Description

Technical Field

[0001] The invention relates to a musical instrument, in particular to an electronic percussion instrument device which can simulate the sound of a real percussion instrument. Background Art

[0002] Electronic percussion is a form of music that uses electronic equipment to simulate the sounds of traditional percussion instruments. Its main technologies include: sampling technology, digital signal processing technology, triggering technology and music digital interface (MIDI) technology (hereinafter referred to as MIDI). Sampling technology is to collect the sounds of real traditional percussion instruments, digitize them and store them in electronic devices, so that electronic percussionists can simulate the sounds of traditional percussion instruments by striking electronic equipment; digital signal processing technology can process and change the collected percussion instrument sounds, such as adding reverberation or adjusting the pitch.

[0003] The trigger technology is because electronic percussion instruments usually use capacitors, pressure sensors or switches to trigger the sound, and the trigger controls the start, duration and decay of the sound. MIDI technology is a digital interface standard that allows electronic percussion instruments to be connected to other electronic instruments, computers or other devices to achieve the transmission and control of music data.

[0004] Although electronic percussion instruments have advantages in many aspects, such as portability, programmability, and versatility, they also have some disadvantages:

[0005] 1. Compared with the sound of traditional percussion instruments, the sound of electronic percussion instruments is not warm and natural enough. The sound produced by electronic percussion instruments is not as real as the sound of traditional percussion instruments.

[0006] 2. For musicians who need to play traditional percussion instruments, the use of electronic percussion instruments may not be able to fully express the true characteristics of the music of traditional percussion instruments.

[0007] 3. The electronic percussion instruments on the market currently focus on electronic drums and drum machines, while other percussion instruments such as shakers, rain machines, castanets, and tambourines are less common.

[0008] In the electronic musical instrument proposed in the past, a sensor is provided on a rod-shaped member, and a player holds the member with his hand and swings it, and the sensor detects the movement of the member, so that the electronic musical instrument produces a sound. In particular, in the electronic musical instrument, the rod-shaped member has a shape like a drumstick or a Japanese drumstick, and produces the sound of the percussion instrument in response to the player's action of hitting the drum or Japanese drum.

[0009] In the prior art, U.S. Patent No. 5,058,480 discloses a performance device, in which an acceleration sensor is provided on a rod-shaped member, and when the output from the acceleration sensor (acceleration sensor value) reaches a predetermined threshold value and a predetermined time has passed, a musical sound is emitted. However, there are some defects in this U.S. patent: it is difficult to achieve the change of musical sound desired by the performer by controlling the emission of musical sound based on the acceleration sensor value of the rod-shaped member.

[0010] Japanese Patent Laid-Open No. 2007-256736 discloses a device that can emit multiple timbres. The device uses a geomagnetic sensor to emit a certain timbres according to the direction of a rod-shaped member. The device produces a change in the musical sound according to the direction when the performance starts, that is, when the rod-shaped member is swung. However, at the beginning of the performance, that is, the time point when the rod-shaped member is swung, the changed musical sound has been determined and cannot show the change of the musical sound at different time points. Summary of the invention

[0011] In view of the defects of the prior art, the main purpose of the present invention is to provide an electronic percussion instrument device, which uses a motion sensor to detect the current operation mode of the percussion instrument device, calculates the corresponding sound frequency according to the current operation mode, and then generates a simulation signal according to the sound frequency. The processing and calculation unit of the electronic percussion instrument device then compares the simulation signal with the sampled sound frequency in the sampled data database to obtain the simulation sound that is closest to the real sound and output it.

[0012] Another object of the present invention is an electronic percussion instrument device, which uses a motion sensor to detect the change in the angle value of the electronic percussion instrument device between different time points, and determines the current movement speed of the electronic percussion instrument device based on the change in the angle value. The frequency of the current movement speed is then calculated by simulating the inertia generated by the user when swinging or moving, and the sound corresponding to the frequency is output after the frequency is processed by a filter.

[0013] According to the above purpose, the present invention discloses an electronic percussion instrument device, characterized in that it includes: a motion sensor for sensing the current state of the electronic percussion instrument device and generating angle values ​​X, Y, and Z based on Euler angles at the same time; a processing and calculation unit for calculating the sound frequency corresponding to the angle values ​​X, Y, and Z according to the angle values ​​X, Y, and Z and the current state of the electronic percussion instrument device, and the processing and calculation unit generates the angle value changes ΔX, ΔY, and ΔZ of the electronic percussion instrument device in a non-static state at a preset time interval, and obtains an elasticity value K by using an elasticity algorithm for the angle value changes ΔX, ΔY, and ΔZ; an electronic oscillator for comparing the sound frequency corresponding to the current state with the sampled sound frequency stored in the sampling storage unit to obtain a simulation signal; a filter for passing the elasticity value K through the filter to obtain a frequency signal with a specific bandwidth; and a sound output unit for integrating and converting the simulation signal and the frequency signal with the specific bandwidth to obtain a simulated sound and output the simulated sound.

[0029] In order to make the purpose, technical features and advantages of the present invention more understandable to those skilled in the relevant technical field and to implement the present invention, the technical features and implementation methods of the present invention are specifically explained in conjunction with the attached drawings, and preferred embodiments are listed for further explanation. The drawings compared in the following text are for expressing the features of the present invention, and are not and do not need to be fully drawn according to the actual situation. The technical content familiar to those skilled in the art in the description of the implementation method of this case is not described again.

[0030] First, please also refer to Figure 1A and Figure 1B . Figure 1A is a block diagram showing an embodiment of an electronic percussion instrument device, and Figure 1B The present invention is a flowchart showing the steps of producing sound by an electronic percussion instrument device. Figure 1A In the embodiment, the electronic percussion instrument device 1 is at least composed of a motion sensor 10 , an electronic oscillator 12 , a sampling storage unit 14 , a processing and calculation unit 16 and a sound processing unit 18 .

[0031] In this embodiment, the motion sensor 10 is used to perform step S10: generate angle values ​​of X (roll), Y (pitch), and Z (yaw) based on Euler angles according to the action of the electronic percussion instrument device. In this step, when the user uses the electronic percussion instrument device 1, the motion sensor 10 senses the angle changes of the electronic percussion instrument device 1 on the three axes of X, Y, and Z when the electronic percussion instrument device 1 changes from a static state to an action.

[0032] It should be noted that in the present invention, when the user shakes the electronic percussion instrument device 1, the motion sensor 10 will generate angle values ​​of X (roll), Y (pitch), and Z (yaw) based on the Euler angle according to the shaking of the electronic percussion instrument device 1. It should be noted that X (roll) generally refers to the angle of rotation around the X-axis, Y (pitch) generally refers to the angle of rotation around the Y-axis, and Z (raw) generally refers to the angle of rotation around the Z-axis. For the rotation of the electronic percussion instrument device 1, the three angles of X (roll), Y (pitch), and Z (yaw) can define the rotation of the electronic percussion instrument device 1. However, the electronic percussion instrument device 1 disclosed in the present invention achieves its purpose through the application of Euler angles. The detailed algorithm and mathematical theory of Euler angles are not the focus of the present invention and will not be further described here.

[0033] Then, step S11 is performed: judging the current state of the electronic percussion instrument device 1 according to the angle values ​​of X (roll), Y (pitch), and Z (yaw). In this step, the current state may be, for example, shaking the electronic percussion instrument device 1, touching the electronic percussion instrument device 1, or shaking and touching the electronic percussion instrument device 1 at the same time. It should be noted that the "shaking" referred to here may be shaking the electronic percussion instrument device 1 up, down, left, or right at a regular or irregular frequency; the "touching" is because a plurality of touch buttons (not shown in the figure) are provided on the shell (not shown in the figure) of the electronic percussion instrument 1, and these touch buttons (not shown in the figure) each have their corresponding notes, so the user can make the electronic percussion instrument device 1 move by touching. When the touch button of the shell is touched, the dynamic sensor 10 will receive the note corresponding to the touch button, and then calculate the corresponding sound frequency based on this signal.

[0034] Therefore, when step S11 determines that the current state of the electronic percussion instrument device 1 is shaking (step S122), the processing and calculation unit 10 generates a sound frequency corresponding to the angle values ​​X (roll), Y (pitch), and Z (yaw) of the current state of the electronic percussion instrument device 1 through a pink noise algorithm (step S1222) (step S13).

[0035] When step S11 determines that the current state of the electronic percussion instrument device 1 is a touch key (step S124), the processing and calculation unit 10 calculates the sound frequency of the note of the corresponding touched key through the note conversion frequency formula (step S1242) (step S13), wherein the note conversion frequency formula is 440.0f*powf(2.0, (note number)-57) / 12.0, in which 440.0 represents the standard tone A3 frequency in music, f represents that the current number is a decimal type, and the note number is a positive integer in the range of 0-127.

[0036] When step S11 determines that the current state of the electronic percussion instrument device 1 is shaking and touching the button (step S126), the processing and calculation unit 10 simultaneously calculates the sound frequency of the electronic percussion instrument device 1 when it is shaken and touched through the pink noise algorithm and the note conversion frequency formula (step S13).

[0037] Then step S14: vibrate according to the sound frequency corresponding to the current state to generate a simulated audio frequency. In this step, the electronic oscillator 12 converts the sound frequency into a simulated audio frequency through a sine wave or square wave electronic circuit according to the sound frequency obtained in step S1222, step S1242 or step S1262 (step S13). In the embodiment of the present invention, the electronic oscillator 12 is an audio oscillator, and its audio range is between 16hz-20khz.

[0038] Then in step S15: the simulated audio frequency is compared with the sampled sound frequency to generate a simulated signal. In this step, the processing and operation unit 16 compares the simulated audio frequency obtained from step S15 with the sampled sound frequency stored in the sampling storage unit 14 to obtain the simulated signal. It should be noted that in the embodiment of the present invention, the sampling storage unit 14 is used to store at least one real sound frequency, which is collected by the sounds emitted by real shakers, rain sounds, drum hammers, drum sticks, and tambourines, and is stored in the sampling storage unit 14. The processing and operation unit 16 compares the simulated audio frequency with various real sound frequencies stored in the sampling storage unit 14 to select the closest real sound frequency as the simulated signal.

[0039] Finally, step S16: outputting the simulation signal to emit the simulation audio. In this step, the processing and calculation unit outputs the simulation signal obtained in step S15 via the sound output unit 18 to emit the processed simulation audio.

[0040] Please also refer to Figure 2A and Figure 2B . Figure 2A is a block diagram showing another embodiment of an electronic percussion instrument device, and Figure 2B 1 is a schematic flow chart showing another embodiment of the electronic percussion instrument device producing sound. Figure 2A In the embodiment, the electronic percussion instrument device 2 at least comprises a motion sensor 20, a processing and calculation unit 21, a high-pass filter 22, a low-pass filter 23, a band-pass filter 24 and a sound output unit 25.

[0041] In this embodiment, the motion sensor is used to perform step S20: generate angle values ​​of X (roll), Y (pitch), and Z (yaw) based on Euler angles according to the action of the electronic percussion instrument device. In this step, when the user uses the electronic percussion instrument device 1, the motion sensor 10 senses the angle changes of the electronic percussion instrument device 1 on the three axes of X (roll), Y (pitch), and Z (yaw) when the electronic percussion instrument device 1 changes from a static state to an action.

[0042] Step 21: Calculate the angle value change within the preset time interval. In this step, the processing and calculation unit 21 sets the time point when the electronic percussion instrument device 2 is in a static state as t0, and its angle values ​​at t0 are X0, Y0, and Z0. The time point when the electronic percussion instrument device 2 is in action is set to t1, and the angle values ​​at t1 are X1, Y1, and Z1. Therefore, the angle value change between the preset time interval t1-t0 can be regarded as the angle value change in the non-static state, which are ΔX=X1-X0, ΔY=Y1-Y0, and ΔZ=Z1-Z0 respectively. In the embodiment of the present invention, the preset time interval is 60 milliseconds.

[0043] Step S22: Determine the speed state of the electronic percussion instrument device when it is not stationary according to the angle value variation in the non-stationary state. In this step, the processing and calculation unit 21 calculates the angle value variation in the non-stationary state according to each preset time interval, and determines the speed state of the electronic percussion instrument device according to the angle value variation. When the range of the angle value changes ΔX, ΔY, ΔZ is between 0.5<ΔX<1, 0.5<ΔY<1, 0.5<ΔZ<1, the angle value change of the electronic percussion instrument device 2 in the non-stationary state is fast (step S232); when the range of the angle value changes ΔX, ΔY, ΔZ is between 0<ΔX<0.5, 0<ΔY<0.5, 0<ΔZ<0.5, the angle value change of the electronic percussion instrument device 2 in the non-stationary state is slow (step S234); when the range of the angle value changes ΔX, ΔY, ΔZ is 0=ΔX, 0=ΔY, 0=ΔZ, the angle value change of the electronic percussion instrument device in the non-stationary state is uniform (step S236).

[0044] Next, in step S24, the angle value changes ΔX (roll), ΔY (pitch), and ΔZ (yaw) in the non-stationary state are calculated by an elasticity algorithm to obtain an elasticity value K. In this step, the processing and calculation unit 21 brings the above-obtained ΔX (roll), ΔY (pitch), and ΔZ (yaw) into the elasticity value K calculation to simulate the inertia generated by the user when swinging or moving. The elasticity value formula is K = (1 + 2 + 3 (-1 + ΔX) (-1 + ΔX) 2+1+(2+3(-1+ΔY))(-1+ΔY) 2 +1+(2+3(-1+ΔZ))(-1+ΔZ) 2 / 3.

[0045] Step 25: Select a filter according to the change in the angle value and calculate the frequency range of the filter and the elasticity value to obtain the processed simulation frequency. In this step, the speed of the electronic percussion instrument device 2 in the non-stationary state can be obtained from the aforementioned step S22, whether it is fast, slow or uniform. The filter to be passed is selected according to the speed. If the speed is fast, the high-pass filter 22 is selected, and its frequency range is 6khz-8khz. The processed simulation frequency range is 6khz+(8khz-6khz)*K after calculation with the elasticity value K; if it is slow, the low-pass filter 23 is selected, and its frequency range is 20hz-1khz. The processed simulation frequency range is 20hz+(1khz-20hz)*K after calculation with the elasticity value K; if it is uniform, the band-pass filter 24 is selected, and its frequency range is 20hz-20khz. The processed simulation frequency range is 20khz+(20khz-20hz)*K after calculation with the elasticity value K.

[0046] Step S26: Output the simulation frequency range to emit the simulation audio. In this step, the processing and calculation unit outputs the processed simulation frequency range obtained in step S25 via the sound output unit 18 to emit the processed simulation audio. For example, when the speed of the electronic percussion instrument device 2 in the non-stationary state is fast, and the simulation frequency range is 6khz+(8khz-6khz)*K, the simulation audio output is a strong and short rustling sound. When the speed of the electronic percussion instrument device 2 in the non-stationary state is slow, and the simulation frequency range is 20hz+(1khz-20hz)*K, the simulation audio output is the sound of water flowing slowly like rain. When the speed of the electronic percussion instrument device 2 in the non-stationary state is uniform, and the simulation frequency range is 20khz+(20khz-20hz)*K, the simulation audio output is a steady rustling sound.

[0047] Please also refer to Figure 3A and Figure 3B . Figure 3A is a block diagram showing another embodiment of an electronic percussion instrument device, and Figure 3B FIG. 1 is a schematic flow chart showing the steps of another embodiment of the electronic percussion instrument device for producing sound. Figure 3A In the figure, the electronic percussion instrument device 3 is composed of at least a motion sensor 30, a processing and operation unit 31, an electronic oscillator 32, a sampling storage unit 33, a filter unit 34 composed of a high-pass filter 342, a low-pass filter 344 and a band-pass filter 346, and a sound processing unit 35.

[0048] In this embodiment, the aforementioned Figure 1A Electronic percussion instrument device 1 and Figure 2A The electronic percussion instrument device 2 is integrated, and the functions and effects of each component are the same as those described above and will not be described in detail. Figure 3B In step S30 to step S35, Figure 1B Steps S10 to S15 are the same as in Figure 2B Steps S21 to S26 are the same.

[0049] and Figure 1A , Figure 1B and Figure 2A , Figure 2B The difference is that in step S50, the simulation signal obtained in step S35 and the simulation frequency obtained in step S45 are integrated to obtain a simulated sound. This simulated sound also has the actual current state of the electronic percussion instrument device 3, such as shaking, touching, or shaking and touching the electronic percussion instrument device 3 at the same time. Instead of only obtaining the operating state of the electronic percussion instrument device 3 through data simulation, the speed of the electronic percussion instrument device 3 in the non-stationary state at the default time interval is used to further simulate the sound generated by the actual striking, shaking, and swinging speed of the real percussion instrument device. Compared with the electronic percussion instrument devices currently on the market, the electronic percussion instrument devices 1, 2, and 3 disclosed in the present invention all take into account the user's usage scenario and the state of the percussion instrument device when in use, and can produce sounds closer to real percussion instruments.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of rights of the present invention. At the same time, the above description should be understandable and implementable for professionals in the relevant technical field. Therefore, other equivalent changes or modifications that do not deviate from the spirit disclosed by the present invention should be included in the scope of the patent application.
