Description

  The present invention relates to a guitar that is not provided with a resonance drum so as not to emit loud sounds.

  In recent years, various guitars called so-called silent guitars are commercially available (see, for example, Patent Documents 1 and 2). This silent guitar is not provided with the resonance drum of a normal acoustic guitar. For this reason, even if a performer plays this guitar, only a very slight sound is generated from the guitar. In addition, in a conventional silent guitar, a pickup device that directly converts string vibration into an electric signal, an amplifier circuit that amplifies the electric signal output from the pickup device, and an electric signal output from the amplifier circuit Some are equipped with a headphone terminal for taking out the outside. By connecting headphones to the headphone jack and listening to the sound from the headphones, the performer can enjoy playing the guitar without hesitation even when practicing at night or when there is a family around.

  However, the sound that the performer hears through the headphones is an electrically processed sound that is similar to anyone who plays it, regardless of how the strings are played. That is, with the conventional silent guitar, the performer cannot hear the sound that faithfully reproduces the sound caused by the vibration of the strings. On the other hand, if the performer listens directly to the sound of string vibration without using headphones, the silent guitar is not provided with a resonance drum, so the sound is low and feels unsatisfactory. Therefore, it is desired to realize a silent guitar that allows a performer to hear a loud sound faithful to the vibration of a string without bothering people around him.

  The present invention has been made based on the above circumstances, and an object of the present invention is to provide a guitar in which only a performer can hear a loud sound faithful to the vibration of a string without making a loud sound around. Is.

In order to achieve the above object, the present invention provides a guitar that does not include a resonance body,

  Further, in the guitar according to the present invention, the main body portion has a length from the attachment position where the main body portion is attached to the back surface of the body portion to the upper end portion, and a direction from the attachment position toward the upper end portion and the length of the neck portion. It is desirable that the angle formed with the direction is adjustable. Thereby, the performer can adjust the length and angle of the main body to easily adjust the position of the ear pad to the position of his / her ear.

  Furthermore, in the guitar according to the present invention, it is desirable that the ear pad is configured so that the tilt angle in the front-rear direction of the performer and / or the tilt angle in the left-right direction of the performer can be adjusted. Thereby, the performer can adjust the angle of the ear pad part to ensure that the ear pad part is close to his / her ear during the performance.

  In the guitar according to the present invention, since the vibration of the string is transmitted directly to the performer's ear through the trunk and the vibration transmitting unit, the performer can play the string from low to high, unlike the sound heard through the headphones. A loud sound faithful to vibration can be heard. In addition, the guitar body does not have a resonance body, and the live sound that directly goes out from the guitar body is very small, so the player can play the guitar anytime and anywhere without disturbing the people around it be able to.

  Further, a chin mounting table (chin mounting unit) 23 is provided at the upper end of the main body unit 22 for the performer to place his / her chin on the performance. The jaw mounting table 23 is a flat plate and is formed in a substantially rectangular shape with wood. Specifically, the lateral width of the chin mounting table 23 is about 12 cm, which is the same as the lateral width W21 of the head 221 of the main body 22, the longitudinal width is about 5.5 cm, and the thickness is about 1.8 cm. As shown in FIGS. 6 to 9, the chin mounting table 23 is disposed so as to protrude toward the performer in a state where it is laid down horizontally. The chin mounting table 23 is fixed to the upper end of the main body 22 with screws.

  Further, a chest support 50 is provided at a predetermined position of the head 221 of the main body 22 facing the performer's chest. The chest support 50 is for supporting the guitar body 10 with the performer's chest. When the performer plays the guitar, the guitar is stabilized by placing the chest support 50 on the chest. As the chest support portion 50, a plate-shaped wood is used and a substantially rectangular shape is used. Specifically, as shown in FIGS. 8 and 9, the chest support 50 has a lateral width W3 of about 18 cm, a longitudinal width H3 of about 5 cm, and a thickness of about 1.8 cm. As shown in FIG. 8, the chest support 50 protrudes closer to the performer than the chin rest 23. In order to attach the chest support part 50 to the main body part 21, for example, a screw, an adhesive, or the like can be used.

  As described above, in this embodiment, since a total of three support portions, that is, the leg support portion 30, the arm support portion 40, and the chest support portion 50, are provided, the player can perform a normal acoustic guitar having a resonance body. The guitar of this embodiment can be held and played with the same hold feeling as when playing.

  As shown in FIGS. 6 to 9, the ear pad 21 has a flat plate shape, and includes a head 211 and a leg 212 connected to the lower end of the head 211. As shown in FIG. 7, the thickness D4 of the ear pad 21 is about 1.8 cm. The head 211 is formed in a substantially rectangular shape that is at least larger than the size of the ear. Specifically, as shown in FIGS. 7 and 8, the horizontal width W41 of the head 211 is about 9 cm, and the vertical width H41 is about 12 cm. Further, the leg portion 212 is formed in a long and narrow rectangular shape. Specifically, as shown in FIGS. 7 and 8, the lateral width W42 of the leg 212 is about 2 cm, and the length H42 in the vertical direction is about 12 cm. The lower end portion of the leg portion 212 is fixed to the side surface of the angle adjustment plate 223 of the main body portion 22 with a screw 213 so as to be rotatable in the front-rear direction in FIG. 7 (the left-right direction in FIG. 8). Here, the two ear pads 21 and 21 are arranged so that the surfaces of the two heads 211 and 211 are opposed to each other. The player simply adjusts the inclination angle of the ear pad in the front-rear direction of the performer simply by applying force to each ear pad 21 and 21 and rotating the ear pad around the screw 213. Can do. Thus, the performer can adjust the angle of the ear pads 21 and 21 to reliably bring the ear pads 21 and 21 close to his / her ears during performance.

  In the guitar according to the present embodiment, the vibration transmission unit 20 having such a configuration is provided so that the vibration of the string transmitted from the body unit 11 to the main body unit 22 is received from the head (upper end portion) 221 of the main body unit 22. It can be transmitted to the parts 21 and 21. However, when sound vibrations are transmitted through an object, the greater the mass of the object, the greater the resistance to vibration transmission. For this reason, it is desirable to reduce the weight of the vibration transmission unit 20 as much as possible. The ear pads 21 and the main body 22 are not formed in a rectangular shape as a whole, but are used in which the legs are formed in an elongated rectangular shape and the width of the legs is reduced as much as possible. For this reason. In the present embodiment, wood is used as the material of the body part 11, the ear pad parts 21 and 21, and the main body part 22 which is lighter than metal or the like. 11 and the vibration transmission unit 20 are prevented from being greatly attenuated, and the vibration of the string is reliably transmitted to the ear pads 21 and 21.

Next, how to use the guitar of this embodiment will be described.
First, the performer adjusts the length from the mounting position of the main body 22 to the head 221 and the angle of the main body 22 so that the vibration transmitting unit 20 matches the posture of the player during performance. Specifically, the performer slightly loosens the male screw 24 so that the head portion 221 of the main body portion 22 is positioned in the vicinity of his / her face, and the chin rest 23 is positioned at substantially the same height as his / her jaw. Further, the length from the attachment position of the main body portion 22 to the head portion 221 and the angle between the direction from the attachment position of the main body portion 22 toward the head portion 221 and the longitudinal direction of the neck portion 12 are adjusted. Thus, when the length from the attachment position of the main body portion 22 to the head portion 221 and the angle of the main body portion 22 are determined, the performer fastens the male screw 24 and fixes the vibration transmitting portion 20 to the guitar main body 10.

  Next, the performer rotates the angle adjusting plates 223 and 223 about the screws 226 and 226 so that the distance between the two ear pads 21 and 21 is equal to the distance between the ears. The angle of inclination of each ear pad 21, 21 in the left-right direction is adjusted. Further, by rotating the ear pads 21 and 21 around the screws 213 and 213 so that the two ear pads 21 and 21 come to the position of their ears at the time of performance, in the front-rear direction of FIG. The inclination angle of each ear pad 21, 21 is adjusted.

  When the adjustment work of the vibration transmitting unit 20 is thus completed, the performer can play the guitar of the present embodiment. FIG. 10 is a diagram showing a state where the performer is playing the guitar of the present embodiment. As shown in FIG. 10, the performer puts his head between the two ear pads 21, 21 and places his chin on the chin rest 23. At this time, each ear comes in light contact with the corresponding ear pad 21. The performer plays the guitar in this state.

  When the performer plays the guitar with the ear pads 21 and 21 in close proximity to both ears, the vibration of the strings vibrates the body 11 via the bridge 14. And the vibration of the trunk | drum 11 is transmitted to the ear pad parts 21 and 21 via the main-body part 22 fixed to the trunk | drum 11. The vibration of the ear pad vibrates the air to produce sound, and the performer can hear the sound of the guitar at the ear. Here, in this embodiment, since the two ear pads 21 and 21 are provided, the performer can hear the sound from the ear pads 21 and 21 with both ears. In this way, since the vibration of the string is directly transmitted to the performer's ear through the trunk portion 11 and the vibration transmitting portion 20, the performer vibrates the string from a low tone to a high tone unlike the sound heard through the headphones. Can hear a loud sound faithful to. Further, in the guitar of the present embodiment, the vibration transmitting unit 20 is made of wood, so that the player hears a sound close to the tone of an existing wooden acoustic guitar. In fact, the sound heard by the performer is a sound that is not defeated by the live sound emitted from a normal acoustic guitar. In addition, since the guitar of this embodiment does not have a resonance body, the raw sound which goes out directly from the guitar main body 10 is very small.

  In addition, when the performer plays the guitar with the ear pads 21 and 21 in close proximity to both ears and with the chin placed on the chin mount 23, the music is transmitted from the main body 22 to the chin mount 23. The vibration of the string is transmitted from the jaw bone through the skull to the player's auditory organ by bone conduction. For this reason, the performer can hear the sound which combined the sound from an ear, and the sound by bone conduction. As described above, in the guitar according to the present embodiment, the sound caused by bone conduction can be heard, so that the hearing impaired person can enjoy playing the guitar. In particular, when the guitar according to the present embodiment is used as a guitar dedicated to a hearing impaired person, for example, a portion to be held by the mouth may be provided instead of the chin mounting table 23. In this case, the ear pad 21 is not necessarily provided.

  The guitar of the present embodiment does not include a resonance drum, but two ear pads and two ear pads are attached to the upper end (head), and the upper end (head) is the face of the performer. By providing a vibration transmitting portion having a main body portion attached to the back surface of the body portion so as to be located in the vicinity, when the player plays the guitar with the ear pad portion close to the ear, The vibration vibrates the trunk portion via the bridge portion, and the vibration is transmitted to the ear pad via the main body portion fixed to the trunk portion. The vibration of the ear pad vibrates the air to produce sound, and the performer can hear the sound of the guitar at the ear. As described above, in this embodiment, the vibration of the string is not converted into an electric signal using a pickup as in an electronic guitar or the like, but the vibration of the string is directly played through the trunk portion and the vibration transmitting portion. Since the sound is transmitted to the listener's ears, the performer can hear a loud sound faithful to the vibration of the string from low to high, unlike the sound heard with headphones. In addition, the guitar body does not have a resonance body, and the live sound that directly goes out from the guitar body is very small, so the player can play the guitar anytime and anywhere without disturbing the people around it be able to.

  Further, in the guitar of the present embodiment, the main body portion has a length from the attachment position where the main body portion is attached to the back surface of the body portion to the upper end portion, and a direction from the attachment position toward the upper end portion and the length of the neck portion. The player can easily adjust the position of the ear pad to the position of his / her ear by adjusting the length and angle of the main body by adjusting the angle with the direction. be able to. Further, the ear pad is configured so that the tilt angle in the front-rear direction of the performer and the tilt angle in the left-right direction of the performer can be adjusted, so that the player adjusts the angle of the ear pad. Thus, it is possible to ensure that the ear pad is in close proximity to one's ear during performance.

  In addition, this invention is not limited to said embodiment, A various deformation | transformation is possible within the range of the summary.

  For example, in the above embodiment, the case has been described in which the ear rest is configured such that the tilt angle of the player in the left-right direction can be adjusted, but the ear rest does not necessarily have to be configured in this way. Specifically, as the head of the main body, a head whose horizontal width substantially matches the interval of the performer's face, and two ear pads may be attached to the side of the head.

  Moreover, although said embodiment demonstrated the case where a vibration transmission part had two ear pad parts, you may make it provide only one ear pad part in a vibration transmission part. In this case as well, the performer can hear a loud sound that is faithful to the vibration of the string from low to high. However, in practice, it is desirable to provide two ear pads. This is because the performer can hear the sound from the ear pad with both ears, and can feel the spread of the sound as compared with the case where only one ear is applied to the ear pad.

  Further, in the above embodiment, the case where the body part, the ear pad part, and the main body part are made of wood has been described. However, if the material can reliably transmit the vibration of the sound without greatly attenuating, the body. The part, ear pad and main body may be made of any material. For example, plastic or the like can be used as the material of the body part, the ear pad part, and the main body part.

  Further, in the above embodiment, the case where the guitar of the present invention includes the leg support portion, the arm support portion, and the chest support portion has been described. What is necessary is just to provide at least 1 support part among the support parts. With at least one support, the guitar can be played in a stable state. Further, these three support portions are irrelevant to the sound quality and the volume of the sound, and can be omitted.

  Further, in the above-described embodiment, the case where the guitar of the present invention includes one vibration transmission unit has been described, but the guitar of the present invention can include two or more vibration transmission units. Now, a guitar including two vibration transmission units will be described as a modification of the present invention. FIG. 11 is a schematic perspective view of a guitar which is a modification of the present invention.

  As shown in FIG. 11, the guitar according to the modification of the present invention includes a guitar body 10, two vibration transmission parts 20 a and 20 b, a leg support part 30, an arm support part 40, and a chest support part 50. , 50 and a connecting member 60. Here, each of the two vibration transmitting portions 20a and 20b is the same as the vibration transmitting member 20 in the guitar of the above embodiment. The guitar of this modification is different from the guitar of the above embodiment in that it includes two vibration transmission portions 20a and 20b, and a hook-like connecting member for connecting the two vibration transmission portions 20a and 20b. 60. Other configurations are the same as those in the guitar of the above embodiment. In addition, in the modification of this invention, the same description is abbreviate | omitted by attaching | subjecting the same code | symbol to what has the same function as the thing of the said embodiment.

  The connecting member 60 is in the shape of an elongated hook and is made of wood. For example, the length of the connecting member is about 80 cm. A single hole (not shown) larger than the axis of the male screw 24 is formed at the right end of the connecting member 60. Further, a female screw 61 corresponding to the male screw 24 is embedded in the left end portion of the connecting member 60 so that the end surface thereof is exposed.

  About one vibration transmission part 20a, the main-body part 22 is attached to the back surface of the trunk | drum 11 via the connection member 60. FIG. That is, the male screw 24 is screwed into the female screw 111 embedded in the back surface of the body portion 11 through the long hole 222a of the vibration transmitting portion 20a and the hole of the connecting member 60. Moreover, about the other vibration transmission part 20b, the main-body part 22 is attached to the predetermined location of the connection member 60 different from the attachment location of one vibration transmission part 20a. That is, the male screw 24 is screwed into the female screw 61 of the connecting member 60 through the long hole 222a of the other vibration transmitting portion 20b. Note that a plurality of female screws may be embedded in the connecting member 60. In this case, the distance between the two vibration transmission portions 20a and 20b can be changed by changing the attachment location of the other vibration transmission portion 20b.

  Thus, in the guitar of the modification of the present invention, the main body portion 22 of one vibration transmission portion 20a is attached to the back surface of the body portion 11 via the connecting member 60, and the main body portion 22 of the other vibration transmission portion 20b is attached. By attaching to the connecting member 60, the vibration of the string can be transmitted to the two vibration transmitting portions 20a and 20b via the connecting member 60. For this reason, when a player plays a guitar with the ear pad 21 or 21 of one vibration transmission unit 20a in close proximity to his / her ear, a person other than the performer transmits the other vibration to his / her ear. If the ear pads 21 and 21 of the unit 20b are brought close to each other, a person other than the performer can hear a large sound faithful to the vibration of the strings and can enjoy playing the guitar together with the performer.

  In the guitar of the above-described embodiment, the case where a plurality of strings are stretched between the plurality of pegs and the bridge portion has been described. However, it is sufficient that at least one string is stretched.

  As described above, in the guitar according to the present invention, since the vibration of the string is directly transmitted to the player's ear through the body part and the vibration transmission part, the player is different from the sound heard through the headphones, You can hear a loud sound faithful to the vibration of the string from low to high. Moreover, the guitar body does not have a resonance body, and the raw sound directly coming out from the guitar body is very small. Therefore, when the guitar according to the present invention is used, even when practicing at night or when there is a family around, it is possible to enjoy playing the guitar without any hesitation.
