Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mouse controller suitable for use in, for example, an electronic wind instrument.
[0002]
[Prior art]
Conventionally, electronic wind instruments are equipped with a pressure sensor that detects the biting force with the breath pressure sensor at the mouthpiece (mouth), detects the player's breathing pressure and the biting force, and electronically detects the breath pressure detection signal. By controlling the volume of the sound of the wind instrument and changing the pitch or tone of the sound that is generated by the detection signal of the biting force, a performance expression can be added.
[0003]
FIG. 3 shows the structure of a lead sensor for an electronic wind instrument disclosed in Utility Model Registration Publication No. 2506719. The mouse controller described in this publication includes a lead sensor 1 for detecting a biting force attached to the lower surface of the mouthpiece 2 and a breath pressure sensor 3 for detecting a breath pressure blown into the mouthpiece 2. The detection signal detected by the breath pressure sensor 3 is input to the circuit board 5 mounted inside the tube body 4, and the musical sound that is the sound of the wind instrument on the circuit board 5 is made to correspond to the presence or absence of the detection signal of the breath pressure sensor 3. In addition to controlling the level of the detection signal of the breath pressure sensor 3, the level of the signal is controlled to control the volume of the sound emitted from the speaker 6, and to the biting force detected by the lead sensor 1. Correspondingly, the pitch of the sound is controlled, and a performance expression such as tremolo or vibrato can be added.
[0004]
[Problems to be solved by the invention]
The mouse controller shown in FIG. 3 has a disadvantage that the breath pressure sensor 3 and the lead sensor 1 are configured separately, which increases the number of parts and increases the cost. Moreover, the breath pressure sensor 3 is formed in a sealed container that communicates with the mouthpiece 2, and has a structure that cannot breathe out.
[0005]
Therefore, since the performer is different from the state in which he / she breathes like a normal wind instrument, there is also a drawback that it is difficult to perform.
An object of the present invention is an electronic musical instrument that can reduce the number of parts required for a sensor, can reduce the cost, and can blow out the air, so that the performance can be performed without changing from a general wind instrument. To provide a mouse controller.
[0006]
[Means for Solving the Problems]
In the present invention, an elastic valve that elastically closes the breath outlet is provided on the breath outlet side of the tubular mouthpiece, and the valve is bent and deformed in accordance with the amount of breath blow. A breath pressure sensor for transmitting an electric signal corresponding to the amount of bending deformation is attached and formed.
[0007]
Furthermore, the elastic sheet member which comprises an elastic valve is extended to the breath-inlet side of a mouthpiece, and a pressure-sensitive sensor is attached and formed in this extended part, and a mouse controller is comprised.
According to the configuration of the present invention, the breath blown into the mouthpiece is exhausted from the mouthpiece outlet side of the mouthpiece after the elastic valve is bent and deformed in accordance with the blow amount. Since the valve that is bent according to the amount of breath blown is attached to a sensor that transmits an electric signal corresponding to the amount of bending, the volume of the instrument sound is controlled using this electric signal. be able to.
[0008]
Furthermore, since the pressure-sensitive sensor is mounted on the mouth opening side of the mouthpiece, the force for biting the mouthpiece can be converted into an electric signal. By controlling, for example, the frequency or timbre of the instrument sound using this electrical signal, a performance expression equivalent to that of a normal instrument sound can be realized.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show an embodiment of a mouse controller according to the present invention. In the figure, 2 indicates a tubular mouthpiece. The mouthpiece 2 includes an air inlet 2A and an air outlet 2B, and an elastic valve 11 that elastically closes the air outlet 2B is provided on the air outlet 2B side. The elastic valve 11 can be configured by a resin sheet 12 having elasticity as shown in FIG.
[0010]
The resin sheet 12 is led out to the outer peripheral surface of the mouthpiece 2 through the slit 13 formed in the mouthpiece 2, and the derived end is brought into contact with the outer peripheral surface of the mouthpiece 2 near the blowing port 2 </ b> A. The elastic valve 11 is elastically supported by holding the resin sheet 12 in a cantilever structure while holding it to the outer peripheral surface of the mouthpiece 2. In this example, the holding piece 14 is attached to the mouthpiece 2 with a screw 15, and the resin sheet 12 is held down at the end of the holding piece 14.
[0011]
In this example, the resin sheet 12 is made of, for example, an ink layer formed of a pressure-sensitive material on the elastic piece 11 side and the opposite side of the resin sheet 12 disposed on the breath blowing port 2A side by, for example, silk screen printing. It is deposited as 16A and 16B. A strip electrode 17 is formed on the lower surfaces of the ink layers 16A and 16B, and the ink layers 16A and 16B are deposited in contact with the strip electrode 17. By measuring the resistance value between the strip electrodes 17, changes in the resistance values of the ink layers 16A and 16B can be known. A lead wire 18 is connected to the strip electrode 17, and the lead wire 18 is connected to the circuit of the musical instrument sound generator.
[0012]
According to the above-described configuration, when breath is blown from the blowing port 2A, the breath bends the elastic valve 11 by the bending amount corresponding to the blowing amount. In the example shown in FIG. 1, the ink layer 16 </ b> A is compressed and deformed in accordance with the bending amount, and the resistance value of the ink layer 16 </ b> A is controlled to be reduced by the compression deformation. This resistance change decreases in inverse proportion to the amount of breath blown, and by controlling the sound volume generated by the resistance change, the sound volume is increased when blowing hard and the volume decreases when blowing weakly. be able to.
[0013]
On the other hand, when the mouthpiece 2 on the blowing port 2A side is bitten, the ink layer 16B formed on the resin sheet 12 is given a biting force via the restraining piece 14, and the ink layer 16B changes in a direction in which the resistance value increases. By this resistance change, performance expression such as tremolo or vibrato can be added by controlling the generation frequency of the musical instrument sound slightly or controlling the timbre.
[0014]
Although only the mouthpiece 2 is shown in the embodiment shown in FIG. 1, it can be easily understood that the electronic wind instrument can be configured by connecting the mouthpiece 2 to a tubular body imitating a wind instrument. Like.
[0015]
【The invention's effect】
As described above, according to the present invention, the ink layers 16A and 16B are formed on the common resin sheet 12, and one ink layer 16A is used as a breath pressure sensor, and the pressure sensitivity for detecting the biting force of the other ink layer 16B is detected. Since the sensor is used, two sensors can be constituted by one resin sheet 12. As a result, the number of parts can be reduced and the structure can be simplified, so that cost reduction can be expected.
[0016]
Furthermore, in the present invention, when breath is blown, the breath is exhausted from the air outlet 2B, so that the sound of the electronic wind instrument can be controlled in the same manner as a normal wind instrument. As a result, there is an advantage that the electronic wind instrument can be played without getting stuffy.
