用于簧管乐器的设备
摘要：
参照图7a，本发明涉及与具有形成谐振腔的气室(15)的簧管乐器(201)一起使用的换能器设备(200)，该谐振腔的谐振特性通过打开和封闭将气室连通到簧管乐器的外部的音孔(17A、17B)来控制。换能器设备包括用于将该换能器设备可释放地固定到簧管乐器的吹嘴(201)以代替簧片的附接装置(202)。簧片替换部分(203)具有壳体，该壳体具有邻接表面，用于邻接吹嘴的表面部分，该表面部分将与固定到吹嘴的簧片邻接。空气通道从进气口(211)延伸穿过簧片替换部分(203)的壳体，通过该进气口，乐器的演奏者可以吹气到出气口(213)，演奏者吹入的空气通过该出气口被传送到大气中，而不经过簧管乐器内的气室(15)。扬声器(208)由壳体支撑并将声音传送到气室(15)。气室麦克风(209)由壳体支撑并接收气室(15)中的声音。电子处理单元(204)具有：激励单元(101)，其产生用于驱动扬声器(208)的激励信号；处理器(102)，其用于接收由麦克风产生的测量信号并根据该测量信号检测由乐器演奏的音符；合成器(220)，其用于生成体现与所检测到的音符相对应的音符的电子信号；以及输出装置(103)，其用于将合成器生成的音符发送到换能器设备外部的接收器。本发明还涉及一种用于表示具有换能器设备的组件的簧管乐器的声音的系统、一种用于确定由具有换能器设备的组件的簧管乐器所演奏的音符的电子系统、以及一种练习演奏乐器的方法，包括使用换能器设备的组件。
摘要（英）：

With reference to FIG. 7a the present invention relates to transducer apparatus (200) for use with a reed instrument (201) having an air chamber (15) forming a resonant cavity whose resonance characteristics are controlled by opening and closing of tone holes (17A, 17B) connecting the air chamber to the exterior of the reed instrument. The transducer apparatus comprises attachment means (202) for releasably securing the transducer apparatus to a mouthpiece (201) of the reed instrument in place of a reed. A reed replacement section (203) has a housing with an abutment surface for abutting a surface part of the mouthpiece which would be abutted by a reed secured to the mouthpiece. An air passage extends through the housing of the reed replacement section (203) from an air inlet (211) through which a player of the instrument can blow to an air outlet (213) through which air blown by the player is delivered to atmosphere, without passing through the air chamber (15) within the reed instrument. A speaker (208) is supported by the housing and delivers sound to the air chamber (15). An air chamber microphone (209) is supported by the housing and receives sound in the air chamber (15). An electronic processing unit (204) has: an excitation unit (101) which produces an excitation signal for driving the speaker (208); a processor (102) for receiving a measurement signal produced by the microphone and for detecting from the measurement signal a musical note played by the instrument; a synthesizer (220) for generating an electronic signal embodying a musical note which corresponds to the detected musical note; and output means (103) for transmitting the musical note generated by the synthesizer to a receiver external of the transducer apparatus. The invention also relates to a system for representing the sounds of a reed instrument having the components of the transducer apparatus, to an electronic system for determining a musical note played by a reed instrument having the components of the transducer apparatus and to a method of practising playing of a reed instrument comprising use of the components of the transducer apparatus.
