Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting mechanism for an electronic percussion sensor, particularly an electronic percussion sensor suitable for being installed in a keyboard or the like.

[0002]

[Prior Art]

 Electronic drums are well known, but in the case of conventional electronic drums, they are strongly hit with a stick, so sensitivity is not very good, and some external vibration is not emitted, so the instrument body, sensor No special measures are required for the structure of the parts.

However, when incorporated into other musical instruments such as a keyboard, particularly in the case of an electronic Taisho koto, it is not practical unless the sensor sensitivity is very good in order to produce sound with a force such as tapping with a fingertip. .. However, a sensor having a good sensor sensitivity has a problem that even if the sensor portion is not hit, vibration of another sounding body or external vibration applied to the main body of the musical instrument is picked up to vibrate and sound.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and its problem is to cut off external vibration applied to the part other than the sensor part and sense and signal it only when the sensor part is directly hit. It is to be able to extract as input.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms a penetrating mounting hole 2 in a mounting base 1 and arranges a pad 3 for hitting with a fingertip in the mounting hole 2 so that a pad edge 4 of the mounting hole 2 and a pad 4 are provided. A buffer body 5 is interposed between the pad 3 and the pad 3, and a sensor holder 6 which contacts the back side of the pad 3 and fixes the pad 3 at the mounting position is arranged on the back side of the mounting base 1 and overlaps with the pad 3. The sensor holder 6 is mounted with a sensor 7 for detecting a vibration applied to the pad 3 and emitting an output signal, and further, the sensor holder 6 is fixed to the back side of the mounting base 1 through an insulator 8 for blocking external vibration. The means to do so was taken.

[0006]

【Example】

 A description will be given below with reference to the drawings. The embodiment is an example in which the electronic percussion instrument sensor according to the present invention is attached to the upper surface of a main body 10 of an electronic Taisho koto which is an electronic version of the Taisho koto, and the main body 10 is made of wood (the material of the main body is not limited to wood).

As shown in FIG. 2, the mounting base 1 is composed of a decorative plate 11 on the surface of the main body and a structure 12 that bears strength, and a plurality of penetrating mounting holes 2 are formed in the sensor mounting portion. ing. Reference numeral 14 indicates an enlarged hole.

The pad 3 is arranged in the mounting hole 2, and the upper surface of the pad slightly protrudes from the upper surface of the main body. The pad 3 is provided with a flange 13 on the outer periphery of the inner end portion, and is mounted between the hole edge 4 of the mounting hole 2 and the flange 13 in such a manner that a cushioning body 5 for vibration isolation is sandwiched. At that time, a small gap 15 is provided between the mounting hole 2 and the pad 3.

The sensor holder 6 is attached to the back side of the attachment base 1 so as to support the pad 3 in the above-mentioned state and to transmit the vibration from the pad 3 to the sensor 7. The sensor 7 is installed in a portion of the sensor holder 6 that overlaps the pad 3 in position. The sensors 7 are provided at the respective portions of the plurality of mounting holes 2 so as to generate different timbres, for example, pads 3A and 3B shown in FIG. 1 generate large and small drums, and pads 3C and 3D generate timbres. To

The sensor 7 has a lead wire 16 that senses a tapping vibration applied to the pad 3 with a fingertip and sends an output signal to a sound source device built in the musical instrument body 10. A piezoelectric diaphragm can be used as such a sensor.

In order to mount the sensor holder 6 on the mounting base 1, an insulator that blocks external vibration is interposed. The insulator 8 includes a cushion material 8a made of a flexible material which is sandwiched between the mounting piece 17 of the sensor holder 6 and the structure 12 of the mounting base 1, and a fastener such as a screw for fixing the sensor holder 6 to the mounting base 1. 9 and a stop hole portion of the sensor holder 6 and a soft washer 8b interposed therebetween.

Further, the soft washer 8b has a double flange 8c formed so as to sandwich the retaining hole of the sensor holder 6, and a sleeve 8d through which the stopper 9 is passed and which is in contact with the structure 12, and each exerts a vibration damping action. To do. The material and structure of the cushion material 8a, the soft washer 8b, the cushioning body 5 and the like are selected according to the vibration characteristics applied to themselves, the main body 1 and the pad 3.

Regarding the main body 10 of the electronic Taisho koto, 20 is a keyboard part consisting of a white key 21 and a black key 22, 23 is a string sensor provided on the right hand side, and 24 is an operation button part provided on the left hand side of the keyboard part 20. There are a keyboard button 25 for selecting keyboard operation, a string button 26 for selecting string mode operation, a group of tone designating buttons 27 for designating the tone colors of Taisho Koto and other mainly Japanese musical instruments. By pushing, the sensor 7 is activated. In addition, 29 shows a volume knob.

Therefore, by turning on a switch (not shown), pressing the percussion instrument button 28, and striking any one of the plurality of pads 3 with a fingertip, a percussion instrument having a tone color corresponding to the pad 3 (A to D) can be obtained with headphones or You can make it sound from the speaker. That is, the impact applied to the pad 3 is sensed by the sensor 7 arranged under the pad 3 and processed by the musical tone.

In the case of the specific pad 3A, the impact applied to 3A is transmitted only to the sensor 7 of the pad 3A without being transmitted to the surroundings due to the buffer 5 and the insulator 8, and to the other pads 3B ... I don't get it. Further, even if external vibration is applied to the main body 1, the buffer 5 blocks the transmission of vibration in the relationship between the main body 1 and the pad 3, and the insulator 8 blocks the transmission of vibration in the relationship between the main body 1 and the sensor holder 6. To do.

[0016]

[Effect of the device]

 Since the present invention is constructed and operates as described above, it is possible to sense it as an input only when a direct impact is applied to the sensor 7, and on the other hand, external vibration applied to other than the sensor part. Alternatively, when there are multiple pairs of pads and sensors, vibrations applied to other than the pads and sensors being performed are reliably cut off, so there is no chance of picking up noise and causing malfunction. Therefore, it is suitable for adding a percussion instrument function to a keyboard such as an electronic Taisho koto, and has a practically remarkable effect.
