Abstract

The electronic musical instrument 4 includes a first cymbal 11 that contains a metal. The first cymbal 11 is conductive. Furthermore, the electronic musical instrument 4 includes a capacitance-type touch sensor 43, and the first cymbal 11 is used as a touch electrode of the touch sensor 43. Therefore, when a performer having capacitance touches the first cymbal 11, the ground-to-ground capacitance of the first cymbal 11 changes, and a signal corresponding to this change in ground-to-ground capacitance is output from the touch sensor 43. Therefore, when a performer touches the first cymbal 11 in the same way as when muting a conventional cymbal, a signal indicating mute can be output from the touch sensor 43.

Description

[Technical field]

[0001] The present invention relates to an electronic cymbal that is connected to a sound source device to generate striking sounds. The present invention also relates to an electronic cymbal set equipped with such an electronic cymbal and an electronic hi-hat cymbal. [Background technology]

[0002] Patent Document 1 relates to an electronic cymbal pad that can be used as an electronic cymbal. A vibration sensor is attached to the electronic cymbal pad of Patent Document 1. The vibration sensor detects vibrations generated by the electronic cymbal pad when the electronic cymbal pad is struck by a player. The signal from the vibration sensor is used to obtain the striking position on the electronic cymbal pad, the striking time, the striking strength, etc.

[0003] The electronic cymbal pad of Patent Document 1 is also equipped with a membrane switch. The membrane switch is a bow-shaped sheet-like touch sensor. When a player touches the membrane switch, the membrane switch outputs a signal indicating a mute operation. The membrane switch is attached to a portion of the circumferential edge of the electronic cymbal pad. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2019-191406 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the technology of Patent Document 1, when muting an electronic cymbal, the player must touch the area on the electronic cymbal where the membrane switch is fixed. Therefore, when muting the cymbal, it may be necessary to check the area on the electronic cymbal where the membrane switch is fixed. Therefore, when muting the cymbal, the feeling of playing that the player feels may be impaired.

[0006] In view of the above circumstances, an object of the present invention is to provide an electronic cymbal that can output a signal indicating muting by the same operation as when muting a conventional cymbal. Also, an object of the present invention is to provide an electronic cymbal set and an electronic hi-hat cymbal equipped with such an electronic cymbal and a control device. [Means for solving the problem]

[0007] In order to overcome the above problems, an electronic musical instrument according to the present invention includes a first cymbal containing a metal and a capacitive touch sensor including a touch electrode, wherein the first cymbal is conductive and the touch electrode is the first cymbal.

[0008] The electronic musical instrument of the present invention includes a first cymbal containing a metal. Therefore, when a player strikes the first cymbal, the player can obtain the same playing feeling as when striking a conventional cymbal. Furthermore, this electronic musical instrument includes a capacitance-type touch sensor, and the first cymbal is used as a touch electrode of the touch sensor. Therefore, when a player having capacitance touches the first cymbal, the ground-to-ground capacitance of the first cymbal changes, and a signal corresponding to the change in ground-to-ground capacitance is output from the touch sensor. Therefore, when a player touches the first cymbal in the same way as when muting an actual cymbal, a signal indicating muting can be output from the touch sensor. This eliminates the need for the player to check the area that the player is required to touch when muting the cymbal. Therefore, it is possible to prevent or suppress the loss of playing feeling of a player playing the electronic musical instrument when muting the cymbal.

[0009] In the present invention, it is preferable to include a first vibration sensor configured to detect the vibration of the first cymbal and a second vibration sensor configured to detect the vibration of the first cymbal on the outer circumferential side of the first vibration sensor, the first vibration sensor being arranged to overlap with the bell of the first cymbal when viewed in the up-down direction, and the second vibration sensor being arranged to overlap with a region of the bow of the first cymbal that is closer to the bell than the edge. In this way, the electronic musical instrument includes two vibration sensors at different positions in the radial direction of the first cymbal. Therefore, it is easy to obtain the striking position on the first cymbal based on the signals output from each of the two vibration sensors.

[0010] The present invention may include a substrate on which a circuit part of a touch sensor is formed, a resin holder supporting the substrate and the first vibration sensor, and a plurality of headed screws for fixing the holder to the underside of the first cymbal, the first cymbal includes a central hole, the holder includes a cylindrical portion inserted into the central hole, and a plurality of bosses arranged in an annular shape on the outer periphery of the cylindrical portion, the outer periphery of the cylindrical portion contacts the inner wall surface of the central hole of the first cymbal, and a screw hole capable of engaging with the headed screw is provided on the upper surface of each of the bosses, and the holder is fixed to the first cymbal by inserting each of the headed screws from the top to the bottom into the first cymbal and screwing them into the screw holes of the bosses. This allows the holder supporting the substrate and the first vibration sensor to be attached to the first cymbal.

[0011] The present invention may include a substrate on which a circuit part of a touch sensor is formed, a resin holder that supports the substrate and the first vibration sensor, and a plurality of headed screws for fixing the holder to the underside of a first cymbal, the first cymbal includes a central hole, the holder includes a cylindrical part that is inserted into the central hole, and a plurality of bosses arranged in an annular shape on the outer periphery of the cylindrical part, the outer periphery of the cylindrical part contacts the inner wall surface of the central hole of the first cymbal, and a screw hole that can be engaged with the headed screw is provided on the upper surface of each of the bosses, and the holder is fixed to the first cymbal by inserting each of the headed screws from the top to the bottom into the first cymbal and screwing them into each of the screw holes of the bosses. This makes it easy to use the first cymbal as a touch electrode by electrically connecting the circuit part of the touch sensor and the first cymbal. Furthermore, since the headed screws used to fix the holder to the first cymbal are conductive, the circuit part of the touch sensor and the first cymbal are electrically connected via the terminal and the headed screws. This makes it possible to ensure a connection between the circuitry of the touch sensor and the first cymbal.

[0012] In the present invention, when the holder is fixed to the first cymbal, the boss may surround the bell on the outer periphery of the bell. In this way, the holder is fixed to the first cymbal in a state of contact with the opening edge of the center hole of the first cymbal and the outer periphery of the bell. Therefore, when the first cymbal is struck, the holder functions as a damper for quickly attenuating the vibration of the bell. Since the first cymbal is made of metal or contains metal, the vibration caused by the strike is likely to undulate, and the amplitude repeatedly increases and decreases. Therefore, there is a problem that the strike time, which is the time of the maximum amplitude, is likely to be erroneously detected from the amplitude of the first cymbal. Regarding such a problem, when the holder functions as a damper for quickly attenuating the vibration of the bell, it becomes easy to obtain the strike time based on the signal from the first vibration sensor.

[0013] In the present invention, the holder may include a plurality of first bosses arranged in a ring shape as bosses, and a plurality of second bosses arranged in a ring shape between the first bosses and the tubular portion, and the holder is fixed to the first cymbal by screwing each of the headed screws into the screw holes of the first bosses or screwing each of the headed screws into the screw holes of the second bosses. In this way, when the holder is fixed to the first cymbal, it is possible to select the boss into which the headed screws are screwed between the first boss and the second boss positioned on its inner periphery. Therefore, for example, when there are two types of first cymbals with different radial sizes as the first cymbals, the two types of first cymbals can share one first holder. In this case, when the holder is fixed to the first cymbal by screwing each of the headed screws into the screw holes of the first bosses, the first boss can be positioned on the outer periphery of the bell, and the second boss can overlap with the bell when viewed from the top and bottom. Furthermore, when the holder is fixed to the first cymbal by screwing each of the headed screws into each of the screw holes of the second boss, the first boss and the second boss can be positioned on the outer periphery of the bell. In this way, when one holder is used with two types of first cymbals having different radial sizes, the bosses can be positioned on the outer periphery of the bell.

[0014] In the present invention, when the holder is fixed to the first cymbal, the boss may surround the central hole of the bell at a position closer to the central hole than the bow, and the holder does not have a portion that contacts the first cymbal on the outer periphery side of the boss. As a result, the holder is fixed to the first cymbal at a position close to the center of the first cymbal. Therefore, the sound generated when the first cymbal is struck is closer to the sound when an actual cymbal is struck, compared to when the holder contacts the first cymbal on the outer periphery side of the bell. Therefore, the playing feeling when the player strikes the first cymbal can be made closer to the playing feeling when a conventional cymbal is struck. Meanwhile, the holder contacts the first cymbal at a position close to the center of the first cymbal and the bell within the opening edge of the central hole of the first cymbal. Therefore, the holder fixed to the first cymbal functions as a damper for quickly attenuating the vibration of the bell. Since the first cymbal is made of metal or contains metal, the vibration generated by striking the cymbal tends to generate undulations, and the amplitude repeatedly increases and decreases. Therefore, there is a problem that the striking time, which is the time of the maximum amplitude, tends to be erroneously detected. Regarding such a problem, when the holder functions as a damper for quickly attenuating the vibration of the bell, it becomes easy to obtain the striking time based on the signal from the first vibration sensor.

[0015] The present invention may include a substrate on which a circuit part of a touch sensor is formed, a resin holder supporting the substrate and a first vibration sensor, a nut for fixing the holder to a first cymbal, a lead wire for electrically connecting the circuit part of the touch sensor and the first cymbal, and a conductive member connected to the lead wire, the first cymbal includes a central hole, the holder includes a tube part inserted into the central hole, an annular plate part expanding from the bottom end of the tube part toward the outer periphery, and a male thread provided on the outer periphery of the tube part, the annular plate part includes an attachment part for arranging the conductive member, the nut is screwed onto the male thread of the tube part protruding upward from the first cymbal and abuts against the opening edge of the central hole of the first cymbal, the conductive member is sandwiched between the attachment part and the opening edge, and the holder does not have a portion that contacts the first cymbal further on the outer periphery side than the annular plate part. As a result, the holder is fixed to the first cymbal at a position close to the center of the first cymbal. Therefore, the sound generated when the first cymbal is struck is closer to the sound generated when an actual cymbal is struck, compared to when the boss for fixing the holder to the first cymbal surrounds the bell on the outer periphery side of the bell. This makes it easier for the player to obtain the same playing sensation as when striking an actual cymbal. Meanwhile, the holder is fixed to the bell by a nut having a relatively large contact area with the first cymbal. Therefore, the holder fixed to the first cymbal functions as a damper for quickly attenuating the vibration of the bell. Since the first cymbal is made of metal or contains metal, the vibration generated by striking is likely to generate swells, and the amplitude repeatedly increases and decreases. Therefore, there is a problem that the striking time, which is the time of the maximum amplitude, tends to be erroneously detected. Regarding such a problem, when the holder functions as a damper for quickly attenuating the vibration of the bell, it becomes easy to obtain the striking time based on the signal from the first vibration sensor. By screwing the nut into the cylindrical portion, the conductive member is sandwiched between the first cymbal and the mounting portion. This allows the circuit section of the touch sensor to be connected to the first cymbal via the lead wire and the conductive member, making it easy to use the first cymbal as a touch electrode of the touch sensor.

[0016] The present invention may include a second holder supporting the second vibration sensor and two second headed screws for fixing the second holder to the underside of the first cymbal, the second holder including a sensor support portion supporting the second vibration sensor, a first screw hole provided on one side of the sensor support portion, and a second screw hole provided on the opposite side of the first screw hole of the sensor support portion, the second holder being fixed to the first cymbal by inserting each of the second headed screws from the top to the bottom into the first cymbal and screwing into the first screw hole and the second screw hole, and when the second holder is fixed to the first cymbal, the two second headed screws are arranged in the radial direction of the first cymbal. This makes it easier for the second vibration sensor to detect the vibration of the first cymbal. In other words, when the first cymbal is struck, the vibration is propagated in the circumferential direction as a bow swell. Therefore, when the two headed screws for fixing the second holder are arranged in the circumferential direction of the first cymbal when the second holder is fixed to the first cymbal, the undulation of the bow tends to be hindered by the two headed screws and the second holder, and the amplitude of the vibration caused by the strike tends to be reduced. In contrast, when the two headed screws for fixing the second holder are arranged in the radial direction of the first cymbal, it is possible to prevent the undulation of the bow propagating in the circumferential direction from being hindered by the two headed screws and the second holder. In this way, the reduction in the amplitude of the vibration caused by the strike can be suppressed. Therefore, it becomes easier to obtain the amplitude of the vibration corresponding to the strength of the strike by the second vibration sensor.

[0017] It should be noted that an electronic hi-hat cymbal can be constructed by supporting the first and second cymbals on a commercially available hi-hat stand and arranging the second cymbal coaxially below the first cymbal. When the first and second cymbals are used as an electronic hi-hat cymbal, the vertical separation distance between the first and second cymbals is changed by stepping on the pedal of the hi-hat stand. Therefore, in order to reproduce a striking sound that changes according to the change in separation distance, it is necessary to have a distance sensor that outputs a signal to obtain the separation distance between the first and second cymbals.

[0018] For this purpose, the present invention may include a substrate on which a circuit part of a touch sensor is formed, a resin holder that supports the substrate and a first vibration sensor, the holder being fixed to the back surface of the first cymbal, a second cymbal containing a metal that is arranged coaxially below the first cymbal, and a distance sensor that is supported on the holder and outputs a signal corresponding to the separation distance between the first cymbal and the second cymbal in the up-down direction, the second cymbal being conductive, the distance sensor including an oscillator circuit having a coil with an opening facing in the up-down direction, the distance sensor outputting a signal oscillated by the oscillator circuit, the coil being fixed to the holder and positioned below the first cymbal. It should be noted here that the second cymbal contains a metal that is conductive. Thus, the frequency and amplitude of the signal oscillated by the oscillator circuit change depending on the separation distance between the first cymbal and the second cymbal. Thus, a signal corresponding to the separation distance between the first cymbal and the second cymbal can be output from the distance sensor. Furthermore, since the coil is positioned below the first cymbal, the distance between the first and second cymbals can be detected with high accuracy.

[0019] Furthermore, the present invention may include a substrate on which a circuit part of a touch sensor is formed, a resin holder that supports the substrate and the first vibration sensor, the holder being fixed to the back surface of the first cymbal, a second cymbal that is arranged coaxially below the first cymbal, and a distance sensor that is supported on the holder and outputs a signal corresponding to the distance between the first cymbal and the second cymbal in the vertical direction, the second cymbal including a conductive metal member, the distance sensor including an oscillator circuit having a coil with an opening facing in the vertical direction, the distance sensor outputting a signal oscillated by the oscillator circuit, the coil being fixed to the holder and positioned below the first cymbal. In this way, regardless of the material of the second cymbal, a signal corresponding to the distance between the first cymbal and the second cymbal can also be output from the distance sensor. Furthermore, since the coil is positioned below the first cymbal, the distance between the first cymbal and the second cymbal can be detected with high accuracy.

[0020] The present invention may include a cable and a cable guide, the second cymbal including a wiring hole provided in a portion of the circumferential direction and opened so as to penetrate in the vertical direction, the substrate including a connector electrically connected to the touch sensor, the first vibration sensor, the second vibration sensor, and the distance sensor, the cable being removably connected to the connector when inserted through the wiring hole from the underside of the second cymbal, and the cable guide being fixed to the second cymbal when inserted through the wiring hole, and including a pair of opposing portions facing the cable from both sides in the circumferential direction at a position away from the second cymbal toward the lower side.

[0021] In this way, signals from the touch sensor, the first vibration sensor, the second vibration sensor, and the distance sensor can be taken out to the outside via the cable. Furthermore, the upper end of the cable is connected to the connector of the board supported by the holder, extends downward from the connector, and passes through a wiring hole provided in the second cymbal. Furthermore, the cable is in a state where its circumferential displacement is adjusted by a pair of opposing parts of the cable guide fixed to the second cymbal. Therefore, for example, when the first cymbal supported by the hi-hat stand is struck and attempts to rotate in the circumferential direction, the pair of opposing parts of the cable guide interfere with the cable from the circumferential direction, restricting the relative rotation of the first cymbal and the second cymbal. Furthermore, the cable inserted through the second cymbal extends downward and is routed while in contact with the floor surface, etc., so that the movement of the cable itself is restricted by the floor surface. As a result, the first cymbal and the second cymbal are prevented from rotating excessively. By preventing or suppressing excessive rotation of the first cymbal, it is possible to prevent or suppress excessive circumferential displacement of the positions of the first vibration sensor and the second vibration sensor attached to the first cymbal, thereby suppressing excessive changes in the levels of the signals from the first vibration sensor and the second vibration sensor caused by excessive changes in the distance between the striking position of the player and the first vibration sensor and the second vibration sensor due to the rotation of the first cymbal.

[0022] In the present invention, the second cymbal may have an outer diameter smaller than that of the first cymbal, and the outer periphery of the upper surface of the second cymbal may be covered with a shock absorbing member. This makes it possible to prevent or suppress damage to the first cymbal when the first cymbal made of metal or containing metal and the second cymbal made of metal or containing metal come into contact with each other. Furthermore, since the outer periphery of the upper surface of the second cymbal is covered with a shock absorbing member, a buzzing sound generated when the first cymbal and the second cymbal are played with an opening that allows slight contact between them is not transmitted to the first vibration sensor and the second vibration sensor.

[0023] Next, a cymbal set according to the present invention includes the above-mentioned electronic musical instrument and a control device connected to the electronic musical instrument via a cable, and the control device includes an attack signal generating unit configured to generate an attack signal indicating the time of a strike based on an output from the first vibration sensor, a dynamic signal generating unit configured to generate a dynamic signal indicating the strength of the strike based on the output from the second vibration sensor, a strike position signal generating unit configured to generate a strike position signal indicating a strike position on the first cymbal based on the output from the first vibration sensor and the output from the second vibration sensor, a mute signal generating unit configured to generate a mute signal indicating mute based on the output from the touch sensor, a separation distance signal generating unit configured to generate a separation distance signal indicating a separation distance based on the output from the distance sensor, and an output unit configured to output the attack signal, the dynamic signal, the strike position signal, the mute signal, and the separation distance signal to the outside.

[0024] According to the present invention, a control device connected to an electronic musical instrument via a cable generates an attack signal indicating a time point of a strike based on an output from a first vibration sensor. Since the first cymbal contains metal, the vibration generated by the strike is likely to generate swells, and the amplitude repeatedly increases and decreases. Therefore, there may be a problem that an attack signal having a time point of maximum amplitude acquired as the time point of the strike tends to be erroneously detected. Regarding such a problem, a signal from the first vibration sensor arranged at a position overlapping with the bell of the first cymbal has fewer low-frequency band components than a signal from the second vibration sensor arranged at a position overlapping with the bow, and its amplitude tends to attenuate with time. Furthermore, the amplitude of the vibration of the bell is easily attenuated by a holder fixed to the first cymbal. Therefore, by acquiring an attack signal based on a signal from the first vibration sensor, it is possible to prevent or suppress the attack signal generation unit from erroneously detecting the attack signal. Furthermore, since the signal from the second vibration sensor arranged at a position overlapping with the bow has more low frequency band components than the signal from the first vibration sensor arranged at a position overlapping with the bell, it is easier to obtain the amplitude of vibration corresponding to the strength of the strike. Therefore, the dynamic signal generating unit can easily generate a dynamic signal indicating the strength of the strike based on the signal from the second vibration sensor. Furthermore, the control device includes an output unit for outputting the attack signal, the dynamic signal, the strike position, the mute signal, and the separation distance signal generated based on the output from each of the sensors of the electronic cymbal. Therefore, by inputting the signal from the output unit of the control device to the sound source device, a strike sound corresponding to the strike of the electronic cymbal can be generated from the sound source device.

[0025] Next, an electronic hi-hat cymbal according to the present invention includes the above-mentioned electronic cymbal set and a hi-hat stand, the hi-hat stand including a first support part that supports the first cymbal, a second support part that supports the second cymbal, and a lifting mechanism that raises and lowers the first support part, and when the first cymbal supported by the first support part is raised and lowered up and down, the coil moves together with the first cymbal, below the first cymbal.

[0027] Hereinafter, an electronic cymbal, an electronic cymbal set, and an electronic hi-hat cymbal according to embodiments of the present invention will be described with reference to the accompanying drawings. (First embodiment) FIG. 1 is an exemplary diagram of an electronic hi-hat cymbal. FIG. 2 is a perspective view of the electronic cymbal when viewed from above. FIG. 3 is a perspective view of the electronic cymbal when viewed from below. FIG. 4 is a cross-sectional view of the electronic cymbal. The electronic hi-hat cymbal 1 of this embodiment includes an electronic musical instrument 4 supported by a commercially available hi-hat stand 2, and a module 6 (control device) electrically connected to the electronic musical instrument 4 via a cable 5. The electronic musical instrument 4, the cable 5, and the module 6 constitute a cymbal set 3. In this embodiment, the electronic musical instrument 4 includes a first cymbal unit 7 and a second cymbal unit 8.

[0028] The first cymbal unit 7 includes a first cymbal 11 made of or containing a metal. The second cymbal unit 8 includes a second cymbal 12 made of or containing a metal. The first cymbal 11 and the second cymbal 12 are both conductive (e.g., conductive, etc.). As shown in Figs. 2 and 4, the center portion of the first cymbal 11 is higher than the outer periphery. As shown in Figs. 3 and 4, the center portion of the second cymbal 12 is lower than the outer periphery. As shown in Fig. 4, the outer dimensions of the first cymbal 11 are larger than those of the second cymbal 12. It should be noted that the first cymbal 11 and the second cymbal 12 may be provided with a number of small holes 15 drilled in the vertical direction across the entire surface thereof in order to suppress the volume of the striking sound when the first cymbal 11 is struck.

[0029] As shown in Fig. 1, the first cymbal unit 7 and the second cymbal unit 8 are each supported by the hi-hat stand 2. This positions the second cymbal 12 coaxially below the first cymbal 11. In the following description, the direction along the central axis L of the first cymbal unit 7 and the second cymbal unit 8 is referred to as the up-down direction X. The side along this axial direction on which the first cymbal unit 7 is positioned is referred to as the upper side X1, and the opposite side is referred to as the lower side X2.

[0030] Here, the hi-hat stand 2 includes a first support part 21 that supports the first cymbal 11, a second support part 22 that supports the second cymbal 12, and a lifting mechanism 23 that raises and lowers the first support part 21. The lifting mechanism 23 includes an extension rod 24, a hollow shaft 25, and a leg part 26 that supports the hollow shaft 25 in an upright position. The extension rod 24 is inserted into the hollow shaft 25 in a manner that allows it to move in the vertical direction X, and is biased to a specified upper position by a spring (not shown). The first support part 21 is provided relative to the extension rod 24. The first cymbal unit 7 is rotatably supported by the first support part 21, and the extension rod 24 is inserted through its central hole 11a. The second support part 22 is provided relative to the hollow shaft 25. The second cymbal 12 is supported by the second support part 22 so as to be rotatable and tiltable, and a hollow shaft 25 is inserted through its central hole 12a. The central axis L of the first cymbal unit 7 and the second cymbal unit 8 coincides with the axis of the extension rod 24 and the hollow shaft 25.

[0031] The lifting mechanism 23 includes a pedal section 27 that is stepped on, and a link mechanism 28 that lifts and lowers the extension rod 24 in conjunction with the stepping action of the pedal section 27. When the pedal section 27 is released, the extension rod 24 is located at the upper position. In this manner, the first cymbal 11 supported by the first support section 21 of the extension rod 24 is separated toward the upper side X1 from the second cymbal 12 supported by the second support section 22 of the hollow shaft 25. When the pedal section 27 is stepped on, the extension rod 24 moves downward. As a result, the first cymbal 11 supported by the first support section 21 moves downward and approaches the second cymbal 12. When the pedal section 27 is fully stepped on, the first cymbal 11 comes into contact with the lower pad portion.

[0032] (1st cymbal unit) FIG. 5 is an exploded perspective view of the first cymbal unit 7. The first cymbal unit 7 includes a first cymbal 11 and a first holder 31 (holder) attached to the underside of the first cymbal 11. The first holder 31 is annular. The first holder 31 is fixed to the first cymbal 11 by six metal headed screws 32. Each of the headed screws 32 is conductive. The first cymbal unit 7 also includes a second holder 33 (second holder) attached to a portion of the circumferential direction on the outer circumferential side of the underside of the first cymbal 11. The second holder 33 is fixed to the first cymbal 11 by two headed screws 34 (second headed screws).

[0033] As shown in Figs. 2 and 4, the first cymbal 11 has a dome-shaped portion at its center that protrudes upward. In the first cymbal 11, the dome-shaped portion is called a bell 35. In the first cymbal 11, the outer peripheral edge is called an edge 36. In the first cymbal 11, the space between the bell 35 and the edge 36 is called a bow 37. The bow 37 is inclined downward X2 toward the outer peripheral side. The center of the bell 35, i.e., the center of the first cymbal 11, is provided with a central hole 11a through which the extension rod 24 passes when it is supported by the hi-hat stand 2.

[0034] 4, the first holder 31 holds a substrate 40, a first vibration sensor 41 that detects the vibration of the first cymbal 11, and a coil 42a of a distance sensor 42. A circuit section 42b of the distance sensor 42 and a circuit section 43a of a touch sensor 43 that detects when the player touches the first cymbal 11 are formed on the substrate 40. The second holder 33 holds a second vibration sensor 44 that detects the vibration of the first cymbal 11 on the outer periphery side of the first vibration sensor 41.

[0035] (First holder) The first holder 31 is attached to the lower surface of the first cymbal 11. The first holder 31 is made of resin or contains resin. The first holder 31 includes an annular plate portion 45 perpendicular to the central axis L of the first cymbal 11, an outer tapered plate portion 46 inclined upward from the outer peripheral edge of the annular plate portion 45 toward the outer peripheral side toward the upper side X1, an inner tapered plate portion 47 inclined upward from the inner peripheral edge of the annular plate portion 45 toward the upper side X1 toward the inner peripheral side, and an annular center plate portion 48 inclined from the upper edge of the inner tapered plate portion 47 toward the upper side X1 toward the inner peripheral side. The center plate portion 48 is provided with an annular protruding portion 49 protruding toward the upper side X1 at its center portion, and a circular tubular portion 50 extending from the opening edge of the center hole 11a of the protruding portion 49 toward the upper side X1.

[0036] 5, a recess 51 recessed toward the inner periphery is provided in a circumferential portion of the inner tapered plate portion 47. Furthermore, a notch 48a recessed toward the inner periphery corresponding to the recess 51 is provided in a circumferential portion of the center plate portion 48. The recess 51 includes a bottom plate portion 52 extending in a direction perpendicular to the central axis L, a pair of side plate portions 53 extending from both circumferential ends of the bottom plate portion 52 toward the upper side X1, and a connecting plate portion 54 extending in the circumferential direction and connecting the ends of the pair of side plate portions 53 on the inner periphery side. The center plate portion 48 is continuous from the upper end edges of each of the side plate portions 53 to the upper end edge of the connecting plate portion 54.

[0037] An opening 52a is provided in the circumferential center portion of the bottom plate portion 52. A board fixing portion 55 is provided on each of both sides in the circumferential direction of the opening 52a of the bottom plate portion 52. The board 40 is fixed to the pair of board fixing portions 55 from the upper side X1. It should be noted here that a connector 57 is attached to the bottom surface of the board 40. With the board 40 fixed to the pair of board fixing portions 55, the connector 57 can be viewed from the lower side X2 of the first holder 31 through the opening 52a.

[0038] The annular plate portion 45 has six bosses 58 arranged in an annular shape on the outer edge portion close to the outer tapered plate portion 46. The upper surface of each of the bosses 58 is provided with a screw hole that can be engaged with the headed screw 32. In this embodiment, the bosses 58 include six first bosses 58a provided at successive positions on the radially inner side of the outer tapered plate portion 46 and six second bosses 58b arranged in an annular shape between the first bosses 58a and the inner tapered plate portion 47.

[0039] In this embodiment, each of the headed screws 32 is inserted from the upper side X1 to the lower side X2 through the first cymbal 11 and screwed into each of the screw holes of the second boss 58b. This fixes the first holder 31 to the first cymbal 11. As shown in FIG. 4, when the first holder 31 is fixed to the first cymbal 11, the upper surface of the protruding portion 49 of the first holder 31 abuts against the opening edge of the center hole 11a of the first cymbal 11 from the lower side X2. Furthermore, the tube portion 50 of the first holder 31 fits into the center hole 11a of the first cymbal 11. As a result, the outer circumferential surface of the tube portion 50 contacts the inner wall surface of the center hole 11a of the first cymbal 11. The second boss 58b into which the headed screws 32 are screwed surrounds the bell 35 on the outer circumferential side of the bell 35. In this embodiment, the second boss 58b is provided at a position adjacent to the bell 35 of the bow 37. The six first bosses 58a, into which the headed screws 32 are not screwed, surround the bell 35 in the circumferential direction more than the second bosses 58b.

[0040] In the electronic musical instrument 4 of this embodiment, cymbals of a variety of sizes can be used as the first cymbal 11. For example, when using a large first cymbal 11 having a larger outer diameter than the first cymbal 11 of this embodiment and a bell 35 having a larger outer diameter than the bell 35 of this embodiment, the boss 58 into which the headed screw 32 is screwed is specified to be the first boss 58a. In this case, when the first holder 31 is fixed to the first cymbal 11, the first boss 58a into which the headed screw 32 is screwed surrounds the bell 35 on the outer periphery side of the bell 35. The six second bosses 58b into which the headed screws 32 are not screwed are positioned so as to overlap the bell 35 when viewed from the up-down direction X.

[0041] When the first holder 31 is fixed to the first cymbal 11, the annular plate portion 45 is positioned on the lower side X2 from the edge 36 of the first cymbal 11. In other words, the annular plate portion 45 is positioned away from the first cymbal 11 toward the lower side X2.

[0042] (Second holder) The second holder 33 includes a circular sensor support portion 61, a frame portion 62 extending upward from the outer periphery of the sensor support portion 61 to the upper side X1, and a wiring pull-out portion 63 extending radially outward by cutting out a portion of the frame portion 62 in the circumferential direction. The sensor support portion 61 has bosses 64 at two opposing positions in the circumferential direction. The upper surface of each of the bosses 64 has a screw hole with which the headed screw 34 can be engaged. The second holder 33 is fixed to the first cymbal 11 by the headed screws 34 that are inserted through the first cymbal 11 and screwed into each screw hole of the bosses 64.

[0043] (Sensor) FIG. 6 is an explanatory diagram showing the mounting state of the first vibration sensor 41. FIG. 6 is a partially enlarged cross-sectional view of the first vibration sensor 41. The first vibration sensor 41 includes a piezoelectric element. The first vibration sensor 41 converts the vibration of the first cymbal 11 into an electric signal and outputs it. As shown in FIG. 4 and FIG. 5, the first vibration sensor 41 is disposed on the center plate portion 48 of the first holder 31. Therefore, the first vibration sensor 41 overlaps with the bell 35 when viewed from the up-down direction X. As shown in FIG. 6, the first vibration sensor 41 is disposed on the center plate portion 48 via a sheet-like first elastic member 65. The first elastic member 65 is, for example, a sponge. Furthermore, the first vibration sensor 41 contacts the lower surface of the bell 35 via a sheet-like second elastic member 66. Therefore, the first vibration sensor 41 detects the vibration of the first cymbal 11 (mainly the vibration of the bell 35) via the second elastic member 66. The second elastic member 66 is an insulating member and is harder (e.g., has a higher Shore hardness) than the first elastic member 65. In this embodiment, the second elastic member 66 is rubber or contains rubber. The first vibration sensor 41 is connected to the substrate 40 via a lead wire (not shown).

[0044] The touch sensor 43 is of a capacitance type. As shown in FIG. 5, the touch sensor 43 includes a circuit section 43a provided on the substrate 40 and a touch electrode. In this embodiment, the touch electrode is the first cymbal 11. Therefore, when a player having capacitance touches the first cymbal 11, the ground-to-ground capacitance of the first cymbal 11 changes. As a result, an electric signal corresponding to the change in ground-to-ground capacitance is output from the touch sensor 43. In other words, when a player executes a mute operation by touching the first cymbal 11, a signal corresponding to the mute operation is output from the touch sensor 43.

[0045] In order to make the first cymbal 11 a touch electrode, the first cymbal unit 7 includes a lead wire 68 that electrically connects the substrate 40 to the first cymbal 11, and a conductive terminal 69. The terminal 69 includes a connection portion 69a to which the lead wire 68 is connected, and a through hole 69b into which the shaft of the headed screw 32 can be inserted. When the first holder 31 is fixed to the first cymbal 11, the terminal 69 is sandwiched between the upper surface of the first boss 58a that is the closest to the recess 51 among the six first bosses 58a, and the first cymbal 11, and the headed screw 32 is inserted from the through hole 69b. As a result, the terminal 69 and the first cymbal 11 come into contact with each other and are electrically connected, so that the first cymbal 11 functions as a touch electrode of the touch sensor 43. Furthermore, since the headed screw 32 for fixing the first holder 31 to the first cymbal 11 is conductive, the circuit portion 43a of the touch sensor 43 and the first cymbal 11 are electrically connected via the terminal 69 and the headed screw 32. This makes it possible to ensure the connection between the circuit portion 43a of the touch sensor 43 and the first cymbal 11.

[0046] The distance sensor 42 is a proximity sensor that includes an oscillator circuit having a coil 42a and outputs a signal oscillated by the oscillator circuit. The coil 42a is fixed to the annular plate portion 45 of the first holder 31 with its opening oriented in the vertical direction X. The coil 42a surrounds the inner tapered plate portion 47. The coil 42a is positioned on the lower side X2 of the edge 36 of the first cymbal 11. In other words, the first holder 31 supports the coil 42a at a position spaced away from the first cymbal 11 toward the lower side X2. The circuit portion 42b of the distance sensor 42 is provided on the substrate 40.

[0047] It should be noted here that the second cymbal 12 is made of or contains a metal exhibiting electrical conductivity. Therefore, the frequency and amplitude of the signal oscillated by the oscillator circuit varies in response to the distance between the first cymbal 11 and the second cymbal 12. Therefore, a signal corresponding to the distance between the first cymbal 11 and the second cymbal 12 can be output from the distance sensor 42.

[0048] The second vibration sensor 44 includes a piezoelectric element. In this embodiment, the first vibration sensor 41 and the second vibration sensor 44 are of the same type. The second vibration sensor 44 converts the vibration of the first cymbal 11 into an electric signal and outputs it. As shown in FIG. 4, the second vibration sensor 44 is fixed to the sensor support portion 61 of the second holder 33. In a state in which the second holder 33 is fixed to the first cymbal 11, the second vibration sensor 44 overlaps a part of the bow 37 that is closer to the edge 36 than the bell 35.

[0049] Here, the second vibration sensor 44 faces the bow 37 with a gap therebetween. A wire 70 extending radially inward from the second vibration sensor 44 is drawn out via the wire draw-out portion 63 of the second holder 33. The wire 70 is drawn in a straight line along the underside of the first cymbal 11 and connected to the substrate 40. The wire 70 is adhered to the underside of the first cymbal 11. As with the first vibration sensor 41, an elastic member such as rubber may be inserted between the second vibration sensor 44 and the first cymbal 11.

[0050] It should be noted here that the first vibration sensor 41, the touch sensor 43, the distance sensor 42, and the second vibration sensor 44 are electrically connected to the connector 57 via the substrate 40.

[0051] (2nd cymbal unit) 7 is an exploded perspective view of the second cymbal unit 8. As shown in FIGS. 3 and 4, the second cymbal unit 8 includes the second cymbal 12, a shock absorbing member 75, and a cable guide 76.

[0052] The second cymbal 12 includes, at its center, a dome-shaped portion 81 that protrudes downward. Furthermore, the second cymbal 12 includes, on the outer circumferential side of the central portion, an annular tapered portion 82 that extends upwards X1 toward the outer circumferential side. Furthermore, the second cymbal 12 includes a wiring hole 83 that is opened so as to penetrate in the up-down direction X in a portion of the circumferential direction of the dome-shaped portion 81 that is closer to the tapered portion 82 than the center hole 12a.

[0053] As shown in FIG. 7, the shock absorbing member 75 is attached to the outer periphery of the second cymbal 12. As a result, the outer periphery of the upper surface of the second cymbal 12 is covered with the shock absorbing member 75. In this embodiment, the shock absorbing member 75 is made of rubber or contains rubber. The shock absorbing member 75 is annular and has a rectangular cross section. The shock absorbing member 75 has a groove extending in the circumferential direction at the center of the up-down direction X of the surface facing inward in the radial direction. The shock absorbing member 75 is attached to the second cymbal 12 by inserting the outer periphery of the second cymbal 12 into this groove. It should be noted that the shock absorbing member 75 may be a gel-like member. A ring-shaped rubber or gel-like material may be attached to the outer periphery of the upper surface of the second cymbal 12.

[0054] As shown in FIG. 4, the cable guide 76 is inserted through the wiring hole 83 and fixed to the wiring hole 83. As shown in FIG. 7, the cable guide 76 includes a curved plate portion 85 curved in a C-shape when viewed from the up-down direction X, a lower curved wall portion 86 extending from the inner peripheral edge of the curved plate portion 85 to the lower side X2, an upper curved wall portion 87 extending from the outer peripheral edge of the curved plate portion 85 to the upper side X1, and a flange portion 88 expanding from the upper end edge of the upper curved wall portion 87 toward the outer peripheral side. The cable guide 76 is inserted into the wiring hole 83 from the upper side X1 with the open parts of the curved plate portion 85, the lower curved wall portion 86, and the upper curved wall portion 87 oriented radially outward. When the cable guide 76 is inserted into the wiring hole 83 and fixed to the second cymbal 12, the flange portion 88 abuts against the opening edge of the wiring hole 83 on the upper surface of the second cymbal 12. The upper curved wall portion 87 protrudes from the second cymbal 12 toward the lower side X2 through the wiring hole 83. The lower curved wall portion 86 is disposed at a position spaced away from the second cymbal 12 toward the lower side X2.

[0055] (Module) FIG. 8 is a schematic block diagram showing a control system of the electronic hi-hat cymbal 1. As shown in FIG. 8, the module 6 includes an attack signal generating unit 101 for generating an attack signal indicating a time point of a strike based on an output from the first vibration sensor 41, a dynamic signal generating unit 102 for generating a dynamic signal indicating a strength of a strike based on an output from the second vibration sensor 44, and a strike position signal generating unit 103 for generating a strike position signal indicating a strike position on the first cymbal 11 based on the output from the first vibration sensor 41 and the output from the second vibration sensor 44. The module 6 also includes a mute signal generating unit 104 for generating a mute signal indicating a mute based on an output from the touch sensor 43, and a separation distance signal generating unit 105 for generating a separation distance signal indicating a separation distance based on an output from the distance sensor 42. Furthermore, the module 6 includes an output unit 107 for outputting the attack signal, the dynamic signal, the strike position signal, the mute signal, and the separation distance signal to the outside. The signals from the output unit 107 of the module 6 are input to a sound source device.

[0056] (Electronic hi-hat and cymbal) When the electronic musical instrument 4 is supported by the hi-hat stand 2, the second cymbal 12 having the shock absorbing member 75 is first supported on the second support part 22. Next, the cable 5 is routed from the lower side X2 of the second cymbal 12 to the upper side X1 through the wiring hole 83 of the second cymbal 12. As shown in Fig. 4, the cable 5 includes, at its upper end, a cable side connector 90 that can be attached to and detached from the connector 57.

[0057] Next, the cable guide 76 is attached to the back surface of the cable side connector 90 of the cable 5. In this case, the cable 5 is inserted into the curved plate portion 85, the lower curved wall portion 86, the upper curved wall portion 87, and the flange portion 88 from the open portions of the curved plate portion 85, the lower curved wall portion 86, the upper curved wall portion 87, and the flange portion 88 of the cable guide 76.

[0058] The cable guide 76 is fixed to the second cymbal 12 with the flange 88 in contact with the upper surface of the second cymbal 12. As shown in FIG. 3, when the cable guide 76 is fixed to the second cymbal 12, the upper curved wall 87 passes through the wiring hole 83 and protrudes from the second cymbal 12 to the lower side X2. The lower curved wall 86 is disposed at a position away from the second cymbal 12 toward the lower side X2. Thus, the lower curved wall 86 has a pair of opposing portions 86a facing the cable 5 from both sides in the circumferential direction at a position away from the cymbal 12 to the lower side X2. Note that the inner diameter of the lower curved wall 86 is slightly larger than the outer diameter of the cable 5, and the cable guide 76 allows the cable 5 to move in the up-down direction X. The upper curved wall 87 is sized to receive a cable connector 90 from the upper side X1.

[0059] Next, as shown in FIG. 4, the cable side connector 90 is attached to the connector 57 through the opening 52a of the first holder 31. As a result, the first vibration sensor 41, the touch sensor 43, the distance sensor 42, and the second vibration sensor 44 provided for the first cymbal unit 7 are electrically connected to the cable 5. After that, the first cymbal 11 is supported on the first support part 21. When the first cymbal 11 is supported by the first support part 21 of the hi-hat stand 2, the extension rod 24 is inserted in the vertical direction X through the tube part 50 of the first holder 31 fitted in the center hole 11a of the first cymbal 11. It should be noted that the order of connecting the cable 5 to the connector 57 and supporting the first cymbal 11 on the first support part 21 may be reversed.

[0060] A first cymbal 11 is supported by a first support portion 21 of a hi-hat stand 2, and a second cymbal 12 is supported by a second support portion 22, forming an electronic hi-hat cymbal 1.

[0061] Next, the first cymbal 11 and the second cymbal 12 are rotated relative to each other around the axis, so that the wiring hole 83 of the first holder 31 and the wiring hole 83 of the second cymbal 12 overlap each other when viewed from the up-down direction X. In this state, the cable 5 is pulled downward, and the cable 5 extends in a straight line from the first holder 31 toward the second cymbal 12. Thereafter, as shown in FIG. 1, the cable 5 is connected to the module 6. The cable 5 inserted through the second cymbal 12 to the underside X2 is routed while in contact with the floor surface or the like, and then connected to the module 6.

[0062] Here, when the first cymbal 11 supported by the hi-hat stand 2 tries to rotate in the circumferential direction, the pair of opposing parts 86a of the cable guide 76 interfere with the cable 5 from the circumferential direction, restricting the relative rotation of the first cymbal 11 and the second cymbal 12. Furthermore, the cable 5 inserted through the second cymbal 12 and extending toward the lower side X2 is routed while in contact with the floor surface, etc., so that the movement of the cable 5 itself is also restricted by the floor surface. As a result, the first cymbal 11 and the second cymbal 12 are prevented from rotating excessively. By preventing or suppressing the excessive rotation of the first cymbal 11 due to striking, it is possible to prevent or suppress excessive displacement in the circumferential direction of the position of the vibration sensor attached to the first cymbal 11. This makes it possible to suppress excessive changes in the level of the signal from the vibration sensor caused by excessive changes in the distance between the striking position of the performer and the first vibration sensor 41 and the second vibration sensor 44 caused by the rotation of the first cymbal 11.

[0063] Furthermore, in the electronic hi-hat cymbal 1, the first cymbal 11 supported by the first support portion 21 is raised and lowered by operating the pedal portion 27 of the lifting mechanism 23. Note that the distance sensor 42 is supported at a position away from the first cymbal 11 toward the lower side X2 by the first holder 31 fixed to the back surface of the first cymbal 11. Therefore, the coil 42a moves in the vertical direction X together with the first cymbal 11, below the first cymbal 11 at the lower side X2.

[0064] (Action and effect) The electronic musical instrument 4 of this embodiment includes a first cymbal 11 made of metal or containing metal. Therefore, when striking the first cymbal 11, the performer can obtain the same playing feeling as when striking an actual cymbal. The electronic musical instrument 4 also includes a capacitance-type touch sensor 43 (e.g., a capacitive touch sensor), and the first cymbal 11 is used as a touch electrode of the touch sensor 43. Therefore, when a performer having capacitance touches the first cymbal 11, the ground-to-ground capacitance of the first cymbal 11 changes, and a signal corresponding to this change in ground-to-ground capacitance is output from the touch sensor 43. Therefore, when the performer touches the first cymbal 11 in the same way as when muting an actual cymbal, a signal indicating muting can be output from the touch sensor 43. This eliminates the need for the performer to check the area that the performer is required to touch when muting the first cymbal 11. Therefore, it is possible to prevent or suppress the loss of playing feeling of the performer playing the electronic musical instrument 4 when muting the first cymbal 11.

[0065] The first cymbal unit 7 includes a first vibration sensor 41 that detects the vibration of the first cymbal 11, and a second vibration sensor 44 that detects the vibration of the first cymbal 11 on the outer circumferential side of the first vibration sensor 41. The first vibration sensor 41 overlaps with the bell 35 of the first cymbal 11 when viewed from the up-down direction X, and the second vibration sensor 44 overlaps with a part of the bow 37 of the first cymbal 11 that is closer to the edge 36 than the bell 35. In this way, the electronic musical instrument 4 includes two vibration sensors at different positions in the radial direction of the first cymbal 11. Therefore, it is easy to obtain the striking position on the first cymbal 11 based on the signals output from each of these two vibration sensors.

[0066] Furthermore, the first cymbal unit 7 includes a substrate 40 on which a circuit section 43a of a touch sensor 43b is formed, a resin first holder 31 that supports the substrate 40 and the first vibration sensor 41, and headed screws 32 for fixing the first holder 31 to the underside of the first cymbal 11. The first cymbal 11 has a central hole 11a. The first holder 31 includes a tube section 50 that is inserted into the central hole 11a, and first bosses 58a that are arranged in an annular shape on the outer periphery of the tube section 50. The outer periphery of the tube section 50 contacts the inner wall surface of the central hole 11a of the first cymbal 11. The first holder 31 is fixed to the first cymbal 11 by threading each of the headed screws 32 through the first cymbal 11 from the upper side X1 to the lower side X2 and screwing them into the respective screw holes of the second bosses 58b. When the first holder 31 is fixed to the first cymbal 11, the second boss 58b surrounds the bell 35 on the outer periphery. As a result, the first holder 31 is fixed to the first cymbal 11 in a state of contact with the opening edge of the center hole 11a of the first cymbal 11 and the outer periphery of the bell 35. Therefore, when the first cymbal 11 is struck, the first holder 31 functions as a damper for quickly attenuating the vibration of the bell 35. Since the first cymbal 11 is made of metal or contains metal, the vibration generated by the strike is likely to generate swells, and the amplitude repeatedly increases and decreases. Therefore, there is a problem that the strike time, which is the time of the maximum amplitude, tends to be erroneously detected. Regarding such a problem, the first holder 31 functions as a damper for quickly attenuating the vibration of the bell 35. Therefore, in this embodiment, it is easy to obtain the strike time based on the signal from the first vibration sensor 41.

[0067] In this embodiment, the first holder 31 includes a first boss 58a and a second boss 58b arranged in a ring shape at different positions in the radial direction. When the first holder 31 is fixed to the first cymbal 11, the boss 58 into which the headed screw 32 is screwed can be selected between the first boss 58a and the second boss 58b. Therefore, when there are two types of first cymbals 11 having different radial sizes as the first cymbals 11, one first holder 31 can be shared by the two types of first cymbals 11. Even when one first holder 31 is shared between two different types of first cymbals 11 having different radial sizes, the boss 58 into which the headed screw 32 is screwed can be positioned on the outer periphery of the bell 35.

[0068] In the electronic hi-hat cymbal 1, the distance between the first cymbal 11 and the second cymbal 12 is changed by operating the pedal. Therefore, in order to reproduce the beating sound, it is necessary to have a distance sensor 42 that outputs a signal to obtain the distance between the first cymbal 11 and the second cymbal 12. On the contrary, in this embodiment, the first cymbal unit 7 includes a distance sensor 42 that is supported by the first holder 31 and outputs a signal corresponding to the distance between the first cymbal 11 and the second cymbal 12 in the up-down direction X. The distance sensor 42 is an oscillation type proximity sensor that includes an oscillation circuit having a coil 42a whose opening faces the up-down direction X and outputs a signal oscillated by the oscillation circuit. It should be noted here that the second cymbal 12 is made of a metal exhibiting electrical conductivity or contains a metal exhibiting electrical conductivity. Therefore, the frequency and amplitude of the signal oscillated by the oscillation circuit vary corresponding to the distance between the first cymbal 11 and the second cymbal 12. Therefore, a signal corresponding to the distance between the first cymbal 11 and the second cymbal 12 can be output from the distance sensor 42. Furthermore, the coil 42a is positioned on the lower side X2 of the edge 36 of the first cymbal 11. In other words, the first holder 31 supports the coil 42a at a position away from the first cymbal 11 toward the lower side X2. This makes it possible to detect the distance between the first cymbal 11 and the second cymbal 12 with high accuracy.

[0069] Furthermore, the second cymbal 12 has a smaller outer diameter than the first cymbal 11, and the outer periphery of the upper surface of the second cymbal 12 is covered with a shock absorbing member 75. Therefore, when the first cymbal 11, which is made of metal or contains metal, and the second cymbal 12, which is made of metal or contains metal, come into contact with each other, it is possible to prevent or suppress damage to the first cymbal 11. Since the outer periphery of the upper surface of the second cymbal 12 is covered with the shock absorbing member 75, the rattling sound generated when the first cymbal 11 and the second cymbal 12 are played with an opening that allows them to come into contact with each other is not transmitted to the first vibration sensor and the second vibration sensor.

[0070] Furthermore, the electronic hi-hat cymbal 1 of this embodiment includes a module 6 connected to the electronic musical instrument 4 via a cable 5. The module 6 generates an attack signal indicative of the time of striking based on the output from the first vibration sensor 41. The module 6 also generates a dynamic signal indicative of the strength of the striking based on the output from the second vibration sensor 44.

[0071] Since the first cymbal 11 is made of metal or contains metal, the vibrations generated by striking the cymbal 11 tend to generate swells, and the amplitude repeatedly increases and decreases. Therefore, there is a problem that an attack signal that has the maximum amplitude as the striking time tends to be erroneously detected. Regarding such a problem, the signal from the first vibration sensor 41 arranged at a position overlapping the bell 35 of the first cymbal 11 has fewer low-frequency band components than the signal from the second vibration sensor 44 arranged at a position overlapping the bow 37, and the amplitude tends to attenuate over time. The amplitude of the vibration of the bell 35 is easily attenuated by the first holder 31 fixed to the first cymbal 11. Therefore, by acquiring the attack signal based on the signal from the first vibration sensor 41, it is possible to prevent or suppress the attack signal generation unit 101 from erroneously detecting the attack signal.

[0072] Furthermore, since the signal from the second vibration sensor 44 arranged at a position overlapping with the bow 37 has more low frequency band components than the signal from the first vibration sensor 41 arranged at a position overlapping with the bell 35, it is easier to obtain the amplitude of vibration corresponding to the strength of the strike. Therefore, the dynamic signal generating unit 102 can easily generate a dynamic signal indicating the strength of the strike based on the signal from the second vibration sensor 44.

[0073] Furthermore, the module 6 includes an output unit 107 for outputting an attack signal, a dynamic signal, a tapping position signal, a mute signal, and a separation distance signal that are generated based on the output from each of the sensors of the electronic musical instrument 4. Therefore, by inputting the signals from the output unit 107 of the module 6 to a sound source device, a tapping sound corresponding to a tap on the electronic musical instrument 4 can be generated from the sound source device.

[0074] (Other embodiments) 9 is a perspective view of the second cymbal unit 8 as viewed from the upper side X1 when the second cymbal 12 is made of or contains resin. The second cymbal 12A of this embodiment is made of or contains a non-conductive material (e.g., an insulating material) such as resin. Since the second cymbal 12A has a configuration corresponding to that of the second cymbal 12, the same reference numerals are used for corresponding parts and their description is omitted.

[0075] When the second cymbal 12A is made of or contains resin, the second cymbal unit 8 includes a conductive metal member 95 fixed to the second cymbal 12A, as shown in FIG. 9. In the example shown in FIG. 9, the metal member 95 is annular. The metal member 95 is fixed to the boundary between the dome-shaped portion 81 and the tapered portion 82 of the second cymbal 12A via a conductive headed screw 96. The metal member 95 is disposed coaxially with the coil 42a of the distance sensor 42 provided in the first cymbal unit 7. Furthermore, when viewed from the up-down direction X, the metal member 95 overlaps with the coil 42a of the distance sensor 42.

[0076] In this way, a signal corresponding to the distance between the first cymbal 11 and the second cymbal 12A can also be output from the distance sensor 42. In this embodiment, the coil 42a constituting the oscillator circuit of the distance sensor 42 is positioned on the lower side X2 from the edge 36 of the first cymbal 11. In other words, the first holder 31 supports the coil 42a at a position away from the first cymbal 11 toward the lower side X2. This makes it possible to detect the distance between the first cymbal 11 and the second cymbal 12A with high accuracy. When the second cymbal 12A is made of resin or contains resin, the shock absorbing member 75 may be omitted.

[0077] The first cymbal unit 7 may include a plurality of first vibration sensors 41 arranged in a circumferential direction at positions overlapping with the bell 35. The first cymbal unit 7 may also include a plurality of second vibration sensors 44 arranged in a circumferential direction at positions overlapping with the bow 37. Furthermore, the first cymbal unit 7 may also include a plurality of second vibration sensors 44 arranged in a radial direction at positions overlapping with the bow 37.

[0078] Furthermore, out of the first boss 58a and the second boss 58b, the first holder 31 may include only one of the bosses 58 that corresponds to the size of the first cymbal 11 to be used. Furthermore, only the first cymbal unit 7 may be supported by a cymbal stand and used as the electronic musical instrument 4. In this case, the distance sensor 42 of the first cymbal unit 7 may be omitted.

[0079] Second embodiment FIG. 10 is an explanatory diagram of an electronic hi-hat cymbal according to a second embodiment. FIG. 11 is a cross-sectional view of the electronic cymbal of FIG. 10. FIG. 12 is an exploded perspective view of the first cymbal unit of FIG. 10. The electronic hi-hat cymbal 1A of this embodiment includes an electronic musical instrument 4 supported by a commercially available hi-hat stand 2, and a module 6 (control unit) electrically connected to the electronic musical instrument 4 via a cable 5. The electronic musical instrument 4, the cable 5, and the module 6 constitute a cymbal set 3. In this embodiment, the electronic musical instrument 4 includes a first cymbal unit 7 and a second cymbal unit 8.

[0080] The electronic hi-hat cymbal 1A of this embodiment is the same as the electronic hi-hat cymbal 1, except for the first cymbal unit 7. Therefore, only the first cymbal unit 7 will be described, and other descriptions will be omitted. The electronic hi-hat cymbal 1A of this embodiment has a configuration corresponding to the above-mentioned electronic hi-hat cymbal 1. Therefore, the same reference numerals will be used for corresponding structures, and detailed descriptions thereof will be omitted.

[0081] (1st cymbal unit) As shown in FIG. 10, the first cymbal unit 7 includes a first cymbal 11 made of metal or containing metal, a first holder 31 (holder) attached to the underside of the first cymbal 11, and a second holder 33 (second holder). The first holder 31 is fixed to the underside of the first cymbal 11 by a nut 60. The second holder 33 is fixed to the underside of the first cymbal 11 by two headed screws (second headed screws). Furthermore, as shown in FIG. 12, the first cymbal unit 7 includes a substrate 40, a first vibration sensor 41, a touch sensor 43, a distance sensor 42, and a second vibration sensor 44.

[0082] (First cymbal) As shown in Fig. 10, the center of the first cymbal 11 is located on the upper side X1 compared to the outer periphery. The first cymbal 11 may have a number of small holes 15 drilled in the vertical direction across the entire surface to suppress the volume of the striking sound when the first cymbal 11 is struck. As shown in Fig. 11, the first cymbal 11 includes a bell 35, a bow 37, and an edge 36, in this order from the center toward the outer periphery. A central hole 11a is provided at the center of the bell 35, i.e., the center of the first cymbal 11, through which the extension rod 24 passes when supported by the hi-hat stand 2.

[0083] As shown in Fig. 12, the first holder 31 is annular. As shown in Fig. 11, the first holder 31 holds a substrate 40, a first vibration sensor 41, and a coil 42a of a distance sensor 42. A circuit section 42b of the distance sensor 42 and a circuit section 43a of a touch sensor 43 are formed on the substrate 40. The second holder 33 holds a second vibration sensor 44 that detects vibration of the first cymbal 11 on the outer periphery side of the first vibration sensor 41.

[0084] (First holder) The first holder 31 is made of resin or contains resin. The first holder 31 includes an annular plate portion 45 perpendicular to the central axis L of the first cymbal 11, an outer tapered plate portion 46 inclined upward from the outer peripheral edge of the annular plate portion 45 toward the outer peripheral side toward the upper side X1, an inner tapered plate portion 47 inclined upward from the inner peripheral edge of the annular plate portion 45 toward the upper side X1 toward the inner peripheral side, and an annular center plate portion 48 inclined from the upper edge of the inner tapered plate portion 47 toward the upper side X1 toward the inner peripheral side. The center plate portion 48 is provided with an annular protruding portion 49 protruding toward the upper side X1 at its center portion, and a tubular portion 50 extending from the opening edge of the center hole 11a of the protruding portion 49 toward the upper side X1.

[0085] The cylindrical portion 50 has a male thread 50a on its outer circumferential surface. The male thread 50a can be engaged with a nut 60. An annular plate portion 49a for adjusting the upper surface of the protruding portion 49 extends from the lower end portion of the cylindrical portion 50 toward the outer circumferential side.

[0086] 12, a recess 51 recessed toward the inner periphery is provided in a circumferential portion of the inner tapered plate portion 47. Furthermore, a notch 48a recessed toward the inner periphery corresponding to the recess 51 is provided in a circumferential portion of the center plate portion 48. The recess 51 includes a bottom plate portion 52 extending in a direction perpendicular to the central axis L, a pair of side plate portions 53 extending from both circumferential ends of the bottom plate portion 52 toward the upper side X1, and a connecting plate portion 54 extending in the circumferential direction and connecting the ends of the pair of side plate portions 53 on the inner periphery side. The center plate portion 48 is continuous from the upper end edges of each of the side plate portions 53 to the upper end edge of the connecting plate portion 54.

[0087] An opening 52a is provided in the circumferential center portion of the bottom plate portion 52. A board fixing portion 55 is provided on each of both sides in the circumferential direction of the opening 52a of the bottom plate portion 52. The board 40 is fixed to the pair of board fixing portions 55 from the upper side X1. It should be noted here that a connector 57 is attached to the lower surface of the board 40. With the board 40 fixed to the pair of board fixing portions 55, the connector 57 can be viewed from the lower side X2 of the first holder 31 through the opening 52a.

[0088] 11 and 12, first vibration sensor 41 is disposed on central plate portion 48 of first holder 31. First vibration sensor 41 overlaps with bell 35 when viewed from the up-down direction X. First vibration sensor 41 is disposed on central plate portion 48 via sheet-like first elastic member 65. Furthermore, first vibration sensor 41 contacts the underside of bell 35 via sheet-like second elastic member 66 (see FIG. 6). First vibration sensor 41 is connected to substrate 40 via lead wires (not shown).

[0089] The touch sensor 43 includes a circuit section 43a provided on the substrate 40 and a touch electrode. The touch electrode is the first cymbal 11. In order to make the first cymbal 11 a touch electrode, the first cymbal unit 7 includes a lead wire 68 that electrically connects the substrate 40 to the first cymbal 11, and a conductive terminal 69 (conductive member). The terminal 69 includes a connection unit 71 to which the lead wire 68 is connected, and an annular portion 72. It should be noted here that the entire annular plate portion 49a that adjusts the upper surface of the protrusion 49 is the mounting portion on which the annular portion 72 is disposed. As shown in FIG. 11, the annular portion 72 is disposed on the annular plate portion 49a with the tube portion 50 of the first holder 31 inserted into its center hole.

[0090] The coil 42a of the distance sensor 42 is fixed to the annular plate portion 45 of the first holder 31 with the opening oriented in the vertical direction X. The coil 42a surrounds the inner tapered plate portion 47. The circuit portion 42b of the distance sensor 42 is provided on the substrate 40.

[0091] When the first holder 31 is fixed to the first cymbal 11, the annular portion 72 of the terminal 69 is placed on the annular plate portion 49a, and the tube portion 50 is inserted into the central hole 11a of the first cymbal 11. This causes the upper end of the tube portion 50 to protrude from the first cymbal 11 toward the upper side X1. Therefore, the male thread 50a provided on the tube portion 50 is exposed to the upper side X1 of the first cymbal 11. The outer peripheral surface of the tube portion 50 contacts the inner wall of the central hole 11a of the first cymbal 11. The annular portion 72 of the terminal 69 is positioned between the protruding portion 49 and the first cymbal 11 on the outer peripheral side of the tube portion 50.

[0092] Next, the nut 60 is screwed onto the male thread 50a of the cylindrical portion 50 from the upper side X1 of the first cymbal 11. This fixes the first holder 31 to the first cymbal 11. Here, when the first holder 31 is fixed to the first cymbal 11, the annular portion 72 of the terminal 69 is sandwiched between the annular plate portion 49a of the protruding portion 49 and the opening edge of the center hole 11a on the underside of the first cymbal 11. As a result, the circuit portion 43a is electrically connected to the first cymbal 11 via the lead wire 68 and the terminal 69.

[0093] Furthermore, when the first holder 31 is fixed to the first cymbal 11, the annular plate portion 45 of the first holder 31 is positioned on the lower side X2 of the edge 36 of the first cymbal 11. Therefore, the coil 42a of the distance sensor 42 is positioned on the lower side X2 of the edge 36 of the first cymbal 11. In other words, the first holder 31 supports the coil 42a at a position away from the first cymbal 11 toward the lower side X2.

[0094] Furthermore, when the first holder 31 is fixed to the first cymbal 11, the upper end of the outer tapered plate portion 46 does not come into contact with the first cymbal 11. In other words, on the further outer circumferential side than the annular plate portion 45, the first holder 31 does not have a portion that comes into contact with the first cymbal 11.

[0095] (Second holder) As shown in Fig. 11 and Fig. 12, the second holder 33 holds the second vibration sensor 44. As shown in Fig. 12, the second holder 33 includes a circular sensor support part 61, a frame part 62 extending upward from the outer periphery of the sensor support part 61 to the upper side X1, and a wiring lead-out part 63 extending radially outward by cutting out a part of the circumferential direction of the frame part 62. The second vibration sensor 44 is supported by the sensor support part 61. Furthermore, the second holder has a first screw hole 67a on one side of the second vibration sensor 44 in the frame part 62, and a second screw hole 67b on the other side.

[0096] The second holder 33 is fixed to the underside of the first cymbal 11 by two headed screws 34 that are inserted through the first cymbal 11 and screwed into the first screw hole 67a and the second screw hole 67b. When the second holder 33 is fixed to the first cymbal 11, the two headed screws 34 that are screwed into the screw holes 67a and 67b are aligned in the radial direction of the first cymbal 11 as shown in Figures 10 and 11.

[0097] Furthermore, with the second holder 33 fixed to the first cymbal 11, the second vibration sensor 44 overlaps a part of the bow 37 that is closer to the edge 36 than the bell 35. Furthermore, the second vibration sensor 44 faces the bow 37 with a gap therebetween. The second vibration sensor 44 is connected to the board 40 by a wire 70 that is drawn out through the wire drawing section 63.

[0098] (Action and effect) This embodiment includes a nut 60 for fixing the first holder 31 to the first cymbal 11, a lead wire 68 for electrically connecting the circuit section 43a of the touch sensor 43 to the first cymbal 11, and a terminal 69 connected to the lead wire 68. The first holder 31 includes an annular plate section 49a that spreads from the lower end of the tube section 50 to the outer periphery, and a male screw 50a provided on the outer periphery of the tube section 50. The annular plate section 49a is a mounting section on which a conductive member is disposed. On the outer periphery side further than the annular plate section 49a, the first holder 31 does not have a portion that contacts the first cymbal 11. Therefore, the first holder 31 is fixed to the first cymbal 11 at a position close to the center of the first cymbal 11. As a result, the sound produced when first cymbal 11 is struck is closer to the sound produced when an actual cymbal is struck, compared to a case in which boss 58 for fixing first holder 31 to first cymbal 11 surrounds bell 35 on the outer periphery of bell 35. Therefore, the playing feel when the player strikes first cymbal 11 can be made closer to the playing feel when a conventional cymbal is struck.

[0099] On the other hand, the first holder 31 is fixed to the first cymbal 11 by a nut 60 screwed onto the male thread 50a of the tube portion 50 protruding from the first cymbal 11 toward the upper side X1. It should be noted that the contact area of ​​the nut 60 with the surface of the first cymbal 11 is relatively large. Therefore, the first holder 31 fixed to the first cymbal 11 by the nut 60 functions as a damper for quickly attenuating the vibration of the bell 35. Since the first cymbal 11 is made of metal or contains metal, the vibration generated by hitting it tends to generate swells, and the amplitude repeatedly increases and decreases. Therefore, there is a problem that the time of hitting, which is the time of the maximum amplitude, tends to be erroneously detected. Regarding such a problem, when the first holder 31 functions as a damper for quickly attenuating the vibration of the bell 35, it becomes easy to obtain the time of hitting based on the signal from the first vibration sensor 41.

[0100] Furthermore, by screwing the nut 60 into the tube portion 50 of the first holder 31, the terminal 69 is sandwiched between the first cymbal 11 and the annular plate portion 49a. This connects the circuit portion 42b of the touch sensor 43a to the first cymbal 11 via the lead wire 68 and the terminal 69. This makes it easy to use the first cymbal 11 as a touch electrode of the touch sensor 43.

[0101] Furthermore, the second holder 33 has a first screw hole 67a on one side of the second vibration sensor 44 in the frame portion 62, and a second screw hole 67b on the other side. The second holder 33 is fixed to the lower surface of the first cymbal 11 by two headed screws 34 that are inserted through the first cymbal 11 and screwed into the first screw hole 67a and the second screw hole 67b. When the second holder 33 is fixed to the first cymbal 11, the two headed screws 34 that are screwed into the screw holes 67a and 67b are arranged in the radial direction of the first cymbal 11. Therefore, it becomes easier for the second vibration sensor 44 to detect the vibration of the first cymbal 11. In other words, when the first cymbal 11 is struck, the vibration is propagated in the circumferential direction as the undulation of the bow 37. Therefore, when the two headed screws 34 are arranged in the circumferential direction of the first cymbal 11 when the second holder 33 is fixed to the first cymbal 11, the undulation of the bow 37 tends to be hindered by the two headed screws 34 and the second holder 33, and the amplitude of the vibration caused by the strike tends to be reduced. In contrast, when the two headed screws 34 for fixing the second holder 33 are arranged in the radial direction of the first cymbal 11, it is possible to prevent the undulation of the bow propagating in the circumferential direction from being hindered by the two headed screws 34 and the second holder 33. In this way, the reduction in the amplitude of the vibration caused by the strike can be suppressed. Therefore, it becomes easier for the second vibration sensor 44 to obtain the amplitude of the vibration corresponding to the strength of the strike.

[0102] In the configuration of this embodiment, in which the first holder 31 is fixed to the first cymbal 11 by screwing a nut 60 into the male thread 50a of the tubular portion 50 that protrudes from the center hole 11a of the first cymbal 11 toward the upper side X1, if there are multiple types of first cymbals with different radial sizes as the first cymbals 11, these multiple types of first cymbals can share a single first holder 31.

[0103] Furthermore, since the electronic hi-hat cymbal 1A of this embodiment has a configuration corresponding to the electronic hi-hat cymbal 1 of the first embodiment, it is possible to achieve the same effect as the electronic hi-hat cymbal 1 based on this corresponding configuration.

[0104] It should be noted here that the configuration in which the two headed screws 34 threaded into each of the screw holes 67a and 67b are arranged in the radial direction of the first cymbal 11 when the second holder 33 is fixed to the first cymbal 11 may also be utilized in the electronic hi-hat cymbal 1 of the first embodiment.

[0105] Furthermore, the terminal 69 may be of any shape as long as it can be inserted between the first cymbal 11 and the mounting portion of the first holder 31. The second holder 33 may be fixed to the first cymbal by a single headed screw.

[0106] Third embodiment FIG. 13 is an explanatory diagram of an electronic hi-hat cymbal of a third embodiment. FIG. 14 is a cross-sectional view of the electronic cymbal of FIG. 13. FIG. 15 is an exploded perspective view of the first cymbal unit of FIG. 13. The electronic hi-hat cymbal 1B of this embodiment includes an electronic musical instrument 4 supported on a commercially available hi-hat stand 2, and a module 6 (control device) electrically connected to the electronic musical instrument 4 via a cable 5. The electronic musical instrument 4, the cable 5, and the module 6 constitute an electronic cymbal set 3. The electronic musical instrument 4 includes a first cymbal unit 7 and a second cymbal unit 8.

[0107] The electronic hi-hat cymbal 1B of this embodiment is the same as the electronic hi-hat cymbal 1A of the second embodiment, except for the configuration for fixing the first holder 31 (holder) to the first cymbal 11, and the configuration for connecting the first cymbal 11 to the circuit section 43a of the touch sensor 43. Therefore, only the different parts will be explained, and other explanations will be omitted. The electronic hi-hat cymbal 1B of this embodiment has a configuration corresponding to the electronic hi-hat cymbal 1A, so the same reference numerals are used for corresponding elements.

[0108] 13 and 14, the first holder 31 is attached to the first cymbal 11 by a plurality of headed screws 32 arranged in a ring shape. Each of the headed screws 32 is made of metal or contains metal and is electrically conductive. In this embodiment, there are three headed screws 32.

[0109] As shown in Fig. 14 and Fig. 15, the first holder 31 includes an annular plate portion 45 perpendicular to the central axis L of the first cymbal 11, an outer tapered plate portion 46 inclined upward from the outer peripheral edge of the annular plate portion 45 toward the outer peripheral side toward the upper side X1, an inner tapered plate portion 47 inclined upward from the inner peripheral edge of the annular plate portion 45 toward the inner peripheral side toward the upper side X1, and an annular center plate portion 48 inclined from the upper edge of the inner tapered plate portion 47 toward the upper side X1 toward the inner peripheral side. A recess 51 recessed toward the inner peripheral side is provided in a part of the circumferential direction of the inner tapered plate portion 47. Furthermore, a notch portion 48a recessed toward the inner peripheral side corresponding to the recess 51 is provided in a part of the circumferential direction of the center plate portion 48. The central plate portion 48 is provided with an annular protruding portion 49 protruding toward the upper side X1 at its central portion, and a circular tubular portion 50 extending toward the upper side X1 from the opening edge of the central hole 11a of the protruding portion 49. In this embodiment, the tubular portion 50 does not have a male thread.

[0110] The first vibration sensor 41 is disposed on the central plate portion 48 of the first holder 31. The central plate portion 48 has three bosses 58 arranged in an annular shape at a position closer to the protruding portion 49 than the inner tapered plate portion 47. Each of the bosses 58 protrudes from the annular plate portion 49a toward the upper side X1. A screw hole into which the headed screw 32 can be engaged is provided on the upper surface of each of the bosses 58.

[0111] The first holder 31 holds the substrate 40, the first vibration sensor 41, and the coil 42a of the distance sensor 42. The circuit section 42b of the distance sensor 42 and the circuit section 43a of the touch sensor 43 are provided on the substrate 40. In order to make the first cymbal 11 a touch electrode, the first cymbal unit 7 includes a lead wire 68 that electrically connects the substrate 40 to the first cymbal 11, and a conductive terminal 69. The terminal 69 includes a connection section 69a to which the lead wire 68 is connected, and a through hole 69b into which the shaft of the headed screw 32 can be inserted.

[0112] When the first holder 31 is fixed to the first cymbal 11, the tube portion 50 of the first holder 31 is fitted into the central hole 11a of the first cymbal 11 from below. As a result, the outer circumferential surface of the tube portion 50 comes into contact with the inner wall surface of the central hole 11a of the first cymbal 11. Furthermore, the upper surface of the protruding portion 49 of the first holder 31 abuts against the opening edge of the central hole 11a of the first cymbal 11 from the lower side X2. Furthermore, each of the bosses 58 provided on the annular plate portion 49a surrounds the central hole 11a of the bell 35 at a position closer to the central hole 11a than the bow 37. When the tube portion 50 of the first holder 31 is fitted into the central hole 11a of the first cymbal 11, the terminal 69 is disposed on the upper surface of one of the three bosses 58.

[0113] Next, each of the headed screws 32 is inserted from the upper side X1 to the lower side X2 through the first cymbal 11 and screwed into the screw hole of each of the bosses 58. Here, when each of the headed screws 32 is screwed into each of the bosses 58, the shaft of the headed screw 32 is inserted into the through hole 69b of the terminal 69 in the boss 58 in which the terminal 69 is disposed. Next, when the headed screw 32 is screwed into the boss 58 and the first holder 31 is fixed to the first cymbal 11, the terminal 69 is sandwiched between the upper surface of the boss 58 and the first cymbal 11 with the headed screw 32 inserted from the through hole 69b.

[0114] As a result, the terminal 69 and the first cymbal 11 come into contact and are electrically connected, so that the first cymbal 11 functions as a touch electrode of the touch sensor 43. Furthermore, because the headed screw 32 for fixing the first holder 31 to the first cymbal 11 is conductive, the circuit portion 43a of the touch sensor 43 and the first cymbal 11 are electrically connected via the terminal 69 and the headed screw 32. This makes it possible to ensure the connection between the circuit portion 43a of the touch sensor 43 and the first cymbal 11.

[0115] Here, when the first holder 31 is fixed to the first cymbal 11, the first holder 31 does not have a portion that comes into contact with the first cymbal 11 on the outer circumferential side beyond the boss 58.

[0116] (Action and effect) In this embodiment, when the first holder 31 is fixed to the first cymbal 11, the boss 58 for firmly fixing the first holder 31 to the first cymbal 11 surrounds the central hole 11a of the bell 35 at a position closer to the central hole 11a than the bow 37. The first holder 31 does not have a portion that contacts the first cymbal 11 on the outer periphery side of the boss 58. In this manner, the first holder 31 is fixed to the first cymbal 11 at a position closer to the center of the first cymbal 11. This makes it possible to prevent the vibration of the first cymbal 11 from being disturbed when the first cymbal 11 is struck, compared to a case in which the boss 58 for fixing the first holder 31 to the first cymbal 11 surrounds the bell 35 on the outer periphery side of the bell 35. Therefore, the playing feeling when the player strikes the first cymbal 11 can be made closer to the playing feeling when a conventional cymbal is struck.

[0117] On the other hand, the first holder 31 contacts the first cymbal 11 at a position close to the center of the first cymbal 11 and the bell 35 within the opening edge of the center hole 11a of the first cymbal 11. Therefore, the first holder 31 functions as a damper for quickly attenuating the vibration of the bell 35. Since the first cymbal 11 is made of metal or contains metal, the vibration generated by hitting it tends to generate undulations, and the amplitude repeatedly increases and decreases. Therefore, there is a problem that the time of hitting, which is the time of the maximum amplitude, tends to be erroneously detected. Regarding such a problem, when the first holder 31 functions as a damper for quickly attenuating the vibration of the bell 35, it becomes easy to obtain the time of hitting based on the signal from the first vibration sensor 41.

[0118] Furthermore, in a configuration in which the first holder 31 (holder) is fixed to the first cymbal 11 by a headed screw 32 at a position close to the central hole 11a of the first cymbal 11, if there are multiple types of first cymbals with different radial sizes as the first cymbals 11, these types of first cymbals can share a single first holder 31.

[0119] Furthermore, since the electronic hi-hat cymbal 1B of the present embodiment has a configuration corresponding to the electronic hi-hat cymbal 1 of the first embodiment and the electronic hi-hat cymbal 1A of the second embodiment, it is possible to achieve the same effects as the electronic hi-hat cymbal 1 and the electronic hi-hat cymbal 1A based on this corresponding configuration.

[0120] In a configuration in which the first holder 31 (holder) is fixed to the first cymbal 11 by a headed screw 32 at a position close to the center hole 11a of the first cymbal 11, if there are two types of first cymbals with different radial sizes as the first cymbals 11, these two types of first cymbals can share a single first holder 31.

[0121] In the electronic musical instruments 4 of the first, second and third embodiments, the second cymbal 12 may have the same outer diameter as the first cymbal 11.
