Description

Blowing electronic instrument {BLOWING ELECTRONIC INSTRUMENT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blowing electronic musical instrument, and more particularly, to detect flow rate, flow rate, acceleration, humidity, and the like of at least one of a plurality of sensors that blow into the mouth or inhale air. And an electronic musical instrument of a blowable type configured to determine an attribute of a sound of a pitch assigned to the sensor.

In general, electronic musical instruments are composed of electronic circuits such as sensors, amplifiers, filters, etc. that receive input values for sound generation from a keyboard or guitar string and convert them into electric signals. At present, electronic instruments corresponding to almost all musical instruments have emerged.

For most musical instruments, hand gestures are essential. Almost all instruments, including piano, violin, guitar, harp, gayageum, cymbals, xylophone and drums, are played by hand. And even wind instruments such as trumpets, saxophones, trumpets and flute, piccolo, ocarina, and wind instruments, such as bagpipes, use the airflow as the mechanism for generating the sound, and the adjustment of the pitch is by hand movement. Therefore, hand gestures are also essential for their corresponding electronic instruments.

On the other hand, harmonicas and pan flutes are examples of the musical instruments that can be played only by mouth. Of course, in the case of harmonica, there is an advanced method of wrapping and playing with hands, but basically, if the instrument is fixed, it can be played without a hand gesture. Also, touch the lips widely to pronounce the holes of various pitches at once, or pinch the lips to pronounce only the holes of a certain pitch, or use your tongue to rapidly exhale or inhale to produce distorted sounds. There are also various ways to play. In addition, the pan flute is generally a hand movement of the instrument, but can be played if the instrument is fixed.

For reference, the harmonica and the pan flute are limited to the scales determined at the time of manufacture. For example, the C major harmonica can play only the C major. To this end, the C major harmonica is composed of roads, les, beauty, waves, soles, las, cities, and roads. As another example, the D major harmonica can play only the D major. To this end, D major harmonica consists of les, me, par # s, sol, la, poetry, do #, and les. In this way, a harmonica is produced and used for each major and each minor. The same is true for pan flutes.

However, there is also a chromatic harmonica that can play all 12 chromatic scales with a knob that can raise or lower the semitone, and the semitone knob is provided to be operated by hand. By the way, such a chromatic harmonica is mainly used for a performance, and it is difficult for the general public to use the song which generally produces transposition.

Conventionally, as described in the patent document, 'a blowing body which is configured similarly to a harmonica and can be played similarly, is arranged in the blowing body and responds to a human blowing or intake air flow, and responds to a position where such air flow occurs. A response device for controlling a synthesizer as a response function, a replaceable blower installed in the blower body and movable along a predetermined movement passage, the blower having a single blower and a suction hole, and a response device having a static pressure converter; A response device equipped with a blower and an intake port communicating with a static pressure transducer, a position sensor installed in a row along a movement path of the blower port, a part which can be replaced with the blower port, and a function together with the part A position sensor, an evaluation circuit, said constant pressure transducer and a position sensor connected to said evaluation circuit, and said positive pressure Ventilation and as a response function of the position detector in an electronic instrument operating device with one or more of synthesizer, characterized in that the evaluation circuit is configured to generate the control voltage for the synthesizer, is disclosed.

Since it should be, there is a problem that the volume of the electronic instrument is increased, the power consumption is increased and the manufacturing cost is increased.

In addition, the technique of the patent document can produce a semitone by pressing the button 36, like the chromatic harmonica, but the hand has to be used to press the button, so the hand is not free.

Moreover, the technique of the said patent document is equipped with the threshold detector, and it is output so that a pressure measuring instrument may detect the airflow more than a certain intensity, and the output of the extremely small sound like the breath sound which is essential for realism and emotion transmission in an instrument There is a problem that is impossible.

<Basic Configuration>

Blowing electronic musical instrument 10 according to an embodiment of the present invention, the sensor set (s) , the AD converter 16 , the tone reference unit 14 , the signal generator 15 , the signal And an output unit 17 .

The sensor set s is a sensor array including a plurality of sensors s1 to snn for detecting a flow rate and a flow rate of an inhalation or inhalation inhalation.

Each sensor constituting the plurality of sensors s1 to sn is basically composed of a flow rate sensor. Details of the flow rate sensor are clear by the known art, and thus a detailed description thereof will be omitted. However, if the flow rate sensor is a small sensor that detects the amount of flow of the fluid, the present invention is not particularly limited.

However, each sensor constituting the plurality of sensors s1 to snn of the present invention does not merely detect a flow rate, but particularly has a function of detecting or calculating the speed of the flow of inhalation or intake air. The speed of the flow is known as the flow rate per unit time and can be calculated by detection by a dedicated sensor or by a combination of a flow sensor and a timer.

The plurality of sensors are physically arranged in an array. In addition, a unique pitch is assigned to each sensor. And all the sensors can work together at one time. Thus, if flow rates and flow rates are detected at a plurality of sensors at one time, output is made for these plurality of sensors. For example, if flow rates and flow rates are detected at three sensors, then output is made for these three sensors.

The AD converter 16 is a member that digitizes detection data from the sensors s1 to sn in which a flow rate and a flow rate of the sensor set s are detected. That is, instead of digitizing all the sensors, the digitization is performed only for the sensors s1 to sn where both the flow rate and the flow rate are detected. As a result, processing speed can be improved and power consumption can be reduced.

The tone reference unit 14 is a unit for determining data of the tone of the output sound. The tone is an attribute of sound unique to each instrument, such as a harmonica tone, a piano tone, a violin tone, and the like. However, the timbre in the present invention is not limited to the sound of the musical instrument, and may further include various timbres, such as a dog building sound, a human humming sound, and a wind sound. The data of the timbre is specified before the output of the sound.

Only one piece of data of the timbre may be specified in the electronic musical instrument of the present invention. In this case, the electronic musical instrument of the present invention outputs sound only in the designated timbre.

On the other hand, a plurality of data of the tone may be stored in advance in the electronic musical instrument of the present invention. In this case, the output sound can be output in a tone selected from the data of these plural tones. The tone selected is not limited to one. If a plurality of tones are selected, the plurality of tones may be combined to output an output sound. In this way, sounds of the same pitch are output together in plural tones, thereby producing the same effect as several musical instruments being played at the same pitch at the same time. In order to select data of the timbre, an input unit to be described later may be provided.

The signal generator 15 determines data of at least pitch and volume of the output sound from the data from the AD converter 16, receives data of the timbre from the timbre reference unit 14, and the pitch and volume. And a unit for generating a signal of the output sound by combining the timbres.

The air flow of the exhalation or intake air passing through the sensor set (s) generates flow and flow rate data as an electrical signal to one or more sensors, which are digitized by the AD converter, from which the pitch and volume of the output sound can be determined. . Since the pitch is data predetermined for each sensor s1 to sn, the pitch of the sensor from which the flow rate and the flow rate are detected is uniquely determined. The volume of the output sound of the pitch can be determined based on the flow rate and the flow rate. The larger the flow rate, the higher the volume signal, and the faster the flow rate, the volume signal may be shaped to soar rapidly.

The data of the timbre may be designated as one timbre, but as mentioned above, the timbre may be designated as two or more timbres, in which case the effect of harmony or translation by two or more instruments may occur. have.

When the tone data is combined with the pitch and volume information, the sound of the designated pitch is shaped into the sound of the tone specified by the calculated volume, thereby forming a waveform of the output tone, for example.

The signal output section 17 is a unit that outputs a signal of the output sound. The output of the signal can be of various forms and routes. For example, the output signal may be output in the form of sound waves into the air through an output device such as a loudspeaker in the form of sound. Alternatively, the output signal may be stored in, for example, magnetic tape in the form of analog data, or stored in a temporary or permanent memory of a terminal, such as a smartphone, tablet, or PC, which is an information and communication device in the form of digital data, for example, a composition program. It may also be used by apps such as.

<Effect>

According to the above configuration, the sensor set s composed of a plurality of sensors s1 to sn is provided, and the plurality of sensors s1 to sn are operated at the same time. It will be output along with the surrounding pitches to become a chord.

In addition, since the plurality of sensors s1 to sn are provided so that their positions are not moved, a movement path is unnecessary for the input of airflow, and a configuration of a position sensor for detecting the moved position is unnecessary.

In addition, hand gestures are required only for settings other than performance, such as shift of a scale, tone change, output change, and the like, which are described later.

In addition, it is possible to output the sound corresponding to the airflow of all the intensity sensed by each sensor (s1 ~ sn) of the sensor set, thereby improving the sense of presence and emotional transmission difficult to express in electronic instruments such as breath sounds or ambient noise There is.

<Tone database>

On the other hand, the instrument 10 may be composed of voice database 13 in which voice data of the output sound is stored is further included. The data of the tones include not only tones of various musical instruments but also tones of various effect sounds such as animal sounds, natural sounds, and automobile sounds. The data of the timbre is combined with the pitch and volume data and used to synthesize the output sound. Data in the tone database 13 may be generated, changed, or deleted from a server not shown through wired or wireless communication, or through a terminal 20 connected to the instrument 10 by wire or wireless.

In this case, the tone reference unit 14 receives the tone data from the tone database 13 of the terminal 20 connected to the tone database 13 or the instrument 10 in a wired or wireless manner by a predetermined tone designation command . It may be configured for reference. Here, the terminal 20 means an information processing device, and includes, for example, a smartphone, a tablet PC, or a PC.

<Input section>

The instrument 10 may further include an input unit 11 for inputting a set value. The set value may include designation of a timbre, designation of a pitch, designation of an output, and the like. The input unit 11 may include at least one of a button, a key, a touch panel, a touch screen, and the like, and may include, for example, a pointing device for selecting an item from a list displayed on a display as an unshown output unit.

The set value by the input from the input unit 11 is used by the control unit 12 to control the operation of the tone reference unit 14, the signal generator 15, or the signal output unit 17.

<Specify Voice>

When the input unit 11 is provided, the timbre referenced by the timbre reference unit 14 is inputted from the input unit 21 of the terminal 20 connected to the input unit 11 or the instrument 10 by wire or wireless. It may be configured to be configured to be selected by a predetermined tone designation command . Thus, it is possible to change the timbre of the musical instrument 10 of the present invention to various timbres.

<Specify pitch>

When the input unit 11 is provided, the pitch designated for each sensor s1 to sn of the sensor set s is connected to the input unit 11 or the instrument 10 by wire or wireless connection. The input unit 21 may be configured to be shifted up or down by a predetermined pitch designation command . In other words, the pitch of only one specific sensor can be shifted, and the uniform pitch of all sensors can be shifted.

For example, the pitches of the plurality of sensors s1 to sn may be set to a preset tone, for example, a whole tone and a semitone forming a C major. According to this setting, it is convenient for playing a song formed by one scale (C major).

In this case, the sensor set s itself may be shifted upward or downward by the pitch assigned to each sensor s1 to sn in a state in which the sensor set s itself is physically fixed to the musical instrument 10. That is, it can shift so that it may become whole tone and semitone which collectively form D major, for example. According to this configuration, while playing a song formed by one scale (C major) can be moved to a song formed by another scale (D major) as a whole, an effect such as transposition using other capo can be easily achieved.

<Specify output>

And when the input unit 11 is provided, the signal output by the signal output unit 17,

(1) its own speaker 18 of the instrument 10 or

(2) a speaker 18 'connected to the instrument 10 in a wired or wireless manner or

(3) the own speaker 28 of the terminal 20 connected by wire or wireless to the musical instrument 10 or

(4) a speaker 28 'connected to a wired or wireless terminal 20 connected to the musical instrument 10 by wire or wireless.

Can be output as a sound signal. This allows you to hear output sounds from various speakers. Among these various speakers, two or more speakers may be output at the same time.

Alternatively, the signal output by the signal output unit 17,

(5) It may be output as a data signal to the app 29 of the terminal 20 connected to the instrument 10 by wire or wireless. The data signal may vary depending on the type of the app 29. For example, if the app 29 is a composition app, the data signal may be stored and utilized as note data.

The output destination or output form may be configured to be selected by a predetermined output designation command from the input unit 21 of the input unit 10 or the terminal 20 connected to the musical instrument 10 by wire or wireless. Therefore, the player of the musical instrument 10 or the operator of the terminal 20 can select and adjust the singular plural number, etc. with respect to various output forms.

<Effect effect according to acceleration and humidity>

On the other hand, the plurality of sensors (s1 ~ sn) is preferably to further detect the acceleration or humidity of the breath or intake.

Acceleration is a parameter that tells whether the speed of the air flow tends to be faster or slower. By this acceleration, it is possible to know whether the emotion that the player wants to express becomes intense or subsides. In order to detect the acceleration, a sensor function for detecting the acceleration may be added to the plurality of sensors s1 to sn, or an additional acceleration sensor is added to the plurality of sensors s1 to sn in succession. The acceleration may be calculated by calculation from the flow rate and velocity.

Humidity means the amount of water contained in the air stream, which may include water contained in air from the lungs contained in the air stream, and water by saliva. By this humidity, it is possible to know whether the player's feelings are dry and light or lonely and blessed. In order to detect the humidity, a sensor function for detecting humidity may be added to the plurality of sensors s1 to sn, or a separate humidity sensor is continuously added to the plurality of sensors s1 to sn. Also good.

In this case, the signal generator 15 is preferably configured to add an effect component to the output sound based on the acceleration or humidity. The effect component may include delay, echo, flanger, chorus, vibration, reverb, tremolo, distortion, overdrive, and the like.

For example, when the acceleration is large, the output sound may be shaped by combining tremolo, distortion, and overdrive in order to express the emotion. For example, in the case of low humidity, the output sound can be shaped by reducing the delay and increasing the chorus effect for light expression. By the addition of such an effect component, there is an effect that the expression of the player's emotion can be finely adjusted.
