Description

Technical Field

[0001] This utility model relates to the field of percussion instruments, and in particular to an auxiliary device for testing the force of percussion instruments. Background Technology

[0002] In the percussion instrument category of electronic drums, the sound production principle of electronic drums is as follows: an electronic drum set has multiple triggers, and each trigger has a built-in vibration sensor. When the vibration sensor receives the striking signal applied by the drummer, the vibration sensor transmits the corresponding vibration signal to the sound source, which processes it and outputs the corresponding volume and timbre.

[0003] In electronic drum kits, a crucial indicator of a trigger's quality is its percussion response—its sensitivity (meaning the trigger should respond promptly and without leaks when struck at varying pressures (low, medium, and high). Currently, there's no standardized testing method for sensitivity in the electronic drum industry; it's often determined subjectively by the drummer. This subjective judgment leads to inconsistent results. Different drummers may yield different assessments of the same drum set due to variations in striking habits and techniques, or even the same drummer may arrive at different conclusions when testing the same drum set at different times. Therefore, the lack of a standardized force measurement device presents significant challenges to design and development. Utility Model Content

[0004] To overcome the above problems, this utility model provides an auxiliary device for testing the force of percussion instruments. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0005] An auxiliary device for testing the force of a percussion instrument includes a base, on which a fixing mechanism and a lifting mechanism are provided. The lifting mechanism is provided with a scale plate and a fixed arm. The scale plate is provided with an arc-shaped through groove, and the side of the arc-shaped through groove is provided with a scale. A swing arm is hinged to the fixed arm. The other end of the swing arm is provided with a support structure and a sliding member. The sliding member passes through the arc-shaped through groove, and the swing arm slides along the arc-shaped through groove through the sliding member. A locking member is provided on the sliding member to lock the swing arm in the arc-shaped through groove. A cycloid is also provided on the fixed arm. The other end of the cycloid is connected to a pendulum, and the pendulum is placed in the support structure. The fixing mechanism fixes the instrument, and the instrument is located on the downward swing path of the pendulum. When the support structure is opened, the pendulum swings downward to strike the instrument.

[0006] Furthermore, the lifting mechanism includes a linear slide module, which includes a lead screw and a slider. One end of the lead screw is connected to a rocker handwheel. The scale plate and the fixed arm are both mounted on the slider. By shaking the rocker handwheel, the lead screw rotates and drives the slider to move up and down to adjust the height of the scale plate and the fixed arm.

[0007] Furthermore, the sliding component is a double-ended connecting rod, one end of which is fixedly connected to the swing arm, and the other end of which is inserted into an arc-shaped through groove. The locking component is a nut, which is threadedly connected to the other end of the double-ended connecting rod to tighten and fix the swing arm.

[0008] Furthermore, the supporting structure includes a bracket and a torsion spring. The bracket is hinged to the swing arm via a connecting rod, and the torsion spring is sleeved on the connecting rod. The torsion spring has a tendency to drive the bracket to retract. The pendulum ball is placed inside the bracket, and a lever is provided on the bracket. By moving the lever, the bracket opens to release the pendulum ball.

[0009] Furthermore, the fixed arm is provided with a fastening hole, and a fastening screw is provided in the fastening hole. One end of the cycloidal line is fixed in the fastening hole by the fastening screw.

[0010] Furthermore, the pendulum string and pendulum bob are detachably and fixedly connected to each other for easy replacement of the pendulum bob.

[0011] Furthermore, a screw is connected to one end of the cycloidal line, and a screw hole is provided on the cycloidal ball. The cycloidal line is passed through the screw hole to achieve a detachable fixed connection with the cycloidal ball.

[0012] The beneficial effects of this utility model are as follows:

[0013] The device includes a base with a fixing mechanism and a lifting mechanism. The lifting mechanism has a scale plate and a fixed arm. The scale plate has an arc-shaped groove with graduations on its side. A swing arm is hinged to the fixed arm, and the other end of the swing arm has a support structure and a sliding member. The sliding member passes through the arc-shaped groove, and the swing arm slides along the groove via the sliding member. A locking member is provided on the sliding member to lock the swing arm in the arc-shaped groove. A cycloid is also provided on the fixed arm, with the other end of the cycloid connected to a pendulum ball, which is placed inside the support structure. The fixing mechanism holds the musical instrument, which is located on the downward swing path of the pendulum ball. When the support structure is opened, the pendulum ball swings downward to strike the instrument. This allows for a fixed force to be applied to each strike, and the force of each strike can be adjusted according to the scale, facilitating the acquisition of vibration signals generated by the instrument under test at that force using an external signal acquisition device.

Detailed Implementation

[0021] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "A Percussion Instrument Force Testing Auxiliary Device" is provided in conjunction with the accompanying drawings.

[0022] See Figures 1-3 In this embodiment, the testing auxiliary device includes a base 100, on which a fixing mechanism 101 and a lifting mechanism 102 are provided. The lifting mechanism 102 is provided with a scale plate 103 and a fixed arm 104. The scale plate 103 has an arc-shaped through groove 105, and the side of the arc-shaped through groove 105 has graduations. A swing arm 106 is hinged to the fixed arm 104. The other end of the swing arm 106 is provided with a supporting structure 107 and a sliding member 108. The sliding member 108 passes through the arc-shaped through groove 105, and the swing arm 106 moves along the arc-shaped through groove 105. The arc-shaped through groove 105 swings, and the sliding member 108 is provided with a locking member 109 to lock the swing arm 106 on the arc-shaped through groove 105; the fixed arm 104 is also provided with a pendulum 110, the other end of which is connected to the pendulum ball 111, which is placed in the support structure 107; the fixing mechanism 101 fixes the instrument under test, and the test point of the instrument under test is located in the vertical direction of the pendulum ball 111 during its downward swing (that is, the position where the pendulum ball has the greatest kinetic energy at this time). When the support structure 107 is opened, the pendulum ball 111 swings downward to strike the instrument under test.

[0023] When using, please refer to Figure 2The instrument under test is fixed by the fixing mechanism 101, and the external signal acquisition device (not shown) is set up. The scale plate 103 and the fixing arm 104 are raised and lowered to a suitable position by the lifting mechanism 102. After the pendulum ball 111 is set up, the length of the pendulum line 110 is adjusted so that the pendulum ball 111 is placed in the support structure 107 and the pendulum line 110 is just taut. Then, the swing arm 106 is adjusted to swing upward along the arc through groove 105 to the scale value to be tested, and the support structure 107 and the pendulum ball 111 are driven to the corresponding scale. The swing arm 106 is fixed by the locking part 109, the support structure 107 is opened, and the pendulum ball 111 swings downward under the action of gravity, striking the instrument under test. The instrument under test has a built-in vibration sensor, and the external "signal acquisition device" picks up the vibration signal of the instrument under test and converts it into a recognizable electrical signal and waveform. The swing arm 106 was then adjusted to different heights on the scale (i.e., the swing arm was placed at different heights, corresponding to different gravitational potential energies of the pendulum), and the above test was repeated to simulate the effect of a drummer striking the instrument with light, medium, and heavy force. This auxiliary device ensures the consistency of striking force at corresponding scales, facilitating the testing of instrument sensitivity. It avoids the subjective judgment of the drummer, providing a complete testing standard and auxiliary equipment for the design and development of percussion instruments, effectively ensuring the stability and consistency of the product.

[0024] See further Figure 3 In this embodiment, the lifting mechanism 102 includes a linear slide module, which includes a lead screw 1021 and a slider 1022. One end of the lead screw 1021 is connected to a rocker handwheel 1023. The scale plate 103 and the fixed arm 104 are both mounted on the slider 1022. By rocking the rocker handwheel 1023, the lead screw 1021 rotates, causing the slider 1022 to move up and down, thereby adjusting the height of the scale plate 103 and the fixed arm 104. This allows for sensitivity testing of musical instruments of different sizes, expanding the application range.

[0025] See further Figure 4 In this embodiment, the sliding member 108 is a double-ended connecting rod. One end of the double-ended connecting rod is fixedly connected to the swing arm 106, and the other end of the double-ended connecting rod passes through the arc groove 105. The locking member 109 is a nut, which is threadedly connected to the other end of the double-ended connecting rod to tighten and fix the swing arm 106.

[0026] More specifically, in this embodiment, the supporting structure 107 includes a bracket 1071 and a torsion spring 1072. The bracket 1071 is hinged to the swing arm 106 via a connecting rod 1073. The torsion spring 1072 is sleeved on the connecting rod 1073 and has a tendency to drive the bracket 1071 to retract. The pendulum ball 111 is placed inside the bracket 1071. A lever 1074 is provided on the bracket 1071. By moving the lever 1074, the torsion spring 1072 can be compressed to open the bracket 1071 and release the pendulum ball 111. When the lever 1074 is released, the torsion spring 1072 drives the bracket 1071 to retract, making it convenient to support the pendulum ball 111 next time.

[0027] Furthermore, in this embodiment, a fastening hole is provided on the fixed arm 104, and a fastening screw is provided in the fastening hole. One end of the cycloidal line 110 is fixed in the fastening hole by the fastening screw, and the length of the cycloidal line 110 can be adjusted by loosening the fastening screw.

[0028] More specifically, in this embodiment, the cycloidal line 110 and the pendulum ball 111 are detachably fixedly connected so as to replace different pendulum balls 111; preferably, one end of the cycloidal line 110 is coaxially connected with a screw, the pendulum ball 111 is provided with a screw hole, and the cycloidal line 110 is threadedly connected to the screw hole by a screw, so as to realize the detachable fixed connection between the cycloidal line 110 and the pendulum ball 111.
