接口130。在一个实施例中，如图2所示，传输接口130配置用于使得控制器120以无线或有线方式与电子打击旋律乐器200连接，以便对电子打击旋律乐器200进行控制。在一个实施例中，前述的传输接口130可以是有线传输接口，有线传输接口可以包括音乐设备数字接口(“Musical Instrument Digital Interface，简称MIDI”)、通用I/O接口(“General-purpose input/output，简称GPIO”)、高速串行计算机扩展总线接口(“Peripheral Component Interconnect Express，简称PCIE”)、串行外设接口(“Serial Peripheral Interface，简称SPI”)、通用异步收发传输器(“Universal Asynchronous Receiver/Transmitter，简称UART”)和光纤接口等接口的一个或者多个。在一个应用场景中，用户通过传输线将上述装置100中配置的有线传输接口和电子打击旋律乐器200中的有线传输接口建立连接，从而建立本发明中的用于电子打击旋律乐器的装置100和电子打击旋律乐器200的控制连接关系。
与上述传输接口130为有线传输接口相对应的，在一些实施例中，前述的传输接口130也可以是无线传输接口。该无线传输接口可以是例如蓝牙接口、红外接口和WIFI接口等接口中的一个或者多个。通过无线传输接口的设置，本发明的装置100能够和电子打击旋律乐器200的本体分离设置。这种分离设置的方式，使得上述装置100同前述电子打击旋律乐器200的安装形式更加灵活，方便用户运输和携带。在一个实现场景中，在本发明的用于电子打击旋律乐器的装置100中配置无线传输接口，以该无线传输接口为蓝牙接口为例，用户能够通过前述装置100实现对电子打击旋律乐器200的远距离控制。在另一个实现场景中，配置无线传输接口为WiFi接口，则用于电子打击旋律乐器的装置100就能够克服空间限制，实现对电子打击旋律乐器200的远程控制。
在一个示例性的实现场景中，本发明的人机界面110可以包括图形用户界面。在该场景下，本发明的前述模式选项可以是图形用户界面中的至少一个图形元素。为了便于更好的理解该人机界面110，下面将结合图3和图4中所示出的人机界面110进行阐述。如图3所示，在一个实现场景中，图形用户界面可以通过触摸屏实现，用户通过点触触摸屏上所显示的模式选项，从而对演奏模式进行选择。在利用触摸屏对图形用户界面中的图形元素进行选择时，前述的模式选项的图形元素可以是木琴、颤音琴或马林巴琴等模式选项的一种或多种组合在一起形成的一个图形元素。用户在点选模式选项时，可以采用重复点选的方式切换不同的演奏模式。或者是为模式选项的图形元素设置下一级子菜单，用户通过选取模式选项后，进一步通过选取下一级子菜单中的模式选项选择需要的演奏模式。
进一步地，前述的图形用户界面中图形元素的布局、颜色的搭配和排版样式可以有多种形式，图形元素包括但不限于窗口、按键和菜单等形式的一种或多种。在一个实现场景中，根据用户需要可以挪动图形元素，将常用的图形元素设置在较为明显的位置、或者是 比较容易点选的位置。附加地或替代地，用户也可以为了更好的区分图形元素，将不同的图形元素设置为不同的颜色，或者是设置为不同的形状，从而给用户带来更加灵活、友好的人机交互体验。
在另一种实现场景中，如图4所示，人机界面110可以通过显示屏401和按键402(或鼠标)的方式实现，用户通过按压关联该模式选项的按键，利用按键选择显示屏上的模式选项，从而将用户选取的演奏模式输入控制器120。该人机界面110中，图形用户界面设置中的按键402分两列设置，也可以设置为三列。在一些应用场景中，也可以将按键设置为不同的大小，根据使用频次将常用的按键设置大一些，将不常用的按键设置相对小一些。在实际应用中，根据用户使用习惯可以提供多种不同的布局形式。
在一个实施例中，图形用户界面还可以包括功能菜单图形元素。在一个实施例中，前述的功能菜单图形元素可以是如图5中所示出的形式。如图5所示，功能菜单图形元素可以包括与音量选择、音效开关、录音开关、节拍器开关中的一种或多种设置关联的图形元素。进一步地，功能菜单图形元素还可以包括相应的向上、向下、选择或退出等图形元素，用户可根据实际需要对功能菜单图像元素进行配置。在一些场景中，前述的功能菜单图形元素还可以增加或减少。很多个功能菜单图形元素都可以集成在一个图形元素中，也可以采用分开设置的形式。另外，也可以设置一个功能菜单图形元素作为主图形元素，然后可以为该功能菜单图形元素设置子元素，子元素中至少可以包括音量选择、音效开关、录音开关、节拍器开关中的一种或多种关联的图形元素。
除了上述模式选项的图形元素、功能菜单图形元素等，为了进一步丰富前述装置100的功能，本发明的图形用户界面中，还可以设置用于选取演奏区域的图形元素。在一个实施例中，上文的图形用户界面还可以包括用于设置电子打击旋律乐器200的演奏区域的图形元素，其中每种演奏模式对应于至少一种演奏区域设置。为了更加形象地描述本发明的演奏区域的图形元素设置，下面结合图6-图8中所示出的演奏区域的图形元素设置示意图和电子打击旋律乐器200上的演奏区域设置进行详细说明。
在一个实施例中，本发明的人机界面还可以布置成如图6所示的，即还可以包括关于演奏区域设置的图形元素(如图中示例性示出的演奏区域1和2)。下面将以马林巴琴为例来阐述如何使用图6所示人机界面来实现对演奏区域的选择。如前所述，根据不同的演奏场景，马林巴琴可以具有不同的键数。根据本发明的方案，可以针对这些不同的键数来在本发明的电子打击旋律乐器上划分不同的演奏区，以分别对应于马林巴琴的不同键数。根据前述的马林巴琴的键数，演奏区域可以包括对应49键的演奏区域1，对应52键的演奏区域2，对应56键的演奏区域3，对应61键的演奏区域4，对应66键的演奏区域5和对应69键的演奏区域6这六种不同的演奏区域设置。用户在各演奏模式对应的模式选项中选择马林巴琴后，可以进一步根据需求选择合适的演奏区域，以便控制器依据该演奏模式和演奏区域调取音源数据。
在一个示例性的实现场景中，以马林巴琴的其中两种不同风格的演奏区域为例，这两种演奏区域分别对应如图7所示出的演奏区域1(图中虚线包括的部分701)和图8示出的演奏区域2(图中虚线包括的部分801)。用户在选择了演奏模式和演奏区域后，前述装置100中的控制器120响应于用户在电子打击旋律乐器200上演奏时产生的演奏信号，装置100中的控制器120会根据选择的演奏模式和演奏区域确定对应该演奏信号的音源数据。在一个场景中，如果某个琴键既包含在演奏区域1又包含在演奏区域2中时，则可能 会由于选取的演奏区域的不同，使得用户在敲击同一个琴键时，控制器120通过调用得到的音源数据并不相同，从而模拟某种打击旋律乐器音效时产生不同的琴音输出。在一个场景中，在用户选择好演奏区域后，如果敲击到非该演奏区域内的琴键，则控制器也可以选择不做任何的进一步处理。可以理解的是，仅为了示例的目的，上述附图中的演奏区域仅示出电子打击旋律乐器的局部而非整体的演奏区域。另外，上述演奏区域的设置是示例性的而非限制性的，本领域技术人员根据不同的应用场景或实际条件也可以设置其他不同形式的演奏区域。
在一个实施例中，响应于接收到来自电子打击旋律乐器200的演奏信号，控制器120还可以配置用于根据选择的演奏模式和设置的演奏区域来确定对应于演奏信号的音源数据，以便使用音源数据来获得模拟的电子打击旋律乐器200的音效。举例来说，在一个实现场景中，用户根据需要选择马林巴琴并且设置了演奏区域1。当在电子打击旋律乐器200上进行演奏时，前述装置100的控制器120响应于接收到来自电子打击旋律乐器200的演奏信号，根据选择的马林巴琴演奏模式和设置的演奏区域1，确定对应演奏信号的音源数据，从而方便后续的利用音源数据模拟电子打击旋律乐器200的音效的过程。如果用户选择的是演奏区域2，则在电子打击旋律乐器200上进行演奏时，本实施例中的装置100的控制器120响应于接收到来自电子打击旋律乐器200的演奏信号，根据选择的马林巴琴演奏模式和设置的演奏区域2，确定对应演奏信号的音源数据。可以理解的是，本发明的音源数据和前述的不同演奏区域存在一一对应的关系，该关系例如可以通过映射表来表达。基于该映射关系，控制器120在接收到来自电子打击旋律乐器200的演奏信号后，可以根据演奏信号中的位置信息并且结合用户选取的演奏模式和演奏区域来调取对应的音源数据。
在一个实施例中，本发明的装置100还包括存储结构设置。在一个实现场景中，本发明的装置100至少包括如图9所示的内部存储器140和外部存储器150。该内部存储器与控制器120连接并且配置用于存储不同电子打击旋律乐器的音源数据。根据不同的应用场景，内部存储器140可以是寄存器、高速缓冲存储器和主存储器等存储设备中的一种或多种。基于这样的布置，用户可以将所需要的音源数据提前写入本实施例中装置100的内部存储器中，以便控制器120根据演奏信号和演奏模式调取对应琴键的音源数据。
除了上述设置内部存储器140存储音源数据的方式，本实施例中还可以设置外部存储器接口150，该外部存储器接口150用于连接存储有不同电子打击旋律乐器的音源数据的外部存储器。在一些场景中，外部存储器可以是硬盘、软盘、ZIP盘、U盘、磁带等。通过外部存储器接口150的设置，用户可以根据需求随时对音源数据进行更新，也可以根据需要选择不同类型的打击旋律乐器的音源数据进行存储，从而有效提升用户体验。
在一个实施例中，音源数据包括针对于木琴(xylophone)、颤音琴(vibraphone)、马林巴琴(marimba)、钢片琴(celesta)、钟琴(glockenspiel)中的一种或多种的音源数据。为了便于理解音源数据，本实施例通过如图10所示的音源数据存储示意图进行说明。音源数据[0]～音源数据[n]代表波形数据，其中音源数据[0]是最低音的波形数据，音源数据[n]是最高音的波形数据，其中音源数据与琴键一一对应，n值的大小取决于琴键数量的多少。另外，音源数据还包括音符编号、音色参数和声效等，其中的音色参数包括波形地址、频率数据和包络数据等。当用户演奏时，前述装置100中的控制器120通过解析演奏信号中的琴键位置、振动强度、信号产生时间等信息，调用对应的音源数据进行输出，以便电子打击旋 律乐器模拟对应演奏模式下的琴音信号。
在一个实施例中，人机界面110可以布置于电子打击旋律乐器、智能手机、电脑和/或云端服务器处。在一个应用场景中，可以将人机界面110布置于电子打击旋律乐器200处，包括在电子打击旋律乐器200上设置人机界面110，或者是将人机界面110集成于电子打击旋律乐器200的控制面板，并和电子打击旋律乐器200控制芯片直接连接。在又一个应用场景中，还可以将人机界面110通过APP的方式安装于智能手机中，也可以在电脑或云端服务器通过相应的软件、网页实现人机界面110，并通过无线通讯的方式和电子打击旋律乐器200建立连接，从而克服了对电子打击旋律乐器控制过程的空间限制，在线上教学、远程训练等多个应用场景中都能实现较好的应用效果。并且生产厂家不需要再专门生产对应的用于人机交互的硬件装置，便于前述装置100的批量化生产。
下面以在一个电子打击旋律乐器上控制实现马林巴琴和木琴的不同演奏效果为例进一步描述本发明的装置的工作原理。用户在人机界面的模式选项中选择马林巴琴的演奏模式，以控制电子打击旋律乐器本体工作在马林巴琴的演奏模式下。演奏者在电子打击旋律乐器本体的击打区进行演奏，其演奏过程中产生的各类演奏信号被电子打击旋律乐器本体上的检测装置感应，该演奏信号应当至少包括琴键的位置信号、力度信号和敲击时间等演奏信号。然后检测装置在检测到该演奏信号后将其转换为相应的电信号并输出。本发明中用于电子打击旋律乐器的装置中的控制器与电子打击旋律乐器通信连接，从而获取到上述演奏信号对应的电信号。本发明的装置中的控制器在接收到上述演奏信号后，根据用户通过人机界面选取的演奏模式，从存储器(内部存储器或外部存储器)中调取该琴键对应的音源数据，从而确定接收到的该演奏信号对应的音源数据。在确定具体的音源数据后，方便后续利用音源数据模拟出马林巴琴的音效。
进一步地，由于马林巴琴的键数有至少前述6种情况，因而马林巴琴对应有至少6种不同的演奏区域设置。上述用户在人机界面的模式选项中选择马林巴琴的演奏模式之后，在确认设置完成之前，用户还可以根据演奏需求，进一步选取合适的演奏区域，如果选取对应56键的演奏区域3，则控制器除了根据选取的演奏模式对电子打击旋律乐器本体进行控制之外，还要结合选取的演奏区域对电子打击旋律乐器进行控制。具体地，控制器根据选取的演奏模式和演奏区域确定音源数据的具体过程已在前述实施例中详细说明，此处不再赘述。
除了上述介绍的选取马林巴琴的演奏模式之外，如果用户想要切换为木琴的演奏效果，则通过切换人机界面上的模式选项将该电子打击旋律乐器切换为木琴的演奏模式，从而控制电子打击旋律乐器切换为木琴的音效。演奏者在利用电子打击旋律乐器进行演奏时，控制器将根据接收到的演奏者在击打区形成的演奏信号和选取的木琴的演奏模式，确定演奏信号对应于木琴的音源数据，以便模拟出木琴的演奏音效并通过播放设备来输出。
进一步地，本发明的人机界面还可以提供在不同演奏模式下的不同演奏区域设置。根据用户的偏好，可以通过人机界面设置在该木琴演奏模式下的不同演奏区域。该演奏区域例如可以选取整个琴键区域中用户更容易敲击到的区域。可以理解的是，内部存储器或外部存储器中存储的音源数据和前述的不同的演奏区域存在一一对应的关系，该关系例如可以通过映射表来表达，并且该映射表可以与前述的音源数据一同存储在内部存储器或外部存储器中。在演奏时，控制器在接收到来自电子打击旋律乐器的演奏信号后，可以根据演奏信号中的位置信息并且结合用户选取的演奏模式和演奏区域调取对应的音源数据。
基于上述方案提出的本发明的用于电子打击旋律乐器的装置，用户通过人机界面选择需要的演奏模式，控制器根据选取的演奏模式和接收到的电子打击旋律乐器的演奏信号，确定演奏信号对应的音源数据，实现了在一个电子打击旋律乐器上就能够支持多种打击旋律乐器的演奏效果。通过本发明中用于电子打击旋律乐器的设置，用户能够在人机界面上透过不同的选择，对电子打击旋律乐器进行控制，调整电子打击旋律乐器的演奏模式，从而模拟出木琴、颤音琴、马林巴琴等不同打击旋律乐器。
另外，本发明的方案还提供了一种电子打击旋律乐器。为了便于理解，本发明中该电子打击旋律乐器的内部组成形式以如图11中示出的结构进行详细阐述。在一个实施例中，该电子打击旋律乐器可以包括电子打击旋律乐器本体和前述的用于电子打击旋律乐器的装置100。电子打击旋律乐器上可以布置有击打区，并且该击打区在演奏时能够产生演奏信号。上述用于电子打击旋律乐器的装置100可以经由人机界面110对电子打击旋律乐器本体进行控制，以便电子打击旋律乐器在不同的演奏模式中模拟不同电子打击旋律乐器的音效。
可以理解的是，上述的电子打击旋律乐器本体还应当具有一般通用的电子打击旋律乐器外形构造，可以包括琴体，其表面可以布置有多个琴键。该电子打击旋律乐器的琴键等模块不再限制于使用特殊木材，可通过金属或者复合材料制成，更加便于工业化生产。前述的电子打击旋律乐器本体还应当包括用于输出琴音信号的播放设备。该播放设备可以是包括功率放大器的扬声器，以便将输出的琴音信号经过放大并通过声音的形式播放出来。进一步地，该琴体可以包括腔体，其内部可以容纳电源模块和其他附属电路板模块。该琴体的外表面还应布置有各种对外传输接口，从而方便和其他外部设备连接。
另外，前述电子打击旋律乐器本体上可以设置有检测敲击上述击打区时产生的演奏信号的检测装置，用于感应演奏者对琴键敲击所产生的物理响应并且将该物理响应转换成电信号。在一个实现场景中，该检测装置可以是在击打区设置的磁感应区，该磁感应区可以紧贴布置于琴键的下方，利用演奏时感应到的电磁信号生成相应的检测信号。具体地，将磁感应区设置成电子打击旋律乐器的琴键的击打区，从而实现非接触式触发以产生相应的检测信号。在一些其他实现场景中，上述检测装置也可以在紧贴琴键位置处设置压力传感器、振动传感器、位置传感器、电容感应电路和超声波传感器等检测装置中的一种或多种，从而检测前述击打区中形成的演奏信号。当琴键收到压力信号时，将压力传递给前述传感器，从而这些传感器根据压力信号的大小产生相应的电信号作为演奏信号，便于本发明中装置中的控制器根据该演奏信号进行相应的处理过程。上述检测装置的种类、数量和布局方式可根据实际需要和应用场景进行灵活配置。另外，上述检测装置还可以包括相应的吸音材料和滤波模块等，从而便于获取更加精准的演奏信号，提升用户体验。
