In some embodiments, the sliding direction of the button 220 and the mounting groove may be in a direction perpendicular to the central axis of the tube shape of the body 100. The cross-sectional shape of the button 220 may be any shape, such as circular, polygonal (e.g., rectangular, square, etc.), oval, etc.
A plurality of sensing sensors 240 may be disposed at intervals on the button 220. A plurality of sensing sensors 240 may be disposed at intervals on the surface or inside the button 220. Specifically, the plurality of sensing sensors 240 may be disposed at intervals on a side where the button 220 is closed, that is, a side where the user operates the button 220. A plurality of sensing sensors 240 may be distributed in different areas of the button 220 to sense user operations on the different areas. Specifically, the plurality of inductive sensors 240 may correspond to a plurality of areas of the button 220. The plurality of sensing sensors 240 are in one-to-one correspondence with the plurality of regions. The user touching different areas may trigger different inductive sensors 240. The plurality of sensing sensors 240 may be operable to generate corresponding sensing signals based on user manipulation of the area in which they are located. In some embodiments, the inductive sensor 240 may be a touch sensor. In some embodiments, the inductive sensor 240 may be a proximity sensor. The plurality of sensing sensors 240 may be operable to generate sensing signals based on a user's touch or press. The signal controller 400 may be electrically connected with the plurality of sensing sensors 240 of each note key 200. The signal controller 400 may be directly electrically connected to the induction sensor 240 or indirectly electrically connected thereto. When the electronic musical instrument 001 is operated, the induction sensor 240 may generate an induction signal based on a touch or a press of a user; the signal controller 400 may receive the sensing signal, and generate and output a corresponding note control parameter based on the movement of the button 220 and the sensing signal. That is, when the user presses the note key 200 while playing, the note key 200 is pressed, the button 220 moves with respect to the main body 100, and at the same time, the sensing sensor 240 corresponding to the area touched by the user is activated and generates a sensing signal.
In some embodiments, the plurality of sensing sensors 240 may be arranged on the button 220 in a preset shape. The preset shape may be any shape. Wherein the preset shape may be any shape on a plane parallel to the central axis of the tube shape. In some embodiments, the preset shape may include one or more of a ring shape, a straight line perpendicular to the arrangement direction of the plurality of note keys 200, and a straight line parallel to the arrangement direction of the plurality of note keys 200. In some embodiments, the preset shape may be any straight line parallel to the central axis of the tubular shape of the body 100. The plurality of sensing sensors 240 should be spaced apart to prevent a user from touching by mistake. In some embodiments, the distance between adjacent inductive sensors 240 should be within a predetermined range to avoid false touches by the user while avoiding excessive bulk of the device. In some embodiments, the distance between adjacent inductive sensors 240 should be no less than 5mm.
The number of the plurality of induction sensors 240 may be 2 or more. In some embodiments, the number of the plurality of inductive sensors 240 is 2. In some embodiments, the number of the plurality of inductive sensors 240 is 3, or even more, such as 4, 5, 6, etc. In some embodiments, the number of inductive sensors 240 included in different note keys 200 may be the same or different.
In some embodiments, different inductive sensors 240 in the same note key 200 may correspond to different musical tones. The different musical tones may be different in their corresponding note control parameters. For example, when the user touches different sensing sensors 240 in the same note key 200 while pressing the button 220, the signal controller 400 will generate different note control parameters according to different sensing signals corresponding to the different sensing sensors 240, and the different note control parameters will correspond to different sound signals. In some embodiments, when a user touches a plurality of different sensing sensors 240 on the same note key 200 at the same time, the signal controller 400 may generate a plurality of note control parameters based on a plurality of different sensing signals. In some embodiments, when the user touches multiple different sensing sensors 240 on the same note key 200 at the same time, the signal controller 240 may generate a note control parameter based on multiple different sensing signals, where the note control parameter is one of multiple note control parameters corresponding to the multiple different sensing signals or a fusion parameter thereof.
In some embodiments, when a plurality of different sensing sensors 240 in the same note key 200 are simultaneously triggered in different target modes, the signal controller 400 may generate a corresponding note control parameter (such as a flute mode and a schottky mode) based on one of a plurality of different sensing signals corresponding to the plurality of different sensing sensors 240 that are simultaneously triggered, and the signal controller 400 may also generate a corresponding plurality of note control parameters (such as a guitar mode and a piano mode) based on a plurality of different sensing signals corresponding to the plurality of different sensing sensors 240 that are simultaneously triggered. For example, in the flute mode and the schottky mode, when a plurality of different induction sensors 240 in the same note key 200 are simultaneously activated, the electronic musical instrument 001 may emit a corresponding musical tone, i.e., a single tone, from one of the plurality of induction sensors 240. For example, in the piano mode and the guitar mode, when a plurality of different induction sensors 240 in the same note key 200 are simultaneously activated, the electronic musical instrument 001 can simultaneously emit musical tones corresponding to all of the induction sensors 240 in the plurality of induction sensors 240, thereby generating chords. It should be noted that, in the flute mode and the schottky mode, when the plurality of different induction sensors 240 in the same note key 200 are triggered simultaneously, the electronic musical instrument 001 may also simultaneously emit musical tones, i.e. chords, corresponding to all of the induction sensors 240 in the plurality of induction sensors 240.
In some embodiments, different inductive sensors 240 in the same note key 200 may correspond to the same musical tone or may correspond to different musical tones in different target modes. For example, in the guitar mode and the piano mode, different induction sensors 240 may correspond to different musical tones; in the flute mode and the schottky mode, different induction sensors 240 in each note key 200 may correspond to the same musical tone, and different note keys 200 may correspond to different musical tones. When different induction sensors 240 in the same note key 200 correspond to the same musical tone, the corresponding musical tone may be any one of the corresponding musical tones in the plurality of induction sensors 240. The user can make changes and settings to the musical tones corresponding to the different sensing sensors 240. In some embodiments, each note key 200 may also include a circuit board 260. The circuit board 260 may be fixedly installed inside the main body 100. The circuit board 260 may connect the induction sensor 240 and the signal controller 400. I.e., the connection between the induction sensor 240 and the signal controller 400 may be made through the circuit board 260. The circuit board 260 may be electrically connected with the plurality of sensing sensors 240 and generate corresponding touch signals based on the sensing signals. The signal controller 400 may be electrically connected to the circuit board 260 and generate corresponding note control parameters based on the touch signal.
In some embodiments, each note key 200 may further include a resilient means 280. The elastic means 280 may connect the button 220 with the main body 100 to provide a supporting force for the button 220. The user needs to overcome the supporting force provided by the elastic means 280 when pressing the button 220. In some embodiments, the elastic means 280 may be an integral body directly connecting the inner wall of the body 100 and the button 220. At this time, the elastic means 280 may be disposed at a central position of the button 220. At this time, the elastic means 280 may be any material capable of providing elastic force, such as a spring, rubber, etc. In some embodiments, the elastic means 280 may comprise a plurality of elastomers. The plurality of elastic bodies may correspond to the plurality of sensing sensors 240. Two ends of each elastic body are respectively connected with the circuit board 260 and one of the plurality of induction sensors 240. At this time, the elastic body may not only provide a supporting force for the button 220, but also serve as a wire for electrically connecting the induction sensor 240 and the circuit board 260, and may be a metal material such as a metal spring.
In some embodiments, each note key 200 may further include a force detection device 290. A force detecting means 290 may be electrically connected to the circuit board 260 to measure the force with which the button is pressed. The circuit board 260 may generate a corresponding force signal based on the detection result of the force detection device. The circuit board 260 may send the force signal to the signal controller 400. The signal controller 400 may generate corresponding volume parameters and/or tone parameters based on the force signal. The note control parameters may include the volume parameter and the timbre parameter. In some embodiments, a change in distance between the button 220 and the circuit board 260 may reflect the force of the user pressing the button 220. The pressing force may be mapped to a volume parameter. The larger the pressing force is, the larger the volume is; conversely, the smaller the pressing force, the smaller the volume. In some embodiments, the compression force may be mapped to a tone color parameter. For example, the signal controller 400 of the electronic musical instrument 001 may preset the range of the pressing force corresponding to the different tone parameters, so as to generate the different tone parameters according to the pressing force of the user.
In some embodiments, the force detecting device 290 may be a force sensor, mounted on the button 220, and electrically connected to the circuit board 260, for detecting the force with which the button 220 is pressed. The circuit board 260 may generate a corresponding force signal based on the detection result of the force sensor.
In some embodiments, force detection device 290 may include a magnet 292 and a hall sensor 294. Wherein a magnet 292 may be mounted on the button 220 and face the circuit board 260. A hall sensor 294 may be mounted on the circuit board 260 opposite the magnet 292. The hall sensor 294 may detect a moving distance or a moving speed of the magnet 292 and the button 220 with respect to the main body 100 and generate a corresponding distance signal or speed signal. When the user presses the button 220 such that the button 220 moves relative to the circuit board 260, the magnet 292 moves with the button 220 relative to the circuit board 260 and the hall sensor 294. Accordingly, the distance between the magnet 292 and the hall sensor 294 changes. The hall sensor 294 may generate a distance signal or a speed signal based on the received magnetic field signal. The closer the magnet 292 is to the hall sensor 294, the stronger the magnetic field signal received by the hall sensor 294. The circuit board 260 may generate a corresponding force signal based on the distance signal or the speed signal. Wherein, the greater the moving distance or the faster the speed of the button 220, the greater the pressing force.
In some embodiments, the force detection device 290 may include an optoelectronic distance sensor 296. An optoelectronic distance sensor 296 may be mounted on the circuit board 260. The photo distance sensor 296 may detect a moving distance or moving speed of the button 220 with respect to the main body 100 and generate a corresponding distance signal or speed signal. The photo distance sensor 296 may include a photo emitter and a photo receiver. In particular, the photo distance sensor 296 may be mounted on the circuit board 260 and face the button 220. The optical transmitter may transmit an optical signal to 220 and the optical receiver may receive an optical signal transmitted back by the button 220. The circuit board 260 may calculate the intensity of the light signal received by the light receiver, thereby calculating the distance or moving speed between the button 220 and the circuit board 240, and generating a distance signal or a speed signal. Wherein the closer the distance between the button 220 and the circuit board 260, the stronger the optical signal received by the optical receiver. The optical signal may be infrared light, laser light, ultrasonic waves, etc. The circuit board 260 may generate a corresponding force signal based on the distance signal or the speed signal. Wherein, the greater the moving distance or the faster the speed of the button 220, the greater the pressing force.
As described above, the electronic musical instrument 001 can have various modes. Next, we will describe the manner of performance in each mode. For convenience of description, fig. 7 shows a correspondence diagram of a note key 200 and fingering provided according to an embodiment of the present specification. As shown in fig. 7, li denotes a note key 200 corresponding to the index finger of the left hand, lm denotes a note key 200 corresponding to the middle finger of the left hand, la denotes a note key 200 corresponding to the ring finger of the left hand, lc denotes a note key 200 corresponding to the tail finger of the left hand; ri denotes the note key 200 corresponding to the index finger of the right hand, rm denotes the note key 200 corresponding to the middle finger of the right hand, ra denotes the note key 200 corresponding to the ring finger of the right hand, and rc denotes the note key 200 corresponding to the tail finger of the right hand.
In the flute mode, the user can perform with the posture of the flute. I.e., the user may use the flute mouthpiece 830. At this time, the flute type mouthpiece 840 and the microphone 820 are not used. At this time, the playing mode of the electronic musical instrument 001 is set as flute, and the signal controller 400 may set the musical tones corresponding to the plurality of induction sensors 240 of the same note key 200 to the same musical tone, or may set the musical tones corresponding to the plurality of induction sensors 240 of the same note key 200 to different musical tones, as necessary. At this time, the index of the flute mode is as follows: the thumb of the right hand is positioned at the finger rest 860, and the bending tone wheel 850 can be well controlled while the electronic musical instrument 001 is supported; the other four fingers of the right hand press the corresponding four note keys ri, rm, ra and rc respectively; the left thumb slides on the pitch controller 700 to control the initial pitch or the basic pitch of all the note keys 200 while playing a role of fixing the electronic musical instrument 001, and the other four fingers press the corresponding four note keys li, lm, la, and lc, respectively.
In the schottky mode, the user can play by using the posture of the vertical bamboo flute. I.e. the user may use the flute-type mouthpiece 840. At this time, the flute mouthpiece 830 and the microphone 820 are not used. At this time, the electronic musical instrument 001 is set to be a vertical bamboo flute, and the signal controller 400 may set the musical tones corresponding to the plurality of induction sensors 240 of the same note key 200 to be the same musical tone, or may set the musical tones corresponding to the plurality of induction sensors 240 of the same note key 200 to be different musical tones, as necessary. At this time, the schottky pattern is referred to as follows: the thumb of the right hand is positioned at the finger rest 860, and the bending tone wheel 850 can be well controlled while the electronic musical instrument 001 is supported; the other four fingers of the right hand press the corresponding four note keys ri, rm, ra and rc respectively; the left thumb slides on the pitch controller 700 to control the initial pitch or the basic pitch of all the note keys 200 while playing a role of fixing the electronic musical instrument 001, and the other four fingers press the corresponding four note keys li, lm, la, and lc, respectively.
In guitar mode, the user may use the microphone 820, the flute-type mouthpiece 840 and the flute-type mouthpiece 830. At this time, the signal controller 400 may set the musical tones corresponding to the plurality of induction sensors 240 of the same note key 200 to different musical tones as needed. In guitar mode, the electronic musical instrument 001 may perform harmony accompaniment or a guitar-like fingering (solo) effect, while voice may be collected using the microphone 820.
In the guitar mode, a fingering combining left and right hands, that is, a playing mode of a guitar, may be used to map to the electronic musical instrument 001. The thumb of the right hand is positioned at the finger rest 860, and the bending tone wheel 850 can be well controlled while the electronic musical instrument 001 is supported; the other four fingers of the right hand press the corresponding four note keys ri, rm, ra and rc respectively; the left thumb slides on the pitch controller 700 to control the pitches of all the note keys 200 while playing a role of fixing the electronic musical instrument 001, and the other four fingers press the corresponding four note keys li, lm, la, and lc, respectively. The fingering can be freely designed, and can play single tones, double tones, chords, accompaniment, solo and the like, and is convenient to describe, and one fingering is listed here and explained below.
The left and right hands are combined to determine the musical tone of the note key 200. Wherein there may be 12 combinations for each finger combination. The explanation is made with a finger combination of a left index finger and a right index finger. Where li controls the location and ri controls the key location. For li and ri, there are three kinds of musical tones, denoted 1, 2, 3, when each note key is pressed, and no musical tone is output, denoted 0, when not pressed. So, together, li and ri, there are 12 combinations, as shown in table 2:
Similarly, there are 12 other finger pair combinations.
If the initial pitches of the four finger combinations (which can be freely set by the user) are set as follows:guitar mode, musical tones that can be played at the same time are shown in table 3. Of course, since only one tone can be played at a time by each finger combination, each tone in the row corresponding to i, m, a, c in table 3 can only be played at one time. />
By adding the pitch switching of the thumb of the left hand, namely shifting the initial pitch left or shifting one or more semitones right, the gamut of the musical tones which can be played by the musical instrument can be enlarged, and the musical tones with rich and various performances can be played.
In the piano mode, i.e., the playing mode of the piano, is mapped onto the electronic musical instrument 001. The thumb of the right hand slides on the corresponding pitch controller 700 of the right hand to control the starting pitches of all the note keys ri, rm, ra and rc of the right hand, and simultaneously plays a role of fixing the electronic musical instrument 001, and other four fingers respectively press the corresponding four note keys ri, rm, ra and rc; the left thumb slides on the pitch controller 700 corresponding to the left hand, controls the starting pitches of all the left hand note keys li, lm, la and lc, and simultaneously plays a role of fixing the electronic musical instrument 001, and the other four fingers press the corresponding four note keys li, lm, la and lc, respectively. The fingering can be freely designed, and can play single tones, double tones, chords, accompaniment, solo and the like, and is described for convenience, and one of the descriptions is listed here.
The explanation is given with the left hand and the right hand is the same. The left index finger, middle finger, ring finger and little finger have three musical tones, namely 1, 2 and 3, when each finger is pressed down, so the left hand has 12 musical tones. If the left-hand starting pitch is set to 1, the musical tones that can be played by the left hand are shown in table 4:
by adding the pitch switching of the thumb of the left hand, namely shifting the initial pitch left or shifting one or more semitones right, the gamut of the musical tones which can be played by the musical instrument can be enlarged, and the musical tones with rich and various performances can be played.
In summary, the present specification provides an electronic musical instrument 001, by designing the note key 220 as a composite structure of the mechanical buttons 220 and the plurality of induction sensors 240, one note key 200 can play more musical tones without increasing the overall volume of the electronic musical instrument 001, and the electronic musical instrument 001 can play more musical expressive force while being portable, not only can play a single tone, but also can play double tones, chords, accompaniment, solo, etc. The electronic musical instrument 001 provided by the specification can have various working modes, so that the electronic musical instrument 001 can be played in various modes, can be played like a flute, can be played like a vertical bamboo flute, can be played like a guitar or a piano, can be used for accompaniment, solo or playing and singing, can be singed by using the microphone 820, can be used for singing by using the microphone 820, and simplifies the playing method by scientifically planning fingering. Meanwhile, the electronic musical instrument 001 may integrate sound sources (the signal processor 500 and the speaker 810), may directly output the tone of the electronic musical instrument 001, or may use external sound sources through a MIDI interface.
