Description

Picking devices and musical instruments Technical Field

[0001] This utility model relates to the field of musical instrument technology, and in particular to a plectrum device and a musical instrument. Background Technology

[0002] As society develops, people's lifestyles and needs are also increasing; for example, the demand for different types of musical instruments is growing. To meet these needs, picks have been incorporated into smart musical instruments. When using a smart musical instrument, the pick needs to be plucked in different directions, and after being plucked, the pick needs to return to its initial position to await the next pluck.

[0003] However, due to prolonged pressing and use of the paddle, it may become inaccurate in its reset position, meaning it may not return to the centered position. When the paddle is not centered, the pressing feel of the paddle will be worse, affecting the user experience. Summary of the Invention

[0004] The main purpose of this invention is to provide a paddle device that ensures the paddle assembly of the paddle device can accurately reset after being pressed.

[0014] When the paddle assembly rotates in the first direction, the first transmission unit abuts against the transmission member; when the paddle assembly rotates in the second direction, the second transmission unit abuts against the transmission member. The first direction and the second direction are opposite directions.

[0015] In some embodiments, the transmission member has a first clearance groove for accommodating the portion of the rotating shaft between the first transmission unit and the second transmission unit; so that when the paddle body is in its initial position, both the first transmission unit and the second transmission unit abut against the transmission member; and / or

[0016] The rotating shaft has a second clearance groove for the transmission component to be inserted, so that when the paddle body is in the initial position, both the first transmission unit and the second transmission unit abut against the transmission component.

[0017] In some embodiments, the transmission member has a first clearance groove, and the rotating shaft has a second clearance groove. The first clearance groove and the second clearance groove are nested together so that when the paddle body is in the initial position, both the first transmission unit and the second transmission unit abut against the transmission member.

[0018] In some embodiments, the transmission member has a first clearance groove, and the first clearance groove has a first abutment and a second abutment on both sides;

[0019] The first clearance groove is used to avoid the portion of the rotating shaft between the first transmission unit and the second transmission unit; so that when the paddle body is in the initial position, the first transmission unit abuts against the first abutment, and the second transmission unit abuts against the second abutment.

[0020] In some embodiments, the transmission member includes a rotating part, a transmission plate, and a mounting part, wherein the rotating part and the mounting part are respectively located at both ends of the transmission plate;

[0021] The rotating part is rotatably connected to the bracket assembly, the transmission plate is used to abut against the transmission part, and the mounting part is used to connect to one end of the elastic member.

[0022] In some embodiments, the transmission plate has a first corner portion and a second corner portion disposed opposite to each other, the rotating portion is connected to the first corner portion, and the mounting portion is connected to the second corner portion.

[0023] In some embodiments, the bracket assembly includes a paddle bracket and a pivot bracket, the pivot bracket being mounted on the paddle bracket and having the first rotation position.

[0024] In some embodiments, the bracket assembly includes a paddle bracket and a pivot cover, the pivot cover being fixedly connected to the paddle bracket corresponding to the transmission portion, such that the pivot cover covers the portion of the paddle assembly having the transmission portion.

[0025] In some embodiments, the number of the first rotating position, the second rotating position, the paddle assembly, the transmission member, and the elastic member is two;

[0030] This utility model also proposes a musical instrument, including a face and the aforementioned plectrum device, wherein the plectrum device is mounted on the face.

[0031] The technical solution of this utility model's paddle device includes a support assembly, a paddle assembly, a transmission component, and an elastic component. The paddle assembly and the transmission component are rotatably mounted on the support assembly. A transmission part corresponding to the transmission component is provided on the paddle assembly for abutting against the transmission component. The two ends of the elastic component are connected to the support assembly and the transmission component respectively. Thus, when the user moves the paddle assembly, the paddle assembly rotates relative to the support assembly. The transmission part acts against the transmission component, applying a force to the transmission component, causing it to rotate accordingly. This causes the elastic component to deform, and the elastic component generates an elastic force that returns the transmission component to its initial position. When the user releases the paddle assembly, the force exerted by the paddle assembly on the transmission component disappears. Under the elastic force applied by the elastic component, the transmission component rotates back to its initial position. Simultaneously, the transmission component, through its abutting action against the transmission part, drives the paddle assembly to also return to its initial position, ultimately returning both the transmission component and the paddle assembly to their respective initial positions (i.e., resetting). Therefore, the technical solution of this utility model effectively ensures that the paddle can be accurately reset after being pressed.

[0032] The technical solution of the pick device in this embodiment includes a support assembly, a pick assembly, and a detection component with a detection position. The pick assembly is rotatably connected to the support assembly. The pick assembly has a first detection part and a second detection part offset in its rotation direction. Thus, the detection position detects the passage of the first detection part when the pick assembly rotates in a first direction, and detects the passage of the second detection part when the pick assembly rotates in a second direction (i.e., the opposite direction of the first direction). The detection component generates a corresponding electrical signal based on the detected passage of the first or second detection part. When the pick device of this embodiment is applied to a musical instrument, the instrument's controller can determine the plucking behavior of the pick assembly (such as plucking direction and speed) based on the electrical signal fed back by the detection component, and control the sound-producing component to emit a corresponding sound. Therefore, the pick device of this embodiment effectively detects the plucking method (plucking direction and speed) of the pick assembly and generates a corresponding electrical signal based on the specific situation of the user plucking the pick assembly, thereby causing the musical instrument to emit a corresponding sound.

[0053] This invention primarily proposes a pick mechanism, mainly applicable to musical instruments such as electric guitars and smart guitars. The pick mechanism of this invention enables the pick assembly to accurately return to its initial position after being pressed. Furthermore, this pick mechanism can accurately detect the plucking state of the pick assembly, making the instrument's sound more closely match the user's plucking actions, thus improving the user experience. Moreover, the structure for detecting the plucking state of the pick assembly is simpler, easier to install, and lower in cost.

[0054] Referring to Figures 1 to 7, in this embodiment, the paddle device includes a support assembly 10, a paddle assembly 20, a transmission component 30, and an elastic component 40.

[0055] The bracket assembly 10 has a first rotation position 101 and a second rotation position 102. The two ends of the paddle assembly 20 are rotatably connected to the first rotation position 101 and the second rotation position 102, respectively. That is, one end of the paddle assembly 20 is rotatably connected to the first rotation position 101, and the other end is rotatably connected to the second rotation position 102. The paddle assembly 20 has a transmission part 201, and a transmission member 30 is disposed corresponding to the transmission part 201 and rotatably connected to the bracket assembly 10. The transmission member 30 is used to abut against the transmission part 201. Thus, when the paddle assembly 20 rotates, the transmission part 201 abuts against the transmission member 30, causing the transmission member 30 to rotate with the rotation of the paddle assembly 20. One end of the elastic element 40 is connected to the bracket assembly 10, and the other end of the elastic element 40 is connected to the transmission element 30. Thus, when the transmission element 30 rotates with the paddle assembly 20, the transmission element 30 will deform the elastic element 40, increasing the elastic force exerted by the elastic element 40 on the transmission element 30, so as to drive the transmission element 30 to reset (i.e. return to the initial position).

[0056] When the user moves the paddle assembly 20, the paddle assembly 20 rotates relative to the support assembly 10. The transmission part 201 of the paddle assembly 20 acts on the transmission member 30 by abutting, applying a force to the transmission member 30, causing the transmission member 30 to rotate accordingly. As a result, the transmission member 30 deforms the elastic member 40, and the elastic member 40 applies an elastic force to the transmission member 30 to return it to its initial position. When the user releases the paddle assembly 20, the force of the paddle assembly 20 on the transmission member 30 disappears. Under the elastic force of the elastic member 40 on the transmission member 30, the transmission member 30 rotates back to its initial position. At the same time, the transmission member 30, through the abutting action with the transmission part 201, drives the paddle assembly 20 to also return to its initial position. Finally, both the transmission member 30 and the paddle assembly 20 return to their respective initial positions. At this time, the deformation caused by the transmission member 30 on the elastic member 40 is also restored.

[0057] In this embodiment, the support assembly 10 is used to rotatably mount the plectrum assembly 20. The specific form of the support assembly 10 can be varied and is not particularly limited, as long as the support assembly 10 can be mounted on the musical instrument and has a first rotation position 101 and a second rotation position 102 for rotatably mounting the plectrum assembly 20. The first rotation position 101 and the second rotation position 102 can take many forms, such as both being shaft holes, rotating shafts, etc. Of course, in some implementations, the forms of the first rotation position 101 and the second rotation position 102 can also be different. For example, one can be a rotating shaft (in which case one end of the plectrum assembly 20 can be a shaft hole), and the other can be a shaft hole (in which case the other end of the plectrum assembly 20 can be a rotating shaft).

[0058] In this embodiment, the rotational connection between the paddle assembly 20 and the first rotation position 101 and the second rotation position 102 can take many forms, such as a shaft and hole fit, a shaft and bearing fit, etc. The transmission part 201 of the paddle assembly 20 can take many forms, such as block, sheet, or column, etc., without special limitation, as long as the transmission part 201 can abut against the transmission member 30 during the rotation of the support assembly 10. In this embodiment, the elastic member 40 can be an axial extension spring (e.g., a tension spring), an elastic block, an elastic rope, or other elastic devices.

[0059] The technical solution of the paddle device in this embodiment includes a bracket assembly 10, a paddle assembly 20, a transmission member 30, and an elastic member 40. The paddle assembly 20 and the transmission member 30 are rotatably mounted on the bracket assembly 10. A transmission part 201 corresponding to the transmission member 30 is provided on the paddle assembly 20 for abutting against the transmission member 30. The two ends of the elastic member 40 are respectively connected to the bracket assembly 10 and the transmission member 30. Thus, when the user moves the paddle assembly 20, the paddle assembly 20 rotates relative to the support assembly 10. The transmission part 201 acts against the transmission member 30, applying a force to the transmission member 30, causing it to rotate accordingly. This causes the elastic member 40 to deform, and the elastic member 40 generates an elastic force that returns the transmission member 30 to its initial position. When the user releases the paddle assembly 20, the force exerted by the paddle assembly 20 on the transmission member 30 disappears. Under the elastic force applied by the elastic member 40, the transmission member 30 rotates back to its initial position. Simultaneously, through the abutting action with the transmission part 201, the transmission member 30 also drives the paddle assembly 20 to return to its initial position, ultimately returning both the transmission member 30 and the paddle assembly 20 to their respective initial positions (i.e., reset). Therefore, the technical solution of this embodiment effectively ensures that the paddle can accurately reset after being pressed.

[0060] Referring to Figures 1 to 7, in some embodiments, the transmission unit 201 includes a first transmission unit 2011 and a second transmission unit 2012, which are respectively located on both sides of the rotation axis of the paddle assembly 20. The first transmission unit 2011 and the second transmission unit 2012 may be located on both sides of the same position along the axial direction of the rotation axis of the paddle assembly 20, or they may be located at different positions along the axial direction of the rotation axis. The circumferential angle between the first transmission unit 2011 and the second transmission unit 2012 along the rotation axis may be 180°, 150°, 120°, etc. When the paddle assembly 20 rotates in the first direction F1, the first transmission unit 2011 abuts against the transmission member 30; when the paddle assembly 20 rotates in the second direction F2, the second transmission unit 2012 abuts against the transmission member 30. Wherein, the first direction F1 and the second direction F2 are opposite directions, for example, the first direction F1 and the second direction F2 are clockwise and counterclockwise directions, respectively. The position where the transmission component 30 abuts against the first transmission unit 2011 is different from the position where the transmission component 30 abuts against the second transmission unit 2012.

[0061] Referring to Figures 5 and 6, when the user moves the paddle assembly 20 in the first direction F1, the paddle assembly 20 rotates in the first direction F1. At this time, the first transmission unit 2011 follows the paddle assembly 20 and rotates in the first direction F1 to abut against the transmission member 30, generating a resisting force on the transmission member 30, causing the transmission member 30 to rotate accordingly. The rotation of the transmission member 30 causes the elastic member 40 to deform, and the elastic member 40 generates an elastic force acting on the transmission member 30. When the user releases the paddle assembly 20, the transmission member 30 rotates back to its initial position under the elastic force of the elastic member 40, and the transmission member 30 generates a resisting force on the first transmission unit 2011, causing the first transmission unit 2011 to rotate in the second direction F2. Thus, the paddle assembly 20 rotates in the second direction F2 under the resisting force of the transmission member 30 to reset (i.e., return to its initial position).

[0062] Referring to Figures 5 and 7, when the user moves the paddle assembly 20 in the second direction F2, the paddle assembly 20 rotates in the second direction F2. At this time, the second transmission unit 2012 follows the paddle assembly 20 and rotates in the second direction F2 to abut against the transmission member 30, generating a resisting force on the transmission member 30, causing the transmission member 30 to rotate accordingly. The rotation of the transmission member 30 causes the elastic member 40 to deform, and the elastic member 40 generates an elastic force acting on the transmission member 30. When the user releases the paddle assembly 20, the transmission member 30 rotates back to its initial position under the elastic force of the elastic member 40, and the transmission member 30 generates a resisting force on the second transmission unit 2012, causing the second transmission unit 2012 to rotate in the first direction F1. Thus, the paddle assembly 20 rotates in the first direction F1 under the resisting force of the transmission member 30 to reset (i.e., return to its initial position).

[0063] In this embodiment, the transmission unit 201 includes a first transmission unit 2011 and a second transmission unit 2012 located on both sides of the rotation axis of the paddle assembly 20. When the paddle assembly 20 rotates in the first direction F1, the first transmission unit 2011 abuts against the transmission member 30. When the paddle assembly 20 rotates in the second direction F2, the second transmission unit 2012 abuts against the transmission member 30. Thus, regardless of whether the paddle assembly 20 rotates in the first direction F1 or the second direction F2, that is, regardless of whether the user moves the paddle assembly 20 in the first direction F1 or the second direction F2, the corresponding transmission unit can immediately abut against the transmission member 30, causing the transmission member 30 to rotate accordingly with the paddle assembly 20. This causes the elastic member 40 to deform and exert an elastic force on the transmission member 30, ensuring that when the user releases the paddle assembly 20, the elastic force of the elastic member 40 can accurately reset the paddle assembly 20.

[0064] Of course, in some other embodiments, the transmission part 201 may also include only one transmission unit. The transmission member 30 may have corresponding action parts on both sides of the transmission unit. When the paddle assembly 20 rotates in different directions, the transmission unit abuts against the action parts on different sides to make the transmission member 30 rotate accordingly.

[0065] Referring to Figures 1 to 3, in some embodiments, the paddle assembly 20 includes a paddle body 21 and a rotating shaft 22. One end of the paddle body 21 is connected to the rotating shaft 22, and the other end of the paddle body 21 is rotatably connected to a first rotating position 101. The end of the rotating shaft 22 away from the paddle body 21 is rotatably connected to a second rotating position 102. This achieves a rotatable connection between the paddle assembly 20 and the support assembly 10, with the paddle body 21 and the rotating shaft 22 rotating synchronously. The transmission part 201 of the paddle assembly 20 can be located on the rotating shaft 22 or on the paddle body 21. In this embodiment, the paddle assembly 20, by using the rotating shaft 22, better achieves a rotatable connection with the support assembly 10.

[0066] Referring to Figures 1 and 2, in some embodiments, the bracket assembly 10 may also be provided with a damper 14 at the corresponding second rotation position 102. The damper 14 is connected to the end of the rotation shaft 22 away from the paddle body 21. The damper 14 is used to provide damping effect on the rotation shaft 22, so that when the user releases the paddle assembly 20 and the paddle assembly 20 rebounds to the initial position, the rebound of the paddle assembly 20 is buffered by the damping effect of the damper 14, so as to avoid the paddle assembly 20 rebounding too fast and causing large abnormal noise and damage, thereby improving the user experience.

[0067] Referring to Figures 3, 5 to 7, in some embodiments, the transmission unit 201 is disposed on the rotating shaft 22. The transmission unit 201 includes a first transmission unit 2011 and a second transmission unit 2012. The first transmission unit 2011 and the second transmission unit 2012 are arranged at intervals along the circumference of the rotating shaft 22. For example, the first transmission unit 2011 and the second transmission unit 2012 are arranged at intervals of 180°, 150°, 120°, and 90° along the circumference of the rotating shaft 22. The first transmission unit 2011 and the second transmission unit 2012 may be arranged at intervals along the circumference of the rotating shaft 22 at the same position along the axial direction. Alternatively, the first transmission unit 2011 and the second transmission unit 2012 may be arranged at intervals along the circumference of the rotating shaft 22 at different positions along the axial direction of the rotating shaft 22. When the paddle assembly 20 rotates in the first direction F1, the first transmission unit 2011 abuts against the transmission member 30; when the paddle assembly 20 rotates in the second direction F2, the second transmission unit 2012 abuts against the transmission member 30. The first direction F1 and the second direction F2 are opposite directions, for example, the first direction F1 and the second direction F2 are clockwise and counterclockwise, respectively.

[0068] In this embodiment, by setting the transmission part 201 on the rotating shaft 22, there is sufficient space on the rotating shaft 22 for the transmission part 201 to be set, which has little impact on the installation and cooperation between the paddle assembly 20 and the bracket assembly 10. At the same time, by not setting the transmission part 201 on the paddle body 21, the structure of the paddle body 21 is made more concise, and the installation and cooperation between the paddle body 21 and the bracket assembly 10 can be more compact, thereby making the overall structure of the paddle device occupy less space. In addition, the transmission unit 201 includes a first transmission unit 2011 and a second transmission unit 2012 arranged circumferentially along the rotation axis 22. When the paddle assembly 20 rotates in the first direction F1, the first transmission unit 2011 abuts against the transmission member 30. When the paddle assembly 20 rotates in the second direction F2, the second transmission unit 2012 abuts against the transmission member 30. Thus, regardless of whether the paddle assembly 20 rotates in the first direction F1 or the second direction F2, that is, regardless of whether the user moves the paddle assembly 20 in the first direction F1 or the second direction F2, the corresponding transmission unit can immediately abut against the transmission member 30, causing the transmission member 30 to rotate accordingly with the paddle assembly 20. This causes the elastic member 40 to deform and exert an elastic force on the transmission member 30, ensuring that when the user releases the paddle assembly 20, the elastic force of the elastic member 40 can accurately reset the paddle assembly 20.

[0069] Referring to Figures 4 to 7, in some embodiments, the transmission member 30 has a first clearance groove 31, which is used to avoid the portion of the rotating shaft 22 between the first transmission unit 2011 and the second transmission unit 2012, so that when the paddle body 21 is in the initial position (i.e., the paddle assembly 20 is in the initial position), both the first transmission unit 2011 and the second transmission unit 2012 abut against the transmission member 30.

[0070] In this embodiment, by providing a first clearance groove 31 on the transmission component 30 to allow the rotating shaft 22 to pass through, the portion of the rotating shaft 22 located between the first transmission unit 2011 and the second transmission unit 2012 can be accommodated in the first clearance groove 31. In this way, the rotating shaft 22 and the transmission component 30 are partially engaged, the rotating shaft 22 and the transmission component 30 are more tightly fitted, and the rotating shaft 22 and the transmission component 30 occupy less installation space. Furthermore, by avoiding the portion of the rotating shaft 22 located between the first transmission unit 2011 and the second transmission unit 2012 through the first clearance groove 31, both the first transmission unit 2011 and the second transmission unit 2012 abut against the transmission member 30 when the paddle body 21 is in its initial position. Thus, when the paddle assembly 20 begins to rotate in any direction (first direction F1 or second direction F2), the corresponding transmission unit immediately abuts against the transmission member 30, causing the transmission member 30 to immediately follow the paddle assembly 20 in its corresponding rotation, causing the elastic member 40 to deform and generate an elastic force. Additionally, due to... When the paddle body 21 is in the initial position (i.e., the paddle assembly 20 is in the initial position), both the first transmission unit 2011 and the second transmission unit 2012 are abutting against the transmission member 30. Therefore, when the paddle assembly 20 is released after being paddled by the user, the elastic force of the elastic member 40 drives the paddle assembly 20 to rotate back to its initial position. When it returns to its initial position, the first transmission unit 2011 and the second transmission unit 2012 on both sides of the rotating shaft 22 are abutting against the transmission member 30 respectively, so that the paddle assembly 20 is stably stopped in the initial position. Therefore, it is guaranteed that the paddle assembly 20 will stably return to its initial position after being pressed.

[0071] Furthermore, in some embodiments, the first clearance groove 31 has a first abutment 32 and a second abutment 33 on both sides. When the paddle body 21 is in the initial position, the first transmission unit 2011 abuts against the first abutment 32, and the second transmission unit 2012 abuts against the second abutment 33. When the paddle assembly 20 rotates in the first direction F1, the first transmission unit 2011 rotates in the first direction F1 and applies a force to the first abutment 32, causing the transmission member 30 to rotate accordingly, so that the elastic member 40 deforms and generates an elastic force. When the paddle assembly 20 rotates in the second direction F2, the second transmission unit 2012 rotates in the second direction F2 and applies a force to the second abutment 33, causing the transmission member 30 to rotate accordingly, so that the elastic member 40 deforms and generates an elastic force.

[0072] The first abutment 32, the second abutment 33, the first transmission unit 2011, and the second transmission unit 2012 can all be planar portions, with the first transmission unit 2011 and the second transmission unit 2012 respectively abutting and fitting against the first abutment 32 and the second abutment 33. The first abutment 32 and the second abutment 33 can also be protrusions (such as protruding pillars or dots), and / or the first transmission unit 2011 and the second transmission unit 2012 can also be protrusions. Of course, the first abutment 32, the second abutment 33, the first transmission unit 2011, and the second transmission unit 2012 can also have other shapes or structures.

[0073] Referring to Figure 5, the first abutment top 32, the second abutment top 33, the first transmission unit 2011 and the second transmission unit 2012 are all planar parts. When the paddle body 21 is in the initial position, the first transmission unit 2011 is in contact with the first abutment top 32, and the second transmission unit 2012 is in contact with the second abutment top 33.

[0074] Furthermore, referring to Figures 5 to 7, in some embodiments, the abutting force of the first transmission unit 2011 on the transmission member 30 and the abutting force of the second transmission unit 2012 on the transmission member 30 are forces that drive the transmission member 30 to rotate in the same direction. When the paddle assembly 20 rotates in the first direction F1, the first transmission unit 2011 rotates in the first direction F1, and the second transmission unit 2012 separates from the second abutting top 33; when the paddle assembly 20 rotates in the second direction F2, the second transmission unit 2012 rotates in the second direction F2, and the first transmission unit 2011 separates from the first abutting top 32.

[0075] Referring to Figure 6, when the paddle body 21 rotates in the first direction F1, the edge of the end of the first transmission unit 2011 away from the second transmission unit 2012 presses against the first abutment 32, causing the transmission member 30 to rotate in the second direction F2. The first transmission unit 2011 and the first abutment 32 are no longer in contact, but change from a surface contact state to a line contact state. The second transmission unit 2012 and the second abutment 33 are directly separated.

[0076] Referring to Figure 7, when the paddle body 21 rotates in the second direction F2, the edge of the second transmission unit 2012 away from the first transmission unit 2011 presses against the transmission member 30, causing the transmission member 30 to rotate in the second direction F2. The second transmission unit 2012 and the second abutment 33 no longer fit together, but change from a surface contact state to a line contact state, and the first transmission unit 2011 and the second abutment 32 are directly separated.

[0077] Of course, in other possible implementations, when the paddle body 21 is in the initial position, the side of the first transmission unit 2011 facing the transmission member 30 is in contact with the transmission member 30, and one end of the second transmission unit 2012 is in contact with the transmission member 30; or, when the paddle body 21 is in the initial position, the side of the second transmission unit 2012 facing the transmission member 30 is in contact with the transmission member 30, and one end of the first transmission unit 2011 is in contact with the transmission member 30; or, when the paddle body 21 is in the initial position, one end of the first transmission unit 2011 is in contact with the transmission member 30, and one end of the second transmission unit 2012 is in contact with the transmission member 30.

[0078] Referring to Figures 3 and 5, in some embodiments, the rotating shaft 22 has a second clearance groove 221 for the transmission member 30 to be inserted, so that when the paddle body 21 is in the initial position, both the first transmission unit 2011 and the second transmission unit 2012 abut against the transmission member 30.

[0079] In this embodiment, by providing a second clearance groove 221 on the rotating shaft 22 to allow the transmission component 30 to pass through, the transmission component 30 is partially embedded in the second clearance groove 221. This results in a more compact fit between the rotating shaft 22 and the transmission component 30, and reduces the installation space occupied by the rotating shaft 22 and the transmission component 30. Furthermore, by partially embedding the transmission component 30 in the second clearance groove 221, both the first transmission unit 2011 and the second transmission unit 2012 abut against the transmission component 30 when the paddle body 21 is in its initial position. Thus, when the paddle assembly 20 begins to rotate in the first direction F1 or the second direction F2, the corresponding transmission unit immediately abuts against the transmission component 30, causing the transmission component 30 to immediately follow the paddle assembly 20 in its corresponding rotation, causing the elastic element 40 to deform and generate an elastic force. Additionally, since the paddle body 21 is initially... In the initial position, both the first transmission unit 2011 and the second transmission unit 2012 abut against the transmission component 30. Therefore, when the paddle assembly 20 is released after being paddled by the user, the elastic force of the elastic component 40 drives the paddle assembly 20 to rotate back to its initial position. When it returns to its initial position, the first transmission unit 2011 and the second transmission unit 2012 on both sides of the rotating shaft 22 abut against the transmission component 30 respectively, so that the paddle assembly 20 stops stably in the initial position. Therefore, it effectively ensures that the paddle assembly 20 can accurately and stably reset after being pressed.

[0080] Referring to Figures 3 and 5, in some embodiments, the transmission member 30 has a first clearance groove 31, and the rotating shaft 22 has a second clearance groove 221. The first clearance groove 31 and the second clearance groove 221 are nested together so that when the paddle body 21 is in the initial position, both the first transmission unit 2011 and the second transmission unit 2012 abut against the transmission member 30.

[0081] In this embodiment, by providing a first clearance groove 31 on the transmission component 30 to allow the rotation shaft 22 to pass, the portion of the rotation shaft 22 located between the first transmission unit 2011 and the second transmission unit 2012 can be accommodated in the first clearance groove 31. By providing a second clearance groove 221 on the rotation shaft 22 to allow the transmission component 30 to pass, the transmission component 30 is partially embedded in the second clearance groove 221. In this way, the rotation shaft 22 and the transmission component 30 are mutually engaged through the first clearance groove 31 and the second clearance groove 221, making the fit between the rotation shaft 22 and the transmission component 30 more compact and reducing the installation space occupied by the rotation shaft 22 and the transmission component 30. Furthermore, by nesting the first clearance groove 31 and the second clearance groove 221, when the paddle body 21 is in the initial position, both the first transmission unit 2011 and the second transmission unit 2012 abut against the transmission member 30. Thus, when the paddle assembly 20 starts to rotate in the first direction F1 or the second direction F2, the corresponding transmission unit immediately abuts against the transmission member 30, causing the transmission member 30 to immediately follow the paddle assembly 20 in corresponding rotation, causing the elastic member 40 to deform and generate an elastic force. When the paddle assembly 20 is released after being paddled by the user, the elastic force of the elastic member 40 drives the paddle assembly 20 to rotate back to its initial position. When it returns to its initial position, the first transmission unit 2011 and the second transmission unit 2012 on both sides of the rotating shaft 22 abut against the transmission member 30, so that the paddle assembly 20 stops stably in the initial position. Therefore, it effectively ensures that the paddle assembly 20 can accurately and stably reset after being pressed.

[0082] Of course, in some embodiments, the transmission component 30 may not have the first clearance groove 31, the rotating shaft 22 may not have the second clearance groove 221, and when the paddle body 21 is in the initial position, the first transmission unit 2011 and the second transmission unit 2012 may both abut against the transmission component 30.

[0083] In other embodiments, the paddle assembly 20 may only include the paddle body 21 and exclude the rotating shaft 22. The two ends of the paddle body 21 are rotatably connected to the first rotating position 101 and the second rotating position 102, respectively, and the transmission part 201 is located on the paddle body 21.

[0084] Referring to Figures 4 to 7, in some embodiments, the transmission member 30 includes a rotating part 34, a transmission plate 35, and a mounting part 36. The rotating part 34 and the mounting part 36 are located at opposite ends of the transmission plate 35. The rotating part 34 is rotatably connected to the bracket assembly 10. The transmission plate 35 abuts against the transmission part 201, and the mounting part 36 is connected to one end of the elastic member 40. In this embodiment, when the user moves the paddle assembly 20, the paddle assembly 20 rotates, and the transmission part 201 abuts against the transmission plate 35, causing the transmission plate 35 to rotate around the rotating part 34 at one end. The mounting part 36 at the other end of the transmission plate 35 then causes one end of the elastic member 40 to displace accordingly, causing the elastic member 40 to deform accordingly, thereby applying an elastic force to the mounting part 36.

[0085] The rotating part 34 can be a shaft, a shaft hole, etc. The rotating connection between the rotating part 34 and the bracket assembly 10 can be through the rotating fit between the shaft and the shaft hole, or through the rotating fit between the shaft and the circular groove, etc. The connection between the mounting part 36 and the elastic element 40 can be that the elastic element 40 is a tension spring, with one end of the tension spring hanging on the mounting part 36, or the elastic element 40 is an elastic rope, with one end of the elastic rope tied to the mounting part 36, etc.

[0086] In this embodiment, the rotating part 34 at one end of the transmission plate 35 is rotatably connected to the bracket assembly 10, and the mounting part 36 at the other end of the transmission plate 35 is connected to the elastic member 40. Therefore, whether the transmission part 201 rotates by abutting the transmission plate 35 through the first transmission unit 2011 or the second transmission unit 2012, the transmission plate 35 rotates around the rotating part 34 in the same direction, which will cause the elastic member 40 to deform in the same direction, so that the elastic member 40 applies the same elastic force to the transmission plate 35. In this way, only one elastic member 40 is needed to reset the transmission plate 35, that is, to reset the paddle assembly 20. This makes the paddle device use fewer parts, has a simpler structure, better reliability, and lower cost.

[0087] In some embodiments, the transmission plate 35 has a first corner portion 351 and a second corner portion 352 disposed opposite to each other, a rotating portion 34 is connected to the first corner portion 351, and a mounting portion 36 is connected to the second corner portion 352. The first corner portion 351 and the second corner portion 352 can be a pair of opposite corners of the transmission plate 35, or a pair of adjacent corners of the transmission plate 35. The rotating portion 34 and the mounting portion 36 can be integrally formed with the transmission plate 35, or they can be detachably connected to the transmission plate 35.

[0088] Referring to Figures 1 and 2, in some embodiments, the support assembly 10 includes a paddle bracket 11 and a pivot bracket 12. The pivot bracket 12 is mounted on the paddle bracket 11 and has a first rotation position 101. The paddle bracket 11 has a second rotation position 102. One end of the paddle assembly 20 is rotatably connected to the first rotation position 101 of the pivot bracket 12, and the other end is rotatably connected to the second rotation position 102 of the paddle bracket 11. The pivot bracket 12 and the paddle bracket 11 can be detachably connected or integrally formed.

[0089] Referring to Figures 1 and 2, in some embodiments, the support assembly 10 includes a paddle bracket 11 and a pivot cover 13. The pivot cover 13 is fixedly connected to the paddle bracket 11 corresponding to the transmission part 201, so that the pivot cover 13 covers the portion of the paddle assembly 20 with the transmission part 201. By covering the portion of the paddle assembly 20 with the transmission part 201 with the pivot cover 13, the mating structure between the transmission part 201 and the transmission component 30 is covered, making the overall appearance of the paddle device simpler. At the same time, the pivot cover 13 can also limit the rotation shaft 22 and the transmission component 30 of the paddle assembly 20, preventing the rotation shaft 22 and the transmission component 30 from deviating from their positions and ensuring the stability of the paddle device structure.

[0090] Referring to Figures 1 and 2, in some embodiments, the number of first rotating positions 101, second rotating positions 102, paddle assembly 20, transmission member 30, and elastic member 40 are all two. The two first rotating positions 101 are located in the middle of the support assembly 10, and the two second rotating positions 102 are located at both ends of the support assembly 10. When the support assembly 10 includes a paddle bracket 11 and a rotating shaft bracket 12, the rotating shaft bracket 12 is located in the middle of the paddle bracket 11, the two first rotating positions 101 are located at both ends of the rotating shaft bracket 12, and the two second rotating positions 102 are located at both ends of the paddle bracket 11. The two paddle assemblies 20 are rotatably connected to the two first rotating positions 101 and the two second rotating positions 102, respectively. That is, one paddle assembly 20 is rotatably connected between one first rotating position 101 and one second rotating position 102, and the other paddle assembly 20 is rotatably connected between another first rotating position 101 and another second rotating position 102. The two paddle assemblies 20 are arranged sequentially along the length of the support assembly 10. Two transmission components 30 are respectively engaged with the transmission parts 201 of the two paddle assemblies 20, and two elastic components 40 are respectively connected to the two transmission components 30 and the two ends of the support assembly 10. In this way, when the paddle of any paddle assembly 20 is plucked or pressed, it can be accurately reset by the elastic force of its corresponding elastic component 40. In addition, the paddle device has two paddle assemblies 20. When plucking, the user can choose to pluck either one of the paddle assemblies 20 in the first direction or the second direction, or he / she can choose to pluck both paddle assemblies 20 in the first direction or the second direction at the same time. In this way, the instrument can produce different rhythmic sounds (such as different rhythmic chords) according to different plucking methods, making the chordal sound of the instrument richer.

[0091] Of course, in some other embodiments, the number of the first rotation position 101, the second rotation position 102, the paddle assembly 20, the transmission member 30, and the elastic member 40 may be only one, that is, the paddle device has only one paddle assembly 20; or the number of the first rotation position 101, the second rotation position 102, the paddle assembly 20, the transmission member 30, and the elastic member 40 may be three or more, that is, the paddle device has three or more paddle assemblies 20.

[0092] Referring to Figures 1 to 3, and Figures 8 and 9, in this embodiment, the paddle device includes a support assembly 10, a paddle assembly 20, and a detection assembly 50. The support assembly 10 has a first rotation position 101 and a second rotation position 102. The two ends of the paddle assembly 20 are rotatably connected to the first rotation position 101 and the second rotation position 102, respectively; that is, the paddle assembly 20 is rotatably connected to the support assembly 10. The paddle assembly 20 has a first detection part 23 and a second detection part 24, which are offset from each other in the rotation direction of the paddle assembly 20.

[0093] The staggered arrangement of the first detection unit 23 and the second detection unit 24 in the rotation direction of the paddle assembly 20 means that the first detection unit 23 and the second detection unit 24 are located in two different angular ranges in the rotation direction of the paddle assembly 20. For example, the first detection unit 23 is located in the 0° to 40° angular range in the rotation direction of the paddle assembly 20, and the second detection unit 24 is located in the 50° to 90° angular range in the rotation direction of the paddle assembly 20; that is, the projections of the first detection unit 23 and the second detection unit 24 in the plane perpendicular to the rotation axis of the paddle assembly 20 do not coincide. The first detection unit 23 and the second detection unit 24 can be distributed on the same circumference or on different circumferences.

[0094] The detection component 50 has a detection position 501. When the paddle assembly 20 rotates in a first direction, the detection position 501 is used to detect the first detection part 23; when the paddle assembly 20 rotates in a second direction, the detection position 501 is used to detect the second detection part 24. The first and second directions are opposite directions, for example, clockwise and counterclockwise, respectively. The detection component 50 can be connected and mounted on the bracket assembly 10.

[0095] When the user moves the paddle assembly 20 in the first direction, the paddle assembly 20 rotates in the first direction, and the first detection unit 23 passes through the detection position 501 of the detection assembly 50. The detection position 501 of the detection assembly 50 detects the first detection unit 23 and generates a corresponding electrical signal based on the specific circumstances of the first detection unit 23 passing through the detection position 501 (such as the speed at which it passes). When the user moves the paddle assembly 20 in the second direction, the paddle assembly 20 rotates in the second direction, and the second detection unit 24 passes through the detection position 501 of the detection assembly 50. The detection position 501 of the detection assembly 50 detects the second detection unit 24 and generates a corresponding electrical signal based on the specific circumstances of the second detection unit 24 passing through the detection position 501 (such as the speed at which it passes). When the paddle device is installed on a musical instrument, the instrument's controller can determine the paddle movement of the paddle assembly 20 (such as the paddle direction and speed) based on the electrical signal generated by the detection assembly 50, thereby controlling the sound-producing component to emit the corresponding sound.

[0096] For example, in some embodiments, as shown in FIG10, the detection component 50 includes a detection circuit 511. When the first detection unit 23 passes the detection position 501, the detection circuit 511 generates a first detection signal; when the second detection unit 24 passes the detection position 501, the detection circuit 511 generates a second detection signal. When installed on a musical instrument, the instrument's controller can determine the direction of plectrum assembly 20 based on whether the detection signal generated by the detection circuit 511 is the first or the second detection signal.

[0097] The technical solution of the plectrum device in this embodiment includes a support assembly 10, a plectrum assembly 20, and a detection component 50 with a detection position 501. The plectrum assembly 20 is rotatably connected to the support assembly 10. The plectrum assembly 20 has a first detection part 23 and a second detection part 24 that are offset in its rotation direction. Thus, the detection position 501 detects the passage of the first detection part 23 when the plectrum assembly 20 rotates in a first direction, and detects the passage of the second detection part 24 when the plectrum assembly 20 rotates in a second direction (i.e., the opposite direction of the first direction). The detection component 50 generates a corresponding electrical signal based on the detected passage of the first detection part 23 or the second detection part 24. When the plectrum device of this embodiment is applied to a musical instrument, the instrument's controller can determine the plectrum assembly 20's plectrum movement (such as plectrum direction, plectrum speed, etc.) based on the electrical signal fed back by the detection component 50, so as to control the sound-producing component to emit a corresponding sound. Therefore, the pick device of this embodiment effectively detects the plucking method (plucking direction and plucking speed) of the pick assembly 20, and generates a corresponding electrical signal according to the specific situation of the user plucking the pick assembly 20, thereby causing the instrument to produce a corresponding sound. Furthermore, the pick device of this embodiment only consists of a first detection unit 23 and a second detection unit 24 that are staggered, and a detection component 50 with a detection position 501 to realize the plucking detection of the pick assembly 20. The structure is simpler, the installation is more convenient, and the cost of the pick device and the instrument is reduced.

[0098] Referring to Figures 1 to 3 and Figure 8, in some embodiments, the paddle assembly 20 includes a paddle body 21 and a rotating shaft 22 connected to the paddle body 21. One end of the paddle body 21, away from the rotating shaft 22, is rotatably connected to a first rotation position 101, and the other end of the rotating shaft 22, away from the paddle body 21, is rotatably connected to a second rotation position 102. When the user moves the paddle assembly 20, the paddle body 21 and the rotating shaft 22 rotate synchronously.

[0099] In this embodiment, the first detection unit 23 and the second detection unit 24 are both disposed on the rotating shaft 22 and arranged at intervals along the length of the rotating shaft 22 (i.e., the first detection unit 23 and the second detection unit are not on the same circumference of the rotating shaft 22). By disposing of the first detection unit 23 and the second detection unit 24 on the rotating shaft 22, there is sufficient space on the rotating shaft 22 for disposing of the first detection unit 23 and the second detection unit 24, which has little impact on the installation and fit between the paddle assembly 20 and the bracket assembly 10. At the same time, by not disposing of the first detection unit 23 and the second detection unit 24 on the paddle body 21, the structure of the paddle body 21 is made more compact, and the installation and fit between the paddle body 21 and the bracket assembly 10 can be more compact, thereby making the overall structure of the paddle device occupy less space.

[0100] Of course, in other embodiments, the first detection unit 23 and the second detection unit 24 may both be disposed on the paddle body 21 and arranged at intervals along the length of the paddle body 21; or, the first detection unit 23 may be disposed on the paddle body 21 and the second detection unit 24 may be disposed on the rotation shaft 22. Of course, in some other embodiments, the first detection unit 23 and the second detection unit 24 may also be disposed on the same circumference of the rotation shaft 22 or the paddle body 21.

[0101] In some other embodiments, the detection position 501 includes a detection groove, and the first detection part 23 and the second detection part 24 are located on the same circumference, that is, the first detection part 23 and the second detection part 24 are arranged at intervals along the rotation direction of the paddle assembly 20. For example, the detection groove is located in the interval region between the first detection part 23 and the second detection part 24. Thus, when the paddle assembly 20 rotates in the first direction, the first detection part 23 rotates towards the detection groove to gradually pass through the detection groove, and when the paddle assembly 20 rotates in the second direction, the second detection part 24 rotates towards the detection groove to gradually pass through the detection groove.

[0102] In this embodiment, the first detection unit 23 and the second detection unit 24 can have different structures. Therefore, when the first detection unit 23 and the second detection unit 24 pass through the detection groove, the detection component 50 will generate signals of different magnitudes. The detection component 50 can then distinguish whether it is the first detection unit 23 or the second detection unit 24 that has passed through the detection groove, thereby determining the rotation direction of the paddle assembly 20. For example, the first detection unit 23 and the second detection unit 24 may extend into the detection groove to different depths. For instance, when the first detection unit 23 passes through the detection groove, it may only extend to the opening of the groove, while when the second detection unit 24 passes through the groove, it may extend to the bottom of the groove. In this way, the electrical signal generated by the detection component 50 when the first detection unit 23 passes through the groove will differ in magnitude from the electrical signal generated when the second detection unit 24 passes through the groove. Based on the difference in electrical signal magnitude, it can be confirmed whether it is the first detection unit 23 or the second detection unit 24 that has passed through the groove, thereby determining the rotation direction of the paddle assembly 20. Of course, the first detection unit 23 and the second detection unit 24 can also have other different structural designs.

[0103] In this embodiment, the first detection unit 23 and the second detection unit 24 are distributed on the same circumference of the rotation axis of the rotating shaft 22 or the rotation axis of the paddle body 21. Thus, when the paddle assembly 20 is rotated, the movement trajectories of the first detection unit 23 and the second detection unit 24 are on the same circumferential trajectory. Therefore, the detection assembly 50 only needs to set a detection groove corresponding to the circumferential trajectory to complete the detection of the movement of the first detection unit 23 and the second detection unit 24, making the structure of the detection assembly 50 simpler and the cost lower.

[0104] Referring to FIG10, in some embodiments, the detection component 50 includes a detection circuit 511 and a transmitter 512 and a receiver 513 electrically connected to the detection circuit 511. The transmitter 512 and the receiver 513 are respectively located on both sides of the detection position 501, so that when the first detection unit 23 and the second detection unit 24 pass through the detection position 501, the detection circuit 511 generates a detection signal. In this embodiment, when the first detection unit 23 or the second detection unit 24 passes through the detection position 501, the first detection unit 23 or the second detection unit 24 interferes with the transmission signal of the transmitter 512 (e.g., by blocking it), causing the signal received by the receiver 513 to change (reduced or disappear). At this time, the detection circuit 511 can determine that a detection unit has passed through the detection position 501, and determine whether it is the first detection unit 23 or the second detection unit 24 that has passed through the detection position 501, thereby generating a corresponding detection signal.

[0105] In some embodiments, the transmitter 512 may include a light generator, and the receiver 513 may include a light receiver; that is, the transmitter 512, the receiver 513, and the detection circuit 511 constitute a photoelectric sensor. In some embodiments, the light generator and the light receiver may be respectively disposed on two opposite inner walls of the detection groove. Of course, in other embodiments, the transmitter 512 and the receiver 513 may be other types of components.

[0106] Referring to Figures 2 and 9, in some embodiments, the detection position 501 includes a first detection groove 5011 and a second detection groove 5012 arranged along the length direction of the paddle assembly 20. A first detection part 23 and a second detection part 24 are arranged at intervals corresponding to the first detection groove 5011 and the second detection groove 5012, respectively, so that the first detection groove 5011 is used to detect the first detection part 23, and the second detection groove 5012 is used to detect the second detection part 24. Referring to Figures 3 and 8, in this embodiment, the first detection part 23 and the second detection part 24 are located at different positions along the length direction of the paddle assembly 20, with the first detection part 23 corresponding to the first detection groove 5011 and the second detection part 24 corresponding to the second detection groove 5012. When the paddle assembly 20 rotates in the first direction, the first detection unit 23 passes through the first detection groove 5011, and the detection component 50 generates a corresponding signal based on the first detection groove 5011 being triggered by the first detection unit 23, thereby determining that the paddle assembly 20 is being paddled in the first direction; when the paddle assembly 20 rotates in the second direction, the second detection unit 24 passes through the second detection groove 5012, and the detection component 50 generates a corresponding signal based on the second detection groove 5012 being triggered by the second detection unit 24, thereby determining that the paddle assembly 20 is being paddled in the second direction.

[0107] In this embodiment, the detection position 501 adopts a scheme of first detection slots 5011 and second detection slots 5012 arranged along the length of the paddle assembly 20. The first detection slots 5011 and second detection slots 5012 are used to detect the first detection part 23 and the second detection part 24, respectively. In this way, the detection assembly 50 can clearly determine the direction of the paddle assembly 20 being plucked based on the triggering of the first detection slots 5011 and second detection slots 5012, making the detection more accurate and simple. Furthermore, based on the duration of the triggering of the first detection slots 5011 and second detection slots 5012, the speed of the first detection part 23 passing through the first detection slot 5011 and the speed of the second detection part 24 passing through the second detection slot 5012 can be determined, thus determining the speed at which the paddle assembly 20 is plucked. Therefore, the detection assembly 50 generates a corresponding electrical signal to the musical instrument based on the specific triggering of the first detection slots 5011 and second detection slots 5012. The musical instrument then emits a sound of corresponding size and / or rhythm based on the electrical signal, enabling the musical instrument to accurately emit a sound of corresponding rhythm or size according to the paddle assembly 20.

[0108] Referring to FIG11, in some embodiments, the detection component 50 includes a detection circuit 511 and a transmitter 512 and a receiver 513 electrically connected to the detection circuit 511. The transmitter 512 includes a first transmitting unit 5121 and a second transmitting unit 5122, and the receiver 513 includes a first receiving unit 5131 and a second receiving unit 5132. The first transmitting unit 5121 and the first receiving unit 5131 are respectively located on both sides of the first detection groove 5011 (e.g., on the inner walls of both sides, or on the top or end of both sides), and the second transmitting unit 5122 and the second receiving unit 5132 are respectively located on both sides of the second detection groove 5012. The first receiving unit 5131 receives the signal emitted by the first transmitting unit 5121, and the second receiving unit 5132 receives the signal emitted by the second transmitting unit 5122. The first transmitting unit 5121 and the second transmitting unit 5122 can be light generating units, and the first receiving unit 5131 and the second receiving unit 5132 can be light receiving units.

[0109] In this embodiment, when the paddle assembly 20 rotates in the first direction, the first detection unit 23 passes through the first detection slot 5011, and the signal received by the first receiving unit 5131 from the first transmitting unit 5121 decreases or the first receiving unit 5131 fails to receive the signal from the first transmitting unit 5121. At this time, the detection circuit 511 can know that the first detection unit 23 has passed through the first detection slot 5011 based on the signal fed back by the first receiving unit 5131. Similarly, when the paddle assembly 20 rotates in the second direction, the second detection unit 24 passes through the second detection slot 5012, and the signal received by the second receiving unit 5132 from the second transmitting unit 5122 decreases or the second receiving unit 5132 fails to receive the signal from the second transmitting unit 5122. At this time, the detection circuit 511 can know that the second detection unit 24 has passed through the second detection slot 5012 based on the signal fed back by the second receiving unit 5132. Thus, based on the signal changes fed back by the first receiving unit 5131 and the second receiving unit 5132, the detection circuit 511 can determine the situation of the first detection unit 23 passing through the first detection slot 5011 (such as the duration) and the situation of the second detection unit 24 passing through the second detection slot 5012 (such as the duration). In this way, the plectrum assembly 20 can be determined in terms of plectrum direction and speed. The detection circuit 511 can then generate a corresponding electrical signal to the instrument controller based on the specific plectrum assembly 20 plectrum situation (plectrum direction and plectrum speed). As a result, the instrument emits a sound of corresponding size and / or rhythm based on the electrical signal, so that the instrument emits a sound of corresponding rhythm or size based on the plectrum assembly 20 plectrum situation.

[0110] Referring to Figures 3 and 8, in some embodiments, the first detection unit 23 includes a first blocking part 231, and the second detection unit 24 includes a second blocking part 241. The first blocking part 231 and the second blocking part 241 are offset in the rotation direction of the paddle assembly 20. The first blocking part 231 includes a first sub-blocking part 2311, a second sub-blocking part 2312, and a first gap 2313, which is located between the first sub-blocking part 2311 and the second sub-blocking part 2312. When the paddle assembly 20 rotates along the first direction, the first sub-blocking part 2311, the first gap 2313, and the second sub-blocking part 2312 successively enter the detection position 501. When the paddle assembly 20 is rotated in the first direction, the first sub-blocking part 2311 first enters the detection position 501. At this time, the detection assembly 50 generates a blocking signal. When the first sub-blocking part 2311 passes through the detection position 501, the first gap 2313 enters the detection position 501, and the detection assembly 50 does not generate a blocking signal. Then, when the first gap 2313 passes through the detection position 501, the second sub-blocking part 2312 enters the detection position 501, and the detection assembly 50 generates a blocking signal again. Finally, when the second sub-blocking part 2312 passes through the detection position 501, the detection assembly 50 does not generate a blocking signal.

[0111] In this embodiment, the detection component 50 can calculate the rotation speed of the pick assembly 20 (i.e., the speed at which the user plucks the pick assembly 20) based on the duration of the first obstruction signal and the width of the first sub-obstruction portion 2311; the detection component 50 can also calculate the rotation speed of the pick assembly 20 based on the time interval between the first and second obstruction signals, the width of the first sub-obstruction portion 2311, and the width of the first gap 2313; the detection component 50 can also calculate the rotation speed of the pick assembly 20 based on the time interval between the disappearance of the first obstruction signal and the appearance of the second obstruction signal, and the width of the first gap 2313, etc. When the pick assembly 20 is applied to a musical instrument, the detection component 50 can send the calculated rotation speed of the pick assembly 20 (i.e., the plucking speed of the pick assembly 20) to the instrument's controller, so that the controller can control the output of the corresponding sound (the sound corresponding to the volume and rhythm) based on the plucking speed of the pick assembly 20.

[0112] Referring to Figures 3, 8, and 9, in some embodiments, the first detection unit 23 includes a first blocking part 231, and the second detection unit 24 includes a second blocking part 241. The first blocking part 231 and the second blocking part 241 are offset in the rotation direction of the paddle assembly 20. The second blocking part 241 includes a third sub-blocking part 2411, a fourth sub-blocking part 2412, and a second gap 2413, with the second gap 2413 located between the third sub-blocking part 2411 and the fourth sub-blocking part 2412. When the paddle assembly 20 rotates in the second direction, the third sub-blocking part 2411, the second gap 2413, and the fourth sub-blocking part 2412 successively enter the detection position 501. When the toggle assembly 20 is rotated in the second direction, the third sub-blocking part 2411 first enters the detection position 501. At this time, the detection assembly 50 generates a blocking signal. When the third sub-blocking part 2411 passes through the detection position 501, the second gap 2413 enters the detection position 501, and the detection assembly 50 does not generate a blocking signal. Then, when the second gap 2413 passes through the detection position 501, the fourth sub-blocking part 2412 enters the detection position 501, and the detection assembly 50 generates a blocking signal again. Finally, when the fourth sub-blocking part 2412 passes through the detection position 501, the detection assembly 50 does not generate a blocking signal.

[0113] In this embodiment, the detection component 50 can calculate the rotation speed of the pick assembly 20 (i.e., the speed at which the user plucks the pick assembly 20) based on the duration of the first obstruction signal and the width of the third sub-obstruction part 2411; the detection component 50 can also calculate the rotation speed of the pick assembly 20 based on the time interval between the first and second obstruction signals, the width of the third sub-obstruction part 2411, and the width of the second gap 2413; the detection component 50 can also calculate the rotation speed of the pick assembly 20 based on the time interval between the disappearance of the first obstruction signal and the appearance of the second obstruction signal, and the width of the second gap 2413; and so on. When the pick assembly 20 is applied to a musical instrument, the detection component 50 can send the calculated rotation speed of the pick assembly 20 (i.e., the plucking speed of the pick assembly 20) to the instrument's controller, so that the controller can control the output of the corresponding sound (the sound corresponding to the volume and rhythm) based on the plucking speed of the pick assembly 20.

[0114] Referring to Figures 9 to 11, in some embodiments, the detection position 501 includes a first detection slot 5011 and a second detection slot 5012 arranged along the length of the paddle assembly 20. A first detection part 23 and a second detection part 24 are arranged at intervals corresponding to the first detection slot 5011 and the second detection slot 5012, respectively. The first detection slot 5011 is used to detect the first detection part 23, and the second detection slot 5012 is used to detect the second detection part 24. The detection assembly 50 includes a detection circuit 511 and a transmitter 512 and a receiver 513 electrically connected to the detection circuit 511. The transmitter 512 includes a first transmitting unit 5121 and a second transmitting unit 5122, and the receiver 513 includes a first receiving unit 5131 and a second receiving unit 5132. The first transmitting unit 5121 and the first receiving unit 5131 are located on both sides of the first detection slot 5011, and the second transmitting unit 5122 and the second receiving unit 5132 are located on both sides of the second detection slot 5012. In this embodiment, the first detection unit 23 includes a first blocking part 231, and the second detection unit 24 includes a second blocking part 241. The first blocking part 231 and the second blocking part 241 are offset in the rotation direction of the paddle assembly 20. The first blocking part 231 includes a first sub-blocking part 2311, a second sub-blocking part 2312, and a first gap 2313, which is located between the first sub-blocking part 2311 and the second sub-blocking part 2312. The second blocking part 241 includes a third sub-blocking part 2411, a fourth sub-blocking part 2412, and a second gap 2413, which is located between the third sub-blocking part 2411 and the fourth sub-blocking part 2412.

[0115] In this embodiment, when the paddle assembly 20 rotates along the first direction, the first sub-blocking part 2311, the first gap 2313, and the second sub-blocking part 2312 successively enter the first detection groove 5011. When the first sub-blocking part 2311 enters the first detection groove 5011, a blocking signal is generated. The detection circuit 511 determines, based on the signal fed back by the first receiving unit 5131, that the signal emitted by the first transmitting unit 5121 is blocked, thereby generating a blocking signal. When the first sub-blocking part 2311 passes through the first detection groove 5011, and then the first gap 2313 enters the first detection groove 5011, the detection circuit 511 determines, based on the signal fed back by the first receiving unit 5131, that the signal emitted by the first transmitting unit 5121 is not blocked, and no blocking signal is generated. When the first gap 2313 passes through the first detection slot 5011, causing the second sub-blocking part 2312 to enter the first detection slot 5011, the detection circuit 511 determines, based on the signal fed back by the first receiving unit 5131, that the signal emitted by the first transmitting unit 5121 is blocked again, thereby generating a blocking signal again. Finally, when the second sub-blocking part 2312 passes through the first detection slot 5011, the detection circuit 511 determines, based on the signal fed back by the first receiving unit 5131, that the signal emitted by the first transmitting unit 5121 is not blocked, and no blocking signal is generated.

[0116] As the paddle assembly 20 rotates in the second direction, the third sub-blocking part 2411, the second gap 2413, and the fourth sub-blocking part 2412 successively enter the second detection groove 5012. When the third sub-blocking part 2411 enters the second detection groove 5012, a blocking signal is generated. The detection circuit 511 determines, based on the signal fed back by the second receiving unit 5132, that the signal emitted by the second transmitting unit 5122 is blocked, thus generating a blocking signal. When the third sub-blocking part 2411 passes through the second detection groove 5012, and then the second gap 2413 enters the second detection groove 5012, the detection circuit 511 determines, based on the signal fed back by the second receiving unit 5132, that the signal emitted by the second transmitting unit 5122 is not blocked, and no blocking signal is generated. When the second gap 2413 passes through the second detection slot 5012, causing the fourth sub-blocking part 2412 to enter the second detection slot 5012, the detection circuit 511 determines, based on the signal fed back by the second receiving unit 5132, that the signal emitted by the second transmitting unit 5122 is blocked again, thereby generating a blocking signal again. Finally, when the fourth sub-blocking part 2412 passes through the second detection slot 5012, the detection circuit 511 determines, based on the signal fed back by the second receiving unit 5132, that the signal emitted by the second transmitting unit 5122 is not blocked, and no blocking signal is generated.

[0117] In this embodiment, the detection circuit 511 can determine whether the detection part passes through the first detection slot 5011 or the second detection slot 5012 based on the feedback electrical signals from the first receiving unit 5131 and the second receiving unit 5132, thereby determining the direction in which the plectrum assembly 20 is plucked. Then, based on the feedback electrical signals from the first receiving unit 5131 and the second receiving unit 5132, as well as the dimensions of each part of the first blocking part 231 and the second blocking part 241, the rotational speed (i.e., the speed at which it is plucked) of the plectrum assembly 20 can be calculated. This allows for accurate feedback of the plucking direction and speed of the plectrum assembly 20 to the instrument's controller, enabling the instrument's controller to control the instrument to produce corresponding sounds (sounds corresponding to volume and rhythm).

[0118] Referring to Figures 3 and 8, in some embodiments, the first detection unit 23 further includes a third blocking part 232, with a third gap 25 between the third blocking part 232 and the first blocking part 231; in some embodiments, the third blocking part 232 may be disposed opposite to the second blocking part 241, that is, the third gap 25 is located between the third blocking part 232 and the first sub-blocking part 2311. Thus, when the paddle assembly 20 rotates in the second direction, when the second blocking part 241 passes the detection position 501, the third blocking part 232 also just passes the detection position 501. The detection assembly 50 can determine that the rotation direction of the paddle assembly 20 is the second direction based on the simultaneous detection of the second blocking part 241 and the third blocking part 232 passing the detection position 501; conversely, it can determine that the rotation mode of the paddle assembly 20 is the first direction. Specifically, the detection position 501 includes a first detection groove 5011 and a second detection groove 5012 arranged along the length of the paddle assembly 20. A first detection part 23 and a second detection part 24 are arranged at intervals corresponding to the first detection groove 5011 and the second detection groove 5012, respectively. The first detection groove 5011 is used to detect the first detection part 23, and the second detection groove 5012 is used to detect the second detection part 24. When the paddle assembly 20 rotates in the second direction, when the second blocking part 241 passes through the second detection groove 5012, the third blocking part 232 also just passes through the first detection groove 5011. Based on the fact that the second detection groove 5012 sequentially generates two blocking signals, and the first detection groove 5011 continuously generates a blocking signal, the detection assembly 50 can determine that the rotation direction of the paddle assembly 20 is the second direction.

[0119] Referring to Figures 3 and 8, in some embodiments, the second detection unit 24 further includes a fourth blocking part 242, with a fourth gap 26 between the fourth blocking part 242 and the second blocking part 241. In some embodiments, the fourth blocking part 242 may be disposed opposite to the first blocking part 231, that is, the fourth gap 26 is located between the fourth blocking part 242 and the third sub-blocking part 2411. Thus, when the paddle assembly 20 rotates in the first direction, when the first blocking part 231 passes the detection position 501, the fourth blocking part 242 also just passes the detection position 501. The detection assembly 50 can determine that the rotation direction of the paddle assembly 20 is the first direction based on the simultaneous detection of the first blocking part 231 and the fourth blocking part 242 passing the detection position 501; otherwise, it can determine that the rotation mode of the paddle assembly 20 is the second direction. Specifically, the detection position 501 includes a first detection groove 5011 and a second detection groove 5012 arranged along the length of the paddle assembly 20. A first detection part 23 and a second detection part 24 are arranged at intervals corresponding to the first detection groove 5011 and the second detection groove 5012, respectively. The first detection groove 5011 is used to detect the first detection part 23, and the second detection groove 5012 is used to detect the second detection part 24. When the paddle assembly 20 rotates in the first direction, when the first blocking part 231 passes through the first detection groove 5011, the fourth blocking part 242 also just passes through the second detection groove 5012. Based on the fact that the first detection groove 5011 sequentially generates two blocking signals and the second detection groove 5012 continuously generates blocking signals, the detection assembly 50 can determine that the rotation direction of the paddle assembly 20 is the first direction.

[0120] In some other embodiments, the third blocking portion 232 may also be a second sub-blocking portion 2312 located near the first blocking portion 231, that is, the third gap 25 is located between the third blocking portion 232 and the second sub-blocking portion 2312; the fourth blocking portion 242 may also be a fourth sub-blocking portion 2412 located near the second blocking portion 241, that is, the fourth gap 26 is located between the fourth blocking portion 242 and the fourth sub-blocking portion 2412.

[0121] Referring to Figure 12, in some embodiments, when the first blocking portion 231 includes a first gap 2313 and the second blocking portion 241 includes a second gap 2413, the width of the first gap 2313 is greater than or less than the width of the second gap 2413 (the figure takes the example where the width of the first gap 2313 is less than the width of the second gap 2413), that is, the widths of the first gap 2313 and the second gap 2413 are not equal. Thus, when the paddle assembly 20 is rotated in the first direction, the proportion of time the first gap 2313 passes the detection position 501 relative to the total time the first blocking portion 231 passes the detection position 501 will differ from the proportion of time the second gap 2413 passes the detection position 501 relative to the total time the second blocking portion 241 passes the detection position 501 when the paddle assembly 20 is rotated in the second direction. The detection component 50 can distinguish whether the part passing through the detection position 501 is the first blocking part 231 or the second blocking part 241 based on the proportion of the time the gap passes through the detection position 501 to the total time the blocking part passes through the detection position 501.

[0122] In some embodiments, when the first blocking portion 231 includes a first sub-blocking portion 2311 and the second blocking portion 241 includes a third sub-blocking portion 2411, the first sub-blocking portion 2311 is larger or smaller than the third sub-blocking portion 2411, that is, the sizes of the first sub-blocking portion 2311 and the third sub-blocking portion 2411 are not equal. In this embodiment, this mainly refers to the unequal widths (i.e., the dimensions in their rotational direction) of the first sub-blocking portion 2311 and the third sub-blocking portion 2411. Thus, when the toggle assembly 20 rotates in the first direction, the proportion of time the first sub-blocking portion 2311 passes the detection position 501 relative to the total time the first blocking portion 231 passes the detection position 501 will differ from the proportion of time the third sub-blocking portion 2411 passes the detection position 501 relative to the total time the second blocking portion 241 passes the detection position 501 when the toggle assembly 20 rotates in the second direction. The detection component 50 can distinguish whether the part passing through the detection position 501 is the first occluding part 231 or the second occluding part 241 based on the proportion of the time the sub-occluding part passes through the detection position 501 to the total time the occluding part passes through the detection position 501.

[0123] Referring to Figure 13, in some embodiments, when the first blocking part 231 includes a first gap 2313 and the second blocking part 241 includes a second gap 2413, the length of the first gap 2313 is greater than or less than the length of the second gap 2413 (in the figure, the length of the first gap 2313 is less than the length of the second gap 2413 is taken as an example), that is, the lengths of the first gap 2313 and the second gap 2413 are not equal; in this way, the triggering situations generated when the first gap 2313 and the second gap 2413 pass through the detection bit 501 are different. For example, referring to Figures 13 and 14, the detection position 501 includes a detection groove. Two photoelectric sensors are arranged at intervals along the depth direction on the inner wall of the detection groove. The transmitting and receiving parts of the photoelectric sensors are respectively located on the inner walls of the two sides of the detection groove. The length of the first gap 2313 is less than the length of the second gap 2413. When the first gap 2313 passes through the detection groove, the photoelectric sensor near the bottom of the detection groove is opposite to the first gap 2313 and is not blocked, while the photoelectric sensor near the opening of the detection groove is blocked by the first blocking part 231. When the second gap 2413 passes through the detection groove, since the length of the second gap 2413 is longer, both photoelectric sensors can be opposite to the second gap 2413 and are not blocked. Thus, when the first gap 2313 passes through the detection groove and the second gap 2413 passes through the detection groove, the electrical signals generated by the detection component 50 will be significantly different, and it is possible to clearly distinguish whether the first blocking part 231 or the second blocking part 241 passes through the detection groove.

[0124] Based on the solutions of any of the three embodiments described above, this embodiment can further adopt a configuration where the first blocking part 231 and the second blocking part 241 are located on the same circumference. That is, the first blocking part 231 and the second blocking part 241 are arranged at intervals along the rotation direction of the paddle assembly 20. The detection position 501 includes a detection groove located in the interval area between the first blocking part 231 and the second blocking part 241. Thus, when the paddle assembly 20 rotates in the first direction, the first blocking part 231 rotates towards the detection groove to pass through the detection groove; when the paddle assembly 20 rotates in the second direction, the second blocking part 241 rotates towards the detection groove to pass through the detection groove. The detection assembly 50 uses the solutions in the three embodiments described above to identify and distinguish whether the first blocking part 231 or the second blocking part 241 passes through the detection groove, thereby accurately determining the rotation direction of the paddle assembly 20.

[0125] Referring to Figures 3 and 8, in some embodiments, the first detection unit 23 further includes a third blocking part 232, with a third gap 25 between the third blocking part 232 and the first blocking part 231; the second detection unit 24 further includes a fourth blocking part 242, with a fourth gap 26 between the fourth blocking part 242 and the second blocking part 241; the third gap 25 is located between the third blocking part 232 and the first sub-blocking part 2311, and the fourth gap 26 is located between the fourth blocking part 242 and the third sub-blocking part 2411. The third gap 25 and the fourth gap 26 correspond in the length direction of the paddle assembly 20. When the paddle assembly 20 is in the initial position, the third gap 25 and the fourth gap 26 are set at the detection position 501; that is, when the paddle assembly 20 is in the initial position, the detection position 501 will not detect either the first detection unit 23 or the second detection unit 24. When the paddle assembly 20 rotates in the first direction, the first blocking part 231 and the fourth blocking part 242 rotate toward the detection position 501 to enter the detection position 501; when the paddle assembly 20 rotates in the second direction, the second blocking part 241 and the third blocking part 232 rotate toward the detection position 501 to enter the detection position 501.

[0126] When the detection position 501 includes a first detection groove 5011 and a second detection groove 5012 arranged along the length of the paddle assembly 20, and the first detection part 23 and the second detection part 24 are arranged at intervals corresponding to the first detection groove 5011 and the second detection groove 5012 respectively, with the first detection groove 5011 used to detect the first detection part 23 and the second detection groove 5012 used to detect the second detection part 24, when the paddle assembly 20 rotates in the first direction, the first blocking part 231 passes through the first detection groove 5011, and at the same time the fourth blocking part... 242 passes through the second detection slot 5012. The detection component 50 can determine whether the paddle assembly 20 is being paddled in the first direction based on the detection signals from the first detection slot 5011 and the second detection slot 5012. When the paddle assembly 20 rotates in the second direction, the second blocking part 241 passes through the second detection slot 5012, and at the same time, the third blocking part 232 passes through the first detection slot 5011. The detection component 50 can then determine whether the paddle assembly 20 is being paddled in the second direction based on the detection signals from the first detection slot 5011 and the second detection slot 5012.

[0127] Furthermore, when the first blocking part 231 includes a first sub-blocking part 2311, a second sub-blocking part 2312, and a first gap 2313, and the second blocking part 241 includes a third sub-blocking part 2411, a fourth sub-blocking part 2412, and a second gap 2413, the first blocking part 231 will generate two interval blocking signals sequentially when passing through the first detection groove 5011, the second blocking part 241 will also generate two interval blocking signals sequentially when passing through the first detection groove 5011, the third blocking part 232 will generate a continuous blocking signal when passing through the first detection groove 5011, and the fourth blocking part 242 will also generate a continuous blocking signal when passing through the second detection groove 5012. Therefore, the detection component 50 can determine which blocking part passes through the first detection groove 5011 and the second detection groove 5012 based on the signal situation generated by the first detection groove 5011 and the second detection groove 5012, and thus accurately determine the toggle direction of the paddle assembly 20. Furthermore, the detection component 50 can calculate the actuation speed of the paddle assembly 20 based on the time interval between the two detected obstruction signals and the size of the corresponding sub-obstruction part. In this way, accurate detection of the actuation direction and speed of the paddle assembly 20 of the paddle device can be achieved.

[0128] Referring to FIG15, in some embodiments, the plectrum device further includes a rotation speed detection device 60, which is used to detect the rotation speed of the plectrum assembly 20. The rotation speed detection device 60 is electrically connected to the main control circuit 70 of the instrument, and the main control circuit 70 is used to control the output volume of the instrument according to the electrical signal emitted by the rotation speed detection device 60.

[0129] In this embodiment, the rotation speed detection device 60 can be a device that calculates the rotation speed of the plectrum assembly 20 based on the signals fed back by the detection component 50 (such as the detection signals fed back by the first detection slot 5011 and the second detection slot 5012). The rotation speed detection device 60 can also be a detection device that independently detects the rotation speed of the plectrum assembly, such as various types of rotation speed sensors. When the plectrum assembly is installed on a musical instrument, the rotation speed detection device 60 is electrically connected to the main control circuit 70 of the instrument. When the main control circuit 70 receives the electrical signal sent by the rotation speed detection device 60, it controls the output volume of the instrument according to the electrical signal. In some embodiments, the rotation speed of the plectrum assembly 20 detected by the rotation speed detection device 60 can include direction; for example, the rotation speed in the first direction is represented by a positive rotation speed, and the rotation speed in the second direction is represented by a negative rotation speed. Thus, the main control circuit 70 can also control the output volume and rhythm of the instrument according to the electrical signal sent by the rotation speed detection device 60.

[0130] Referring to Figure 15, in some embodiments, the rotational speed detection device 60 includes a timer 61 and a control circuit 62; the first detection unit 23 has a first measured position 233 and a second measured position 234. When the paddle assembly 20 rotates along the first direction, the timer 61 is used to record the time from when the first measured position 233 passes the detection position 501 to when the second measured position 234 passes the detection position 501; wherein, when the first measured position 233 and the second measured position 234 pass the detection position 501, they will generate corresponding special signals that can be identified by the detection assembly 50. Thus, the control circuit 62 can determine the time when the first measured position 233 and the second measured position 234 pass the detection position 501 based on the signals identified and fed back by the detection assembly 50, and then control the timer 61 to accurately start timing, so as to obtain the time from when the first measured position 233 passes the detection position 501 to when the second measured position 234 passes the detection position 501, that is, the interval between when the first measured position 233 and the second measured position 234 arrive at the detection position 501 one after the other. The distance between the first measured position 233 and the second measured position 234 on the first detection unit 23 is fixed. After the control circuit 62 obtains the time interval between the arrival of the first measured position 233 and the second measured position 234 at the detection position 501 through the timer 61, the control circuit 62 calculates the rotation speed of the paddle assembly 20 based on the distance between the first measured position 233 and the second measured position 234 and the time recorded by the timer 61. That is, the rotation speed of the paddle assembly 20 is obtained by dividing the distance by the time.

[0131] Referring to Figures 3 and 8, further, in some embodiments, when the first blocking portion 231 includes a first sub-blocking portion 2311, a second sub-blocking portion 2312, and a first gap 2313, with the first gap 2313 located between the first sub-blocking portion 2311 and the second sub-blocking portion 2312; when the paddle assembly 20 rotates along the first direction, the first sub-blocking portion 2311, the first gap 2313, and the second sub-blocking portion 2312 successively enter the detection position 501; in this embodiment, the side of the first sub-blocking portion 2311 away from the first gap 2313 is taken as the first measured position 233, and the side of the second sub-blocking portion 2312 adjacent to the first gap 2313 is taken as the second measured position 234. Thus, when the first measured bit 233 passes the detection bit 501, that is, when the first sub-blocking part 2311 just enters the detection bit 501, the first blocking signal is generated. When the detection component 50 determines that the first blocking signal has been generated, the control circuit 62 controls the timer 61 to start timing. When the first sub-blocking part 2311 passes the detection bit 501, the first gap 2313 then passes the detection bit 501, and there is no blocking signal at this time. After the first gap 2313 passes the detection bit 501, the second sub-blocking part 2312 just enters the detection bit 501, and the second blocking signal is generated. When the detection component 50 determines that the second blocking signal has been generated, the control circuit 62 controls the timer 61 to stop timing. In this way, the time from when the first measured bit 233 passes the detection bit 501 to when the second measured bit 234 passes the detection bit 501 is obtained.

[0132] In some embodiments, the second detection unit 24 has a third measured position 243 and a fourth measured position 244. When the toggle assembly 20 rotates along the second direction, the timer 61 is used to record the time from when the third measured position 243 passes the detection position 501 to when the fourth measured position 244 passes the detection position 501. When the third measured position 243 and the fourth measured position 244 pass the detection position 501, they will generate corresponding special signals that can be identified by the detection assembly 50. Thus, the control circuit 62 can determine the time when the third measured position 243 and the fourth measured position 244 pass the detection position 501 based on the signals identified and fed back by the detection assembly 50, and then control the timer 61 to accurately start the timing so as to obtain the time from when the third measured position 243 passes the detection position 501 to when the fourth measured position 244 passes the detection position 501, that is, the interval between when the third measured position 243 and the fourth measured position 244 arrive at the detection position 501 one after the other. The distance between the third measured position 243 and the fourth measured position 244 on the second detection unit 24 is fixed. After the control circuit 62 obtains the interval between the arrival of the third measured position 243 and the fourth measured position 244 at the detection position 501 through the timer 61, the control circuit 62 calculates the rotation speed of the paddle assembly 20 based on the distance between the third measured position 243 and the fourth measured position 244 and the time recorded by the timer 61. That is, the rotation speed of the paddle assembly 20 is obtained by dividing the distance by the time.

[0133] Referring to Figures 3 and 8, further, in some embodiments, when the second blocking portion 241 includes a third sub-blocking portion 2411, a fourth sub-blocking portion 2412, and a second gap 2413, with the second gap 2413 located between the third sub-blocking portion 2411 and the fourth sub-blocking portion 2412; when the paddle assembly 20 rotates along the second direction, the third sub-blocking portion 2411, the second gap 2413, and the fourth sub-blocking portion 2412 successively enter the detection position 501; in this embodiment, the side of the third sub-blocking portion 2411 away from the second gap 2413 is taken as the third measured position 243, and the side of the fourth sub-blocking portion 2412 adjacent to the second gap 2413 is taken as the fourth measured position 244. Thus, when the third measured position 243 passes the detection position 501, that is, when the third sub-blocking part 2411 just enters the detection position 501, the first blocking signal is generated. When the detection component 50 determines that the first blocking signal has been generated, the control circuit 62 controls the timer 61 to start timing. When the third sub-blocking part 2411 passes the detection position 501, the second gap 2413 then passes the detection position 501. At this time, there is no blocking signal. After the second gap 2413 passes the detection position 501, the fourth sub-blocking part 2412 just enters the detection position 501, and the second blocking signal is generated. When the detection component 50 determines that the second blocking signal has been generated, the control circuit 62 controls the timer 61 to stop timing. In this way, the time from when the third measured position 243 passes the detection position 501 to when the fourth measured position 244 passes the detection position 501 is obtained.

[0134] Of course, in other embodiments, the first measured position 233 and the second measured position 234 can also be other positions of the first blocking portion 231; for example, the first measured position 233 is the side of the first sub-blocking portion 2311 away from the first gap 2313, and the second measured position 234 is the side of the first sub-blocking portion 2311 adjacent to the first gap 2313. In other embodiments, the third measured position 243 and the fourth measured position 244 can also be other positions of the second blocking portion 241; for example, the third measured position 243 is the side of the third sub-blocking portion 2411 away from the second gap 2413.

[0135] Referring to Figures 1 and 2, in some embodiments, the number of first rotation positions 101, second rotation positions 102, paddle components 20, and detection components 50 are all two. The two first rotation positions 101 are located in the middle of the support assembly 10, and the two second rotation positions 102 are located at both ends of the support assembly 10. When the support assembly 10 includes a paddle bracket 11 and a rotating shaft bracket 12, the rotating shaft bracket 12 is located in the middle of the paddle bracket 11, the two first rotation positions 101 are located at both ends of the rotating shaft bracket 12, and the two second rotation positions 102 are located at both ends of the paddle bracket 11. The two paddle components 20 are rotatably connected to the two first rotation positions 101 and the two second rotation positions 102, respectively. That is, one paddle component 20 is rotatably connected between one first rotation position 101 and one second rotation position 102, and the other paddle component 20 is rotatably connected between another first rotation position 101 and another second rotation position 102. The two paddle components 20 are arranged sequentially along the length of the support assembly 10. Two detection components 50 are used to detect the two pick components 20 respectively. Thus, when any pick component 20 is plucked, the corresponding detection component 50 detects the plucking of the pick component 20 and sends the corresponding electrical signal to the instrument controller, which then controls the instrument to produce the corresponding sound.

[0136] Of course, in some other embodiments, the number of the first rotation position 101, the second rotation position 102, the paddle assembly 20 and the detection assembly 50 may be only one, that is, the paddle device has only one paddle assembly 20; or the number of the first rotation position 101, the second rotation position 102, the paddle assembly 20 and the detection assembly 50 may be three or more, that is, the paddle device has three or more paddle assemblies 20, and each detection assembly 50 detects its corresponding paddle assembly 20.
