Description

Technical Field

[0001] The present invention relates to an input device, and in particular to a human-machine sensing input device, a component and a system. Background Art

[0002] Different from traditional musical instruments, electro-acoustic instruments are emerging instruments that use electronic technology to serve music. In terms of the order of development of electro-acoustic instruments, they can be roughly divided into the following generations.

[0003] The first generation of electroacoustic instruments simply added amplifiers to the original traditional instruments. For example, at a concert, a microphone was placed on a traditional guitar, and the collected electrical signals were amplified and played on the venue's sound amplification equipment.

[0004] The second generation of electro-acoustic musical instruments uses a pickup to collect the weak output sound signal of the improved musical instrument and transmit it to the effector, which outputs the electrical signal after processing and then plays it through a power amplifier. Examples of the second generation of electro-acoustic musical instruments include electro-acoustic guitars, electro-acoustic erhu, etc.

[0005] The third generation of electro-acoustic instruments are completely electronic and information-based. A variety of sensors collect the characteristic behaviors of the user's performance, and convert them into parameters required for the synthesis of musical sounds (such as pitch, length, volume, timbre, etc.) through a processor. These parameters are then modulated by a musical sound synthesis processor to affect the output electrical signal played by the power amplifier. Examples of the third generation of electro-acoustic instruments include electronic keyboards, electronic drums, electronic wind instruments, etc.

[0006] Most electronic wind instruments use mouth-blown input, and mouth-sucked input is less common. Harmonicas and flutes are even rarer. Most wind instruments use airflow sensors. In addition, in order to avoid too many pins on the key switches, the force-free electronic keyboard uses a two-dimensional matrix scanning switch to reduce the number of flat cables. Force-based electronic keyboards add two-point (or three-point) sensing components to the force-free electronic keyboard to detect the speed (or acceleration) of the keys and convert them into force. However, in the past, in order to change the sound of force-free mouth-blown, mouth-sucked, harmonicas, flutes, etc., multiple input sensors had to be used at a time and were expensive. It took a very high cost to achieve good sensor sensitivity. Summary of the invention

[0007] Problems to be solved by the invention:

[0008] Among the third generation wind instruments, straight flutes are common, and most of them are mouth-blown, and mouth-sucked, less common. Harmonicas and transverse flutes are even rarer. Currently, most of the input sensors used by wind instruments are air flow sensors.

[0009] Most of the third generation string instruments collect the vibration signals of the strings through pressure sensors and convert them into digital signals. The present invention proposes a way to connect the vibration sensor and the pressure sensor in series to achieve this, making it a force-type string human-machine sensor input device. Or use a vibration sensor to make it a force-free string human-machine sensor input device.

[0010] The principle of the third generation of drum instruments is that the pressure sensor generates an electrical signal after the built-in trigger is struck. The present invention proposes a way to connect a vibration sensor and a pressure sensor in series to achieve this, making it a force-type drum human-machine sensor input device. Or use a vibration sensor to make it a force-free drum human-machine sensor input device.

[0011] In the development process of the third generation of keyboard instruments, the force-free electronic keyboard adopts a two-dimensional matrix scanning switch to reduce the number of flat cables in order to avoid too many pins of the key switch. The force-sensitive electronic keyboard adds two-point (or three-point) sensing components on the basis of the force-free electronic keyboard to detect the movement speed (or acceleration) of the keys and then convert it into the force. The present invention proposes to use a demultiplexer, a switching switch, and a sensor group to realize a force-sensitive keyboard-type human-machine sensing input device.

[0012] However, in the past, in order to change the sound of the forceless electronic piano, multiple input sensors had to be used at a time and were expensive, requiring extremely high costs to achieve good sensor sensitivity. The present invention proposes to achieve this by using a buzzer built into a specially designed airflow pipeline, which can be applied to wind instruments including straight flutes, harmonicas, and transverse flutes. Through the present invention, good sensor sensitivity can be achieved by using a low-cost buzzer.

[0013] Among keyboard instruments, compared with non-force-type electronic keyboards, force-type electronic keyboards can perform more diverse and perfect performances. The present invention proposes the use of a demultiplexer, a switching switch, and a sensor group, which can reduce the cost of setting up multiple expensive sensors on the one hand, and easily achieve force-type keyboard performance sounds on the other hand.

[0014] Means of solving the problem:

[0015] The present invention provides a human-machine sensor input device, component and system, which can be combined with an electronic musical instrument through a sensor to convert a musical sound signal.

[0016] The present invention proposes a human-machine sensor input device, comprising: a sensor, a shell covering the sensor, a substrate provided at the bottom of the shell, the substrate being used to position the sensor package, the shell having an opening above the corresponding sensor, so that the sensor can detect an input signal, convert it into an output signal and then output it; a processing module electrically connected to the sensor to receive the output signal from the sensor and convert the output signal into a musical audio signal.

[0017] Beneficial effects of the present invention:

[0018] In summary, the human-machine sensor input device of the present invention senses airflow or pressure through a sensor and outputs an output signal, and then the processing module receives the output signal and converts it into a musical sound signal.

Figure 1The human-machine sensor input device 1 includes: a sensor 11, a housing 12, a processing module 13 (shown in Fig.11 ). The human-machine sensor input device 1 covers the sensor 11 with the housing 12. A substrate 121 is provided at the bottom of the housing 12. The substrate 121 is used to package and position the sensor 11. The housing 12 has an opening 122 above the sensor 11, so that the sensor 11 can detect an input signal, convert it into an output signal and then output it; the processing module 13 is electrically connected to the sensor 11, receives the output signal from the sensor 11, and converts the output signal into a musical sound signal.

[0037] After receiving input signals such as gas flow and pressure, the sensor 11 of the present invention converts the input signals into output signals, and then outputs them to the processing module 13 .

[0038] In an embodiment of the present invention, the human-machine sensor input device 1 of the present invention may include a power source (omitted in the figure), and the power source may be, for example, a battery or an external power source, but is not limited thereto.

[0039] Figure 2 A schematic diagram showing a wind instrument human-machine sensor input assembly according to Embodiment 1 of the present invention. Figure 1 and Figure 2 The wind instrument human-machine sensor input assembly 2 comprises: a gas oscillation chamber 21, a human-machine sensor input device 1, a first conduit 22, and a second conduit 23. The gas oscillation chamber 21 comprises: a first air cavity 211, a second air cavity 212, and a baffle 213.

[0040] A baffle 213 is disposed in the gas oscillation chamber 21, and the baffle 213 separates the gas oscillation chamber 21 into a first gas cavity 211 and a second gas cavity 212, and the baffle 213 has at least one guide hole 2131, so that the first gas cavity 211 and the second gas cavity 212 are fluidically connected. The human-machine sensor input device 1 is disposed on the baffle.

[0041] The first air cavity 211 has a first air cavity guide opening 2111 on the upper side, and the second air cavity 212 has a second air cavity guide opening 2121 on the lower side. The first conduit 22 passes through the first air cavity guide opening 2111 so that a portion of the first conduit 22 is inside the first air cavity 211; the second conduit 23 passes through the second air cavity guide opening 2121 so that a portion of the second conduit 23 is inside the second air cavity 212.

[0042] Specifically, the first conduit 22 is the only air inlet of the gas oscillation chamber 21, and the second conduit 23 is the only air outlet of the gas oscillation chamber 21. When the user blows air to the portion of the first conduit 22 exposed outside the gas oscillation chamber 21 with his mouth to form an airflow, the airflow flows from the first conduit 22 to the first air cavity 211 and flows to the human-machine sensor input device 1 disposed on the baffle. The sensor 11 senses the flow of the airflow through the opening 122 of the housing 12 (illustrated by the dotted arrow) and receives the input signal. The airflow will flow to the second air cavity 212 through the guide hole 2131 of the baffle 213, and then the airflow will flow out from the second conduit 23.

The baffle 313 has at least one guide hole 3131, etc., so that the first gas cavity 311 and the second gas cavity 312 are fluidically connected. The human-machine sensor input device 1 is disposed on the baffle.

[0046] The first air cavity 311 has a first air cavity guide opening 3111 on the upper side, and the second air cavity 312 has a second air cavity guide opening 3121 on the lower side.

[0047] Specifically, the first conduit 32 is the only outlet of the gas oscillation chamber 31, and the second conduit 33 is the only inlet of the gas oscillation chamber 31. When the mouth inhales air from the part of the first conduit 32 exposed outside the gas oscillation chamber 31, an airflow will be formed, and the airflow will flow from the second conduit 33 to the second air cavity 312, so that the airflow will flow to the human-machine sensor input device 1 set on the baffle. The sensor 11 senses the flow of the airflow through the opening 122 of the housing 12 (illustrated by the dotted arrow) and receives the input signal. The airflow will flow to the first air cavity 311 through the guide hole 3131 of the baffle 313, and then flow out from the first conduit 32.
