New description: [New technical field] This creation is about a technique for detecting the distance between electronic instruments. [Prior Art] "Compared to the traditional musical instrument system to produce sound through contact between two or more objects, such as electronic drums, cymbals, hi-hats, etc., electronic energy instruments use energy conversion mechanisms. Converting the tapping force or the pedaling force into a telecommunication signal, thereby driving the sound effect processing device to receive and judge the telecommunication φ number, thereby generating a corresponding sound. For example, the electric resistance can be changed by tapping force or pedaling force to adjust the voltage. Or the way of the current, the sound processing device is controlled to produce a corresponding sound, or to make it soundless. Taking the electronic pedal as an example, U.S. Patent No. 6,815,604, the invention name is "Electronic percussion instrument", which is curved. The elastic element changes the shape of the elastic element by the pedaling force applied to the pedal to open or close different numbers of switches, and then controls the resistance value according to the number of opening or closing of the switch to determine the strength of the passed electric signal, thereby controlling The output volume of the electronic wrinkle. In addition, U.S. Patent No. 7,943,841, the name of the invention is "High-hat type electronic pad", which utilizes different treading forces applied to the pedals to actuate the actuating elements disposed at different positions of the lower jaw, respectively The relative circuit switch contacts the way to control the output volume of the electronic pedal. Further, U.S. Patent No. 7,294,778, entitled "Percussi〇n instrument, system, and method with closing position detection", utilizes a conical spring as a force-applying element for controlling the magnitude of the resistance. The pedaling force applied by the crucible determines the contact area of the sensor sheet with the chassis, which in turn controls the output volume of the electronic pedal. U.S. Patent Nos. 7,560,638, 7,820,903, 7,459,626 and 7,655,857 3 M439244 " also employ the same technical principles and will not be further described. The common feature of the above-mentioned patents is that an elastic member such as a rubber or a spring receives an external force such as a tapping force or a pedaling force to deform the elastic member, and the deformation control resistor or the electric signal switch of the elastic member is transmitted through the elastic member. In turn, the purpose of generating a corresponding electronic sound is achieved. However, the above-mentioned elastic components for controlling the resistance or the electrical signal switch can affect the feedback feeling of the user's operation process, and for the electronic musical instrument to make the user feel that the traditional musical instrument requires a higher user, there is Missing. In addition, the contact switch control mode is limited by the number of switches and the position of the switch settings, and cannot achieve multi-stage or even stepless control. Furthermore, the contact type control method is susceptible to the effects of controlling the electronic sound caused by moisture, dirt, loss or rust of the conductive member. [New content] In order to overcome the various shortcomings of the above-mentioned prior art, the present invention provides a non-contact method for detecting the relative distance between electronic musical instrument components and generating different sounds according to the detected different distance values. Or a silent signal, the electronic sound generating device generates a corresponding sound or mute according to the signal. In order to achieve the above object, the present invention provides an electronic musical instrument spacing detecting device, which comprises detecting a distance between an electronic musical instrument component and another electronic musical instrument component, and generating a representative value of the detected distance between the two. a sensing unit of the signal, and receiving the first signal provided by the sensing unit, and configured to convert the first signal into a second signal for generating a corresponding sound or mute according to the preset reference value Signal conversion unit. „ In addition, the present invention provides an electronic musical instrument distance detecting device, comprising: a Hall sensing unit disposed on an electronic musical instrument component, and a magnetic unit disposed on the other electronic musical instrument component, the sensing unit is configured to The distance between the electronic musical instrument component and the other electronic musical instrument component is determined by detecting the distance from the magnetic unit, and a fourth M439244 signal representing the detected distance value is generated, and the sensing is received. The first signal provided by the unit is used to convert the first signal into a signal conversion unit for generating a corresponding second or second signal according to a preset reference value. Compared with the prior art, This creation utilizes non-contact sensing to determine the distance between electronic musical instrument components and generates a signal for driving electronic sound or mute according to the determined distance. According to this, on the one hand, the connection can be overcome. The components are damp, dirty, worn or rusted, which affects the lack of control of electronic sound. On the other hand, the user of the instrument can be closer to the operation of traditional instruments.

Accordingly, when the user changes the relative distance between the pedal 34 and the bottom plate 35 by stepping on the pedal 34 of the electronic pedal 3, the sensing unit 11 can detect the distance between the pedal 34 and the bottom plate 35, thereby generating and utilizing the foregoing A signal and a second signal can cause the electronic pedal 3 to produce a sound or mute effect like a traditional pedal. 9 M439244 As described in the foregoing third embodiment, in particular, in this embodiment, the upper or lower jaw may not be provided; or the upper or lower jaw is provided, but the first or the first The sensing unit or the magnetic unit is provided in the second embodiment; the sensing unit or the magnetic unit as in the first or second embodiment described above may be disposed on the upper or lower jaw while the pedal or the bottom plate is provided with the sensing unit. And optionally, such as a switch unit, to selectively turn on or off a sensing unit disposed on the upper or lower jaw, or a sensing unit disposed on the pedal or the bottom plate. Fifth Embodiment: This embodiment can be applied to various embodiments disclosed in the present specification and other embodiments. In the present embodiment, the sensing unit 11 and the signal conversion unit 12 are integrated into a single device. Sixth Embodiment: Referring to Figures 5a and 5b, this embodiment can be combined with the foregoing embodiments. Specifically, in this embodiment, at least one side of the electronic musical instrument component or the other electronic musical instrument component is opposite to each other, and the buffer unit 14 is disposed. The material of the buffering unit 14 may be foam, rubber, or compression spring, by the buffer unit 14 . The setting can avoid the sound of electronic musical instrument components that may be caused by mutual contact. Since the electronic musical instrument emits sound through the electronic sound source generating unit and the sounding single φ element, instead of sounding the sound of the traditional musical instrument through the instrumental elements such as tapping, impacting, rubbing, etc., if the electronic musical instrument, especially the imitation In the operation of an electronic musical instrument with a traditional musical instrument structure, the electronic musical instrument components emit sounds of different sizes due to contact, which in turn may interfere with the aforementioned electronic sounds, thereby affecting the effect of the electronic musical instrument sound. As shown in FIG. 5a, the lower jaw 32 can be configured as shown in the foregoing step lb. The sensing unit 11 and the signal conversion unit 12 are disposed on the side opposite to the upper jaw 31, and the buffer unit 14 can be disposed under钹32 is opposite to the circumference of one side of the upper jaw 31. When the upper jaw 31 and the lower jaw 32 are relatively moved and brought into contact by the user stepping on the pedal, the possibility that the upper jaw 31 and the lower jaw 32 are in contact may be reduced or eliminated. The sound of the sound.
