Description

Technical Field

[0001] This application relates to the field of musical instrument technology, and in particular to an electric wind instrument. Background Technology

[0002] An electric wind instrument is an electronic musical instrument. For a performer, the quality of an electric wind instrument mainly depends on two aspects: the effectiveness and functionality of the sound synthesis circuit, and the accuracy and speed of the detection of the performer's operation.

[0003] The main development direction of electronic wind instruments is currently focused on improving the sound synthesis circuitry, while there have been few changes to the human-computer interface for performers. Some electronic wind instruments have added a bite sensor to the mouthpiece to detect the performer's lip movements; others have replaced mechanical buttons with touch buttons, thereby increasing the sensitivity of finger movement detection.

[0004] However, these improvements do not bring about new changes in playing techniques for performers; in other words, the existing electric wind instruments allow for relatively limited playing operations. Summary of the Invention

[0005] Therefore, it is necessary to provide an electric wind instrument that addresses the aforementioned technical issues, offering more ways to enrich playing techniques and thus achieve more forms of expression.

[0006] An electric blowpipe includes: a mouthpiece, a tube body, and a first hand handle;

[0007] The mouthpiece is fixedly connected to the tube body; a sensing component is provided inside the mouthpiece, and a processing component is provided inside the tube body; the sensing component and the processing component are electrically connected.

[0008] The first hand handle is disposed on the tube body, and the first hand handle is provided with several buttons. The first hand handle has several strokes relative to the tube body, and the strokes are collected by the processing component.

[0009] In one embodiment, it further includes: a second hand handle; the second hand handle is fixedly connected to the tube body.

[0010] In one embodiment, it further includes: a second hand handle; both the first hand handle and the second hand handle are rotatably or slidably connected to the tube body.

[0011] In one embodiment, the processing component includes: a data acquisition unit;

[0012] The acquisition unit acquires the travel distance of the first handgrip, or simultaneously acquires the travel distance of the first handgrip and the second handgrip.

[0013] In one embodiment, the acquisition unit is a potentiometer; the first hand handle and the second hand handle are respectively fixedly connected to a potentiometer.

[0014] In one embodiment, the acquisition unit is a rotary encoder; the first hand handle and the second hand handle are respectively fixedly connected to a rotary encoder.

[0015] In one embodiment, the acquisition unit is a sensor; the first hand handle and the second hand handle are respectively fixedly connected to a sensor.

[0016] In one embodiment, the processing component further includes: an analog-to-digital converter, a storage unit, and a computing unit;

[0017] The analog-to-digital converter is electrically connected to the acquisition unit, and the computing unit is also electrically connected to the sensing component, the button, the analog-to-digital converter, and the storage unit.

[0018] The aforementioned electronic wind instrument features a novel structure. Based on existing electronic wind instruments, it incorporates a first handhold that is movably connected to the instrument body, with buttons located on this handhold. This allows the processing component to simultaneously acquire airflow parameters from the player's mouth and finger movements, as well as hand gestures (including the angle and speed of the first handhold). This information is then used as input to the sound synthesis circuit. Consequently, the sound synthesis operation can be further enriched based on hand gestures, enabling performance techniques and effects that are impossible with existing electronic wind instruments, thus providing users with more possibilities and more expressive performances.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Furthermore, the use of terms such as "first," "second," etc., in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this application, "multiple sets" means at least two sets, such as two sets, three sets, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.

[0036] This application provides an electric blowpipe, which in one embodiment includes: a mouthpiece 101, a tube body 106, and a first hand handle; the mouthpiece 101 is fixedly connected to the tube body 106; a sensing component is provided inside the mouthpiece 101, and a processing component is provided inside the tube body 106, the sensing component and the processing component being electrically connected; the first hand handle is disposed on the tube body 106, and the first hand handle is provided with several buttons, the first hand handle has several strokes relative to the tube body 106, and the strokes are collected by the processing component.

[0037] In this embodiment, the methods of fixing the mouthpiece 101 to the tube body 106, the mouthpiece 101 to the sensing component, and the tube body 106 to the processing component are all existing technologies and will not be described in detail here.

[0038] The sensing components include pressure sensor 102, etc., and the processing components include computing unit (circuit board 103, e.g., sound synthesis circuit) and acquisition unit (e.g., potentiometer 104), etc.

[0039] The first handpiece is movably connected to the tube body (the specific movable connection can be a rotational connection or a sliding connection, etc.). Therefore, the first handpiece has a travel relative to the tube body. Different travel distances correspond to different positions and different needs. This travel distance is collected by the processing component and synthesized into a sound signal. For example, if the performer rotates the handpiece, the processing component can detect the changed travel distance. Therefore, it can determine that the performer may want to change the frequency of the current audio signal. Then, a modulation algorithm can be used to process the audio signal to produce a vibrato effect.

[0040] During performance, the performer blows air from their mouth into the mouthpiece. Sensors within the mouthpiece detect relevant parameters of the airflow (e.g., pressure) and couple these parameters to the processing component. Simultaneously, different numbers and positions of buttons detect the performer's finger movements and couple this information to the processing component. The processing component, based on the input airflow parameters and finger movements, and combined with the collected travel distance of the first handgrip, generates corresponding audio electrical signals. These signals are then converted into sound signals perceptible to the human ear via a specific conversion device (e.g., headphones, speakers). Alternatively, the processing component, based on the input airflow parameters and finger movements, and combined with the collected travel distance of the first handgrip, generates standard MIDI information and transmits it to another device (e.g., a standalone audio synthesizer) via a communication connection (e.g., USB, Bluetooth). This device can then parse the MIDI information to achieve the corresponding function. Alternatively, the processing component may include both of these functions simultaneously.

[0041] The aforementioned electronic wind instrument, based on existing electronic wind instruments, incorporates a first handhold that is movably connected to the instrument body. The buttons are located on this first handhold, allowing the processing component to simultaneously acquire the performer's lip airflow parameters and finger movement information, as well as hand movements (including the angle and speed of the first handhold). This information is then used as input to the sound synthesis circuit. Therefore, the sound synthesis operation can be further enriched based on hand movements, enabling performance techniques and effects that are impossible with existing electronic wind instruments, providing users with more possibilities and more expressive performances. Furthermore, the process of acquiring hand movements in this application is continuous, seamless, and highly coherent.

[0042] like Figures 1 to 2 As shown, in one embodiment, it further includes: a second hand handle; both the first hand handle and the second hand handle are rotatably or slidably connected to the tube body.

[0043] In this embodiment, the mouthpiece has a plastic outer shell and a built-in pressure sensor.

[0044] The electric wind instrument has two movable handles on its body, namely the first handle and the second handle, each fixed to the shaft of a potentiometer. Both potentiometers are mounted on a circuit board. When the handles rotate or slide relative to the body, they drive the shafts of the potentiometers to rotate, changing the resistance of the potentiometers. This allows the processing component to collect the linkage information between the two handles.

[0045] It should be noted that the relationship between the linkage information between the two hand grips (including: the hand gestures, the relative positions of the two hands, the angle between the two hand grips, the speed of movement of the two hand grips, the direction of movement of the two hand grips, etc.) and the desired effect or MIDI information can be set according to the specific situation of the user. In actual use, the performer can select one of many effects in advance as the effect to be achieved by rotating the hand grips. The processing component will perform different processing according to the user's selection, such as distortion, overdrive, modulation, reverb, etc.

[0046] In one embodiment, it further includes: a second handle; the second handle is fixedly connected to the tube body.

[0047] In this embodiment, the tube body of the electric blowpipe is provided with a first hand handle that is movably connected and a second hand handle that is fixedly connected.

[0048] The first hand handle can be rotatably connected to the tube body, specifically as follows: Figure 3 As shown; the first hand handle can also be slidably connected to the tube body, specifically as follows: Figure 4 and Figure 5 As shown.

[0049] During performance, the performer blows air from their mouth into the mouthpiece while simultaneously operating different numbers and positions of keys with their fingers, and also rotates or slides the first hand handle. The processing component collects the above information and synthesizes the sound signal.

[0050] In one embodiment, the processing component includes: a data acquisition unit; when the tube body has only a first hand handle, or the tube body has a first hand handle and a fixedly connected second hand handle, the data acquisition unit acquires the stroke of the first hand handle; when the tube body has a first hand handle and a movably connected second hand handle, the data acquisition unit acquires the stroke of both the first and second hand handles simultaneously. Specifically, the data acquisition unit can be a potentiometer, rotary encoder, sensor, etc., and the number of data acquisition units corresponds one-to-one with the number of movable hand handles (using a movably connected first or second hand handle) to separately acquire signals from different movable hand handles.

[0051] In one embodiment, both the first and second hand handles are rotatably connected to the tube body and are respectively fixedly connected to the shaft of a rotary potentiometer. When the performer rotates the hand handles, the shaft of the rotary potentiometer generates a changing resistance value due to the linkage, which is collected by the rotary potentiometer.

[0052] In one embodiment, both the first and second hand handles are rotatably connected to the tube body and are fixedly connected to the shaft of a carbon brush rotary encoder. When the performer rotates the hand handles, the shaft of the carbon brush rotary encoder generates a change in angular displacement or angular velocity due to the linkage, which is collected by the carbon brush rotary encoder.

[0053] In one embodiment, both the first and second hand handles are rotatably connected to the tube body, and a grating rotary encoder is provided below the connection position. When the performer rotates the hand handle, the grating rotary encoder generates a changing angular displacement or angular velocity due to the change in the light signal, which is then collected by the grating rotary encoder.

[0054] In one embodiment, both the first and second hand handles are slidably connected to the tube body and are respectively fixedly connected to the shaft of a sliding potentiometer. When the performer slides the hand handles, the shaft of the sliding potentiometer undergoes a change in displacement due to linkage, which is collected by the sliding potentiometer.

[0055] In one embodiment, both the first and second hand handles are rotatably connected to the tube body and are respectively fixedly connected to the shaft of an angle sensor. When the performer rotates the hand handles, the shaft of the angle sensor changes angle due to the linkage and is collected by the angle sensor.

[0056] In one embodiment, both the first and second hand handles are rotatably connected to the tube body and are fixedly connected to a magnet. When the performer rotates the hand handles, the magnets change angle due to the linkage, and this angle is collected by a magnetic sensor located below the magnets.

[0057] In one embodiment, both the first and second hand handles are slidably connected to the tube body, and a photoelectric sensor is provided below the connection position. When the performer slides the hand handle, the photoelectric sensor generates a changing electrical signal due to the displacement of the light signal, which is then collected by the photoelectric sensor.

[0058] like Figure 6 The potentiometer's value reading circuit is shown. The potentiometer's center tap is connected to an analog-to-digital converter inside the processing unit. When the potentiometer is rotated, the voltage at the center tap changes, and this value is converted into a digital signal by the analog-to-digital converter.

[0059] like Figure 7 The encoder's numerical reading circuit is shown. The encoder's two output pins are connected to the digital signal input pins of the computing unit. When the encoder is rotated, a pulsating signal is generated on the pins. This pulsating signal can be sensed by the computing unit's digital signal input circuit and converted into a digital signal.

[0060] like Figure 8The diagram shows the internal layout of a handheld device (first handheld device and / or second handheld device). The internal circuit board of the handheld device has several buttons 107 (mechanical or touch-sensitive) and a first socket 108. The first socket 108 has a first plug. The internal circuit board (i.e., the computing unit) has a second socket 109, which has a second plug. The first plug and the second plug are connected by a flexible flat cable passing through the handheld device's outer shell. When a button 107 of the handheld device is pressed, the computing unit detects the operation and generates corresponding feedback to the sound synthesis circuit.

[0061] It should be noted that the handgrip 105 (first handgrip and / or second handgrip) can be connected to a rotary potentiometer, carbon brush rotary encoder, grating rotary encoder, angle sensor, or magnet via gear 110. This allows the rotary potentiometer, carbon brush rotary encoder, grating rotary encoder, angle sensor, or magnet to produce finer or faster parameter changes when the player rotates the handgrip. Figure 9 As shown.

[0062] like Figure 10 As shown, in one embodiment, the processing component further includes an analog-to-digital converter, a storage unit, and a computing unit; the analog-to-digital converter is electrically connected to the acquisition unit, and the computing unit is electrically connected to the sensing component, the button, the analog-to-digital converter, and the storage unit.

[0063] The processing component collects airflow information from the mouth through sensing components (such as pressure sensor values), collects finger movement information through button states, and collects hand movement information through a data acquisition unit. The hand movement information is converted into digital signals by an analog-to-digital converter. The calculation unit calculates and synthesizes the current sound information (audio electrical signal or standard MIDI information) based on the input pressure sensor values, button states, and digital signals. The storage unit stores instruction codes and data that can be read by the calculation unit.

[0064] There are many methods for synthesizing sound. For example, wavetable synthesis uses a computational unit to determine the output volume based on the pressure sensor readings and the output pitch based on the button status information. This allows the unit to select the corresponding data from the stored wavetable data and use that data as the output audio signal.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
