摘要： PROBLEM TO BE SOLVED: To provide an actuator for a woodwind instrument performance and a woodwind instrument player, by which timbre very close to that by a human performance can be obtained. SOLUTION: When compressed air is blown in an artificial mouth 19, a reed 17 self-vibrates with a compressed air flow and then goes into behavior that is almost in a playing state of a real woodwind instrument. At the same time, a piezoelectric vibrator 23, stuck on the reed 17 vibrates corresponding to an excitation signal, but the piezoelectric vibrator 23 is compact and lightweight and has weak mechanical characteristics, so that self-vibrations of the reed 17 are disturbed less. Furthermore, the piezoelectric vibrator 23 is easily influenced by a tube resonance frequency of a wind instrument, so vibrations of non-resonance frequency are attenuated with sound waves reflected by the tube, but vibrations of resonance frequency are amplified by the tube. Thus, vibrations corresponding to resonance of the tube are obtained, and then the reed 17 behaves almost in the playing state of the real wind instrument whose reed 17 self-oscillates, despite its being driven by an electrical signal.

摘要： PROBLEM TO BE SOLVED: To provide a technology for detecting manipulation by a wind instrument player, without having to install a sensor provided in a manipulation element, such as, a piston valve. SOLUTION: The wind instrument player blows expiratory air into a second mouthpiece so as to play a wind instrument. The second mouthpiece 22 is different from a mouthpiece 21 actually mounted to the wind instrument 2. An ultrasonic actuator 161 for generating stationary ultrasonic waves is mounted to a flare 25 of the wind instrument 2. An ultrasonic sensor 162 for detecting the ultrasonic waves is mounted to a throat of the mouthpiece 21. A sensor 226 for detecting a sound pressure generated by the expiratory air blown by the wind instrument player is provided in the second mouthpiece 22. Since a sound generating actuator 11 is driven, based on a detection result from the sensor 226, sound waves are generated within the mouthpiece 21, and a performance sound is emitted from the wind instrument 2. A back pressure actuator 228 is driven, based on the detection results from the sensor 226 and the ultrasonic sensor 162. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a drum head which has durability and sound-deadening qualities and with which an excellent beating feeling can be obtained. SOLUTION: The drum head 30 is structured by stacking a film of polyethylene terephthalate in three layers, which are merely superposed one over another. Further, the drum head 30 has many through holes of 0.5 to 3 mm in diameter and is 20 to 50% in numerical aperture. When a player beats the drum head 30 with a stick, the air compressed in the percussion instrument 1 as the drum head is beaten is discharged from the percussion instrument through a plurality of through holes that the drum head 30 has. As the air compressed in the percussion instrument 1 is discharged from the percussion instrument 1, propagation of vibrations of the drum head 30 to air is reduced, so that a beat sound is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a playing assist device that assists a player in playing so that even if the player is unskilled in playing, the player can properly play a musical instrument by himself. SOLUTION: When the player puts an embouchure detection sensor 11 on the lips 4, forms lip reeds, and blows breath in, an embouchure and breathing pressure at this time are detected by the embouchure detection sensor 11 and a breathing pressure sensor 12. Consequently, a breathing pressure detection part 15 detects the breathing pressure, and a breathing pressure correction part 16 generates a breathing pressure auxiliary signal, by taking recommended data into account by a quantity that corresponds to the degree (r) of participation. A breathing pressure actuator driving part 20 drives a breathing pressure actuator 21 according to the breathing pressure auxiliary signal, and consequently compressed air flows in a slide of a trumpet 2 by a quantity corresponding to the breathing pressure auxiliary signal. An embouchure correction part 14, however, generates an embouchure auxiliary signal, by taking recommended data into account by a quantity corresponding to the degree (r) of participation and an embouchure actuator 18 is driven according to the signal.

摘要： PROBLEM TO BE SOLVED: To provide an actuator for a brass instrument performance and a brass instrument player, which has small electric power consumption and by which timbre very close to that by human's lip reeds can be obtained. SOLUTION: When diaphragms 13a and 13b are vibrated, while compressed air is blown in through a compressed air insertion hole 20, the boundary part between the diaphragms 13a and 13b flexes toward a mouthpiece with the pressure of the compressed air to form a gap. Furthermore, a gap by vibrations is formed, even at the boundary part between the diaphragms 13a and 13b. The compressed air is sent in the brass instrument through the gaps which are thus formed. A sound wave, generated by the diaphragms 13a and 13b, is reflected by a bell atop of the brass instrument to return to the diaphragms 13a and 13b. Since the diaphragms 13a and 13b vibrate at a frequency, matching a resonance frequency of the brass instrument, the sound wave resonates with the reflected wave to amplify the sound pressure in the sound wave in the tube, natural and loud sound volume resembling that of a brass instrument is obtained. Thus, the sound volume that utilizes resonance of the brass instrument is produced. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：为了提供一种用于铜管乐器性能的执行机构和一种具有小功耗的铜管乐器演奏器，并且可以获得与人的嘴唇非常接近的音色。解决方案：当隔膜13a和13b振动时，当压缩空气通过压缩空气插入孔20吹入时，隔膜13a和13b之间的边界部分以压缩空气的压力朝向接口件弯曲，以形成间隙。此外，即使在膜片13a和13b之间的边界部分也形成有通过振动的间隙。压缩空气通过这样形成的间隙在铜管乐器中送出。由隔膜13a和13b产生的声波被铜管乐器的顶部的钟形反射回到隔膜13a和13b。由于膜片13a和13b以与铜管乐器的共振频率相匹配的频率振动，所以声波与反射波共振以放大管中的声波中的声压，自然和大声音量类似于铜管乐器。因此，产生利用铜管乐器的共振的音量。版权所有（C）2007，JPO＆INPIT
