Description

Technical Field

[0001] The utility model relates to the technical field of sensors, and specifically relates to a sensor for a single pedal hi-hat. Background Art

[0002] A hi-hat is an electronic percussion instrument, which usually includes a cymbal and a vibration sensor arranged in the inner cavity of the cymbal. The vibration sensor is connected to an external sound source. During performance, the performer steps on a foot pedal to strike the cymbal. After the vibration sensor installed in the cymbal detects the vibration on the cymbal, it transmits the detected signal to the external sound source and generates different timbres, thereby realizing its function.

[0003] Since when the performer steps on the foot pedal to strike the electronic cymbal, in addition to the sound emitted by the external sound source, the vibration of the cymbal will also generate sound, which will cause a slight deviation in the generated timbre and affect the performance effect. In order to avoid the vibration sound of the cymbal, a rubber ring for reducing vibration is arranged between the upper cymbal and the lower cymbal, but this will also affect the detection accuracy of the vibration sensor and lack the real effect of cymbal performance.

[0004] For the electronic simulation hi-hat in the related art, such as the Chinese patent application with the publication number CN102543053A and the name of electronic simulation hi-hat, it discloses that the displacement change of the cymbal is used to trigger the change of the electrical signal of the optoelectronic sensor device, so as to sense different vibrations generated by striking the cymbal and emit different timbres. Specifically, when the cymbal moves downward and the displacement transmission member moves downward, its two extending parts extend into the empty space in the middle of the "U"-shaped optoelectronic sensor device, making the optoelectronic sensor device conduct and generate an electrical signal. The displacement change of the cymbal moving downward causes the number of optoelectronic sensor devices that are conducted to change accordingly, and different electrical signals are also generated accordingly. Another example is the Chinese patent application with the publication number CN209103810U and the name of hi-hat displacement detection component, device and electronic percussion instrument, which includes a displacement detection circuit and also includes a displacement detection terminal connected to the sensor and a preset number of resistors; the preset number of resistors are connected in series, and the detection switch is connected in parallel at both ends of the preset number of resistors; the displacement detection terminal is connected to the series-connected resistors and is used to detect the displacement of the hi-hat. That is, it discloses that the change of the cymbal stroke and the resistance tend to change linearly, and the cymbal stroke or displacement can be feedback through the resistance change.

[0005] Therefore, how to provide a hi-hat sensor that can feedback the real movement position of the cymbal only by using the change of the current signal without using a vibration sensor, so as to accurately output a signal and then generate a standard timbre is a technical problem that needs to be solved urgently at present. Summary of the Invention

[0006] The technical problem to be solved by the utility model is to provide a single pedal hi-hat sensor that can accurately output a signal and then generate a standard timbre.

[0007] The technical solution of the present utility model is to provide a sensor for an independent hi-hat cymbal having the following structure:

[0008] It includes a housing and a sliding rheostat assembly disposed within the housing. The housing is provided with a shaft hole penetrating its upper and lower end faces. A guiding connecting shaft is disposed within the shaft hole, and the lower end of the guiding connecting shaft extends outside the housing for connecting with a hi-hat cymbal stand. A bushing and a spring are sleeved on the guiding connecting shaft. The bushing is slidably connected to the guiding connecting shaft. One end of the spring abuts against the lower end face of the bushing, and the other end is connected to the guiding connecting shaft. The bushing includes a sleeve and a bushing seat. The upper end of the sleeve extends outside the housing for connecting with the upper cymbal. The lower end of the sleeve is detachably connected to the bushing seat. The sliding rheostat assembly includes a resistance plate and a conductive brush in contact with the resistance plate. The bushing seat is connected to the conductive brush for driving the conductive brush to move on the resistance plate.

[0009] After adopting the above structure, the sensor for an independent hi-hat cymbal of the present utility model has the following advantages compared with the prior art:

[0010] When hitting the upper cymbal to make it move up and down, it will drive the bushing seat to slide up and down along the guiding connecting shaft through the sleeve, and then drive the conductive brush on the bushing seat to move on the resistance plate. When the conductive brush moves on the resistance plate, the current in the circuit will change accordingly. The position of the up-and-down movement of the upper cymbal can be accurately judged through the change of the current, so that a signal can be accurately output to generate a standard tone. The bushing is set into two parts, namely a sleeve and a bushing seat. When replacing the conductive brush in the future, only the bushing seat part needs to be replaced, saving costs.

[0011] Preferably, a first convex ring is provided on the outer peripheral wall of the sleeve near its lower end. The outer diameter of the first convex ring is larger than the inner diameter of the shaft hole. The upper end of the bushing seat is tightly and fittingly connected to the lower end of the sleeve, and the upper end face of the bushing seat abuts against the first convex ring. The first convex ring can play a limiting role to prevent the sleeve from disengaging from the housing.

[0012] Preferably, a radially extending protrusion is provided on the outer peripheral wall of the bushing seat, and the conductive brush is detachably connected to the protrusion.

[0013] Preferably, the housing includes a base and a top cover, and the base and the top cover are connected by screws. Setting the housing into two parts, namely a base and a top cover, facilitates the assembly of each component.

[0014] Preferably, a first thread is provided in the shaft hole of the base, and a second thread is provided on the outer peripheral wall of the guiding connecting shaft. The second thread is threadedly connected to the first thread. Through the cooperation of the second thread and the first thread, the guiding connecting shaft can be firmly fixed on the base.

[0015] Preferably, a second convex ring is provided on the outer peripheral wall of the guiding connecting shaft below the second thread, and the outer diameter of the second convex ring is larger than the inner diameter of the shaft hole. The second convex ring can play a positioning role. When screwing the guiding connecting shaft onto the base, it is only necessary to screw it until the second convex ring abuts against the lower end surface of the base to determine that the guiding connecting shaft is screwed in place.

[0016] Preferably, a third thread is provided on the outer peripheral wall of the lower end of the guiding connecting shaft, and the third thread is used to connect to the hi-hat stand. Description of the Drawings
