  By the way, in the performance of a hand bell, a plurality of performers are each in charge of a hand bell that generates one or more pitches, and all the performers cooperate to perform music. That is, it is one of the pleasures of handbell performance that each performer not only demonstrates his performance skills but also shares a sense of unity that all performers cooperate.

  For this reason, for example, in rehabilitation for elderly people, music performance using handbells is proposed for the purpose of sharing the enjoyment of performing together, preventing dementia, and exerting a healing effect. Has been. In this case, it is not appropriate to use an expensive and heavy classic handbell. On the other hand, in order for all performers to share a sense of unity, a performance method peculiar to a handbell in which one performer is in charge of one or more pitches is indispensable. Even if the performance sound is reproduced, the above-mentioned purpose cannot be achieved.

  The present invention has been proposed in view of the above-described circumstances, and is an electronic handbell device that can be used inexpensively and easily, has the same operational feeling as a classic handbell, and can handle a full-fledged performance. And an electronic handbell device set.

  In order to achieve the above-described object, the electronic handbell device of the present invention has the following features. That is, the electronic handbell device of the present invention is an electronic handbell device that has a casting imitating a handbell, a clapper that can swing only in one axial direction, and a handle, and outputs a sound in response to a player's swinging motion. It is characterized by comprising a musical tone setting means, a hitting sensor, a swing strength detecting means, a musical tone signal generating means, and a musical tone generating means.

  The musical tone setting means is means capable of setting at least the pitch. The striking sensor is a sensor that is provided in either the casting or the clapper and detects the pressure when the clapper collides with the casting. The swing strength detecting means is means for detecting swing strength and collision timing in the player's swing motion based on the pressure signal output from the hit sensor. The tone signal generation means is a means for generating a tone signal according to the swing intensity and collision timing detected by the swing intensity detection means and the pitch set by the tone setting means. The tone generation means is means for generating a tone based on the tone generated by the tone signal generation means.

  In addition to the above-described configuration, the electronic handbell device of the present invention can be provided with a first pressure-sensitive sensor at an arbitrary position of casting. The tone signal generation means functions to stop generating the tone signal when the first pressure sensor detects pressure.

  In addition to the above-described configuration, the electronic handbell device of the present invention can be provided with a second pressure-sensitive sensor at an arbitrary position of casting. In this case, when the second pressure-sensitive sensor starts generating the tone signal while the pressure is being detected, the tone signal generating means generates a tone signal having a different form from that when the pressure is not being detected.

  Moreover, the electronic handbell device set of the present invention is an electronic handbell device having any one of the above-described configurations, and is characterized by comprising a plurality of electronic handbell devices set to different pitches. .

  In the electronic handbell device set having the above-described configuration, all pitches of the plurality of electronic handbell devices can be based on the same tuning type.

  Since the electronic handbell device of the present invention has a casting, a clapper and a handle imitating a handbell, it can perform the same playing method as a real handbell, but uses electronic components to generate sound. Therefore, the overall weight can be reduced. Generally, a hand bell is made of bronze, and in order to swing it, it requires gripping force and arm strength. However, the electronic handbell device of the present invention is configured with a musical sound generating means and a musical sound generating means by electronic components. Therefore, casting can be made using lightweight metal or plastic.

  Moreover, since the casting has a space inside, the electronic control device can be accommodated, so that the appearance can be the same as that of a real handbell, and the performer can perform without a sense of incongruity.

  Moreover, since the pitch can be set by the musical tone setting means, it is possible to set a pitch that matches the musical piece to be played for one electronic handbell device. For this reason, an electronic handbell device may be prepared according to the number of sounds of the music to be played. For example, if the number of pitches is five, it is sufficient to prepare five electronic handbell devices.

  Further, by providing the first pressure-sensitive sensor, it is possible to perform a ring performance technique (dumping), which is a handbell performance technique. The ring performance technique is a performance technique in which a handbell is swung downward to make a sound, the arm is turned in a vertical circle as it is, and finally the casting edge is applied to the chest to eliminate the sound.

  In addition, by providing the second pressure sensor, it is possible to perform a thumb performance (staccato performance) which is a performance method of a handbell. The thumb playing technique is a playing technique in which a handbell is tilted forward and a short sound is produced while the casting is held with a thumb.

<Outline of electronic handbell device>
As shown in FIGS. 1 and 3, the electronic handbell device 10 according to the embodiment of the present invention has a shape imitating a real handbell, and includes a casting 30, a clapper 40, and a handle 50. Sound is output according to the operation. That is, the electronic handbell device 10 includes a bell (casting 30), a pendulum (clapper 40) that can swing only in one axial direction inside the bell (casting 30), and an upper portion (blocking portion) of the bell (casting 30). The handle 50 is attached.

  As shown in FIGS. 1 and 3, the electronic handbell device 10 of the present embodiment can store the battery 60 and the electronic control device 20 inside a rod-like handle 50. Note that the battery 60 and the electronic control device 20 may be housed in the casting 30. As will be described in detail later, the electronic control device 20 is composed of an assembly of electronic components that cause the electronic handbell device 10 to function as a musical instrument, and includes various electronic components such as an IC chip mounted on a substrate (not shown). Yes.

  Further, inside the casting 30, a speaker which is the musical sound generating means 13 is accommodated. Instead of generating sound by the speaker, a sound may be generated by attaching a vibrator to the surface of the casting 30 and vibrating the casting by the vibrator.

  Further, the casting 30 includes an impact sensor 12 with which the impact portion 41 of the clapper 40 collides, and a first pressure sensor 14 and a second pressure sensor 15 for detecting pressure when the performer comes into contact. It is provided. The striking sensor 12 is provided on the inner surface of the casting, at positions (two places) where the striking portion 41 of the clapper 40 collides with the player's swinging motion. The first pressure-sensitive sensor 14 is provided, for example, in the vicinity of the opening of the casting 30 (opening edge), and the second pressure-sensitive sensor 15 is, for example, in the vicinity of the closing part (position where the player's thumb can reach). And provided on the surface of the casting 30.

  The clapper 40 is a member that swings only in one axial direction (linear direction). The clapper 40 according to the present embodiment swings according to the swinging motion of the player, and the striking portion 41 of the casting 30 is formed on the inner surface thereof. However, when the hitting portion 41 of the clapper 40 collides with the casting 30, the sound is not generated directly by vibrating the casting 30, but by the speaker which is the electronic control device 20 and the musical sound generating means 13. It is supposed to be generated.

  The handle 50 is a member for holding the electronic handbell device 10 in the hand when the performer swings the electronic handbell device 10. In the present embodiment, the handle 50 has a rod shape, but may be annular. The material is not particularly limited, but the annular handle 50 may be made of leather or synthetic resin string, or the rod-like handle 50 may be made of wooden or synthetic resin rod. Also good.

  As shown in FIGS. 1 and 3, the electronic handbell device 10 of the present embodiment includes the above-described casting 30, clapper 40, and handle 50 as structural components. Further, as main components for exhibiting the function as the electronic handbell device 10, as shown in FIG. 2, a musical tone setting means 23, a swing strength detecting means 24, a musical tone signal generating means 25, and a musical tone generating means. 13 and the impact sensor 12. Each means includes the electronic control device 20 and its associated devices. The electronic control unit 20 includes a control means 21 for comprehensively controlling each means, and a storage means 22 for storing programs necessary for generating musical sounds, musical sound data 22a, and the like.

  Further, in addition to these main components, a first pressure sensor 14, a second pressure sensor 15, and a volume operation unit 11 can be provided. In the following description, a program is a logic that can be stored in a RAM or the like and executed by hardware such as a CPU, so that not only software that exhibits the function but also an equivalent function can be achieved. It is a concept that includes a circuit.

<Musical sound setting means>
The musical tone setting means 23 is composed of a program capable of setting at least the pitch. The musical tone setting means 23 sets one pitch from at least a plurality of pitches for the electronic handbell device 10 used by each performer. Further, the musical tone setting means 23 may be configured to be able to set the volume, tone color, rhythm type (pure temperament, average temperament, classical rhythm, etc.) in addition to the pitch.

  In order to set the pitch by the musical tone setting means 23, for example, as shown in FIG. 3, a volume operation unit 11 (rotary knob, slider, etc.) is provided on the outer peripheral surface of the casting 30, and the volume operation unit 11 is provided. The pitch may be set by operating, for example, selecting a pitch name (C4, D4, E4, etc.). With this musical tone setting means 23, one electronic handbell device 10 can be set to a pitch desired by the performer.

  Although not shown, a display unit (for example, a liquid crystal display unit) for displaying a set value (for example, a pitch name) of the pitch according to the operation of the volume operation unit 11 is provided on the outer peripheral surface of the casting 30 or the like. May be. The same applies to a configuration in which settings such as volume, tone color, rhythm type (pure temperament, average temperament, classical rhythm, etc.) can be made in addition to the pitch.

  Note that the volume may be set using the volume operation unit 11. For example, when the performer swings the electronic handbell device 10 with a medium force (normal force), for example, The swing strength detected by the swing strength detection means 24 can be set as an intermediate value of the volume.

  In the setting of the timbre, by selecting a different timbre depending on the relationship between the fundamental tone and the overtone, it is possible to set a glossy sound, a dry crisp sound, or the like. For example, if you select a tone that has a high fundamental tone, a lower harmonic over 8 degrees, and a middle over 12 degrees, a glossy sound is set. If you select a tone with a large overtone, the sound will be dry and firm. Further, it is possible to set a human voice, an animal cry, etc. by setting the timbre.

<Swing intensity detection means>
The swing strength detection means 24 includes a program for detecting swing strength and collision timing in the player's swing motion based on the pressure signal output from the hit sensor 12. In a real handbell, the swing strength in the swing motion of the performer is reflected in the movement of the clapper 40, so the swing strength detecting means 24 is provided corresponding to this function. In the present embodiment, the collision pressure of the striking portion 41 is detected by the striking sensor 12 with which the striking portion 41 of the clapper 40 collides.

  The striking sensor 12 is composed of a pressure sensor attached to the inner surface of the casting 30 where the striking portion 41 of the clapper 40 collides, and a strength signal is detected by swinging a pressure signal generated when the striking portion 41 of the clapper 40 collides with the striking sensor 12. By inputting to 24, it is possible to detect the swing strength and collision timing in the player's swing motion. Further, since the clapper 40 swings in the uniaxial direction, the impact sensors 12 are provided at two locations so as to face each other on the inner surface of the casting 30.

  In the present embodiment, the impact sensor 12 is attached to the inner surface of the casting 30, but the impact sensor 12 may be attached to the impact portion 41. Also in this case, since the clapper 40 swings in one axis direction, the impact sensor 12 is provided at both end portions (two locations) of the impact portion 41.

  The hit sensor 14 is constituted by two switches (first switch and second switch) that are turned on from the off state with a time difference when the casting 30 and the hitting portion 41 of the clapper 40 collide, for example. May be. In this case, when the casting 30 and the hitting portion 41 of the clapper 40 collide, first, the first switch is turned on, and then the second switch is turned on.

  The impact sensor 14 having such a configuration can detect the strength of the collision based on the time from when the first switch is turned on to when the second switch is turned on. That is, since the speed of swing of the clapper 40 is proportional to the strength of the collision, the stronger the collision strength, the longer the time from when the first switch is turned on to when the second switch is turned on. It will be short. The timing at which the casting 30 and the hitting portion 41 of the clapper 40 collide may be the timing at which the second switch is turned on.

  Note that the electronic handbell device 10 of the present embodiment does not actually generate a sound by causing the striking portion 41 of the clapper 40 to collide with the inner surface of the casting 30. Therefore, it is preferable that at least one of the casting 30 and the striking portion 41 is formed of an elastic member (for example, rubber or elastic plastic) so that a collision sound is not generated even when the striking portion 41 collides with the casting 30.

  An acceleration sensor may be used to detect the swing strength. Although not shown, the acceleration sensor is a sensor attached to the clapper 40, and the clapper 40 swings only in one axial direction (linear direction). Therefore, by detecting the acceleration in the swing direction, the swing sensor in the swing motion of the player is detected. The intensity can be detected. Further, the collision timing can be detected by the change in acceleration.

<Musical signal generation means>
The musical sound signal generating means 25 is composed of a program for generating a musical sound signal according to the swing intensity and collision timing detected by the swing intensity detecting means 24 and the pitch set by the musical sound setting means 23. That is, the musical sound signal generating means 25 generates sound generation data using the sound source (musical sound data 22a) based on the detected swing strength and the set pitch. Various sound sources can be used. For example, a MIDI standard sound source, a sampling sound source, a PCM sound source, and the like can be used.

  The musical tone signal generating means 25 can change not only the volume but also the timbre based on the swing strength. For example, when the electronic handbell device 10 is shaken lightly, a sound like a glasswork can be generated, and when vigorously shaken, a sound like a bell can be generated.

<Musical sound generation means>
The tone generation means 13 comprises an electronic circuit for generating the tone generated by the tone signal generation means 25. That is, the musical sound generating means 13 is a means for actually generating a handbell sound. In this embodiment, the speaker functions as the musical sound generating means 13. Further, as described above, a vibrator that vibrates the casting 30 may function as the musical sound generating means 13.

  When the musical sound generating means 13 is constituted by a speaker, the sound generation data received from the musical sound signal generating means 25 is amplified by an amplifier function to generate sound from the speaker. Further, when the musical sound generating means 13 is constituted by a vibrator, the casting 30 itself serves as a speaker, and generates a sound by vibration of the vibrator based on the pronunciation data.

<First pressure sensitive sensor>
The first pressure sensor 14 is a pressure sensor provided at an arbitrary position of the casting 30. When the first pressure sensitive sensor 14 is provided, the musical sound signal generating means 25 stops generating the musical sound signal when the first pressure sensitive sensor 14 detects the pressure. The first pressure-sensitive sensor 14 is a sensor for performing a ring performance method (dump), which is a handbell performance method. As described above, the ring performance method is a performance method in which the handbell is shaken downward to make a sound, the arm is turned as if a circle is drawn as it is, and finally the edge of the casting 30 is applied to the chest to eliminate the sound. It is. Therefore, in order to produce the same operational feeling as a real handbell, it is preferable to attach the first pressure sensor 14 to the opening edge of the casting 30. If it can be recognized, it may be attached to another position.

  When the generation of the musical sound signal is stopped, for example, the volume may be gradually attenuated, or the volume may be rapidly attenuated. In order to attenuate the volume, for example, a method for controlling the output waveform of a musical sound signal to attenuate the volume, a musical signal with a general attenuation waveform and a rapid attenuation waveform is prepared in advance, and these are switched and output. There is a method of attenuating the sound volume.

<Second pressure sensitive sensor>
The second pressure sensor 15 is a pressure sensor provided at an arbitrary position of the casting 30. In order to achieve the same operational feeling as a real handbell, the second pressure sensor 15 is provided on the outer peripheral surface of the casting 30 and in the vicinity of the closing portion (for example, the position where the player's thumb can reach). It is preferable. In the case where the second pressure sensor 15 is provided, the second pressure sensor 15 is used when the tone signal generator 25 starts generating the tone signal while the second pressure sensor 15 is detecting the pressure. Generates a musical sound signal having a mode different from that when the pressure is not being detected. More specifically, in order to simulate a handbell sound by staccato performance, the musical sound signal generating means 25 controls the decay time after the sound rise to be shorter than usual, or stores it in advance. A dedicated waveform data obtained by sampling the staccato performance of the hand bell may be read out. The second pressure-sensitive sensor 15 is a sensor for performing a thumb performance (staccato performance), which is a handbell performance method. As described above, the thumb playing method is a playing method in which the handbell is tilted forward and a short sound is produced while the casting 30 is held with the thumb. A method for attenuating the musical sound signal may be the same as that of the first pressure sensor 14.

<Electronic handbell device set>
As shown in FIG. 4, an electronic handbell device 10 having any of the above-described configurations, and having a plurality of electronic handbell devices 10 set to different pitches, constitutes an electronic handbell device set. Can do. In this case, all the pitches of the plurality of electronic handbell devices are based on the same tuning type.

<Performance using an electronic handbell device>
In order to perform a performance using the electronic handbell device 10 according to the embodiment of the present invention, the required number (for example, five) of electronic devices according to the pitch of the musical composition to be performed (for example, five pitches). A handbell device 10 is prepared. Then, a pitch necessary for performance is assigned to each electronic handbell device 10. For example, when playing the song “Tulip”, the performance can be performed with five pitches of de, les, mi, so, and la. Also, when playing the song “Butterfly”, the performance can be performed with five pitches of de, les, mi, fa and so.

  Then, each performer is in charge of the electronic handbell device 10 set to the pitch in charge. At this time, one player may be in charge of two or more electronic handbell devices 10. When the person in charge of each electronic handbell device 10 is determined, for example, using a karaoke device or the like, the accompaniment sound is played, the score is displayed on the display screen of the display device, or the person in charge of the performance is designated. be able to.

<Other embodiments>
In addition to the above-described configuration, the electronic handbell device 10 of the present invention has a light emitting device (for example, LED) or a vibration device (for example, an LED) or a vibration device (for indicating the performance timing to the performer at an appropriate position of the casting 30 or the clapper 40. For example, it is possible to provide a vibration motor. For example, the light emitting device or the vibration device acquires sounding timing data of each pitch from music data used for performance in a karaoke device or the like, and lights the light emitting device or vibrates the vibration device based on the sounding timing data. I will let you. Note that the lighting timing of the light emitting device and the vibration timing of the vibration device are preferably earlier than the sound generation timing of each pitch. For example, blinking or intermittent vibration is started 3 seconds before the sound generation timing, and the lighting timing or continuous vibration state is set simultaneously with the sound generation timing, so that the performer can appropriately grasp the performance timing.

  Further, an earphone terminal which is an external audio output terminal can be provided at an appropriate position of the casting 30 or the clapper 40. When the earphone terminal is provided, by attaching headphones or the like to the earphone terminal, the sound is output only from the headphones without being output to the outside, so that the sound of the electronic handbell device 10 is annoying to others. It will never be.

  In addition, a fixing mechanism for fixing the electronic handbell device 10 to a foot (a knee or an ankle), an arm, or the like can be provided at an appropriate position of the casting 30 or the clapper 40. This fixing mechanism can be made of, for example, a belt having a buckle, a rubber band, a belt with a double-sided fastener, or the like. When such a fixing mechanism is provided, performance can be performed using not only hands but also feet, and variations in performance can be increased. Furthermore, even a person who cannot sufficiently perform hand movements can enjoy the performance of the electronic handbell device 10.
