Description

  The present invention relates to a musical instrument, and more particularly to a musical instrument that can generate string vibrations from a main body of the instrument, and convert string vibrations into electrical signals to generate sound from a speaker.

As a plucked string instrument, an acoustic guitar generally referred to as a “raw guitar” is known. The guitar has a resonance hole formed in the body (body) that constitutes the instrument body, and by stroking the string, the vibration vibration sound of the string is resonated in the body. .
Since such a guitar is not accompanied by electrical amplification, for example, when performing in a wide space such as a concert hall, the tendency that the sound wave is attenuated and cannot be heard at a position far away from the stage becomes strong. In particular, when playing with other musical instruments, there is a problem that the sound of the guitar is drowned out because the relative volume is low. In this respect, the electric acoustic guitar is equipped with a dedicated pickup inside the body and has a function of electrically amplifying, so that the expected sound volume can be secured even in a concert hall or the like.

  However, although an electric acoustic guitar has a function of converting string vibration into an electric signal by a sensor such as a pickup, an amplifier and a speaker must be provided separately from the instrument main body, There is no sense of unity. In addition, there is a disadvantage that the necessary equipment must be carried in and out every time the performance place is moved, which is inconvenient.

Further, it is said that the timbre (spectrum formant) of a musical instrument such as a guitar has a very high correlation with the timbre or texture of the wood used. In other words, when the instrument body is made of wood and the sound of the instrument is produced through the speaker, it is said that the speaker's diaphragm is more woody than the paper or metal, making it easier to obtain the same timbre. Yes. Moreover, if the musical instrument and the wood of the speaker are the same, the timbre is further improved.
Therefore, when the instrument body is made of wood, at least the diaphragm of the speaker is made of wood, which is an element for obtaining a good timbre.

  By the way, Patent Document 1 discloses a configuration in which a speaker diaphragm is made of wood. In this document, the diaphragm for a cone speaker is formed of a thin wood plate, and thereby, the timbre is intended to be close to the timbre of a live musical instrument.

Japanese Patent Laid-Open No. 61-178386

  However, the speaker described in Patent Document 1 merely uses a thin wood plate as a diaphragm for tone adjustment, and is not a special consideration in the correlation with the body member quality of a musical instrument. Absent. In addition, no attempt has been made to ensure design integrity between the musical instrument and the speaker.

[Object of invention]
An object of the present invention is to provide a musical instrument that can achieve harmony or identity between the timbre of the instrument body and the timbre produced by the speaker, and can ensure design integrity between the instrument body and the required equipment. There is to do.
Another object of the present invention is to provide a musical instrument having the convenience that can easily cope with a change in performance place.

In order to achieve the above object, the present invention provides a musical instrument that generates a sound by vibrating a string.
A musical instrument main body formed of wood or wood material, a sensor that converts vibration of the string into an electric signal, an amplifier that amplifies the signal of the sensor, and a diaphragm formed of the same or the same material as the musical instrument main body It is configured to include a speaker including.

  In the present invention, it is preferable that the sensor, the amplifier, and the speaker are arranged in the region of the instrument body.

  Moreover, it is good to equip the said instrument main body with a battery.

  Musical instruments to which the present invention is applied include general instruments that produce sound by vibration of strings, and specifically include stringed instruments such as guitars, violins, violas, cellos, and contrabass, as well as hitting strings with a hammer. It includes an electric piano that converts it into an electrical signal with a pickup, amplifies it, and produces a loud sound through a speaker.

  As the material of the musical instrument body, it is preferable to use spruce, rosewood, American cedar, spruce, scented sardine etc. in the case of acoustic, and in the case of solid type, use maple, ash, alder (alder), etc. Good.

  According to the present invention, since the musical instrument body and the diaphragm of the speaker are made of the same wood or wood material, it is possible to obtain the same timbre. Further, according to the configuration in which the amplifier and the speaker are provided in the region of the instrument main body, it is possible to impart design integrity. Therefore, if the instrument body has a resonance means, the sound as a live musical instrument can be heard, and the sound from the speaker can be heard even if the relative distance between the player and the audience is long. It becomes possible to adapt to the performance conditions flexibly. In addition, in the case of the battery built-in type, it is possible to eliminate the need to carry electrical equipment by transporting only the musical instrument.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view according to an embodiment in which the present invention is applied to an electric acoustic guitar. In this figure, an electric acoustic guitar 10 includes a musical instrument main body 11 formed in a generally saddle shape when viewed from the front and having a hollow inside, and a neck 12 extending upward from the upper part of the musical instrument main body 11 in FIG. The basic structure includes a head 13 provided at one end (the upper end in FIG. 1) of the neck 12 and a string 15 stretched along the neck 12 between the head 13 and the instrument body 11. .

  The musical instrument main body 11 is provided in a known shape in which a resonance hole 17 constituting a resonance means is formed at a substantially central portion in the surface of the sound plate 16 appearing in front in FIG. Further, in the region of the sound plate 16, a bridge 20 that fixes one end of the string 15, and the bridge 20 is provided between the string 15 and the sound plate 16, and vibration of the string 15 is electrically generated. A pickup 21 that constitutes a sensor for converting a signal, an amplifier 22 that amplifies an electrical signal of the pickup 21, and a speaker that vibrates using the output of the amplifier 22 as an input. 24 and a battery 25 that is mounted inside the musical instrument main body 11 and is electrically connected to the pickup 21, the amplifier 22 and the like.

  In the present embodiment, wood such as spruce, rosewood, American cedar, spruce, scented hiba etc. is used as the material of the musical instrument main body 11, and the diaphragm 24 A of the speaker 24 is the same wood as the musical instrument main body 11. Is used.

  The arrangement of the speaker 24 is not particularly limited, but in the present embodiment, it is arranged on the lower left side in FIG. This arrangement is determined in relation to these arrangements when various switches are attached in the area of the sound plate 16.

  In the above configuration, by playing the nail of the string 15, a sound can be generated through the resonance hole 17 as a normal acoustic guitar. On the other hand, when the power is turned on, the sound is produced from the speaker 24 together with the sound produced by the resonance hole 17 and can be used as an electric acoustic guitar. At this time, since the diaphragm 24A of the speaker 24 is the same as the wood used for the musical instrument main body 11, substantially the same timbre, that is, a sound that is the same as or close to the original sound of the acoustic guitar can be obtained.

The best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
