请参阅图5,图5是本申请弹拨乐器的模拟设备第五实施方式的结构示意框图。在本实施方式中,弹拨乐器的模拟设备50包括触摸显示屏51、转换模块52、发声设备53以及壳体55。
触摸显示屏51显示弹拨乐器的操作部分,例如钢琴的琴键、古筝等的琴弦,并且还根据用户在触摸显示屏51的显示面的触碰而产生第一电信号。优选的,触摸显示屏51为电容式触摸显示屏。触摸显示屏51一般分为电阻式触摸显示屏与电容式触摸显示屏,而相对于电阻式触摸显示屏来说,电容式触摸显示屏的定位更加精准,并且反应灵敏,还便于进行多点触碰的识别。因此,采用电容式触摸显示屏能够带给用户更加真实准确的体验。另外,为了尽量仿真,还可以将触摸显示屏51的显示面设置为长方形或弹拨类乐器的形状。
转换模块52连接触摸显示屏51,用于接收触摸显示屏51被触碰而产生的第一电信号,并将该第一电信号转换成声音信号。发声设备53与转换模块52连接,用于接收声音信号并发出与声音信号对应的弹拨乐器的声音。在本实施方式中,转换模块52包括检测电路521、存储器522、转换电路523。其中,检测电路521连接触摸显示屏51,用于检测触摸显示屏51被触碰而产生的第一电信号,并产生相应的检测信号;存储器522内存储有音频库5221,音频库5221中包括至少一种弹拨乐器的声音所对应的声音信号;转换电路523包括处理器5231和音频解码器5232,处理器5231连接检测电路521,并将检测信号转换成用于表示对应音频的数字信号流;音频解码器5232连接处理器5231与存储器522,并根据数字信号流调用音频库5221中的声音信号。
触摸显示屏51的显示面露出于壳体55,转换模块52与发声设备53设置于壳体55中。壳体55可以采用常用的硬质塑料材质,也可以使用金属材质,或者是木制材质。壳体55的设置是为了保护触摸显示屏51、转换模块52以及发声设备53,可以做成防水结构以进行更完善的保护。另外,为了保证触摸显示屏51的亮度符合环境的亮度,本实施方式中在壳体55上设置有感光元件54。感光元件54与处理器5231连接,检测外部光线强度并形成第二电信号发送至处理器5231。处理器5231进一步根据第二电信号调整触摸显示屏51的亮度。当然,感光元件54在其他实施方式中可省略。
触摸显示屏、转换模块以及发声设备在其各自的领域均为成熟产品,造价低廉,因此整合之后形成的成品弹拨乐器的模拟设备造价同样低廉,比真正的弹拨乐器售价更低,能够让更多的用户消费的起。并且,占用面积小,节约空间。另外,由于是根据电信号来转为声音信号,完全可以在音频解码器中增加相应的音量调节电路,来控制声音的大小,在练习时不会干扰到其他人,可随时随地练习。
在上述实施方式中,弹拨乐器的模拟设备还可包括耳机插口或扬声器,连接音频解码器,并接收音频解码器输出的声音信号。耳机插口将此声音信号传输至耳机,用户佩戴耳机时便完全不会对外部环境造成影响。扬声器直接将该声音信号进行播放,适合在有人教导时使用。另外,耳机插口可以设置有多个,从而可插入多个耳机,供多人进行听取,也可实现在有人教导时使用。
优选地,模拟设备上还可以设置有电源,与处理器或全部电子器件连接,电源与处理器或全部电子器件之间设置有一个开关,该开关至少部分暴露于琴体外。电源可以是电池,也可以是一个接外部电力的转换器。
优选地,检测电路及转换电路中可以以Linux系统为平台,搭配音频解码库,如FFMPEG库。
本申请的有益效果是:区别于现有技术的情况,本申请提供的弹拨乐器的模拟设备通过触摸显示屏来模拟弹拨乐器的弹奏部件的显示,通过用过户碰触产生的电信号转换为声音信号,不需要真正的乐器就可以进行练习,并且造价低廉,并且由于是电信号转换为声音信号,其大小可调,可随时随地练习。
以上所述仅为本申请的实施方式,并非因此限制本申请的专利范围,凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本申请的专利保护范围内。
