Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes.

Example one

As shown in fig. 1 to 6, the present invention provides an electronic percussion instrument with height-adjustable sensor, such as an electronic drum, comprising a drum head 1, a drum head sensing part 4, a supporting plate 6 and a main body part 8; the drumhead 1 is positioned on the main body part 8 and fixed with the main body part 8, and the drumhead 1 is a surface which is struck by a striking object such as a stick; the drumhead sensing part 4 and the supporting plate 6 are both positioned in a cavity formed by the main body part 8 and the drumhead 1, the drumhead sensing part 4 is positioned on the supporting plate 6, and the supporting plate 6 is fixed with the main body part 8; the drumhead sensing part 4 comprises a buffer 41, a sensor 42, a top cover 44 and a base 45 from top to bottom, the drumhead 1 presses on the buffer 41 to enable the buffer 41 to have a pre-compression amount, the buffer 41 comprises an elastic material, and the compression amount of the buffer 41 is changed when the drumhead 1 is struck; the circumferential surface of the base 45 is provided with a second thread 45a, the circumferential surface of the top cover 44 is provided with a first thread 44b matched with the second thread 45a, so that the base 45 and the top cover 44 are connected in a thread fit mode, namely the top cover 44 is sleeved on the base 45, the height of the sensor 42 can be adjusted by rotating the base 45 and/or the top cover 44, the distance from the sensor 42 to the drum surface 1 is changed, and therefore the compression amount of the buffer 41 is adjusted. Specifically, when striking the drumhead 1, the vibrations of the striking are transmitted to the sensor 42 through the buffer 41, and the sensor 42 outputs the detected signal to a sound source device (Drum Module) (not shown) that controls a sound source based on the detected signal output from the sensor 42 to generate a tone corresponding to the striking and a tone volume corresponding thereto. The utility model discloses an electron percussion instrument can adjust the height of sensor as required to make the compression volume of buffer reach the designing requirement, offset because the harmful effects that the deviation in the electron percussion instrument production process leads to, thereby when guaranteeing to strike the position that the drumhead is the same with the same dynamics, the output signal size of a plurality of samples tends to unanimity, helps improving the tone accuracy of musical instrument. The utility model discloses the structure is succinct, and it is very convenient to adjust.

In one example, the first threads 44b are internal threads and the second threads 45a are external threads (such as shown in fig. 5). In other examples, the first thread 44b may be an external thread and the second thread 45a may be an internal thread, which is not particularly limited as long as the base 45 and the top cover 44 can be engaged by threads.

For example, the main body 8 may be a cylindrical structure having a cylindrical portion 81, which may be made of metal, the drumhead 1 may be a circular structure stretched over the main body 8, and the drumhead 1 may be made of oilpaper, snake skin, sheepskin, cowhide, or the like.

In one example, the electronic percussion instrument further includes a pressing ring 2 provided in a circumferential direction of the drumhead 1 and the main body portion 8 to fix the drumhead 1 and the main body portion 8. In a further example, a plurality of bolts 3 are arranged on the pressing ring 2 at intervals (preferably, evenly spaced), a plurality of main body connecting portions 82 are arranged on the main body portion 8 at intervals in the circumferential direction, and the bolts 3 are arranged in the main body connecting portions 82 in a one-to-one correspondence so as to fix the drumhead 1 and the main body portion 8. Of course, in other examples, the drumhead and the main body portion may be otherwise secured (e.g., the drumhead is large enough to extend downwardly from the upper surface of the main body portion to the sides of the main body portion), or the clamp ring may be otherwise secured (e.g., linked, hinged, etc.) to the drumhead and the main body portion without unfolding one from the other.

By way of example, the electronic percussion instrument further includes a cushion 43 located between the sensor 42 and the top cover 44 and adjacent structures contacting each other, and the cushion 43 may be a circular structure made of a material including, but not limited to, foam plastic to protect the sensor.

In one example, the bumper 41 includes a flexible foam material to prevent the sensor 42 from being damaged by the impact generated when a large force is applied to the drumhead, and the bumper 41 transmits a vibration signal generated when the drumhead 1 is applied to the sensor 42. Further, the shock absorber 41 can also suppress the vibration wave generated when striking the drumhead 1, so that the vibration wave is attenuated faster. In one example, the bumper 41 has a tapered structure, i.e., the area of its upper surface in contact with the drumhead 1 is smaller than the area of its lower surface, which can improve the sensitivity of the drum to impacts.

As an example, the support plate 6 is provided with a central hole 6a and a plurality of insertion holes 6c located in the circumferential direction of the central hole 6a, the plurality of insertion holes 6c are evenly distributed at intervals around the central hole 6a, and the support plate 6 may be a triangular metal plate; the electronic percussion instrument further includes a plurality of elastic washers 7, a main body screw portion 83 (preferably a plurality of elastic washers) is provided in the main body portion 8, and a base connecting portion 45b is provided on the base 45, so that the base 45 is prevented from moving laterally by inserting a main body portion of the screw 5 into a cavity of the base 45 (see fig. 4). The elastic washers 7 are correspondingly clamped in the insertion holes 6c one by one and are fixedly connected to the main body stud part 83 through screws 5; the base connecting portion 45b is inserted into the central hole 6a and connected to the support plate 6 by a screw 5, and the base 45 can rotate around the central hole of the support plate 6 to adjust the relative position of the two as required. In a further example, the elastic gasket 7 comprises one or a combination of a rubber ring and a silicone ring, and the hardness of the elastic gasket 7 is not greater than HA70 degrees.

As an example, as shown in fig. 2 and 3, a top cover guiding hole 44a is provided on the top cover 44, a guiding portion 6b is provided on the supporting plate 6, the guiding portion 6b is inserted into the top cover guiding hole 44a, thereby the rotation of the top cover 44 can be limited, and since the first thread 44b is matched with the second thread 45a, when the base 45 is rotated, the second thread 45a transmits the first thread 44b, and due to the guiding function of the guiding portion 6b, the guiding portion 6b is matched with the top cover guiding hole 44a for limiting, so that the top cover 44 can only move up and down under the matching of the rotating threads, thereby driving the sensor 42 and the buffer 41 to move up and down together. The sensor 42 is disposed on the top cover 44, and the buffer 41 is disposed on the sensor 42, so that when the base 45 is rotated, the height of the sensor 42 can be adjusted, the distance from the sensor 42 to the drumhead 1 is changed, and the amount of compression of the buffer 41 is adjusted. Therefore, the amount of compression of the cushion 41 by the drumhead 1 can be adjusted by rotating the base 45. When each electronic drum is produced, due to errors caused by production, processing and assembly of each component, the compression amount of the buffer 41 of each electronic drum is kept consistent when each electronic drum leaves a factory by adjusting the rotary base 45. During playing, when different electronic drums are used and the same drumhead position is hit by the same force, the compression amount of the buffer 41 is consistent, so that the signal magnitude detected by the sensor 42 is consistent, and the same musical sound volume is realized. Namely, the compression amount of the buffer 41 by the drumhead 1 can be adjusted by rotating the base 45, thereby eliminating assembly errors of each component in the production of the electronic drum.

The inventor conducted a comparative test of the electronic percussion instrument of the present invention with the electronic percussion instrument of the prior art. Referring to fig. 7 and 8, it can be seen that, when the electronic percussion instrument of the present invention is used to strike the drum head at the same position with the same force, the output signals of the multiple samples tend to be consistent; in the electronic percussion instrument in the prior art, when the same position of the drumhead is struck by the same force, the output signals of a plurality of samples have large size deviation. This shows that the electronic percussion instrument of the present invention can effectively reduce the pitch deviation.

The difference between the electronic percussion instrument in the first embodiment and the first embodiment is that, in the first embodiment, the supporting plate 6 and the base 45 are independent structures, when the compression amount of the buffer 41 is to be adjusted, the base 45 needs to be rotated, the top cover 44 can be further provided with a top cover guide hole 44a, the supporting plate 6 is provided with a guide portion 6b, the guide portion 6b is inserted into the top cover guide hole 44a, and due to the guiding effect of the guide portion 6b, the guide portion 6b is matched with the top cover guide hole 44a for limiting, so that the top cover 44 can only move up and down under the matching of rotating threads, and the sensor 42 and the buffer 41 are driven to move up and down together. In the embodiment, the base 45 is fixed to the support plate 6, for example, by screws, the support plate 6 does not need to be provided with a guide portion and the top cover does not need to be provided with a top cover guide hole (specifically, refer to fig. 10), and at this time, the base 44 cannot rotate, so that the top cover 44 can be moved up and down only by rotating the top cover 44 to adjust the height of the sensor 42, and the distance from the sensor 42 to the drum surface 1 is changed, thereby adjusting the compression amount of the buffer 41. Specifically, the electronic percussion instrument in the present embodiment also has the structure of the bumper 41, the sensor 42, the elastic washer 7, the main body 8, the main body stud portion 83, etc., as shown in the first embodiment, the base 45 is fixed to the main body stud portion 83 of the main body 8 by the elastic washer 7 with the screw 5, the top cover 44 is fitted to the base 45, the cushion pad 41 is placed on the top cover 44, the sensor 42 is placed between the bumper 41 and the cushion pad 43, the top cover 44 also has the same first screw thread 44b as in the first embodiment, the base 45 also has the same second screw thread 45a as in the first embodiment, and the first screw thread 44b is engaged with the second screw thread 45 a. By rotating the top cover 44, the top cover 44 moves up and down, so as to drive the sensor 42 and the buffer 41 to move up and down, thereby adjusting the compression amount of the buffer 41 to meet the design requirement. Except for the above differences, the connection manner of other structures of the electronic percussion instrument in this embodiment, such as the drumhead and the main body portion, is the same as that in the first embodiment (for the sake of simplifying the illustration as much as possible, structures such as the drumhead and the pressing ring are not shown in fig. 9), and reference is specifically made to the description in the first embodiment, which is not repeated for the sake of brevity.
