Abstract
Description
Technical Field
[0001] The present invention relates to music equipment, and particularly to electronic musical instruments and their usage methods. Background Art
[0002] Drums are percussion instruments. Drums are generally played by hitting the drumhead and the drum body with hands or with drumsticks. Due to the tactile characteristics of drums and their ease of use, they are often used in music therapy, especially hand drums.
[0003] Music education mainly focuses on teaching music, enhancing musical sense, increasing music knowledge, or learning musical instruments. Music therapy is a professional program in auxiliary medicine. Music therapists use music in a planned and creative way to achieve specific treatment goals, including the physiological, psychological, emotional, cognitive, social, and communication needs of individuals, promoting, improving, or maintaining the physical and mental health and quality of life of individuals. It can be understood as using music as a medium to achieve treatment goals other than musical abilities, such as social skills, emotional awareness, communication skills, fine and gross motor skills, and sustained concentration.
[0004] Currently, the service scope of music therapy mainly covers aspects such as preschool education, special education, medical systems, mental health, physical rehabilitation, palliative care, and elderly services. Generally, the diseases for which music therapy is used to improve symptoms and their emotional and behavioral problems include: attention deficit / hyperactivity disorder (ADD / ADHD); autistic spectrum disorder; dyslexia / learning disorder; developmental delay; intellectual disability; schizophrenia / psychosis; depression; other emotional diseases; other mental diseases; cognitive impairment / brain degeneration; physical disabilities; long-term patients; terminal patients; rehabilitation after stroke, etc.
[0005] The inventors have found that there are at least the following problems in the prior art:
[0006] During the process of participating in music therapy, it is found that although traditional wooden box drums used for music therapy are very easy to produce sounds, when in use, traditional drums usually play a single instrument sound, which is not only relatively simple and boring in form, but also direct contact with the drum is required, such as hitting or patting. For patients undergoing music therapy, they usually have various physical, psychological, and mental problems. It is very likely that they do not accept or are slow to accept the things around them. If direct contact with the drum is required to interact, it is very likely that music therapy cannot be effectively and smoothly carried out. Summary of the Invention
[0007] The purpose of the present invention is to provide an electronic musical instrument and its usage method, such that during the process of music therapy, even if the patient does not touch the instrument, they can perceive music and conduct music performance interactions.
[0008] To solve the above technical problems, an embodiment of the present invention provides an electronic musical instrument, including a box body, sound effect accessories, sensors, an audio sound processor, and a micro programmable processor located inside the box body. Among them, the sound effect accessories are arranged inside the box body to divide the box body into different percussion areas; the micro programmable processor is electrically connected to the audio sound processor and the sensors. The sound source module of the audio sound processor receives external real-time music, and the sensors sense the distance and movement of the performer to control the playback sound effect of the real-time music.
[0009] In addition, the sound effect accessories include a phase inverter tube, a snare drum rattler wire, and / or a sand belt, which are arranged inside the box body to divide the box body into different percussion areas, including: an area near the phase inverter tube, a bass area that can produce a bass drum sound when struck; an area far from the phase inverter tube, a treble area that can produce a higher-pitched soundboard sound when struck; and two edge areas on the long side of the wooden drum box, a patting area that can produce the effect of a vibrating rattler wire and a sand belt in a snare drum when lightly struck; the effect of lightly patting the rattler wire and vibrating the sand belt in the edge area where the snare drum rattler wire and / or the sand belt is located is more obvious than that in the other edge area.
[0010] In addition, the audio sound processor includes a sound effect module, and the sound effect module performs various different sound effect processes on the sound effect of the real-time music; the sound effect processes include one or more of the following: reverberation, echo, distortion, and also include a high and low frequency equalizer and a microphone amplifier.
[0011] In addition, the electronic musical instrument further includes: a sound amplifier and a resonance speaker. Among them, the real-time music that has completed the sound effect process by the audio sound processor is amplified in power by the sound amplifier to the resonance speaker. The resonance speaker uses the resonance principle to make the box body become an independently applied speaker to play the real-time music.
[0012] In addition, when the sensor senses the performer, the real-time music starts to play; if the sensor senses that the performer is approaching, the sound of the real-time music becomes louder; if the sensor senses that the performer is moving away, the sound of the real-time music becomes smaller; when the sensor does not sense the performer, the playback of the real-time music stops.
[0013] In addition, the sensor uses an ultrasonic sensor; the electronic musical instrument further includes: an external sensor connector, and other sensors can be externally connected through the external sensor connector to control the playback of the real-time music; the other sensors include one or more of the following: a vibration sensor, an infrared sensor, and a grip sensor.
[0014] In addition, the micro programmable processor is configured with a reset function, and the restart of the micro programmable processor is controlled by a reset button provided on the wooden box body.
[0015] In addition, the micro programmable processor is electrically connected to a reduction motor, and the reduction motor uses a slow motor.
[0016] In addition, the electronic musical instrument is an electronic cajon; the electronic cajon further includes: a self-rotating ornament to attract a player to approach the cajon to participate in playing.
[0017] An embodiment of the present invention provides a method of using the electronic cajon as described above, including: turning on the sensor of the electronic cajon; when the distance of the player is sensed within a set range, the micro programmable processor controls the audio sound processor to play real-time music through a sound amplifier and a resonance speaker; within the set range, according to the sensed distance of the player from the cajon, control the sound change of the real-time music.
[0018] In the present invention, by improving the traditional cajon, a micro programmable processor is built into the cajon. The micro programmable processor is electrically connected to an ultrasonic sensor for sensing the distance and movement of a patient to control the playback sound effect of real-time music. When a patient is sensed, the real-time music starts to play. When the patient is sensed to be approaching, the sound of the real-time music becomes louder. When the patient is sensed to be moving away, the sound of the real-time music becomes smaller. And when no patient is sensed, the playback of the real-time music stops. In this way, even if the patient undergoing music therapy does not touch the cajon, they can perceive the music and interact in music performance, achieving the purpose of music therapy.
[0019] In the present invention, the problem to be solved is how to attract the patient undergoing music therapy to approach the cajon and perform. Regarding this technical problem, there are many influencing factors. For example, the patients undergoing music therapy usually do not have the ability to play. If they just play randomly, the music therapy effect will not be ideal. Then, in the present invention, an audio sound processor is electrically connected to the micro programmable processor. The sound source module of the audio sound processor receives the externally connected real-time music in a wired or wireless manner. In addition, the sound effect module of the audio sound processor performs various different sound effect processes on the sound effect of the real-time music; the real-time music after the sound effect process by the audio sound processor is amplified in power to the resonance speaker through a sound amplifier, and the resonance speaker uses the resonance principle to play the real-time music. That is, the music produced by the cajon is not played by the patient undergoing music therapy, but the playback sound effect of the externally connected real-time music is controlled by sensing the distance and movement of the patient. Therefore, during music therapy, the music therapist can not only use music in a planned and creative way to achieve specific treatment goals, but also attract the patient undergoing music therapy to approach the cajon for interaction without touching the cajon, better achieving specific treatment goals.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will elaborate on each embodiment of the present invention with reference to the drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present invention, many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented.
[0027] The first embodiment of the present invention relates to an electronic musical instrument. In a specific embodiment, the electronic musical instrument is an electronic cajon. As Figure 1 shown, the electronic cajon includes a box body 1, a phase inverter tube 2 located inside the box body, an ultrasonic sensor 3, an audio sound processor 4, and a micro programmable processor 5.
[0028] The box body is preferably a cuboid, including an upper panel, a lower bottom plate and peripheral plates. For convenient carrying, the length range of the box body is 300 - 400 mm (preferably 380 mm), the width range is preferably 200 - 300 mm (preferably 240 mm), and the height range is preferably 80 - 150 mm (preferably 103 mm). The thickness of the wooden boards: for the four peripheral plates, the range is preferably 5 - 10 mm (preferably 7 mm), for the lower bottom plate, the range is preferably 2 - 6 mm (preferably 4 mm), and for the upper panel, the range is preferably 2 - 6 mm (preferably 3 mm). The preferred material for the upper panel is basswood, and the preferred materials for the lower bottom plate and the peripheral plates are pine woods. Of course, the box body can also be of other shapes, and the length, width, and height of the box body as well as the thickness of the wooden boards can also be other values, and other materials can also be selected for the wooden boards, which are not specifically limited herein. Patterns can be printed on the wooden boards or hand-painted, which are not specifically limited herein.
[0029] Different from general traditional wooden box drums, the present invention adopts a sealed port design and adds a phase inverter and a snare wire / sand strip 6 to the wooden box drum. After repeated calculations, adding two phase inverters on one side of the wooden box drum can generate a low frequency of about 60 hz when struck. Preferably, the placement distance range between the two phase inverters is 50 - 100 mm (preferably 85 mm). Adding two snare wires / sand strips inside the wooden box drum, nailed flat on wooden pieces and placed on the other side opposite to the phase inverter, can produce the effect of the snare wire vibrating the sand strip in snare drum music when lightly struck. Preferably, the width range of each is 30 - 80 mm (preferably 50 mm), and the length range is 100 - 200 mm (preferably 145 mm).
[0030] As Figure 2 shown, by adding a phase inverter and a snare wire / sand strip, the present invention divides the wooden box drum into three different striking areas, which can produce different sound effects. Specifically,
[0031] (I) The bass area 100 is the area close to the phase inverter. When struck, it can produce a bass drum sound of about 60 hz.
[0032] (II) The treble area 200 is the area far from the phase inverter. When struck, it can produce a higher-pitched soundboard sound when the wooden board is slapped.
[0033] (III) The light strike area 300 is the two edge areas along the long side of the wooden drum box. When lightly struck, it can produce the effect of the snare wire vibrating the sand strip in snare drum music. When lightly patted, the effect of the snare wire vibrating the sand strip in the corresponding area of the snare wire / sand strip is more obvious than that on the other edge area.
[0034] Please continue to refer to Figure 1, a microprogrammable processor is electrically connected to an ultrasonic sensor and an audio sound processor. Specifically, the audio sound processor is electrically connected to the microprogrammable processor when powered on. The sound source module of the audio sound processor can receive external real-time music wired or wirelessly (by connecting a Bluetooth wireless module). The sound effect module of the audio sound processor performs various different sound effect processes on the sound effects of the real-time music. For example, 16 different sound effects are selected, including reverberation, echo, distortion, and also include sound effect processes such as high and low tone equalizers and microphone amplifiers.
[0035] Furthermore, the real-time music after the sound effect processing by the audio sound processor is amplified in power to the resonance speaker 8 through the sound amplifier 7. The resonance speaker uses the resonance principle to make the wooden box drum become an independently applied speaker and play the real-time music;
[0036] The microprogrammable processor is electrically connected to the ultrasonic sensor and can sense the distance and movement of the performer to control the playback sound effect of the real-time music. For example, when the performer is sensed, the real-time music starts to play. If the performer is sensed to be approaching, the sound of the real-time music becomes louder. When the performer is sensed to be moving away, the sound of the real-time music becomes smaller. When the performer is not sensed, the playback of the real-time music stops.
[0037] As Figure 3 shown, the microprogrammable processor is configured with a reset function. When the reset button 9 is pressed, the built-in microprogrammable processor will be restarted; the indicator light 10 is lit to indicate that the real-time music is being played; the ultrasonic sensor switch button 11 is used to turn on and off the ultrasonic sensor.
[0038] As Figure 4 shown, the sound effect selection knob 12 can select 16 different sound effects; the sound effect output knob 13; the Hi-Lo / high and low tone equalizer; the volume control knob 14; the switch button 15 includes a sound effect module switch, a main power switch, a built-in microprogrammable processor switch, a built-in amplifier switch, and a Bluetooth output switch; the USB port 16 is used to update the software of the built-in microprogrammable processor; the stereo plug 17 is respectively used for Aux audio input and audio output; the toggle selection button 18 is used to select the output of the wooden box drum sound or the real-time music output. Of course, the sound effect processing method is not limited to the above-listed, and the sound effect buttons will also increase or decrease accordingly.
[0039] As Figure 3 shown, the electronic wooden box drum of the present invention further includes an external sensor connector 19, which can be externally connected to other sensors, such as vibration sensors, infrared sensors, grip sensors, etc. to sense the performer, so as to be able to control the playback of the real-time music. Of course, the type of sensor is not limited to the above-listed.
[0040] AsFigure 3 As shown, in order to attract players (especially those who need music therapy) to participate in playing near the cajon, a self-rotating ornament 20 (preferably a kaleidoscope) is also built in. The barrel of the kaleidoscope is preferably an isosceles triangle with a first side length at one end and an isosceles triangle with a second side length at the other end. The first side length and the second side length can be the same or different; a plastic PC soft lens is pasted inside the barrel. At the opening of the first side length, it faces the pattern box of the kaleidoscope. Colorful fragments are placed inside the pattern box to increase the patterns produced by the kaleidoscope, and diodes can be connected, such as self-flashing red, green, and blue light-emitting diodes, to further increase the ornamental value of the patterns.
[0041] In addition, a reduction motor (not shown) is configured, preferably with an operating voltage of 3V - 12V and a slow motor with an axis rotating at 52 revolutions per minute.
[0042] The second embodiment of the present invention relates to a method of using the above-mentioned electronic cajon, as Figure 5 shown, including:
[0043] Step 501, turn on the sensor of the electronic cajon;
[0044] Step 502, when the distance of the player is sensed within the set range, the microprogrammable processor controls the audio sound processor to play real-time music through the sound amplifier and the resonance speaker;
[0045] Step 503, within the set range, control the change of the sound of the real-time music according to the distance of the player sensed from the cajon.
[0046] Specifically, turn on the ultrasonic sensor through the ultrasonic sensor switch button, or connect other sensors externally through the external sensor connector; taking the ultrasonic sensor as an example, when the distance of the player is sensed within the set range, preferably the player is 280 - 560mm away from the ultrasonic sensor, the microprogrammable processor controls the audio sound processor to play real-time music through the sound amplifier and the resonance speaker. Within the set range, if the player is sensed to be approaching, control the sound of the real-time music to become louder, and if the player is sensed to be moving away, control the sound of the real-time music to become smaller; the player can also adjust the buttons as needed to perform various different sound effects processing on the real-time music. When the distance of the player is not sensed within the set range, the microprogrammable processor controls to stop playing the real-time music.
[0047] The step division of the above various methods is only for clear description. When implemented, they can be combined into one step or some steps can be split into multiple steps. As long as the same logical relationship is included, it is within the protection scope of the present invention; adding insignificant modifications or introducing insignificant designs to the algorithm or process, but without changing the core design of the algorithm and process, is within the protection scope of the present invention.
[0048] It is not difficult to find that this embodiment is a method embodiment corresponding to the first embodiment, and this embodiment can be implemented in cooperation with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment. For the sake of reducing repetition, they will not be elaborated here. Correspondingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment.
[0049] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present invention, and in actual applications, various changes can be made to them in form and details without departing from the spirit and scope of the present invention.
