[0001] The invention relates to the technical field of electric blowpipes, in particular to a control system for single-touch multi-control note keys of an electric blowpipe. Background Art

[0002] The electric blowpipe is a new type of wind instrument that uses electronic technology. It can simulate the timbre of many instruments. The electric blowpipe can not only simulate the timbre of traditional wind instruments, such as clarinet, oboe, trumpet, etc., but also other traditional instruments such as pipa, erhu, etc.

[0003] The fingering method of the existing electric blowpipe is basically the same as the traditional original fingering method of playing saxophone and bamboo flute. That is, when playing a certain note on the electric blowpipe, a group of note keys need to be pressed simultaneously with multiple fingers to play the note. Figure 5 As shown, by touching a group of keys with multiple fingers at the same time, a group of pronunciation units is triggered, and the triggered multiple pronunciation units are synthesized to produce the corresponding single note. This requires continuous and rapid thinking about the combination of fingers, which can easily cause brain fatigue; it requires high coordination of finger movements and reaction speed, which is prone to errors; it brings great obstacles to beginners and elderly players.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1: Figure 1 The control system of a single-touch multi-control note key of an electric blowpipe shown in the figure includes a power module for providing electric energy to the electric blowpipe; a key module, which is electrically connected to a main control module and performs corresponding key pressing instructions according to a user's pressing instructions; a main control module, which is electrically connected to a power module, which processes the pressing instructions and sends the processed instructions to a pronunciation module; and a pronunciation module, which is used to play note sounds and is electrically connected to the main control module.

[0028] See also Figure 2 and Figure 3 As shown, the key module is composed of multiple note keys, and the note keys are touch keys or mechanical keys. Each note key is connected to multiple notes, and a single note key is pressed. Figure 6 As shown, 1-7 trigger ends are gathered on the touch surface of each note key, and multiple ends are triggered simultaneously by touching the note key with a single finger, forming a multi-finger combination effect, and emitting multiple set notes through the pronunciation module.

[0029] In this embodiment, there are 7 note keys, each of which is provided with 7 wire connectors, and one or more of the wire connectors are connected to the corresponding wire connectors on the control module. The main control module mainly adopts a main control chip of model CD4051, which is a single-ended 8-channel digital control analog electronic switch. An integrated circuit chip that controls multiple on and off points to be turned on or off synchronously serves as a bridge control between the key module and the pronunciation module. The pronunciation module is a loudspeaker, and a pronunciation circuit board is provided inside the loudspeaker.

[0030] An electric blowpipe adopts the above control system.

[0031] See also Figure 2 The figure shows the use of a single-touch multi-control integrated circuit, using a single finger to touch a single touch end, and multiple points to act synchronously to achieve the effect of multi-finger combination. The circuit or integrated chip with this performance is used as a bridge control between the touch key and the pronunciation board, and the corresponding connection is determined according to the original trigger pronunciation combination relationship. The seven channels formed between the A end and each of the terminals from B1 to B7 are A-B1 channel, A-B2 channel, A-B3 channel, A-B4 channel, A-B5 channel, A-B6 channel, and A-B7 channel. The A end and each of the terminals from B1 to B7 are in a normally open state, and the terminals from B1 to B7 are not connected to each other. When the finger touches the touch point (the breakpoints of the A and C circuits are inductive touch switches), a conductive loop between the A end and each of the terminals from B1 to B7 is instantly formed and maintained; when the finger leaves without touching, each point instantly returns to a normally open state, and the terminals from B1 to B7 are not connected to each other.

[0032] See also Figure 3 As shown, this embodiment is a connection diagram of a single-touch multi-control integrated circuit and an existing circuit, with the note key on the right and the pronunciation module on the left. The specific pronunciation actions are as follows: note key M7: touching the M7 key can trigger K7; note key M6: touching the M6 ​​key can trigger K6-K7; note key M5: touching the M5 key can trigger K5-K7; note key M4: touching the M4 key can trigger K4-K7; note key M3: touching the M3 key can trigger K3-K7; note key M2: touching the M2 key can trigger K2-K7; note key M1: touching the M1 key can trigger K1-K7. By touching a single key, a corresponding group of units are triggered, and the corresponding pronunciation notes are synthesized through the pronunciation units.

[0033] Example 2: See Figure 1 As shown, a control system for a single-touch multi-control note key of an electric blowpipe includes a power module for providing electric energy to the electric blowpipe; a key module, which is electrically connected to an active module and performs corresponding key pressing instructions according to a user's pressing instruction; a main control module, which is electrically connected to the power module, processes the pressing instruction, and sends the processed instruction to a pronunciation module; and a pronunciation module, which is used to play note sounds and is electrically connected to the main control module.

[0034] See also Figure 1 and Figure 4As shown, this embodiment determines the corresponding connection according to the original trigger combination relationship, realizes one-finger touch, can trigger multiple trigger ends at the same time, and realizes the corresponding note is emitted by one key. The right side is the note key, and the left side is the pronunciation module. The specific pronunciation actions are as follows: Note key M7: touch the M7 key to trigger K7; Note key M6: touch the M6 ​​key to trigger K6-K7; Note key M5-K7: touch the M5 key to trigger K5-K7; Note key M4-K7: touch the M4 key-K7 to trigger K4-K7; Note key M3: touch the M3 key to trigger K3-K7; Note key M2: touch the M2 key to trigger K2-K7; Note key M1: touch the M1 key to trigger K1-K7. This embodiment is a circuit diagram of the connection between a single-touch multi-control key and an existing circuit. According to the original trigger combination relationship, the corresponding connection is determined to realize one-finger touch, can trigger multiple trigger ends at the same time, and realize the corresponding note is emitted by one key.

[0035] See also Figure 6 As shown in the figure, multiple (1-7) trigger terminals are integrated on the touch surface of a key. Single-finger touching the note key can achieve multi-terminal triggering at the same time, forming a multi-finger combination effect. The two figures on the left are detailed diagrams of single-touch multi-control keys. There are two specific distributions of multiple touch points integrated on a key surface. The upper figure is the distribution of dot-shaped touch points on a key surface, and the lower figure is the distribution of linear touch points on a key surface, both of which are to improve the synchronous contact with the finger surface. The figure on the right is the symbol for a single-touch multi-control key. All the symbols used in the figure indicate multiple touch points on a key surface, that is, a single-touch multi-control key.

[0036] See also Figure 7 As shown, the action states of the eight note keys are converted into digital instructions and sent to the instruction parsing module. Fig. 9 As shown, the received key instructions are converted into note instructions according to the instruction parsing table shown and sent to the main control module. The main control module determines the note source based on the note instruction and the sound source selection instruction, and sends it to the pronunciation module. The pronunciation module emits different notes of different instruments according to the note source instruction.

[0037] See also Figure 8 As shown, in the prior art, only by pressing all the keys K1-K7, the corresponding 7 instruction strings are generated to parse the note instructions. The pronunciation instruction table of the present invention is shown in FIG. Fig. 9 As shown, by pressing only K1, a command string of 1000000 is generated to parse out the note command of F1.

[0038] The mechanical keys in Example 1 and Example 2 are input methods through mechanical induction electric blowpipes, and the input is triggered by hand operation. The touch keys are input by capacitance recognition of human body or object touch, and the core is to recognize input content through the capacitive touch panel.

[0039] The present invention adopts a single finger touching a single note key, and realizes the effect of multi-finger combination through the cooperation of a control module and a pronunciation module and multi-point synchronous action.

[0040] The fingering of the electric blowpipe is simplified. Under the premise of keeping the original functions of the electric blowpipe basically unchanged, through the multiple pronunciation control of a single note key, a single key can emit multiple set notes when playing the electric blowpipe, making the playing of the electric blowpipe simple and easy to operate, and reducing the difficulty of playing the electric blowpipe.
