Description

Technical Field

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

[0002] An electronic hi-hat is an instrument played by moving the hi-hat up and down on a sound generator using a pedal and lever. The system obtains the distance the hi-hat moves and calculates its speed, transmitting this information to a data processing module. This module processes the received electrical signals to generate an audio signal output. However, current methods for measuring hi-hat movement distance typically use a single measurement structure, and the results are heavily influenced by this structure, making it difficult to consistently and effectively obtain accurate distance readings. Therefore, accurately measuring the hi-hat's movement distance is crucial for accurate audio output. Utility Model Content

[0003] The purpose of this invention is to provide a trigger to solve the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides a trigger, including a substrate, a first ranging component, a second ranging component, and a main controller. A device under test (DUT) is slidably disposed on one side of the substrate's working end face, and the movement path of the DUT is perpendicular to the working end face. The first ranging component is disposed between the working end face and the DUT, and includes a ranging sensor and a ranging detection position. One of the ranging sensor and the ranging detection position is disposed on the working end face, and the other is correspondingly disposed on the DUT. The second ranging component is disposed between the working end face and the DUT, and includes a thin-film internal resistance switch and a contact component. One of the thin-film internal resistance switch and the contact component is disposed on the working end face, and the other is correspondingly disposed on the DUT. The contact component is slidably connected to the working surface of the thin-film internal resistance switch.

[0005] The ranging sensor, the thin-film internal resistance switch, and the contact component are all signal-connected to the main controller. The main controller obtains the first movement distance of the device under test based on the signal transmitted from the ranging sensor. The main controller obtains the second movement distance of the device under test based on the signals transmitted from the thin-film internal resistance switch and the contact component. The main controller outputs the movement distance of the device under test based on the first movement distance and the second movement distance.

[0006] Optionally, a limiting rod is detachably connected to one side of the working end face of the substrate, and the limiting rod is arranged perpendicularly to the substrate; the test piece is a sliding sleeve, and the sliding sleeve is slidably disposed outside the limiting rod.

[0007] Optionally, a measuring plate is detachably connected to the radially outer side of the sliding sleeve, the measuring plate and the base plate are arranged in parallel, the distance sensor and the distance detection position are respectively disposed on the measuring plate and the base plate, the contact component is rotatably disposed on the measuring plate, and the thin film internal resistance switch is detachably connected to the base plate.

[0008] Optionally, a fixing plate is detachably connected to the base plate at the position corresponding to the measuring plate, and the distance sensor is detachably connected to the side of the fixing plate close to the measuring plate. The position opposite to the measuring plate and the distance sensor is the distance detection position.

[0009] Optionally, the ranging sensor is any one of a photoelectric displacement sensor, an ultrasonic displacement sensor, and a laser displacement sensor.

[0010] Optionally, the contact component is a disc, and a rotating shaft is detachably connected to the central axis of the disc. The rotating shaft is rotatably connected to the measuring plate. The rotation axis of the disc is parallel to the substrate. The thin-film internal resistance switch is arranged parallel to the limiting rod.

[0011] Optionally, it also includes a mounting flange, which has a limiting hole, through which the test piece is arranged, and the mounting flange is detachably connected to the base plate.

[0012] Optionally, a housing is detachably connected between the mounting flange and the base plate, and the ranging sensor, the ranging detection position, the thin-film internal resistance switch and the contact component are all disposed inside the housing.

[0013] Compared with the prior art, the present invention has the following advantages and technical effects:

[0014] Before operation, the test piece is connected to the pedal or lever of the hi-hat. When the hi-hat is stepped on or struck, the pedal or lever moves the test piece. Since the test piece is slidably mounted on one side of the working end face of the substrate, its movement path is perpendicular to the working end face. As the test piece moves, the distance between it and the working end face of the substrate changes. This invention uses a first ranging component and a second ranging component to detect the distance between the test piece and the working end face of the substrate in real time. In the first ranging component, one of the ranging sensor and the ranging detection position is located on the working end face, and the other is correspondingly located on the test piece. The distance is detected by the ranging sensor... The distance between the distance measuring sensor and the distance measuring detection position is detected in real time to obtain the "first moving distance" of the hi-hat. In the second distance measuring component, one of the thin-film internal resistance switch and the contact component is set on the working end face, and the other is set on the test piece. When the test piece moves, it drives one of the contact component and the thin-film internal resistance switch to move, thereby changing the contact position of the thin-film internal resistance switch and the contact component, thereby changing the effective resistance of the thin-film internal resistance switch (refer to the sliding rheostat), thereby obtaining the moving distance of either the moving contact component or the thin-film internal resistance switch, and thus obtaining the "second moving distance" of the hi-hat. This embodiment simultaneously includes a first ranging component and a second ranging component. Both components operate concurrently, obtaining a first movement distance and a second movement distance, respectively. The main controller calculates the difference between the data from the first and second movement distances and determines whether the difference is within the error range. If within the range, it calculates and outputs the movement distance of the device under test. If the difference is outside the error range, it outputs a warning signal. The operator continuously steps on or strikes the cymbal based on the warning signal. The main controller continuously obtains the first and second movement distances and continuously determines whether the difference is within the error range, thus determining whether the first and second ranging components are damaged. This invention uses the first and second ranging components to detect the distance between the device under test and the working end face of the substrate in real time. The two sets of data mutually verify each other, enabling a more accurate determination of the cymbal's movement distance. Attached Figure Description

Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this utility model can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Referring to the accompanying drawings, this utility model provides a trigger, including a substrate 1, a first ranging component, a second ranging component, and a main controller. A test piece 2 is slidably disposed on one side of the working end face of the substrate 1, and the movement path of the test piece 2 is perpendicular to the working end face. The first ranging component is disposed between the working end face and the test piece 2, and includes a ranging sensor 3 and a ranging detection position 4. One of the ranging sensor 3 and the ranging detection position 4 is disposed on the working end face, and the other is correspondingly disposed on the test piece 2. The second ranging component is disposed between the working end face and the test piece 2, and includes a thin-film internal resistance switch 5 and a contact component. One of the thin-film internal resistance switch 5 and the contact component is disposed on the working end face, and the other is correspondingly disposed on the test piece 2. The contact component is slidably connected to the working surface of the thin-film internal resistance switch 5.

[0023] In this embodiment, when the ranging sensor 3 is disposed on the working end face of the substrate 1, the ranging detection position 4 is disposed on the device under test 2; when the ranging detection position 4 is disposed on the working end face of the substrate 1, the ranging sensor 3 is disposed on the device under test 2; in both cases, the ranging sensor 3 and the ranging detection position 4 are arranged accordingly. When the thin-film internal resistance switch 5 is disposed on the working end face, the contact component is connected to the device under test 2; when the thin-film internal resistance switch 5 is connected to the device under test 2, the contact component is disposed on the working end face; in both cases, the contact component is slidably connected to the working surface of the thin-film internal resistance switch 5.

[0024] The ranging sensor 3, the thin-film internal resistance switch 5, and the contact component are all connected to the main controller. The main controller obtains the first movement distance of the device under test 2 based on the signal transmitted from the ranging sensor 3. The main controller obtains the second movement distance of the device under test 2 based on the signals transmitted from the thin-film internal resistance switch 5 and the contact component. The main controller outputs the movement distance of the device under test 2 based on the first movement distance and the second movement distance.

[0025] Before operation, the test piece 2 is connected to the pedal or lever of the hi-hat. When the hi-hat is stepped on or struck, the pedal or lever moves the test piece 2. Since the test piece 2 is slidably disposed on one side of the working end face of the substrate 1, the movement path of the test piece 2 is perpendicular to the working end face. When the test piece 2 moves, the distance between the test piece 2 and the working end face of the substrate 1 changes. In this embodiment, the distance between the test piece 2 and the working end face of the substrate 1 is detected in real time by a first ranging component and a second ranging component. In the first ranging component, one of the ranging sensor 3 and the ranging detection position 4 is disposed on the working end face, and the other is disposed on the test piece 2. The distance is detected by the ranging sensor 3 and the ranging detection position 4. Sensor 3 detects the distance between the distance measuring sensor 3 and the distance measuring detection position 4 in real time, thereby obtaining the moving distance of the hi-hat, "first moving distance"; in the second distance measuring assembly, one of the thin-film internal resistance switch 5 and the contact component is set on the working end face, and the other is correspondingly set on the test piece 2. When the test piece 2 moves, it drives one of the contact component and the thin-film internal resistance switch 5 to move, thereby changing the contact position of the thin-film internal resistance switch 5 and the contact component, thereby changing the effective resistance of the thin-film internal resistance switch 5 (refer to the sliding rheostat), thereby obtaining the moving distance of the moving contact component or the thin-film internal resistance switch 5, and thus obtaining the moving distance of the hi-hat, "second moving distance". This embodiment simultaneously includes a first ranging component and a second ranging component. The two ranging components work together to obtain a first movement distance and a second movement distance, respectively. The main controller calculates the difference between the data of the first movement distance and the second movement distance and determines whether the difference is within the error range. If it is within the range, it calculates and outputs the movement distance of the device under test 2. If the difference is not within the error range, it outputs a warning signal. The operator continuously steps on or strikes the cymbal according to the warning signal. The main controller continuously obtains the first movement distance and the second movement distance calculation and continuously determines whether the difference is within the error range to determine whether the first ranging component and the second ranging component are damaged. This utility model uses the first ranging component and the second ranging component to detect the distance between the device under test 2 and the working end face of the base plate 1 in real time. The two sets of data are mutually verified, which can more accurately obtain the movement distance of the cymbal.

[0026] In this embodiment, the substrate 1 can be configured with different shapes or arranged in different positions as needed, but it is necessary to ensure that the movement path of the test piece 2 is perpendicular to the working end face of the substrate 1. When the test piece 2 moves, the first and second ranging components can detect the distance between the test piece 2 and the working end face of the substrate 1 in real time. Preferably, a limiting rod 6 is detachably connected to one side of the working end face of the substrate 1, and the limiting rod 6 is arranged perpendicularly to the substrate 1; the test piece 2 is a sliding sleeve, which is slidably disposed outside the limiting rod 6; in this embodiment, the test piece 2 and the substrate 1 are arranged perpendicularly, and the test piece 2 is limited to sliding only along the limiting rod 6. At this time, the working end face is the end face of the substrate near the sliding sleeve. During operation, the pedal or pull rod drives the limiting rod 6 of the test piece 2 to slide, and the distance between the test piece 2 and the substrate 1 changes.

[0027] Preferably, a measuring plate 7 is detachably connected to the radially outer side of the sliding sleeve. The measuring plate 7 and the base plate 1 are arranged in parallel. The distance sensor 3 and the distance detection position 4 are respectively disposed on the measuring plate 7 and the base plate 1. The contact component is rotatably disposed on the measuring plate 7. The thin-film internal resistance switch 5 is detachably connected to the base plate 1. In this embodiment, since the limiting rod 6 and the base plate 1 are arranged vertically, and the sliding sleeve is slidably disposed on the outer side of the limiting rod 6, that is, the sliding sleeve and the base plate 1 are arranged vertically, and since the measuring plate 7 is detachably connected to the radially outer side of the sliding sleeve, and the measuring plate 7 and the base plate 1 are arranged in parallel, when the test piece 2 moves, the change in distance between the test piece 2 and the base plate 1 is equal to the change in distance between the measuring plate 7 and the base plate 1. In this embodiment, the distance sensor 3 and the distance detection position 4 are respectively disposed on the measuring plate 7 and the base plate 1, the contact component is rotatably disposed on the measuring plate 7, and the thin-film internal resistance switch 5 is detachably connected to the base plate 1. The first distance measuring component and the second distance measuring component can directly detect the position change of the measuring plate 7 in real time, so as to accurately obtain the moving distance of the cymbal.

[0028] In a further optimized design, a fixing plate 8 is detachably connected to the base plate 1 at the position corresponding to the measuring plate 7. A distance sensor 3 is detachably connected to the side of the fixing plate 8 near the measuring plate 7. The position opposite the measuring plate 7 and the distance sensor 3 is the distance detection position 4. In this embodiment, the fixing plate 8 is detachably connected to the base plate 1 at the position corresponding to the measuring plate 7, and the distance sensor 3 is detachably connected to the side of the fixing plate 8 near the measuring plate 7. The distance between the distance sensor 3 and the distance detection position 4 is detected in real time by the distance sensor 3, and the change in position of the measuring plate 7 is calculated; thus, the movement distance of the cymbal can be accurately obtained.

[0029] In this embodiment, the ranging sensor 3 is any one of a photoelectric displacement sensor, an ultrasonic displacement sensor, and a laser displacement sensor. All of these displacement sensors can quickly and in real time detect the distance change between the working end face and the workpiece 2 under test.

[0030] Further optimization of the design: the contact component is a disc 9, with a detachable rotating shaft 10 connected to the central axis of the disc 9. The rotating shaft 10 is rotatably connected to the measuring plate 7. The rotation axis of the disc 9 is parallel to the base plate 1. The thin-film internal resistance switch 5 is arranged parallel to the limiting rod 6. The disc 9 is rotatably connected to the measuring plate 7 via the rotating shaft 10, meaning the disc 9 can rotate around the central axis of the rotating shaft 10. Since the contact component slides against the working surface of the thin-film internal resistance switch 5, when the test piece 2 slides along the limiting rod 6, the measuring plate 7 slides synchronously along the limiting rod 6. Due to the contact between the disc 9 and the thin-film internal resistance switch 5, the disc 9 begins to rotate under the action of friction, thereby changing the position of the contact point between the disc 9 and the thin-film internal resistance switch 5. The actual resistance of the thin-film internal resistance switch 5 changes, allowing the calculation of the movement of the disc 9 and the measuring plate 7, thus accurately obtaining the movement distance of the cymbal.

[0031] In some embodiments, the trigger further includes a mounting flange 11 with a limiting hole 12. The test piece 2 passes through the limiting hole 12 and is detachably connected to the base plate 1. In this embodiment, the mounting flange 11 is detachably connected to the base plate 1 and also connected to the main structure of the hi-hat, thus fixing the position of the trigger. The limiting hole 12 of the mounting flange 11 can also restrict the radial movement of the test piece 2. In a further optimized design, a housing 13 is detachably connected between the mounting flange 11 and the base plate 1. The ranging sensor 3, the ranging detection position 4, the thin-film internal resistance switch 5, and the contact components are all disposed inside the housing 13. The housing 13 separates the internal structure from the other structures of the hi-hat, thus protecting the internal structure.
